This study represents a long-term observational follow-up of patients who had previously undergone bariatric surgery (laparoscopic sleeve gastrectomy or Roux-en-Y gastric bypass) in the context of an earlier interventional trial (NCT03692455). No new interventions are assigned in the follow-up phase. Participants are evaluated clinically and functionally at predefined intervals using standardized multimodal assessments (symptom questionnaires, endoscopy, manometry, radiology, and pH monitoring).Read full original descriptionShow less
Effect of Laparoscopic Sleeve Gastrectomy Versus Roux-en-Y Gastric Bypass on Gastroesophageal Reflux Disease: An 8-Year Prospective Cohort Study.
This study represents a long-term observational follow-up of patients who had previously undergone bariatric surgery (laparoscopic sleeve gastrectomy or Roux-en-Y gastric bypass) in the context of an earlier interventional trial (NCT03692455). No new interventions are assigned in the follow-up phase. Participants are evaluated clinically and functionally at predefined intervals using standardized multimodal assessments (symptom questionnaires, endoscopy, manometry, radiology, and pH monitoring).
Inclusion: Patients enrolled in a previous prospective dual-cohort extension with 75 patients of the original Trial; Original Inclusion Criteria: Inclusion criteria were age 18-70 years and body mass index (BMI) ≥40 kg/m², or ≥35 kg/m² with obesity-related comorbidities.
