Study Description

Brief Summary: LSG is thought to be the best choice for obese patients with conincidental GISTs, as a tumour can be resected along with resecting the stomach within the same procedure. The primary endpoint is that, how much does GIST suppose to be far from a staple line to do safe laparoscopic sleeve gastrectomy

Detailed Description: The incidence of unsuspected GIST in LSG specimens in our series was high in comparison to cases reported in the literature. GISTs could be safely removed laparoscopically during LSG surgery with negative microscopic resection margins, with 1-2cm safety margin. Margins less than 1cm, high mitotic rate are adverse prognostic factors. Examining the whole stomach before resection is mandatory and can easily be done during LSG, GIST can be removed safely with LSG
