Abstract

Objective. To determine a peculiarities of morphological changes in pancreatic gland after resectional operations, using the high-energy electric surgical instruments (HEESI) and standard surgical procedure.

Маterials and methods. In conditions of experiment a pancreatic resection was performed in white laboratory rats, using a standard surgical procedure and a high-energy electro-surgical instruments (HEESI) in a welding regime (DA2), bipolar and monopolar regimes. Histological investigation of pancreatic gland was done immediately postoperatively and in 3, 7 and 21 days, using a light-optical microscope Leica DМ500.

Results. In early terms after application of a standard surgical procedure a more severe inflammation have had occur and more rapidly the newly created connective tissue volume enhanced, than after application of electro-surgical methods. After all kinds of electro-resection performed in a newly created tissue the ducts have been formatted, what was not observed after application of a standard procedure. After bipolar welding the surface resected have had lesser hematomas, than after application of surgical scissors. After resection, performed, using monopolar welding, a less dense coagulation layer have been created, than after resection, performed with application of a bipolar welding, in 21 days in the resection zone a significantly more volume of connective tissue was created and more significant signs of inflammation persisted, than after application of a bipolar method.

Conclusion. While applying of all kinds of electro-resection the operative intervention duration shortens, the hemorrhage occurrence risk reduces, hermetic joints on the surface resected are created, and the restoration processes do not complicate.
