Objective To explore the expression and clinical significance of Twist. E-cadherin and N-cadherin in gallbladder carcinoma. Methods From 2000 to 2008, in Zhejiang Provincial People's Hospital, the expression of Twist, E-cadherin and N-cadherin protein were detected in 79 surgically removed gallbladder carcinoma tissue specimens in paraffin blocks and 20 normal gallbladder tissue specimens by tissue microarray technique and immunohistochemistry. Results Compared with normal gallbladder tissues, the expression of Twist and N-cadherin was up-regulated in gallbladder carcinoma tissues and the positive percentage was 68.3% and 49.4% respectively, while which both were 1/20 in normal gallbladder tissues. The percentage of high E-cadherin expression in gallbladder carcinoma tissues was only 27.8 %, which was significantly lower than that in normal gallbladder tissues (20/20;X2 =29.31, P<0. 05). The expression of Twist was correlated with T classification, lymph node metastasis, distant organ metastasis, hepatoduodenal ligament invasion, lymphatic invasion and UICC stage of gallbladder carcinoma (P<0.05). The expression of E-cadherin was correlated with T classification, distant organ metastasis, hepatoduodenal ligament invasion, differentiation degree and UICC stage of gallbladder carcinoma (P<0.05). The expression of N-cadherin was only correlated with lymphatic invasion of gallbladder carcinoma (P <0.05 ). There was significant negative correlation between Twist and E-cadherin expression (P<0. 01). All the 79 gallbladder carcinoma patients were followed up after the surgery, the mean follow-up time was 30.6±14.3months. The 3-year survival rates of patients with low or high Twist expressions were 66% and 7% respectively,there was significant difference between the two groups(P<0. 01). The 3-year survival rates of patients with low or high E-cadherin expressions were 25 % and 86 % respectively, the difference of two groups was significant(P<0.01). The 3-year survival rates of patients with low or high Ncadherin expressions were 39% and 41% respectively, there was no significant difference between the two groups(P>0.05). The multivariate analysis indicated that the Twist expression was one of independent prognostic factors of gallbladder carcinoma. Conclusion The abnormal expression of Twist and E-cadherin was correlated with the development and progression of gallbladder carcinoma,and Twist expression was one of the independent prognostic factors of gallbladder carcinoma.

Objective To evaluate the clinical significance of re operation for postoperative recurrent gastric carcinoma. Methods From 1986 to 2001, fifty one patients with postoperative local recurrence of gastric carcinoma were admitted into our hospital. The clinical data were analyzed retrospectively. Results Of 51 cases, there were 31 cases with recurrence within the stump stomach and 20 with local and metastatic recurrence. Twenty seven cases were treated by radical resection, 3 cases by palliative residual stomach resection, 15 cases by gastrojejunostomy or gastroenterostomy, 6 cases by simple exploration. Pathological examination of 30 cases revealed perianastomosis recurrence in 10 cases, stump stomach carcinoma in 20 cases. The 1,3,5 year survival rate of 27 cases after radical resection was 88%, 58%, 19% respectively. The survival time of palliative and comprehensive treatment group was 6 to 24 months and mean survival time was 16 months, while all patients undergoing simple exploration and abdominal cavity chemotherapy died after 2 to 7 months. Conclusion Most postoperative recurrent gastric carcinoma are within the residual stomach and hence could be treated by reoperative resection.

