摘　　要：目的:探讨磁共振(MRI)排粪造影对女性出口梗阻型便秘(OOC)病因的诊断价值。方法:2023年我院收治OOC女性患者60例,均采用MRI排粪造影与X线排粪造影对OOC病因进行诊断。以临床确诊病因为标准,比较MRI排粪造影与X线排粪造影的诊断效果。结果:X线排粪造影对直肠前突、直肠内套叠、会阴下降、盆底痉挛、肠疝的诊断准确率均高于MRI排粪造影,但除肠疝的诊断准确率差异有统计学意义(P<0.05)外,其他均无统计学意义(P>0.05);MRI排粪造影对膀胱脱垂和子宫脱垂的诊断准确率显著高于X线排粪造影(P<0.05)。结论:与X线排粪造影相比,MRI排粪造影诊断女性OOC病因有优势亦有劣势,其对结直肠病变引起的OOC诊断效果不如X线排粪造影,但对因膀胱脱垂和子宫脱垂引起的OOC诊断效果显著。MRI排粪造影对X线排粪造影诊断OOC病因有补充作用。Objective To investigate the diagnostic value of magnetic resonance imaging(MRI)defecography in female outlet obstructive constipation(OOC).Methods MRI defecography and X-ray defecography were used to diagnose the cause of OOC in 60 female patients admitted to our hospital in 2023.The diagnostic effect of MRI defecography and X-ray defecography was compared according to the criteria of clinical diagnosis.Results The diagnostic accuracy of X-ray defecography for rectal protrusion,rectal intussusception,perineal descent,pelvic floor spasm and intestinal hernia was higher than that of MRI defecography,but there was no statistical significance in the diagnostic accuracy except for intestinal hernia(P<0.05).The diagnostic accuracy of MRI defecography for bladder prolapse and uterine prolapse was significantly higher than that of X-ray defecography(P<0.05).Conclusion Compared with X-ray defecography,MRI defecography has both advantages and disadvantages in the diagnosis of female OOC.It is less effective than X-ray defecography in the diagnosis of OOC caused by colorectal lesions,but it is more effective in the diagnosis of OOC caused by bladder prolapse and uterine prolapse.MRI defecography is complementary to X-ray defecography in diagnosing the cause of OOC.
