The relatively high incidence of coexistent hepatobiliary disease increases the difficulty of the surgical management of choledochal cyst. Here we analyze the diagnosis and treatment of congenital bile duct cyst in 122 Chinese adults. Methods The clinical data of 122 patients with congenital choledochal cysts admitted from 1981 to 2006 were analyzed. Results Clinical symptoms in most cases were nonspecific, resulting in delayed diagnosis. Sixty-one patients （50%） had coexistent pancreatobiliary disease. Among the 122 patients, 119 patients underwent ultrasonic examination; ERCP/MRCP was performed in 63 cases and CT in 102 cases. Abnormal pancreatobiliary duct junction was found in 48 patients. Sixteen patients had malignant lesions in the bile duct, arising in 11 of them from incomplete choledochal cyst that underwent various operations including cystenterostomy or cystojejunostomy There was significant difference between the patients who underwent incomplete cyst resection and complete cyst resection in malignancy rate of bile duct （Chi square test, P= 0.000; odds ratio, 7.800; 95 % confidence interval, 2.450 to 24.836）. Conclusions ERCP, CT and MRCP had proved their great values in the classification of the disease. Cyst excision with Roux-en-Y hepaticojejunostomy is recommended as the treatment of choice for patients with type Ⅰ or type Ⅳ cysts. For type Ⅴ cyst （Caroli＇s disease） with recurrent cholangitis, liver transplantation should be considered.展开更多

This is not easily controlled under the laparoscope, especially during right or left hemihepatectomy, except for resection of the peripheral liver or left lateral segment when porta hepatis dissection is not indicated. Although both inflow and outflow control seems to be ideal in laparoscopic left hepatectomy, there have not been many reports of this. In addition to the high technical demands and the time required, any injury of the main hepatic veins or vena cava during the procedure will cause catastrophic bleeding and air embolism. Recently, we succeeded in achieving inflow and outflow occlusion during laparoscopic left hemihepatectomy in four cases, with satisfactory results.展开更多

Here, we use the technique of dissection of the secondary branches of the splenic pedicle to handle the hilum in the portal hypertension patients who are subjected to splenectomy. Methods We retrospectively compared and analyzed the complications, postoperative hospital stay, operative time, and occurrence of hemorrhage in 121 patients with portal hypertension undergoing splenectomy and devascularization of the gastric cardia from January 1999 to December 2007. The selected cases consisted of 51 patients undergoing conventional splenectomy and 70 patients undergoing dissection of secondary branches of the splenic pedicle. In addition, we analyzed the relationship between size of the spleen and occurrence of complications. Results The incidence of pancreatic fistula and splenic fever （0/70 and 9/70） was lower in patients undergoing dissection of secondary branches of the splenic pedicle as compared with that of the conventional group （5/51 and 18/51 respectively）. In addition, there was no significant difference in operative time and volume of blood loss between two groups. The spleen thickness of those patients who had pancreatic fistula and splenic fever was significantly greater than those without complications. Conclusions These results indicate that dissection of secondary branches of the splenic pedicle in portal hypertension patients undergoing splenectomy can decrease the incidence of splenic fever and pancreatic fistula, and shorten the postoperative hospital stay, especially in the patients with a large spleen. So dissection of secondary branches of the splenic pedicle is a valuable technique for splenectomy.展开更多
