Published: June 2020

The Stop the Bleed (STB) course teaches trainees prehospital hemorrhage control with a focus on mass education. Identifying populations most likely to benefit can help save on the significant cost and limited resources. In this study, we attempted to identify those populations and performed a cost analysis. Trainees underwent STB education and completed a survey on completion to assess demographics and prior experiences where STB skills could have been useful. Five hundred seventy-one trainees categorized as first responders (14%), students (56%), and the working public (30%) completed the survey. Most trainees found the lecture and simulation helpful, 96 per cent and 98 per cent, respectively. There were significant differences among groups who had previously been in situations where the STB course would have been helpful (88% first responders versus 40% students versus 43% public workers) ( P < 0.001). Teaching a class of 10 students costs approximately $455; the cost can be as high as $1246 for a class of 50 students. Most STB trainees found the course helpful. First responders are most likely to be exposed to situations where course information could be helpful. Focusing on specific high-yield groups rather than mass education might be a more efficient approach to STB education.

To characterize both emergency room (ER) and hospital discharge dispositions of patients presenting with farm-related injuries. The 2012 National Trauma Data Bank was queried in August 2017 for injuries occurring on a farm. Patients were stratified by gender, age group, race, Injury Severity Score (ISS), and injury type. We performed logistic regression analysis to correlate parameters with likelihood of discharge home or death. P values < 0.05 were considered significant. Five thousand six hundred thirty-one patients were identified, the majority of whom were male (72%) and white (85%). The most common mechanisms of injury included animal-related (29%), followed by falls, vehicles, and other causes. The highest ISSs were seen in vehicular injuries (11% ISS of 251) and the greatest fatality rate was seen in machinery injuries (4%). Four thousand seven hundred fifty-three (84%) patients were admitted to the hospital, and 4056 (72%) were discharged home from the ER or after hospitalization. One hundred thirty patients (2%) died of their farm-related injury. Most patients presenting to the ER with farm-related injuries survive, are admitted to the hospital, and are ultimately discharged home. Few patients die of their injuries. Animal injury is most common and machinery injury most lethal of farm trauma patients presenting to the ER.

Published: June 2020

Thromboelastography (TEG) has become a critical tool for the diagnosis, assessment, and management of hyperfibrinolysis and coagulopathy in trauma. In 2015, Chapman et al. of the Denver group coined the term “Death Diamond” (DD) to describe a TEG tracing identified in a unique trauma population. The DD was associated with a 100 per cent positive predictive value for mortality. Given the potential prognostic implications and resource savings associated with validating the DD as a marker of futile care, we sought to further evaluate DD outcomes. A retrospective review of 6850 TEGs, 34 patients (24 trauma and 10 nontrauma), displayed a DD tracing. Through invasive procedures and transfusions, nine DD tracing “normalized,” but, ultimately, this did not impact the outcome because the DD had a positive predictive value of 100 per cent for mortality in both populations. The median survival time in trauma patients was two hours compared with seven hours in nontrauma patients. Overall, this study further validates the predictive value of the DD in a trauma population while also serving as an assessment of the DD in a nontrauma population. Given these findings, a DD may prove to be an indicator of futile care. Further multicenter studies should be conducted to confirm these results.

Published: June 2020

The operative experience of present-day surgical residency training has evolved as a result of the contributions of laparoscopic surgery. Some traditional open procedures are now more descriptive and less of a familiarity to many general surgery residents (GSRs). The aim of this study was to investigate how open operative experience compares with laparoscopy for GSRs. A retrospective, multicenter, consecutive cohort study of all patients undergoing surgical intervention involving the appendix and gallbladder identified from the ACS-NSQIP database over a 2.5-year period. All GSR postgraduate year-level operative experience was recorded. Of 777 procedures, 13 laparoscopic appendectomy conversions to open (4.3%) by Rocky-Davis (15%) or lower midline (84.6%) incisions were performed versus 285 that remained laparoscopic (95.6%). Fifty (10.4%) open cholecystectomies (38 open + 10 conversions + 2 common bile duct (CBD) exploration), 27 (5.6%) laparoscopic cholecystectomies with cholangiogram, and 402 (83.9%) laparoscopic cholecystectomies were performed. Twenty-nine different GSRs participated in procedures. Eighty-five (10.9%) operations were performed with multi–postgraduate year levels. Surgical residents have an unequal operative experience for case-specific open procedures. A competency-based system to demonstrate a resident's hands-on surgical skills is fundamental to residency training and should be considered for specific types of low-volume open surgical cases.
Substance Abuse–Related Soft Tissue Infections: A Uniquely Complicated Subset of a Common Problem
Authors: Tsai Jonathon , Suh Lily , Annie Frank , Richmond Bryan K.
Published: June 2020

