内镜模拟训练在上消化道内镜培训中的作用研究

目的 探讨内镜模拟训练在上消化道内镜教学中的作用.方法 2005年1月-2007年3月41名无内镜操作经验的进修医师、研究生、住院医师,随机分为两组.非内镜模拟训练组于内镜中心观摩学习1个月后开始操作内镜,内镜模拟训练组于观摩学习的同时接受10 h的内镜模拟训练.由专人对所有受训者最初20例内镜操作进行评价、记录,包括插入食管是否成功、胃内观察是否成功、通过幽门是否成功、进入降段是否成功、总的操作时间.结果 插入食管成功率、进入降段成功率两组间差异无统计学意义;胃内观察成功率(P<0.001)、通过幽门成功率(P<0.001)、总操作时间(P=0.032),内镜模拟训练组均优于非内镜模拟训练组,两组间差异有统计学意义.结论 内镜模拟训练在上消化道内镜教学中有重要作用,有助于受训者迅速掌握内镜操作方法,缩短教学时间,减少患者痛苦.

Upper gastrointestinal endoscopy training With a computer-based simulator: a randomized controlled trial

Objective To explore the role of computer-based simulators in upper gastrointestinal endoscopy training.Methods Forty-one graduate students,residents and GI fellows for further cducation with no experience in endoscopy were randomly assigned to two groups and underwent one-month training with or without a 10-hour computer-based simulator.Each trainee performed upper endoscopy in 20 patients.Comparison was made between the two groups in terms of these performance parameters:esophageal intubation,retroflexion,pyloric intubation,intubation of the descending part of the duodenum and procedure time.Resuits There Was no significant difference in esophageal intubation(P=0.699)and intubation of the second part of the duodenum(P=0.141)between two groups.While the differences were significant in retroflexion (P<0.001),pyloric intubation(P<0.001)and procedure time(P=0.032),i.e.,the simulator group was much better in performance than the other group.Conclusion The computer-bascd simulator is effective in providing trainees with the skills needed for upper gastrointestinal endoscopy,shortening the teaching hours and lessening patients'pain.
