Abstract

The reproducibility of a method of measuring rectal distensibility by continuous controlled fluid inflation with a balloon has been evaluated in 15 patients. The volume at sensation threshold, constant sensation and maximal tolerance, the pressures at these volumes and rectal compliance were measured. The mean coefficients of variation of the seven variables measured ranged from 4.7%-7.9%. The expected correlation between rectal compliance and maximal tolerable volume was confirmed (r = 0.85, p less than 0.001). The high reproducibility makes this investigation reliable for use in clinical practice and research.

摘要

通过用球囊进行连续控制液体充气来测量直肠扩张性的一种方法的可重复性,已在15名患者中进行了评估。测量了感觉阈值、恒定感觉和最大耐受性时的容积,这些容积时的压力以及直肠顺应性。所测量的七个变量的平均变异系数在4.7%-7.9%之间。证实了直肠顺应性与最大可耐受容积之间的预期相关性(r = 0.85,p < 0.001)。高可重复性使得这项研究在临床实践和研究中使用时具有可靠性。
