目的:了解吞环试验在诊断功能性便秘和明确便秘类型中的作用。方法:选择2013年3月-2014年10月在本院就诊的25例便秘患者为研究对象,将其设为观察组,25例自由接受检查的人员设为对照组。50例研究对象均服用1颗装含有25粒自制小铁环的胶囊,密切观察不同阶段的腹部X线平片,直至自制小铁环粒数小于4粒后停止观察。结果:观察组中有14例为重度传输功能迟缓,比例为56%;11例为传输正常,比例为44%。对照组中有19例为重度传输功能迟缓,比例为76%;6例为传输正常,比例为24%,组间比较,差异具有统计学意义(P<0.05)。结论:吞环试验对功能性便秘的诊断具有一定的临床价值。
Objective: To understand the role of swallow ring test in the diagnosis of functional constipation and clear constipation types. Methods: Twenty-five patients with constipation in our hospital from March 2013 to October 2014 were selected as the observation group and 25 as the control group. All 50 subjects took a capsule containing 25 small homemade iron rings and observed the abdominal plain radiographs at different stages closely until the number of homemade small ferrous beads was less than 4 and the observation was stopped. Results: In the observation group, 14 cases were delayed in severe transmission, with a ratio of 56%. Eleven cases were normal transmission with a ratio of 44%. In the control group, 19 cases were delayed for severe transmission, with a ratio of 76%; 6 cases were normal transmission with a ratio of 24%. There was significant difference between the two groups (P <0.05). Conclusion: The swallow ring test has some clinical value for the diagnosis of functional constipation.
