Multidrug Resistance and Flaring up of Manifestation in Fistulizing Crohn's Disease after Surgery on a Perianal Lesion.

Crohn's disease is a chronic inflammatory disease of the gastrointestinal tract with relapsing and remitting episodes. Abscesses and fistulas are the most common presentations of anorectal Crohn's disease. Antibiotics and surgical incision and drainage have been successful in treating perianal disease. We present here a 48-year-old woman with known case of Crohn's disease who presented with massive swelling in the perianal region with severe throbbing pain and high-grade fever, 38.2°C; the surgeon noted a large perianal abscess near the anal verge with redness, hotness, and tenderness. One and a half months from perianal abscess surgery, culture sensitivity was done due to delayed wound healing and passage of greenish discharge, and it revealed highly resistant bacteria , , and Staphylococci. In conclusion, clinicians should be aware that abscess and fistula have a fair chance to develop in Crohn's disease patients who are using immunomodulating and immunosuppressant therapy. In abscess and fistula cases, surgery should be determined as soon as possible, and close clinical monitoring should be performed. We recommend routine screening for enteric fistula and culture sensitivity of any discharge prior to the initiation of any antibiotic. Appropriate intervention should then be undertaken.
