Purpose Because data as a basis for the determination of proper age and modality for screening of colorectal neoplasms is lacking, we evaluated detection rates and anatomical distribution of colorectal neoplasms according to age in healthy individuals who underwent total colonoscopy for health checkup. Methods A total of 16,100 cases that had received the colonoscopic examination from January...

BACKGROUND Some authors have studied the relationship between the presence of polyps, adenomas and cancers of upper gastrointestinal tract (stomach and duodenum) and risk of colorectal polyps and neoplasms; however, the results are controversial, which may be due to study sample size, populations, design, clinical features, and so on. No meta-analysis, which can be generalized to a larger popul...

Endoscopic submucosal dissection (ESD) has been applied to, and gradually standardized for, early gastric cancers; however, it has not yet been widely used for treatment of colorectal neoplasms. Compared with gastric ESD, the thinner colorectal wall and winding nature of the colon make colorectal ESD a much more difficult operative technique. Despite greater risks of postoperative complications...

PURPOSE The association between stomach cancer and colorectal cancer is controversial. The purpose of this study was to determine the synchronous prevalence of colorectal neoplasms in patients with stomach cancer. METHODS A total of 123 patients with stomach cancer (86 male) and 246 consecutive, age- and sex-matched persons without stomach cancer were analyzed from July 2005 to June 2010. All...
