Objective To explore the cause, diagnosis, and treatment methods of portal vein thrombosis （PVT） after splenectomy. Methods The clinical data of 29 patients who were got splenectomy because of portal hypertension or traumatic splenic rupture from August 2002 to August 2008 in our hospital were analyzed retrospectively. Results Tweenty-seven patients with PVT were treated successfully, whose thrombi were absorbed completely or partially. One case died of peritonitis，septic shock，and multiple organ failure. One case died of hematemesis, hepatic coma，and multiple organ failure. Tweenty-four patients were followed up, the follow-up time was 0.5 to 3 years, the average was 2 years. Two cases died of massive hemorrhage, 1 case died of hepatic encephalopathy，and 1 case died of liver failure. Two cases occurred deep venous thrombosis in one year after treatment, and the remaining patients had no recurrence of venous thrombosis. Conclusions PVT have some connection with the raise of blood platelet and the hemodynamic changes of the portal vein system after splenectomy. Standardization of operation, early diagnosis, early line anticoagulant，and antiplatelet adhesion therapy are effective way to prevent and treat PVT.
【Abstract】ObjectiveTo evaluate the injury of common bile duct in immediate removal of the ligation in cholecystectomy. MethodsEighteen healthy Japanese rabbits were selected and divided into three groups randomly: A group treated with simple cholecystectomy, B group with cholecystectomy plus common bile duct crossligation and C group with cholecystectomy plus hepatic bile duct conjunction “Y”type ligation. The ligation was removed after 5 min in B and C groups. The levels of serum transaminase and bilirubin and pathological changes of bile duct and liver in each group were observed respectively. ResultsThere were no statistic difference in the levels of GPT, GOT, total bilirubin (TB), direct bilirubin (DB) and DB/TB on 12 hours before operation and the 1st and 7th day after operation between A and ligation groups (Pgt;0.05). But there were statistic difference in the those indexes and pathological changes of bile duct and liver between A and ligation groups on the 30th and 90th day after operation (Plt;0.05). ConclusionDuring cholecystectomy, immediate removal of common bile duct ligation doesn’t affect shortterm results, but the long-term results are bile duct stricture and obstruction.
