Abstract
Colonoscopy with polypectomy has been shown to reduce the risk of colon cancer development. It is considered a fundamental skill for all endoscopists who perform colonoscopy. A variety of polypectomy techniques and devices are available, and their use can vary greatly based on local availability and preferences. Polyps that are difficult to remove due to location or size require advanced resection techniques, such as endoscopic mucosal resection (EMR) and the use of special devices for safe and effective removal. However, colonic EMR is not routinely part of the standard endoscopic curriculum that is normally offered to gastroenterologists. It requires dedicated training in advanced endoscopic resection techniques, clinical and interpretive skills, and the knowledge and ability to manage complications.
The two most common post-polypectomy complications are bleeding and perforation. Their frequency can be limited with the use of meticulous polypectomy techniques and the application of some prophylactic manoeuvres.
This paper gives a review of the step by step technique of polypectomy and its complications from the perspective of the practicing gastroenterologist.
Ein schwieriger Polyp mit komplizierter Lage, Größe oder Form erschwert eine endoskopische Resektion und erhöht die peri- und post-interventionelle Komplikationsrate. Richtig angewendet können durch die endoskopische Mukosaresektion aber auch schwierige Polypen sicher endoskopisch entfernt werden.
