Morphological and functional and ultrastructural features of changes in cell tissues pancreatic pseudocysts using the methods laser vaporization

Abstract

The results of the features of the preoperative (initial) state of the cells of the walls of the pancreatic pseudocysts before the onset of laser radiation and the state of biopsy specimens after laser vaporization were evaluated. This work is based on the results of examination and surgical treatment of 28 patients with pancreatic pseudocysts using, who were divided into two clinical groups. The main group was represented by 12 (42 %) patients who were operated on with the use of percutaneous drainage of the cyst cavity using laser vaporization. The comparison group consisted of 16 (57 %) patients operated on by traditional methods and without the use of laser vaporization. The main surgical techniques of intraoperative use of percutaneous puncture laser vaporization of the pseudocyst wall with external and internal drainage are presented. Based on the results of the morphological analysis of the dynamics and intensity of acute reactive inflammation, it was found that when using the laser vaporization method, the postoperative period and the healing process are faster and more efficient than when using standard open methods of surgical treatment of pancreatic pseudocysts. Laser vaporization is a more effective method of minimally invasive surgical treatment, which immediately allows you to quickly form a thin, dense scab, not only effectively stops bleeding and has a protective function, but also minimizes the intensity of acute reactive inflammation in adjacent tissues. When using laser vaporization, the zones of necrosis and necrobiosis are significantly reduced.
