Abstract

Case series Patients: — Final Diagnosis: Obesity recidivism after sleeve gastrectomy Symptoms: Disphagia • heartburn • reflux • early satiety • nausea • regurgitation Clinical Procedure: — Specialty: Surgery Objective: Unusual clinical course Background Sleeve gastrectomy (SG) is widely used in obesity treatment, although it is associated with new onset of gastroesophageal reflux disease (de novo GERD) and weight regain. Roux-en-Y gastric bypass (RYGB) is the standard revisional procedure for GERD, though it offers limited additional weight loss. Ileal-based procedures have demonstrated superior outcomes regarding weight loss but have uncertain results in GERD. This study presents preliminary findings on gastric bipartition with functional duodenal exclusion (GBp-FDE) as a revisional approach following SG in this scenario. Case Reports A retrospective data analysis was conducted on 10 patients who underwent GBp-FDE due to de novo GERD and obesity recurrence after SG (mean BMI: 37.2±3.2 kg/m2). Nine patients presented with hiatal hernia and 8 with sleeve dilation. GERD was assessed pre- and postoperatively using a validated questionnaire, endoscopy, and contrast radiology. The surgical technique involved a pre-pyloric antroileostomy in Roux-en-Y configuration using a 40% proportion biliopancreatic limb. One-year postoperative findings included pyloric spasm (endoscopy), very preferential contrast flow to the ileum (radiology), and endoscopic access preservation to the…

How strong is the evidence?

Evidence Hub reads this as a case series, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health. Reported size: 10 participants or records.
