RESUMO
Bear attacks, although rare, can inflict life-threatening injuries. We present the case of a 50-y-old woman from rural Pennsylvania who was attacked by a North American black bear, Ursus americanus. She sustained multiple complex injuries including near-complete scalp avulsion, bilateral ear avulsions, and fractures of the face, ribs, and pelvis. These injuries are similar to those sustained in other bear maulings reported in the literature and required both acute intervention and a multidisciplinary approach to recovery.

BACKGROUND: The aim of this study was to evaluate the influence of sex on facultys' perception of resident autonomy and performance. METHODS: Autonomy/performance/complexity evaluations performed by faculty of categorical general surgery residents (2015-2021) were analyzed. Comparisons of scores by faculty and resident sex were performed. RESULTS: A total of 10967 paper/electronic evaluations were collected. Female attendings rated female residents significantly lower in autonomy when compared to males (2.75 vs 2.91, p â= â0.0037). There was no significant difference in autonomy ratings for male versus female residents when evaluated by a male attending (2.93 vs 2.96, p â= â0.054) but male attendings did rate female residents significantly lower in autonomy at the highest complexities (2.37 vs 2.50, p â= â0.012). CONCLUSION: The data suggests a unique interaction between attending and resident sex. A periodic evaluation of evaluations within one's program may provide invaluable implicit bias insight and should be considered.

Multiple gastrointestinal stromal tumors (GISTs) of the small intestine is an uncommon finding but can be a marker for underlying neurofibromatosis type 1 (NF1). We present the case of the 38-year-old male without prior NF1 diagnosis who presented with a small bowel obstruction. His physical exam was notable for cutaneous nodules and café-au-lait spots. He progressed to peritonitis and underwent an exploratory laparotomy, which revealed a 6-cm hemorrhagic mass along the antimesenteric border of the jejunum, causing obstruction and perforation. Pathology was consistent with GISTs. NF1-associated GISTs differ from wild-type GISTs in that they are unlikely to have C-KIT and PDGFRA mutations and therefore do not respond to imatinib. Treatment is largely limited to surgical resection; however, there is evidence that MEK inhibitors may prove an additional treatment strategy.

INTRODUCTION: Over the past decade, small bowel obstructions (SBO) have been increasingly managed non-operatively. Prior studies have looked at outcomes based on admission to surgical services (SS) or medicine services (MS), but most are restricted to operative patients. This study evaluates the outcomes of non-operative patients specifically. METHODS: A 12-year retrospective cohort study of patients ≥18-years-old admitted with SBO within one healthcare system was performed. Only non-operative patients were included. Clinicodemographic characteristics and admission details were extracted from the electronic medical record. Statistical analysis was performed using the student's t-test, chi-square, and multivariable regression. RESULTS: A total of 3278 patients were included, of which 933(28.4%) patients were admitted to a SS. MS patients were older (57.7 vs 54.7 years, P < .001) and more likely to have diabetes (24.1 vs 20.2%, P = .015), CHF (5.7 vs 3.1%, P = .002), and AKI (29.8 vs 16.7%, P < .001). SS patients were more likely to have cancer (19.3 vs 13.7%, P < .001). Univariate analysis showed admission to SS decreased length of stay (3.4 vs 4.1 days, P < .001) and index admission mortality (0.1 vs 2.2%, P < .001). On multivariable analysis, admission to a SS decreased admission mortality (OR 0.056), 30-day mortality (OR 0.15), and 180-day mortality (OR 0.307). Similarly, 30-day readmissions (OR 0.683) and 180-day readmission (OR 0.54) were also significantly decreased. Length of stay was decreased by .6 days (P < .001). DISCUSSION: In patients with non-operative SBO, admission to a surgical service decreased length of stay, mortality, and readmission. Further work should be completed evaluating how increased comorbidities affect long term outcomes. However, significantly decreased length of stay and mortality continue to support surgical services admitting SBO patients.

