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.
