The gastrointestinal wall is inflamed in a number of conditions. This is called esophagitis , gastritis , duodenitis , ileitis , and colitis depending on the parts affected. It can be due to infections or other conditions, including coeliac disease , and inflammatory bowel disease affects the layers of the gastrointestinal tract in different ways.
Depending on the level of obstruction, bowel obstruction can present with abdominal pain, abdominal distension, and constipation.Bowel obstruction may be complicated by dehydration and electrolyte abnormalities due to vomiting; respiratory compromise from pressure on the diaphragm by a distended abdomen, or aspiration of vomitus; bowel ischemia or perforation from prolonged distension or ...
Dilated bowel loops: Loops proximal to the obstruction exhibit dilation (>2.5-3 cm in diameter). Transition zone: A point where the caliber of the bowel changes from dilated to collapsed, indicating the site of obstruction. Air-fluid levels: Seen in upright or decubitus imaging, reflecting stasis of luminal contents.
Through the abdominal wall, organs inside the pelvis can be seen, such as the urinary bladder or the ovaries and uterus in women. Because water is an excellent conductor for ultrasound waves, visualizing these structures often requires a well-filled urinary bladder (this means the patients has to drink plenty of water before the examination).
Reduced forward movement of bowel contents results in a build up of pressure within the part of the bowel just before the site of obstruction. This increased pressure may prevent blood flow from reaching the bowel wall, resulting in bowel ischemia (lack of blood flow), necrosis, and eventually perforation. [5]
A Meckel's diverticulum, a true congenital diverticulum, is a slight bulge in the small intestine present at birth and a vestigial remnant of the vitelline duct.It is the most common malformation of the gastrointestinal tract and is present in approximately 2% of the population, [1] with males more frequently experiencing symptoms.
Bowel ultrasound (US) is a cost-effective, well-tolerated, non-invasive and readily available tool for the management of patients with inflammatory bowel disease (IBD), including UC, in clinical practice. [79] Some studies demonstrated that bowel ultrasound is an accurate tool for assessing disease activity in people with ulcerative colitis.
A lower gastrointestinal series is a medical procedure used to examine and diagnose problems with the human colon of the large intestine. Radiographs (X-ray pictures) are taken while barium sulfate, a radiocontrast agent, fills the colon via an enema through the rectum.
