Chronic pain following totally extra-peritoneal inguinal hernia repair: a randomized clinical trial comparing glue and absorbable tackers.

Purpose: Chronic pain following inguinal hernia repair occurs in up to 20% of patients. The underlying mechanism probably involves sensory nerve damage and abnormal healing that might be influenced by the materials chosen for mesh fixation. The main objective of this study was to compare glue and absorbable tackers on the rate of chronic pain after surgery in patients undergoing totally extraperitoneal inguinal hernia repair (TEP).
