The Difficulty with Localization of Rectal Cancer after Neoadjuvant Chemoradiation Therapy
Authors: Torres Marla L. , McCafferty Michael H. , Jorden Jeffrey
Published: June 2020

Neoadjuvant chemoradiation therapy (NCRT) has become the standard treatment for locally advanced rectal cancer. Subsequent downstaging can make identification of the primary tumor challenging. Complete pathologic response rates of 8 per cent to 27 per cent are seen with current NCRT regimen. Two patients were referred to our institution after NCRT and subsequent low anterior resection in whom no residual cancer was found in the resected specimen but who manifested cancer in the distal rectum in the early postoperative period. Resection of a locally advanced rectal cancer after NCRT associated with significant tumor shrinkage is facilitated by the surgeon's evaluation with proctoscopy and tumor tattooing before the initiation of NCRT. After NCRT, preoperative proctoscopy, distal rectal evaluation after a sphincter sparing procedure in the operating room, and thorough specimen evaluation help to insure that the surgeon has removed the rectal cancer with an appropriate margin. These cases emphasize how important it is for the surgeon to be involved in the staging phase of managing the patient with rectal cancer.
Defining Hypotension in Moderate to Severely Injured Trauma Patients: Raising the Bar for the Elderly

Published: June 2020

Hypotension, defined as systolic blood pressure less than 90 mm Hg, is recognized as a sign of hemorrhagic shock and is a validated prognostic indicator. The definition of hypotension, particularly in the elderly population, deserves attention. We hypothesized that the systolic blood pressure associated with increased mortality resulting from hemorrhagic shock increases with increasing age. The Los Angeles County Trauma Database was queried for all moderate to severely injured patients without major head injuries admitted between 1998 and 2005. Several fit statistic analyses were performed for each systolic blood pressure from 50 to 180 mm Hg to identify the model that most accurately defined hypotension for three age groups. The optimal definition of hypotension for each group was determined from the best fit model. A total of 24,438 patients were analyzed. The optimal definition of hypotension was systolic blood pressure of 100 mm Hg for patients 20 to 49 years, 120 mm Hg for patients 50 to 69 years, and 140 mm Hg for patients 70 years and older. The optimal systolic blood pressure for improved mortality in hemorrhagic shock increases significantly with increasing age. Elderly trauma patients without major head injuries should be considered hypotensive for systolic blood pressure less than 140 mm Hg.

Published: June 2020

Increased use of thoracic CT (TCT) in diagnosis of blunt traumatic injury has identified many injuries previously undetected on screening chest x-ray (CXR), termed “occult injury.” The optimal management of occult rib fractures, pneumothoraces (PTX), hemothoraces (HTX), and pulmonary contusions is uncertain. Our objective was to determine the current management and clinical outcome of these occult blunt thoracic injuries. A retrospective review identified patients with blunt thoracic trauma who underwent both CXR and TCT over a 2-year period at a Level I urban trauma center. Patients with acute rib fractures, PTX, HTX, or pulmonary contusion on TCT were included. Patient groups analyzed included: 1) no injury (normal CXR, normal TCT, n = 1337); 2) occult injury (normal CXR, abnormal TCT, n = 205); and 3) overt injury (abnormal CXR, abnormal TCT, n = 227). Patients with overt injury required significantly more mechanical ventilation and had greater mortality than either occult or no injury patients. Occult and no injury patients had similar ventilator needs and mortality, but occult injury patients remained hospitalized longer. No patient with isolated occult thoracic injury required intubation or tube thoracostomy. Occult injuries, diagnosed by TCT only, have minimal clinical consequences but attract increased hospital resources.

Published: June 2020

Selective arterial radioembolization with Yttrium-90 (Y-90) microspheres has shown promise for regional management of hepatocellular cancer (HCC). Our objective was to report our early experience with this treatment modality from a nontransplant center. Treatment of patients with HCC was discussed in a multidisciplinary tumor board. Patients with unresectable disease resulting from high lesion number, ill location of the tumor, poor hepatic reserve, or medical comorbidities were offered Y-90 treatment. Liver treatment was either lobar or tumor-targeted. Response to therapy was assessed by CT scan obtained within 3 months using Response Evaluation Criteria in Solid Tumors criteria. During 2007 to 2009, 40 Y-90 radioembolizations were performed in 20 patients with age that ranged from 16 to 87 years; four patients were 80 years old or older. After the first therapy, CT assessment of the treated area showed stable disease (n = 15), partial response (n = 3), and progression (n = 2). Of the two patients who progressed, one was retreated with a subsequent complete response. The other patient died of progressive disease. The most common side effects were mild fatigue, anorexia, and nausea. In summary, our nontransplant center experience shows that Y-90 radioembolization is a well-tolerated treatment in select patients with unresectable HCC with an associated high rate of local tumor control.
Axillary Recurrence is Low in Patients with Breast Cancer who do not Undergo Completion Axillary Lymph Node Dissection for Micrometastases in Sentinel Lymph Nodes

