OBJECTIVE: The aim of this study was to investigate the volume-outcome relationship in kidney transplantation by examining graft and patient outcomes using standardized risk adjustment (observed-to-expected outcomes). A secondary objective was to examine the geographic proximity of low, medium, and high-volume kidney transplant centers in the United States. SUMMARY OF BACKGROUND DATA: The significant survival benefit of kidney transplantation in the context of a severe shortage of donor organs mandates strategies to optimize outcomes...

OBJECTIVE: National examination of open proctectomy (OP), laparoscopic proctectomy (LP), and robotic proctectomy (RP) in pathological outcomes and overall survival (OS). BACKGROUND: Surgical management for rectal adenocarcinoma is evolving towards utilization of LP and RP. However, the oncological impacts of a minimally invasive approach to rectal cancer have yet to be defined. METHODS: Retrospective review of the National Cancer Database identified patients with nonmetastatic locally advanced rectal adenocarcinoma from 2010 to 2014, who underwent neoadjuvant chemoradiation, surgical resection, and adjuvant therapy...

OBJECTIVE: To trend fibrinolysis after injury and determine the influence of traumatic brain injury (TBI) and massive transfusion on fibrinolysis status. BACKGROUND: Admission fibrinolytic derangement is common in injured children and adults, and is associated with poor outcome. No studies examine fibrinolysis days after injury. METHODS: Prospective study of severely injured children at a level 1 pediatric trauma center. Rapid thromboelastography was obtained on admission and daily for up to 7 days...

OBJECTIVE: To determine rates of axillary dissection (ALND) and nodal recurrence in patients eligible for ACOSOG Z0011. BACKGROUND: Z0011 demonstrated that patients with cT1-2N0 breast cancers and 1 to 2 involved sentinel lymph nodes (SLNs) having breast-conserving therapy had no difference in locoregional recurrence or survival after SLN biopsy alone or ALND. The generalizability of the results and importance of nodal radiotherapy (RT) is unclear. METHODS: Patients eligible for Z0011 had SLN biopsy alone...

OBJECTIVE: This study aims to validate a previously reported recurrence clinical risk score (CRS). SUMMARY OF BACKGROUND DATA: Salvage transplantation after hepatocellular carcinoma (HCC) resection is limited to patients who recur within Milan criteria (MC). Predicting recurrence patterns may guide treatment recommendations. METHODS: An international, multicenter cohort of R0 resected HCC patients were categorized by MC status at presentation...

OBJECTIVE: We hypothesized that low molecular weight heparin (LMWH) is superior to unfractionated heparin (UH) for venous thromboembolism (VTE) prophylaxis in patients with severe traumatic brain injuries (TBI). SUMMARY BACKGROUND DATA: Pharmacological VTE prophylaxis with LMWH or UH is the current standard of care in TBI. Clinical work suggests that LMWH may be more effective than UH for VTE prophylaxis in trauma patients. Experimental work shows that heparinoids may have neuroprotective properties...

OBJECTIVE: We sought to develop and evaluate a video-based coaching program for board-eligible/certified surgeons. SUMMARY BACKGROUND DATA: Multiple disciplines utilize coaching for continuous professional development; however, coaching is not routinely employed for practicing surgeons. METHODS: Peer-nominated surgeons were trained as coaches then paired with participant surgeons. After setting goals, each coaching pair reviewed video-recorded operations performed by the participating surgeon...

OBJECTIVE: To determine whether concurrently performed operations are associated with an increased risk for adverse events. BACKGROUND: Concurrent operations occur when a surgeon is simultaneously responsible for critical portions of 2 or more operations. How this practice affects patient outcomes is unknown. METHODS: Using American College of Surgeons' National Surgical Quality Improvement Program data from 2014 to 2015, operations were considered concurrent if they overlapped by ≥60 minutes or in their entirety...

OBJECTIVE: The primary purpose of this study was to assess risk factors for delirium in patients staying in a surgical ward for more than 5 days. The secondary purpose was to assess outcomes in patients with delirium. BACKGROUND: Delirium is a syndrome characterized by acute fluctuations in mental status. Patients with delirium are at increased risk of adverse inpatient events, higher mortality and morbidity rates, prolonged hospital stays, and increased health care costs...

OBJECTIVE: The aim of this study was to evaluate the utility of the P4 stump stenting approach for treating portal vein (PV) complications in pediatric living donor liver transplantation (LDLT). BACKGROUND: PV complications cause significant morbidity and mortality in pediatric LDLT. Biliary atresia in the backdrop of pathological PV hypoplasia and sclerosis heightens the complexity of PV reconstruction. The authors developed a novel approach for intraoperative PV stenting via the graft segment 4 PV stump (P4 stump) to address this challenge...

OBJECTIVE: Our aim was to assess the short-term impact of centralization on the outcomes of patients undergoing abdominal aortic aneurysm repair in a vascular network in the South West of England. BACKGROUND: The centralization of vascular services has been implemented nationally across the National Health Service to improve patient outcomes. The full impact of these major changes has not yet been fully analyzed. METHODS: A retrospective cohort study examining outcomes of patients undergoing abdominal aortic aneurysm repair, based on prospectively entered National Vascular Registry data, pre and post centralization in the South West of England...

BACKGROUND: Laparoscopic surgery for rectal cancer is widely performed all over the world and several randomized controlled trials have been reported. However, the usefulness of laparoscopic surgery compared with open surgery has not been demonstrated sufficiently, especially for the low rectal area. OBJECTIVE: The aim of this study was to investigate the hypothesis that laparoscopic primary tumor resection is safe and effective when compared with the open approach for locally advanced low rectal cancer...

OBJECTIVE: To evaluate the relationship between donor sex and hepatocellular carcinoma (HCC) recurrence after living donor liver transplantation. BACKGROUND: HCC shows a male predominance in incidence and recurrence after tumor resection due to sex differences in hepatic sex hormone receptors. There have been no studies evaluating the importance of donor sex on post-transplant HCC recurrence. METHODS: Of 384 recipients of livers, from living donors, for HCC: 104/120 who received grafts from female donors were matched with 246/264 who received grafts from male donors using propensity score matching, with an unfixed matching ratio based on factors like tumor biology...

OBJECTIVE: To discern recurrence risk stratification and investigate its influence on postoperative surveillance in patients with esophageal adenocarcinoma (EAC) after neoadjuvant chemoradiotherapy (CRT). BACKGROUND: Reports documenting recurrence risk stratification in EAC after neoadjuvant CRT are scarce. METHODS: Between 1998 and 2014, 601 patients with EAC who underwent neoadjuvant CRT followed by esophagectomy were included for analysis...

: Objective: To compare the safety/efficacy of the robotic-assisted lobectomy/segmentectomy (RAL/S) with the video-assisted lobectomy/segmentectomy (VAL/S) for radical lung cancer resection. BACKGROUND: It remains uncertain whether the newly developed RAL/S is comparable with the VAL/S. METHODS: A comprehensive search of online databases was performed. Perioperative outcomes were synthesized. Cumulative meta-analysis was performed to evaluate the temporal trend of pooled outcomes...

OBJECTIVE: Increasing surgeon volume may improve outcomes for index operations. We hypothesized that there may be surrogate operative experiences that yield similar outcomes for surgeons with a low-volume experience with a specific index operation, such as esophagectomy. BACKGROUND: The relationship between surgeon volume and outcomes has potential implications for credentialing of surgeons. Restrictions of privileges based on surgeon volume are only reasonable if there is no substitute for direct experience with the index operation...
