The authors invrstigated whenther samll dose of ursodeoxycholic acif treatment influences biliary concentration, nucleation time and gallbladder empting. 3 patients with cholesferd gallstones receired 400 mg ursodeoxychilic acid per prior to cholecystectomy. Treatment with small dose of ursodeoxycholic acid decreased the gallbladder chlesterol saturation index and prolonged the nucleation time ,bur had no effect on gallbladder empyting. We bilieve that snall dose of ursodeoxyxholic acis mat prevent the gallstone formation by decreasing xholecterol saturation index and lengthening the nucleation time.
ObjectiveTo explore the cause, clinical diagnosis and treatment, and prevention strategies of iatrogenic bile duct injury (IBDI). MethodsBy means of literature retrieval, the clinical diagnosis and treatment measures of patients with IBDI were summarized. ResultsThe related risk factors of IBDI include man-made factors, the local anatomy variation factors, and pathological factors. According to the damage diagnosis time and local pathological state, the repair operations such as bile duct suture repair, biliary tract end to end anastomosis, bile duct jejunum Roux-en-Y anastomosis, bile duct jejunum Roux-en-Y anastomosis, and jejunal artificial valve forming, or liver resection, and liver transplantation were performed. Moreover, it was also available that biliary stent or papillary balloon dilation through ERCP for the bile duct distal stricture. ConclusionsIt is important that prevention of IBDI. Operation should pay attention to upper abdominal operation prior to the implementation of the correct understanding of IBDI. In case of IBDI, the reasonable repair operation mode should be choose according to the damage types and time, and it can significantly improve the treatment effect and quality of life of patients.
