Duct-to-mucosa pancreaticojejunostomies with a hard pancreas and dilated pancreatic duct and duct-to-mucosa pancreaticojejunostomies with a soft pancreas and non-dilated duct

Background. We performed duct-to-mucosa pancreaticojejunostomy with resection of jejunal serosa in 55 patients, and here compare the clinical results between duct-to-mucosa pancreaticojejunostomies with a non-dilated pancreatic duct and those with a dilated duct. Patients and methods. In the period 1999 to 2005, 55 patients (27 F, 28 M; mean age 63.4 years) underwent duct-to-mucosa pancreaticojejunostomy with resection of jejunal serosa. A non-dilated pancreatic duct was observe in 29 patients in group A and a dilated pancreatic duct in 26 patients in group B. Clinical characteristics (age, gender, benign or malignant condition, presence of diabetes mellitus, anastomotic time) were analyzed in both groups and postoperative complications were compared between groups. Results. In a comparison of clinical characteristics, all factors were similar between groups. In group A, the postoperative complication occurred in 4 (wound infection in 2, pulmonary embolism in 1, gastric ulcer in 1) of 29 patients (13.8%), and in group B in 1 (pneumothorax) of 26 patients (3.8%). No pancreatic leakage was observed in either group. The difference between group A and group B in the rate of postoperative complication was not statistically significant. Conclusions. There was no statistical difference in the rate of postoperative complications, including pancreatic leakage, between duct-to-mucosa pancreaticojejunostomies with a dilated pancreatic duct and those with a non-dilated duct. We consider that the diameter of the pancreatic duct is irrelevant to results of duct-to-mucosa pancreaticojejunostomy.
