Long-term follow-up evaluation of chronic pain after endoscopic total extraperitoneal repair of primary and recurrent inguinal hernia

Background Long-term data on chronic pain after endoscopic total extraperitoneal (TEP) hernia repair are hardly available. Methods Between January 1997 and December 1998, 416 patients with consecutive primary and recurrent inguinal hernia underwent endoscopic TEP hernia repair. Long-term follow-up evaluation was carried out from June 2007 to June 2008. The primary outcome measure was persistent pain and discomfort interfering with daily activity. Results The overall response rate was 66% (273 of 416 patients). Of the 416 patients, 85 (20%) had died of causes unrelated to hernia repair and 58 (14%) were lost to followup. A total of 177 patients were physically examined in the outpatient clinic. Because 96 patients were not able to visit the outpatient' clinic, they completed the survey by telephone. The median follow-up period was 10 years (range, 9-11 years). After TEP repair, 16 patients (6%) reported chronic groin pain, and 10 patients (4%) still experience pain at this writing after the 10-year follow-up period. One of the patients has experienced persistent pain and discomfort interfering with daily activity. Patients with preoperative pain have reported significantly more chronic pain (P = 0.03). Conclusions Chronic groin pain after TEP repair of primary and recurrent inguinal hernia seems to have a low incidence after a 10-year follow-up period.
