pseudopolyp

pseudopolyp

 [soo″do-pol´ip]
a hypertrophied tab of mucous membrane resembling a polyp, but caused by ulceration surrounding intact mucosa.

(sū'dō-pol'ip),
A projecting mass of granulation tissue, large numbers of which may develop in ulcerative colitis; may become covered by regenerating epithelium.
Synonym(s): inflammatory polyp

pseudopolyp

(so͞o′dō-pŏl′ĭp)
n.
A projecting mass of granulation tissue, such as the masses that may develop in ulcerative colitis.

pseudopolyp

An “island” of preserved colonic mucosa, surrounded by haemorrhagic ulcerated mucosa. Pseudopolyps are typical of ulcerative colitis, but may be seen in nonspecific inflammatory bowel disease, bacterial dysentery, amoebiasis due to Entamoeba histolytica and schistosomiasis.

SAN DIEGO -- A "suction pseudopolyp" technique is safe and effective for removing flat or nearly flat colorectal polyps, according to a study presented at the annual Digestive Disease Week.
Radiologic characteristics mainly included involvement of [less than or equal to] 3 segments, thickening bowel wall, asymmetrical pattern of involvement, intraluminal pseudopolyp formation, target sign, circumintestinal exudation, stricture with proximal dilation, comb sign, fistula, abscess, phlegmon, and ascites.

For the rubber band technique, the tissue suctioned into the cap is grasped by deploying a rubber band forming a "pseudopolyp." The banded "pseudopolyp" containing the tumor is then cut with a snare at its base, ensuring that some of the uninvolved surrounding mucosa and/or submucosa is attached to the tumor.
This results in a pseudopolyp that can be immediately captured by forcefully closing the endoscopic snare.
