IRCT20190511043548N1 IRCT 2019-06-02 Arak University of Medical Sciences Comparison between results of three different repair methods of unilateral inguinal hernia Comparison between results of ''Lichtenstein'', "Read-Rives" and "MCvay" repair for treatment of unilateral inguinal hernia in patients referring to Arak university of medical science's hospitals 2019-08-23 anticipated 144 Complete https://irct.ir/trial/39457 interventional Randomization: Randomized, Blinding: Not blinded, Placebo: Not used, Assignment: Parallel, Purpose: Treatment, Randomization description: Patients were randomly assigned to 'Lichtenstein'', "Read-Rives" and "MCvay" groups according to table of random numbers. To use random number table, the researcher will first set the table numbers to read (for example, up, down, left, or right), then numbers will be considered for different groups (for example, taking 00- 48 for intervention A (Liechtenstein method), numbers 49-96for intervention B (Read-Rives method), and numbers 97-144 for group C (Mcvay method). Then the researcher will put his hand on one of the numbers and moves in one of the predefined directions and records the numbers and assigns them to different groups. N/A Unilateral inguinal hernia. Intervention 1: Intervention group: Lichtenstein technique (This method is one of the anterior tension free techniques in inguinal hernia repair that mesh is placed between internal and external oblique muscles and in front of transversalis fascia). Intervention 2: Intervention group: Read-Rives technique (This method is one of the tension free techniques in inguinal hernia repair that mesh is placed under transversalis fascia and on the peritoneum). Intervention 3: Intervention group: MC vay technique (This method is one of inguinal hernia repair techniques that inguinal and femoral defects is repaired with together).
