ABSTRACT
OBJECTIVE: The Lichtenstein mesh technique is recommended as the standard surgical procedure for inguinal hernias. Shouldice is the best non-mesh technique. However, there are reports that the transinguinal preperitoneal technique (TIPP), which uses a preperitoneal mesh, has potential advantages in relation to the Lichtenstein and the Shouldice techniques. PATIENTS AND METHODS: Three hundred patients with inguinal hernias were randomized into three groups of hundred patients each: Group 1 whose inguinal hernia repair was performed using the Lichtenstein technique; Group 2 using the Shouldice technique; and Group 3 using TIPP. The parameters for monitoring were: length of operation, blood loss, length of hospitalization, length of incision, post-operative pain, and the patient's satisfaction level. RESULTS: The visual analog scale (VAS) score after 6, 12, 24 and 48 h, and 14 d was lower in TIPP than the Lichtenstein and Shouldice groups (p < .0001). The satisfaction level was higher in TIPP than in the Lichtenstein and Shouldice groups (p < .0001). CONCLUSIONS: TIPP technique has advantages in comparison with the Lichtenstein and Shouldice techniques. This method takes a shorter time, the skin incision is smaller, the VAS score is lower and the patient satisfaction level is higher. These advantages are in balance with the higher costs of this procedure.
