Abstract

Background: The most effective therapy for obesity is bariatric surgery. In addition to weight loss, it also significantly
reduces mortality and improves comorbidities associated with obesity within a significant proportion of patients.
Laparoscopic sleeve gastrectomy (LSG) and laparoscopic greater curvature gastric plication (LGCP) are both restrictive
bariatric surgeries. LSG is considered the most performed worldwide. We aimed to compare the residual gastric volume
(RGV) after LSG and LGCP and correlate this volume with weight loss.
Patients and Methods: This was a comparative cohort study performed on 40 obese cases assigned into two groups. Group
A underwent LGCP and group B underwent LSG. All cases in both groups underwent multislice computed tomography
gastric volumetry after 3 months to assess RGV. The excess weight loss percentage (EWL%) was subsequently correlated
with the RGV 6 months’ postsurgery.
Results: In this study, group A had a significantly higher average of RGV in comparison to group B (357.9±79.9 vs.
132.4±44.4, P<0.001). Group A had higher EWL% in comparison to group B (59.1±17.7 vs. 52.5±9.1, P=0.076).
Conclusion: RGV might be able to predict the EWL% following LGCP and LSG. The less the RGV, the greater the
EWL%. LGCP is an effective operation for weight loss despite relatively high RGV.
