BACKGROUND It has been postulated that the occurrence of invasive carcinoma in a colon adenoma can be predicted by estimating the size of the resected polyp. Recently, significant intra- and inter-observer differences in size were found when 22 pathologists estimated the size of 12 polyp phantoms. In this work, the size of a large cohort of endoscopically-resected colon polyps was assessed with...

Purpose Colonic diverticulitis is uncommon in Korea, but the incidence is rapidly increasing nowadays. The clinical features and the factors associated with complications of diverticulitis are important for properly treating the disease. Methods A retrospective review of the medical records of 225 patients that were prospectively collected between October 2007 and September 2016 was conducted...

In addition to understand how colonic hydrotherapy is perceived by those who use it and how much economic benefit it generates for the practitioners. Information as to training and complications was sought. PATIENTS AND METHO...

One important purpose of conducting gene expression experiments is to understand the correlation of gene expression profiles to disease states. Based on the notion of emerging patterns and an entropy-oriented discretization method, we discover groups of genes that are correlated to disease states in a significant way. In each group, every member gene constrained by a specific expression interva...

introduction: functional constipation is one of the most common gastrointestinal symptoms which could affect patients’ quality of life. the colonic transit time test could be used for determining functional constipation subtypes. the aim of our study was to determine the abnormalities of the subtypes of functional constipation using ctt. methods and materials: this cross-sectional study was per...

objective(s):the aim of this study was to prepare electrospun nanofibers of celecoxib using combination of time-dependent polymers with pectin to achieve a colon-specific drug delivery system for celecoxib. materials and methods:formulations were produced based on two multilevel 22 full factorial designs. the independent variables were the ratio of drug:time-dependent polymer (x1) and the amoun...

A prospective study with two gastric biopsies taken several years apart was carried out in 117 subjects with intestinal metaplasia who are of the Lewis(a-b+) phenotype. They are residents of a rural Andean region in Colombia displaying very high rates of gastric cancer. The anomalous expression of Lewis(a) antigens in the metaplastic epithelium carried a significantly increased risk of colonic ...

BACKGROUND Population-based epidemiologic studies about colorectal cancer are lacking in China. This study aims to provide a basis for colorectal cancer screening and prevention, through analysis and comparisons the characteristics of the trends in colorectal cancer incidence in Beijing and selected representative regions. RESULTS The annual incidence rate in Beijing region increased signific...
