Abstract
Background: Gastric pouch volumetry after sleeve gastrectomy reflects successful surgery. We aimed to assess the impact of gastric pouch volume after sleeve gastrectomy on weight loss.
Method: The study was performed for 30 patients (22 females and 8 males) who underwent sleeve gastrectomy. Their ages ranged from 18 to 47 years. All patients underwent (multi‑slice CT) MSCT examination at 12 months after surgery with oral administration of effervescent emulsion. Post‑processing in multi‑planar reconstruction and 3D reconstruction was performed to all cases. Gastric pouch volume was measured and correlated with body weight, body mass index (BMI), % reduction in excess body weight and ∆weight at 1 year.
Results: A significant positive association was found among gastric volume pouch and weight loss (P = 0.04), BMI reduction (P value < 0.0001) and ∆weight (P value = 0.013). A significant inverse association was found among gastric pouch volume and % reduction in excess body weight (P value = 0.013).
Conclusion: MSCT gastric volumetry is the gold standard imaging method for assessment of the gastric pouch volume after sleeve gastrectomy. Significant positive association was found among gastric volume pouch and weight loss, BMI reduction and ∆weight at 1 year, i.e., in spite of large gastric pouch volume at 1 year, there is adequate weight loss, BMI reduction and ∆weight. Yet, significant inverse association was found among gastric pouch volume and % reduction in excess body weight.
