Surgical Complications and Long-Term Outcome of Different Biliary Reconstructions in Liver Transplantation for Primary Sclerosing Cholangitis—Choledochoduodenostomy versus Choledochojejunostomy

Choledochojejunostomy (CJS) is commonly used for biliary reconstruction in liver transplantation for primary sclerosing cholangitis (PSC). We alternatively performed choledochoduodenostomy (CDS) and side-to-side choledochodocholedochstomy in a large cohort of patients. Fifty-one patients with PSC, transplanted between 1988 and 2000, were analyzed retrospectively. Biliary reconstruction was CDS in 25 (49%), CJS in 20 (39%) and CC in 6 transplantations (12%). Biliary leaks occurred in the early follow-up (< or =41 days) only in CDS patients (20%). However, in the late follow-up (>4 months), stricturing of anastomosis was found once in CDS (4%) and CJS (5%). Later (>9 months), intrahepatic bile duct strictures were diagnosed in four CDS (16%), one CJS (5%) and one CC (17%) patient(s). In 48% of CDS (12/25), 60% of CJS (12/20) and 17% of CC (1/6) at least one incidence of cholangitis was observed. Overall, biliary complication rates were significantly higher in CDS (40%) than CJS (10%) and CC (17%); of those none in CC and 12% in CDS were anastomosis-related. Graft/patient survival showed no significant differences among groups. Based on our results we consider CJS the standard method for biliary reconstruction in PSC; however, in selected cases where CJS is difficult to accomplish because of previous surgery or for retransplantation, CDS may present an alternative technique.     

Influence of food quality and quantity on children's teeth]

Sugar and tooth decays are bound closely. The mechanisms of destruction of the tooth from the glycolyse are known. The role played by the food in the development of the caries is unique. Foods sweetened of all ways, rich in sucrose are responsible of the intervening of the carious lesions. The transformation of the fermentable sugars in lactic with the absence of hygiene and the action conjugated of the bacteria leads to tooth decays in temporary and permanent denture that evolve very quickly in the absence of treatment. Reasons for which the authors put in evidence in this survey, the influence of the food sweetened on the teeth at the children while showing the cases of caries and its complications due to the excessive consumption of fermentable hydrates of carbon.     

胰胆管合流异常动物模型的建立

目的建立胰胆管合流异常的动物模型。方法选用健康杂种猫10只。术前禁食12 h,3.5%戊巴比妥钠麻醉后,取上腹正中切口约6 cm切开各层至腹腔。于胆总管入十二指肠处旁边,切开胰腺背膜,解剖胰管;靠近十二指肠处分别纵向切开胰管、胆管长约4~6 mm的切口。6-0线间断吻合切口,造成类似人类的胰胆管合流的共同通道。术后20天胆道造影。结果术后动物精神、食欲良好,无萎靡、烦燥等表现,造影显示胰胆管合流共同通道延长。结论本动物模型最接近于人类的胰胆管合流异常生理,优于其他动物模型。
