Biliary complications after 52 adult living donor liver transplantations: a single-center experience.

OBJECTIVE: The incidence of biliary complications after adult living donor liver transplantation (ALDLT) are still high even though various devices have been reported to overcome them. METHOD: From October 2000 to April 2007, we performed 52 ALDLTs which included 15 ABO-incompatible grafts. Median follow-up was 565 days. In 49 procedures, we used duct-to-duct anastmosis with a stent inserted in the recipient duct and out through the common bile duct wall as an external stent, and in 3 procedures, we used duct-to-jejunostomy anastomosis. We investigated postoperative biliary complications and their management. RESULTS: Forty-four patients received right lobe grafts and 8 received left lobe grafts. Among patients in whom duct-to-duct anastomosis was used, nine (20.5%) developed biliary complications including bile leakage in five and biliary strictures in four. All bile leakage was treated with reoperation. Three biliary strictures were treated with stent placement, and one biliary stricture was treated with magnetic compression anastomosis. Among the three patients in whom duct-to-jejunostomy was used, two (66.7%) had bile leakage and stricture, respectively. Two of four ABO-incompatible patients (50%) had hepatic artery thrombosis with biliary complications, a high incidence. CONCLUSION: In our series of ABO-incompatible patients undergoing ALDLT, those who developed hepatic artery thrombosis exhibited a high incidence of biliary complications.

[A case of AFP producing early gastric cancer successfully treated with small dose CDDP and 5-FU (PF) therapy].

A case of AFP producing early gastric cancer successfully treated with a small dose of CDDP and 5-FU therapy administered intermittedly is reported with a review of the literature. A 63-year-old male was admitted to our hospital because of liver metastasis with a high level of serum AFP (185.8 ng/ml) three months after gastrectomy. Systemic chemotherapy was performed twice with a regimen of CDDP 20 mg and 5-FU 750 mg/day in 5 days. After hepatic arterial infusion chemotherapy (HAIC) was performed once, the patient obtained partial response according to CT scan and was discharged. After he underwent HAIC once as an outpatient, liver metastasis completely disappeared 5 months after surgery. He was administered oral 5-FU, 150 mg and Krestin 3.0 g/day and underwent HAIC with CDDP 20 mg and 5-FU 750 mg/day every 2 weeks. After serum AFP level was returned to the normal range 7 months after surgery; HAIC was performed every 4 weeks and continued until one year after surgery. One year and 11 months after surgery, serum AFP remains within the normal limit and there is no evidence of recurrence.

[Study of transforming growth factor-alpha expression in duodenal ulcer].

Various growth factors were also reported to promote healing of peptic ulcer. We have used a monoclonal antibody in conjunction with a standard immunohistochemical technique to characterize the expression of transforming growth factor-alpha (TGF-alpha) in duodenal ulcer. TGF-alpha immunoreactivity is found in Brunner's gland, also in immature gland and in duodenal epitheliums, but not in gastric metaplasia of the duodenum. TGF-alpha expression of healing and scar stage was higher than that of active stage. The presence or absence of Helicobacter pylori infection did not affect the expression of TGF-alpha in duodenal ulcer.
