Transit Bipartition After Sleeve Gastrectomy

Clinical, Metabolic, and Physiological Evaluation of Conversion From Sleeve Gastrectomy to Intestinal Transit Bipartition

Source: ClinicalTrials.gov · Last updated 3 Aug 2026

Brief summary (registry, in English)

This prospective, single-center study will evaluate adults undergoing revisional conversion from sleeve gastrectomy to intestinal transit bipartition. Forty participants will complete clinical, endoscopic, physiological, metabolic, hormonal, imaging, and stool assessments before surgery and during follow-up. The primary outcome is the within-participant change in solid-meal gastric emptying half-time (T½), measured by standardized scintigraphy from baseline to 6 months. Secondary and exploratory outcomes include reflux symptoms, DeMeester score and acid exposure, route-specific gastric transit, GLP-1 and ghrelin responses, glucose metabolism, fecal elastase, gut microbiota, body-weight trajectory, comorbidities, gastroileal anastomotic caliber, and safety.
