三维影像可视化重建技术在肝胆外科肝段解剖教学中的应用研究

目的 探讨三维影像可视化重建技术在肝胆外科肝段解剖教学中的应用价值。方法 选取2020年3月—2021年4月徐州医科大学附属医院肝胆外科规范化培训住院医师62名,简单随机化方法分为传统教学方法组(A组)和三维可视化教学组(B组), 各31人,分别进行对应教学培训,培训结束完成教学有关评价。对比2组规培医师的学习效果、认知评分和教学满意度。结果 B组肿瘤肝段判定(84.31±7.12)分、肝脏“五叶八段”分析(83.09±6.53)分、脉管与肿瘤关系(77.67±6.71)分、手术方案制订(89.71±5.24)分,均高于A组的(72.41±8.55)分、(69.08±8.11)分、(72.03±7.88)分、(71.55±8.49)分(P<0.05)。B组对肝脏解剖的主观理解得分(8.52±1.37)分、学习兴趣(9.11±0.72)分、临床思维培养(7.37±0.89)分、手术过程认知(8.79±0.91)分,均高于A组的(7.07±1.43)分、(7.19±1.12)分、(6.03±1.38)分、(7.36±1.18)分(P<0.01)。B组教学满意度为93.5%,高于A组的74.2%(χ2=4.292,P=0.038)。结论 三维影像可视化重建技术有助于规范化培训住院医师更好地掌握肝脏肝段解剖,增加其主动学习能力,有效提高教学质量,值得在临床实践教学中推广应用。

Application of three-dimensional image visual reconstruction technology in teaching of hepatic segment anatomy in hepatobiliary surgery

Objective To explore the application value of three-dimensional image visual reconstruction technology in the teaching of hepatic segment anatomy in hepatobiliary surgery. Methods Totally 62 residents of the standardized training of hepatobiliary surgery in the Affiliated Hospital of Xuzhou Medical University from March 2020 to April 2021 were selected. The simple randomized method was used to divide them into a traditional teaching method group (Group A) and a three-dimensional visual teaching group (Group B), with 31 people in each group. The corresponding teaching training was carried out respectively. After the training, the teaching evaluation was completed. The learning effect, cognitive score and teaching satisfaction of the two groups were compared. Results In Group B, the scores of tumor liver segment determination (84.31±7.12), liver “five leaves and eight segments” analysis (83.09±6.53), vascular and tumor relationship (77.67±6.71) and operation plan formulation (89.71±5.24) were higher than those in Group A: (72.41±8.55), (69.08±8.11), (72.03±7.88) and (71.55±8.49), respectively (P<0.05). The scores of subjective understanding of liver anatomy (8.52±1.37), learning interest (9.11±0.72), clinical thinking training (7.37±0.89) and operation process cognition (8.79±0.91) in Group B were higher than those in Group A: (7.07±1.43), (7.19±1.12), (6.03±1.38) and (7.36±1.18), respectively (P<0.01). The teaching satisfaction of Group B was 93.5%, higher than 74.2% of Group A (χ2=4.292, P=0.038). Conclusions The three-dimensional image visua reconstruction technology is helpful to standardize the training of residents to better master the anatomy of liver segments, increase their active learning ability, and effectively improve the teaching quality. It is worth popularizing in clinical practice teaching.
