American Board of Surgery In-Training Examination (ABSITE) performance has become an important factor when monitoring resident progress. Understanding which prospective factors predict performance can help identify residents at risk.

A literature search was conducted searching PubMed, EMBASE, and JAMA Network from June 2011 to June 2021, in accordance with the PRISMA guidelines. Searches were performed for the terms “ABSITE” and “American Board of Surgery In-Training Examination.” Prospective factors such as prior examination performance, clinical evaluations, and demographics were evaluated.

A final 35 studies were included. The prospective factor most consistently found to predict ABSITE performance is performance on prior knowledge-based examinations such as the USMLE step exams. The ACGME Medical Knowledge 1 milestone evaluation also appears to correlate to ABSITE performance, although clinical evaluations, in general, do not. Demographics have no significant correlation to ABSITE performance.

Using performance on prior knowledge-based examinations programs may be able to identify residents at risk for failing ABSITE. It may be possible to initiate early intervention before rather than only remediation after poor performance.

There are limited studies regarding the impact of post-operative leak on perforated peptic ulcer disease (PPUD) and conflicting results regarding routine drain placement in operative repair of PPUD. This study aims to identify risk factors for gastrointestinal leak after operative repair of PPUD to better guide intra-operative decisions about drain placement.

We performed a retrospective cohort study at a tertiary care center from 2008 to 2019, identifying 175 patients who underwent operative repair of PPUD.

Patients who developed a leak (17%) were compared to patients who did not. Both hypoalbuminemia (albumin < 3.5 g/dL) (P = .03) and duodenal ulcers (P < .01) were identified as significant risk factors for leak. No significant difference was found between leak and no leak groups for AAST disease severity grade, repair technique, or pre-operative use of tobacco, alcohol, or steroids. Post-operative leaks were associated with prolonged hospital stay (29 days compared to 10, P < .01), increased complication rates (77% compared to 48%, P < .01), and increased re-operation rates (73% compared to 26%, <0.01). No difference was identified in patient characteristics or operative leak rates between patients who had drains placed at the index operation and those that did not.

Leak after operative PPUD repair is associated with significant post-operative morbidity. Hypoalbuminemia and duodenal perforations are significant risk factors for post-operative leaks.

Restrictive pulmonary dysfunction (RPD) is a risk factor for perioperative complications during gastrointestinal surgery. We hypothesized that high airway pressure due to RPD results in increased intraoperative blood loss during liver surgery. Thus, we investigated the effects of RPD on perioperative outcomes for liver resection.

This study included 496 patients who underwent curative liver resection at our hospital between April 2009 and April 2020. Perioperative outcomes for the RPD and control groups were compared. Restrictive pulmonary dysfunction was defined as % vital capacity <80%.

Forty-one patients (8.3%) had RPD. No significant differences were observed in intraoperative blood losses (440 mL vs 320 mL, P = .340), overall complication rates (29.3% vs 31.2%, P = .797), or pulmonary complication rates (4.9% vs 9.0%, P = .286) between the RPD and control groups. In the 256 patients who underwent anatomical liver resection, 18 patients (7.0%) had RPD. The intraoperative blood loss was significantly higher in the RPD group (925 mL vs 456 mL, P = .013), but no differences in the overall complication rates (44.4% vs 37.3%, P = .528) or pulmonary complication rates (11.1% vs 10.5%, P = .589) between the two groups were detected. A multivariate analysis showed that RPD was an independent risk factor for intraoperative blood loss ≥500 mL during anatomical liver resection (odds ratio 4.132; 95% confidence interval 1.135-15.045; P = .031).

Restrictive pulmonary dysfunction may be a risk factor for intraoperative blood loss during anatomical liver resection, which requires exposure of the main hepatic vein.

COVID-19 is a deadly multisystemic disease, and bowel ischemia, the most consequential gastrointestinal manifestation, remains poorly described. Our goal is to describe our institution’s surgical experience with management of bowel ischemia due to COVID-19 infection over a one-year period.

All patients admitted to our institution between March 2020 and March 2021 for treatment of COVID-19 infection and who underwent exploratory laparotomy with intra-operative confirmation of bowel ischemia were included. Data from the medical records were analyzed.

Twenty patients were included. Eighty percent had a new or increasing vasopressor requirement, 70% had abdominal distension, and 50% had increased gastric residuals. Intra-operatively, ischemia affected the large bowel in 80% of cases, the small bowel in 60%, and both in 40%. Sixty five percent had an initial damage control laparotomy. Most of the resected bowel specimens had a characteristic appearance at the time of surgery, with a yellow discoloration, small areas of antimesenteric necrosis, and very sharp borders. Histologically, the bowel specimens frequently have fibrin thrombi in the small submucosal and mucosal blood vessels in areas of mucosal necrosis. Overall mortality in this cohort was 33%. Forty percent of patients had a thromboembolic complication overall with 88% of these developing a thromboembolic phenomenon despite being on prophylactic pre-operative anticoagulation.

Bowel ischemia is a potentially lethal complication of COVID-19 infection with typical gross and histologic characteristics. Suspicious clinical features that should trigger surgical evaluation include a new or increasing vasopressor requirement, abdominal distension, and intolerance of gastric feeds.

Little is known regarding the impact of operating room (OR) personnel generation on their perceptions to various surgeon behaviors. We aimed to characterize these relationships by evaluating their responses to 5 realistic intraoperative scenarios.

Operating room personnel were asked to assess surgeon OR behavior across a standardized set of 5 scenarios via an online survey. For each scenario, respondents were asked to identify the behavior as either acceptable, unacceptable but would ignore, unacceptable and would confront the surgeon, or unacceptable and would report to management. Chi-squared analyses were used to compare responses to surgeon behavior with respondent generation.

There were 3101 respondents, of which 41% of respondents were baby boomers (n = 1280), 31% were generation (Gen) X (n = 955), and 28% were Gen Y (n = 866). Overall, when compared to Gen X or Gen Y, baby boomers were significantly more likely to find surgeon behaviors of impatience (P < .001), being late for a case (P < .001), swearing in the OR (P < .001), and shouting with a bleeding patient (P = .001) to be inappropriate and would talk to the surgeon. Alternatively, Gen Y respondents were more likely to find fault with surgeon behaviors that deviate from rules and regulations, such as forgetting a time-out (P = .001), when compared to baby boomers and Gen X respondents.

Results of our study demonstrate that OR personnel generation affects their perceptions and response to surgeon behavior. Understanding these tendencies can guide efforts to improve OR interactions among team members.
