ABSTRACT
Objective To evaluate the clinical values of serum CA19-9 measurements in diseases Of biliary system.Methods Serum concentration of the CA19-9 antigen was determined in 621 patients with biliary diseases.Their serum bilirubin levels,operative managements,pathological factors and survivals were also analyzed.Results The highest effective percentage(93.9%)was observed at the CUt-off value of 37U/ml of serum CA19-9 level.Compared with benign disease group,it had a significant difference of the positive rate in malignant disease group of biliary system.A significant higher sensitivity rate and lower specificity rate were observed in patients with jaundice than those without jaundice.Conclusions The measurement of serum CA19-9 level has a important value for the diagnosis,operative management and prognosis of biliary system diseases.though a confident discrimination between benign and malignant jaundice could not be made on the basis of its elevation.
ABSTRACT
Objective To discuss the cause and preventive measure of positive stump in gastric cancer.Method The clinical data of 426 patients with residual cancer after resection of gastric cancer were retrospectively analyzed.Result In these cases 37(8.7%,37/426) were found to have residual cancers at the margin of resection.Conclusion The incidence of residual cancer at the cut edge is closely related to gross type,size of cancer,tumor stage and degree of differentiation.
ABSTRACT
Objective To investigate a modified technique of pancreaticojejunostomy in pancreaticoduodenectomy ( PD ).Methods The clinical data of 72 patients of PD using the modified technique of duct-to-mucosa pancreaticojejunostomy for treatment of benign or malignant tumor of pancreas or duodenum was retrospectively analyzed.Results There were no operative deaths; 2 of the 72 patients (2.78%) had postoperative pancreatic fistula. 63 patients were followed up. Of the 63 cases, the digestion and absorption functions of gastrointestine were normal in 60 patients and they were well nourished,but 3 patients suffered from chronic steatorrhea and malnutrition.Conclusions The modified duct-to-mucosa pancreaticojejunostomy is a simple and safe technique. With this technique, the rate of pancreatic fistula or leakage is relatively low and the function of the remnant pancreatic is well preserved.
ABSTRACT
ObjectiveTo evaluate the effect of modified Sugiura procedure in the treatment of portal hypertension.MethodWe analyzed the results of modified Sugiura procedure performed in 72 patients suffering from portal hypertension secondary to postohepatitic liver cirrhosis from January 1991 to January 2000.Results There was no operative mortality. Seventy one out of 72 (99%) patients were followed-up with a mean follow-up time of 4 years and 1 month. Hepatic coma and rebleeding rate was respectively 1% and 3%, respectively. ConclusionOur results showed that the effect of modified Sugiura procedure in the treatment of portal hypertension is satisfactory with a low complication rate, and low bleeding recurrence.