We hypothesize that soft tissue infections (SSIs) related to intravenous drug usage (IVDU) are associated with a more complicated and costly course than those not associated with IVDU. For the period 2005–2018, ICD 9/ICD 10 billing codes were used to identify patients admitted with SSIs and their causes/complications and associated costs. IVDU-related infections were then compared with non-IVDU–related infections. t test was used to compare treatment costs and length of stay. Logistic regression analysis was used to assess the likelihood/risk of specific events in the IVDU versus non-IVDU populations. Of 47,281 patients admitted with SSIs, 1323 were associated with IVDU. IVDU-related patients tended to be younger (36.2 vs 49.3 years, P = 0.001). Both cost and length of stay were significantly greater in the IVDU group ($30,471 vs $16,020, P = 0.001; 5.7days vs 3.7days, P = 0.001). In addition, IVDU admissions were more likely to be associated with chronic blood-borne infections (hepatitis B/C, HIV, P = 0.001) and a significantly greater incidence of secondary infectious complications, including endocarditis ( P = 0.001), bacteremia ( P = 0.001), and osteomyelitis ( P = 0.003). SSI admissions related to IVDU are a unique subgroup of patients. These patients not only have longer and more costly lengths of stay but are also at higher risk for secondary complications such as chronic blood-borne viral illness and secondary bacterial infectious complications, such as bacteremia, endocarditis, and osteomyelitis. Further prospective study of these findings is warranted as we continue to battle the growing problem of IVDU in the United States

Published: June 2020

Older adults account for an increasing percentage of trauma patients and have worse outcomes when compared with younger populations. Simple prediction tools are needed to designate risk categories among these patients. The Geriatric Trauma Screening Tool (GTST) was developed to risk stratify older adults admitted to the ICU at a Level 1 trauma center. One hundred fifty patients aged ≥ 65 years were prospectively screened for high-risk (HR) injuries, comorbidities, and pre-hospital function using the GTST. Patients who screened for HR were more likely to have an unfavorable disposition than non-HR patients. HR patients had significantly longer ICU and hospital length of stays when compared with non-HR patients. In addition, patients with prior functional impairment were at higher risk for an unfavorable discharge disposition than their counterparts. Implementation of the GTST predicted discharge disposition in geriatric trauma patients admitted to the ICU. Pre-injury functional status was a better predictor of discharge disposition than either the types of HR injuries or the presence of comorbidities. Risk stratification of geriatric trauma patients allows for early engagement of patients and caregivers regarding transitions of care as well as more efficient utilization of hospital resources.
Does Distance to Transplant Center Affect Post Kidney Transplant Readmission Rates?

Published: June 2020

Many transplant recipients travel long distances to their transplant center with challenging access to their transplant team. As such, many centers keep recipients near to the center for a period immediately after discharge from the transplant admission. Thus far, the correlation between distance to the transplant center, readmission, and outcomes has not been described. The aim of this study was to examine this relationship. Patients undergoing deceased donor kidney transplant at a single center over a three-year period were analyzed via retrospective chart review for factors associated with distance to the transplant center and readmission. P values < 0.05 were considered significant. Of 141 patients, the overall 90-day readmission rate was 38.3 per cent, and rates were similar between nonlocal and local recipients. Nonlocal were more likely whites (66.1% vs 45.6%; P = 0.032) and from rural areas (56.5% vs 13.9%; P < 0.001). Length of stay was similar between groups, as were rates of delayed graft function. Non–death-censored graft survival was higher at one and three years for nonlocal patients (96.8% and 96.8% vs 89.7% and 78.4%; P = 0.016). This remained significant after adjusting for baseline differences between the groups (hazard ratio (HR) for graft failure = 0.195, 95%, P = 0.046). Patients who live remotely from the transplant center do not experience higher rates of readmission or worsened outcomes, and thus may be managed safely at home. Interestingly, graft survival is improved in nonlocal patients. This may reflect the urban nature of the area surrounding our transplant center, but warrants further study for conclusions to be reached.

