Lichtenstein technique, inserting a mesh over the inguinal cord in the neurological plane, is considered the standard of inguinal hernia repair, but it has 4% recurrence and 12% chronic postoperative pain. Rives technique inserts the mesh in the preperitoneal space behind the neurological plane and the muscular plane, thus better fulfilling the principle of hydrostatics.
These techniques have not been compared randomly for assessment of chronic pain, postoperative complications and recurrences

RECRUITINGEvaluate postoperative complications of pain
The patients are clinically reviewed in the office within 7 days of discharge (pain is evaluated at rest and with movement (standing up, sitting down, and walking), using a VAS (visual analogue scale). Using a ruler, the score is determined by measuring the distance (mm) on the 10-cm line between the "no pain" anchor and the patient's mark, providing a range of scores from 0-100. A higher score indicates greater pain intensity. Based on the distribution of pain VAS scores in post- surgical patients, the following cut points on the pain VAS have been recommended: no pain (0-4 mm), mild pain(5-44 mm), moderate pain (45-74 mm), and severe pain (75-100 mm)
Time frame: 7 days
Evaluate the chronic pain
The patients are reviewed clinically by the service's surgeons again after a year. If pain is found, this is evaluated as being with movement, spontaneous, episodic, or constant in nature, and measured with a VAS.

Time frame: 1 year
Evaluate the recurrences
The patients are reviewed clinically by the service's surgeons again after a year. The inguinal region is examined. A mass, reducible or otherwise, is regarded as a recurrence.
Time frame: 1 year
