The Quality of life of patients with morbid obesity before and after gastric banding and gastric bypass

Abstract

In order to estimate the quality of life in bariatric surgery patients usually two scales are used: GIQLI (gastrointestinal Quality of life index) and BAROS (Bariatric analysis and reporting outcome system). In our work we used the original estimation of the quality of life, based on the questionnaire GIQLI. This questionnaire consists of two parts: universal and specific. For the estimation of the level of morbid obesity two main scores are utilized: overweight and the Body Mass Index (BMI). We estimated the quality of life of patients with morbid obesity before the operation (25 patients), after gastric banding (25 patients) and gastric bypass (25 patients). For the control group we show the answers for the same questionnaire of 26 volunteers without any chronic diseases, including morbid obesity. Gastric bypass was performed in patients with BMI more than 40 kg/m2, gastric banding was performed in patients with BMI less than 40 kg/m2. The median periods of supervising the patients after gastric bypass and gastric banding were 3±1,9 years and 4,3±1,7 years for each. After the surgery the percentage of reduction of the overweight was significantly higher in the patients after the gastric bypass. It means that the weight loss is more effective after gastric bypass than gastric banding. The index of the quality of life of the patients with the morbid obesity was much lower than in the control group (р<0,05). After the surgical treatment all the scores increased in the group of the patients being operated on, than in the group of the patients with obesity before the operations (р<0,05). While comparatively estimating the two operations we got practically the same results after gastric bypass and gastric banding. For gastric banding a very important index of the improvement of the quality of life is the level of the weight loss, but after the gastric bypass there were no such outcome.
