The small bowel feces sign results from stagnation of enteric contents within dilated segments of the small intestine. [1] When intestinal motility is impaired due to obstruction, progressive dehydration of luminal contents occurs, leading to the formation of solid particulate matter that mimics feces. [ 3 ]
Symptoms of AVMs vary according to their location. Most neurological AVMs produce few to no symptoms.Often the malformation is discovered as part of an autopsy or during treatment of an unrelated disorder (an "incidental finding"); in rare cases, its expansion or a micro-bleed from an AVM in the brain can cause epilepsy, neurological deficit, or pain.
An unusually narrow, stalk-like mesentery The position of the intestines, narrow mesentery and Ladd's bands can contribute to several severe gastrointestinal conditions. The narrow mesentery predisposes some cases of malrotation to midgut volvulus, a twisting of the entire small bowel that can obstruct the mesenteric blood vessels leading to ...
Should the diagnosis be in doubt, a barium enema may be used to demonstrate a "bird's beak" at the point where the segment of proximal bowel and distal bowel rotate to form the volvulus. [citation needed] This area shows an acute and sharp tapering and looks like a bird's beak.
In medicine (gastroenterology), angiodysplasia is a small vascular malformation of the gut. It is a common cause of otherwise unexplained gastrointestinal bleeding and anemia. Lesions are often multiple, and frequently involve the cecum or ascending colon, although they can occur at other places.
The distension is more generalised the further down the bowel the atresia is located and is thus most prominent with ileal atresia. [1] [2] Inability to pass stool is most common with duodenal or jejunal atresia; [2] if stool is passed, it may be small, mucus-like and grey. [1] Occasionally, there may be jaundice, which is most common in ...
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 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 ...