Published: June 2020

Completion axillary lymph node dissection (CLND) is presently the standard of care after a positive sentinel lymph node biopsy (SLNB). We hypothesize that the incidence of axillary recurrence in patients who do not undergo CLND for micrometastases is low, and CLND is not necessary for locoregional control. We performed a retrospective chart review of patients with invasive breast carcinoma and micrometastases detected on SLNB. The Memorial Sloan Kettering Nomogram (MSKN) predicting the likelihood of nonsentinel lymph node (NSN) metastases was compared with the incidence of positive NSN. There were 61 patients identified with a mean follow-up of 70 months. The average tumor size was 2 cm. The median number of positive SLNs was one. Twenty-eight (46%) patients had a CLND; of these, 20 patients had one positive NSN (2 of 28 [7%]) and the mean MSKN score was 12 per cent. There were 33 (54%) patients who had SLNB alone, and their mean MSKN score was 13 per cent. Axillary recurrence in this group was 1.6 per cent. We conclude the incidence of axillary recurrence in patients with micrometastases detected by SLN biopsy who do not undergo CLND is low. The use of a predictive nomogram to estimate likelihood of metastatic disease to NSN may overestimate the actual incidence of positive NSN in patients with micrometastases.

Published: June 2020

Infected pancreatic necrosis (IPN) continues to be a challenging problem for the surgeon. We reviewed the experience on a hepatobiliary surgical service with patients who required operative intervention for IPN with emphasis on surgical approach, timing of surgery, and complications. Between 2002 and 2008, 21 patients underwent surgery for IPN. The initial surgical approach in these 21 patients included either direct pancreatic debridement (DPD, n = 13) or transgastric debridement using cyst-gastrostomy (CG, n = 8). Fifteen patients (71%) required only a single procedure, whereas three (14%) required two procedures and three (14%) required three procedures. The mean time from onset of pancreatitis to operation was 77 days. Patients requiring a single intervention had a longer interval from onset of pancreatitis to surgery compared with those requiring multiple interventions. When comparing CG and DPD groups, there was a longer interval from onset of pancreatitis to debridement, a lower chance of needing multiple debridements, and fewer pancreatic fistulae in the CG group. Overall survival was 95 per cent. Our results demonstrate that CG can be successfully used in select patients with IPN. Patients undergoing CG are less likely to require repeat surgical debridement and to develop pancreatic fistulae compared with patients undergoing DPD.
Surveillance with Serial Serum Carcinoembryonic Levels Detect Colorectal Cancer Recurrences in Patients who are Initial Nonsecretors
Authors: Holt Alicia , Nelson Rebecca A. , Lai Lily
Published: June 2020

Serum carcinoembryonic antigen (CEA) levels, elevated in a subgroup of patients with colorectal cancer (CRC) at presentation, are serially followed as part of recommended surveillance after initial resection. The value of following serial CEA levels in patients who initially present with less than or normal levels of CEA (nonsecretors) is controversial. This study sought to determine the use of follow-up CEA levels in nonsecretors. A retrospective review was performed of patients with resected Stage I, II, and III CRC. We excluded patients who did not have a pretreatment CEA level, at least two follow-up CEA levels, or in whom CEA levels did not normalize after resection. The patients were grouped by initial CEA values: CEA 5 ng/mL or less (nonsecretors) and CEA 5 + ng/mL: (secretors). We identified 186 patients with CRC; 146 were initial nonsecretors. We identified 22 patients with recurrent colorectal cancer; 6 were secretors and 16 patients were nonsecretors. In the secretors group, CEA was elevated with recurrence in four (66%) of the patients. In the nonsecretors, CEA was elevated with recurrence in eight (50%) of the patients. In summary, many recurrences of CRC are marked by an elevation of CEA regardless of whether the patients initially presented as secretors or nonsecretors.

