Effectiveness of an Early Ultrasound Training Curriculum for General Surgery Residents
Authors: Hosseini Motahar , Bhatt Astha , Kowdley Gopal C.
Published: June 2020

Ultrasound (US) is fast becoming an extension of the physical examination in most surgical settings. Unfortunately, few residency programs offer a formal US training curriculum to their general surgical residents. This study aimed to assess the efficacy of a formal US training module for general surgery residents. We studied the degree of improvement observed between junior and senior residents. A training-based study was conducted to evaluate baseline knowledge and skills. Subsequently, a formal didactic and practical training program for our surgery residents was instituted. Residents were then scored in various categories. A total of 18 surgical residents comprising 10 junior and 8 senior residents completed our US training module. There was no significant improvement in the scores of the senior resident group. In the junior group, the written test, image detection, optimization, and interpretation categories improved significantly after completion of the training module. Comparison of improvement in scores between junior and senior residents revealed a significantly better improvement in the junior group than in the senior group. Early training of surgical residents can significantly improve US performance in junior residents. This early training has the benefit of increased utilization of bedside US for diagnostic and procedural purposes. Interestingly, even without formal training, skill acquisition of senior residents is noted to occur during modern surgical training.

Published: June 2020

In 2010, 2.5 million people sustained a traumatic brain injury (TBI), with an estimated 75 per cent being mild TBI. Mild TBI is defined as a Glasgow Coma Scale (GCS) of 13 to 15. Based on recent data and our institutional experience, we hypothesized that mild TBI patients, including patients on aspirin, could be safely managed by trauma surgeons without neurosurgical consultation. Trauma patients admitted to a single Level I trauma center from June 2014 through July 2015 aged 18 years or older were evaluated. Patients with a GCS ≥14, regardless of intoxication, with an epidural or subdural hematoma ≤4 mm, trace or small subarachnoid hemorrhage, and/or non-displaced skull fracture were prospectively enrolled. The primary outcomes were needed for neurosurgical consultation and intervention. Secondary outcomes included readmission rate and neurologic morbidity and mortality rate. Of 1341 trauma admits, 77 were enrolled. No patients required neurosurgical intervention. Only 1/75 (1.3%) patients required neurosurgical consultation. Outpatient follow-up was achieved with 75/77 (97.4%) patients. No mortalities, major neurologic morbidities, or readmissions were observed (95% confidence interval 0–4%). None of the 21 patients on aspirin required neurosurgical intervention and only 1/21 (4.8%) patients required neurosurgical consultation with no mortalities observed at follow-up. Management of mild TBI can be safely accomplished by trauma surgeons without routine neurosurgical consultation. Larger multicenter prospective studies are required to evaluate our finding that this also may be safe in patients taking aspirin.

To evaluate variation in care nationwide for children with splenic injuries at pediatric trauma, adult trauma, and nontrauma centers. We used the National Inpatient Sample from 2001 to 2010 to identify pediatric patients with splenic injury. We analyzed demographic, clinical, and hospital status characteristics. The primary objective was comparison of splenectomy rates at pediatric, adult, and nontrauma centers. We identified 34,599 patients with splenic injury. Throughout the study, 3,979 (11.5%) patients underwent splenectomy: 8.2 per cent of patients at pediatric trauma, 17.6 per cent at adult trauma, and 14.5 per cent at nontrauma centers. Multivariate regression analysis demonstrated patients had decreased odds of splenectomy at pediatric trauma centers compared with adult and nontrauma centers (OR = 0.42, P < 0.001). In addition, children aged 14 to 17 years (OR = 2.5) with injury severity score > 14 (OR = 5.8) had increased odds of undergoing splenectomy. In this nationwide sample, children with splenic injury treated at adult trauma and nontrauma centers had significantly higher rates of splenectomy compared with children treated at pediatric trauma centers. We highlight the need for interventions that ensure all injured children receive appropriate and high quality trauma care.

Published: June 2020

We propose that prolonged colorectal surgery operative times are associated with increased 30-day adverse events. We identified a cohort from the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) from January 2005 through December 2012. Patients who underwent colectomy with primary anastomosis were selected using CPT codes. Operative time was categorized into short, average, and long based on mean operative times 61 SD. NSQIP-approved multivariate models were used to identify associations between operative time and 30-day adverse events. A total of 113,615 patients underwent colorectal resection of which 46 per cent were laparoscopic and 12 per cent were identified as long operative times. Patients with long operative procedures had 34 per cent more superficial surgical site infections, 65 per cent more organ space infections, 69 per cent more abdominal dehiscences, 44 per cent more thrombotic complications, 45 per cent more urinary tract infections, 40 per cent more returns to the operating room, and 36 per cent more prolonged lengths of stay ( P < 0.05 for all analyses). The multivariable analysis revealed an association between long operative times and increased adverse events despite adjustment for all NSQIP recommended covariates. Our results reveal increased 30-day adverse events with increased operative time. We propose that operative time may serve as a proxy for surgical complexity in colorectal surgery.

