10-Year outcomes of marginal ulcer formation and impact of gastrojejunostomy technique in Roux-en-Y gastric bypass.

Background: Marginal ulcers (MUs) are potential complications following Roux-en-Y gastric bypass (RYGB) surgery. Our institution performs 3 different laparoscopic gastrojejunal anastomosis (GJA) techniques. The aim of this study was to analyze the incidence of MUs between 25-mm circular stapler (CS), linear stapler (LS), and hand-sewn (HS) GJA techniques using data collected over a 10-year period.

Comparative analysis of cold-stored apheresis platelet units in additive solution with or without pathogen reduction: Implications of cytochrome c supplementation.

Background: Platelets are limited in supply, and the preservation of platelet function during storage remains challenging. Novel storage approaches are being explored to improve platelet quality, extend shelf life, and reduce risk of infection. This study sought to elucidate platelet function in cold-stored apheresis units in additive solution (platelet additive solution [PAS]) and subjected to pathogen reduction (PR) as well as the impact of cytochrome c (cyt c) supplementation.

Toward Large Ablations With Single-Needle High-Frequency Irreversible Electroporation in Vivo.

Irreversible electroporation (IRE) is a minimally thermal tissue ablation modality used to treat solid tumors adjacent to critical structures. Widespread clinical adoption of IRE has been limited due to complicated anesthetic management requirements and technical demands associated with placing multiple needle electrodes in anatomically challenging environments. High-frequency irreversible electroporation (H-FIRE) delivered using a novel single-insertion bipolar probe system could potentially overcome these limitations, but ablation volumes have remained small using this approach.

Metabolic and Bariatric Surgery Outcomes in African American Patients: a Single Institution Experience.

Background: The incidence of obesity in African Americans (AAs) is higher than in non-AA in the USA. Previous studies using large national databases report that AA patients have worse outcomes than non-AA patients.

Objectives: To assess perioperative outcomes among AA patients after MBS at a center of excellence (COE) that serves a large, diverse patient population.

Analysis of technical failure after 1,613 surgical microwave ablations: A propensity score-matched analysis.

Background: Microwave ablation is becoming increasingly common for the treatment of liver tumors. Despite numerous studies aimed at identifying risk factors for local recurrence after microwave ablation, a consensus on modifiable risk factors for failure remains elusive, partly because of the limited statistical power of these studies. This study investigated the incidence of technical failure after microwave ablation, encompassing both incomplete ablation and local recurrence, and aimed to identify modifiable factors that reduce technical failure.
