Correlation analysis between post-pancreatoduodenectomy pancreatic fistula and pancreatic histology.

چکیده
OBJECTIVE To evaluate the relationship between the occurrence of pancreatic fistula after pancreatojejunal anastomosis in patients undergoing pancreaticoduodenectomy for periampullary malignancy and the histological fibrosis and inflammation found in pancreatic tissue and the caliber of the main pancreatic duct. METHODS We conducted a retrospective study with patients that were treated with surgical resection. The rate of pancreatic fistulae was recorded. Histology classification was performed according to fibrosis and pancreatic inflammation. RESULTS We identified 77 patients, mean age was 57.6 years; 62.4% were male. As for the type of operation performed, 66.3% were gastroduodenopancreatectomies and 33.7% pancreatoduodenectomies with pylorus preservation. Regarding the number of fistulas diagnosed, it was found that 23.4% patients displayed this postoperative complication and in 66.7% the cause was cancer of the papilla. As for intraoperative macroscopic findings, we identified the classification of pancreatic texture, seen as normal in 85.8%, and the caliber of the main pancreatic duct, finding an average of 4.9 mm. There was a significant relationship between the hardened pancreatic stump and the absence of fistula. In patients with normal or soft tissue, the rate of fistula was 25.4%. Regarding ductal diameter, we identified a higher number of pancreatic anastomotic dehiscences in the absence of ductal dilation (p <0.05). We noticed that patients with an average ductal diameter of 5.4 mm (76.7%) did not show this complication. CONCLUSION The presence of fibrosis and ductal dilation usually coexist and is related to a lower percentage of pancreatic fistulae.

متن کاملPrediction of pancreatic fistula after pancreatoduodenectomy by preoperative dynamic CT and fecal elastase-1 levels
OBJECTIVE To validate preoperative dynamic CT and fecal elastase-1 level in predicting the development of pancreatic fistulae after pancreatoduodenectomy. MATERIALS AND METHODS For 146 consecutive patients, CT attenuation values of the nontumorous pancreatic parenchyma were retrospectively measured on precontrast, arterial and equilibrium phase images for calculation of enhancement ratios. CT...

The aim of this study was to evaluate the place of pancreaticogastrostomy (PG) in reducing pancreatic fistula after pancreatoduodenectomy. From January 1988 to June 1991, 32 consecutive patients (mean age, 57 years) were operated on, 25 for malignant disease (78%). The pancreatic remnant was normal in 17 patients (53%) and sclerotic in the others. There was one operative death (3.1%) unrelated ...
متن کاملTwo-Staged Pancreatoduodenectomy Including Interventional Pancreatic Fistulo-Jejunostomy in a High-Risk Patient
Context It has been reported that two-staged pancreatoduodenectomy including the first operation without pancreatoenteric anastomosis followed by later pancreatojejunostomy in the second operation is a safe method for high-risk patients. But this procedure requires twice laparotomy. Here we report an improved method to avoid the second operation using interventional technique. Case report A Sev...

Background. The aim of the study was to compare two invagination techniques for pancreatojejunostomy after pancreatoduodenectomy. Methods. For effective prevention of the development of pancreatic leakage, we modified invagination technique that we term the "serous touch." We analysed the diameter of the main pancreatic duct, the texture of the remnant pancreas, the method of the reconstruction...
