Duodenal Diaphragm in adults is very uncommon, caused by congenital and acquired changes. It is reported that acquired duodenal diaphragm is related to the long-term use of nonsteroidal anti-inflammatory drugs. We report an adult presentation of duodenal diaphragm in a 77-year-old woman, suffered from acute cholangitis and choledocholithiasis. She was performed endoscopic retrograde cholangiopancreatography (ERCP) procedure to remove the stone in common bile duct (CBD). After the stenosis ring dilated by endoscopic balloon dilatation, ERCP procedure was applied, and the CBD stone was removed successfully.
Duodenal diaphragm is difficult to diagnose in clinic. Although the patient in this case had relatively mild symptoms of incomplete upper hemi-abdominal obstruction, these symptoms could be obscured by the emergency acute upper abdominal pain with fever as clinical manifestations of acute cholangitis.
成人十二指肠隔膜非常少见，由先天和后天的变化引起。据报道，后天性十二指肠隔膜与长期使用非甾体抗炎药有关。我们报告了一例 77 岁女性因急性胆管炎和胆总管结石而出现的十二指肠隔膜，她接受了内镜逆行胰胆管造影术（ERCP）以取出胆总管（CBD）中的结石。在狭窄环经内镜球囊扩张后，进行了 ERCP 操作，并成功取出了 CBD 结石。
临床上十二指肠隔膜较难诊断。尽管本例患者的不完全上腹部半梗阻症状相对较轻，但这些症状可能会被急性胆管炎的发热等临床表现所掩盖。