INTRODUCTION: Small bowel obstruction (SBO) is a common admission diagnosis. Prior research has shown improved length of stay and time to operation for SBO patients on surgical services (SS) compared to medical services (MS). This study evaluates the impact of admitting service on readmission and mortality. METHODS: A 12-year retrospective cohort study of patients ≥18 years old, admitted with SBO to either a MS or SS within one health care system was performed. Clinicodemographic characteristics and admission details were extracted and reviewed. Statistical analyses performed included the Student's t-test, chi-square, and multivariable regression. RESULTS: The study included 7921 patients, of which 3862 (48.8%) were admitted to a SS. No significant clinicodemographic differences existed between the groups except SS patients were more likely to have cancer (23.3% vs 15.2%, P < .0001) and to be within a 30-day post-operative period (9.4% vs 1.8%, P < .0001). On multivariable analysis, admission to a SS was associated with a decreased admission mortality (OR .70), 30-day mortality (OR .42), and 180-day mortality (OR .42). 30-day readmissions (OR .54) and 180-day readmission (OR .43) were also significantly decreased for SS patients. In patients requiring a procedure during admission, there was significantly decreased admission mortality (OR .684), 30-day mortality (OR .470), 180-day mortality (OR .431), 30-day readmission (OR .63), and 180-day readmission (OR .50). CONCLUSION: In patients with SBO, admission to a SS confers decreased odds of readmission and mortality compared to MS. Future studies are needed to understand the management decisions potentially underlying these differences. These findings may help better define admission pathways and improve outcomes.

BACKGROUND: Acute kidney injury (AKI) is a known postoperative complication of open ventral hernia repair contributing to increased costs, hospital length of stay, and mortality. The aim of this study was to identify whether the muscle injury that occurs in a posterior separation of components via transversus abdominis release (TAR) contributes to a higher incidence of postoperative AKI. METHODS: A retrospective cohort study of patients who underwent open retrorectus ventral hernia repair with and without TAR at a single institution between 2012 and 2019 was performed. Patients who underwent a separation of components via either unilateral or bilateral transversus abdominis release were compared to those who did not undergo TAR as part of their hernia repair (non-TAR). The outcome of interest was the development of postoperative AKI. Acute kidney injury was defined as an increase in creatinine of greater than 50% of the preoperative baseline. Univariate and multivariate analyses were performed to determine the influence of TAR on the development of AKI. RESULTS: There were 523 patients who met inclusion criteria, of which 159 (30.4%) had a TAR as part of their retrorectus hernia repair. No differences were found in preoperative characteristics between the TAR and non-TAR group including age, gender, history of kidney disease, or history of diabetes. By contrast, the TAR group had significantly greater median estimated blood loss (100 mL vs 75 mL, P < .01), mean positive intraoperative fluid balance (2255 mL vs 1887 mL, P < .01), and operative duration (321 min vs 269 min, P < .001). The rate of AKI in the TAR group was 11% (n = 18) vs 6% (n = 23, P = .0503) in the non-TAR group. On multivariate analysis controlling for patient characteristics and intraoperative factors, TAR was the only factor with a significantly increased odds of AKI (OR 1.97, 95% CI 0.994-3.905, P = .0521). CONCLUSIONS: In patients with large ventral hernias requiring retrorectus repair, performing a TAR is associated with a nearly 2-fold increase in the development of postoperative AKI. These findings suggest that these patients should be optimized perioperatively with emphasis on fluid resuscitation, limiting nephrotoxic medications and monitoring urine output.

BACKGROUND: Abdominal wall hernias continue to be one of the most common general surgery pathologies. Patients with an elevated body mass index (BMI) are routinely counseled about weight loss before elective repair. However, a definitive BMI "cutoff" has not been established. Here, we report our experience with open retro-rectus hernia repair (ORRHR) with mesh in patients with a BMI over 40 kg/m2, and we attempt to determine if a BMI "cutoff" can be established. METHODS: Data from patients undergoing ORRHR with mesh at Geisinger Medical Center from January 1, 2014, to December 31, 2018, were collected and retrospectively analyzed. RESULTS: Cohorts were composed of 2 groups, BMI ≥ 40 kg/m2 (n = 117) and BMI < 40 kg/m2 (n = 90). All patients underwent an elective ORRHR with mesh. Operative time increased significantly as the patient's BMI increased (P ≤ .01). Patients in the higher BMI group had a significantly higher rate of surgical site infections (SSIs) (8.55% vs. 1.1%, P = .018). Higher BMI did not translate to a higher recurrence rate. CONCLUSIONS: Patients undergoing ORRHR with mesh who had a BMI over 40 kg/m2 had an increased risk of SSI and longer operative time, possibly suggesting a potential association other than SSI and BMI. More studies are needed to determine if BMI is indeed correlated with hernia recurrence and if BMI should influence the decision to undergo repair.

