The width of the presacral space was measured prospectively at various levels in 100 persons without organic colonic or rectal disease who had barium enema X-ray examinations. A standard technique was employed. The most consistent measurement was obtained at the level opposite the S3-S4 disc space; readings varied between 2 mm and 16 mm. Using 16 mm as the upper limit of normal, and a similar technique of barium enema examination, the width of the presacral space at the S3-S4 disc level was measured in 66 patients with inflammatory bowel disease (ulcerative colitis--49; Crohn's colitis--17). The width did not correlate with the severity of the disease process as indicated by sigmoidoscopic examination in proximity in time to the radiological examination. There was a relationship between increased width of the presacral space and the duration of the disease process.
对100名接受钡剂灌肠X线检查且无器质性结肠或直肠疾病的患者，前瞻性地测量了不同水平的骶前间隙宽度。采用了标准技术。在S3 - S4椎间盘间隙相对水平获得的测量结果最一致；读数在2毫米至16毫米之间。以16毫米作为正常上限，并采用类似的钡剂灌肠检查技术，对66例炎症性肠病患者（溃疡性结肠炎——49例；克罗恩结肠炎——17例）测量了S3 - S4椎间盘水平的骶前间隙宽度。该宽度与在放射学检查时临近的乙状结肠镜检查所显示的疾病严重程度无关。骶前间隙增宽与病程长短之间存在关联。