Published: June 2020

The use of Drotrecogin alfa (DAA) (Xigris) in select patients with sepsis has had demonstrable improvement in survival, though its benefit in necrotizing soft tissue infections (NSTI) is unclear. A retrospective review of NSTI patients receiving DAA at our institution from 2006 to 2009 was performed. Our previously derived mortality prediction model, based on classification and regression tree analysis, was applied to patients and the predicted mortality was compared with the actual mortality rate. Ten patients with severe NSTI received DAA. The median admission values were: white blood cell count of 27,000/mm3, serum lactate of 4.0 mmol/L, and serum sodium of 128 mEq/L. Four (40%) patients had systemic complications, five (50%) patients required amputation, and one died (10%). Median time to DAA administration was 12 hours after debridement. There were no bleeding complications attributed to DAA use. Mortality in this series of severe NSTI was only 10 per cent, which compares favorably with the predicted mortality of 18 per cent based on classification and regression tree analysis ( P = 0.2). A prospective, randomized study is warranted to determine if the use of DAA should be part of the standard therapy for NSTI patients with a predicted high mortality.
Axillary Recurrence after Sentinel Lymph Node Biopsy for Breast Cancer

Published: June 2020

Sentinel lymph node biopsy (SLNB) is routinely performed as an axillary staging procedure for breast cancer. Although the reported false-negative rate approaches 10 per cent, this does not always lead to axillary recurrence. We previously reported an axillary recurrence rate of 1 per cent at a median follow-up of 2 years. Our objective is to determine the rate of axillary recurrence with longer follow-up. A retrospective review of patients with invasive breast cancer and a negative SLNB treated between 2001 and 2005 was performed. Cases where neoadjuvant therapy was used or where isolated tumor cells (ITCs) were found were included, whereas those with fewer than 18 months of follow-up were excluded. One (0.7%) out of 139 patients had an axillary recurrence after a median follow-up of 52 months. No patient who underwent neoadjuvant chemotherapy or with ITCs had axillary recurrence. Twelve (8.6%) patients have died, with death attributed to breast cancer in three. Our study demonstrates that axillary recurrence after SLNB remains a rare event after a median follow-up of 52 months, despite including potentially higher risk scenarios such as where neoadjuvant chemotherapy is used and ITCs are found. Therefore, axillary lymph node dissection can safely be avoided in patients where SLNB is negative.
Abdominal Surgery after Lung Transplantation

Published: June 2020

Among 450 patients who underwent lung transplantation (LuT) between April 1994 and April 2009 at a single academic hospital, 75 received surgical consultation, and 52 underwent 65 abdominal operations. Operations included colectomy (17), cholecystectomy (14), exploratory laparotomy (10), ulcer repair (five), hernia repair (four), Nissen fundoplication (four), pancreatic debridement (four), ostomy takedown (two), drainage of intra-abdominal abscess (two), and major vascular procedure, gastrostomy, splenectomy, fascial closure, laparoscopic common bile duct exploration, and small bowel resection (one each). Fourteen patients (27%) died within 30 days of surgery. On univariate analysis, age, race, comorbidities, history of previous abdominal surgery, transplant type, and timing of surgery after transplant were similar between the patients who survived and died. On multivariate analysis, emergent surgery, multiple medical comorbidities, and male gender were predictive of 30-day mortality ( P ≤ 0.05). Ulcer repair, major vascular procedures, pancreatic surgery, splenectomy, and exploratory laparotomy were associated with ≥ 50 per cent 30-day mortality. This is the largest series reporting outcomes of abdominal operations after LuT. Elective operations in LuT patients are safe, whereas emergent operations carry an extremely high short-term mortality rate. Aggressive prophylaxis for ulcer disease and early elective intervention for potential surgical problems, such as gallstones and uncomplicated diverticulitis, should be considered.
Outcomes of Minimally Invasive Esophagectomy without Pyloroplasty: Analysis of 109 Cases

Published: June 2020

Pyloroplasty is performed during esophagectomy to avoid delayed gastric emptying. However, studies have shown that gastric function is minimally impaired even without a pyloroplasty when a gastric tube rather than the whole stomach is used for reconstruction. The aim of this study was to evaluate outcomes of minimally invasive esophagectomy without performance of a pyloroplasty. We performed a retrospective review of 145 patients who underwent a minimally invasive esophagectomy. The 30-day mortality was 2.1 per cent with an in-hospital mortality of 3.4 per cent. Of the 140 patients with more than 90 days follow-up, 31 patients had a pyloroplasty and 109 patients did not. One (3.2%) of 31 patients with pyloroplasty versus six (5.5%) of 109 patients without pyloroplasty developed delayed gastric emptying. There was no significant difference in the leak rate between the two groups (9.7% vs 9.6%, respectively). Total operative time was significantly shorter in the group without pyloroplasty (360 vs 222 minutes with a pyloroplasty, P < 0.01). Patients with delayed gastric emptying responded well to endoscopic pyloric dilation or Botox injection. The routine performance of a pyloroplasty during minimally invasive esophagectomy can be safely omitted with a reduction in operative time and minimal adverse effects on postoperative gastric function.

