Impact of mini-gastric bypass surgery on the quality of life of patients with morbid obesity

Objective. The aim of the study is to examine the relationship between biliopancreatic limb length and quality of life in obese patients after mini-gastric bypass surgery (GIQLI questionnaire). Materials and Methods. The study included 282 patients who had undergone surgery. The patients were divided into two groups based on the biliopancreatic limb length. The first (main) group comprised 160 morbidly obese patients with a limb length of 150 cm, and the second (comparison) group included 122 patients with a limb length of 180 cm. The groups were comparable in terms of sex, age, BMI, and comorbidities. The Gastrointestinal Quality of Life Index (GIQLI) questionnaire was distributed via Google Forms 24 months postoperatively. Statistical analysis was carried out using the software packages Statistica 12.2 StatSoft (StatSoft, Inc. Tulsa, USA) and SPSS version 21 (SPSS, Chicago, IL, USA). Results. The obtained data demonstrate the dependence of the postoperative patient-reported quality of life assessment on the biliopancreatic limb length. Specifically, the total score on the GIQLI questionnaire was higher in the first group than in the second one. A comparative analysis of the groups by individual components revealed that the scores for psycho-emotional status and social adaptation were comparable (p=0.64 and p=0.8, respectively). However, the differences in physical status were significant: the score for this component in the main group was 57.47±5.35, while in the comparison group it was 46.33±11.41 (p=0.01). Thus, the biliopancreatic limb length significantly influenced the physical condition of the patients, reflecting the problems with the gastrointestinal tract.
