Abstract:Objective To explore the feasibility of three-dimensional(3D) reconstruction and visualization technique in medical postgraduate education and standardized residency training of precision liver surgery. Methods From 2015 to 2018, the 3D reconstruction visualization technique was applied to the clinical work of precision liver surgery and standardized training in the affiliated Huaian No.1 People′s Hospital and teaching of 15 postgraduates(experimental group); from 2012 to 2015, the teaching method guided by traditional two-dimensional images was used to train 15 postgraduates (control group); Training and assessment contents were as follows:(1)hepatic segment and the anatomy of the liver;(2)clinical manifestations of common liver diseases and the imaging differential diagnosis;(3)hepatectomy with Glisson pedicle transection method;(4) complications after hepatectomy,and causes and treatment measures;(5) the concept of precision liver surgery and enhanced recovery after surgery.The results of graduation examination with the same standard were compared between two groups,and the experiences in the process of standardized training were investigated by anonymous questionnaire． Results The average test scores were (84.70±4.40) in experimental and (79.50±6.20) in control group(P<0.05).The questionnaire survey showed that the scores of interest in learning, work enthusiasm, ability to deal with patients, doctor-patient communication ability and teamwork ability of postgraduates in the experimental group were higher than those in the control group (all P<0.05).The postgraduates in experimental group believed that the standardized training learning was more vivid,interesting and easy to understand compared to the traditional method and helped them to realize self-value and to work better in the future. Conclusion The visualization technique of 3D reconstruction can be effectively used in the standardized training and teaching of postgraduates in precision liver surgery and is help to the growth of graduate students.