Published: June 2020

Admission indicators for monitored care in gallstone pancreatitis have been lacking. Recently, we established three criteria for admission to intensive care unit or step down versus ward beds: 1) concomitant cholangitis, 2) heart rate > 110 beats/min, and 3) blood urea nitrogen > 15 mg/dL. The purpose of this study was to determine whether these criteria would be effective in decreasing monitored care bed utilization without adversely affecting outcomes. A retrospective review of all patients with gallstone pancreatitis at a public teaching hospital was performed (2003-2009). A comparison was made of patients before (2003-2005, Period 1) and after (2006-2009, Period 2) establishment of monitored care triage criteria. Over the study period, there were 379 patients. The median Ranson score for both periods was 1. The median ages were 41 and 39, ( P = 0.7). In Period 1, 28 per cent of patients were admitted to the intensive care unit/step down unit versus 12 per cent in Period 2. None of the patients required transfer from the ward to a monitored care setting in Period 2. There were no mortalities in either period. In conclusion, the presence of concomitant cholangitis, heart rate >110, and blood urea nitrogen > 15 are useful and safe triage criteria for admission to a monitored care setting. Use of these criteria significantly decreased monitored care bed utilization and resulted in fewer mis-triages without adversely affecting patient outcomes.

Published: June 2020

Colorectal cancer (CRC) is third in mortality rate amongst Asian Americans. However, CRC characteristics in this patient population have been poorly defined. A retrospective review at an urban tertiary hospital located in an underserved region was performed to determine CRC characteristics for Asian Americans in comparison to other races. Four hundred fourteen patients were represented by Hispanics (n = 161), African Americans (n = 101), Asians (n = 83), and Whites (n = 69). The majority of Asian American patients (n = 70,84%) presented with a left-sided lesion. This proportion was higher than that seen in African Americans (59%, P < 0.0003), Hispanics (66%, P < 0.0033), and Whites (63%, P < 0.0036). Thirty-six Asian American patients presented with Stage III disease which was the most frequent presenting stage for this patient population and also statistically higher than all the other races. Furthermore, Asian Americans in this study still presented predominantly with left-sided lesions and in a more advanced stage. These findings suggest a potential benefit of initially offering flexible sigmoidoscopy given the decreased compliance among Asian Americans to obtain routine CRC screening. Ultimately, this modality may be more acceptable, leading to higher compliance for CRC screening in Asian Americans without likely degradation in cancer detection rates.

Published: June 2020

Multidisciplinary therapy (MDT) of node-positive rectal cancer is considered optimal. We performed a retrospective cohort study of node positive rectal cancer patients diagnosed between January 1, 1994 and December 31, 2003 in Region 5 of the California Cancer Registry to determine the impact of MDT on disease specific survival (DSS). During the study period, 398 patients with stage III rectal cancer were identified. Only 251 patients (63.1%) received radiation (XRT). Patients receiving XRT had significantly improved survival when compared with those who did not (5 year DSS 55% with XRT vs 36% without XRT, median follow-up 43 months, P < 0.001). There was no statistically significant difference in T stage ( P = 0.41), the number of N1 patients ( P = 0.45), or the number of positive nodes harvested (mean 11.5 w/o XRT vs 12.8 w/XRT, P = 0.37) between patients receiving XRT and those who did not. Patients receiving XRT were far more likely to receive systemic chemotherapy (83% vs 27%, P < 0.0001). Multidisciplinary therapy of node-positive rectal cancer is associated with improved DSS. However, substantial numbers of node positive rectal cancer patients are not receiving MDT. Greater efforts are needed to implement consistent multidisciplinary algorithms into rectal cancer management.
Staging Accuracy of Endoscopic Ultrasound Based on Pathologic Analysis after Minimally Invasive Esophagectomy

Published: June 2020

Endoscopic ultrasonography (EUS) is a common staging modality used in patients with esophageal cancer. The objective of this analysis was to evaluate the accuracy and sensitivity of EUS in determining the depth of penetration (T stage) and nodal status (N stage) in patients with esophageal cancer who underwent minimally invasive esophagectomy (MIE). A retrospective analysis of all patients at a university hospital who underwent preoperative EUS followed by MIE for cancer was performed. We compared the results of preoperative EUS to final pathologic analyses of the esophageal specimen, examining the accuracy of EUS staging. Ninety-five patients with esophageal cancer who underwent MIE had preoperative EUS. Twenty-four of the 95 patients were excluded for lack of a repeat EUS after neoadjuvant therapy before resection. Hence, 71 patients were evaluated for the accuracy of EUS staging. The accuracy of EUS for TO disease was 80 per cent; T1 disease was 75 per cent; T2 disease was 39 per cent; and T3 disease was 88 per cent. The overall EUS accuracy for T stage was 72 per cent with overstaging occurring mostly for pathologic T1 tumors in 18 per cent and understaging occurring mostly for pathologic T3 tumors in 11 per cent. The sensitivity and specificity for detection of nodal involvement were 79 per cent and 74 per cent, respectively. However the accuracy for T and N staging by EUS after neoadjuvant therapy decreased to 63 per cent and 38 per cent, respectively. Endoscopic ultrasound in the absence of neoadjuvant therapy is a relatively accurate and sensitive modality for determining the depth of tumor penetration and the presence of nodal disease in patients with esophageal carcinoma. The accuracy for T and N staging is less reliable after neoadjuvant therapy.
Nonsteroidal Anti-inflammatory Drug Colopathy Mimicking Malignant Masses of the Colon: A Report of Three Cases and Review of the Literature
Authors: Margolius David M , Cataldo Thomas E.
Published: June 2020

