The role of intraperitoneal hypertension in the development of postoperative eventration in cancer patients

Abstract

Despite the development of modern surgery, postoperative surgery continues to be one of the most dangerous complications, especially in patients with malignant tumors of the abdominal cavity, where there are phenomena of secondary immunodeficiency, cachexia, anemia, etc. occur. One of the many factors that directly lead to postoperative surgery is the sharp increase in intraperitoneal pressure, which is quite common in cancer patients in the early postoperative period. The study of the frequency of development of the postoperative eventration, depending on the level of intraperitoneal and abdominal perfusion pressures in patients with cancer of the abdominal organs, will allow determining the role of the latter in the development of this postoperative complication. The purpose of the research is to study the frequency of postoperative event development in patients with malignant tumors of the abdominal cavity, depending on the level of intraperitoneal and abdominal perfusion pressures.Material and methods. We examined 122 operated patients with malignant tumors of the abdominal cavity, which underwent a median laparotomy. Depending on the average level of HRT patients are divided into three groups. The first group consisted of 57 (46.7%) individuals with a mean IVT level below 12 mmHg. The second group consisted of 40 (32.8%) with an average HFT level of 12 - 17 mmHg. The third group consisted of 25 (20.5%), with an average TBI of over 18 mmHg. Depending on the average level of APT, the first group consisted of 48 (39.3%) individuals with an average level of APT above 90 mmHg. The second group was 43 (35.3%) with an average level of APT - 89 - 56 mmHg. The third group consisted of 31 (25.4%), in whom the average level of APT was less than 55 mmHg.Results. The results of the study indicate a significant difference in the incidence of postoperative events in groups of patients with higher TBI and, respectively, lower APT (study groups 2 and 3). This proves a certain relationship between the levels of HRT, APT and the frequency of postoperative event development.Conclusion. The frequency of development of postoperative events is directly dependent on the levels of intraperitoneal and abdominal perfusion pressures in the early postoperative period, which makes it possible to consider the latter as one of the factors of development of this complication and markers of its prognosis.
