Magnetic-Assisted 9-Step Surgery to Convert Sleeve Gastrectomy to Roux-en-Y Gastric Bypass with Hiatoplasty Using Single-Port Technique

What this Trial Is About

Researchers are evaluating a magnetic-assisted surgical technique for revisional bariatric surgery, specifically converting sleeve gastrectomy to Roux-en-Y gastric bypass RYGB combined with hiatoplasty. This approach addresses long-term problems such as gastroesophageal reflux disease GERD in patients who have undergone laparoscopic gastric sleeve LGS surgery. The study aims to assess the surgical procedure and its outcomes in patients who are candidates for bariatric surgery with obesity. The surgery is performed using magnetic assistance to improve visualization and manipulation during key steps. It involves placing a single port in the umbilicus and an additional trocar, using magnets for liver retraction, dividing the omentum, repairing hiatal hernia, creating the gastric pouch, measuring and connecting intestinal limbs, and closing defects. A methylene blue leak test is done to check for leaks, and the entire Roux-en-Y gastric bypass is completed with magnet-assisted maneuvers. Participants undergo this bariatric procedure with magnetic assistance and are monitored for complications within 30 days, device malfunction within 1-2 hours post-procedure, and surgical time within 30 days. The study includes evaluations of surgical field exposure, anastomosis construction, and hernia repair. The total participation timeline includes the surgical procedure and follow-up assessments up to 30 days after surgery.
