Intracholedochal irrigation with saline through a nasobiliary catheter: an adjunct to endoscopic sphincterotomy in the treatment of large stones in the common bile duct.

A 54-year-old woman with multiple abdominal operations including cholecystectomy and partial small bowel resection was admitted to the hospital because of pain in the right upper quadrant. Multiple common bile duct stones-the largest one measuring approximately 2 cm-were seen during endoscopic retrograde cholangiogram. The patient was successfully treated with endoscopic sphincterotomy and placement of a nasobiliary catheter for intracholedochal irrigation with a saline solution.