Published: June 2020

Total thyroidectomy (TT) or near-TT (NTT) is often recommended over medical management for the treatment of Graves’ disease (GD). We assess the safety within surgical subspecialties at our institution for TT/NTT in GD patients. A retrospective review of patients undergoing TT/NTT for GD was performed from 2004 to 2016. Patient factors, thyroid size, surgeon subspecialty, and intraoperative/postoperative outcomes were all reviewed. Multivariate analyses were used to determine risk factors for complications. A total of 383 patients underwent TT/NTT. Two hundred thirty-three patients underwent TT/NTT by otolaryngology (n = 233, 60.8%), surgical oncology (n = 140, 36.6%), general surgery (n = 8, 2.1%), and unknown (n = 2, 0.5%). On multivariate analysis, surgical duration was longer for males ( P = 0.001) and increased thyroid weights ( P = 0.001). No association with hypocalcemia or recurrent laryngeal nerve paralysis was found with factors considered. No factors were found to be associated with the ability to identify the recurrent laryngeal nerve. Estimated blood loss (EBL) was increased in younger patients (0.010), males ( P = 0.001), increased BMI ( P = 0.012), and increased thyroid weight ( P < 0.001). EBL was also associated with the physician performing the operation, where EBL was greatest for TT/NTT performed by general surgeons, followed by surgical oncologists and then by otolaryngology ( P = 0.006). TT/NTT is safe and a reasonable option for the treatment of GD.
Thromboelastogram-Guided Resuscitation for Patients with Traumatic Brain Injury on Novel Anticoagulants

Published: June 2020

Traumatic brain injuries in patients on antithrombotic agents carry significant morbidity. Initial therapy is centered around reversal of these agents. The thromboelastogram (TEG) maps the clotting cascade to guide reversal. A retrospective chart review was conducted for 118 patients presenting with a traumatic brain injury while on antithrombotics. Patients were divided between those who received a TEG on arrival and those who did not. The primary endpoint was overall mortality. Secondary endpoints included blood product utilization, and outcomes associated with specific novel anticoagulants. Mortality in the control group was 20.3 per cent compared with 18.5 per cent in the TEG group ( P = 0.81). For less severe injuries, the control group mortality was 3.8 per cent and the TEG group mortality was 8.7 per cent ( P = 0.64). For more severe injuries, mortality in the control versus TEG groups were 31.6 per cent and 25.8 per cent, respectively ( P = 0.73). Blood product utilization was significantly lower in the TEG group ( P = 0.002). Overall mortality was not significantly different between the groups. However, when stratified by severity of injury, mortality was reduced in the TEG-guided group in severely injured patients. Blood product utilization was significantly reduced with TEG-guided reversal. Trauma centers can improve the utilization of blood products in reversal of antithrombotics with the use of TEG.

Published: June 2020

Delayed splenic bleeding (DSB) is a poorly understood complication of blunt splenic injury. Treatment for splenic bleeding may involve splenectomy, but angioembolization is becoming a widely used adjuvant for management. Using the North Carolina Trauma Registry, this study aimed to evaluate the incidence, mortality, and risk factors for DSB in North Carolina. Using ICD-9 and ICD-10 codes, patients were stratified into two cohorts, those who underwent immediate splenectomy and those who were initially managed nonoperatively. DSB was then defined as splenectomy at greater than 24 hours after presentation. Of the 1688 patients included in the study, 269 patients (16%) underwent immediate splenectomy and 1419 (84%) were managed nonoperatively initially, with 32 (2%) having delayed splenectomy. Older age (≥30 years) was associated with increased odds of having delayed splenectomy (odds ratio 4.30; 95% confidence interval 1.08, 17.17; P = 0.04). Four per cent of patients managed nonoperatively and undergoing an angioembolization procedure eventually required splenectomy. Risk factors for DSB remain elusive. Splenic artery embolization may be used as an adjuvant to splenectomy for stable patients, but it is not always a definitive treatment, and patients may still require splenectomy.

Published: June 2020

Selection of orthotopic liver transplantation (OLT) candidates is increasingly inclusive of patients with high BMI. We aim to characterize the influence of obesity on the surgical outcome measures of prolonged operative time and unplanned reoperation. We reviewed the records of obese and normal weight OLT recipients over a 10-year period from a single institution. Variables that trended ( P < 0.1) with endpoints on univariate analysis were put into multivariate logistic regression models to determine independent association ( P < 0.05). We included 195 obese and 171 normal weight OLT recipients in our study. On multivariate analysis, obesity was the only preoperative risk factor that trended with unplanned reoperation (odds ratio 2, P = 0.05). Similarly, only obesity remained independently associated with prolonged length of operation (defined as ≥275 minutes) on multivariate analysis (odds ratio 1.7, P = 0.04). In summary, obesity may make OLT more technically challenging and, thus, represents an independent risk factor for unplanned reoperations and prolonged operative time.

