BackgroundIn contrast to the well-described 10% risk of chronic pain affecting daily activities after adult groin hernia repair, chronic pain after childhood groin hernia repair has never been investigated. Studies of other childhood surgery before the age of 3 months suggest a risk of increased pain responsiveness later in life, but its potential relationship to chronic pain in adult life is unknown.MethodsThis was a nationwide detailed questionnaire study of chronic groin pain in adults having surgery for a groin hernia repair before the age of 5 years (n = 1075).ResultsThe response rate was 63.3%. In the 651 patients available for analysis, pain from the operated groin was reported by 88 (13.5%) patients whereof 13 (2.0%) patients reported frequent and moderate or severe pain. Pain occurred primarily when exercising sports or other leisure activities. Patients operated on before the age of 3 months (n = 122) did not report groin pain more often or with higher intensity than other patients did.ConclusionsGroin pain in adult patients operated on for a groin hernia in childhood is uncommon and usually mild and occurs in relation to physical activity. Operation before the age of 3 months does not increase the risk of chronic pain.
