Gallbladder polyps are growing masses inside the wall of the gallbladder. In the majority of patients, the diagnosis represents an incidental finding of a routine abdominal u l t rasonography, or fo l lowing cholecystectomy for gallstones. The overwhelming majority of these lesions are non-neoplastic therefore called as pseudo-tumor. The widespread use of ultrasonography has made the diagnosis ...

BACKGROUND & AIMS High-risk features of colonic polyps are based on size, number, and pathologic characteristics. Surveillance colonoscopy is often recommended according to these findings. This study aimed to determine whether the molecular characteristics of polyps might provide information about the risk of metachronous advanced neoplasia. METHODOLOGY We retrospectively included 308 patient...

Under the term endometrial polyps is grouped a variety of tumors of polypoid structure which are attached to the inner uterine wall by pedicles of variable length and thickness. Although their histologic characteristics differ greatly, the most common variety has a tissue structure similar to that of the surrounding endometrium. The polyps may be single or multiple; small, or large enough to oc...

PURPOSE To identify the prevalence, types, and patterns of colonic polyps in a cohort of patients presenting to a tertiary care referral center in Sri Lanka. METHODS Endoscopy and pathology reports of a single unit from 2006 to 2013 were analyzed retrospectively. Spearman's correlation coefficient and chi-square test were used to identify correlations. RESULTS There were a total of 158 pati...

BACKGROUND AND AIMS High-resolution microendoscopy (HRME) is a novel, low-cost "optical biopsy" technology that allows for subcellular imaging. The study aim was to evaluate the learning curve of HRME for the differentiation of neoplastic from non-neoplastic colorectal polyps. METHODS In a prospective cohort fashion, a total of 162 polyps from 97 patients at a single tertiary care center were...

BACKGROUND Hereditary mixed polyposis syndrome is characterised by multiple large-bowel polyps of differing histological types including a mixture of atypical juvenile polyps, hyperplastic polyps and adenomas. Affected individuals are thought to have an increased risk of malignancy, possibly via the juvenile polyposis pathway. METHODS A 51-year-old woman (with a history of a colectomy for pol...

Using a case-control design, we evaluated differences in risk factors for colorectal polyps according to histological type, anatomical site, and severity. Participants were enrollees in the Group Health Cooperative aged 20-79 years who underwent colonoscopy in Seattle, Washington, between 1998 and 2007 and comprised 628 adenoma cases, 594 serrated polyp cases, 247 cases with both types of polyp...