The pediatric melanoma population is not well described, and current guidelines for their management are not well defined. Our study aims to identify this population, treatment modalities, and outcomes using a national population-based database. We reviewed the Surveillance, Epidemiology, and End Results database (2004–2008). Patients ≤21 years old with melanoma were included and grouped into ≤12 years of age, 13 to 18 years, and 19 to 21 years. Clinical characteristics were analyzed across the groups. A total of 1255 patients were included: 52.7 per cent were 19 to 21 years of age, 36.3 per cent were 13 to 18 years of age, and 11.0 per cent were ≤12 years of age. The 19- to 21-year-olds had the highest proportion of stage I (50.5%) versus ≤12 years of age (31.9%); the ≤12-year-olds had the highest proportion of stage IV (3.6%) versus 19 to 21 years of age (0.9%), P < 0.001. The 19- to 21-year-olds had the highest proportion receiving wide local excisions only (34.8%) versus ≤12 years of age (26.4%); the ≤12-year-olds had the highest proportion of patients without any surgeries (16.0%) versus 13 to 18 years of age (9.4%), P = 0.169. On adjusted analysis, the 19- to 21-year-olds had worse survival compared with ≤12 years of age (hazard ratio: 5.26, P = 0.017, 95% confidence interval 1.34–20.65). Disparities were found in the ≤12-year-old melanoma population, as they had later stage melanomas, less invasive surgery, and lower survival. Clearer prognostic factors are needed to better elucidate their management.

Published: June 2020

Initial implementation and maintenance of an enhanced recovery protocol (ERP) is complex and has not been adequately described. The aim of this study was to investigate the efficacy of an ERP at a tertiary care academic institution. A secondary aim was to identify barriers to implementation and continued protocol compliance (PC) to further decrease length of stay (LOS). Patients undergoing colon resection from February 2, 2011 to December 19, 2014 were compared with patients that followed implementation of an ERP from August 10, 2015 to July 14, 2016. The primary endpoint was LOS. Secondary endpoints were PC, analgesia requirements, time to return of bowel function, and ileus. One hundred and seventy-seven historical controls were compared with 68 ERP patients. LOS was shorter in study patients (4.9 vs 7.1 days for open surgery; 3.3 vs 6.1 for laparoscopic surgery). Intraoperative IVF balance, morphine equivalents, and length of time to return of bowel function were significantly less in the ERP group (1445.89 ± 845.25 mL vs 3006.08 ± 1197.97 mL), (64.48 ± 114.49 vs 232.90 ± 541.47), (2.41 ± 1.32 days vs 3.82 ± 2.00 days). Rate of ileus was less in study patients (4.8 vs 14.7%). The readmission rate and 30-day National Surgical Quality Improvement Program complication rates were not significantly different. PC was negatively associated with LOS (r = -0.35, P = 0.0026). Similar to prior studies, this study demonstrates the efficacy of an ERP. Increased PC is associated with decreased LOS, thus providing further evidence that ERPs should be the standard of care. Scheduled interdisciplinary meetings to discuss patient outcomes and methods to increase PC can help further improve efficacy of ERPs.
Moped Crashes are Just as Dangerous as Motorcycle Crashes

Published: June 2020

Mopeds’ (MP) limited speed gives the impression that they are safer than motorcycles (MCs), but factors other than speed may contribute to crash outcome. Records of patients involved in MC or MP crashes evaluated at the University of Louisville Hospital emergency department between 2010 and 2014 were reviewed. Among patients who required hospital admission, the frequency of rib fractures, hemo- or pneumothorax, abdominal injury, extremity injury, and vertebral body fractures were greater in the MC group, whereas head and facial injuries were more common in the MP group. Positive toxicology screens were equivalent (MC 51.8% vs MP 56.8%, P = 0.25), and fewer MP riders wore helmets (33.8% vs 9.2%, P < 0.01). The injury severity score for MC was higher (15.2 vs 13.9, P = 0.039), but mortality was equivalent between groups (7.5 vs 7.6%, P = 0.98). Among patients discharged from the emergency department with minor injuries, frequency of all injury types were equivalent. Although MC patients had a statistically higher injury severity score, differences were clinically similar with equal mortality rate. Moped riders are just as likely to suffer death or serious injury after a crash compared with MC riders, and injury prevention efforts should be aimed at both groups.

