May I ask where your abscess is located? Also, was there a fistula present? My daughter had an abdominal abscess 3 months ago. It was at her Termianl Ilium, and had a fistula to it as well. It was treated with a CT guided drained, and a drain line in for about a week. She took Flagyl for several weeks afterward, and seems okay so far. Our GI did suggest Remicade as well, but I'm really not ready to try such a sophisticated drug yet, and have opted for Imuran.
My daughter was diagnosed Feb. 19/07, (13 yrs. old at time of diagnosis), with Crohn's of the Terminal Illium. Has used Prednisone and Pentasa. Started Imuran (02/09), had an abdominal abscess (12/08). 2cm of Stricture.
