Introduction: Laparoscopic resection has been reported as reasonable for patients with gastrointestinal stromal tumors (GISTs). In this study, we report the feasibility of the laparoscopic approach for GIST of the stomach. We also discuss the laparoscopic approach for GIST larger than 5 cm, which is reported to be difficult to treat by laparoscopic surgery.
Materials And Methods: We retrospectively reviewed 22 patients with GIST of the stomach resected by laparoscopic or open procedures between January 2006 and February 2014.
Results: Laparoscopic resections were performed in 9 patients and open resections in 13 patients. Curative resections with negative resection margins were successfully completed for all patients. Although the size of the tumors was greater in open surgery cases than in laparoscopic patients (P = 0.03), the loss of blood was lower and the hospital stay was shorter in laparoscopic cases (P = 0.01 and 0.003, respectively). Laparoscopic resection was performed for 2 patients with GISTs larger than 5 cm. Both were located at greater curvature, and curatively resected without any complications or recurrence.
Discussion: Our experience suggests that laparoscopic surgery for GISTs of the stomach, including those larger than 5 cm, may be feasible after careful deliberation of its indications. Laparoscopic resection for GIST was associated with lower loss of blood and shorter hospital stay in comparison with open resection.

Early Reinitiation of Obesity Pharmacotherapy Post Laparoscopic Sleeve Gastrectomy in Youth: A Retrospective Cohort Study.
Obes Surg
January 2025
Division of Upper Gastrointestinal and General Surgery, Department of Surgery, Keck Medical Center of University of Southern California, Los Angeles, USA.
Background: Bariatric surgery is the most effective intervention for severe pediatric obesity, but a subset of youth experience suboptimal weight loss and/or recurrent weight gain. Early re-initiation of obesity pharmacotherapy postoperatively may improve outcomes, though this has not been evaluated in pediatric populations.
Methods: A retrospective cohort study at a tertiary care children's hospital evaluated the safety and efficacy of reintroducing obesity pharmacotherapy within six weeks after laparoscopic sleeve gastrectomy (LSG).
Background: To investigate the effectiveness of different bariatric metabolic surgeries in improving metabolic syndrome indicators in patients.
Methods: A retrospective analysis was conducted on obese patients who underwent laparoscopic sleeve gastrectomy (LSG), laparoscopic sleeve gastrectomy + jejunojejunal bypass (LSG + JJB), and laparoscopic Roux-en-Y gastric bypass (LRYGB). Patients were categorized into groups based on their surgical procedure: LSG (N = 199), LSG + JJB (N = 242), and LRYGB (N = 288).
Do transversus abdominis plane (TAP) blocks improve pain after laparoscopic bilateral inguinal hernia repairs beyond the recovery unit? A randomized control trial.
Hernia
January 2025
Department of Surgery, Icahn School of Medicine at Mount Sinai, One Gustave L. Levy Place, Box 1259, New York, NY, 10029, USA.
Purpose: While surgeons agree that perioperative field blocks should be performed for open inguinal hernia surgery, there lacks consensus in the minimally invasive context. Prior small-scale randomized trials study pain scores only up to 24 h postoperatively. Thus, we sought to investigate the analgesic benefits of a bupivacaine transversus abdominis plane (TAP) block in the first 4 postoperative days.

Introduction: The objective of this study is to compare the 5 year overall survival of patients with stage I-III colon cancer treated by laparoscopic colectomy versus open colectomy.
Methods: Using Mecklenburg-Western Pomerania Cancer Registry data from 2008 to 2018, we will emulate a phase III, multicenter, open-label, two-parallel-arm hypothetical target trial in adult patients with stage I-III colon cancer who received laparoscopic or open colectomy as an elective treatment. An inverse-probability weighted Royston‒Parmar parametric survival model (RPpsm) will be used to estimate the hazard ratio of laparoscopic versus open surgery after confounding factors are balanced between the two treatment arms.
Risk factors for anastomotic leakage in rectal cancer surgery reflecting current practices.
Surg Today

Department of Surgery, Yokohama City University Hospital, 3-9, Fukuura, Kanazawa-Ku, Yokohama, Kanagawa, 236-0004, Japan.
Purpose: In recent years, major advancements have been made in rectal cancer surgery with the introduction of new techniques such as robotic surgery and indocyanine green fluorescence imaging (ICG-FI). This study aimed to evaluate the comprehensive risk factors for anastomotic leakage (AL) following rectal cancer surgery, incorporating recently introduced techniques and other existing factors, to reflect current practices.
Methods: A retrospective analysis was conducted of 304 patients who underwent either robotic or laparoscopic anterior resection between January 2019 and December 2023.