Published: June 2020

Patients with abdominopelvic cancers are at increased risk of venous thromboembolism (VTE) due to their malignancy. We evaluated outcomes and the rate of VTE in patients undergoing abdominopelvic surgery for malignancy with preoperative epidural analgesia without postoperative chemical VTE prophylaxis. A retrospective review between 2009 and 2015 identified 285 patients with malignancy who underwent abdominopelvic surgery by a single surgeon (AWS). Lower extremity venous duplex scans (VDS) were performed preoperatively and before discharge. Demographics, procedures, and VTE outcomes were reviewed. The median age was 66 years. The average operative time was 315 minutes. All patients ambulated on postoperative day (POD) one or two. Epidural catheters (ECs) were removed on postoperative day four or five. No patient received VTE prophylaxis while an epidural catheter was in place. Preoperative lower extremity VDS revealed above-knee deep vein thrombosis (DVT) in seven patients (2.5%). Postoperative lower extremity VDS revealed acute DVT in 24 patients (8.4%): nine (3.2%) above-knee and 15 (5.2%) below-knee. The nine patients with above-knee DVT were anticoagulated after epidural removal. No patient developed a pulmonary embolism. Our data suggest that patients undergoing major open operations with epidural analgesia have low rates of DVT and may obviate the need for chemical prophylaxis. However, larger studies are required to determine the overall effects of epidural analgesia on the development of DVTs postoperatively.
Influence of Insurance Status on Hospital Length of Stay and Discharge Location in Burn Patients

Published: June 2020

Insurance status affects many aspects of healthcare in America, from access to delivery to outcomes. Our goal in this study was to determine whether different subtypes of insurance status affected hospital lengths of stay (LOS) and/or the location to which patients were discharged. The National Burn Repository was used to examine a total of 119,509 burn patients. Patients with noncommercial insurance (NONCOM) have increased LOS and are more likely to be discharged to a nonhome location, compared with no insurance or other insurance subtypes. Patients with no insurance have similar injury characteristics and comorbidities as patients with NONCOM, but have a shorter LOS and are more likely to be discharged home rather than to a skilled nursing facility or rehabilitation facility.

Published: June 2020

End-stage renal disease (ESRD) is a multifactorial disease linked to socioeconomic status and associated with worse surgical outcomes. We explore intraoperative and postoperative outcomes in patients with cholecystitis undergoing laparoscopic cholecystectomy (LC). The Nationwide Inpatient Sample from 2005 to 2012 was used to identify patients undergoing LC for cholecystitis using ICD-9 codes. Outcomes of interest were mortality, common bile duct injury, conversion to open, intraoperative complications, postoperative complications, length of stay (LOS), and total charge. Univariate analysis was performed using t test for continuous variables and chi-squared test for categorical variables. Multivariable models were created that adjusted for age, demographics, year of admission, comorbidities, and presence of ESRD. Of 225,058 patients that underwent LC, 2,115 had ESRD. On univariate analysis, the ESRD cohort had a higher incidence of mortality and complications: intraoperative, mechanical wound, respiratory, cardiovascular, and postoperative infections. ESRD patients had higher median LOS and total charge. Multi-variate analysis showed ESRD as an independent risk factor for mortality, mechanical wound complications, and intraoperative complications. Negative binomial regression analysis showed that ESRD patients had LOS 50.4 per cent longer than non-ESRD patients. Linear regression analysis showed that, after adjustment, ESRD patients had total charge 6.82 per cent higher than non-ESRD patients. In this large retrospective analysis, we find that after adjusting for clinical, socioeconomic, and demographic variables, ESRD is an independent risk factor for increased mortality, intraoperative complications, mechanical wound complications, increased LOS, and cost for patients undergoing LC. Prospective studies exploring risk optimization strategies for patients with ESRD are warranted.

