Nine patients with clinical or radiographic evidences of bowel obstruction were examined by magnetic resonance imaging. Retrograde insufflation of 1000-1200 ml of air through a Foley catheter placed in the rectum was employed. Scopolamine was used to inhibit bowel peristalsis and possibly relax the ileocecal valve. The administered air successfully distended the colon and the small bowel distal to the obstruction in seven of the nine cases. The air-filled small bowel loops were useful in delineating the obstruction sites and adjacent lesions in these seven cases. The diagnosis was established by means of surgery in six cases and by clinical course in three cases. The causes of obstruction included four peritoneal carcinomatoses, and one each of supravesical hernia, intussusception, adhesive band, benign granulomatous stricture, and radiational stricture. The site of obstruction was the distal small bowel in eight cases, and the rectosigmoid colon in one case.
对9例有肠梗阻临床或影像学证据的患者进行了磁共振成像检查。通过置于直肠的Foley导管逆行注入1000 - 1200毫升空气。使用东莨菪碱抑制肠道蠕动并可能松弛回盲瓣。在9例患者中的7例中，注入的空气成功使结肠和梗阻远端的小肠扩张。在这7例中，充满空气的小肠袢有助于确定梗阻部位和相邻病变。6例通过手术确诊，3例通过临床病程确诊。梗阻原因包括4例腹膜癌，1例分别为膀胱上疝、肠套叠、粘连带、良性肉芽肿性狭窄和放射性狭窄。梗阻部位在8例中为小肠远端，1例为直肠乙状结肠。