The adverse effects of nonsteroidal anti-inflammatory drugs (NSAIDs) on the colon have been reported as a wide spectrum of symptoms, signs, and endoscopic findings. Despite the extensive use of NSAIDs, and the potential seriousness of NSAID colopathy, this condition often goes unrecognized or misdiagnosed. We report three cases of NSAID colopathy in which the diagnosis of malignancy was incorrectly made based on endoscopic findings. Before any surgical intervention, we entertained the diagnosis of NSAID colopathy based on clinical presentation. Ultimately, in two of the three cases, surgery was avoided and the lesions resolved. We present their clinical course and a review of the pertinent literature reviewing theories of the pathophysiology, the range of clinical presentations, and the pathological findings of this entity.
The Impact of Facility Volume/Size on Breast Cancer Treatment and Outcome
Authors: Sariego Jack
Published: June 2020

Recent studies have suggested that outcomes and survival from breast cancer are improved when definitive treatment is rendered at high-volume and/or teaching centers. Consolidation of such cases in tertiary centers, however, is often impractical and impossible. Patients often desire primary treatment of their breast cancer in their own communities. The current study was undertaken to examine the impact of treatment facility type on the treatment performed as well as on overall survival. Breast cancer treatment and survival data were available from the American College of Surgeons National Cancer Data Base. Only patients in whom no previous treatment had been rendered were included in the analysis. Data were stratified with regard to type and size of treatment facility/hospital; stage distribution; initial treatment performed; and 1-, 2-, and 5-year survival. A total of 665,409 patients were included in the current analysis. There were no significant differences in stage distribution between facility types nor was there a significant difference in the treatment performed (although there was a slight trend toward breast conservation at the larger centers). This was true overall and for each stage of cohort. There were also no significant differences in 1-, 2-, and 5-year survival rates overall and at any stage (although again, there was a slight trend toward a minimal survival advantage at the larger centers). There was no significant impact of facility size or type on either breast cancer treatment performed or overall survival. There was no evidence that more “advanced” treatments were offered at larger centers nor was there evidence of improved outcome/survival at larger centers. Care can be rendered safely, efficiently, and effectively in the community setting.

Published: June 2020

The authors review their experience with thoracic esophageal perforation at Inova Fairfax Hospital, June 1, 1988, to March 1, 2009. With the exception of 6 patients with occult perforation, all of whom survived with nonoperative therapy, aggressive surgical intervention was the standard approach. Among patients treated aggressively with surgery within 24 hours of perforation, hospital survival was 97 per cent versus 89 per cent for patients treated aggressively surgically after 24 hours. In the absence of phlegmon, implacable obstruction, or delay, primary repair resulted in 100 per cent survival. Where phlegmon or resolute obstruction existed, resection and reconstruction resulted in 96 per cent survival. Even when patients were deemed too ill to undergo surgery, cervical diversion was 100 per cent effective in eradicating continuing leak and achieved 89 per cent survival. Endoesophageal stenting was applied as primary treatment or secondarily such as where leak complicated primary repair. When stenting was used as the initial and primary treatment modality, survival was 88 per cent. Targeted drainage was helpful on occasion as an adjunct to initial therapies. Comfort measures alone were appropriate when clinical circumstances merited no effort at resuscitation. Finally, survivors were asked to self-categorize their ability to swallow; 95 per cent responded good to excellent.

