Conventional radiographic and manometric criteria failed to distinguish 9 irritable bowel syndrome patients with the symptom of rectal dissatisfaction from 6 without it. Manometric values (including sphincter length, resting and squeeze pressures, and the rectoanal inhibitory reflex, as well as rectal compliance and maximum tolerable volume), radiographic indices (anorectal angle and level of pelvic floor at rest and on straining), and tests of anal and rectal sensitivity were all statistically indistinguishable. Conceivably, the symptom results from incomplete rectal emptying; it may also be an early warning of abnormal perineal descent. Only 4 of the 15 patients with irritable bowel syndrome in this study were able to expel a 50-ml balloon from the rectum in the left lateral position.
传统的放射学和测压标准无法区分9名有直肠不适症状的肠易激综合征患者和6名没有该症状的患者。测压值（包括括约肌长度、静息压和收缩压、直肠肛门抑制反射，以及直肠顺应性和最大耐受容量）、放射学指标（静息和用力时的肛管直肠角及盆底水平）以及肛门和直肠敏感性测试在统计学上均无显著差异。可以想象，该症状是由直肠排空不完全引起的；它也可能是会阴下降异常的早期预警。在本研究的15名肠易激综合征患者中，只有4人能够在左侧卧位时从直肠排出一个50毫升的气囊。
