......................................... Received: 03-10-12 Accepted: 17-01-13 Abstract Colonic polypectomy is the most important tool for stopping adenoma-cancer, and the inject and cut technique has demonstrated efficacy and safety in studies conducted in other countries. Since in our country there are no reported data on performance of this technique, it is necessary to describe the experie...

BACKGROUND Few studies have reported the expression of Hepatocyte Paraffin 1 (Hep Par 1) in colorectal carcinomas with contradictory results. Reported rate of expression ranged from 4-50%. Moreover, the correlation between Hep Par 1 expression and clinicopathological parameters has not been investigated. The objective of the present study was to investigate the role of CPS1 (using Hep Par 1) in...

A review of the pathophysiology, clinical presentation, and diagnosis of colon cancer and colonic polyps is important and timely. This field is rapidly changing because of breakthroughs in the molecular basis of carcinogenesis and in the technology for colon cancer detection and treatment. This article reviews colon cancer and colonic polyps, with a focus on recent dramatic advances, to help th...

Background and study aims Colonic polyps > 1 cm in size are commonly managed using hot polypectomy techniques. The most frequent adverse events (delayed bleeding, post-polypectomy syndrome, and perforation) are related to electrocautery-induced injury. We hypothesized that cold resection of large polyps may have similar efficacy and improved safety compared to hot polypectomy. Our aims were to ...

The gastric polyps are rare as compared to the colonic polyps. Multiple gastric polyps are seen in association with other polyposis syndromes like juvenile polyposis, Gardner's syndrome, the Peutz-Jeghers syndrome and the Cronkhite-Canada syndrome. Diffuse gastric polyposis is a rare entity and only few cases have been reported. The mode of treatment is surgery, either total or near total gastr...

Colon cancer is one of the leading causes of cancer deaths in the United States. However, most colon cancers can be prevented if precursor colonic polyps are detected and removed. An advanced computer-aided diagnosis (CAD) scheme was developed for the automated detection of polyps at computed tomographic (CT) colonography. A region encompassing the colonic wall is extracted from an isotropic vo...

PURPOSE Arachidonic acid metabolism via the cyclooxygenase (COX) and 5-lipoxygenase (5-LOX) pathways modulates cell growth and apoptosis. Many studies have examined the effects of COX inhibitors on human colorectal cancer, but the role of 5-LOX in colonic cancer development has not been well studied. The purpose of this study was to evaluate the expression of 5-LOX in colonic polyps and cancer ...

conclusion we constructed and validated a ct colonography phantom with correct density allowing performance of reproducible experiments. materials and methods we found 15 different phantom designs by literature search and compared their advantages and disadvantages based on their description and images. we tested various materials for density and mechanical properties and constructed a phantom ...

Background In young patients, multiple osteomas in the jaw and sebaceous cysts are signs which usually precede the diagnosis of Gardner’s syndrome. It is the association of multiple colonic polyps (familial adenomatosis polyposis coli) and extracolonic findings. By the fourth decade of life the colonic polyps undergo malignant transformation. Case reports The oral manifestations are described i...
