Biliary tract reconstruction in liver transplantation

Successful Treatment of Stricture of Duct-to-Duct Biliary Anastomosis After Living-Donor Liver Transplantation of the Left Lobe: A Case Report

Biliary complications, such as stricture or obstruction, after living-donor liver transplantation (LDLT) remain major problems to be solved. Magnetic compression anastomosis (MCA) is a minimally invasive method of biliary anastomosis without surgery in patients with biliary stricture or obstruction. A 66-year-old woman had undergone LDLT for end-stage liver disease for primary biliary cholangitis 20 months previously at another hospital. Computerized tomography showed dilation of the intrahepatic bile duct (B2). Because B2 was invisible with the use of endoscopic retrograde cholangiopancreatography, percutaneous transhepatic biliary drainage (PTBD) was performed for treatment of cholangitis. The rendezvous technique failed because a guidewire could not pass through the biliary stricture. Therefore, we decided to perform MCA. A parent magnet was endoscopically placed distally in the common bile duct of the stricture, and a daughter magnet attached to a guidewire was inserted proximally through the fistula tract of the PTBD. Both magnets were positioned across the stricture, and the 2 magnets were pulled to each other by magnetic power, to sandwich the stricture. By 14 days after MCA, a fistula between B2 and the common bile duct was created. At 28 days after MCA, the magnets were removed distally and a 16-French tube was placed across the fistula. At 7 months after MCA, that tube was removed. In conclusion, when a conventional endoscopic or percutaneous approach including the rendezvous technique fails, MCA is a good technique for biliary stricture after LDLT.

Cholecystectomy due to symptomatic gallbladder disease after orthotopic liver transplantation: report of three cases

Although biliary stones and sludge are relatively common after liver transplantation (OLT), symptomatic cholecystolithiasis or acute cholecystitis have rarely been reported. Until the early 1990s few transplant centers preserved the donor's gallbladder for transplantation with the liver graft. This technique allows one to perform procedures, such as cholecystojejunostomy or a donor gallbladder conduit for biliary tract reconstruction, to treat posttransplant biliary complications. Herein we have reported three cases of successful either laparoscopic or open cholecystectomy for symptomatic cholecystolithiasis or acute cholecystitis between 14 and 19 years after OLT, as well as a systematic literature review.

Interventional radiology: management of biliary complications of liver transplantation

Major advances in the field of liver transplantation have led to an increase in both graft and patient survival rates. Despite increased graft survival rate, biliary complications lead to significant postoperative morbidity and even mortality. A multidisciplinary approach to these complications is critical. As part of the team approach, less invasive techniques used by the interventional radiologist have an increasing role in the management of complications after liver transplantation. This paper will review the current role of the interventionalist in management of biliary complications.

Biliary complications in recipients of living-donor liver transplantation

The key points of the management of biliary complications in recipients of living-donor liver transplantation are described. The characteristics of these complications are somewhat different from those in deceased-donor liver transplantation, mainly due to the technical difficulties. Appropriate prevention, diagnosis, and treatment are essential for successful transplants, to avoid the development of secondary biliary cirrhosis when complication occurs.

Duct-to-duct biliary reconstruction in adult-to-adult living donor liver transplantation

In living donor liver transplantation (LDLT), Roux-en-Y hepaticojejunostomy has been a standard technique for biliary reconstruction because the majority had been pediatric patients with biliary atresia. Adult-to-adult LDLT using the right lobe graft has recently been developed and we introduced duct-to-duct biliary reconstruction (hepaticohepaticostomy) in such cases. The aim of this study is to evaluate the feasibility of this procedure in adult-to-adult LDLT. From August 2000 to October 2001, five patients underwent adult-to-adult LDLT using the right hepatic lobe and were followed for more than 6 months at our institution. All patients underwent duct-to-duct biliary reconstruction (single hepaticohepaticostomy in one, multiple in four). For the grafts with multiple bile ducts, various techniques were used for reconstruction. In all patients, oral intake could be started early after the operation, and biliary leakage was not encountered. One patient developed two episodes of acute cholangitis who later developed biliary anastomosis stricture which required percutaneous dilatation at 11 months postop. However, otherwise, there were no infectious complications postoperatively. We conclude duct-to-duct biliary reconstruction is feasible and effective in adult-to-adult LDLT.
