Alimentary tract duplications are uncommon anomalies that usually present in childhood. They are most common in the ileum but can occur anywhere along the alimentary tract. In this report, we describe an adult with an ileal duplication and review 12 other reported cases of ileal duplication in adults. Abdominal pain, nausea and/or vomiting, weight loss, and hematochezia were the most common symptoms. No patient was correctly diagnosed before operation. Three patients had malignant neoplasm in the resected specimens. Resection of the duplication and adjacent bowel is recommended because of the common blood supply to both, the possibility of malignant degeneration, and the risk of gastrointestinal ulceration and hemorrhage from ectopic gastric mucosa.
消化道重复畸形是一种罕见的异常情况，通常在儿童期出现。它们在回肠最为常见，但可发生于消化道的任何部位。在本报告中，我们描述了一名患有回肠重复畸形的成人，并 reviewed 其他 12 例成人回肠重复畸形的报告病例。腹痛、恶心和/或呕吐、体重减轻和便血是最常见的症状。术前无患者被正确诊断。3 例患者在切除标本中发现恶性肿瘤。由于两者有共同的血供、存在恶性变的可能性以及异位胃黏膜导致胃肠道溃疡和出血的风险，建议切除重复畸形及相邻肠段。
