Need for supine and prone imaging. Axial CT image in the supine position (A) shows round filling defect (arrow) in the dorsal aspect of the transverse colon. Axial CT image in the same patient in the prone position (B) shows the filling defect is now along...
one-half (50 ml) of the solution was deposited in the region of the cecum/proximal ascending colon and the other half was drizzled throughout the transverse colon as the colonoscope was withdrawn. Both patients
Biopsies were obtained at the time of colonoscopy from the rectum, hepatic flexure, transverse colon, sigmoid colon and anal verge, as a part of their routine colonoscopy. The biopsies were then evaluated for the presence of CRC and grading was carried out according to TNM staging classification...
Thus, bleeding from the anus, rectum, and sigmoid colon tends to be bright red, whereas bleeding from the transverse colon and the right colon tends to be dark red or maroon-colored. With bleeding from the upper GI tract and depending on how long the blood remains in the stomach and ...
water is absorbed to transform the liquid chyme into a solid stool. This happens as it passes through the different parts of the colon, from a liquid form in the ascending colon, to a mush in the transverse colon and finally a firm but soft stool in the descending colon. This reabsorption...
s of water and electrolytes are absorbed. Despite this, water makes up about 70% of the fecal weight. Water absorption transforms the fluid chyme into a mush-like consistency by the time it passes through the transverse colon. It solidifies further along its passage down the descending colon...
Ischemia of the bowel occurs when blood flow to the bowel reduces or stops. For example,ischemic colitisusually occurs at the junction of the transverse and descending colonand can produce bright red or maroon blood. Rectal Bleeding, Anorectal Disorders ...
(defecate) under deliberate control. In these patients, the volume of fluid irrigated into the rectum or colon via the anus has the effect of stimulating intestinal peristalsis, with the objective of emptying the large intestine as completely as possible. The result, for the patient, is a ...
