Endometrial polyps are benign localized lesions of the endometrium, which are commonly seen in women of reproductive age. Observational studies have suggested a detrimental effect of endometrial polyps on fertility. The natural course of endometrial polyps remains unclear. Expectant management of small and asymptomatic polyps is reasonable in many cases. However, surgical resection of endometri...

The aim of the present study was to evaluate estrogen receptor (ER) and progesterone receptor (PR) expression in the glandular epithelium and stroma of benign and malignant endometrial polyps of postmenopausal patients. A total of 1,050 females underwent surgical hysteroscopy at the Professor Dr José Aristodemo Pinotti Women's Hospital, Center for Integral Attention to Women's Health of the Sta...

Background Juvenile polyps, classified as hamartomatous lesions with neoplastic potential, are the most common gastrointestinal polyp of childhood. Risk factors for neoplasia include germline DNA mutations, a family history of juvenile polyps, and multiple polyps (≥3 or ≥5). Only a few large pediatric series (>100patients) of patients with juvenile polyps have been reported, with limited data a...

The stomach is far less rich in polyps than is the colon. As a result, we know much less about gastric polyps than colonic polyps, and the literature tends to be much more recent and sparser. About 5 to 10% of biopsies of endoscopic gastric polyps are normal mucosa. The reasons for this include the biopsy forceps missing the lesion, an intramural lesion that is not available to endoscopic biops...

AIMS To determine whether an adequate histological diagnosis of gastric polyps can be attained on the basis of forceps biopsy. PATIENTS AND METHODS In a prospective multicentre study, 194 patients with 222 endoscopically removable gastric polyps (>or=5 mm) underwent forceps biopsy and complete polypectomy. Patients with fundic gland polyps and polyposis syndrome were not included. Specimens w...

Background and aims: Colorectal adenomas are recognised as precursors of colorectal carcinomas. The significance of hyperplastic (metaplastic) colorectal polyps is unknown. The relationship between hyperplastic polyps and adenomas, and the prevalence and incidence of these lesions were evaluated in individuals predisposed to familial colorectal cancer. Methods: A total of 299 individuals partic...

BACKGROUND AND AIMS  Colorectal cancer (CRC) is associated with a significantly reduced survival rate in transplant recipients. The prevalence and risk factors of CRC and of colorectal polyps after orthotopic liver transplant (OLT) remain unclear. The study aim was to determine the prevalence of colorectal polyps in OLT recipients. A secondary objective was to explore possible risk factors of p...

Purpose. To investigate the prevalence and risk factors of hyperplastic and adenomatous colorectal polyps in a Taiwanese general population. Methods. From January 2009 to December 2011, consecutive asymptomatic subjects undergoing a routine health check-up were evaluated by colonoscopy. The colorectal polyps were assessed, and medical history and demographic data were obtained from each patient...

PURPOSE To evaluate the accuracy of sonographic endometrial thickness and hysteroscopic characteristics in predicting malignancy in postmenopausal women undergoing surgical resection of endometrial polyps. METHODS Five hundred twenty-one (521) postmenopausal women undergoing hysteroscopic resection of endometrial polyps between January 1998 and December 2008 were studied. For each value of so...

BACKGROUND Although colonoscopy is the criterion standard for detecting colorectal adenomas and cancers, a significant percentage of adenomas are missed. OBJECTIVE To compare forward-viewing with ultrawide-viewing colonoscopy in the detection of simulated colon polyps in an in vitro colon model. DESIGN Prospective, multicenter. SETTING Six endoscopy units (3 in the United States and 3 in ...
