Abstract
BACKGROUND Endoscopic retrograde cholangiopancreatography for common bile duct stone in patients who underwent gastrectomy and Roux-en-Y anastomosis is challenging. We report a case in which we performed endoscopic retrograde cholangiopancreatography through a small-intestinal incision approach for a common bile duct stone, which had developed after total gastrectomy and Roux-en-Y anastomosis. CASE REPORT An 86-year-old woman with a history of laparoscopic-assisted total gastrectomy and R-Y anastomosis and incision of the common bile duct and cholecystectomy for common bile duct stone by open surgery 3 years ago presented with abdominal pain. Examination revealed a 10-mm stone in the lower part of common bile duct. We planned a combined endoscopic and open surgical approach. An incision on the Y limb of the Roux-en-Y anastomosis 20 cm from the jejunojejunal anastomosis and insertion of an endoscope through this opening were performed to extract the common bile duct stone. The patient was discharged on postoperative day 22 without complications. CONCLUSIONS For a patient with a common bile duct stone, who underwent gastrectomy and Roux-en-Y anastomosis, with firm adhesions at the porta hepatis, combined endoscopy and open surgery using a small-intestinal incision approach can be effective when small-bowel endoscopes are unavailable or the cannulation to Vater's papilla by them is difficult.
