Exploring endoscopic therapy for the treatment of Crohn's disease-related fistula and abscess.
Fistula and abscess represent penetrating disease phenotypes of Crohn's disease (CD) and can develop in patients with or without prior history of CD-related surgery. While CD fistula and abscess have been traditionally treated with medical and surgical therapy, the role of endoscopic therapy in this particular phenotype of CD is expanding recently, thanks to advanced endoscopic techniques and a better understanding of pathogenesis and natural history of the disease and principle of treatment. The success of endoscopic treatment for inflammatory bowel disease depends on comprehension and appreciation of principles, then techniques, followed by instrument and device. Attempts should be made to temporarily or permanently close the feeding side (or the primary) orifice at the gut, by various forms of clipping. Endoscopic fistulotomy is feasible, particularly for perianal fistula and surgery-associated distal bowel fistula. Perianal abscess can be treated with endoscopic incision and drainage and even seton placement. Endoscopic treatment for fistula and abscess as well as for stricture has become an important part of the multidisciplinary approach to complex CD.
