Previous research has shown that the repair of a recurrent inguinal hernia is subject to a greater risk of additional recurrence. Further, bilateral inguinal hernia is subject to a greater recurrence risk than unilateral inguinal hernia. These increased risks may be due to certain anatomical difficulties that complicate the surgical approach in these types of patients. Some clinicians have suggested that laparoscopic approaches are better suited to recurrent and bilateral hernias, and in we delineate separate comparisons for primary, bilateral, and recurrent hernia.
This study was conducted from May 1, 2007 to March 30, 2012. Patients with uncomplicated groin hernia were randomized to transabdominal preperitoneal (TAPP) or totally extraperitoneal (TEP) techniques. A total of 160 patients were randomized to group I (TEP) and 154 patients to group II (TAPP). Pain was assessed with Visual Analogue Scale (VAS) preoperatively and postoperatively at 24 h, 1 week, 6 weeks, 3, 6, and 12 months, and yearly thereafter. Quality of life was assessed with Short Form-36 version 2 (SF 36v2) preoperatively and postoperatively at 3 months follow-up.Significant improvement from preoperative to postoperative quality of life was seen in both TEP and TAPP repairs, but there was no difference between TEP and TAPP in postoperative period. Time to return to normal activity also was similar between the two groups.
