A 49-year-old man was referred for colonoscopy after a positive fecal occult blood test. Laboratory tests and physical examination were unremarkable but colonoscopy revealed a large pedunculated polyp in the sigmoid colon (●" Fig.1). Owing to inadequate bowel cleansing, polypectomy was not carried out. On repeat colonoscopy 120 days later, bowel cleansing was excellent. The examination was perf...
BACKGROUND Colorectal polyps (CP) are common among individuals older than 50 years. Some polyp types can precede colorectal cancer (CRC). This study aimed at describing histopathological characteristics of colorectal polyps in relation to age and gender among symptomatic patients referred for a colonoscopy examination during 2011-2014 in Tirana, Albania. METHODS Study population included 267 ...
Analysis of two human familial cancer syndromes, hereditary nonpolyposis colorectal cancer and familial adenomatous polyposis, indicates that mutations in either one of four DNA mismatch repair gene homologues or the adenomatous polyposis coli (APC) gene, respectively, are important for the development of colorectal cancer. To further investigate the role of DNA mismatch repair in intestinal tu...
Cervical polyps are a common pathology in the female adult population. Giant cervical polyp is described as a polyp greater than 4cm in size and is rarely seen in clinical practice. The size and clinical presentation mimic neoplasia. So far only 14 cases of giant cervical polyps have been reported in medical literature, which are mostly single. We report a case of multiple giant cervical polyps...
OBJECTIVE To investigate the success rate of cold snare polypectomy (CSP) for complete resection of 4-9 mm colorectal adenomatous polyps compared with that of hot snare polypectomy (HSP). DESIGN A prospective, multicentre, randomised controlled, parallel, non-inferiority trial conducted in 12 Japanese endoscopy units. Endoscopically diagnosed sessile adenomatous polyps, 4-9 mm in size, were r...
Min (Multiple intestinal neoplasia) mice carry a dominant mutation in the adenomatous polyposis coli (Apc) gene and develop multiple adenomas throughout their intestinal tract (Moser et al. 1990; Su et al 1992). Polyp multiplicity in Min mice is greatly influenced by genetic background. A modifier locus, Mom1 (Modifier of Min 1), was identified and localized to distal mouse chromosome 4 (Moser ...
AIM The biology of colorectal hyperplastic polyps is of considerable relevance, because recent evidence suggests that under certain circumstances hyperplastic polyps may be precursors of neoplasms. The aim of this study was to assess and compare the clinical and molecular characteristics of hyperplastic polyps and neoplastic lesions removed from patients without the hyperplastic polyposis syndr...
BACKGROUND The appropriate application of Endoscopic modalities for polypectomy depends on the likelihood that the adenoma in question harbors invasive cancer. While prior studies have evaluated polyp size and morphology in assessing the risk of malignancy, in recent decay some authorities have paid more attention to dysplasia. All in all, the relative risk of cancer based on polyp distribution...
A FEW decades ago intestinal polyposis was regarded as a single entity, but increasing knowledge has led to the identification of a number of different syndromes. The term polyposis coli is usually taken to mean familial adenomatosis coli, a premalignant condition occurring in adolescents and adults. Although there have been many reports of colonic polyposis in children, discussions on the subj...
In vivo real-time assessment of the histology of diminutive (≤5 mm) colorectal polyps detected at colonoscopy can be achieved by means of an "optical biopsy" by using currently available endoscopic technologies. This systematic review and meta-analysis was performed by the American Society for Gastrointestinal Endoscopy (ASGE) Technology Committee to specifically assess whether acceptable perfo...