Published: June 2020

A hiatal hernia (HH) is a frequent finding in patients with gastroesophageal reflux disease (GERD). We examined a consecutive series of patients with GERD diagnosed by a 24-hour pH monitoring. Based on the presence and size of HH on barium swallow, patients were divided into the following groups: no HH, HH <3 cm, HH 3–5 cm and HH >5 cm. A total of 175 patients were included: 43 with no HH, 86 with HH <3 cm, 34 with HH 3–5 cm, and 12 with HH >5 cm. Patients with larger HH had more frequent episodes of coughing and wheezing associated with episodes of reflux. High-resolution manometry showed that the increasing size of the HH was associated with decreasing pressure of the lower esophageal sphincter and weaker peristalsis. Ambulatory pH monitoring revealed that patients with larger HH had more acid reflux, in both the distal and proximal esophagus. Endoscopy showed that patients with larger HH had more severe esophagitis. Fifty per cent of patients with HH >5.0 cm had Barrett's esophagus. These findings should guide gastroenterologists and surgeons in choosing the appropriate therapy in patients with GERD and large HH.
Cost Analysis of Direct Oral Anticoagulants Compared with Warfarin in Patients with Blunt Traumatic Intracranial Hemorrhages
Authors: Lamb Laura C. , Difiori Monica , Comey Christopher , Feeney James
Published: June 2020

Direct oral anticoagulants (DOACs) are rapidly gaining popularity as alternatives to warfarin in the prevention of stroke or systemic embolic events because of the simplicity of their dosing and lack of monitoring requirement. Many physicians feared that these novel agents would be cost-prohibitive not only in their administration but also in their sequelae of bleeding, given the few reversal agents available. Whereas the medication itself is more expensive than traditional warfarin, the total cost of a hospital admission has not been compared between patients on DOACs and warfarin who have sustained a blunt traumatic intracranial hemorrhage (ICH). We conducted a retrospective review of our hospital's trauma database from June 2011 through September 2015 at our Level II trauma center of patients who suffered from an ICH who were anticoagulated at the time of their trauma. Patients who died during their hospital admission or were exclusively on antiplatelet agents were excluded. Of the 136 patients studied, 79 were on warfarin and 57 were on a DOAC at the time of their presentation for a traumatic ICH. The average charged cost for the hospital stay of a patient with an ICH was significantly higher for patients on warfarin compared with DOACs [$70,384.08 vs $49,226.66 (P = 0.02)]. The average reimbursement rate for the hospital was also significantly higher for those patients on warfarin as compared with those on DOACs [$23,922.93 vs $14,705.77 (P = 0.02)]. DOACs are associated with a significant cost benefit in patients admitted for blunt traumatic ICHs when compared with those on warfarin.

Acute surgical abdomen is commonly encountered in the ED and CT is widely used as an informative diagnostic tool to evaluate potential surgical indications. However, the adverse effects of contrast material used in CTscanning have been documented. We sought to delineate the role of noncontrast CT in the evaluation of patients with acute surgical abdomen. Between August 2015 and December 2015, patients with nontraumatic surgical abdomen who underwent preoperative CT were enrolled in the current study. The patients for whom the CT results permitted surgical decision-making were the focus of this study. The disease entities included acute appendicitis, acute cholecystitis, hollow organ perforation, mechanical bowel obstruction, intra-abdominal abscess that could not be drained percutaneously, and ischemic bowel disease. The results of contrast-enhanced and noncontrast CT were compared and analyzed. The surgical conditions identifiable by noncontrast CT were recorded. In total, 227 patients were enrolled in the study. In 90.7 per cent of patients overall, the findings indicating the need for surgical treatment were visualized on both the noncontrast and contrast-enhanced images (acute appendicitis: 89.3%, acute cholecystitis: 89.7%, hollow organ perforation: 97.4%, bowel obstruction: 100%, intra-abdominal abscess: 100%, and ischemic bowel disease: 55.6%). Noncontrast CT provides benefit for critical decision-making. Body mass index may affect the accuracy of noncontrast imaging in the evaluation of patients with surgical abdomen. In some specific situations, contrast enhancement remains necessary.

Published: June 2020

Presently, endoscopic procedures are a requirement for training competency for completion of a general surgery residency. There are no studies to date that have assessed whether having a resident perform a colonoscopy impacts quality indicators such as adenoma detection rate (ADR). To retrospectively review ADR in adult patients, who undergo screening colonoscopy at a single institution with (ColFacR) and without (ColFac) the participation of a general surgery resident. A total of 792 patients were identified in the database screening colonoscopies between the ages of 45 and 80 from July 2013 to June 2015. Of those, 501 were reviewed after exclusion criteria. When comparing the ColFac group (n = 316) to the ColFacR group (n = 185), there were no differences between age, gender, body mass index, American Society of Anesthesiologists score, or quality of bowel preparation. The mean number of total polyps, hyperplastic polyps, and adenomatous polyps retrieved were similar between the two groups. There was no difference in the ADR for the ColFac cases and ColFacR cases (25.95% vs 27.03%, respectively, P = 0.834). ADR is similar in elective colonoscopies that were performed with or without a general surgery resident. The participation of a general surgery resident in routine colonoscopies should not impact reported quality indicators.

