Factors Influencing Complication Rates at Colonic Polypectomy: A Prospective Study from a Tertiary-Referral Center


Background and aims. Colon polypectomy decreases the incidence of colorectal cancer and related mortality. Several factors such as the size, location and type of polyp as well as endoscopist experience have been shown to correlate with the risk of ensuing procedure-related complications. This study aims to evaluate the impact of polyp and endoscopist-related factors on the rate of postpolypectomy complication in a real-life setting.

Methods. During the study period all polypectomies performed in our unit were reported on a standard form that included data on polyp type (flat, sessile, pedunculated), size, location in the colon, resection method, endoscopist volume and procedure-related complications arising up to 30 days. The main outcome was the complication rate of polypectomies. The factors that associated with a higher risk of complications were assessed on univariate and multivariate analysis.

Results. 244 polyp resections from 95 patients were included in the analysis. 199 polyps were resected by low-volume endoscopists (44.7%) and 135 polypectomies were performed by highvolume endoscopists (55.3%). On multivariate analysis only polyp size correlated with the risk of procedure-related complications.

Conclusion. Polyp size is the most important risk factor for procedure-related complications. Both high and low-volume endoscopists have a low overall rate of serious complications.

Rapid fecal calprotectin testing predicts mucosal healing better than C-reactive protein and serum tumor necrosis factor α in patients with ulcerative colitis


Background and Aims. Serum and fecal biomarkers have been used as noninvasive methods for assessing disease activity in ulcerative colitis. C-reactive protein, serum tumor necrosis factor-α and fecal calprotectin are among the most promising such biomarkers. However, their role in the management of ulcerative colitis patients remains to be clarified. We aimed to evaluate the accuracy of C-reactive protein, fecal calprotectin and tumor necrosis factor-α in detecting clinical and endoscopic activity and predicting disease outcome.

Methods. A cohort of ulcerative colitis patients was prospectively evaluated for clinical and endoscopic disease activity using the Mayo score. Serum C-reactive protein and tumor necrosis factor-α levels were measured and a point-of-care method was used for determining Calprotectin levels.

Results. Fifty-three patients with ulcerative colitis were followed for a median of 12 months. Fecal calprotectin and C-reactive protein levels were significantly higher in patients with clinically active disease at baseline, but only calprotectin levels correlated with endoscopic activity. Calprotectin values over 300 μg/g had 60% sensitivity and 90% specificity for detecting active endoscopic disease and 61% sensitivity and 89% specificity for predicting mucosal healing.

Conclusion. Rapid calprotectin testing is a better predictor of mucosal healing than serum biomarkers and it could improve the management of ulcerative colitis patients by decreasing the need for invasive investigations.
