['Inguinodynia, defined as pain lasting >3\xa0months after inguinal hernia repair, remains the major complication of hernia operation. We sought to determine the effect of direct perineural infiltration on acute pain and inguinodynia after open inguinal hernia repair.', 'Patients who presented with an inguinal hernia at a university teaching hospital were evaluated prospectively and randomized to either (1) percutaneous ilioinguinal nerve block or (2) percutaneous ilioinguinal nerve block with additional perineural infiltration of the ilioinguinal, iliohypogastric, genitofemoral nerves. All patients in each group received a total of 12\xa0mL of 0.5% bupivacaine. Self-reported faces of pain level (1-10), minutes to discharge from the recovery room, narcotic quantity consumed (oxycodone 5 mg/paracetamol 325 mg), days on narcotics, and incidence of inguinodynia at 3\xa0months were all recorded.', 'Ninety-two patients were randomized in the study. Patients who received perineural bupivacaine infiltration of nerves had less recovery room pain (1.3 vs 3.9, P\xa0<\xa0.001) and shorter recovery discharge times (89 vs 105\xa0min, P\xa0=\xa0.047) and consumed fewer narcotics (9.7 vs 15.1 doses, P\xa0=\xa0.010). The incidence of inguinodynia at 3\xa0months was less in the treatment group (8.2% vs 27.9%, P\xa0=\xa0.013).'] Does perineural bupivacaine injection reduce inguinodynia after inguinal hernia repair?
