Abstract
Obesity has become one of the fastest-growing and greatest health problems in both developed and developing countries. Morbid obesity (MO) leads to complications affecting nearly every organ system and a decrease in life expectancy as well. The World Health Organization defines overweight as a body mass index (BMI) of 25 Kg/m2 or more and obesity as a BMI of 30 Kg/m2 or more. Obese patients are further categorized into class I (BMI 30–34.9 Kg/m2), class II (BMI 35–39.9 Kg/m2) and class III (BMI 40 Kg/m2 or more). Patient with BMI >50 Kg/m2 considered to be superobese. The National Institutes of Health (NIH) established guidelines for surgical therapy for morbid obesity (BMI ≥ 40 or BMI ≥ 35 in the presence of substantial comorbidities), and since then the number of bariatric surgical procedures has dramatically increased Laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB) are currently the most commonly performed bariatric operations, but one anastomosis gastric bypass (OAGB) becomes increasingly performed to be the third commonly performed primary bariatric procedure after LSG and RYGB. The purpose of this study is to compare the 1-year follow up results of morbidly obese patients treated with one anastomosis gastric bypass (OAGB) with whom treated with sleeve gastrectomy (SG) in terms of excess weight loss (EWL), resolution of comorbidities, complications and nutritional deficiencies.
Based on our study, both OAGB & LSG are safe & effective in treatment of MO but OAGB had greater effect especially in morbidly obese patients with preoperative BMI ≥45Kg/m2 in terms of excess weight loss & improvement of comorbidities than LSG after one year without an increase in post-operative major complications. On the other hand, OAGB caused more nutritional deficiencies than LSG at one year follow-up, however, this was improved by using multivitamin supplementations.
