The value of colonoscopy in the diagnosis and management of lower gastro-intestinal haemorrhage was assessed in 107 patients who were examined during a 2-year period. The main indications were to define uncertain radiological findings, to further investigate the cause of bleeding in patients with normal barium studies and to carry out polypectomy. Radiological lesions were confirmed in 27, defined in 12, and refuted in 14 patients. Twenty-eight lesions were demonstrated on colonoscopy which were not diagnosed by barium enema or sigmoidoscopy. A diagnosis was made by colonoscopy in more than two-thirds of the patients with frank blood loss and normal radiographs. In cases of occult bleeding it was farless helpful. Colonoscopy significantly improved diagnosis and management of gastro-intestinal bleeding when the cause was in doubt after standard investigations. In addition, 37 polyps were removed through the colonoscope from 30 patients.
在两年时间里对107例患者进行了检查，以评估结肠镜检查在下消化道出血的诊断和处理中的价值。主要适应证为明确不确定的放射学检查结果、进一步调查钡剂检查正常的患者的出血原因以及进行息肉切除术。27例患者的放射学病变得到证实，12例得以明确，14例被排除。结肠镜检查发现了28处钡剂灌肠或乙状结肠镜检查未诊断出的病变。在三分之二以上有明显失血且X线平片正常的患者中，结肠镜检查做出了诊断。在隐匿性出血的病例中，其帮助要小得多。当标准检查后病因仍存疑问时，结肠镜检查显著改善了胃肠道出血的诊断和处理。此外，通过结肠镜从30例患者身上切除了37个息肉。
