Currently, the pathogenesis of the formation and development of cysts has not been fully studied. This creates the need to analyze existing and fi nd new ways to model pancreatic cysts.The aim: create a new way of modeling the true pancreatic cystMaterials and methods: in an experiment on 7 mongrel dogs, a new method of forming a model of a true cyst of the head of the pancreas was developed, by creating a reservoir from the 12-type intestine with the pancreas, with suturing to the posterior wall of the pyloric part of the stomach.Results: the model of the pancreas cyst proposed by the authors meets the criteria of the true pancreatic cyst and can be used in experimental studies of various methods of cyst treatment.Conclusions: this method is technically simple in execution and allows one-step, in less time to perform the operation.
