The Assessment of the Colo-rectal Polyps in Order to the New Diagnostic and Therapeutic Strategies

Abstract

Abstract Objective. Assessment of the histological and endoscopic features of the colo-rectal polyps is requered for the application of the new diagnostic and therapeutical strategies in the managment of the diminutive polyps. Methods. This paper is a descriptive retrospective study on 52 pacients reffered for colonoscopy in Gastroenterology Clinic – Clinical County Hospital Targu Mures from January until September 2014. 80 polyps were assessed. Narrow band imaging examination targeted on the protrusive lezions allowed NICE (Narrow Band Imaging International Colorectal Endoscopic) classification and corroboration of the histology prediction and pathological assessment. Results. Polyp detection rate was 48,58%, given the quality of bowel preparation in hospital fair in 84,5%. The predominant histological type was the tubular adenoma (46,25%), and 40% of the polyps were located in the sigmoid. Among the diminutive polyps, 58,33% were hyperplastic(p<0,0001), mainly in the recto-sigmoid (66,67%); the incidence of high grade displasia or cancer was 0. Real –time prediction of the histology of the colorectal polyps using NBI established: NICE 1: 19 polpyps, histology- 16 hyperplastic, (p<0,0001, sensitivity: 100%, specificity: 95%), NICE 2: 59 polyps, histology- 53 adenomatous, (p<0,0001, sensitivity: 96%, specificity: 76%), NICE 3: 2 polyps- histology-cancer. Conclusions. We did not observe any distribution pattern in the topography of the diminutive polyps. Histologicaly the predominant type was the hyperplastic type. NBI was accurate in real-time prediction of the histology of the colo-rectal polyps. The results are relevant for application of the new strategies in the managment of the diminutive polyps.
