We report a case of a benign fibroepithelial polyp of the lowermost ureter, which prolapsed into the bladder and was associated with a huge, impacted ureteral stone. The polyp was considered to have resulted from chronic irritation of the ureteral mucosa caused by the stone. Review of the literature showed that six out of 74 reported cases had concomitant stones but the polyp was apparently cau...

BACKGROUND Combined endoscopic laparoscopic surgical removal is used for polyps in the colon that are not suitable for endoscopic removal because of size, location, or scarring. However, the placement of a linear stapler can be challenging. Currently a wedge resection is mostly documented in the cecum or ascending colon. OBJECTIVE We report on our experience with limited endoscopy-assisted we...

Computational intelligent systems could reduce polyp miss rate in colonoscopy for colon cancer diagnosis and, thus, increase the efficiency of the procedure. One of the main problems of existing polyp localization methods is a lack of spatio-temporal stability in their response. We propose to explore the response of a given polyp localization across temporal windows in order to select those ima...

In this paper, we first introduce three different geometric features including shape index, curvedness and sphericity ratio, for colonic polyp detection. A new color coding scheme is designed to highlight the detected polyps, and help radiologists to distinguish them from other tissues more easily. The key idea is to place the detected polyp candidates at the same locations in a newly created p...

Ganglioneuroma (GN) of the gastroin-testinal (GI) tract is rare tumor composed of ganglion cells, nerve fibers, and supporting cells of the enteric nervous system. Diffuse ganglioneuromatosis is associated with multiple endocrine neoplasia IIB (MEN IIB), neurofibro-matosis type I (NF1, also known as von Recklinghausen disease), multiple cu-taneous or GI tract neurofibromatosis, and neurogenic s...

OBJECTIVE The purposes of this study were to directly compare 3D endoluminal volume rendering and navigational capabilities of three different CT colonography systems and to assess feasibility of 3D evaluation for primary polyp detection. MATERIALS AND METHODS Closely matched endoluminal images from three CT colonography software systems (Navigator, Vitrea 2, and V3D-Colon) and optical colono...

Hairy polyp is a rare, benign tumor that comprises ectodermal and mesodermal germ layers. The embryogenesis of hairy polyp is precisely unknown, and concurrently, it has a female predominance. Although hairy polyp is observed in every part of the body; it is frequently located in the nasopharynx and oropharynx. Respiratory distress and feeding difficulties are the most related symptoms. Differe...

Sushruta has mentioned 31 Rogas of Nasa in which Nasarsha is described. can be correlated to Nasal polyp. It a benign mass inflamed mucosal tissue wall. Some common symptoms polyp congestion, sneezing, headache and runny nose. The prevalence rate polyps approximately 1% 4% general population. Certain medications surgeries are used treat Polyp modern science with major reccurence rate. In Ayurve...

Fermentation of carbohydrates in the colon can stimulate cell proliferation and could thus be a cancer risk. The effects of resistant carbohydrates, i.e. those not digested and absorbed in the small intestine, on cell proliferation, crypt fission and polyp development were investigated in wild-type and adenomatous polyposis coli multiple intestinal neoplasia (Apc(Min/+)) mice. Fifteen 4-week-ol...

Abstract Aims The Joint Advisory Group on GI Endoscopy (JAG) has set key quality indicators for colonoscopy, which includes an adenoma detection rate of a minimum 15%. Given the difficulty in reporting rate, JAG have stated that polyp is accepted as surrogate measure. Our aim was to assess whether can be used substitute marker detection, by examining histology samples taken polyps determine wha...
