Gastrointestinal quality of life after laparoscopic Roux-en-Y gastric bypass

Background: Laparoscopic Roux-en-Y gastric bypass (LRYGBP) is a commonly performed bariatric surgical procedure for the treatment of morbid obesity (MO). Obesity-related co-morbiditles reduce the quality and expectancy of life. We assessed gastrointestinal quality of life in patients following LRYGBP. Methods: The Gastrointestinal Quality of Life Index (GIQLI test) was used in this study. A higher score correlates with better quality of life. The GIQLI test was administered to 3 non-selected groups: 100 morbidly obese patients (MO group), 100 patients who had undergone LRYGBP (LRYGBP group); and a control group of 100 individuals (CO group). The CO group was composed of healthy individuals with a BMI < 30 kg/m(2), consecutively recruited among the companions of patients who came for a surgery consultation for obesity or other pathologies. Overall test and specific dimensions scores were evaluated for each group. Results: Overall test and specific dimensions scores were significantly lower in patients with MO when compared to the CO and LRYGBP groups. There were no differences between the CO and LRYGBP groups in the overall score with regard to disease-specific digestive symptoms and the psychological and social dimensions. Conclusions: The quality of life of morbidly obese patients is worsened not only because of the presence of digestive symptoms but also because of their emotional, physical and social impact. Patients operated on by LRYGBP experience an improvement in their quality of life, with good tolerance of the anatomical changes.
