LASER IRRADIATION AND ELECTROCOAGULATION EFFECTS ON PANCREATIC PARENCHYMA

Objective. To assess the pancreatic tissue morphological changes in patients with chronic pancreatitis when electrocoagulation and laser resection methods are used.

Materials and methods. Two groups 20 patients in each were formed. Pancreatectomy was performed in Group 1 using electrocoagulation. Resection using laser radiation was performed in Group 2. The pancreas tissue fibrosis severity and the extent of the laser and electrocoagulation damaging effects were determined basing on the light microscopy morphometric data evaluation.

Results. The morphological study showed a significant (p<0.05) decrease in the depth of the thermal damage zone in patients operated on with a laser— 410 [287; 569] pm compared with the mono- and bipolar coagulation — 705 [456; 919]

Conclusion. The laser effects identified can help prevent development of severe postoperative complications (postoperative pancreatitis, bleeding, pancreatojejunostomy leakage) after the pancreatic resection.