Published: June 2020

Laparoscopic surgery has become the elective approach for the surgical treatment of gastroesophageal reflux disease in the last decade. Outcome data beyond 10 years are available for open fundoplication, with good-to-excellent results, but few studies report long-term follow-up after laparoscopic fundoplication. We performed a retrospective study of all the patients that underwent laparoscopic Nissen and Toupet fundoplications as antireflux surgery between 1995 and 1998 in our institution. To evaluate the long-term results, a face-to-face interview was performed in 2009. One hundred and six patients were included in the study. Surgical techniques performed were Nissen fundoplication (NF) in 56 patients and Toupet (TF) in 50. Complication rate was 4 per cent in both groups (nonsignificant [NS]). Two patients (4%) of NF required reoperation because of dysphagia. After 10 years, 10 per cent of the patients remain symptomatic in both groups. Fifteen per cent of NF take daily inhibitors of the proton pump versus 14 per cent of TF (NS). Twenty per cent of NF refer dysphagia, all of them without evidence of stenosis at endoscopy or contrasted studies. The satisfaction rate of the patients was 96 per cent in NF and 98 per cent in TF. Laparoscopic Toupet fundoplication seems to be as safe and long-term effective as Nissen, but with a lower incidence of postoperative dysphagia. In our experience Toupet fundoplication should be the elective approach for the surgical treatment of gastroesophageal reflux disease.
Spontaneous Rupture of Hepatic Artery Aneurysm Associated with Polyarteritis Nodosa

Published: June 2020

Polyarteritis nodosa (PAN) is a vasculitis, which often involves small and medium sized visceral arteries. This condition may result in multifocal aneurismal formation and end-organ damage. Uncommonly, PAN may present with rupture of hepatic artery aneurysms. Here, we report a rare case of a ruptured intrahepatic aneurysm associated with PAN. A 79-year-old woman presenting with abdominal pain had CT scan of the abdomen, which revealed hematoma in the right hepatic lobe. Visceral angiogram confirmed pseudo-aneurysm of a right hepatic arterial branch, and this was managed with endovascular coil embolization. The diagnosis of PAN was made and corticosteroid therapy was initiated. We also performed a literature review to define this condition's demographics, clinical presentations, and appropriate management. The review revealed 17 published cases of ruptured PAN-related intrahepatic aneurysms. We conclude that unexplained findings of visceral arterial aneurysms should prompt investigations for vasculitis as the etiology.
Subcutaneous Linea Alba Fasciotorny, Does it Really Work?

Published: June 2020

Subcutaneous linea alba fasciotorny (SLAF) is a minimally invasive treatment method for abdominal compartment syndrome initially used in severe acute pancreatitis (SAP). A retrospective analysis of the first 10 patients with SAP undergoing SLAF was performed to analyze the effect and outcome of this decompressive procedure. The mean age of the patients was 46 (range 33-61) years. SLAF was performed 1 to 17 days postadmission, in six cases within 48 hours. The mean (range) preoperative intra-abdominal pressure was 31 (23-45) mm Hg and immediate postoperative intra-abdominal pressure was 20 (10-33) mm Hg. The mean decrease was 10 (2-17) mm Hg and the decompressive effect was considered sufficient in six cases. A completion laparostomy within 24 hours was required in four cases. The mean preoperative Sequential Organ Failure Assessment score was 12 (4-17) and 11 (1-20) 1 to 5 days postoperatively. The decrease was five or more score points in three patients with successful SLAF. The overall mortality and morbidity rates were 4/10 and 2/10; no complications were attributed to the SLAF itself. It is concluded that SLAF is a safe decompressive technique in SAP-related abdominal compartment syndrome. The initial effect is sufficient in about half of the patients. A completion midline laparostomy is required in the nonresponders.
Pietro Loreta and His Contribution to Surgery in the 19th Century
Authors: Aldini Nicolò Nicoli , Fini Milena , Giardino Roberto
Published: June 2020

Pietro Loreta (1831 to 1889), head of surgery at the University of Bologna, Italy, is at present a little-known name. However, in the field of surgery in the second half of the 19th century, his contributions to various areas, especially that of bladder stone treatment and gastric surgery, aroused great interest also at the international level. This survey focuses on both of these subjects that are particularly indicative of Loreta's activity. While he was trying to improve the operation of perineal cystotomy, which was about to be abandoned, he was faced with the new frontier of gastrointestinal tract surgery. Surgery was in rapid transformation, and the practice of a general surgeon still encompassed the domains of different surgical specialities, which would develop individually afterward. Loreta was a pupil of the outstanding surgeon Francesco Rizzoli and some of his pupils such as Alessandro Codivilla and Bartolo Nigrisoli became heads of surgery. His attitude of caution, that he recommended in his writings, is more remarkable considering his problematic nature and might be the most significant and original trait of Loreta's personality.
Proportion of Patients with Critical Limb Ischemia who Require an Open Surgical Procedure in a Center Favoring Endovascular Treatment
Authors: Gargiulo Nicholas J. , O'Connor David J.
Published: June 2020