Objective To evaluate the result of multiple segmentectomy under selective occlusion of hepatic inflow for complicated intrahepatic cholangiolithiasis. Methods In this study 12 cases of complicated intrahepatic cholangiolithiasis receiving multiple segmentectomy under selective occlusion of hepatic inflow during 2004. 1 - 2010. 10 were reviewed retrospectively. The short-term and long-term outcomes of the patients were analyzed. Results There was no surgical mortality in this group. The segmentectomy performed were Ⅱ + Ⅲ + Ⅴ in 1 case; Ⅱ + Ⅲ + Ⅵ in 2 cases; Ⅱ + Ⅲ + Ⅴ + Ⅵ in 1 case;Ⅱ +Ⅲ+Ⅵ +Ⅶ in4 cases; Ⅱ +Ⅲ +Ⅳ +Ⅵ in 3 cases and Ⅱ + Ⅲ +Ⅳ +Ⅵ +Ⅶ in 1 case. The average intraoperative blood loss was 560 ± 291 ml. Postoperative complications were wound infection in 2 cases, bile leakage in 1 case, abdominal infection in 1 case. There were no liver failure, intrabdominal hemorrhage or hemobilia; stone clearance rate at 10 days after operation was 83% (10/12) and 92%(11/12) at 6 weeks after operation following postoperative choledochoscopic lithotripsy. 92% (11/12) cases were followed-up with the median follow-up period of 31 months. The result was excellent or good in 92% (11/12) cases. Conclusions Multiple segmentectomy was the choice for complicated intrahepatic cholangiolithasis, and the procedure could be safely performed under selective occlusion of the hepatic inflow.

Objective To evaluate right hepatic veins exclusion in the prevention of massive bleeding and air embolism during the resection of huge hepatic cavernous hemangioma near the second hepatic portal. Method This is a retrospective study on the clinical data of 12 hepatic hemangioma patients at the Live Surgery Department of Zhejiang Provincial People's Hospital from 2004. 1 to 2010.3. In all patients the huge hepatic cavernous hemangioma was adjoining the second hepatic portal. Block webbing or vascular clamp were used to exclude the right hepatic veins. Among the 11 patients without hepatic cirrhosis Pringle maneuvre was applied in 5 cases and selective hepatic inflow occlusion in 6 cases. Patients with hepatic cirrhosis used hemi-hepatic blood inflow occlusion. Results During the surgery no rupture of right hepatic vein happened. Nine patients used vascular block webbing and 3 patients used vascular clamp.Six patients without cirrhosis used the complete hepatic inflow occlusion and other patients without cirrhosis used hemi-hepatic blood inflow occlusion. Cirrhotic patients used hemi-hepatic blood inflow occlusion. All the operations were successful. Intraoperative blood loss ranged from 200 - 5800 ml, averaging 680 ml. Three patients needed not blood transfusion. There was no right hepatic vein rupture or air embolism. Conclusion Right hepatic veins exclusion is a useful technique to prevent massive bleeding and air embolism caused by the rupture of right hepatic vein during the resection of huge hepatic cavernous hemangioma.

Objective To study the causes of and management for reoperative surgery in patients of congenital choledochal cyst. Methods The clinical data of 41 patients of congenital choledochal cysts undergoing reoperative surgeries were reviewed. Results There were 32 cases of type Ⅰ , 1 of type Ⅱ ,3 of type Ⅳ, and 5 of type Ⅴ according to Todani classification of congenital choledochal cyst. Thirty patients experienced one previous biliary tract surgery, 8 had a history of 2 surgeries and 3 experienced three times of operations previously. Among the 41 patients, 40 presented bile duct stones, 33 suffered from biliary infections, 7 had hilar hepatic duct strictures, 6 had strictures of previous hepatoenteric anastomosis, 5 had carcinomas arising in cysts. The reoperative surgeries for the 41 patients consisted of excisions of extre-hepatic bile cyst and hepato-jejunal anastomosis by Roux-Y fashion (combining with hepatoduodenal ligament dissection and regional lymphadenectomy for two patients with cholangiocarcinoma) in 32 cases, hepatectomies combined with excisions of choledochal cyst and hepato-jejunal anastomosis in 8 cases, reconstruction of hepatoenteric anastomosis by excision of stenosis in one. All patients were followed up with mean time of 53. 7 ± 32. 1 months, ranging from 3 months to 10 years. Intermittent biliary infection was experienced in 4 cases during follow-up period, and there was no anastomotic stricture and stone recurrence. Conclusion The main causes of reoperation for congenital choledochal cyst patients with a history of previous surgery are complications arising from incorrect surgical procedure and misdiagnosis. Complete excision of extra hepatic bile cyst combined with Roux-en-Y hepatojejunal anastomosis benefits patients who had a failed previous surgery.
