Comparison of Laparoscopic Totally Extraperitoneal (TEP) and Lichtenstein Technique

Not Applicable

Completed

• Conditions: Hernia, Inguinal
• Interventions: Procedure: inguinal hernia repair

• Registration Number: NCT05504122
• Lead Sponsor: Kocaeli Derince Education and Research Hospital

Brief Summary

Open tension-free mesh repair (Lichtenstein) and laparoscopic totally extraperitoneal (TEP) repair are the most commonly preferred techniques for inguinal hernia surgery. There's still a debate going on about which of these two techniques (open versus laparoscopic) is effective. This prospective randomized study aimed at comparing the early and long-term results of these two techniques (TEP vs. Lichtenstein).

Detailed Description

Various studies comparing the laparoscopic totally extraperitoneal (TEP) and Lichtenstein techniques have been reported. These studies have shown that TEP repair is associated with less postoperative pain and faster recovery. However, there are different views on the long-term (recurrence, chronic pain, etc.) results of the two techniques. This study was designed to compare the short- and long-term outcomes of open tension-free mesh repair technique(Lichtenstein) and laparoscopic repair technique(TEP).