Published: June 2020

Regionalizing surgical care to high-volume centers has improved outcomes for endocrine surgery. This shift is associated with increased travel time, costs, and morbidity within certain patient populations. We examined travel time–related differences in demographics, health-care utilization, thyroid-specific disease, and cost for patients undergoing thyroid surgery at a single high-volume center. Data were extracted from the 2005 to 2014 ACS-NSQIP and clinical data repository for patients undergoing thyroid surgery. Travel times between patients’ home address and the hospital were calculated using Google Earth under assumptions of standard road conditions and speed restrictions. Travel time was divided into <2 hours versus ≥2 hours. Primary outcomes were hospital cost and 30-day morbidity. Factors associated with travel time and primary outcomes were analyzed using appropriate bivariate tests and multivariable regression modeling. A total of 1046 thyroid procedures were included, with median (IQR) travel time of 68.8 (40.1–107.2) minutes. Eight hundred forty-seven (80.9%) patients traveled <2 hours compared with 199 (19.1%) traveled ≥2 hours. Patients traveling ≥2 hours were more likely to have complex thyroid disease (37.7% vs 27.6%, P = 0.005), uninsured status (31.1% vs 11.8%, P < 0.001), lower preoperative morbidity risk (2.3% vs 2.7%, P = 0.02), and longer length of stay (1.21 vs 1.07 days, P = 0.04), but similar median operative times (163 vs 165 minutes, P = 0.89). Average cost was higher for patients traveling ≥2 hours ($7300 vs $6846 [2014 USD], P = 0.05). Despite observed patient differences, hospital costs and postoperative morbidity did not differ after adjustment. Existing management practices and the nature of the disease process may be protective against the potential negative effects of regionalization.

Published: June 2020

Postoperative pain managed with opioids has contributed to the opioid crisis through over-prescribing practices. We assessed opioid-prescribing habits and their use by patients undergoing surgery for cutaneous malignancies. An Institutional Review Board–approved retrospective analysis was conducted for patients who underwent skin cancer resection between January 2018 and June 2018. Data were collected from the electronic medical record, and opioid-related data were collected from patient interviews and state registries. There were 120 study participants (42 females and 78 males) with a median age of 67 years (range, 21–94 years). All received preincision local anesthetic: 64 had liposomal bupivacaine (LB) (53%) and 56 had non-LB bupivacaine (47%). Most participants (n = 88) used 0 opioids (73%), including 43 LB-anesthetic (67%) and 45 non–LB-anesthetic (80%). No significance was seen between those with a diagnosis of chronic pain, narcotic tolerance, an area of resection, and nodal sampling groups in opioid use. Four patients (3%) requested a refill. Of 105 prescriptions written for opioids, 99 had leftover opioids for an over-prescribing rate of 94 per cent. This study suggests pain after skin cancer surgery is manageable with very limited opioid requirements. Our results support prescribing no more than five opioid tablets for postoperative pain control in patients undergoing resection for skin malignancies.

Enmeshment of emergency trauma providers (ETPs) into the United States health-care fabric resulted in the establishment of a formalized surgical critical care fellowship and certification for emergency medicine trainees. The aim of this study was to compare trauma outcomes for surgery-trained providers (STPs) and ETPs at our institution, hypothesizing patient outcome equivalency. We performed an institutional review board–exempt institutional registry review (January 1, 2004 to August 1, 2018), comparing 74 STPs and 6 ETPs. Comparator variables included all-cause mortality, all-cause morbidity, CTimaging studies per provider, time in ED (min), hospital/ICU lengths of stay, ICU admissions, and functional outcomes on discharge. Statistical comparisons included chi-square test for categorical data and analysis of covariance for continuous data (adjustments made for patient age, Injury Severity Score, and trauma mechanism; all P < 0.20). Statistical significance was set at P < 0.05, with an equivalence study design. A total of 33,577 trauma resuscitations were reviewed (32,299 STP-led and 1,278 ETP-led). Except for patient age (STP 50.2 ± 25.9 vs ETP 54.9 ± 25.3 years), Injury Severity Score (8.47 ± 8.14 vs 9.22 ± 8.40), and ICU admissions (16.1% vs 18.8%), we noted no significant intergroup differences. ETPs’ performance was equivalent to that of STPs for all primary comparator variables (mortality, morbidity, CT utilization, time in the ED, lengths of stay, and functional outcomes). Incorporation of ETPs into our trauma center resulted in outcome parity between ETPs and STPs, while simultaneously expanding the expertise and experiential diversity within our multidisciplinary team. This study provides support for further incorporation of ETPs as equal partners across the growing network of United States regional trauma centers.
Laparoendoscopic Single-Site (LESS) versus Robotic “Redo” Hiatal Hernia Repair with Fundoplication: Which Approach is Better?

