Study Overview
Brief Summary
This prospective randomized study aimed to evaluate the effect of omentopexy performed during laparoscopic sleeve gastrectomy (LSG) on incisura angularis morphology, gastric emptying time, postoperative dyspeptic symptoms, and early weight loss outcomes. Patients undergoing primary LSG were randomized to either LSG with omentopexy or LSG without omentopexy. Gastric emptying was assessed using scintigraphic gastric emptying studies, and changes in incisura angularis angle were evaluated using intraoperative image analysis. Postoperative symptoms were assessed using the Short Form Leeds Dyspepsia Questionnaire.
Detailed Description
Laparoscopic sleeve gastrectomy (LSG) is one of the most commonly performed bariatric surgical procedures worldwide. However, postoperative gastrointestinal symptoms, gastric torsion, and functional stenosis remain important concerns after surgery. Omentopexy has been proposed as a technical modification to stabilize the gastric tube and preserve anatomical alignment, but its clinical and functional effects remain controversial.
This prospective randomized controlled study was conducted to evaluate the effect of omentopexy performed during LSG on incisura angularis morphology, gastric emptying time, postoperative dyspeptic symptoms, and early weight loss outcomes. Eligible patients undergoing primary LSG were randomized into two groups: LSG with omentopexy and LSG without omentopexy.
The incisura angularis angle was evaluated using intraoperative image analysis. Gastric emptying time was assessed preoperatively and at the postoperative third month using scintigraphic gastric emptying studies (T½). Postoperative dyspeptic symptoms were evaluated using the Short Form Leeds Dyspepsia Questionnaire. Demographic, clinical, laboratory, and postoperative outcome data were prospectively recorded and compared between groups.
