The effect on the electroactivity of the abdominal muscles of the level of connective tissue dysplasia and the method of combined hernioplasty of the inguinal hernia

Abstract

Introduction. Combined methods of hernioplasty appear to be a promising surgical treatment of inguinal hernias, allowing reducing suture tension due to the contraction and stretching of the abdominal muscles optimized during the operation. This protects the inguinal region from relapse in severe connective tissue dysplasia.The aim of research was to study the influence of the level of connective tissue dysplasia and methods of combined hernioplasty of inguinal hernias on the electroactivity of the abdominal muscles.Methods. The study included 151 patients with inguinal hernias. The electroactivity of the abdominal muscles and the level of severity of connective tissue dysplasia were studied in these patients before and after combined methods of hernioplasty according to Milkovskaya Dmitrova diagnostic scheme; this also includes tension-reducing mechanism.Results. In the preoperative period, the decrease in the parameters of electromyograms compared to the healthy side in the inguinal region was 67.2%, compared to the region over the group of lateral muscles - 55% and compared to the region over the rectus abdominis muscles - 23.6%. The increase in the electrical activity of the rectus muscles against the background of a decrease in the severity of connective tissue dysplasia to the middle and light levels obtained 43.5% and 77.9%, respectively.The average frequency parameters of electromyograms of the abdominal muscles after combined tension-reducing hernioplasty of inguinal hernias seemed to be most significant: in the inguinal regions on the side of the hernia they amounted to 91.95 7.1 vibrations per second, in the region over the group of lateral muscles - 94.61 4.6/s and in the region over the rectus abdominis muscles - 93.7 2.9/s. Moreover, approximately similar rehabilitation of the rectus and lateral abdominal muscles was reported, which allowed balancing oppositely directed tension forces in the abdominal wall.Conclusion. Thus, in patients with inguinal hernias before surgery, the decrease in the electroactivity of the lateral muscle group was more pronounced than the decrease in the electroactivity of the rectus abdominis. The combined tension-reducing hernioplasty of inguinal hernias contributed to the most significant electromyographic rehabilitation of the abdominal muscles.
