Lichtenstein and Total Extraperitoneal Techniques in Inguinal Hernia Surgery: A Comparison of the Intraoperative and Early Postoperative Complications Between the Two Approaches.

Background and objective The Lichtenstein technique (LSt) and total extraperitoneal technique (TEPt) are the most frequently performed surgical procedures for inguinal hernia (IH). This study aimed to compare LSt and TEPt in terms of intraoperative and postoperative complications as well as recurrence rates. Methods This retrospective study involved patients hospitalized for IH repair. The study included a total of 262 patients (LSt group: n=125; TEPt group: n=137).  Results The follow-up period of the patients ranged between 16 and 30 months (mean: 22.3 months). While intraoperative complications were more commonly reported in the TEPt group, postoperative complications were more common in the LSt group (2.9% vs. 1.6%). Postoperative bleeding/hematoma developed in three (2.4%) patients in the LSt and three (2.2%) in the TEPt group. One of the patients in the LSt group was reoperated due to persistent bleeding. Two patients in the LSt and two in the TEPt group were reoperated for postoperative recurrence (1.6% vs. 2.4%). One patient was reoperated due to chronic persistent pain. Seroma was aspirated in three (2.4%) patients in the LSt and two (1.5%) in the TEPt group. Conclusion This study revealed no significant difference between TEPt and LSt groups regarding intraoperative and postoperative complications. We propose that both TEPt and LSt could be safely performed in cases of primary and complex IH by selecting the appropriate method based on the hernia type and patient and with sufficient surgical experience.
