Obesity has become the epidemic of this century, and is one of the biggest public health multifactorial problems. Currently, bariatric surgery is the only efficient treatment option leading to sustainable weight loss and reduction in comorbidities in morbidly obese patients.

The aim of this study was to assess the outcomes of LMGB in comparison to LRYGB as regard EWL%, resolution of co-morbidities and effects on patients’ QoL at one year follow-up.

This study was carried out on 80 morbidly super obese patients who were randomly assigned and distributed into 2 equal groups: Group (I): was submitted to LRYGB and Group (II): was submitted to LMGB.

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.

This study confirms the safety of LMGB as a bariatric procedure. Moreover, LMGB achieved a higher 1-year EWL% and better remission of obesity associated comorbidities. Thus, LMGB can be considered an acceptable alternative to LRYGB in management of morbidly obese patients.
