Outcomes of laparoscopic one-anastomosis gastric bypass in treatment of morbid obesity: a retrospective analysis

Abstract

Background Laparoscopic one-anastomosis gastric bypass (OAGB) is a promising bariatric procedure with multiple apparent benefits. However, concerns have been expressed about reported complication rates and the extent of follow-up, with recommendations to establish a registry of complications and revisional procedures. Aim of study To retrospectively analyze outcomes of OAGB performed for treatment of morbid obesity regarding weight loss, improvement in comorbid conditions, complications, and quality of life. Patients and methods OAGB was performed for the treatment of morbid obesity in 60 patients, and they completed at least 1 year of follow-up postoperatively at the Gastrointestinal Surgery Unit, General Surgery Department, Tanta University, Egypt. Results The study population included 60 patients, with a mean age of 33.52±8 years. The mean preoperative;Deg;BM;Deg;I was 53.29±6.91 kg/m2. Early complications were encountered in eight (13.3%) patients. Late complications occurred in 21 (35%) patients: nutritional sequelae developed in eight (13.4%) patients, four (6.7%) patients developed gall stones, gastritis owing to biliary reflux occurred in eight (13.4%) patients, and severe malnutrition developed in one (1.7%) patient. Preoperative obesity-related comorbidities were hypertension in 11 cases and diabetes mellitus in seven cases. The mean;Deg;BM;Deg;I 24 months after surgery was 34.14±4.17 kg/m2. Most of the comorbidities improved or resolved; 81.8% for hypertension and 85.6% for diabetes mellitus. Conclusion OAGB surgery is an easy, safe, and effective bariatric surgical technique for the treatment of morbidly obese patients producing significant weight loss, resolution or improvement of comorbidities, and improvement of patient quality of life. Strict postoperative follow-up with surveillance for vitamins, protein, and minerals deficiencies is essential, and endoscopic examination when indicated is recommended.
