Summary

The global obesity epidemic has led to increasing popularity of bariatric surgeries and a parallel rise in the prevalence of related complications. Gastric sleeve stenosis (GSS) complicates 0.1-3.9% of cases after Sleeve Gastrectomy (SG) and can result in significant symptoms including nausea, vomiting, epigastric pain, dysphagia, reflux and regurgitation. There is no validated algorithm for the management of GSS, and available literature is retrospective.

The investigators hypothesize that the implementation of a predefined treatment algorithm for management of GSS post SG will effectively and safely manage patients with this condition. This single center, prospective, non-randomized pilot clinical trial to be performed at Johns Hopkins Medical Institutes will describe the efficacy and safety of endoscopic pneumatic balloon dilation (PBD), gastric peroral endoscopic myotomy (G-POEM) and Roux-en-Y gastric bypass (RYGB) for the management of post-LSG GSS using a predefined treatment algorithm. Patients with symptomatic, endoscopically or radiologically confirmed GSS greater than four weeks from laparoscopic sleeve gastrectomy (LSG) who are treatment nave will be included.

The primary outcome is the rate of clinical success, defined an improvement in symptoms that allowed the patient to avoid further intervention (outside of the predefined treatment algorithm) with a resumption of adequate oral intake and at least 1-point reduction in the Patient Assessment of upper Gastrointestinal Symptoms (PAGI-SYM) questionnaire, at 6 months following last intervention. Secondary outcomes include rates of technical success (completion of planned procedure), procedural success (defined as a 1-point reduction in PAGI-SYM score at 8 weeks following procedure), endoscopic and radiologic resolution of GSS-related findings, percentage of patients maintained off proton pump inhibitor (PPI) therapy, time to recurrence of symptoms post-treatment in patients with recurrence, and rate of adverse events. The expected study population is 30 participants with a study duration of 18 months. This study can potentially validate a treatment algorithm, thereby assisting clinicians to select the most appropriate intervention for the treatment of post-LSG GSS. Moreover, it may help improve outcomes and prevent unnecessary procedures in patients with GSS.
