Adult Hirschsprung disease: salvage to total colectomy - a rare case report

A 17-year-old male with chronic constipation presented with acute obstipation and abdominal distension. Computed tomography showed a dilated colon with rectosigmoid transition. Initial laparotomy and segmental resection confirmed Hirschsprung disease (HD) on histopathology. One month later, he re-presented with abdominal distension. Urgent total colectomy and ileostomy were performed. He recovered after ICU care and was discharged with a functioning ileostomy. This case underscores complications of incomplete resection in adult HD and the need for vigilant follow-up.
