Clinical Data Analysis for Treatment of Adult Inguinal Hernia by TAPP or TEP

Background: Transabdominal preperitoneal (TAPP) repair and totally extraperitoneal (TEP) repair are the primary surgical methods for the treatment of adult inguinal hernia, but it remains necessary to consider which one to choose in clinical practice. Our study seeks to compare the efficacy of laparoscopic TAPP and laparoscopic TEP in the treatment of adult inguinal hernia and to explore which surgical method is a better choice. Methods: A retrospective analysis of 686 adult patients with inguinal hernia admitted to our hospital from the period January 2016 to December 2020 was conducted. According to different surgical methods, they were divided into two groups: a TAPP group (n = 361) and a TEP group (n = 325). These two groups of patients were statistically analyzed, and the operation time, postoperative pain, postoperative hospital stay length, postoperative complications, and recurrence rate were compared between them. Results: There were no significant differences in postoperative hospital stay, complications, and the recurrence rate between the two groups (p > 0.05). The duration of operation in the TEP group was significantly shorter than that in the TAPP group, and the difference was statistically significant (p < 0.001); in terms of postoperative pain, the TEP group fared better than the TAPP group, and the difference was statistically significant (p < 0.001). Conclusion: TAPP and TEP are safe and effective surgical methods in the treatment of adult inguinal hernia. However, compared with TAPP, TEP can significantly shorten the operative time, reduce intraoperative trauma, and limit postoperative pain in the treatment of adult inguinal hernia. Furthermore, it does not increase the rate of complications or recurrence, so it is worth popularizing.
