在准备进行结肠镜检查的患者中，使用灵活的pH探头测量结肠内特定解剖节段的粘膜pH值。数据显示，无论是否有结直肠肿瘤，沿着结肠长度的PH值测量结果相似。患者表现为相对酸性的右半结肠，较碱性的横结肠、左半结肠和乙状结肠，以及相对酸性的直肠。对结肠粘膜的pH值没有明显的性别或年龄相关影响。
Mucosal pH was measured at specific anatomic segments within the colon using a flexible pH probe in patients prepared for colonoscopy. The data revealed similar pH measurements along the length of the colon, irrespective of the presence or absence of colorectal neoplasia. Patients exhibited a relatively acidic right colon; a more alkaline transverse, left, and sigmoid colon; and a relatively acidic rectum. There were no apparent gender- or age-related effects on colonic mucosal pH.
