为探讨x线电视(TV)透视下空气灌肠对拟诊为急性结肠梗阻患者的早期诊断价值,笔者选取无腹部手术病史、肛查为阴性、腹部立位片提示急性结肠梗阻的患者36例。在x线TV透视下经Foley双腔导尿管注入压力为60mmHg～90mm Hg的空气,然后观察空气影像。结果示31例空气影像在结、直肠不同部位受阻,手术均证实为结、直肠癌梗阻;其中33例(91.7%)肿瘤位置与空气灌肠梗阻部位一致。4例为小肠梗阻。1例乙状结肠扭转。提示空气灌肠x线TV透视有利于急性结肠梗阻的早期定位诊断,对肠套叠及扭转有相对的定性诊断价值。该方法操作简单、安全、实用,对后期电子肠镜检查无影响。
In order to investigate the early diagnosis value of air enema under X-ray (TV) fluoroscopy on patients diagnosed as acute colonic obstruction, the author chose no history of abdominal surgery, negative anal examination and 36 cases of patients with acute colonic obstruction. The air pressure of 60mmHg ~ 90mm Hg was injected through the Foley double-lumen catheter under x-ray fluoroscopy and then the air image was observed. The results showed that 31 cases of air images were blocked in different parts of the knot and rectum, and the operation was confirmed as colorectal cancer obstruction; 33 (91.7%) tumor sites were consistent with the air enema obstruction site. 4 cases of small bowel obstruction. One case of sigmoid colon torsion. Tip air enema x-ray fluoroscopy is conducive to the early diagnosis of acute colon obstruction diagnosis of intussusception and torsion relative qualitative diagnostic value. The method is simple, safe and practical, no effect on the late colonoscopy.
