Fecal impaction; Plain abdominal X-ray showing a large fecal impaction extending from the pelvis upwards to the left subphrenic space and from the left towards the right flank, measuring over 40 cm in length and 33 cm in width. Specialty: Gastroenterology
While x-ray is a fast and inexpensive to screen for perforation, an abdominal CT scan with contrast is more sensitive and specific for establishing a diagnosis as well as determining the underlying cause. [19] Both CT and x-ray may initially appear normal, in which case diagnosis can be made by open or laparoscopic exploration of the abdomen.
In children, abdominal x-ray is indicated in the acute setting: 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]
It is a hardening of feces into lumps of varying size and may occur anywhere in the intestinal tract but is typically found in the colon. It is also called appendicolith when it occurs in the appendix and is sometimes concurrent with appendicitis. [1] They can also obstruct diverticula. It can form secondary to fecal impaction.
Fecal impaction can occur as well, says Khan, “which is when stool stays in the rectum for so long that it becomes dry and cannot be expelled naturally, so it must be removed with [a health care ...
Plain X-rays are insufficient to diagnose diverticular disease. There is no blood test for diverticulosis. It is important to note that both barium enema and colonoscopy are contraindicated during acute episodes of diverticulitis, as the barium may leak out into the abdominal cavity, and colonoscopy can cause perforations of the bowel wall.
Anisakiasis is demonstrated by Barium X-rays as bowel wall oedema, thickening, ulceration, or stricture due to inflammation. Sometimes worms are seen as long, thread-like, linear filling defects up to 30 cm long. [33] In Typhlitis Barium studies show oedema, ulceration, and inflammation of bowel wall resulting in wall thickening. [33]
Radiographs (X-ray pictures) are taken while barium sulfate, a radiocontrast agent, fills the colon via an enema through the rectum. The term barium enema usually refers to a lower gastrointestinal series, although enteroclysis (an upper gastrointestinal series ) is often called a small bowel barium enema.
