Core Tip
Core Tip: This study leverages three-dimensional computed tomography reconstruction to analyze the early dilation of the residual stomach post-laparoscopic sleeve gastrectomy. It identifies significant factors influencing gastric dilation, including preoperative type 2 diabetes, initial postoperative residual gastric volume, and Gastroesophageal Reflux Disease Ques