Pancreatic necrosis can be managed conservatively; however, infection of pancreatic necrosis usually dictates more aggressive management. Our study aimed to assess the outcomes of open pancreatic necrosectomy (OPN) and endoscopic pancreatic necrosectomy (EPN) in a single center. Data from patients undergoing pancreatic necrosectomy at the Geisinger Medical Center from January 1, 2007, to April 25, 2016, were collected and retrospectively analyzed. Cohorts were composed of EPN (n = 22) and OPN (n = 34) groups. The prevalence of preoperative respiratory failure, septic shock, and multiorgan dysfunction syndrome was higher in the OPN group. The OPN group presented with a higher Bedside Index Severity in Acute Pancreatitis score. Postoperative abscess, persistent kidney dysfunction, and death were more frequent in the OPN group. The EPN group had a higher readmission rate. The results of the univariate analysis for complication and mortality demonstrated that higher mortality and persistent kidney dysfunction were associated with the procedure type, specifically OPN and with a higher Bedside Index Severity in Acute Pancreatitis score. Patients who presented with higher severity of disease underwent an OPN, whereas EPN often was performed successfully in a more benign clinical setting. However, patients with infected necrosis are served best in a tertiary medical facility where multiple treatment modalities are available.

BACKGROUND: From 1990-2005 at Ochsner Medical Center in New Orleans, LA, cardiopulmonary bypass (CPB) was used only when necessary during lung transplantation surgeries. Ochsner's lung transplant program was closed for more than 4 years after Hurricane Katrina, and since the program's reestablishment in 2010, the majority of lung transplantation surgeries have been performed with the patient on CPB and with a median sternotomy incision. The purpose of this study was to compare the outcomes of the CPB and non-CPB groups. METHODS: After institutional review board approval, we conducted a retrospective review of the entire program using the Ochsner lung transplant database to identify patients in the non-CPB group from 1990-2005 and in the CPB group from 2010-2014. We calculated 1- and 3-year survival rates for each patient and reviewed medical records for evidence of stroke, the need for operative reexploration, and venous stenosis. We also performed a subgroup analysis of the first 20 consecutive patients undergoing lung transplantation on CPB with median sternotomy from February 2010 through April 2011 to examine intraoperative blood product use, the quantity of blood products administered, CPB cannulation and pump complications, ischemic time, and primary graft dysfunction. RESULTS: Of the 208 patients in the non-CPB group, 74% had 1-year graft survival and 55% had 3-year survival following transplantation. After February 2010, 79 patients underwent lung transplantation on CPB with median sternotomy, and 90% of those patients had 1-year graft survival. Of the 46 patients available for 3-year follow-up, 59% were alive with functional grafts. The difference in 1-year survival rates between the 2 cohorts was statistically significant. Two deaths, 3 strokes, and 5 reexplorations of the chest for bleeding occurred during the perioperative time period in the CPB group, but no mortality was associated with these perioperative events. One patient who had perioperative complications died within the first year; the death was attributable to gastric perforation. CONCLUSION: Patients' early outcomes appear to have improved with the use of CPB and median sternotomy; however, 3-year survival is similar to the non-CPB group. Technical benefits of CPB with median sternotomy include decreased warm ischemia time during graft implantation, controlled hemodynamics and reperfusion, avoidance of single-lung ventilation of a freshly implanted graft, and the option to open the left atrium for implantation of a venous cuff without using a clamp. The surgical exposure facilitated by CPB with median sternotomy for lung transplantation appears to be a safe and feasible approach for lung transplantations.
