We analyzed the pancreatic fistula rate according to the clinical characteristics, the pathologic and laboratory findings, and the anastomotic methods.RESULTS: The incidence of developing pancreatic fistulas in patients older than 60 years of age was 21.7% (25/115), while the incidence was 8.8% (5/57) for younger patients; the difference was significant (P = 0.03). Patients with a dilated pancreatic duct had a lower rate of post-operative pancreatic fistulas than patients with a non-dilated duct (P = 0.001). Other factors, including clinical features, anastomotic methods, and pathologic diagnosis, did not show any statistical difference. CONCLUSION: Our study demonstrated that pancreatic fistulas are related to age and a dilated pancreatic duct. The surgeon must take these risk factors into consideration when performing a pancre-aticoduodenectomy.展开更多

Pancreatic fistula occurred in 14 patients （11%） among the interrupted suture cases and in 10 （6%） among the continuous suture cases （P = 0.102）. Major pancreatic leakage developed in three interrupted suture patients （2%） and zero continuous suture patients （P = 0.026）. In multivariate analysis, soft pancreatic consistency （odds ratio, 5.5; 95% confidence interval 2.3-13.1） and common bile duct cancer （odds ratio, 3.7; 95%CI 1.6-8.5） were＇predictive of pancreatic leakage.CONCLUSION： Pancreatic texture and pathology are the most important factors in determining the fate of pancreaticojejunal anastomosis and our continuous suture method was performed with significantly decreased occurrence of major pancreatic fistula. In conclusion, the continuous suture method is more feasible and safer in performing duct-to-mucosa pancreaticojejunostomy.展开更多

Methods： Two hundred patients undergoing PD at our hospital between December 1996 and September 2002 were reviewed retrospectively. Standard PD was performed on 176 cases, standard PD with extended lymphadenectomy on 24 patients, whereas pylorus-preserving PD was not used. An end-toside combined with mucosa-to-mucosa pancreaticojejunostomy was performed on the patients with a hard pancreas and a dilated pancreatic duct, and a traditional end-to-end invagination pancreaticojejunostomy on the patients with a soft pancreas and a non-dilated duct. The risk factors with the potential to affect the incidence of complications were analyzed with SAS 8.12 software. Logistic regression was then used to determine the effect of multiple factors on early complications. Results： The overall rate of the major com- plications was 21% （42/200）, with the failure of pancreaticojejunal anastomosis being the most frequently encountered. Age （odds ratio [OR] 2.162）, diabetes mellitus （OR 4.086）, total serum bilirubin level （OR 7.556）, end-to-end pancreaticojejunostomy （OR 2.616）, T tube through the choledochojejunostomy （OR 0.100）, and blood transfusion over 1000 mL （OR 2.410） were the significant risk factors for the morbidity. Conclusion： The results from published series concerning morbidity after pancreaticoduodenectomy are not comparable because of lack of homogeneity between them. The knowledge of the complications rate in each particular department turns out essentially to provide the patient with tailored information about risks before surgery. Additionally, management of postoperative complications is essential for improving the results of this operation.展开更多
