Abstract
Purpose:
The study aims to evaluate the potential benefit of omental reattachment in laparoscopic sleeve gastrectomy (LSG) and its effect on food tolerance and gastric emptying (GE).
Patients and Methods:
This prospective study included 40 morbidly obese adults scheduled for LSG from January 2017 to January 2018. They were randomly assigned into one of two groups: reattachment group (n = 20) had omental reattachment at the end of LSG and non-reattachment group (n = 20) had LSG without omental reattachment. Food tolerance was assessed using the Suter's questionnaire, and GE was studied radiologically 2–3 months after the operation.
Results:
GE of liquids and solids was significantly faster in the non-reattachment group. Liquid emptying T½ in the reattachment group was 25.0 ± 6.2 min compared to 11.8 ± 3.0 min in the non-reattachment group (p < 0.001). Solid emptying T½ in the reattachment group was 49.0 ± 13.8 min compared to 28.4 ± 8.3 min in the non-reattachment group (p < 0.001). There was no significant difference between the two groups in percentage of excess weight loss (p = 0.581) and the total score of food tolerance (p = 0.529).
Conclusion:
Reattaching the greater omentum to the new greater curvature of the gastric sleeve during LSG delays GE of liquids and solids as evidenced by gastric scintigraphy. This delay was not associated with food intolerance.
