Fulminant acute colitis following a self-administered hydrofluoric acid enema.

A 33-yr-old white male presented with bloody diarrhea, leukocytosis, and left lower quadrant direct and rebound tenderness after a self-administered concentrated hydrofluoric acid enema while intoxicated from intranasal cocaine administration. Intraoperative flexible sigmoidoscopy and a gastrografin enema revealed severe mucosal ulceration and edema in the rectum and sigmoid colon. Laparotomy revealed an ulcerated, necrotic, and purulent sigmoid colon and intraperitoneal pus. The patient underwent a limited sigmoid resection and a Hartman procedure. Five months later, the patient presented with a rectal stricture which was resected. This case demonstrates that a hydrofluoric acid enema can cause fulminant acute colitis and chronic colonic strictures.
