A man in his early 70s was transferred to our hospital due to rapid decline in renal function and inflammation throughout the colon, indicating severe ischaemic enteritis. On the day following the start of intensive care, a stool specimen tested positive for verotoxin, and haemolytic uraemic syndrome (HUS) was diagnosed. On the same day, his vital signs deteriorated suddenly, and emergency surgery was performed due to the possibility of intestinal necrosis and perforation. Severe inflammation extending to the serosal surface of the whole colon was observed, but there was no obvious intestinal necrosis or perforation. Advanced mucosal necrosis of the entire colon suggested sepsis due to bacterial translocation, and subtotal colectomy was performed to remove the infection source. Postoperative management was successful. This case demonstrates the importance of considering HUS in patients with severe renal dysfunction and bloody stools, as well as the significance of colectomy in such patients.
