Hernias are common in children and account for most of the surgical operations performed by the Paediatric surgeons. They often present late in resource-poor countries for a variety of reasons. In these settings, surgical outreaches reduce the burden of hernias. We aim to determine the effectiveness of a tertiary hospital-based surgical outreach for hernia repair in children in a low-resource-setting. We did a prospective study conducted during a surgical outreach carried out over seven days at a tertiary center in Southeast Nigeria. Recruited subjects were physically examined to establish a diagnosis and screened for fitness before surgeries were performed. Data were collected using a structured proforma to information from the patient's case-notes. Data analysis was done using the statistical package for social sciences (SPSS) version 25. There were 77 children with 80 hernia surgeries, 71 (92.2%) males, and 6 (7.8%) females (ratio of 12:1) were involved. The majority (66.2%) were aged 2-12years and were mainly rural dwellers. Right groin hernias were present in 54.5% and 40.3% had left groin hernias. Herniotomy was the main procedure offered (93.5%). The complication rate was 9.1%. Senior registrars in surgery (Senior trainee surgeons) participated in most of the operations. The mean duration of surgery was 34.9 + 17.6 minutes. Surgical outreach in tertiary hospital for hernias in children in resource-poor settings offers the opportunity for mass repairs with good outcomes. It provides a hands-on opportunity for trainee surgeons to improve their mastery of hernia surgery.