Published: June 2020

Only a small percentage of patients fail laparoscopic fundoplications undertaken for gastroesophageal reflux disease. But because many laparoscopic fundoplications have been undertaken, surgeons frequently encounter patients in need of “redo” operations. This study was undertaken to evaluate the robotic approach versus laparoendoscopic single-site (LESS) approach for redo fundoplications. With an Institutional Review Board approval, 64 patients undergoing LESS (n = 32) or robotic (n = 32) redo antireflux operations were prospectively followed up. Data are presented as median (mean + SD). For LESS versus robotic redo operations, the operative duration was 145 (143 ± 33.5) versus 196 (208 ± 76.7) minutes ( P < 0.01), estimated blood loss was 50 (80 ± 92.1) versus 20 (43 ± 57.1) mL ( P = 0.07), and length of stay was 1 (3 ± 5.4) versus 1 (2 ± 1.9) day ( P = 0.57); 1 LESS operation was converted to “open.” Operative duration was longer for men ( P = 0.01). Postoperative complications were not more frequent after Nissen (n = 36) or Toupet (n = 28) fundoplication, regardless of the approach. When matched by BMI, operative duration was prolonged by a large Type I to IV hiatal hernia ( P = 0.01). Symptoms improved dramatically and were similar with both approaches, and patient satisfaction was high. Robotic redo antireflux operations take longer than LESS operations. LESS and robotic redo antireflux operations are both safe and offer significant and similar amelioration of symptoms after failed fundoplications.

Published: June 2020

Enhanced recovery after surgery (ERAS) may improve patients’ postoperative course. Our center implemented the ERAS protocol for the colorectal service in 2016, and then expanded to multiple service lines over the course of 1.5 years. Our aim was to determine whether broad implementation of ERAS protocols across different service lines could improve patient care. All ERAS patients from 2018 were captured prospectively. For each service line using ERAS, one full year of data preceding ERAS was compared. ERAS service lines included colorectal, gynecology laparoscopic, gynecology open, hepatopancreaticobiliary, urology – nephrectomy and cystectomy, spinal fusion, cardiac surgery—coronary artery bypass grafting. ERAS and pre-ERAS services were compared based on length of stay (LOS), complications, readmission, and mortality rates. In addition, hospital costs were collected during this time frame. ERAS protocols significantly decreased LOS for colorectal, gynecology, and spine. Complications were significantly decreased in colorectal, gynecology, urology, and spine. Readmissions did not significantly increase in any service line except spine. There was no significant change in mortality. ERAS proved to save the hospital 1847 days and cost saving of almost $5 million in 2018. Implementing ERAS broadly improved patient outcomes (LOS, complications, readmission, and mortality) while providing cost savings to the hospital.

Published: June 2020

The objective of this study was to examine the association between surgeon characteristics, procedural volume, and short-term outcomes of hemodialysis vascular access. A retrospective cohort study was performed using Medicare Part A and B data from 2007 through 2014 merged with American Medical Association Physician Masterfile surgeon data. A total of 29,034 procedures met the inclusion criteria: 22,541 (78%) arteriovenous fistula (AVF) and 6,493 (22%) arteriovenous graft (AVG). Of these, 13,110 (45.2%) were performed by vascular surgeons, 9,398 (32.3%) by general surgeons, 2,313 (8%) by thoracic surgeons, 1,517 (5.2%) by other specialties, and 2,696 (9.3%) were unknown. Every 10-year increase in years in practice was associated with a 6.9 per cent decrease in the odds of creating AVF versus AV G ( P = 0.02). Surgeon characteristics were not associated with the likelihood of vascular access failure. Every 10-procedure increase in cumulative procedure volume was associated with a 5 per cent decrease in the odds of vascular access failure ( P = 0.007). There was no association of provider characteristics or procedure volume with survival free of repeat AVF/AVG or TC placement at 12 months. A significant portion of the variability in likelihood of creating AVF versus AVG is attributable to the provider-level variation. Increase in procedure volume is associated with decreased odds of vascular access failure.
Debris Flow Syndrome: Injuries and Outcomes after the Montecito Debris Flow
Authors: Langdon Sarah , Johnson Arianne , Sharma Rohit
Published: June 2020

