Therapeutic and Diagnostic Approaches in Colonoscopy

چکیده
Colorectal cancer is a common gastrointestinal malignancy in the USA, Europe, and Japan. Most colorectal cancers are thought to arise from preexisting adenomas based on the concept of the adenoma-carcinoma sequence [1]. Chromoendoscopy, using Kudo and Tsuruta’s pit pat‐ tern classification, is an efficient tool for the differential diagnosis of colorectal polyps [2-4]. Re‐ cently, image-enhanced endoscopy (IEE) has been used for diagnosing gastrointestinal tumors [5-7]. Endoscopic therapy, including endoscopic mucosal resection (EMR) and endoscopic sub‐ mucosal dissection (ESD), is used worldwide to treat adenoma and early colorectal cancer [8-10]. In this chapter, we demonstrated the effectiveness of IEE and discuss strategies of thera‐ peutic endoscopy including EMR and ESD.
