少量钡餐胃肠传输功能检查及其临床意义

Examination of gastrointestinal transmitting function with small amount of barium meal and its clinical significance

目的探讨少量钡餐胃肠传输功能检查的效果、优势及临床意义。方法30例健康人和50例便秘病人一次吞服40g钡糊后行腹部X线检查,直至钡剂完全排出。结果健康人和便秘病人胃、小肠、结肠、直肠、全消化道的通过时间分别是(189±64)min、(330±108)min、(2239±659)min、(136±49)min、(2801±735)min和(212±87)min、(366±94)min、(3665±1322)min、(650±219)min、(5973±2341)min。与健康人相比,便秘病人钡剂在结直肠内存留时间明显长于健康人(P<0.01),而在胃、小肠内存留时间虽然有所延长,但差异无统计学意义(P>0.05)。结论少量钡餐胃肠传输功能检查图像清晰,定位准确,结果可靠,具有传输功能与形态兼顾的优势,能为便秘分型提供准确数据。

Objective To investigate the effect, preponderance and clinical significance of the examination of gastrointestinal transmitting function with small amount of barium meal. Methods Thirty cases of healthy subjects and 50 patients with constipation swallow 40 g barium meal once, then abdominal fluoroscopy or plain films were taken until barium meal being egested totally. Results The transit time of stomach, small intestine, colon, rectum and the whole digestive tract were （189 ± 64） minutes, （330± 108）minutes, （2239 ± 659）minutes, （136 ± 49）minutes, （2801 ± 735）minutes in healthy subjects and （212 ± 87）minutes, （366 ± 94）minutes, （3665 ± 1322）minutes, （650 ± 219）minutes, （5973 ± 2341）minutes in constipation patients respectively. The transit time of colon and rectum in constipation patients was obviously longer than that of healthy subjects （ P〈0.01）. There was no significant difference between healthy subjects and constipation patients in transit time of stomach and intestine （P 〉0.05）. Conclusion The pictures of the examination with small amount barium meal are clear, precis, reliable, and provide exact data for constipation classification.
