About this study
Official title: Prospective Randomized Study of Comparison Mesh Displacement in Bilateral Laparoscopic İnguinal Hernia Repair With No Fixation: eTEP Versus TEP
Inguinal hernia surgery is one of the most frequently performed procedures among general surgery cases. As with many open surgical methods, this repair is also performed laparoscopically. Among these closed methods, the one method is laparoscopic extended total extraperitoneal repair (eTEP). The benefits of laparoscope include less postoperative pain and complications, faster recovery, reduced chronic pain, and recurrence rate.
One of the recent debates regarding the laparoscopic technique is mesh fixation. Fixation of the mesh to the cooper ligament can prevent mesh migration and consequently reduce the recurrence rate. However, it has been reported that this fixation may increase postoperative pain. Several studies have reported that recurrence may be due to inadequate mesh fixation technique. In contrast, other prospective randomized studies have found relapse unrelated to mesh fixation.
There are studies in the literature on mesh fixation related to the total extraperitoneal repair (TEP) technique. These studies are generally planned for unilateral hernias. It is a controversial issue among surgeons that the possibility of mesh migration is higher in bilateral hernias since there is a larger dissection area. This discussion is the starting point of this study. There were no studies in the literature regarding mesh fixation in bilateral inguinal hernias. The aim of this study is to compare bilateral inguinal hernia patients with and without mesh fixation in the eTEP technique in terms of both mesh migration and clinical features.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
TEP groupProcedure or surgery
Inguinal hernia surgery will be performed with the TEP method and the 15x12x10 cm polyprolene patch used in this surgery will be marked with small metallic clips from the lateral, superomedial and inferomedial sides.
eTEP groupProcedure or surgery
Inguinal hernia surgery will be performed with the eTEP method and the 15x12x10 cm polyprolene patch used in this surgery will be marked with small metallic clips from the lateral, superomedial and inferomedial sides.
| Study group | Role | What they receive |
|---|---|---|
| TEP Group | Active comparator | In 20 patients; Bilateral inguinal hernia surgery will be performed with the TEP method and the 15x12x10 cm polyprolene patch used in this surgery will be marked with small metallic clips from the lateral, superomedial and inferomedial sides. During the surgery, the mesh will not be fixed. Patients whose pain scores (VAS score) are measured on the first postoperative day and who are suitable for discharge will be discharged after a pelvis x-ray is taken. One month after the surgery and 6 months later, patients will be called to the outpatient clinic and examined, their pain scores will be measured (VAS score) and pelvic radiographs will be taken. The movement of the clips marked on the patch will be compared with previous radiographs in cm. Receives: Procedure: TEP group |

What is being measured
The primary outcome is the main question the study is designed to answer.
Status of Mesh Displacement
Patients who are suitable for discharge will be discharged after a pelvis x-ray is taken. One month after the surgery and 6 months later, patients will be called to the outpatient clinic and examined and pelvic radiographs will be taken. The movement of the clips marked on the patch will be compared with previous radiographs in cm.
Measured: postoperative 24 hours, 1 and 6 months
Secondary outcomes (4)
Rate of Postoperative pain
It will be measured using the Visual Analog Score (VAS). The patient will be asked to choose between the number 1 with the least pain and the number 10 with the most pain. The lowest score on this scale is 1, and the highest score is 10.
Measured: postoperative 24 hours
Rate of Hernia recurrence
hernia recurrence after six months of follow-up. It will be checked by physical examination. Imaging methods will be used in suspicious cases.
Measured: postoperative 6th month
Rate of Postoperative complications
such as wound infection, bleeding
Measured: postoperative 24 hours and 1st month
Rate of Chronic pain
It will be measured using the Visual Analog Score (VAS). The patient will be asked to choose between the number 1 with the least pain and the number 10 with the most pain. The lowest score on this scale is 1, and the highest score is 10.
Measured: postoperative 1st and 6th month

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.

Among these closed methods, the one method is laparoscopic extended total extraperitoneal repair (eTEP). The benefits of laparoscope include less postoperative pain and complications, faster recovery, reduced chronic pain, and recurrence rate.
