Laparoscopic extraperitoneal inguinal hernia repair versus open mesh repair: long-term follow-up of a randomized controlled trial

Abstract

We have conducted a randomized controlled trial of totally extraperitoneal hernia repair (TEP) versus tension-free open repair (Lichtenstein repair); we have presented the results previously up to 1 year after the operation. The aim of this study was to compare patient outcome in both groups at a median follow-up of 7.3 years after operation. Of 168 patients included in a prospective, randomized controlled trial designed to compare TEP with an open tension-free technique, 154 patients (92%) answered a questionnaire and 147 patients (88%) were followed up at an outpatient clinic after a minimum of 6 years after operation. Overall, 89% of patients in the TEP group and 95% of patients in the open group reported complete long-term recovery (P = .23). Permanent impaired inguinal sensibility was more common in the open group (P = .004), whereas the proportion of patients with reported testicular pain was higher in the TEP group (P = .003). Three recurrences were found in the TEP group, and 4 recurrences were found in the open group (P = .99). Four patients in the TEP group underwent operations for complications related to the hernia repair (small bowel obstruction, umbilical hernia, testicular pain, and neuralgia). Overall, both groups showed good long-term results with low rates of recurrences. However, the TEP group was associated with a higher proportion of patients with long-term testicular pain, whereas impaired inguinal sensibility was more common in the open group.
