Safety and cost-effectiveness of outpatient colonoscopic polypectomy.

Background/aims: Factors that increase the complications arising from colonoscopic polypectomy have been well studied; however, data regarding complications from outpatient polypectomy is limited. The aim of this study was to identify the safety and costeffectiveness of outpatient colonoscopic polypectomy.

Methodology: Consecutive series of 804 patients who underwent colonoscopic polypectomy for 1,446 polyps were analyzed.

A prospective randomized study on computed virtual chromoendoscopy versus conventional colonoscopy for the detection of small colorectal adenomas.

Background: Colonoscopy is considered to be the standard diagnostic test for detecting colonic neoplasia, particularly for small lesions. However, recent publications have suggested that 15-27% of small adenomas might be missed during conventional colonoscopy.

Aims: To determine whether computed virtual chromoendoscopy (CVC) can improve the detection of small adenomas as compared to conventional colonoscopy.
