A 39-year-old male presents with bloody diarrhea. Multiple stool examinations fail to reveal any ova or parasites. A barium examination of the patient’s colon reveals a characteristic “string sign.” A colonoscopy reveals the rectum and sigmoid poions of the colon to be unremarkable. A biopsy from the terminal ileum reveals numerous acute and chronic inflammatory cells within the lamina propria. Worsening of the patient’s symptoms results in emergency resection of the distal small intestines. Gross examination of this resected bowel reveals deep, long mucosal fissures extending deep into the muscle wall. Several transmural fistulas are also found. What is the best diagnosis for this patient?
