胃肠镜检查十二指肠大乳头时透明帽的辅助观察效果

 目的 探索胃肠镜检查十二指肠大乳头时透明帽的辅助观察效果。方法 选取72例拟行胃十二指肠镜检查的患者随机分成两组。实验组使用透明帽辅助进行检查,对照组为单纯胃十二指肠镜检查,比较两种方法对十二指肠大乳头的完整观察和其他检查效果。结果 实验组中,33/36(91.7%)的患者完成了十二指肠大乳头的完整观察,明显优于对照组的19/36(52.8%)(P<0.001)。从食管插管到观察大乳头的时间,实验组少于对照组,差异有统计学意义(P<0.05)。与对照组比,实验组有更高的十二指肠疾病检出率(16.7% vs 8.3%),但差异无统计学意义。结论 透明帽辅助胃肠镜检查十二指肠大乳头更便于观察,成功率更高,且可以缩短观察时间。

Clinical study of cap-aided gastroduodenoscopy for visualization of the major duodenal papilla

Objective To study the efficacy of cap-aided gastroduodenoscopy for the examination of the major duodenal papilla.Methods Seventy-two patients who underwent gastroduodenoscopy were randomly assigned to receive cap-aided gastroduodenoscopy (experimental group) and conventional gastroduodenoscopy (control group).The efficacy of visualization of the major duodenal papilla and other diagnostic indexes were compared between the two groups.Results In the experimental group, the percentage of patients who completed the whole examination of the major duodenal papilla was 91.7%, which was higher than 52.8% in the control group (P<0.001). In the experimental group,intubation from the esophagus to the end of major duodenal papilla took a significantly shorter time than in the control group (P<0.05). The detection rate of duodenal lesions was higher in the experimental group than that in the control group(16.7% vs 8.3%). However, no significant difference was found.Conclusions Compared with conventional gastroduodenoscopy, cap-aided gastroduodenoscopy can achieve a higher rate of whole examination of the major duodenal papilla and shorten the observation time of the esophagus to the end of the major duodenal papilla.
