Diagnoses suggested for these cases by the referring pathologist included giant fibrovascular polyp (4 cases) and ‘spindle cell neoplasm’ (1 case). All tumors presented as pedunculated ...

A pedunculated polyp (Panel A) being removed with a snare around its short stalk (Panel B). Reproduced with permission from Hans Bjorknas (www.gastrolab.net). Colonic adenomas are typically ...

Sessile polyps are considered precancerous. They’re typically removed during a colonoscopy or follow-up surgery. Pedunculated polyps are the second shape. They grow on a stalk up from the tissue.

Large pedunculated polyps (> 2-3 cm) are often easily removed with standard snare cautery techniques. The difficulty most commonly encountered is when a large polyp has a particularly long stalk ...

The researchers found that 10.1 percent of the 346 neoplastic polyps (269 patients; 84.0 percent men; mean age, 63.4 years) removed by 11 gastroenterologists were incompletely resected.

T1 colorectal cancer can be mimicked by pseudo-invasion in pedunculated polyps. British guidelines are currently one of the few which recommend diagnostic confirmation of T1 colorectal cancer by a ...

Exclusion criteria were recurrent lesions with previous EMR; lesions diagnosed as deeply submucosal invasive cancer by colonoscopy; non-neoplastic polyps; or pedunculated polyps. Only protruded ...

EMR, the standard approach for large, non-pedunculated polyps, utilizes submucosal injection to create a cushion, allowing for safer and more complete resection with a snare. ESD, a more advanced ...

Crockett and colleagues randomly assigned patients with large ( 20 mm) non-pedunculated polyps who underwent endoscopic mucosal resection to either clipping of the resection base or no clipping.

In addition to being used to create traction in ESD, the +DR System can be attached to a large pedunculated polyp via a detachable snare to ‘pull’ the polyp aside and expose the stalk.
