Diagnostic role of combined chromo- and zoom colonoscopy in asymptomatic patients with genetic predisposition of familiar adenomatosus polyposis syndrome

Introduction: Combined chromo- and zoom colonoscopy is proposed to improve the detection efficacy of small colorectal polyps and to differentiate between hyperplastic, adenomatosus and dysplastic polyps. The aim of the present study was to investigate young, asymptomatic but genetically predisposed members of FAP families by means of chromo- and zoom colonoscopy. Methods: During the year of 2005, we performed chromo- and zoom colonoscopy in three individuals (3 female, mean age: 27 years), all were genetically predisposed to FAP. Colonoscopy was performed with the Olympus zoom colonoscopy (CZ- 160i). Each 20cm l…
