When portal venous pressure exceeds 12 mmHg, portosystemic collaterals develop. Common sites include the oesophago-gastric junction, bare area of the liver, anterior abdominal wall, and the anorectal junction. Variceal haemorrhage from the oesophago-gastric junction is voluminous, overt, and usually easily accessible, however occult bleeding from ectopic varices presents the ultimate challenge to those managing gastrointestinal haemorrhage. In this article we describe two cases of ectopic varices with an outline of the management strategy for such patients.
当门静脉压力超过12 mmHg时，门体侧支循环会形成。常见部位包括食管胃交界处、肝裸区、前腹壁和肛管直肠交界处。食管胃交界处的静脉曲张出血量大、明显，通常易于处理，然而，异位静脉曲张的隐匿性出血给处理胃肠道出血的人员带来了极大挑战。在本文中，我们描述了两例异位静脉曲张病例，并概述了此类患者的管理策略。
