The demographic data between both groups were comparable with mean
preoperative BMI of 56.73 kg/m2 and 59.70 kg/m2 in group I and II respectively. Our results showed that LMGB has a significantly shorter operative time than LRYGB (176.4 in group I vs 110.5 min in group II). The overall intraoperative complications occurred in 10 patients that were minor and managed laparoscopically without conversion to open surgery. The post-operative complications were anaemia (5% vs 12.5%) and hypocalcemia (5% vs 10%), GERD (2.5% vs 74.2%), and dumping (7.5% vs 2.5%). There were better results of LMGB than LRYGB as regard EWL%, remission rates of co-morbidities and improvement of QoL at one year follow-up but this difference did not achieve a statistically significant difference.
