A 40-YEAR-OLD MAN PRESENTED TO THE EMERGENCY DEPARTMENT WITH vomiting and diarrhea. He had no known medical history and had not received antimicrobial therapy recently. His heart rate was 132 beats per minute, and other vital signs were normal. Examination was notable for confusion and for diffuse tenderness to palpation of the abdomen with tympany. Laboratory testing showed a white-cell count of 29,000 per cubic millimeter (reference range, 4000 to 10,800) and a positive nucleic acid amplification test for Clostridioides difficile. Computed tomography of the abdomen revealed pancolitis with distention of the sigmoid and descending colon (Panel A; arrowheads indicate the areas of distention, and two-dimensional measurements of colon width are shown). Despite 2 days of treatment with oral and rectal vancomycin and intravenous metronidazole, shock developed in the patient on hospital day 3. An urgently obtained radiograph of the abdomen showed worsening distention of the transverse colon near the hepatic flexure to 120 mm (abnormal width, >60 mm).