On January 9, 2018, a catastrophic debris flow devastated Montecito, California. A 30-foot wall of boulders, mud, and debris ran down the hillsides at 15 miles per hour injuring dozens and causing 21 prehospital deaths. A retrospective review was conducted of the victims from the debris flow presenting to Cottage Health. Injury patterns, procedures performed, complications, length of stay, and outcomes were analyzed. Twenty-four patients were evaluated; 15 were admitted. Of the patients admitted, the most common presenting symptoms were soft tissue injuries (100%), hypothermia (67%), craniofacial injuries (67%), corneal abrasions (53%), and orthopedic injuries (47%), as well as loss of an immediate family member during the incident (73%). Procedures included skin irrigation (93%), operative soft tissue debridement (47%), body orifice irrigation due to mud impaction (40%), and orthopedic repair of fractures and ligaments (40%). All survived to discharge. “Debris flow syndrome” can be defined as a pattern of injuries, including soft tissue injuries, hypothermia, craniofacial trauma, corneal abrasions, orthopedic injuries, and mud impaction. Managing the debris flow syndrome requires co-ordinated and specialized care.
Impact of Intraoperative Foley Catheters on Postoperative Urinary Retention after Inguinal Hernia Surgery
Authors: Crain Nikhil , Tejirian Talar
Published: June 2020

Foley catheters (FCs) are often used during inguinal hernia operations; however, the impact of intraoperative FC use on postoperative urinary retention (POUR) is not well understood. We reviewed unplanned returns to the urgent care or ED for 27,012 inguinal hernia operations across 15 Southern California Kaiser Permanente medical centers over 6.5 years. In total, 239 (0.88%) patients returned to urgent care/ED with POUR [235 (98%) men versus 4 (2%) women]. Overall, POUR increased with age ( P < 0.00001). POUR was higher in open repairs using general anesthesia versus local with monitored anesthesia care (0.7% vs 0.3%, P < 0.0001). Of 5,017 laparoscopic operations, 28 per cent had FC use. Although POUR was greater for laparoscopic versus open operations (2.21 vs 0.58%, P < 0.00001), there was no difference in POUR for intraoperative FC versus no FC use in the laparoscopic approach (2.36% vs 2.15%, P = 0.33). For all laparoscopic operations, there was no difference in urinary tract infection within 7 or 30 days when comparing intra-operative FC versus no FC use ( P = 0.28). POUR can be minimized by avoiding general anesthesia for open inguinal hernia repairs, but intraoperative FC use does not affect POUR or urinary tract infection rates for laparoscopic inguinal hernia repair.

Published: June 2020

Chronic abdominal pain of unknown origin is a challenging diagnosis encountered by clinicians. Patients often undergo an extensive workup and long periods of uncertainty without the establishment of a definitive diagnosis. Diagnostic laparoscopy is a relatively safe procedure that can be used as an effective diagnostic and therapeutic tool in treating this disease. This was a retrospective, single-institution study exploring the efficacy of diagnostic laparoscopy in treating chronic abdominal pain of unknown origin. More than 90 per cent of laparoscopies resulted in a positive finding, with adhesions being the most common. A total of 50 per cent of patients experienced resolution of symptoms on follow-up. Patients were overwhelmingly satisfied with their postoperative outcomes and willing to undergo the procedure again with their outcomes in mind.

Published: June 2020

Best management for acute appendicitis (AA) in adults with liver cirrhosis is controversial and needs more investigation. We aimed to examine the impact of different treatment modalities on outcomes in this complex patient population. The Nationwide Inpatient Sample database from 2012 to 2014 was queried to identify AA patients with no cirrhosis, compensated cirrhosis (CC), and decompensated cirrhosis (DC). Each cohort was further stratified according to the treatment type: nonoperative management, open appendectomy, and laparoscopic appendectomy (LA). Chisquare, ANOVA, and binary regression analyses were used to determine differences between groups and risk factors for mortality and complications, with P < 0.05 considered statistically significant. A total of 108,289 AA patients were analyzed; of those, 304 with CC and 134 with DC were identified. Compared with CC and no cirrhosis, DC patients had significantly higher mortality, higher cost, and longer hospital length of stay. LA is accompanied by higher survival, lower cost, shorter duration of hospitalization, and lower incidence of complications across all groups. We conclude that LA is the best management strategy for AA in cirrhotic patients. Even in decompensated cirrhotics, which are associated with worse clinical outcomes, LA is still a favorable option over open appendectomy and nonoperative management.

