Implementing novel modalities into an institutional enhanced recovery after bariatric surgery (ERABS) protocol.

INTRODUCTION: Enhanced recovery after bariatric surgery pathways are associated with improved postoperative outcomes. This study aims to assess efficacy and safety of three novel protocol contributions (transversus abdominis plane blocks, ketamine and fosaprepitant), as well as their impact on length of stay (LOS) and on postoperative complications. METHODS: Effectiveness and safety were retrospectively investigated in patients who underwent Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG) over a 6-year period in a single institution. Group 1 patients were not exposed to any of our suggested interventions, whereas Group 2 were exposed to all of three. RESULTS: Between January 2015 and August 2021, 1480 patients underwent primary SG (77.6%) or RYGB (22.4%); of those, 1132 (76.5%) and 348 (23.5%) were in Groups 1 and 2, respectively. Mean BMI and age were 45.87 versus 43.65 kg/m2 and 45.53 versus 44.99 years in groups 1 and 2, respectively. Suggested interventions were associated with lower operative times (84.79 ± 24.21 vs. 80.78 ± 32.8 min, p = 0.025). In Group 2, the mean LOS decreased in 0.18 day (1.79 ± 1.04 vs. 1.60 ± 0.90; p = 0.004). Overall complication rates were 8% and 8.6% for groups 1 and 2, respectively; readmission rates were 5.7% (64 pts) vs. 7.2% (25 pts), p > 0.05. Reoperations were less prevalent in Group 2 (1.5% vs. 1.1%; p = 0.79). CONCLUSION: Focus on optimized pain management, allied to a superior PONV control, may be relevant contributors for a lower LOS without negative impacts in complications rates.

Race-Related Differences in the Clinical Presentation and Histopathologic Features of Phyllodes Tumor.

BACKGROUND: Phyllodes tumor (PT) is a rare fibroepithelial lesion of the breast with variable malignant potential. Black women have a higher incidence of a related benign tumor, fibroadenoma, but there are limited epidemiological data on PT. The aim of our study was to evaluate race-related differences in the clinicopathologic features and outcomes of PT. METHODS: Our institutional pathology database was queried for breast specimen reports from 01/2009 to 10/2019 to identify patients with a pathologic diagnosis of PT. Chart review and detailed slide review were performed to obtain clinical and histopathologic variables, respectively. RESULTS: Among twelve patients, two had malignant PT, three had borderline PT, and seven had benign PT. All patients with malignant and borderline PT were black, compared with 29% of those with benign PT. There were no apparent race-related differences in specific histopathologic features among black vs. non-black women with benign PT. Malignant and borderline PT were relatively larger than benign PT, with mean tumor sizes of 9.0 cm (standard deviation [SD] 4.7 cm), 12.2 cm (SD 9.4 cm), and 5.4 cm (SD 5.8 cm), respectively. Two women had a local recurrence, both of whom were black. DISCUSSION: In this single-institution retrospective study, we observed disproportionate rates of aggressive histopathologic features and disparate outcomes among black women with PT. A multi-institutional PT registry would facilitate improved knowledge about race-related differences in the presentation and outcomes of this rare tumor.
