The Evaluation of Electrophysiological Methods of Research in Diagnosis and Prediction of Early Intra-abdominal Complications after Colon Surgery

Objective: To assess the effectiveness of electrophysiological methods of research in diagnosis and prediction of early intra-abdominal complications after colon surgery. Background: The main reason of unsatisfactory results of early intra-abdominal complications treatment after colon surgery is delay in diagnosis of these complications and late repeated surgery. Methods: Electrophysiological method used in study includes complex installation of sensor system that registers simultaneously a number of physiological parameters. Results: With a favorable course in the early postoperative period there was a gradual decrease in the sensitivity threshold of the colonic wall according to current strength from 19 ± 4.2 to 9 ± 3.6 mA on the third day after the surgical intervention. If there were intra-abdominal complications in the early postoperative period, the threshold indices varied from 14 ± 2.9 to 24 ± 3.7 mA, and subsequently it happened that they ceased to be detected. This gives us the opportunity to start active methods of detoxification in the treatment group on 18-22 hours earlier than in the control group of patients. In addition, the periods of repeated lavage of the abdominal cavity decreased by (20.0 ± 0.3) hours in comparison with the control group. Mortality in the control group is 28.1%, in the treatment group-19%. Conclusions: Comparing the results of treatment of the main and control groups, it should be noted that the early intra-abdominal complications are diagnosed much earlier in the treatment group of patients, primarily due to the results of electrophysiological research methods.
