담관 낭종 절제 후 발생한 문합부 협착을 자석 압박 문합술로 치료한 1예

Abstract

Magnet compression anastomosis is a nonsurgical method that uses two magnets to treat bilio-biliary and bilio-enteric anastomotic strictures after a living donor transplantation. The compression pressure of the two magnets induces ischemic necrosis at the anastomostic stricture and creates a fistula at the stricture site. A choledochal cyst is an uncommon congenital anomaly characterized by dilatation of the biliary tree and can cause obstructive jaundice, cholangitis, biliary stones, and cholangiocelluar carcinoma. Treatment for choledochal cyst is essentially surgical including total excision of the cyst with hepaticoenterostomy, but there can be complications such as postoperative intrahepatic stones and recurrent cholangitis due to a stricture at the site of the anastomosis. Endoscopic and fluoroscopy-guided radiologic interventions can be applied to resolve the anastomotic stricture, and re-operation is possible as the method of last resort. We report here a first case, trial magnet compression anastomosis in Korea of a bilioenteric anastomotic stricture after excision of a choledochal cyst and hepaticojejunostomy.
