Abstract The aim of this study is to compare the short-term outcome of morbidly obese patients treated with one anastomosis gastric bypass with whom treated with SASI operation. Background: OAGB and SASI are two new operations of mini gastric bypass which have been common used in treatment of obesity recently Methods: This prospective controlled study had been conducted at General Surgery Department, Menoufia University, and it included 40 patients divided randomly into two groups, group A, included 20 morbidly obese patient whom treated with one anastomosis gastric bypass and group B included morbidly obese 20 patients treated with SASI. Results: A total of 40 patients were included in our study (20 in OAGB and 20 in SASI). OAGB conferred significantly higher %EWL at 12 months than SASI (88% vs 60% with p- value <0.001). Improvement in diabetes mellitus and hypertension after OAGB was better than SASI (100% vs 42%), (85vs 60%) respectively. OABG required longer operation time than SASI (164vs 156 minutes). SASI caused more nutritional deficiencies than OAGB. |
