BACKGROUND Accurate optical diagnosis of small (<10 mm) colorectal polyps in vivo, without formal histopathology, could make colonoscopy more efficient and cost effective. The aim of this study was to assess whether optical diagnosis of small polyps is feasible and safe in routine clinical practice. METHODS Consecutive patients with a positive faecal(More)
BACKGROUND Despite its ubiquitous use over the past 4 decades, there is no structured, formal method with which to assess polypectomy. OBJECTIVE To develop and validate a new method with which to assess competency in polypectomy. DESIGN Polypectomy underwent task deconstruction, and a structured checklist and global assessment scale were developed(More)
BACKGROUND Colonoscopy reduces colorectal cancer mortality and morbidity principally by the detection and removal of colon polyps. It is important to retrieve resected polyps to be able to ascertain their histologic characteristics. OBJECTIVE The aim of the study was to evaluate the cause of polyp retrieval failure. DESIGN Bowel cancer screening(More)
BACKGROUND There is a gap in the formal assessment of technical skills in polypectomy that is now considered an integral part of colonoscopy. Polypectomy has been shown to reduce the incidence of colorectal cancer but does have associated complications. Polypectomy competency assessment should arguably be a part of the certification process for all(More)
INTRODUCTION Endoscopists are now expected to perform polypectomy routinely. Colonic polypectomy varies in difficulty, depending on polyp morphology, size, location and access. The measurement of the degree of difficulty of polypectomy, based on polyp characteristics, has not previously been described. OBJECTIVE To define the level of difficulty of(More)
BACKGROUND AND AIMS Variation in the adenoma detection rate (ADR) at flexible sigmoidoscopy screening has been shown to be due to variation in endoscopist performance. There are no objective methods for scoring an endoscopist's performance reliably, and the aim of this study was to develop a valid and reliable objective scoring method using video footage of(More)
AIM St Mark's Bowel Cancer Screening Centre commenced screening in October 2006 as a contributor to the national programme. The first 35 months' experience is reported. METHOD Individuals with a positive faecal occult blood test (FOBT) were offered colonoscopy or alternatives if they had significant comorbidity. All screening data were collected(More)
Few studies have compared the efficacy of the Picture Exchange Communication System (PECS) and iPads used as speech generating devices (SGDs), and none have targeted preschoolers. This study compares the relative efficacy of PECS and an iPad/SGD with three preschool-aged children with autism spectrum disorder and limited functional speech who lived in(More)
