Tension-Free Repair of Inguinal Hernia with “Undissociate Spermatic Cord”- Case Series

Background: In recent years, with the deepening of the anatomical cognition of the inguinal region and the renewal of the hernia repair concept, inguinal hernia repair has become increasingly mature surgical approach. However, no matter how the hernia repair modes change, the treatment and repair of the hernia ring has always been the focus, so that the treatment of the hernia sac has been neglected. Materials and Methods: From March 2014 to May 2019, there were 132 patients underwent inguinal hernia repair with “Undissociate Spermatic cord” theory (Undissected Spermatic cord and hernia sac, hernia ring and sac exclusion) in the First Affiliated Hospital of Harbin Medical University and the First Hospital of Harbin. Results: All the operations were completed smoothly. The patients included 126 males and 6 females. There were 74 cases underwent open surgery and 58 cases underwent laparoscopic surgery (TAPP and TEP). In the open group, the mean operation time was 33.4min, and the mean blood loss was 7.1ml. The mean hospitalization time was 4.6d. In the laparoscopic group, the mean operation time was 74.4min, and the mean blood loss was 7.5ml. The mean hospitalization time was 4.7d. There were no complications occurred in our groups. All the patients were followed up for 18~63 months (mean of 41.5 months) without recurrence. Conclusion: Following the “Undissociate Spermatic cord” theory, the inguinal hernia repair could be convenient operation, low complication rate and recurrence rate. The function of spermatic cord was also retained. “Undissociate Spermatic cord” theory is a safe and feasible novel idea for inguinal hernia repair.
