At low power, a central polypoid epithelial proliferation surrounded on both sides by ulcerated duodenal mucosa (
pseudopolyp).
Terminal ileum reports were available for 14 patients; 10 were positive (ulcers in seven patients and cobble-stoning in three; one of the 10 patients had erythema, narrowing, edema,
pseudopolyp and flat mucosa).
Hereby, WLE and CE accuracy showed superiority over NBI (64% and 63% versus 42%, resp.) in inflammation and
pseudopolyp histology prediction.

Large infiltration of inflammatory cells also requires identification of polyps associated with inflammatory bowel disease-related
pseudopolyp, filiform polyposis, etc.

Grossly there were no findings suggestive of prenatal DES exposure such as cervical hypoplasia,
pseudopolyp, or coxcomb deformity.
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.
D, Photomicrograph of hematoxylin-eosin-stained slide at low power showing a residual
pseudopolyp with surrounding ulceration mimicking inflammatory bowel disease (hematoxylin-eosin, original magnifications x400 [A and insets A], x40 [C], and x100 [D]; original magnification x200 [B]).
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.
