Primary carcinoma of the duodenum is an uncommon cause of epigastric pain, weight loss, and vomiting. The diagnosis is frequently made at a late stage and the prognosis is poor. These tumours may easily be overlooked if the whole of the duodenum is not examined at barium meal or endoscopy. The clinical, radiological and endoscopic findings in three cases are described and the differential diagnosis is discussed. The possibility of an infrapapillary carcinoma of the duodenum should be considered in all patients with unexplained upper gastrointestinal symptoms or blood loss.
十二指肠原发性癌是引起上腹部疼痛、体重减轻及呕吐的少见病因。诊断常于疾病晚期作出，预后较差。如果在钡餐检查或内镜检查时未对整个十二指肠进行检查，这些肿瘤很容易被漏诊。本文描述了3例患者的临床、放射学及内镜检查结果，并讨论了鉴别诊断。对于所有有无法解释的上消化道症状或失血的患者，均应考虑十二指肠乳头下癌的可能性。
