Objective To evaluate the treatment and clinical outcome of pancreatic pseudocysts.Methods Clinical data of 53 pancreatic pseudocyst patients treated from Jan 2008 to Oct 2014 was retrospectively analyzed.Results 9 cases underwent CT-guided percutaneous catheter drainage,among them 3 cases underwent reoperation.8 cases underwent endoscopic ultrasonography-guided transmural drainage,including transgastric approach in 7,transduodenal approach in 1,Procedures in all these 8 cases were successful and pseudocyst disappeared completely without complication.Surgical procedures were performed in 36 cases,3 by external drainage,1 of the 3 underwent reoperation;11 cases underwent cystgastrostomy,with 2 suffering from postopertative gastrointestinal bleeding;3 cases underwent cystduodenostomy;19 cases underwent Roux-en-Y cystojejunostomy,with 1 suffering from postopertative gastrointestinal bleeding.Follow-up ranged from 4 months to 6 years,there was no cyst recurrence.Conclusion The treatment of pancreatic pseudocysts is diversified and should be individualized.Internal drainage is the mainstay of treatment,preferably through endoscopic ultrasonography-guided transmural drainage,leaving difficult cases to open cystojejunostomy.

Objective:To evaluate the correlation between the prognosis of patients with hilar cholangiocarcinoma and the degree of bile duct dilatation in MRCP .Methods:The clinical data of 89 patients with hilar cholangiocarcinoma undergoing radical operation at Tianjin Nankai Hospital from Jan 2009 to Dec 2013 were analyzed retrospectively.Results:Tumor size ( P=0.024), Bismuth-Corlette classification ( P=0.048) and tumor stage ( P=0.013) were related factors of biliary dilatation. Tumor differentiation ( P=0.002), R 0 resection ( P=0.002) and biliary dilatation ( P<0.001) were independent predictors of disease-free survival (DFS). Conclusion:The imaging evaluation of the degree of biliary dilatation has a certain predictive value for the prognosis of patients with hilar cholangio-carcinoma.
