title: [Two cases of catheter tip dislocation to the duodenal bulb: a rare complication of hepatic arterial infusion chemotherapy].
abstract: Case 1: A 63-year-old woman underwent transverse colectomy and hepatectomy for colonic cancer and liver metastasis. A hepatic arterial infusion port (HAIP) was implanted. Continuous infusion of 5-FU (total amount, 7,500 mg) caused a hemorrhagic duodenal ulcer 15 months after. Follow-up endoscopy revealed the catheter tip was in the duodenal bulb. Case 2: A 62-year-old man underwent abdominoperineal resection for rectal cancer. Repeated hepatectomy for liver metastases was performed at 3 and 5 years after the first operation. HAIP was implanted at the last operation, but was not available at all due to the wound infection. The port was removed, but the catheter remained. Three years after, the catheter tip was found in the duodenal bulb by endoscopy.
