Atypical midgut malrotation presenting as chronic bowel obstruction in the eighth decade.

An elderly patient was referred urgently to our rapid access suspected colorectal cancer clinic with symptoms suspicious for malignancy. Despite exhaustive investigations, no cause for his symptomatology could be identified. However, his condition deteriorated and we elected to undertake exploratory surgery, at which time a congenital midgut malrotation, causing chronic small bowel obstruction, was identified. The malrotation was surgical corrected and the patient has made a full recovery.
