The goal of this prospective study is to compare the clinical efficacy of self-gripping mesh in laparoscopic transabdominal preperitoneal versus Lichtenstein hernia repair, in order to improve the outcome of inguinal hernia treatment. The main question it aims to answer is, in which procedure is the self-gripping mesh more effective.

Participants will be divided into the TAPP group and the Lichtenstein group by random number table method, the TAPP group underwent laparoscopic transperitoneal preperitoneal hernia repair, and the Lichtenstein group underwent Lichtenstein hernia repair, both groups used self-gripping meshes.

Researchers will compare the operation time, postoperative time out of bed, postoperative hospital stay, hospital costs and postoperative complications between the two groups to see the clinical efficacy of self-gripping mesh in laparoscopic transabdominal preperitoneal versus Lichtenstein hernia repair.

Inclusion Criteria:

• Male patients aged 18 years and older.
• Patients with a definite diagnosis of unilateral primary inguinal hernia.
• Patients and their families were informed about the study protocol and agreed to participate in the study.

Exclusion Criteria:

• Patients with femoral, recurrent, bilateral, incarcerated and strangulated hernias.

• Patients with contraindications to anaesthesia.
• Patients with contraindications to laparoscopic surgery.
• Failure to follow up patients as scheduled.
• Patients with abdominal infections.
• Those who cannot tolerate general anaesthesia surgery due to serious coagulation disorders, cardiopulmonary disorders, etc.

Patients aged 18 years and older were selected.

Data sharing with other researchers is not planned at this time due to patient privacy concerns.
