Effects of Laparoscopic Sleeve Gastrectomy on Quality of Life Related to Gastroesophageal Reflux Disease.

Effects of laparoscopic sleeve gastrectomy (LSG) on gastroesophageal reflux disease (GERD) symptoms are controversial. Our aim is to evaluate the effects of LSG on GERD symptoms in obese patients using a validated quality-of-life questionnaire. Records of 100 patients (median body mass index [BMI] 44.4 kg/m, range 35-63.6) without hiatal hernia or severe GERD were analyzed. GERD symptoms were evaluated by GERD Health-Related Quality-of-Life (HRQL) questionnaire before and after surgery. Weight loss and comorbidity resolution were recorded. Median GERD-HRQL scores decreased from 7 (range 0-44) to 3 (0-34) ( = .025) (median follow-up 56 months [range 7-136]). GERD-HRQL scores improved in 55 patients and worsened in 21; GERD was observed in 10; no change occurred in 14 patients (differences being statistically significant:  = <.0001). On multilinear regression analysis, total preoperative GERD-HRQL score and postoperative BMI were independent variables for overall postoperative GERD-HRQL score: higher total preoperative GERD-HRQL score was associated with improved postoperative GERD-HRQL scores, whereas higher postoperative BMI was associated with worse total postoperative GERD-HRQL score. Resolution of diabetes, hypertension, and sleep apnea syndrome occurred in 84.4%, 68%, and 89.7% of patients, respectively. In obese patients, although LSG was associated with statistically significantly improved postoperative GERD-HRQL scores at mid-term follow-up in 55% of patients, only preoperative GERD-HRQL score and postoperative BMI were independent predictors of GERD after LSG. Higher overall preoperative GERD-HRQL score was associated with improved postoperative GERD-HRQL score. However, further research is needed to assess how to predict GERD outcome.
