We have developed a method for the routine primary culture of human colonic epithelial cells. Cultured cells exhibited characteristic epithelial structures, including a brush border and junctional complexes. Flask-like goblet cells containing mucus were also seen within the epithelial monolayer. [3H]Thymidine labeling indices were used to distinguish between cultured cells from familial polypos...
In this paper, we present a computer-aided detection (CAD) method to extract and use internal features to reduce false positive (FP) rate generated by surface-based measures on the inner colon wall in computed tomographic (CT) colonography. Firstly, a new shape description global curvature, which can provide an overall shape description of the colon wall, is introduced to improve the detection ...
OBJECTIVES Obesity is associated with the activation of the molecular pathways that increase the risk of colorectal cancer. Increasing body mass index may accelerate the development of adenomatous polyps, the antecedent lesion of colorectal cancer. The aim of this study was to assess the BMI effect on the risk of colonic polyp and adenoma in African-American. METHODS The records of 923 patien...
colon polyps are less than 1 cm in size. However, en-doscopists often encounter large sessile colon polyps greater than 2 cm in practice. Removal of a large sessile colon polyp is difficult due to a high rate of procedure-related complications , such as bleeding and perforation. Therefore, patients with large sessile colon polyps are referred to a tertiary hospital for appropriate treatment. Th...
Ureteral fibroepithelial polyps are rarely seen benign tumors with mesodermal origin. These polyps can involve kidney, pelvis, ureter, bladder, and urethra. The most common symptoms are hematuria and flank pain. The choice of treatment is either endoscopic or surgical resection of polyp by sparing kidney. Here, we presented a pediatric case with giant, fibroepithelial polyp that mimics bladder ...
Inflammatory fibroid polyps are uncommon benign lesions that originate in the submucosa of the gastrointestinal tract. The stomach and the ileum are the most commonly affected sites. Although inflammatory fibroid polyp is one of the rare conditions leading to intestinal obstruction in adults, it should be considered as a possible diagnosis in obstructive tumors of the small bowel causing intuss...
A fibroepithelial polyp of the bronchus is a rare, benign, and endobronchial tumor, histologically consisting of fibrovascular stroma covered by normal respiratory epithelium. We report a case of a fibroepithelial polyp arising from the left main bronchus. On CT, a characteristic lobulating contour of the endobronchial nodule was well visualized, which histopathologically represented a typical ...
