Background: The technique of biliary reconstruction remains controversial in living-donor liver transplantation (LDLT). The objective of this study was to assess the incidence of biliary complications after LDLT based on the reconstruction technique. Methods: Between 1997 and 2007, 30 patients underwent LDLT. The type of allograft was the right lobe in 15, left lobe in 4 and left lateral sector in 11 patients. There were 18 adult and 12 paediatric recipients. The mean follow-up was 48 months (range 18-120 months). Biliary complications were defined as leak or stricture requiring intervention. Results: Biliary reconstruction was achieved with Roux-en-Y choledochojejunostomy (RYCJ) in 17 patients and duct-to-duct (DD) anastomosis in 13 patients. An external biliary stent was placed in all patients (except one) in the RYCJ group and reconstruction over a T-tube was done in 6 out of 13 patients in the DD Group. Twenty-five (83.3%) patients had one biliary anastomosis and the remaining five (16.7%) had multiple anastomoses (one in the RYCJ group and four in the DD group). The overall incidence of biliary complications was 30%.; 29.4% in the RYCJ group and 38.4% in the DD group (P = 0.6). Biliary complications occurred equally in patients with and without an external stent or T-tube stenting (12.5% vs. 18.8%). The incidence of biliary leakage was 23.5% for RYCJ and 15.3% for DD (P = 0.4). Although the incidence of biliary stricture was significantly higher in the DD (23.1%) compared with the RYCY group (5.9 %) (P < 0.01), all DDCC strictures were successfully managed endoscopically. Need for operative revision of biliary anastomoses was significantly higher in patients with RYCY compared with DD reconstruction; 17.7% vs. 7.7% (P < 0.01). Conclusions: Although there was a higher rate of biliary stricture formation in the DDCC group, we feel that because of physiological bilioenteric continuity, comparable incidence of leakage and easy endoscopic access, DD reconstruction is the preferred approach for biliary drainage in LDLT. After LDLT, the endoscopic approach has been shown to provide effective treatment of most biliary complications.
Biliary reconstruction and complications in living donor liver transplantation

For a technically successful liver transplant (LT), secure bile duct anastomosis to prevent biliary complications (BC's) like biliary anastomotic stricture (BAS) and bile leak (BL) is mandatory. BC's after living donor liver transplantation (LDLT) are relatively more common compared to deceased donor LT (DDLT), particularly owing to surgical factors (small diameter, and/or multiple bile duct openings on the graft), and non-surgical factors (immunologic reactions). Adequate blood supply to the bile duct both in donor and recipient, meticulous anastomotic technique, mucosal eversion for better approximation thus avoiding lesser fibrosis, proper use of internal or external stent drainage, and tension-free anastomosis, may contribute to the decrease of BC's after LDLT. Further, if BC's are not dealt with in a timely manner, these could progressively lead to severe morbidities and even mortality. While the endoscopic approach is preferred initially to deal with biliary leaks or strictures, the more invasive percutaneous approach may be required in case of endoscopic failure. Dedicated and experienced endoscopists, and interventional radiologists are key members of the multidisciplinary team in a successful LDLT program. In this review, we have tried to summarize current concepts in surgical techniques of biliary reconstruction in LDLT, incidence and risk factors for BC's, and principles followed to try and reduce the incidence of the same.

Objective. Biliary complications remain a major source of morbidity after living donor liver transplantation (LDLT). Of 109 consecutive right lobe (RL)-LDLTs performed in 1 year in our institution, we present the biliary complications among 106 patients who underwent a new duct-to-duct anastomosis technique known as University of Inonu. Methods. Of 153 liver transplantations performed in 1 year from January to December of 2008, 128 were LDLTs including 109 RL-LDLTs. The others were left or left lateral grafts. All RL-LDLT patients were adults, all of whom except three included a duct-toduct anastomosis. Results. All, but three, biliary reconstructions were completed with a surgical technique, so called UI, in which 6-0 prolene sutures were used. Nine bile leaks were seen in 106 recipients (8.49%) performed in a duct-to-duct fashion in a time period of 1 to 4 weeks. Seventeen patients (16.03%) posed bile duct stricture (BDS). Five patients had both. Although endoscopic stent placement and percutaneous balloon dilatation, 4 patients continued to suffer from BDS on whom a permanent access hepatico-jejunostomy (PAHJ) procedures were performed. Conclusion. We recommend a duct-to-duct biliary reconstruction because of its de facto advantages over other types of anastomosis provided the native duct is not diseased. After almost 2 years, the bile tract complication rate was 22.64%.
Results of Biliary Reconstructions in Liver Transplantation at Our Center

