自20世纪六十年代末结肠镜检査术问世以来,无论是其操作手法还是器械改革均得到飞速发展,并广泛应用于临床,使直视病灶、实现活检及治疗成为可能。虽然,结肠镜检查为结直肠疾病的诊断及治疗带来了巨大的帮助并成为结直肠癌诊断的金标准,但其局限性也日渐明显。作为一种侵入性操作,结肠镜检查无法避免的腹部疼痛、难以预知的并发症、无法保证的成功率以及可能存在的漏诊率限制了其临床应用不仅在一定程度上降低了患者的依从性,增加了操作的困难度,且使一部分具有操作指征的患者错失早期诊断及治疗的最佳时机。本文简要阐述了传统注气式结肠镜检查法的一般特点并总结了其应用现状,以期为今后传统注气式结肠镜检查法的合理化应用提供一定的参考依据。
Since the advent of colonoscoposcopy in the late 1960s, both its manipulation practices and instrumental reforms have been rapidly developed and are widely used in clinical settings to make it possible to visualize lesions and perform biopsy and treatment. Although colonoscopy has brought tremendous help in the diagnosis and treatment of colorectal diseases and become the gold standard for the diagnosis of colorectal cancer, its limitations are becoming increasingly apparent. As an invasive procedure, the unavoidable pain in the abdomen, the unpredictable complications of colonoscopy, the unacceptable success rate, and the possible misdiagnosis limit its clinical application not only to a certain extent reduce patient compliance, Increase the difficulty of operation, and make a part of patients with operation indications missed the best time for early diagnosis and treatment. This article briefly describes the general characteristics of the traditional gas-jet colonoscopy and summarizes its application status, with a view to provide some reference for the future rational use of gas-jet colonoscopy.
