Abstract:

In recent years, with the development of endoscopic technology and the continuous enhancement of national health awareness, colonoscopy has made great progress in screening, diagnosis and treatment of colon diseases. However, with the enrichment of these diagnosis and treatment methods, the incidence of full-thickness defects under colonoscopy has gradually increased, including passive perforation during colonoscopy, pre judged, prepared defects and non predicted intestinal defects before colonoscopy treatment, which has gradually become the bottleneck of the development of endoscopic treatment. Therefore, various advanced endoscopic sealing technologies or devices have been developed and used, which play an important role in the treatment of full-thickness intestinal defects and provide guarantee for the wide application of endoscopic diagnosis and treatment technology. This paper summarizes the existing colonoscopy sealing technology, and discusses its advantages and limitations in the treatment of full-thickness intestinal defects.

Key words: Colonoscopy, Full thickness defect, Over-the-scope clip system(OTSC), Endoscopic suture device
