Abstract：
OBJECTIVE: To evaluate the impact of two different parameters (body position and distension medium) on the rectal sensory test in patients with functional constipation and provide data support for the development of standardized operating procedures in clinical practice.
METHODS: Based on a single-center process of the rectal sensory test, 39 patients with functional constipation were recruited for rectal sensory test under different body positions and distension mediums.
RESULTS: Among the items of the Constipation Scoring System, the score of frequency of bowel movements showed a negative correlation with the first constant sensation volume (r = -0.323, P = 0.045). Conversely, the score of painful evacuation effort showed a positive correlation with the desire to defecate volume (r = 0.343, P = 0.033). There was a statistically significant difference in the first constant sensation volume (when the distension medium was gas) measured in different body positions (left lateral position, sitting position, squatting position), and the data measured in the squatting position were significantly higher than those in left lateral position (P < 0.05). In terms of research on distension medium, it was found that the first constant sensation volume measured in the squatting position (when the distension medium was water) was significantly lower than that of gas (P < 0.05).
CONCLUSIONS: For patients with functional constipation, there are differences in the results of rectal sensory tests between body positions and distension mediums. When conducting multicenter studies, it is necessary to unify the standard operating procedure (SOP) for operational details to ensure consistency and reliability of the test results.

摘要：
目的：评估两种不同参数（体位和扩张介质）对功能性便秘患者直肠感觉测试的影响，为临床实践中标准化操作程序的制定提供数据支持。
方法：基于直肠感觉测试的单中心过程，对39例功能性便秘患者在不同体位和扩张介质下进行直肠感觉测试。
结果：在便秘评分系统的项目中，排便次数评分与第一恒定感觉量呈负相关(r=-0.323,P=0.045)。相反，疼痛性疏散努力得分与排便欲望呈正相关（r=0.343，P=0.033）。在不同体位（左侧卧位，坐姿,蹲下位置)，蹲位测量的数据明显高于左侧卧位（P<0.05）。在膨胀介质的研究方面，发现在下蹲位置（当膨胀介质为水时）测得的第一恒定感觉量明显低于气体（P<0.05）。
结论：对于功能性便秘患者，体位和扩张介质之间的直肠感觉测试结果存在差异。在进行多中心研究时，有必要统一标准操作程序（SOP）的操作细节，以确保测试结果的一致性和可靠性。
