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).

Interventions

Patients who will undergo inguinal hernia repair will be divided into two groups(TEP versus Lichtenstein) according to the technique to be applied