Published: June 2020

There are conflicting views regarding techniques for repair of small umbilical hernias (UHs). Here, we compare the recurrence rate in primary repair with that reported for mesh repair by examining a single surgeon's practice at a large medical center with a comprehensive electronic medical record. A six-year retrospective review of primary UH repairs between January 2012 and December 2017 at Kaiser Permanente Los Angeles Medical Center was undertaken. Patients were identified through a database search of the electronic medical record. The primary endpoint of UH recurrence was examined; median follow-up was 3.4 years. Primary, elective UH repair was performed in 244 patients; 71 per cent of hernias were small (<2 cm). The total number of recurrences was seven (3%). The t test analysis showed significant differences in the average size of hernia defects between those with recurrences (2 cm) and those without (1.4 cm), P < 0.05. Primary repair affords low infection and recurrence rates, comparable to those reported for mesh repair. Our single-surgeon/large-volume study contributes to the evidence that primary UH repair is a safe and durable method, with low risk of recurrence. The use of absorbable monofilament suture, and selection for lower BMI and smaller hernia sizes proved to be effective.

The use of neoadjuvant chemoradiation therapy in patients with pancreatic adenocarcinoma is emerg-ing as an acceptable therapy option. The effects of neoadjuvant therapy on 30 days’ outcomes in patients with pancreatic cancer are not well defined in the literature. NSQIP (2009–2012) was used. Only patients with a diagnosis of pancreatic cancer and those who underwent a Whipple were included in the analysis. Patient who underwent neoadjuvant chemoradiation therapy were compared with those who did not receive therapy. Main outcome measures were as follows: complications, ≥2 units of blood transfusions, length of stay, readmission rates, return to the operating room, and 30-day mortality. A total of 1445 patients (395: neoadjuvant chemoradiation and 1050: no neoadjuvant therapy) were identified. The mean age was 67 ± 12 years, and 51 per cent of the patients were male. Neoadjuvant chemoradiation therapy was associated with increase in readmission rates (18% vs 12.2%, P 0.02), unanticipated return to the operating room (2.3% vs 1.1%, P 0.03) with no difference in mortality rates. Neoadjuvant chemoradiation therapy is associated with increase in inhospital complications. These differences in outcomes may be explained by the more advance stage of pancreatic cancer in these subsets of patients. Resource utilization and preoperative rehabilitation are of utmost significance to overcome this rise in complications associated with neoadjuvant chemoradiation therapy.

We present a previously undescribed complication after noninvasive ventilation (NIV) for respiratory failure in a patient who required percutaneous endoscopic gastrostomy (PEG) tube placement for long-term nutrition after a complicated coronary bypass operation. A 54-year-old female diagnosed with unilateral vocal cord paralysis after emergent coronary artery bypass grafting (CABG) underwent an uncomplicated PEG tube placement. She was placed on intermittent NIV because of respiratory failure 24 hours after PEG placement, and NIV was continued for several days. Three days later, she was noted to have pneumoperitoneum on an upright chest X-ray. Abdominal CT scan revealed a large amount of pneumoperitoneum with the PEG tube in the correct position and no extravasation of enteric contrast from the stomach. Tube feeds were held and NIV was discontinued. Nonetheless, six days later, the patient was found on CT scan to have partial displacement of the PEG tube with leakage from the gastrotomy requiring operative repair. This case highlights the vulnerability of PEG tubes to management practices in the early postoperative period. Abdominal distention secondaryto NIV likely caused pressure necrosis of the PEG site with dislodgement of the tube. This case elicits considerations regarding future management practices of patients receiving NIV in the early postoperative period after PEG placement.

Postoperative delayed gastric emptying (DGE) is a very common complication after a pancreaticoduodenectomy (PD). This along with other complications can lead to increased health-care costs. This study investigates the costs and length of stay (LOS) associated with these. A retrospective study of 131 patients undergoing PD between 2000 and 2016 at Loma Linda University Health was performed. Chi-squared test was used to determine statistically significant differences between patients with and without DGE (according to the definition of the International Study Group of Pancreatic Surgery). Multiple logistic and linear regression analyses were performed to obtain adjusted odds ratios for variables of interest in association with DGE and relationship to LOS. Of 150 patients undergoing PD, 131 patients with tumors were analyzed. The overall incidence of DGE was 56 per cent. No pre- or postoperative factors were associated with increased risk of DGE. The median LOS for patients with DGE was 15 days versus 9 days for patients without DGE. Patients with DGE added $21,198 to the overall cost of hospitalization. Fourteen patients (10.7%) were readmitted, of whom 11 were because of DGE. Further studies assessing the utility of intraoperative G-tube placement in decreasing hospital costs and readmissions are needed.
Non-Trauma Service Admissions: Should We Care?

