Abstract

Background: There has been a rapid increase in prevalence of obesity, and bariatric surgery is the most effective treatment to reduce all-cause mortality. Gastrointestinal stromal tumors (GISTs) comprise approximately 1% of GI tumors and are the most commonly encountered incidental tumor at the time of bariatric surgery. They have a reported prevalence of approximately 0.5%; however, there are no established guidelines for incidental GISTs.

Methods: This study performed a systematic literature search using PubMed to identify 100 articles from 2005 to 2023 on incidental GIST tumors found during bariatric operations.

Results: Total prevalence of GISTs was 0.54% with an average size of 7.04 mm. Management of these lesions should prioritize negative margins with the least invasive resection. Tumors able to be resected without alteration to bariatric surgery should be managed with a complete wedge resection prioritizing negative margins. In tumors where resection requires alteration to bariatric surgical plan, the decision to proceed with resection and alteration of bariatric surgical plan should be made only if previous discussions have been made with patient. Lastly, if resection of the GIST precludes the ability to perform the bariatric procedure, consideration to resect the GIST with the goal of negative margins should be prioritized with a plan to discuss future bariatric procedures after.

Conclusion: The goal of this paper is to remind bariatric surgeons to be aware of GISTs and provide the possible approaches to management.

期刊介绍： Obesity Surgery is the official journal of the International Federation for the Surgery of Obesity and metabolic disorders (IFSO). A journal for bariatric/metabolic surgeons, Obesity Surgery provides an international, interdisciplinary forum for communicating the latest research, surgical and laparoscopic techniques, for treatment of massive obesity and metabolic disorders. Topics covered include original research, clinical reports, current status, guidelines, historical notes, invited commentaries, letters to the editor, medicolegal issues, meeting abstracts, modern surgery/technical innovations, new concepts, reviews, scholarly presentations and opinions. Obesity Surgery benefits surgeons performing obesity/metabolic surgery, general surgeons and surgical residents, endoscopists, anesthetists, support staff, nurses, dietitians, psychiatrists, psychologists, plastic surgeons, internists including endocrinologists and diabetologists, nutritional scientists, and those dealing with eating disorders.
