Diabetes mellitus and inadequate glycaemic control are important, independent risk factors for postoperative recurrence of perianal abscess, with a clear dose-response relationship between HbA1c and recurrence risk. The internally validated prediction model, which combines HbA1c with other readily available clinical variables, shows promise as a tool for early identification of high-risk patients and may support more personalized perioperative optimization and follow-up. External validation and impact studies are required before routine implementation in diverse clinical settings.