Endovascular interventions have gained widespread acceptance as primary and secondary treatments for critical lower extremity ischemia (CLI), and many believe there is little need for open bypasses for CLI. Despite this, some patients presenting with CLI require traditional lower extremity bypass procedures at some point for successful limb salvage. To determine the proportion of patients requiring an open procedure, we reviewed our 1-year experience with CLI patients at a center committed to endovascular approaches whenever possible. We reviewed all patients presenting with CLI from January 1, 2007 to December 31, 2007. CLI was defined as ischemic rest pain, nonhealing ulceration, or gangrene for which a major amputation was imminently required. All patients underwent duplex and conventional angiography before intervention. Endovascular treatments were favored as primary, secondary, or tertiary treatments, if possible. If these failed or were impossible, standard lower extremity bypasses were performed. One hundred and forty-eight patients presented with primary, secondary, or tertiary CLI over this 1-year period. Of these, 63 (42%) were treated successfully with an endovascular intervention, and 69 (47%) required standard lower extremity bypass, and 16 (11%) required a combined endovascular and open procedure (i.e., hybrid procedure). Of these 148 patients, 46 (31%) were presenting with secondary, tertiary, or more CLI after failed previous (1-5) procedures. Despite the initial enthusiasm that the majority of patients presenting with CLI may be treated with endovascular procedures, there exists a significant cohort of patients that will ultimately require standard open surgical procedures.

The aims of this study were to clarify the distribution and spread pattern of metastatic nodes and to evaluate the importance of the number, ratio, and location of positive nodes in ampullary adenocarcinoma. We analyzed the clinicopathologic data and survival of 52 patients who received curative pancreatoduodenectomy for ampullary adenocarcinoma between June 1994 and May 2009. Metastatic lymph nodes were found in 32 (61.5%) patients. The median number of evaluated nodes and positive nodes were 26 (range 10-60) and two (range 1-15), respectively. The most commonly involved nodes were the posterior pancreaticoduodenal nodes (26 patients) followed by the anterior pancreaticoduodenal nodes (11 patients). No positive hepatoduodenal and common hepatic artery nodes were found. In univariate analysis, number of positive nodes, and their ratio and location were significantly associated with survival. Only the factor of three or more metastatic nodes had the independent power in predicting a poor outcome in multivariate analysis ( P < 0.001). Ampullary adenocarcinoma first spreads to the posterior pancreaticoduodenal nodes and then the anterior nodes. The number of positive lymph nodes, rather than their ratio and location, independently affects survival after curative resection in patients with ampullary carcinoma.

The combination of respiratory insufficiency, right heart failure, and depth of shock is thought to result in mortality approaching 100 per cent after pneumonectomy. We did a retrospective review of patients requiring pneumonectomy over 6 years. Data collected included demographics, emergency department and operating room course, critical care management, complications, and mortality. Seven patients were identified. Mean age was 26.5 years. Five sustained penetrating and two sustained blunt trauma. Mean Injury Severity Score was 26 and Revised Trauma Score was 4.4. Mean admission systolic blood pressure, lactate, and pH were 98 mm Hg, 10.1 mmol/L, and 6.98, respectively. Mean time to operation was 49 minutes. Mean estimated blood loss was 5.4 liters and mean intraoperative transfusion was 13.1 units of packed red blood cells. All seven developed right heart failure. Four required prone ventilation, one oscillating ventilation, four continuous renal replacement, and three extracorporeal membrane oxygenation. Four patients died (57%); two of refractory right heart failure within the first 24 hours and two of multiple organ failure on postoperative days 9 and 138. Mean length of stay in survivors was 71 days. All survivors were neurologically intact and none required mechanical ventilation at discharge. The need for pneumonectomy after trauma is rare. Patients undergoing pneumonectomy who present in extremis require significant intra and postoperative support, with a survival of 42 per cent.

The spectrum of critical illness-related corticosteroid insufficiency (CIRCI) in trauma is not fully defined. This study describes our trauma experience with hydrocortisone-treated patients experiencing CIRCI. We conducted a 5-year retrospective analysis from a Level II trauma center using biochemical and clinical criteria for adrenal insufficiency. Seventy patients met the inclusion criteria for CIRCI. There was a 34 per cent mortality rate despite therapy. Nonsurvivors were older with larger admission base deficits and experienced higher rates of sepsis, bacteremia, and pneumonia. Nonsurvivors had prolonged vent days (mean 53 ± 64 days) when compared with survivors (mean 30 ± 22 days; P = 0.029). Renal replacement therapy was a strong predictor of mortality. Spinal cord-injured patients had high Injury Severity Scores (mean 34 ± 18), elevated baseline Cortisol levels (mean 56 ± 84 vs 18 ± 14; P = 0.004), and required prolonged duration of steroid therapy (30 ± 52 vs 15 ± 15 days; P = 0.080) when compared with the nonspinal cord-injured group. Our data suggest that CIRCI in trauma is associated with significant mortality and morbidity even when patients are treated appropriately.

