A case of extensive colonic dilation complicated by ileus due to Hirschsprung's disease in adults: An easily missed diagnosis

Hirschsprung's disease is a congenital condition characterized by the absence of ganglion cells in the colon. While approximately 90% of cases are diagnosed before the age of five, the occurrence of Hirschsprung's disease in adults is rare and frequently overlooked. This report presents the case of a 61-year-old male patient who was admitted to the hospital with symptoms indicative of intestinal obstruction caused by dilatation of the entire colon. A comprehensive medical history combined with computed tomography findings suggested Hirschsprung's disease. The patient subsequently underwent a subtotal colorectal resection with ileorectal anastomosis. A postoperative follow-up at five months indicated favorable outcomes.
