Comparison between antral resection in laparoscopic sleeve gastrectomy and classical laparoscopic sleeve gastrectomy

Background: Laparoscopic sleeve gastrectomy (LSG) is essentially a restrictive bariatric operation. Weight loss is achieved by drastically reducing the gastric volume, which in turn leads to reduced food intake. In addition, a series of hormonal changes occurring postoperatively in bariatric patients, contribute to decreased appetite, reduced food intake and long-term weight loss. To date there is a lack of standardization regarding the surgical technique of LSG, which may affect the long-term outcome of the patients. Our study aimed to assess the difference in short and long- term weight loss and complications between antral resection in laparoscopic sleeve gastrectomy and classical laparoscopic sleeve gastrectomy with antral preservation. Patients and Methods:This is a controlled clinical trial held in Ain Shams University Hospital including 40 patients with BMI >30, of them 20 underwent antral resection in laparoscopic sleeve gastrectomy, and the other 20 patients underwent classical laparoscopic sleeve gastrectomy, with antral preservation. Results: Our study showed mild increase in weight loss and BMI reduction after 12 months in the antral resection group compared with the antral preservation group with mean weight loss 70.5kg in antral resection group versus 75.05kg in antral preservation group and mean BMI 27.7% in antral resection group versus 27.9% in antral preservation group, but did not reach statistical significant values. Conclusion: Our study showed that antral resection in laparoscopic sleeve gastrectomy resulted in non-significant better weight loss in the first postoperative year than classical laparoscopic sleeve gastrectomy.
