Transcholecystic Duodenal Drainage as an Alternative Decompression Method for Afferent Loop Syndrome: Two Case Reports

초록

Afferent loop syndrome (ALS) is a rare complication of gastrectomies and gastrointestinal reconstruction. This can predispose patients to fatal conditions, such as cholangitis, pancreatitis, and duodenal perforation with peritonitis. Therefore, emergency decompression is necessary to prevent these complications. Herein, we report two cases in which transcholecystic duodenal drainage, an alternative decompression treatment, was performed in ALS patients without bile duct dilatation. Two patients who underwent distal gastrectomy with Billroth II anastomosis sought consultation in an emergency department for epigastric pain and vomiting. On CT, ALS with acute pancreatitis was diagnosed. However, biliary access could not be achieved because of the absence of bile duct dilatation. To overcome this problem, a duodenal drainage catheter was placed to decompress the afferent loop after traversing the cystic duct via a transcholecystic approach. The patients were discharged without additional surgical treatment 2 weeks and 1 month after drainage.
