Abstract
Three patients with anisakiasis of the colon were described. All were men aged 40, 59, and 45 years. The presenting symptom was slight epigastric, periumbilical, or lower abdominal pain. Leukocytosis was present in two patients. Upper GI series and endoscopy were unremarkable. Subsequent Gastrografin enema showed a stenotic change of the ascending colon in all the patients. Two patients also had multiple protruded lesions. Colonoscopy revealed a worm in the center of a reddish edematous area. Removal of the worm using a biopsy forceps resulted in a complete relief of the symptom. The significance of the urgent gastrografin study immediately followed by colonoscopy is worthy of note in the diagnosis and treatment of anisakiasis of the colon.
