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.
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 ...
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 ...
Ultrasound and computed tomography (CT) imaging of the abdomen can confirm the diagnosis by demonstrating dilated loops of intestine with material in the intestinal lumen with bubbles. [1] Air-fluid levels may be seen in those affected by DIOS. [1]
An isolated distended loop of bowel is seen near the site of injured viscus or inflamed organ. This loop is called a "sentinel loop." It arises from the body's efforts to localize traumatic or inflammatory lesions. The local distention of that intestinal loop is due to local paralysis and accumulation of gas in the intestinal loop.
X-ray showing distended stomach and bowel loops. Dilated bowel loops are a characteristic of chronic intestinal pseudo-obstruction. Specialty: Gastroenterology: Symptoms: Abdominal pain, bloating, and distension. [1] Duration: Chronic. [1] Causes: Neurologic, paraneoplastic, autoimmune, metabolic/endocrine, genetic, or infectious diseases. [1 ...
Frontal view of the abdomen with double bubble sign, patient was found to have duodenal atresia. In radiology, the double bubble sign is a feature of pediatric imaging seen on radiographs or prenatal ultrasound in which two air filled bubbles are seen in the abdomen, representing two discontiguous loops of bowel in a proximal, or 'high,' small bowel obstruction.
