Surgical therapy of perianal Crohn's disease

The surgical management of perianal Crohn's disease is complex with a wide range of operations being described. The initial emergency treatment is to drain any source of underlying sepsis. A loose seton drainage or a defunctioning stoma can then be used as a ‘bridge’ to definitive treatment allowing both adequate assessment of the condition and preventing further sepsis. The likelihood of success of any surgical repair must be weighed against the risk of faecal incontinence. Improved results of a local surgical repair are seen with optimal surgical and medical management of perianal Crohn's disease.
