Between April 1975 and December 1985, 870 colonoscopies have been performed at Wellington Hospital. A cause of gastrointestinal blood loss was identified in 61% of patients examined for this reason. Ninety-eight percent of patients with longstanding total mucosal ulcerative colitis were able to be managed nonsurgically. The diagnostic problem was resolved colonoscopically in 99% of patients with radiological abnormality. Seven hundred and seventy-six polyps and four polypoid carcinomata were removed endoscopically. A further four patients were referred for surgery following incomplete removal of polypoid carcinomata but no residual tumour was found in the resected bowel. It is suggested that strict criteria be employed in the selection of patients for colonoscopy.
1975年4月至1985年12月期间，惠灵顿医院共进行了870例结肠镜检查。因该原因接受检查的患者中，61%被确定存在胃肠道失血病因。98%的长期全黏膜溃疡性结肠炎患者能够通过非手术方式治疗。99%有放射学异常的患者通过结肠镜检查解决了诊断问题。经内镜切除了776颗息肉和4例息肉样癌。另有4例患者在息肉样癌切除不完全后被转诊接受手术，但在切除的肠段中未发现残留肿瘤。建议在选择结肠镜检查患者时采用严格标准。