Annually, approximately 70 million computed tomography (CT) scans are performed in emergency department (ED) settings in the United States of America. From 1995 to 2007, there has been a 5.9-fold increase in the use of CTscans nationally. The radiation risks and high costs associated with CTscans underscore the fact that the imaging modality, although necessary, carries a myriad of long-term risks to both patients and providers. For the workup of abdominal pain, most algorithms include the use of CTscan as an early step. To understand better the use of CTscans in our ED, we performed a retrospective review of patients presenting to the ED with abdominal pain. Two main questions were addressed: 1) what were the reasons for scans and how often did the scans reveal pathology related to the presenting symptoms, 2) how often were incidental findings identified. Our results showed that among patients presenting with abdominal pain to the ED, 50 per cent of the scans were normal, about 20 per cent of the patients had findings correlating with acute abdominal pain, whereas the rest (30%) had incidental findings that may have led to further outpatient studies or long standing abdominal pain. Most patients who presented to the ED had nonspecific abdominal pain i.e. 64.4 per cent. There was a low agreement between the presenting quadrant of pain and final pathological diagnosis (9.5–33.3% concordance), with left flank pain presentation having the highest level of agreement with the final pathologic diagnosis.

Enoxaparin regimens commonly used for prophylaxis fail to achieve optimal anti-factor Xa levels in up to 70 per cent of trauma patients. Accordingly, trauma services at the study institution endeavored to develop a standardized approach to optimize pharmacologic prevention with enoxaparin. An enoxaparin venous thromboembolism (VTE) prophylaxis protocol implemented in October 2015 provided weight-adjusted initial dosing parameters with subsequent dose titration to achieve targeted anti-factor Xa levels. Symptomatic VTE rate was evaluated 12 months pre- and post-implementation. Data were obtained from the trauma registry and charts were reviewed from electronic medical records. The rate of symptomatic VTE significantly declined post-implementation (2.0% vs 0.9%, P = 0.009). Enoxaparin use was comparable in these two phases validating that the decline in symptomatic VTEs was not due to an increase in enoxaparin use. Symptomatic VTE rate for patients who received enoxaparin in the post-implementation cohort decreased from 3.2 to 1.0 per cent (P = 0.023, 95% confidence interval = 0.124–0.856). There was also a significant decrease in the rate of symptomatic deep vein thrombosis (2.8% vs 0.9%, P = 0.040, 95% confidence interval = 0.117–0.950). This approach to VTE prophylaxis with enoxaparin resulted in a significant reduction in symptomatic VTE rates. Implementation of similar practices may be equally impactful in other institutions that use enoxaparin.
Improving Information Transfer during Transitions of Care via Standardized Handoffs

Published: June 2020

Multiple studies have shown the detrimental effect of miscommunication during transitions of care. The aim of this study is to determine whether a certain method of “sign-out” can improve information transmission and thereby reduce medical errors. Surgical interns underwent a 90-minute training session before starting residency in five previously verified methods of sign-out. They were randomly assigned to six groups (five methods and a control group). They were then given seven simulated patient charts with varying levels of medical complexity. They were then instructed to “sign-out” the patients to randomly selected colleagues. The control group did not use any of the previously taught methods and passed on information in a manner of their choosing. None of the methods consistently results in excellent transitions of care. Patient information values ranged from 26 to 40 (depending on complexity). Major points were consistently missed by all methods, but this may have been a component of the time constraint placed on this study. The “SIGNOUT?” method resulted in superior data transmission when compared with the control group (P = 0.0401). The only method that seemed to be significantly inferior was the “9Ds” method (P = 0.0610). The “SIGNOUT?” method leads to the largest amount of relevant information transmitted to the incoming team. There was no statistically significant difference among the other methods. Improvement in “sign-out” modalities and training may improve transmission of relevant patient information, but larger studies are needed to verify the data seen in this small, single-site study.

