Intragastric single-port surgery (IGS) accesses the gastric remnant and allows ERCP for common bile duct stones after RYGB: a simple solution for a difficult problem.

Abstract

BACKGROUND\nPatients who have undergone a Roux-en-Ygastric bypass (RYGB) and suffer from choledocholithiasis postoperatively pose a medical dilemma. Treatment of the cholestasis can be complicated because of the altered anatomy in these patients. The gastric remnant and duodenum are isolated from the pancreaticobiliary limb, making endoscopic retrograde pancreatography (ERCP) challenging and often impossible.\n\n\nOBJECTIVE\nTo describe a method for safe introduction of the endoscope into the gastric remnant through intragastric single-port surgery (IGS), thus allowing for simultaneous cholecystectomy.\n\n\nSETTING\nPilot clinical study.\n\n\nMETHODS\nThe present study is a nonrandomized clinical series describing our preliminary results using a transgastric inserted single-port device for ERCP after RYGB. The series includes 8 patients who underwent IGS ERCP after RYGB.\n\n\nRESULTS\nThe technique was successfully applied for intraoperative ERCP through a transgastric inserted single-port device (Gelpoint Mini, Applied Medical, Rancho Santa Margarita, CA). Papilotomy was easily achieved without complications. Average operative time was 144.75 minutes. The patients recovered without complications and could be discharged after a mean of 4.38 days.\n\n\nCONCLUSIONS\nThe novel IGS technique is safe and effective and can be applied to perform ERCP in patients with RYGB anatomy. Transgastric single port ERCP was simple to perform, achieved excellent results, and allowed for endoscopic treatment and cholecystectomy to be performed in a single procedure. The technique can be indicated in patients with complicated gallstone obstruction under altered anatomy after RYGB.
