Gastroesophageal reflux disease and morbid obesity: To sleeve or not to sleeve?

ABSTRACT: Laparoscopic sleeve gastrectomy (LSG) has reached wide popularity during the last 15 years, due to the limited morbidity and mortality rates, and the very good weight loss results and effects on comorbid conditions. However, there are concerns regarding the effects of LSG on gastroesophageal reflux disease (GERD). The interpretation of the current evidence is challenged by the fact that the LSG technique is not standardized, and most studies investigate the presence of GERD by assessing symptoms and the use of acid reducing medications only. A few studies objectively investigated gastroesophageal function and the reflux profile by esophageal manometry and 24-h pH monitoring, reporting postoperative normalization of esophageal acid exposure in up to 85% of patients with preoperative GERD, and occurrence of de novo GERD in about 5% of cases. There is increasing evidence showing the key role of the surgical technique on the incidence of postoperative GERD. Main technical issues are a relative narrowing of the mid portion of the gastric sleeve, a redundant upper part of the sleeve (both depending on the angle under which the sleeve is stapled), and the presence of a hiatal hernia. Concomitant hiatal hernia repair is recommended. To date, either medical therapy with proton pump inhibitors or conversion of LSG to laparoscopic Roux-en-Y gastric bypass are the available options for the management of GERD after LSG. Recently, new minimally invasive approaches have been proposed in patients with GERD and hypotensive LES: the LINX® Reflux Management System procedure and the Stretta® procedure. Large studies are needed to assess the safety and long-term efficacy of these new approaches. In conclusion, the recent publication of pH monitoring data and the new insights in the association between sleeve morphology and GERD control have led to a wider acceptance of LSG as bariatric procedure also in obese patients with GERD, as recently stated in the 5th International Consensus Conference on sleeve gastrectomy.

Project description:IntroductionLaparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB) are the most frequently performed procedures in bariatric surgery. In patients with morbid obesity and gastro-oesophageal reflux disease (GORD), LRYGB is the most accepted procedure. For patients with a contraindication for LRYGB or a strong preference for LSG, the Nissen-Sleeve procedure may be a viable new option. The aim of this study is to compare effectiveness of Nissen-Sleeve with LRYGB.Method and analysisThis is a single-centre, phase III, parallel-group randomised controlled trial in a high-volume bariatric centre in the Netherlands. A total of 88 patients with morbid obesity and GORD will be randomised to evaluate non-inferiority of Nissen-Sleeve versus LRYGB (non-inferiority margin 15%, power 80%, one-sided α 0.025, 9% drop out). Patients with morbid obesity aged 18 years and older with GORD according to the Montreal definition will be included after obtaining informed consent. Exclusion criteria are achalasia, neoplastic abnormalities diagnosed during endoscopy, super obesity (body mass index ≥50 kg/m2), Crohn's disease and medical history of major abdominal surgery. After randomisation, all patients will undergo an upper gastrointestinal endoscopy. Patients in the Nissen-Sleeve arm will undergo a timed barium oesophagram to exclude oesophageal motility disorders. Patients will complete six questionnaires at baseline and every year until 5 years of follow-up. At day 1 postoperative, patients in the Nissen-Sleeve arm will undergo a swallow X-ray to confirm passage. At 1 year, all patients will undergo another endoscopy. The primary outcome is GORD status. Absence of GORD is defined as <8 points on the GORD questionnaire. Secondary outcome measures are long-term GORD improvement; failure rate of procedure; health-related quality of live; weight loss; proton pump inhibitor use; postoperative complications <30 days and >30 days; length of hospital stay; duration of primary surgery; effect on comorbidities; presence and grade of oesophagitis (grade A-D) and/or presence of Barrett's oesophagus and cost-effectiveness.Ethics and disseminationThe protocol was approved by the Medical Research Ethics Committees United (MEC-U), Nieuwegein, on 15 September 2021. Written informed consent will be obtained for all participants in the study. The study results will be disseminated through peer-reviewed publications and conference presentations.Trial registration numberNL9789; The Netherlands Trial Registry.
