Background: It is generally accepted that most inguinal hernias should be operated on electively in order to avoid the high morbidity and mortality associated with incarceration and small bowel obstruction. The present study reassesses the indication for surgery in asymptomatic inguinal hernia patients.
Methods: We analyzed profiles, separately, for elective and emergency inguinal herniorrhaphies and compared the morbidity and mortality rates.
Results: Two hundred randomly selected elective hernia repairs were compared with 67 incarcerated cases. Postoperative complications were more common following emergency (23.9%) than elective repair (10.5%); however, in both groups, minor complications predominated. The mortality rate in the incarcerated group (6%) was clearly linked with a high preoperative American Society of Anesthesiologists (ASA) score. A bowel resection rate of 4.5% was found in the incarcerated cases, which was not correlated with mortality.
Conclusions: Patients with asymptomatic inguinal hernia and unfavorable medical conditions should be recommended an elective repair, preferably under local anesthesia, to avoid the high mortality associated with an emergency operation.