The American College of Surgeons Committee on Trauma requires that trauma centers with greater than 10 per cent injured patients admitted to non-trauma services (NTSs) have processes to review these for appropriateness of care. We previously described an algorithm to determine the appropriateness of NTS admissions. Our objective was to determine if the outcome and process of care was similar between TS- and NTS-admitted patients. We conducted a retrospective analysis of our trauma registry. NTS-appropriate patients by algorithm were included. Differences between patients admitted to a TS and an NTS were compared. Nine hundred forty-one patients met the algorithm criteria as appropriate for the NTS; 694 were admitted to TS and 247 to NTS. Contact with TS was the most common association with admission to TS. NTS patients were older and had similar Injury Severity Scores, and a similar proportion had three or greater pre-existing comorbidities. NTS-admitted patients had similar risk for mortality and complications, but longer length of stay, and were less likely to have a desirable discharge disposition. Minimally injured elderly patients constitute most of NTS and a large proportion of TS admissions. NTS admission seems appropriate with respect to mortality and complications. Differences in the care process may have accounted for longer length of stay and differences in disposition destination.

The reality of sexual harassment is unmasking in many fields, and medical trainees constitute a vulnerable and at-risk group. We report the prevalence of sexual harassment among GI, internal medicine, and pediatric residents, with a focus on identifying underlying reasons for lack of victim reporting. A modified previously validated Department of Defense survey on sexual harassment was e-mailed to 261 GI, 132 pediatric, and 271 internal medicine program directors. Three hundred eighty-one residents responded to the survey. Female trainees were more likely to be subject to sexual harassment (83% vs 44%, P <0 .0001). Offensive and/or suggestive jokes and comments were the most common type of harassment experienced. Most residents were unlikely to report the offender (87% females, 93% males). Although 77 per cent of residents believed they would be supported by their program if they reported a sexual harassment event, only 43 per cent were aware of institutional support in place for victims at their program. Although there is a persistently high incidence of harassment in training, the avenues in which to report it are largely unknown and underused. Further research should focus on evidence-based interventions to encourage reporting and to design institutional programs for victims of sexual harassment.

Deep vein thrombosis (DVT) is linked to reimbursements and publicly reported metrics. Some hospitals discourage venous duplex ultrasound (VDUS) screening in asymptomatic trauma patients because they often find higher rates of DVT. We aim to evaluate the association between lower extremity (LE) VDUS screening and pulmonary embolism (PE) in trauma patients. Trauma patients admitted to an urban Level-1 trauma center between 2010 and 2015 were retrospectively analyzed. We characterized the association of asymptomatic LE VDUSs with PE, upper extremity DVT, proximal LE DVT, and distal LE DVT by univariate and multivariable logistic regression controlling for confounders. Of the 3959 trauma patients included in our study—after adjusting for covariates related to patient demographics, injury, and procedures—there was a significantly lower likelihood of PE in screened patients (odds ratio (OR) = 0.02, P < 0.001) and a higher rate of distal LE DVT (OR 11.1, P = 0.004). Screening was not associated with higher rates of proximal LE DVTafter adjustment for covariates (OR = 1.8, P = 0.193). PE was associated with patient transfer status, pelvis fracture, and spinal procedures in unscreened patients. After adjusting for covariates, we have shown that LE VDUS asymptomatic screening is associated with lower rates of PE in trauma patients and not associated with higher rates of proximal LE DVT. Our detailed institutional review of a large cohort of trauma patients over five years provides support for ongoing asymptomatic screening and better characterizes venous thromboembolism outcomes than similarly sized purely administrative data reviews. As a retrospective cohort study with a large sample size, no loss to follow-up, and a population with low heterogeneity, this study should be considered as level III evidence for care management.

Obesity is a major health issue in the modern world population and a risk factor for surgical procedures. This study examined perioperative and oncologic results of gastrectomy in obese patients diagnosed with gastric cancer. BMI ≥30 kg/m2 was used to designate obesity. Five hundred and one patients were operated throughout the study period (2009–2018). The outcomes in obese patients (n = 205) were compared with those with normal weight (n = 171) and overweight (n = 125). The mean BMI was significantly different between the groups: 21.9 versus 26.7 versus 33.3 kg/m2 ( P < 0.01), respectively. Obesity was associated with higher incidence of comorbidities, longer operative time, and increased blood loss. Postoperative and short-term oncologic outcomes were similar. Median follow-up was 24 months with similar recurrence rates in the three groups. Median survival was comparable between the normal weight, overweight, and obese patients—36 (27–45) versus 42 (30–53) versus 32 (17–47) months, respectively ( P = 0.63). Obesity itself does not deteriorate the surgical outcomes of gastrectomy in patients with gastric cancer. Although technically demanding in obese patients, adequate lymph node yield and satisfactory long-term oncologic outcomes can be achieved in this group.
