Towards a standardised classification system for giant inguinal hernia

Effective pre-operative risk stratification and classification are crucial for optimizing surgical outcomes in giant inguinal hernias (GIHs). However, there is no universally accepted classification system for GIH, which complicates risk assessment, surgical planning, and research comparability. This narrative review aims to evaluate existing classification systems for GIH and identify their limitations. There is a proposal for a new classification system that might need to be tested widely. Several classification systems were identified. The classification of GIH was based on four broad groupings: Skin redundancy, risk of abdominal compartment syndromes, scrotal volumes, and lower-limb landmarks alone. Most of these classifications failed to incorporate key risk factors such as loss of domain, visceromegaly, and the potential for abdominal compartment syndrome. In addition, most existing classifications did not account for inguinoscrotal hernias above the mid-thigh. Most current classification systems for GIH have significant limitations, particularly in preoperative risk stratification and surgical planning. There is an urgent need for a standardized, comprehensive classification that considers key prognostic factors such as loss of domain and the risk of abdominal compartment syndrome. Future research is necessary to refine the existing classification models and develop a universally accepted system that improves patient outcomes and facilitates research comparison.
