Comparing the quality of life after laparoscopic roux-en-y gastric bypass and mini gastric bypass

Abstract

Objectives: The aim was to compare the quality of life after laparoscopic Roux-en-Y gastric bypass (LRYGB) and mini-gastric bypass (LMGB) in morbidly obese patients. Materials and Methods: From January 2012 to March 2014, we enrolled 40 patients who underwent LRYGB and LMGB. The mean age and body mass index (BMI) was 39 ± 4.8 years and 43.5 ± 6.5 (kg/m 2 ), respectively. Quality of life was measured by the gastrointestinal quality of life index (GIQLI), a 36 item questionnaire before and at 1-year after LRYGB and LMGB and was compared. Results: All procedures were performed laparoscopically with no conversions. The two groups were comparable in age, gender, and BMI. One year after bariatric surgery, the mean general score of GIQLI improved significantly ( P = 0.001). All patients had improvement in the four domains of the questionnaire (social function, physical status, and emotional status Despite a significant difference between two groups in postoperative physical and emotional domains of GIQLI scores ( P ≤ 0.05), the postoperative gastrointestinal quality of life was comparable in both the groups. Conclusion: Both LRYGB and LMGB are effective treatments for morbid obesity. Both procedures can significantly resolve obesity-related comorbidities and increase quality of life for morbidly obese patients. LMGB was shown to be a simpler and safer procedure than LRYGB with similar efficacy at the 1-year follow-up. LMGB is thus an acceptable alternative treatment to standard LRYGB for morbidly obese patients.
