Endoscopic resection of large pedunculated colon polyps using only a scissor-type knife: a case series
All pedunculated colon polyps (PCPs) should ideally be resected en bloc for accurate histopathological evaluation. However, maneuvering a snare around the large head of a pedunculated polyp with a long, wide stalk can be technically challenging. In addition, clinically significant bleeding after snare polypectomy remains a legitimate concern. Small case series from Asia have supported the feasibility of endoscopic submucosal dissection (ESD) for the removal of these challenging large PCPs. However, ESD is not widely performed in the West because of its technical complexity, steep learning curve, and higher risk of adverse events when compared with conventional endoscopic mucosal resection.Tissue retractor system–assisted endoscopic submucosal dissection of a large rectal tumor with significant fibrosis from direct tattooing
Endoscopic tattooing directly into large dysplastic lesions is often performed for lesion identification before EMR or endoscopic submucosal dissection (ESD). Several case reports have demonstrated the difficulty of attempting endoscopic resection of previously tattooed lesions, primarily because of tattoo-induced submucosal fibrosis, inadequate lifting of the lesion, and obscuring of the dissection planes.1-3