Geriatric trauma patients with low-level falls often have multiple comorbidities and limited physiologic reserve. Our aim was to investigate postdischarge mortality in this population. We hypothesized that five-year mortality would be higher relative to other blunt mechanisms. The registry of our Level 1 trauma center was queried for patients evaluated between July 2008 and December 2012. Adult patients identified were matched with mortality data from 2008 to 2013 from the National Death Index. Low-level falls were identified by E Codes; other types of blunt trauma were based on registry classification. Patients with multiple admissions were excluded. Univariate analysis was performed using Fisher's exact and Wilcoxon tests. Kaplan-Meier curves were plotted to compare postdischarge mortality. Seven thousand nine hundred sixteen patients were evaluated, 35.1 per cent were females. Patients aged less than 65 years and penetrating trauma were excluded, yielding 1997 patients—63.7 per cent with low-level falls versus 36.3 per cent with other blunt traumas. Geriatric patients sustaining low-level falls were older, more likely female, had a higher inpatient mortality, and were less likely to return home at discharge. Injury severity score, hospital length of stay, and intensive care unit length of stay were similar. Survival analysis demonstrated increased postdischarge mortality in the low-level fall group with 25 per cent mortality at 120 days. Geriatric patients with other blunt trauma had a significantly lower postdischarge mortality. Geriatric patients injured in low-level falls have a higher inhospital mortality, are more likely to be functionally dependent on discharge, and have a high post-discharge mortality. Opportunities likely exist for injury prevention, consideration of palliative care, and postdischarge rehabilitation.

In 2014, ACS-NSQIP® targeted pancreatectomies to improve outcome reporting and risk calculation related to pancreatectomy. At the same time, our department began prospectively collecting data for pancreatectomy in the Enhanced Recovery After Surgery® Interactive Audit System (EIAS). The purpose of this study is to compare reported outcomes between two major auditing databases for the same patients undergoing pancreatectomy. The same 171 patients were identified in both databases. Clinical outcomes were then obtained from each database and compared to determine whether reported complication rates were statistically different between auditing databases. A combination of Wilcoxon rank sum and Pearson's chi-squared tests were used to calculate statistical significance. No significant difference was appreciated in captured demographics between EIAS and NSQIP. Significant differences in reported rates for renal dysfunction, postoperative pancreatic fistula, return to the operative room, and urinary tract infection were noted between EIAS and NSQIP. Although significant differences in reported complication rates were demonstrated between EIAS and NSQIP for pancreatectomy, much of the discrepancy is attributable to subtle differences in definitions for postoperative occurrences between the two auditing databases. It is vital for surgeons to understand the exact definition that determines the complication rate for a given database.

Published: June 2020

The purpose of this study was to assess resource utilization after implementation of a mild traumatic brain injury (TBI) treatment protocol. A retrospective review was conducted of patients with isolated mild TBI before and after implementation of a mild TBI treatment protocol in May 2015. Patients admitted from June 2014 to February 2017, aged 18 to 89 years, presenting with a Glasgow coma score of 13 to 15, with an isolated small intracerebral hemorrhage on CT without midline shift, and not coagulopathic were evaluated. According to the protocol, patients were admitted to a non-intensive care unit (ICU) ward, without routine neurosurgical consultation or repeat head CT unless clinically indicated. Hospital length of stay (LOS), ICU LOS, rate of neurosurgical consultation, rate of repeat head CT within 24 hours of admission, and associated costs were evaluated. Forty-six patients were identified in the preprotocol group and 97 in the protocol group. The protocol group had a shorter hospital LOS (1.46 vs 2.04 days, P = 0.0034), shorter ICU LOS (0.02 vs 0.37 days, P < 0.0001), lower rates of repeat head CT (2.06% vs 39.13%, P < 0.0001), and neurosurgical consultations (1.03% vs 28.26%, P < 0.0001). Decreased charges derived from fewer repeat head CT and neurosurgical consultations were observed from $43.98 to $844.04 per patient. There were no inpatient mortalities and no progressions of injury requiring unplanned admission to the ICU or operative intervention. Efficient delivery of care is paramount in modern medicine and this study demonstrates that the mild TBI treatment protocol significantly decreased resource utilization without jeopardizing patient safety.

In 2015, the United States Navy hospital ship (USNS) COMFORT, deployed to 11 Caribbean and Latin American countries over a six-month period to provide humanitarian civic assistance. Personnel from the United States Navy and multiple nongovernmental organizations collaborated to offer surgical and medical care. Data from past deployments aid in planning for future missions by prioritizing finite resources and maximizing care. The data analyzed included all patients evaluated and treated by the Directorate of Surgical Services of the USNS COMFORT between April and September 2015. Comparative and descriptive statistics were performed to analyze patient demographics, surgical subspecialty performing the procedures, types of general and pediatric surgical procedures performed, operative times, and complication rates. Of the 1256 surgical cases performed aboard USNS COMFORT during CP15, 24.8 per cent were general surgery cases, followed by 16 per cent ophthalmology, 10.6 per cent pediatric surgery, 10 per cent plastic surgery, and eight additional specialties with <10 per cent of the cases each. Total operative time was 1253 hours with a total room time of 1896.5 hours. The identified complication rate was 1.99 per cent across all specialties. The USNS COMFORT platform offers the unique capability to provide humanitarian surgical assistance. Reporting these data demonstrate that there is a need for humanitarian assistance and this can be provided safely through the Continuing Promise mission. Future deployments may target resources toward the surgical services with higher volumes, which were general surgery, ophthalmology, pediatric surgery, and plastic surgery.

