Colorectal Laterally Spreading Tumors by Computed Tomographic Colonography
To date, few reports focused primarily on detecting colorectal laterally spreading tumors (LSTs) have been published. The aim of this study was to determine the visibility of LSTs on computed tomographic colonography (CTC) compared with that on colonoscopy as a standard. We retrospectively reviewed and matched data on endoscopic and CTC reports in 157 patients (161 LSTs) who received a multidet...
متن کاملGene expression profiling of laterally spreading tumors
BACKGROUND Laterally spreading tumors (LSTs) are generally defined as lesions >10 mm in diameter, are characterized by lateral expansion along the luminal wall with a low vertical axis. In contrast to other forms of tumor, LSTs are generally considered to have a superficial growth pattern and the potential for malignancy. We focused on this morphological character of LSTs, and analyzed the gene...
متن کاملMany Options to Manage Laterally Spreading Tumors
(LSTs) are found frequently in the colon but not in other sections of the gastrointestinal tract. These tumors are usually less invasive than protruding or depressed tumors of the same size; thus, we have much freedom in selecting treatment modalities for LSTs. However, a pitfall lurks in the technical difficulties. It is preferable to resect every single tumor in one piece if possible, since e...
متن کاملComputed tomography colonography for colorectal cancer screening.
Colorectal cancer screening has been shown to help prevent cancer-related death. Concerns about suboptimal adherence to conventional colonoscopy has led to the search for alternative screening modalities. Computed tomography colono-graphy (CTC) is a highly sensitive and minimally invasive alternative modality. The American College of Radiology has established a standardized reporting system for...
متن کاملComputed Tomography Colonography Technique: The Role of Intracolonic Gas Volume
Introduction. Poor distention decreases the sensitivity and specificity of CTC. The total volume of gas administered will vary according to many factors. We aim to determine the relationship between the volume of retained gas at the time of image acquisition and colonic distention and specifically the presence of collapsed bowel segments at CTC. Materials and Methods. All patients who underwent...
