Rigidity (involuntary contraction of the abdominal muscles) is the most specific exam finding for diagnosing peritonitis. [14] If focal peritonitis is detected, further work-up should be done. If diffuse peritonitis is detected, then urgent surgical consultation should be obtained, and may warrant surgery without further investigations.
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 ...
The total removal of the colon, called a colectomy or resection of affected parts of the colon may be needed if part of the gut dies (for instance toxic megacolon), or if there is a localized area of dysmotility. Gastric and colonic pacemakers have been tried. These are strips placed along the colon or stomach which create an electric discharge ...
The treatment of intestinal ischemia depends on the cause and can be medical or surgical. However, if bowel has become necrotic, the only treatment is surgical removal of the dead segments of bowel. [34] In non-occlusive disease, where there is no blockage of the arteries supplying the bowel, the treatment is medical rather than surgical ...
The treatment of fecal impaction requires both the remedy of the impaction and treatment to prevent recurrences. Decreased motility of the colon results in dry, hard stools that in the case of fecal impaction become compacted into a large, hard mass of stool that cannot be expelled from the rectum.

Under ordinary conditions, the colon receives between 10% and 35% of the total cardiac output. [ 17 ] [ 18 ] If blood flow to the colon drops by more than about 50%, ischemia will develop. The arteries feeding the colon are very sensitive to vasoconstrictors; presumably this is an evolutionary adaptation to shunt blood away from the bowel and ...
A classic association is Heyde's syndrome (coincidence of aortic valve stenosis and bleeding from angiodysplasia). [4] In this disorder, von Willebrand factor (vWF) is proteolysed due to high shear stress in the highly turbulent blood flow around the aortic valve. vWF is most active in vascular beds with high shear stress, including ...
Argon plasma coagulation administered via probe through the colonoscope at an angiodysplasia in the colon. The patient had multiple colonic angiodysplasiae in the setting of aortic stenosis . Other names
