最近研究表明,细口径内窥镜及配合使用辅助装置可提高盲肠插管率、提高盲肠插管时间、提高病变检出率及减轻腹痛,国外一些研究者将除结肠镜以外的消化内镜用于困难结肠镜,结果表明对于普通肠镜无法完成的结肠检查,可考虑使用其它内镜。本研究以“普通肠镜无法完成的结肠检查”定义为困难结肠镜,进一步阐明细口径内窥镜及配合使用辅助装置用于困难结肠检查的优势。 Recent studies have shown that the use of small-caliber endoscopes and auxiliary devices can improve the cecal intubation rate, improve the cecal intubation time and improve the detection rate of lesions and reduce abdominal pain, some foreign researchers will be in addition to colonoscopy digestive endoscopy In difficult colonoscopy, the results show that for ordinary colonoscopy colonoscopy can not be completed, consider the use of other endoscopy. This study, defined as a difficult colonoscopy with “colonoscopy that can not be performed with ordinary colonoscopy”, further illustrates the advantages of a slim-bore endoscope and the use of assistive devices in difficult colon examinations.
