Abstract
BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) has gained popularity as a treatment of choice for morbid obesity and associated comorbidities. There has been a concern about new onset or worsening of gastroesophageal reflux (GERD) following LSG. OBJECTIVE: The objective of the study was to evaluate the effect of surgically treating hiatal weakness on GERD symptoms in patients undergoing LSG. SETTING: Single tertiary referral institution, Sydney, Australia. METHODS: A prospective observational cohort study was conducted with consecutive patients undergoing LSG. Hiatal findings, patient demographics, medications and reflux score were recorded prospectively. Patients were followed up post-operatively for a minimum of 12 months and assessed using GERD-HRQL score to quantify reflux symptoms. RESULTS: Data from 100 patients with a minimum of 1-year follow-up were analysed. Mean follow-up was 18.9 months. Overall, GERD-HRQL improved from mean 4.5 ± 5.8 pre-operatively to 0.76 ± 1.5 after 18.9 months (p = 0.0001). For those with pre-operative reflux, GERD-HRQL improved from mean (SD) 8.43 ± 6.26 pre-operatively to 0.94 ± 1.55 (p = 0.0001). All the nine patients with troublesome daily reflux significantly improved. For those without pre-operative reflux, GERD-HRQL improved from 0.88 ± 1.37 to 0.47 ± 1.25 (p-ns) post-operatively. On multivariate analysis, higher pre-operative reflux and dysphagia/bloat scores, younger age and lower percentage excess weight loss after 18.9 months were associated with GERD-HRQL improvement. CONCLUSION: In the medium term, GERD-HRQL improves following sleeve gastrectomy with meticulous hiatal assessment and repair of hiatal laxity and herniation.