Identifying disparities in surgical outcomes among patient populations may help hospitals target patients at highest risk for complications. The South Carolina Surgical Quality Collaborative (SCSQC) is a regional collaborative made up of eight facilities whose goal is to improve the quality and value of general surgical care in South Carolina. Using SCSQC data, we reviewed colon surgery outcomes to determine whether disparities exist between specific patient populations. SCSQC colon surgery data were reviewed from August 2015 to August 2017. SSI, length of stay, return to the ED, and reoperation rates were used as outcome measures. They were evaluated in patient populations stratified by gender, race (white, black, and other), and age (<50, 50–70, and >70 years). A total of 2611 patients were included in this study. Statistically significant differences in outcomes were identified between white and black patients in length of stay (6.0 vs 7.5 days, P < 0.0001) and return to the ED (8.1% vs 14.7%, P < 0.0001), but not in SSI (6.4% vs 6.8%, P = 0.8839) or reoperation rates (6.4% vs 8.4%, P = 0.1886). Length of stay increased with increasing age (4.1 vs 7.1 vs 8.8, P < 0.0001). SSI varied by age (4.0% vs 8.2% vs 6.4%, P = 0.0005), as did return to the ED (11.2% vs 9.7% vs 769%, P = 0.0987) and reoperation rates (4.5% vs 8.1% vs 8.2%, P = 0.0034). SCSQC data indicate that race and age may place patients at risk for negative outcomes after colorectal surgery.

Health care consumers are burdened with rising out-of-pocket medical expenses. Surgical specialists’ experience and attitude towards patients’ out-of-pocket costs and the influence of these factors on healthcare utilization are unknown. Our aim was to define the pediatric surgeons’ experience with the financial concerns of their patients. Members from the American Academy of Pediatrics Sections on Plastic Surgery, Surgery and Urology were surveyed. Analysis of variance was used to investigate practice differences. Two hundred and eighteen out of 973 surgeons representing 38 states completed the survey. Nearly half of the surveyed surgeons did not know if cost was a determinant for their patients’ choice in surgical facility, or if parents compared costs prior to the visit. Eighty four per cent of the surgeons would consider patient costs if medically appropriate, to entertain less costly alternatives, and adjust surgical scheduling to decrease economic burden. Most pediatric surgical specialists are unaware if out-of-pocket costs influenced patients’ preoperative decisions. Nonetheless, they are sympathetic to the issue. As the financial burden of health care shifts to consumers, our survey indicates that surgeons are open to candid discussion surrounding finances and may alter recommendations accordingly if appropriate.

The surgical community has expressed concern that residents do not receive the same caliber training as their predecessors and the increase in fellowships have been described as secondary to perceived lack of preparation. Yet, data show no change in total cases even after implementation of the 80-hour workweek. It is hypothesized that the increasing subspecialization of general surgery may decrease in certain resident case numbers. Data were collected from the Accreditation Council for Graduate Medical Education (ACGME) General Surgery Case Logs National Data Report (1999–2014) of mean number of procedures per resident for 19 surgical categories. Statistical analysis was performed with analysis of variance over three time periods between 1999 and 2014. The number of total cases performed by residents has not changed significantly. There was a statistically significant difference observed in the variety of cases: vascular, esophageal, breast, and trauma cases decreased (P < 0.01), whereas major intestinal, hernia, liver, pancreatic, and biliary cases increased (P < 0.01). There are many reasons to pursue additional training after residency. The demonstrated change in case variability, presumably secondary to increasing fellowships, may play a significant role on training and preparation. Close monitoring of curriculums is essential to ensure a comprehensive general surgical education.

