离体猪胃模型应用于内镜模拟手术培训的初步探讨

Preliminary study on the training of endoscopic simulated operation in pig stomach model

目的对离体猪胃模型应用于内镜模拟手术培训进行初步探讨。方法对消化科专科医师进行为期6个月的培训,共操作胃ESD 6例及POEM3例,此培训在北京平谷医院动物实验基地进行。进行基础理论知识学习、记录ESD总体操作时间、创面范围、操作部位、操作速度(创面面积/时间)、POEM总体操作时间、隧道长度,并应用李克特量表调查问卷检测学员培训前后的变化。数据应用SPSS25.0统计软件进行分析。结果在胃窦及胃体部位进行ESD操作时间无明显差异,且操作时间与创面大小比较差异不具有统计学意义。POEM成功1例。随着培训次数的增加,学员的操作速度逐渐提高。通过李克特量表调查问卷,发现在对适应症及禁忌症的把握、操作器械的熟悉情况、操作过程的熟悉情况、操作并发症的处理、操作的自信心程度方面均有所提高。结论离体猪胃模型应用于内镜黏膜下剥离术的模拟培训是可行的。

Objective To explore the application of isolated pig stomach model in endoscopic surgery training.IVlethod Six cases of gastric ESD and three cases of POEM were trained for 6 months in the animal laboratory of Pinggu District Hospital.The basic theoretical knowledge was learned.The operation time of ESD,wound scope,wound areas,operation site and operation speed(wound area/time)of E^SD,the operation time of POEM and tunnel length were recorded.The changes of trainees before and after training were detected by Likert scale questionnaire.Data were analyzed by SPSS25.0 statistical software.Result There was no significant difference in ESD operation time between gastric antrum and body of stomach,and there was no significant difference between operation time and wound size.With the increase of training times,the operation speed of trainees was gradually increased.One case of POEM was performed successfiilly.Through the questionnaire of Likert scale,it was found that the master)r of indications and contraindications,the familiarity of operating instruments,the familiarity of operating process,the treatment of complications and the degree of confidence in operation were improved.Conclusion The training of endoscopic submucosal dissection in pig stomach model was feasible.
