Systematic study of risk factors for biliary stone post-liver transplantation is rarely performed. To investigate the risk factor of choledocholithiasis formation after liver transplantation, we c onducted a case-control study. Fourteen patients were selected into a study group. The stones of the bile duct of the patients were confirmed and treated successfully by endoscopic retrograde cholangiopancreatography. For univariate analysis, we selected carefully some potential risk factors such as cold ischemia time, warm ischemia time, and biliary stricture. The results revealed that cold ischemia time and biliary stenosis were significant predictors. But multivariate analysis revealed that only biliary stenosis was a significant risk factor. In conclusion, biliary stenosis is a risk factor of bile duct stones formation after liver transplantation. Endoscopic retrograde cholangiopancreatography is effective and safe in the diagnosis or treatment of bile duct stones after liver transplantation.

BACKGROUND: Acute cholangitis varies from mild to severe form. Acute suppurative cholangitis (ASC), the severe form of acute cholangitis, is a fatal disease and requires urgent biliary decompression. Which patients are at a high risk of ASC and need emergency drainage is still unclear. The present study aimed to identify the factors for determining early-stage ASC and distinguishing ASC from acute cholangitis. METHODS: We analyzed 359 consecutive patients with acute cholangitis who had been admitted to the First Affiliated Hospital, Zhejiang University School of Medicine from January 2004 to May 2011. Emergency endoscopic retrograde cholangiopancreatography (ERCP) was carried out in all patients to decompress or clear the stones by experienced endoscopists Clinical and therapeutic data were collected, and univariate and multivariate analyses were performed to identify the potential risk factors of ASC. RESULTS: Of the 359 patients, 1 was excluded because of failure of ERCP drainage. Of the remaining 358 patients with an average age of 62.7 years (range 17-90), 162 were diagnosed with ASC, and 196 with non-ASC. ENBD catheters were placed in 343 patients (95.8%), of whom 182 patients had stones removed at the same time, and plastic stent was placed in 25 patients (7.0%) Clinical conditions were improved quickly after emergency biliary drainage in all patients. Complications were identified in 11 patients (3.1%): mild pancreatitis occurred in 8 patients and hemorrhage in 3 patients. There was no mortality. Univariate analysis showed that several variables were associated with ASC: age, fever, decreased urine output, hypotension, tachycardia abnormal white blood cell count (WBC), low platelet, high C reactive protein (CRP), and duration of the disease. Multivariateanalysis revealed that advanced age, hypotension, abnormal WBC, high CRP, and duration of the disease were independent risk factors for ASC. CONCLUSIONS: This study demonstrates that advanced age, hypotension,

BACKGROUND: Biliary complications are a serious problem in patients after liver transplantation and often require reoperation. This study was conducted to summarize the endoscopic diagnosis and management of biliary complications after orthotopic liver transplantation (OLT). METHODS: From December 2000 to November 2003, twelve endoscopic retrograde cholangiopancreatographies(ERCPs) were performed in 7 patients after OLT at Digestive Endoscopic Center of Changhai Hospital in Shanghai, China. The therapeutic maneuvers included endoscopic sphincterotomy (EST), biliary stent placement, balloon and basket extraction, irrigation, and nasobiliary tube placement. A retrospective study was made to determine the types of biliary tract complications after OLT. The success of ERCP and therapeutic maneuvers was also evaluated. RESULTS: Biliary tract complications including biliary stricture, biliary leak, biliary sludge, and stump leak of the cyst duct were treated respectively by endoscopic sphincterotomy with sludge extraction, stricture dilation or endoscopic retrograde biliary drainage. Two of the 3 patients with proximal common bile duct stricture were successfully treated with ERCP and stent placement. Four patients with anastomotic stricture and/without bile leak were treated successfully by dilation and stent placement or endoscopic nosobiliary drainage. No severe ERCP-related complications occurred. CONCLUSIONS: ERCP is an effective and accurate approach for the diagnosis of biliary tract complications after OLT, and placement of a stent is a safe initial treatment for biliary complications after liver transplantation.
