BACKGROUND:Endoscopic retrograde cholangiopancrea-tography(ERCP)is widely used to manage post-cholecystectomy bile ***,the best endoscopic intervention remains *** investigated the success of a 7 French double pigtail stent following sphincterotomy in the management of such bile leaks. METHODS:Between July 1998 and June 2008,48 patients were referred for ERCP for presumed post-cholecystectomy bile *** were confirmed at ERCP and managed by a combination of sphincterotomy and stent insertion unless contraindicated. RESULTS:Bile duct cannulation was successful in 44(91.7%)patients.A leak of the cystic duct was demonstrated in 19(43.2%)patients,the duct of Luschka in 11(25.0%),and the common hepatic duct in 5 (11.4%).Complete transection of the common bile duct occurred in 4 *** remaining patients had no cholangiographic evidence of a *** was performed in 34 patients.A 7 French double pigtail plastic stent was placed in all 35 patients with cholangiographic evidence of a bile *** bile leaks were demonstrated at a follow-up of 8-16 weeks and all stents were removed successfully. CONCLUSION:The combination of sphincterotomy and insertion of a 7 French double pigtail stent results in excellent outcomes in the management of post-cholecystectomy bile leaks.

BACKGROUND:Endoscopic therapy has been successful in the management of biliary complications after both deceased donor liver transplantation(DDLT) and living donor liver transplantation(LDLT).LDLT is thought to be associated with higher rates of biliary complications,but there are few studies comparing the success of endoscopic management of anastomotic strictures between the two *** study aims to compare our experience in the endoscopic management of anastomotic strictures in DDLT versus ***:This is a retrospective database review of all liver transplant patients undergoing endoscopic retrograde cholangiopancreatography(ERCP) after liver *** frequency of anastomotic stricture and the time to develop and to resolve anastomotic stricture were compared between DDLT and *** response of anastomotic stricture to endoscopic therapy was also ***:A total of 362 patients underwent liver transplantation between 2003 and 2011,with 125 requiring ERCP to manage biliary ***-three(9.9%) cases of DDLT and 8(27.6%) of LDLT(P=0.01) were found to have anastomotic *** comparing DDLT and LDLT,there was no difference in the mean time to the development of anastomotic strictures(98±17 vs 172±65 days,P=0.11),likelihood of response to ERCP [22(66.7%) vs 6(75.0%),P=0.69],mean time to the resolution of anastomotic strictures(268±77 vs 125±37 days,P=0.34),and the number of ERCPs required to achieve resolution(3.9±0.4 vs 4.7±0.9,P=0.38).CONCLUSIONS:Endoscopic therapy is effective in the majority of biliary complications relating to liver *** strictures occur more frequently in LDLT compared with DDLT,with equivalent endoscopic treatment response and outcomes for both groups.

为了用C_(22)和C_(26)直链和环烷烃的石油馏分油作原料制备适用于强化采油的活性剂,先将原料汽相氧化,再用碱液中和氧化产物。用红外光谱研究了氧化产物和中和产物的组成,发现前者含有羧酸,后者含有羧酸盐。得到的羧酸盐活性剂用于模拟油[由38.8%(体积)的异丙苯和61.2%(体积)的正癸烷组成],使油水间达到低于10^(-2)mN/cm的超低界面张力。实验表明,用氢氧化钠进行中和,比用其他的碱性物质(如硅酸钠、三聚磷酸钠、碳酸钠)更易得到界面活性高的活性剂溶液;当硅酸钠或三聚磷酸钠协同氢氧化钠一起与氧化产物反应时,所得活性剂的界面张力对电解质浓度的敏感程度比仅用氢氧化钠作处理剂时低,中和时的碱量会影响所得活性剂体系的界面张力。对于活性剂浓度不同的体系,若pH值相同则最佳含盐量也相同;若pH值高,则最佳含盐量低。当活性剂体系含有1000ppm的氯化钙时,仍具有良好的界面活性。在驱油试验中,浓度为1%的1个孔隙体积的活性剂溶液可采出42%的二次残油。
