Introduction:
Patients with large non-pedunculated colorectal polyps (L-NPCP) have been traditionally treated with surgery. Advances in therapeutic endoscopy allow endoscopic resection of these lesions and can be considered as an alternative to surgery.
Objective:
To evaluate the efficacy and safety of endoscopic resection in patients with L-NPCP.
Methods:
A prospective multicentric cohort. All patients referred for endoscopic resection with L-NPCP between January 2012 and December 2015, followed until August 2016, were included. Rates of successful resection, recurrence and complications were obtained. Predictive factors associated with unsuccessful resection and recurrence were analyzed.
Results:
115 L-NPCP in 107 patients were included. The rate of successful resection was 92%. The most common complications were bleeding (8.7%) and perforation (2.6%). The recurrence rate was 7%, all successfully treated with a new endoscopic session. Predictors of unsuccessful resection were a measure >50 mm of the lesion and the presence of fibrosis; and the only predictor of recurrence was a size of the polyp resected >50 mm.
Conclusions:
Endoscopic resection of L-NPCP is very efficacious and safe.
