Evaluation of Quality of Life, Clinical Parameters, and Psychological Distress after Bariatric Surgery: Comparison of the Laparoscopic Sleeve Gastrectomy and Laparoscopic Greater Curvature Plication

摘要

Objectives: The aim of this prospective study was to compare the effect of two surgical methods, Laparoscopic Sleeve Gastrectomy (LSG) and Laparoscopic Greater Curvature Plication (LGCP), weight loss, and clinical parameters (fat, lean body mass [LBM], glycemia) on subjective perception of quality of life (QoL) regarding health and on anxiety and depression in obese patients during 12 months after the procedure. Further aim was to ascertain which clinical parameters contribute to a positive QoL after bariatric surgery. Methods: The research set consisted of 68 patients undergoing bariatric treatment (LSG and LGCP). QoL data were collected by means of the WHOQOL-BREF questionnaire, and the Hospital Anxiety and Depression Scale (HADS) was used to evaluate anxiety and depression. Patients filled the questionnaire before the planned surgery and later 3, 6, and 12 months after the planned surgery. Results: Body mass index (BMI) and body weight decreased, all monitored clinical parameters improved, and QoL, namely physical and psychological health, improved as early as 3 months after bariatric surgery (p<0.01). No statistically significant differences in monitored parameters were found between the surgery types. Regarding physical and psychological health, an association was determined between changes in QoL and changes in BMI and circumference of the hips. Conclusion: QoL improvement experienced after bariatric surgery is associated particularly with weight reduction and lower levels of anxiety and depression, but not with other clinical parameters.
