Cardiac rhythm variability in patients with inguinal hernias in the postoperative period using a grid and autotissue to close the inguinal canal

Introduction. The expediency of using autotissues in inguinal hernias is dictated by the risk of implant-associated complications. The method of assessing heart rate variability objectifies their advantages in light of the body's adaptive capabilities. The purpose of this study is to develop a hernioplasty method for patients with low stress tolerance and high risk of adaptive failure. Materials and methods. An open comparative study enrolled 87 men with inguinal hernia. Patients were randomly divided into two groups: the main group (n=43) underwent non-tension hernioplasty using autologous inguinal canal tissues (Russian Patent No. 2456928), while the control group (n=44) received standard Lichtenstein repair with a mesh implant. Heart rate variability (HRV) was recorded one hour before surgery and on the first postoperative day. Pain intensity was assessed using the Visual Analog Scale (VAS). Results. Preoperatively, no significant HRV differences existed between groups. Postoperatively, a significant difference emerged in HF % values (р=0,019). The median HF % in the main group increased from 25,0 % to 32,0 % (р=0,031), while it decreased in the control group from 23,6 % to 20,0 % (р=0,24). Conclusion. Autologous non-tension hernioplasty (Russian Patent no 2456928) represents a viable alternative to mesh prostheses, particularly for patients with low stress tolerance and high risk of adaptive failure.
