Serious complications have occurred in a considerable proportion of living donors of liver transplants, but data from a single high-volume center has rarely been available. We analyzed the medical records of donors and recipients of the first 1,000 living donor liver transplants, performed at Asan Medical Center from December 1994 to June 2005, with a focus on donor safety. There were 107 pediatric and 893 adult transplants. The most common diagnoses were biliary atresia in pediatric recipients (63%) and hepatitis B-associated liver cirrhosis (80%) in adult recipients. Right lobe donors were strictly selected based on liver resection rate and steatosis. From 1,162 living donors, 588 right lobes, 6 extended right lobes, 7 right posterior segments, 464 left lobes, and 107 left lateral segments were obtained. Of these, 837 grafts were implanted singly, whereas 325, along with 1 cadaveric split graft, were implanted as dual grafts into 163 recipients. The 5-yr survival rates were 84.8% in pediatric recipients and 83.2% in adult recipients. There was no donor mortality, but 3.2% of donors experienced major complications. Until the end of 2001, the major donor complication rate was 6.7%, with most occurring in right liver donors. Since 2002, liver resection exceeding 65% of whole liver volume were avoided except for young donors with no hepatic steatosis, and the donor complication rate has been reduced to 1.3%. In conclusion, a majority of major living donor complications appear to be avoidable through the strict selection of living donor and graft type, intensive postoperative surveillance, and timely feedback of surgical techniques. Selection of right lobe graft should be very prudently considered if the donor right liver appears to be larger than 65% of the whole liver volume. Liver Transpl 12: 920-927, 2006.

Background/purpose Both curative resection and minimized in-hospital mortality offer the only chance of longterm survival in patients with hilar cholangiocarcinoma. The reported resectability rates for hilar cholangiocarcinoma have increased by virtue of combined major hepatectomy, but this procedure is technically demanding and still associated with a significant morbidity and mortality that must be carefully balanced against the chances of longterm survival. Methods Between January 2001 and December 2008, 350 patients with hilar cholangiocarcinoma underwent exploration for the purpose of potentially curative resection, of whom 302 (86.3%) were resected in the Department of Hepato-Biliary Surgery and Liver Transplantation, Asan Medical Center, University of Ulsan College of Medicine. Combined hepatectomy was carried out in 268 (88.7%) of 302 resected patients. Major hemihepatectomy and parenchyma-preserving hepatectomy were performed in 257 and 11 patients, respectively. Portal vein resection was associated in 40 (14.9%) of 268 hepatectomized patients.To control preoperative cholangitis and reduce risk of postoperative hepatic failure, biliary decompression through endoscopic and/or percutaneous transhepatic drainage and portal vein embolization were preoperatively applied in 329 (94.0%) of 350 explored patients and in 91 (54.2%) of 168 extended hepatectomized patients (154 right hemihepatectomy, 9 right trisectionectomy, 5 left trisectionectomy), respectively. Liver transplantation was not performed as primary treatment for hilar cholangiocarcinoma. Results There were 5 cases (1.7%) of in-hospital death after resection and 1 postoperative liver failure that was successfully treated with liver transplantation. Major complications were encountered in 23 patients (7.0%), and the overall morbidity rate was 43%. In 302 resections, 214 (70.9%) were curative resections (R0) and 88 (29.1%) were palliative resections (R1). The overall 1-, 3-and 5-year survival rates after resection, including in-hospital deaths, were 84.6, 50.7 and 47.3% in the R0 group and 69.9, 33.3 and 7.5% in the R1 group, respectively. The 5-year survival rate of extended hemihepatectomy of 36.4% was better than that of parenchyma-preserving hepatectomy at 10.5%. Two significant predictive factors adversely affecting survival after resection were lymph node metastasis and incurability of surgery (P \ 0.001). Two patients with vascular involvement who underwent concomitant hepatic artery and portal vein reconstruction are alive after more than 3 years. Conclusion Preoperative biliary decompression and portal vein embolization enabled us to reduce in-hospital deaths associated with extended hepatectomy for hilar cholangiocarcinoma. Major hemihepatectomy offers an increased survival because of the higher possibility of curative resection than bile duct resection alone and parenchyma-preserving hepatectomy, but it still carries a certain mortality.

Covered expandable metallic stents were placed in 61 patients with ERFs, but the initial clinical success rate was poor and the rate of reopening was high; however, interventional treatment was effective for sealing off reopened ERFs.

Treatment with placement of a covered expandable stent tube is effective in most patients with dysphagia due to malignant esophogastric strictures and is less effective in patients with benign strictures.

Vascular plug-assisted RTO is technically simple and safe and seems to be clinically effective for treatment of GV and HE.