This study queried American Society of Colon and Rectal Surgeons members for management of sigmoid volvulus and aimed to determine whether surgeon experience impacts decision-making. American Society of Colon and Rectal Surgeons members received a 16-item survey in March, 2017. Items included endoscopic detorsion technique and colonic decompression, preoperative dietary considerations, surgical approach, and respondents’ demographics. Respondents were separated into low experience (LE; ≤10 years in practice) and high experience (HE; >10 years in practice). Of 1996 survey recipients, 10 per cent (197) responded; 124 were HE and 73 were LE. Most were fellowship-trained (93.8%) and primarily in colorectal surgery practice (74.6%), however only 27.4 per cent managed >20 sigmoid volvulus cases as attendings. Fifty-two per cent use rectal tubes for continued colonic decompression after successful endoscopic detorsion; 81.2 per cent would perform sigmoid colectomy on the index admission after successful detorsion, but within a variable timeframe (one to seven days postdetorsion) and with variable dietary restrictions in the interval period; 49.7 per cent would perform a laparoscopic colectomy and 68.3 per cent would perform a stapled colorectal anastomosis. LE surgeons reported a higher proportion of gastrointestinal-performed endoscopic detorsions (P = 0.015), were more likely allow regular diet in the interval period (P = 0.031), and were more inclined to use laparoscopy (P = 0.008), versus HE surgeons. There remains controversy among many of the components in the management of sigmoid volvulus after successful endoscopic detorsion.

Although the mental workload confronted by laparoscopic surgeons is rather high, there is presently no reliable, established method for evaluating this workload. In the present study, four evaluation indices of eye movement metrics were applied to evaluate surgeons’ mental workload. Correlations between these indices and National Aeronautics and Space Administration Task Load Index (NASA-TLX) scores were also explored. Sixteen participants were recruited to complete four laparoscopic procedures. Eye movement was recorded during the tasks, and NASA-TLX scales were also introduced for subjective evaluation. The data were analyzed using R 3.3.2. Significant differences in the mental workload of each task were observed. Statistically significant correlations between mean pupil diameter change and NASA-TLX scores were also observed. The correlation coefficients were 0.763, 0.675, 0.405, and 0.547, and the P values correspondingly were 0.001, 0.004, 0.12, and 0.028, respectively. The results clarify that the mental workload of laparoscopic surgeons is dependent on the specific demands of the operation. Appropriate objective physiological indices can be used to identify the mental workload state of the surgeon.

Accurate preoperative clinical staging is essential to optimize the treatment of rectal cancer. Primary surgical resection is typically indicated for stage I disease, whereas neoadjuvant therapy is recommended for stages II and III. The objective of this study is to examine the accuracy of clinical staging using current imaging modalities in predicting pathologic stage and, thus, selecting appropriate treatment. Adult patients with nonmetastatic rectal cancer who underwent primary surgical resection were identified from the National Cancer Database between 2006 and 2014. Data on clinical and pathologic staging was obtained. Kappa index was used to determine the correlation between clinical and pathologic staging. A total of 13,175 patients were identified. The correlation between clinical and pathologic staging was 69 per cent for stage I (31% upstaged) (Kappa 0.54, P < 0.001). One-third of patients who were clinically staged as stage I, and were therefore treated with primary surgical resection, had pathologic stage II or III disease. Based on their clinical staging, those patients did not receive the neoadjuvant therapy recommended by present guidelines. Where accurate clinical staging is in doubt, oncologists should carefully examine the quality of staging modality and perhaps consider multimodal imaging using both endorectal ultrasound and MRI.

Right-side diverticulitis (RSD) is an uncommon disease in Western countries. We conducted a case-matched comparison of surgically managed right-side and left-side diverticulitis (LSD) from the Southern California Kaiser Permanente database (2007–2014). Of 995 patients undergoing emergent surgery for diverticulitis, 33 RSD (3.3%) met our inclusion criteria and were matched (1:1) to LSD based on age, gender, year of diagnosis, and Hinchey class. Mean age of the RSD group was 56 ± 13.9 years, and 24.2 per cent were Asian. RSD was classified as Hinchey class III or IV in 28.1 per cent and 9.4 per cent of cases, respectively. Right hemicolectomy was performed in 87.9 per cent and laparoscopy was used in 24.2 per cent of the cases. Surgically managed RSD patients were more likely to be Asian (25% vs 3.1%, P = 0.03) and have body mass index < 25 (31.3% vs 6.3%, P = 0.02) compared with LSD patients. Diverting stoma was less common in the RSD (6.3% vs 62.5%) ( P < 0.001). Hospital stay was shorter in RSD (7.6 ± 4.2 vs 12.8 ± 9.4 days, P = 0.006) and more common in the RSD group ( P < 0.01). Open surgery (90.6% vs 71.9%) and postoperative complications (37.5% vs 25%) were more common in the LSD group, but that was not statistically significant ( P > 0.05). Surgery for complicated RSD was associated with shorter hospital stay and decreased likelihood of diverting ostomy.
