The aim of this study was to determine if digital assessment of anal sphincter tone predicts whether a rectal balloon is needed to prevent incontinence during a barium enema examination. During an 8 month , 306 patients scheduled for barium enema examination were evaluated. Immediately before each examination as good, fair, or poor. The barium enema was then performed in a conventional manner. Leakage of even small amounts of barium was scored as rectal incontinence. Ability to retain the barium enema correlated closely with the strength of rectal bone, regardless of patient sex or age. For different sphincter tones the incidence of rectal incontinence was: good, 2%, fair, 30%; and poor, 90%. From these findings it is recommended that, irrespective of patient age and sex, the use of rectal balloon catheters be limited to patients with poor or fair rectal tone.
本研究的目的是确定肛门括约肌张力的数字评估是否能预测在钡剂灌肠检查期间是否需要直肠球囊来预防失禁。在8个月的时间里，对306名计划进行钡剂灌肠检查的患者进行了评估。在每次检查前，将肛门括约肌张力评估为良好、中等或差。然后以传统方式进行钡剂灌肠。即使少量钡剂泄漏也被记为直肠失禁。保留钡剂灌肠的能力与直肠张力密切相关，与患者的性别或年龄无关。对于不同的括约肌张力，直肠失禁的发生率分别为：良好，2%；中等，30%；差，90%。根据这些发现，建议无论患者年龄和性别如何，直肠球囊导管的使用应仅限于直肠张力中等或较差的患者。
