Bile duct injuries often occur because of surgeon spatial disorientation. The psychological concept of cognitive map misplacement is a useful explanation of how this disorientation and injury occurs. Surgeons may find that using a "bile duct time out" is a helpful way to orient. Based on the mnemonic B-SAFE, they can use 5 subhepatic landmarks (B, bile duct; S, sulcus of Rouviere; A, hepatic artery; F, umbilical fissure; E, enteric/duodenum) to correctly place their cognitive map.
胆管损伤常因外科医生的空间定向障碍而发生。认知地图错位这一心理学概念有助于解释这种定向障碍及损伤是如何发生的。外科医生可能会发现采用“胆管暂停”是一种有用的定向方法。基于B - SAFE记忆法，他们可以利用5个肝下标志（B，胆管；S，鲁维埃沟；A，肝动脉；F，脐裂；E，肠道/十二指肠）来正确定位其认知地图。
