Comparison of Weight Loss and Nutritional Deficiency After One Anastomosis Gastric Bypass at 150, 170, and 200 cm From the Duodenojejunal Junction

Brief summary (registry, in English)

This study is a randomized clinical trial comparing the effects of One Anastomosis Gastric Bypass performed at three different distances from the duodenojejunal junction-150 centimeters, 170 centimeters, and 200 centimeters-on weight loss outcomes and nutritional status in patients with obesity. One Anastomosis Gastric Bypass is a type of bariatric surgery that combines aspects of a gastric sleeve and a traditional gastric bypass, aiming to achieve effective weight loss and improvement in health conditions associated with obesity. The study will include 60 adult patients between 18 and 60 years old with a Body Mass Index of 35 kilograms per square meter or greater, or a Body Mass Index of 30 kilograms per square meter or greater with obesity-related health conditions, who have not achieved adequate results through diet, exercise, or medication. Participants will be randomly assigned to one of three groups, each undergoing One Anastomosis Gastric Bypass with a different limb length from the duodenojejunal junction: 150 centimeters, 170 centimeters, or 200 centimeters. The primary outcomes measured will include the percentage of total weight loss, the percentage of excess weight loss, and postoperative nutritional status, particularly in terms of levels of albumin, calcium, iron, and ferritin. Secondary outcomes will assess the remission of health conditions related to obesity, including high blood pressure and type 2 diabetes mellitus, as well as patient quality of life following surgery. By examining the impact of One Anastomosis Gastric Bypass at varying limb lengths on weight loss and nutritional deficiencies, this study aims to identify an optimal surgical approach that balances effective weight management and minimizes the risk of postoperative malnutrition. The findings will inform surgical decision-making and postoperative management strategies for individuals undergoing One Anastomosis Gastric Bypass.
