体外诱导磁控胶囊内镜进入小肠的临床研究

Clinical study on extracorporal induction of magnetic capsule endoscopy into small intestine

摘要:

目的??探讨体外诱导磁控胶囊内镜（MCE）进入小肠的方法及应用价值。方法?将40例接受MCE检查的患者随机分为两组：对照组在胃部检查结束后停止控制胶囊运动，使其随患者消化道蠕动进入小肠；研究组胃部检查结束后患者取右侧卧位，检查医生将胶囊移至幽门口，并调控磁球位置使其靠近患者右下腹，借助磁力诱导胶囊进入小肠。对比分析两组MCE胃部检查时间、胃部滞留时间、小肠通过时间及全小肠检查完成率的差异。结果?对照组平均胃部检查时间为（32.50±11.71）min，与研究组（31.75±9.12）min比较差异无统计学意义（P >0.05）。胃部检查结束后，对照组的胃部滞留时间为（40.60±21.43）min，全小肠检查完成率为40%；研究组胃部滞留时间为（13.55±9.62）min，全小肠检查完成率为75%，两组比较差异有统计学意义（P <0.05）。对照组小肠通过时间为（329.25±90.00）min，与研究组（342.00±89.80）min比较差异无统计学意义（P >0.05）。结论?体外调控磁球位置结合患者体位改变可显著缩短MCE胃部滞留时间，提高全小肠检查完成率。

Abstract:

Objective?To explore and evaluate an extracorporal method for inducing magnetic capsule endoscopy into small intestine.?Methods?40 patients receiving magnetic capsule endoscopy were randomly divided in two groups: the control group: doctors stopped manipulating capsule after the examination of stomach, and the capsule entered small intestine by the natural gastrointestinal motility; and the study group: after the examination of stomach, the patient lay on the right side, doctors moved the capsule to the pylorus, and then moved magnetic ball to induce capsule into small intestine. Gastric inspection time, gastric residence time, small intestine transit time and the completion rate were compared between the two groups.?Results?The average time for checking stomach was (32.50 ± 11.71) min in control group and (31.75 ± 9.12) min in study group respectively, and the difference was not significant (P > 0.05). After the observation of stomach, the gastric residence time in the control group was (40.60 ± 21.43) min, and the completion rate was 40%, while the average gastric residence time in the study group was (13.55 ± 9.62) min, and the completion rate was 75%. The difference between the two groups was statistically significant (P < 0.05). Small intestine transit time was (329.25 ± 90.00) min in the control group and (342.00 ± 89.80) min in the study group, and the difference was not significant (P > 0.05).?Conclusion?By doctors moving magnetic ball and the patient lying on the right side after the observation of stomach, gastric residence time could be reduced and the completion rate could be elevated obviously.