Biliary complications are some of the most critical problems in liver transplantation. Despite various refinements in surgical technique, different types of liver transplantations are associated with significant numbers of biliary problems. In this study, we analyzed the results of biliary reconstructions in 127 liver transplant recipients at our center from April 2001 to May 2006. Through November 2004, we used different techniques for biliary reconstruction in 66 of these patients, including duct-to-duct (DD) anastomoses, Roux-en-Y hepaticojejunostomy (RYHJ), anastomoses over T tubes or stents, and anastomoses without stenting. During the first period, we used a DD anastomosis in 15 cadaveric whole liver grafts and in 25 right lobe and 12 left lobe or left lateral segment grafts from living-related donors. RYHJ was preferred in 2 cadaveric and 12 left lateral segment grafts. Beginning in November 2004, we employed intraoperative transhepatic biliary catheter insertion in 61 patients (29 children, 32 adults). In the most recent 61 cases of 13 liver grafts from cadavers and 48 from living-related donors, 14 patients (2 children and 12 adults) received whole-liver grafts, 22 (all adults) a right lobe, and 26 (all children) a left lateral or left lobe. Intraoperative transhepatic biliary catheter insertion was performed with DD anastomosis in 55 cases and with RYHJ in 6 cases. The mean complication rate decreased from 24% to 8.1% during the period using a new biliary reconstruction technique. Five biliary complications occurred in four patients. The new technique of biliary reconstruction using intraoperative biliary catheter insertion has significantly reduced the biliary complication rate. Transhepatic biliary stenting prevents biliary complications and maintains percutaneous access when problems arise. Intraoperative transhepatic biliary catheter insertion at the back table is a safe way to provide good biliary drainage after liver transplantation.

Backgroud: A biliary stricture is the most common complication after living-donor liver transplantation (LDLT). The present study was performed to examine treatment methods and outcomes after treatment for a biliary stricture after LDLT. Methods and Results: From January 2000 to December 2010, 488 patients underwent LDLT using the right lobe with duct-to-duct anastomosis at our transplantation centre. Overall biliary strictures were detected in 160 patients (32.8%), and the majority occurred within 2 years after LDLT. Biliary strictures were related to bile leakage (P < 0.001) and the urgency of the surgery (P = 0.012) in a multivariate analysis. All biliary strictures were treated with interventional modalities including an endoscopic or a percutaneous approach. Failure of interventional treatment was demonstrated in 13 patients (8.5%), among them, four (2.6%) underwent re-transplantation and nine (5.9%) died of sepsis and biliary cirrhosis during the follow-up period. A biliary stricture was not related to the survival rate (P = 0.586). Conclusion: The incidence of overall biliary stricture was related to bile leakage and the urgency of the surgery. All biliary strictures could be treated by interventional modalities. These approaches are effective, complementary and help to avoid the need for surgery for a biliary stricture.

Biliary complications are known as a weak point of liver transplantation. Their occurence can be related to the practice of draining the biliary anastomosis performed at the time of transplantation. At our institution, routine of anastomotic biliary drainage was abandoned in June 2004. Aim. We sought to assess the occurence and character of biliary complications following orthotopic liver transplantation in relation to the technique of anastomosis. Materials and Methods. In two groups of transplantees: last 100 transplantations with biliary drainage (48 females and 52 males aged 17 to 64 years) and last 100 transplantations without drainage (52 females and 48 males aged 18 to 67 years). The results of treatment were compared, for biliary complications and their influence on further management. In both groups, the main indications for transplantation were various types of cirrhosis as well as cholestatic diseases. In most cases (167) we performed a cholangiojejunal Roux-en-Y (CBD) end-to-end anastomosis, less commonly (33 cases) hepaticojejunal anstomoses. Results. In the first group, biliary complications (bile leak at the site of drainage, bile leak after T-tube removal, CBD strictures) requiring surgical or endoscopic intervention, occurred in 17% recipients. In one case, the biliary complication resulted in retransplantation. In the second group, biliary complications occured in 11% patients. None of them caused organ loss. Conclusion. Abandoning drainage of the biliary anastomosis has reduced the occurrence of early biliary complications after orthotopic liver transplantation.
