The key radiographic signs that allow distinction between a high-grade SBO and a low-grade obstruction are the presence of small bowel distention,
with maximal dilated loops averaging 36 mm in diameter and exceeding 50% of the caliber of the largest visible colon loop as well as a 2.5 times increase in the number of
…
Which of the following radiographic findings is indicative of small bowel obstruction?
Signs of small-bowel obstruction on radiographs include
distended loops of bowel greater than 3 cm, collapsed colon, differential air-fluid levels
, and thickened bowel wall (Figs. 1A and 1B). The string-of-pearls sign may also be identified (Figs.
What are the symptoms of radiographic bowel obstruction?
Findings on an X-ray suggestive of bowel obstruction include
dilated bowel loops with air-fluid level, distal collapsed bowel, absence of gas in the abdomen
or alternatively, “string of pearls” sign indicating trapped flatus.
What are the differential diagnosis for intestinal obstruction?
Conditions that should be considered when evaluating a patient with large-bowel obstruction (LBO) include
constipation, cecal or sigmoid volvulus, intussusception
, intestinal perforation, acute colonic pseudo-obstruction (ACPO; Ogilvie syndrome), mesenteric and mesenteric artery ischemia.
What is the best imaging for bowel obstruction?
CT Findings
.
Multidetector CT
is the single best imaging tool for suspected SBO. Multidetector CT has a sensitivity and specificity of 95% for the diagnosis of high-grade SBO and is less accurate in partial obstruction (4,6–8).
What is the difference between small and large bowel obstruction?
In small bowel obstruction, the pain tends to be
colicky
(cramping and intermittent) in nature, with spasms lasting a few minutes. The pain tends to be central and mid-abdominal. Vomiting may occur before constipation. In large bowel obstruction, the pain is felt lower in the abdomen and the spasms last longer.
What is the leading cause of small bowel obstruction?
Conclusion: The most common cause of SBO is
adhesions
followed by Crohn’s disease and neoplasia.
What are the mechanical causes of intestinal obstruction?
- Adhesions or scar tissue that forms after surgery.
- Foreign bodies (objects that are swallowed and block the intestines)
- Gallstones (rare)
- Hernias.
- Impacted stool.
- Intussusception (telescoping of one segment of bowel into another)
- Tumors blocking the intestines.
Can bowel obstruction be seen on ultrasound?
These images are more detailed than a standard X-ray, and are more likely to show an intestinal obstruction. Ultrasound. When an intestinal obstruction occurs in children, ultrasound is often the preferred type of imaging.
Do Xrays show intestinal blockage?
An abdominal X-ray, which can
find blockages in the small and large intestines
. A CT scan of the belly, which helps your doctor see whether the blockage is partial or complete.
What is the management of intestinal obstruction?
Management of uncomplicated obstructions includes
fluid resuscitation with correction of metabolic derangements, intestinal decompression, and bowel rest
. Evidence of vascular compromise or perforation, or failure to resolve with adequate bowel decompression is an indication for surgical intervention.
What are the complication of intestinal obstruction?
Intestinal obstruction can cut off the blood supply to part of your intestine.
Lack of blood causes the intestinal wall to die
. Tissue death can result in a tear (perforation) in the intestinal wall, which can lead to infection. Infection.
Is an ileus the same as a bowel obstruction?
Ileus defined as
nonmechanical obstruction of bowel usually secondary to inhibition of peristalsis
. Small bowel obstruction defined as mechanical obstruction of small bowel due to adhesions, mass, volvulus or other internal or external compression.
Does Coke help with bowel obstruction?
Researchers at the medical school of Athens University found that of the 46 patients who were given Coca-Cola to
treat the blockage
, the treatment cleared the blockage in half, 19 patients needed additional non-invasive treatment, and four needed full surgery.
