Introduction: Surgical repair of complex ventral hernia repairs are difficult to perform and are associated with peri-operative complications and recurrence. Many surgical techniques have been studied to improve the outcomes of complex ventral hernia repairs and Transversus abdominis muscle release technique is one such procedure. Objectives: To find out the outcome of transversus abdominis muscle release (TAR) procedure done in patients with complex ventral hernia. Materials and method: A prospective study was done among 10 patients with complex ventral hernia presented to General Surgery department of Vinayaka mission’s medical college and hospital, Karaikal for a period of 1 year. All the patients underwent transversus abdominis muscle release with sub-lay mesh by open method. The patients were discharged on 7th postoperative day. All the patients were followed up for a period of 6 months to identify the outcomes of the procedure and any delayed complications after discharge from the hospital. The results of the study are analysed and presented in the form of mean with standard deviation and percentage. Results: Mean age of the patients was 59.4 years ranging from 45 to 76 years. Among the total 10 patients, 6 (60%) were females. Majority (40%) of the patients had incisional hernia. The most common previous surgical procedure was hysterectomy. Average duration of hernia among the participants was 3.4 years. The average size of the defect was 6.3 cm and 2 patients had multiple defects. During the stay in hospital, 2 patients (20%) developed wound related complication such as seroma formation. At the end of 6 months of follow-up there was no recurrence of hernia in the patients
