Abstract
A 26-year-old man developed acute abdominal pain one week after stomach fluoroscopy, and visited our hospital. An abdominal CT showed free air and barium cavity from the descending colon to the sigmoid colon. Emergency surgery was performed under a preoperative diagnosis of colonic perforation. We recognized a perforation area in the contralateral mesentery of the descending colon, and hard feces covered with barium from the perforation area to the cecum colon. We removed the bowel segment with the perforation, and constructed a colostomy in the descending colon. Histopathologically， abscess formation was noted around the perforation, with neutrophil and lymphocytic infiltration. We made a final diagnosis of stercoral colonic perforation of the descending colon. A stercoral colonic perforation by the barium in a young man with no underlying disease is rare.
