Percutaneous endoscopic external ring (PEER) hernioplasty

Abstract

This pilot study was conducted to determine if percutaneous endoscopic external ring (PEER) hernioplasty would be a viable alternative to the conventional and laparoscopic methods of tension-free repair. The procedure consists of (1) a 2.0-2.5-cm incision over the external inguinal ring to reach the emerging spermatic cord structures, and ligation and excision of the hernia sac and (2) insertion of an endoscope-attached retractor through the external ring, into the inguinal canal for visualization, dissection of posterior inguinal wall, and placement of mesh to complete tension-free repair. PEER hernioplasty was used to treat 48 patients with 60 primary hernias (bilateral in 12 patients) between January 1993 and December 1994. Median follow-up was 12 months and ranged from 5 to 22 months. All patients were discharged within 24 h after surgery except for one. All patients resumed their normal activity within 2-3 weeks. Only three complications were encountered (two scrotal hematomas and one inguinal seroma). To date, there has been recurrence of two hernias in one patient. We conclude that PEER hernioplasty is an effective method of repair of primary hernias that is less invasive than the conventional approach and both less invasive and more cost-effective than laparoscopic approaches.