We hypothesized that full-time orthopedic traumatologists would increase interfacility transfer patients with pelvic ring injuries at a trauma center seeking American College of Surgeons Level I verification. A trauma registry query identified 790 patients with pelvic ring injuries admitted to a trauma service over 10 years. The study groups included 173 patients 3 years before and 405 patients 3 years after recruitment of two full-time orthopedic traumatologists. Interfacility transfers of patients with pelvic ring injuries requiring operative procedures were increased over 230 per cent ( P < 0.01) with full-time orthopedic traumatologists. Financial analysis showed enhanced hospital margin per patient and decreased direct costs ( P < 0.01). Complications, mortality rates, and length of stay were decreased ( P < 0.01). Full-time orthopedic traumatologists enhance pelvic ring injury patient interfacility transfers, operative procedures, outcomes, and financials at a Level I trauma center in a rural setting.
Mesh Repair for Midline Ventral Hernia Without Lateral Fixation of the Mesh
Authors: Kubalak Gary
Published: June 2020

The Rives-Stoppa repair is the current standard of care for the open treatment of midline ventral hernia. Transfascial, lateral fixation of the mesh has always been considered an important part of this technique. I reviewed cases of patients with a primary or recurrent midline, ventral hernia who had an open repair using the Rives-Stoppa technique with the exception of mesh fixation. Heavy weight polypropylene mesh was sutured to the midline of the posterior rectus sheath with two to three interrupted stitches. Multiple metal clips were attached to the periphery of the mesh for later identification. Physical exams and CT scans were done on all patients postoperatively to assess the integrity of the repair. From November 2008 to January 2010 13 patients had an open repair using a modified Rives-Stoppa technique. All patients had an intact repair based on physical exam and a contiguous rectus abdominis muscle layer based on CT evaluation. Lateral fixation of heavy weight polypropylene mesh is not necessary when performing a retro-muscular repair using the Rives-Stoppa technique.

This report examines outcomes of revascularization for acute arterial mesenteric ischemia (AAMI) using the American College of Surgeons National Surgical Quality Improvement Program database. Patients with International Classification of Diseases, 9th Revision and Current Procedural Terminology codes indicating AAMI with concomitant mesenteric revascularization were identified. Demographic, risk factor, procedural, morbidity, and mortality data were examined. Associations with morbidity and mortality were analyzed by logistic regression. One hundred forty-two cases of AAMI were identified. Seventy-one cases were thrombotic and 71 were embolic according to revascularization codes. Mean age was 66 years, 84 per cent of patients were white, and 54 per cent were female. Unadjusted major morbidity and mortality rates were 69 and 30 per cent, respectively. Patients with thrombotic AAMI were more likely to have a lower body mass index, greater than 10 per cent weight loss in the past 6 months, and a history of smoking. Patients with embolic AAMI were more likely to present emergently with sepsis. Unadjusted morbidity and mortality rates were 78 and 38 per cent for embolic and 61 and 23 per cent for thrombotic AAMI, respectively. Multi-variable predictors of morbidity included bowel resection at the time of revascularization, transfer admission, and involvement of a surgical resident. Multivariable predictors of mortality included impaired functional status, increased age, and postoperative sepsis. Cause of AAMI was not a significant predictor of morbidity or mortality. In a large sample of AAMI cases, AAMI remained a highly lethal and morbid condition. Predictors of morbidity and mortality included indicators of advanced presentation, treatment delay, and patient-related factors specific to AAMI, including debility and advanced age. Efforts directed at prevention and increasing the speed of diagnosis and definitive treatment appear to be necessary to improve outcomes.

The open components separation technique (CST) for hernia repair allows for autologous tissue repair with approximation of the midline fascia in patients with complex hernias. CST requires creation of large undermining skin flaps, whereas the endoscopic component separation technique (ECST) is performed without division of the epigastric perforating vessels and may minimize wound morbidity. A review of patient demographics and outcome measures of patients undergoing CST and ECST between November 2008 and February 2010 was performed. Twenty-five patients were identified who underwent either CST (14 patients) or ECST (11 patients). There were no differences in body mass index (CST 34.8 kg/m2, ECST 37.5 kg/m2, P = 0.45), operating room times (CST 268 minutes, ECST 252 minutes, P = 0.54), or hospital length of stay (CST 5 days, ECST 5.8 days, P = 0.78). Wound complications occurred less with ECST (9 vs 57%, P = 0.03). The time to resolution of wound complications in ECST was reduced * 1 vs 4 months). No recurrences were seen in either group with a mean follow-up of 4months (range, 1 to 12 months). ECST and CST require similar operative times and hospital lengths of stay. ECST is associated with reduced wound complications compared with CST. Short-term recurrence rates with CST and ECST are comparable.
