Antral Resection versus Antral Preservation during Laparoscopic Sleeve Gastrectomy for Morbid Obese Patients and its Influence on Weight Loss: A Prospective Randomized Study

Abstract

besity is a pandemic health problem in both developed and developing countries and the costs of care continue to grow in parallel with the prevalence of the disease. This morbid condition leads to a high incidence of complications and a decrease in life expectancy, especially among younger adults. Surgical treatment of morbid obesity results in significant sustained weight loss, which reduces obesity-related morbidity and increases survival compared with patients receiving optimal medical therapy. The aim of this study is to compare between antral resection (gastrectomy 2 cm from pylorus) and antral preservation (gastrectomy 6 cm from pylorus) during laparoscopic gastric sleeve and its influence on the percentage of weight loss, postoperative complications and nutritional and elemental deficiencies. This is a prospective randomized study that will be conducted in Ain-Shams University Hospitals bariatric surgery unit over 40 morbid obese patients with minimal follow-up of 12 months starting from September 2018 to September 2019. Patients were divided into 2 groups: Group A: composed of 20 patients assigned to antral resection sleeve gastrectomy (gastrectomy 2 cm from pylorus). Group B: composed of 20 patients assigned to antral preservation sleeve gastrectomy (gastrectomy 6 cm from pylorus).
