How can you tell the difference between a 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 objective signs would be seen in a patient with a small bowel obstruction?
Presentation. The patient with a small bowel obstruction will usually present with abdominal pain, abdominal distension, vomiting, and inability to pass flatus. In a proximal obstruction, nausea and vomiting are more prevalent. Pain is frequently described as crampy and intermittent with a simple obstruction.
How do you assess a bowel obstruction?
To confirm a diagnosis of intestinal obstruction, your doctor may recommend an abdominal X-ray. However, some intestinal obstructions can’t be seen using standard X-rays. Computerized tomography (CT). A CT scan combines a series of X-ray images taken from different angles to produce cross-sectional images.
What does SBO look like on CT?
What is the most common cause of small bowel obstruction?
CT criteria for SBO are the presence of dilated small bowel loops (diameter >2.5 cm from outer wall to outer wall) proximally to normal-caliber or collapsed loops distally (,Fig 4) (,16).
Can a CT scan detect bowel obstruction?
Small–bowel obstruction (SBO) is caused by a variety of pathologic processes. The most common cause of SBO in developed countries is intra-abdominal adhesions, accounting for approximately 65% to 75% of cases, followed by hernias, Crohn disease, malignancy, and volvulus.

Can a bowel obstruction be seen on ultrasound?
Bowel obstruction is considered to be present at CT when distended bowel loops are seen proximal to collapsed loops. When a point of transition from dilated small bowel to normal-caliber bowel without apparent cause is identified, adhesions are the presumed cause (,Figs 1, ,2).
Is an ileus the same as a bowel obstruction?
Readily accessible in the ED, abdominal ultrasound can facilitate diagnosis of small bowel obstruction. An imaging modality readily available in the ED, bedside ultrasound can assist in quickly diagnosing this condition.
What do they do for a bowel obstruction?
Ileus versus intestinal obstruction
An ileus and an intestinal obstruction have similarities, but an ileus results from muscle or nerve problems that stop peristalsis while an obstruction is a physical blockage in the digestive tract.
How long can you live with a bowel obstruction?
Most bowel obstructions are partial blockages that get better on their own. The NG tube may help the bowel become unblocked when fluids and gas are removed. Some people may need more treatment. These treatments include using liquids or air (enemas) or small mesh tubes (stents) to open up the blockage.
Can small bowel obstructions come and go?
Without any fluids (either as sips, ice chips or intravenously) people with a complete bowel obstruction most often survive a week or two. Sometimes it’s only a few days, sometimes as long as three weeks. With fluids, survival time may be extended by a few weeks or even a month or two.
