Laparoscopic total extraperitoneal repair versus anterior preperitoneal repair for inguinal hernia

Laparoscopic inguinal hernia repair is still not the gold standard for repair although mesh implantation is unequivocally accepted as an integral part of any groin hernia repair. The aim of the study was to compare the results of anterior preperitoneal (APP) mesh repair with totally extra peritoneal (TEP) repair for inguinal hernias. The prospective study was conducted on 241 patients with 247 hernias (from January 2000 to June 2004). Anterior preperitoneal repair was done in 121 patients and 120 patients were subjected to TEP repair. Repair in both groups was done by using Prolene mesh of size 6×4 in. or 6×6 in. intraoperative and postoperative parameters and complications were recorded and the patients were followed up to 1 year post-surgery. For both unilateral and bilateral inguinal hernias, mean operative time was significantly more in patients of TEP repair as compared to APP repair (P <0.001) and significantly more patients had peritoneal tears in the TEP group (P <0.001). Patients undergoing TEP repair, however, had significantly less postoperative pain (P<0.05) and postoperative hospital stay (P <0.05) and return to work was significantly earlier is this group (P <0.01 and P<0.001). There was no difference in the recurrence rate between the two groups. Patients with inguinal hernias undergoing laparoscopic repair recover more rapidly, and have less incidence of postoperative pain. But it takes significantly more time to perform than APP repair and also the incidence of peritoneal tear is higher. © Springer-Verlag 2006.
