Antral Resection versus Antral Preservation during Laparoscopic Sleeve Gastrectomy: Does Outcome Differ?

Abstract

Background: The surgical technique of sleeve gastrectomy has not been fully standardized and, therefore, there are issues to be solved. Resection of the antrum is one of these debatable issues. Aim:The study aims at assessing the difference in long and short term weight loss between both antral resection laparoscopic sleeve gastrectomy & antral preservation laparoscopic sleeve gastrectomy.Patients and methods: Is a prospective randomized control study including 100 patients with BMI exceeding 35, fifty of them will undergo antral preservation in laparoscopic sleeve gastrectomy (group A), and the other fifty patients will undergo antral resection in laparoscopic sleeve gastrectomy (group B).Results: Weight loss and BMI reduction after 6 months in the antral resection group were more than the antral preservation group with mean weight 92.25 kg in antral resection group compared to 99.46 kg in antral preservation group and mean BMI 34.48 in antral resection group compared to 39.29 in antral preservation group. Also weight loss and BMI reduction after 12 months in the antral resection group were more than the antral preservation group with mean weight 71.60 kg in antral resection group compared to 77.20 kg in antral preservation group and mean BMI 26.41 in antral resection group compared to 30.71 in antral preservation group. Conclusion:Antral resection in LSG safely potentiates the restrictive effect achieved and may result in greater and better maintained weight loss.
