BACKGROUND: Mesh based tension free Lichtenstein repair is the most common type of repair performed for inguinal hernia. This study is aimed at analysing and determining the frequency of post–operative complications following Lichtenstein tension free mesh repair of inguinal hernia. METHODS: This is a descriptive study which was performed prospectively in the Department of General Surgery of Sree Balaji Medical College and Hospital, Chennai during the period of June 2018 to December 2018. A total of 50 patients with inguinal hernia were included in the study. All the patients underwent Lichtenstein’s Hernioplasty. Following surgery post–operative complications and recurrence rates were analysed. RESULTS: Average post–operative hospital stay was 4.2±1.04 days. Immediate post–operative complications observed were seroma (3 cases,6%), wound infection (2 cases,4%) and scrotal hematoma (2 cases,4%). Long term complications observed were foreign body sensation in 3 cases (6%) and chronic persistent pain in 2 cases (4%) at the end of 6 months follow up. No recurrence was observed at the end of 6 months. CONCLUSION: Lichtenstein tension free mesh repair has low rate of post–operative complications and recurrence which makes it an effective and reliable procedure in the management of inguinal hernias.
