Novel case of percutaneous access of afferent limb of Roux-en-Y hepaticojejunostomy for biliary decompression and jejunoplasty in a patient with primary sclerosing cholangitis
Abstract
Primary sclerosing cholangitis is a rare condition characterized by multifocal fibrotic bile duct strictures and progressive liver disease. Due to its recurrence even after liver transplantation, an alternative surgical procedure, the Roux-en-Y hepaticojejunostomy, is practiced with positive outcomes. We present a case of a 55-year-old female with history of primary sclerosing cholangitis and Roux-en-Y hepaticojejunostomy approximately 25 years ago who presented to the emergency department with acute cholangitis. Computed tomography of the abdomen revealed a dilated loop of small bowel in the right upper quadrant and mid-abdomen with normal bile duct caliber. Interventional radiology was consulted for percutaneous biliary and Roux limb decompression. Ultrasound was utilized to identify and percutaneously access the dilated afferent jejunal limb. With the help of a T-fastener, the jejunal loop was tacked against the anterior abdominal wall and the system was successfully decompressed with a drain left in place. On follow-up, delayed contrast transit through the Roux limb and a stricture in the native jejunum distal to the anastomosis was identified. Hampering of the downstream flow of bile was noted and this was determined to be the likely cause of the initial episode of cholangitis. The strictured bowel segment was balloon-dilated by interventional radiology. Repeat injection of contrast revealed significant improvement in the caliber of the stenotic segment. At 3 weeks' postprocedure, a follow-up enteroscopy of the bowel was performed through the same percutaneous access site. Using this technique, the patient avoided a major invasive surgical procedure.
