Recent years, lots of treatment teqnique have development. We aimed that comparising the normal and small size meshes in the inguinal hernia patients.

Data Collection Method: The research will be a multicentric, prospective and randomized clinical study to be conducted between 01.11.2018 and 28.02.2019 by the general surgery clinics of Mogadishu-Somalia Recep Tayyip Erdogan Training and Research Hospital and Health Sciences University Konya Training and Research Hospital.

Male patients with inguinal hernia repair will be included in the study. Patients will be randomized into two groups. While the normal size of 15 x 7 cm (105 cm2) mesh was used in the first group, In the second group, a small size 11 x 5 cm (55 cm2) mesh will be used.

Dismissal criteria are; Female patients, relapse hernias, bilateral inguinal hernia, laparoscopic hernia repair, diabetic patients using insulin, patients with COPD, peripheral vascular disease, emergency inguinal hernia repair, patients with high ASA score, patients with serious cardiological problems, heavy smokers, transfusions during the perioperative period.

Patients will be given clear and understandable information about the study. Patients who agree to participate in the study will receive a consent form explaining that they have participated in the study voluntarily.

Randomization is done by the secretary with a computer program. A note stating which group the patient is in is placed in a closed envelope and an envelope is opened at the preoperative surgery table.

The method of operation will be open inguinal hernia repair (Lichtenstein hernia repair). The patient will be repaired with mesh suitable for the randomization group. Operations will be performed under the supervision of an experienced surgeon or experienced surgeon.

Surgical Method: Patients will receive open inguinal hernia repair, known as Lichtenstein hernia repair. According to the Gilbert classification, the hernia type is recorded in the patient file.

Evaluation of patient characteristics and pain: the researcher will not know in which group the patients are. Demographic features, duration of surgery, hernia type, early postoperative complications, return to work will be recorded in the study forms. If there is a suspicion of recurrence in the physical examination, a recurrence assessment will be performed by ultrasonography and magnetic resonance examination if necessary. Recurrences will be detected at 1, 6, 12, and 24 and recorded on the study form.

Values will be recorded in the form by using the Sheffield Scale in the assessment of chronic pain.
