Background:
Rapid weight loss after bariatric surgery is associated with a high prevalence of gallstone formation. In laparoscopic Roux-en-Y gastric bypass (RYGBP), the bypassed segment is not readily available for endoscopic or radiographic examination. We propose a laparoscopic Janeway gastrostomy for secondary access to excluded structures in bariatric centers with no mandatory technical equipment in endoscopic retrograde cholangiopancreatography (ERCP), double-balloon ERCP or spiral enteroscopy.
Method:
This was a single-institution retrospective review of a prospectively collected database of patients with a history of laparoscopic RYGBP who underwent laparoscopic Janeway gastrostomy for duodenal and biliary access. The operative indications, technical aspects, endoscopic findings, outcomes, and complications were investigated.
Results:
Five patients with a history of RYGBP underwent laparoscopic Janeway gastrostomy for exploration of the bypassed segment. All of them had biliary pathology, and all underwent successful ERCP and papillotomy. The gastrostomies were closed secondarily. The mean duration of hospitalization was 12 days. No complications developed. All procedures were performed laparoscopically.
Conclusion:
If access to excluded structures and simultaneous ERCP was not possible, temporary laparoscopic Janeway gastrostomy could be the last option alternative for a staged ERCP to gain access to the bypassed structures. It is a feasible and safe solution for the exploration and treatment of patients with a history of RYGBP in bariatric centers that have no endoscopists with expertise in ERCP.
