Evaluation of nutritional deficiencies and health-related quality of life during the first year after laparoscopic sleeve gastrectomy and laparoscopic mini-gastric bypass

Abstract

Background Nutritional deficiencies and health-related quality of life represent a major concern after bariatric procedures and can cause serious complications. Bariatric procedures have different effects on the domains of quality of life. Objective To prospectively compare between the effects of laparoscopic sleeve gastrectomy (LSG) and laparoscopic mini-gastric bypass (LMGB) on nutritional deficiencies and quality of life during the first postoperative year. Patients and methods We included 40 patients. In the first group, 20 patients underwent LSG, whereas 20 patients in the second group underwent LMGB. Postoperative assessment of nutritional parameters and quality of life was performed every 3 months. Quality of life was assessed using bariatric analysis and reporting outcome system (BAROS) and short form-12 questionnaires. Results All nutritional parameters showed significant decrease with more significant deficiencies after LMGB. Quality of life improved significantly after both procedures. Using BAROS questionnaire, LMGB was associated with significant better results. Conclusion LSG and LMGB are associated with significant decrease of nutritional parameters and significant improvement of quality of life. However, LMGB is associated with significantly more nutritional deficiencies and better improvement of quality of life than LSG.
