摘要
Intestinal duplications especially rectal duplications are uncommon congenital developmental anomalies. Rectal duplication complicated with adenocarcinoma is even scarcer. Here we present a rare case of a 38 year-old Chinese male who was diagnosed with rectal duplication with canceration. After reviewing lots of related literatures from domestic and abroad, we'd like to discuss the pathogenesis, diagnostic criteria, the clinical characteristics, the treatment modalities, the prognosis of this disease and provide treatments for similar cases. Although 12 cases of rectal duplication complicated with adenocarcinoma has been described, we failed to discover any reports about the precise curative effect of postoperative radio-chemotherapy on the disease. The patient received abdominal perineal resection and six times chemotherapy without evidence of tumor recurrence in 18 months' follow-up.
