Most of the complications occur due to a lack of knowledge of the anatomy or misidentification of the cystic duct. Thus, the study of the anatomy is a cornerstone of a successful procedure and the preoperative magnetic resonance cholangiopancreatography (MRCP) is a way to preoperatively determine relevant structures to avoid intraoperative incidents.\n\nThis trial has been designed to assess the effect of preoperative virtual reality training based on MRCP on intraoperative performance and outcome.",[84,85,86,87,88],"Virtual Reality","Gallbladder","Bile Duct Injury","Medical Education","Laparoscopy","2025-04-10",{"date":91,"type":92},"2025-04-15","ACTUAL",{"date":94,"type":92},"2021-11-01",{"date":96,"type":78},"2026-06-30",{"name":5,"class":6},1]
