Hirschsprung disease presenting as sigmoid volvulus: A case report and review of the literature

While sigmoid volvulus is commonly seen in older patients, it is rarely encountered in children and younger adults. Consequently, heightened awareness of this entity is required to avoid a delay in diagnosis. Among the pediatric and adult cases of colonic volvulus previously reported in the English literature, 23 of the affected individuals have also been diagnosed with Hirschsprung disease (HD). This report describes a 12-year-old male with a history of chronic constipation who presented with vomiting and abdominal distension and was found to have sigmoid volvulus with previously unrecognized HD. The case presentation is followed by a review of the literature describing colonic volvulus secondary to HD in children.
