Robotic versus laparoscopic conversion to RYGB for revision bariatric surgery
Comparison of the Occurrence of Postoperative Complications Between Robotic and Laparoscopic Surgery in Revision Bariatric Surgery
We will see if robotic surgery or laparoscopy leads to fewer postoperative complications for people having revision bariatric surgery converted to RYGB.

What this trial studies
This is an observational comparison of patients undergoing revision bariatric procedures converted to Roux-en-Y gastric bypass who are managed with either robotic surgery or conventional laparoscopy according to the treating surgeon's protocol. The primary outcome is the rate of postoperative complications classified by the Clavien–Dindo system. Secondary outcomes include total operative time, emergency-room stay and hospitalization length, postoperative pain, adverse events, weight loss, and changes in comorbidities. The protocol does not change routine care or follow-up and uses data normally collected during clinical care.
Who should consider this trial
Good fit: Adults aged 18 to 70 who are candidates for or have undergone revision bariatric surgery with conversion to RYGB (post-ring, post-sleeve, or post-OAGB) and who consent to their data being used are the intended participants.
Not a fit: Pregnant patients, people unable to understand the information (for example due to dementia, psychosis, impaired consciousness, or language barriers), or patients not undergoing conversion to RYGB are unlikely to benefit from this comparison.
Why it matters
Potential benefit: If successful, the findings could help surgeons choose the surgical approach that reduces complications and improves recovery after revision conversion to RYGB.
How similar studies have performed: Previous comparisons of robotic and laparoscopic bariatric procedures have shown mixed results, with some reports suggesting advantages of robotics in complex revisions but no clear consensus across studies.
