Objective To evaluate the treatment and prevention measure for intrahepatie diffuse biliary stricture after orthotopic liver transplantation. Methods The clinical data of 21 patients with intrahepatic diffuse biliary stricture after orthotopic liver transplantation from January 2002 to December 2007 in Beijing Center for Organ Transplantation were retrospectively analyzed. A prospective clinic study was launched in order to prevent microthrombosis in the microcireulation of bile duct during warm and cold iscbemia in non-heart-beating donor since January 2006. Urokinase perfusion of the artery system was conducted during graft harvesting and reperfusion at the end of graft trimming to reduce the incidence of intrahepatic diffuse biliary stricture. Results Among 21 patients with intrahepatie diffuse and mixed type biliary stricture, 16 patients underwent liver retransplantation, and the other 5 patients died of primary graft failure while waiting for retransplantation. The incidence of intrahepatic diffuse biiiary stricture was 5.9% in non-urokinase perfusion group. On the contrary, the incidence rate of intrahepatie diffuse biliary stricture was 1.4% in urokinase perfusian group (x2 = 5.98, P < 0. 05). Conclusions Liver retransplantation is effective for refractory biliary stricture in liver transplant recipients. The incidence of intrahepatic diffuse biliary stricture is reduced in non-heart-beating donor by using urokinase perfusian.

Objective To summarize the experience of emergency orthotopic liver transplantation (EOLT) in fulminant hepatic failure (FHF).Methods The clinical date of 4 cases of FHF successfully subject to EOLT were retrospectively analyzed.Results Four patients’ consciousness completely recovered in 12 to 48 h after operation, no surgical complication occurred; Acute rejection postoperatively occurred in 2 patients and reversed after treatment. Now 4 patients were survived for 38, 17, 11, 7 months respectively with good liver function, and 3 of them went to work again.Conclusion EOLT is an effective means to cure FHF. Choosing appropriate perioperative management and (operative) timing is essential to improve the successful rate of EOLT.

OBJECTIVE To analyze the characteristic of vancomycin-resistant Enterococcus(VRE) infection after orthotopic liver transplantation, and provide a basis to improve prophylaxis and therapy. METHODS A retrospective survey in 136 patients who underwent orthotopic liver transplantation was carried out to define the incidence, clinical feature and therapeutic outcome of VRE infection. RESULTS Eleven patients were infected by VRE in this study and the incidence of infection by VRE was 8.1% following liver transplantation. Totally 31 of the VRE isolates were isolated, including 26 Enterococcus faecium strains and 5 E. faecalis strains. Sites of VRE infection included abdomen(n=4), blood(n=2), and respiratory tract(n=2). In the other 3 patients, VRE was cultured from multiple sites. Among 11 patients with VRE infection, 4 were sensitive to teicoplanin, and 7 resistant to teicoplanin. So 4 patients received antibiotics with teicoplanin and 7 patients with linezolid. In this study, 10 patients were cured and 1 patient died of sepsis. CONCLUSIONS VRE has become an nosocomial pathogen of increasing importance in liver transplantation patients. The risk factor of VRE infection should be paid attention. Infection prophylaxis of VRE should be emphasized.

Fifteen journals related with liver diseases were selected from Chinese science and technology journal citation reports ( core ) ( CJCR ) during 2004 - 2009.Eleven important quantitative indicators including total cited frequency and impact factor were analyzed.At the same time,the dynamic evaluation model was also used to evaluate the academic influence of the 15 kinds of liver diseases journals.There were 5 kinds of trends:always arising,spiral arising,stabilizing after adjusting,vibrating highly and adjusting.The academic influence of liver diseases journals was rather high,but there were some problems including low academic influence,low ratio of funded papers and international papers and poor paper quality.

Objective To discuss the feature of transient intrahepatic cholestasis in early stage of orthotopic liver transplantation. Methods Based on the review of early (within 1 month) postoperative hyperbilirubinemia in consecutive 200 patients undergoing liver transplantation, we summarized the occurrence, development and outcome of early postoperative intrahepatic cholestasis. Results Early transient intrahepatic cholestasis was identified in 112 patients. The characteristic of early intrahepatic cholestasis is that DBIL and?-GT increasingly elevated from the second or third day postoperatively, with a peak on the 7 - 14th d, then descended to normal level on approximately 21 -28th day. The average peak level of DBIL and?-GT were( 157. 32?82. 08)?mol/L and (172?80) IU/L respectively. During the period of DBIL and?-GT ascending, AST and ALT kept descending, and within 1 week it could fall to normal level. Acute rejection, drug toxicosis and bile duct obstruction were excluded. Conclusions Postoperative early transient intrahepatic cholestasis associated with ischemia-reperfusion injury has its special clinical process and most patients recover themselves without the need for special therapy.

Medical ethics is correlated with further development of affiliated teaching hospital.Our hospital took ‘ Bethune spirit’ and philosophy of forgiveness and kindheartedness as guidance and became the first batch of Bethune spirit model hospital of Chongqing.Teaching quality was improved by providing lectures about ‘ Bethune spirit’ for medical students and equally emphasizing medical knowledge and medical ethics education.Anti-corruption and academy governing movements with the subject of ‘ Bethune spirit’ were carried out to repel academic misdeed,with the result that clinical,teaching and scientific works were promoted and advanced.

Objective To probe the indication of biliary tract reconstruction without T-tube in orthotopic liver transplantation.Methods We put forward indications of biliary tract reconstruction without T-tube in orthotopic liver transplantation since January 2004 and there were 102 patients who underwent liver transplantation in our hospital without a T-tube in place after biliary tract reconstruction.The incidence of biliary tract complication was observed in these patients.Results All patients were followed up for more than 6 months.The incidence of biliary tract complication was 4.9 percent(5/102)in this group with 3 patients of intrahepatic difluse bile duct stenosis necessitating liver re-transplantation.The other 2 patients with common hepatic duct nonanastomotic stenosis were healed by ERCP plus stent placement.Conclusions Biliary tract reconstruction without T-tube placement helps to decrease the incidence of biliary tract complications resulting from the T-tube removal.

Objective To study the clinical characteristics which are related to malignancy in pancreatic intraductal papillary mucinous neoplasm (IPMN) with an aim to provide evidence for clinical practice.Methods Using PubMed,all pancreatic IPMN related articles with positive pathologic results before July 30th,2011 were studied.A pooled analysis was carried out on the morphological features of the disease.The analysis included gender,diameter of main pancreatic duct,diameter of cystic lesion,mural nodules and histological types (benign/malignant) of the neoplasm.Results 98 articles (including 1902 cases) were collected and analyzed.1025 cases were benign (53.89％) and 877 cases (46.11 ％) were malignant.Morphologically,there were a correlation between main pancreatic duct dilatation (≥5 mm),cystic lesion of large size (≥30 mm),presence of mural nodules and malignancy.The OR (95％ CI) were 5.591 (3.657-8.548),3.633 (2.626-5.027) and 4.983 (3.872-6.412) respectively.Conclusions A main pancreatic duct dilatation (≥5 mm),cystic lesions of large size (≥30 mm) and presence of mural nodules prompt the tumor to be malignant.In clinical work,the management of pancreatic IPMN should be made prudently based on comprehensive analysis of clinical features and the patient's status and intent.
