Brief summary (registry, in English)
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).
