Sixty five of 70 consecutive patients with undiagnosed gastrointestinal blood loss were examined using the new technique of small bowel enteroscopy. Using a balloon driven sonde enteroscope (SIF-SW) extended views of the small bowel were obtained as far as the distal ileum. Medium length of small bowel examined was 140 cm (range (30-200 cm). All patients studied had a normal upper gastrointestinal endoscopy. Nineteen (41%) of 46 anaemic rheumatoid arthritis patients taking non-steroidal antiinflammatory drugs (NSAID) and three (27%) of 11 patients with unexplained iron deficiency, were found to have small bowel lesions to account for their anaemia. Small bowel lesions were found in a further three of eight (37%) patients with acute gastrointestinal bleeding. The procedure failed or was terminated in five patients. Small bowel enteroscopy has considerable potential in the investigation of undiagnosed gastrointestinal blood loss and deserves more widespread application.
对70例连续的不明原因胃肠道失血患者中的65例，采用小肠肠镜检查新技术进行了检查。使用气囊驱动的探头式小肠镜（SIF-SW），可观察到小肠直至回肠末端的扩展视野。检查的小肠平均长度为140厘米（范围30 - 200厘米）。所有接受研究的患者上消化道内镜检查均正常。46例服用非甾体抗炎药（NSAID）的贫血类风湿关节炎患者中有19例（41%），11例不明原因缺铁患者中有3例（27%），发现小肠病变可解释其贫血原因。另外，8例急性胃肠道出血患者中有3例（37%）发现小肠病变。该检查程序在5例患者中失败或终止。小肠肠镜检查在不明原因胃肠道失血的调查中具有相当大的潜力，值得更广泛应用。
