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, pancreatic external drainage, anastomotic procedure time, histopathological examination, and postoperative complications. Results. Fifty-two patients underwent pancreatoduodenectomy with pancreatojejunostomy using “serous touch” technique (ST group) and 52 classic pancreatojejunostomy (C group). In the ST group one patient (1.9%) was diagnosed as grade B pancreatic fistula, and no patient experienced fistula grade A or C. In the C group 6 patients (11.5%) were diagnosed as fistula grade A, 1 (1.9%) patient as fistula grade B, and 1 (1.9%) patient as fistula grade C. There was a significant statistical difference in incidents of pancreatic fistula (P < 0.05) and no statistical difference in other postoperative complications or mortality in comparison group. Anastomosis time was statistically shorter in the ST group. Conclusions. “Serous touch” technique appeared to be easy, safe, associated with fewer incidences of pancreatic fistulas, and less time consuming in comparison with classical pancreatojejunostomy.
Background: Pancreatoduodenectomy (PD) is a complex procedure with a relatively high risk of complications. There is an increasing trend showing that the success of pancreato-enteral anastomosis depends on surgical skill and the material used. Methods: We present four cases of pancreato-enteral anastomosis resected 37 -114 days after primary surgery and the analysis of the healing process, i.e., morphology of the pancreatic parenchyma, pancreatic duct, and digestive tract mucosa, as well as the pancreatic reaction to the sewing material by microscopic morphometry. Results: Evidence of regeneration in the columnar-lined mucosa of main pancreatic ducts in all cases of pancreato-enterostomy was observed. The inflammatory foreign-body reaction around monofilament stitch was present without an evident infection. There were no microscopic signs of pancreatic duct damage. Total foreign body reaction varied between 138.1 μm and 207.3 μm. Conclusions: This observation supports the beneficial use of thin monofilament threads for pancreato-enteral anastomosis. There was no evidence of harmful action from gastric or intestinal juices on pancreatic remnant or the Wirsung duct.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
