The stepladder sign is a radiological finding observed in the context of small bowel obstruction on abdominal X-rays or computed tomography scans. It refers to the appearance of multiple, dilated small bowel loops arranged in a step-like configuration, typically visible in upright or lateral decubitus imaging positions.
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 small bowel feces sign is a radiological finding observed in radiological imaging studies, particularly in cases of small bowel obstruction. [1] It is characterized by the presence of particulate matter resembling fecal material within the lumen of dilated small bowel loops.
A sentinel loop is a sign seen on a radiograph that indicates localized ileus from nearby inflammation. [1] Simply put, it is the dilation of a segment of small intestine to be differentiated from colonic cutoff sign which is a dilation of a segment of large bowel. [citation needed]
Volvulus causes severe pain and progressive injury to the intestinal wall, with accumulation of gas and fluid in the portion of the bowel obstructed. [11] Ultimately, this can result in necrosis of the affected intestinal wall, acidosis, and death. This is known as a closed-loop obstruction because there exists an isolated ("closed") loop of bowel.
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]
Chilaiditi syndrome is a rare condition when pain occurs due to transposition of a loop of large intestine (usually transverse colon) in between the diaphragm and the liver, visible on plain abdominal X-ray or chest X-ray. [1] Normally this causes no symptoms, and this is called Chilaiditi's sign. The sign can be permanently present, or ...
Simple and cheap to perform, plain film x-rays can show the traditional indicator of air-fluid levels and dilated bowel loops, which is best seen in the erect film. [25] Abdominal x-rays , however, are unable to definitively differentiate between genuine mechanical intestinal obstruction and pseudo-obstruction . [ 26 ]
