Assessment of the Correlation Between Preoperative and Immediate Postoperative Gastric Volume and Weight Loss After Sleeve Gastrectomy Using Computed Tomography Volumetry

Background Laparoscopic sleeve gastrectomy (LSG) has achieved excellent results in treatment of morbid obesity. The present study aimed to evaluate the impact of the preoperative gastric volume, volume of the remaining gastric pouch, and volume of the resected stomach on weight loss after LSG. Metho...

Description
Summary:Background Laparoscopic sleeve gastrectomy (LSG) has achieved excellent results in treatment of morbid obesity. The present study aimed to evaluate the impact of the preoperative gastric volume, volume of the remaining gastric pouch, and volume of the resected stomach on weight loss after LSG. Methods Patients with morbid obesity who underwent LSG were investigated by CT volumetry before and 1 week after LSG to measure the volume of the stomach before and after the procedure, and the volume of the resected stomach was also calculated. The percentage of excess weight loss (EWL) and decrease in body mass index (BMI) at 6 months postoperatively were measured and correlated with preoperative and postoperative gastric volumes. Results Forty-seven patients (44 females) were included to the study. A significant decrease in the gastric volume and BMI after LSG was noted. Preoperative gastric volume was positively correlated with preoperative BMI ( r  = 0.723, p
