The main aim of this study is to distend the proximal bowel through infusion of large amount of barium suspension. Otherwise, the distension of distal small bowel is generally similar with small bowel follow-through. Therefore, there is a need to pass a tube through the nose into the jejunum (nasojejunal tube) to administer large amount of ...
Abdominal ultrasound can be used to diagnose abnormalities in various internal organs, such as the kidneys, [1] liver, gallbladder, pancreas, spleen and abdominal aorta.If Doppler ultrasonography is added, the blood flow inside blood vessels can be evaluated as well (for example, to look for renal artery stenosis).
The small intestine forms loops (B2) and slides back into the abdomen (B3) during resolution of the hernia. Meanwhile, the cecum moves from the left to the right side, which represents the additional 180° counterclockwise rotation of the intestine (C, central view). [4] The exact cause of intestinal malrotation is unknown.
Enteroscopy is the procedure of using an endoscope for the direct visualization of the small bowel. Etymologically, the word could potentially refer to any bowel endoscopy (entero-+ -scopy), but idiomatically it is conventionally restricted to small bowel endoscopy, in distinction from colonoscopy, which is large bowel endoscopy.
The Medical Detection Dogs charity has already trained dogs to detect prostate and bladder cancers, and now it’s training them to sniff out colon cancer from urine samples. It’s hoped that ...
Toxic megacolon is mainly seen in ulcerative colitis and pseudomembranous colitis, two chronic inflammations of the colon (and occasionally, in the other type of inflammatory bowel disease, Crohn's disease). Its mechanism is incompletely understood. It is probably due to excessive production of nitric oxide, at least in ulcerative colitis. The ...
Suspected bowel obstruction or gastrointestinal perforation; Abdominal x-ray will demonstrate most cases of bowel obstruction, by showing dilated bowel loops. [1] Foreign body in the alimentary tract; can be identified if it is radiodense. [1] Suspected abdominal mass [1]
The ileum terminates at the cecocolic junction of the large intestine forming the ileal orifice. In the dog the ileal orifice is located at the level of the first or second lumbar vertebra, in the ox in the level of the fourth lumbar vertebrae, in the sheep and goat at the level of the caudal point of the costal arch.
