Endoscopic ultrasonography for prediction of postpolypectomy @entity548 in @entity1 with large nonpedunculated XXXX .

@entity1 @entity652 @entity1127 @entity548 @entity6523 @entity2513
BACKGROUND AND STUDY AIMS: Case reports suggest that endosonographic visualization of blood vessels in a @entity1127 may be predictive of risk of postpolypectomy @entity548 ; however, this issue has never been studied in @entity1 with @entity2513 . @entity1 AND METHODS: Endosonography (EUS) was performed prior to endoscopic polypectomy of 42 large (>/= 20 mm) nonpedunculated @entity6523 . The median diameter of the @entity1127 was 30 mm (range 20-100 mm); 35 were located in the rectum and seven in the sigmoid colon. During EUS both the @entity1127 and the bowel wall underneath were searched for the presence of vessels, which were defined as longitudinal/tortuous or round/oval echo-free structures >/= 2 mm in diameter. RESULTS: The @entity1127 was visualized adequately in 39 cases; three cases were excluded from analysis due to inadequate visualization. In eight @entity1127 (20.5%, group 1) EUS revealed vessels measuring 2-4 mm; in 31 @entity1127 (79.5 %, group 2) no vessels were found. The postpolypectomy @entity548 incidence (per @entity1127 treated) was 12.5% in group 1 and 12.9 % in group 2 (P>0.05). CONCLUSIONS: In this small series of @entity1 with large nonpedunculated @entity652 , the EUS image of the @entity1127 was not predictive of postpolypectomy @entity548 . The detection of vessels on EUS did not increase the risk for @entity548 ; however, the sample size was to small to draw definite conclusions. The absence of vessels on EUS did not rule out the possibility of @entity548 .
