The endoscopic appearance may reveal a sessile or pedunculated polyp
with or without surface ulceration ranging in size between 5 mm and 27 mm.
Via an antrotomy the pedunculated polyp
measuring 4.5cm was resected (figure 2B).
Upon colonoscopy, a 2 cm pedunculated polyp
was identified in the transverse colon.
Considering the presence of benign pedunculated polyp
in the patient, no preoperative imaging was performed.
This high N1 rate maybe due to the fact that none of the patients in this study had simple snare polypectomy of a simple pedunculated polyp
. All their patients were found after EMR indicating that these patients had large, flat, or sessile polyps and thereby more complex polyps than simple pedunculated polyps
Observation acceptable (controversial) Size <0.5 cm and patient is not symptomatic PLGs: Polypoid lesions of the gallbladder Table 2.
Macroscopic examination of the resected ileal segment found a 3 x 3 x 3 cm firm pedunculated polyp
projecting into the bowel lumen (Figure 2).
The root of polyp was approached by trephining on dorsolateral aspect of nasal bone and pedunculated polyp
growth was extirpated from nasal cavity (Fig1,2,3).
The Mexican hat sign is formed by the appearance of 2 concentric rings; the outer ring represents the "en face" visualization of barium coating the surface of the head of a pedunculated polyp
, while the inner ring represents a meniscus of barium surrounding the stalk of the polyp visualized through the head (Figure 21).
After a Kocher manoeuvre and duodenotomy, a pedunculated polyp
, 2x2cm in size, was found on the second portion of the duodenum with active bleeding, and the polypectomy was performed (Fig.2).
Nasoendoscopy in the ear, nose and throat clinic showed a large pedunculated polyp
originating under the right vocal cord (Figure 1) occupying approximately 60 to 80% of the airway circumference, moving in and out of the larynx with respiration.
Videostroboscopic examination detected a huge pedunculated polyp
arising from the free edge of the right true vocal fold.
