A Case of Recurrent Liver Abscess Due to Choledochoduodenal Fistula

재발하는 간농양에서 총담관-십이지장 누공의 내시경적 치료 1예

Cholelithiasis, duodenal ulcer, duodenal perforation and tumor invasion may lead to choledochoduodenal fistula (CDF). CDF often has no specific symptoms and may be incidentally detected in an upper gastrointestinal radiographic study or endoscopy; but in some cases, it may be accompanied by recurrent cholangitis and liver abscess. In this paper, a case of recurrent liver abscess caused by CDF is reported. A 62-year-old female was admitted to the authors' hospital because of right upper quadrant pain and fever. The abdominal computed tomography showed a liver abscess in the right lobe. A duodenal fistulous orifice was detected with endoscopy, and a contrast was injected through the duodenal orifice using a catheter under fluoroscopy. The injection of the contrast revealed a fistulous track between the duodenal bulb and the common hepatic duct. In fistulas complicated by recurrent liver abscess, surgery or medical management may be needed. The CDF in this case study was treated via endoscopic clipping.
