What is the surgery for SMA syndrome?
Options for surgery include a duodenojejunostomy or gastrojejunostomy to bypass the obstruction or a duodenal derotation procedure (otherwise known as the Strong procedure) to alter the aortomesenteric angle and place the third and fourth portions of the duodenum to the right of the superior mesenteric artery.
How do you test for SMA syndrome?
The diagnosis is often made after other causes of symptoms have been ruled out. Tests that may be needed to evaluate a person with symptoms of SMAS include abdominal X-rays , upper GI series, ultrasound , arteriography, and computed tomography (CT scan).
What is Strong’s procedure?

What is SMA on CT scan?
An abdominal computed tomography (CT) scan with contrast revealed the narrowing of the third portion of the duodenum compressed by the superior mesenteric artery (SMA), with dilation of the portion of the duodenum proximal to the compression.
How long does it take to recover from SMA syndrome?
More than 70% of patients have improvement of symptoms after 6 weeks of treatment. On rare occasions, surgery may be needed to correct the obstruction and can now be done laparoscopically or even robotically.
What organs does the SMA feed?
The superior mesenteric artery provides blood to the pancreas and parts of the small intestine and large intestine.
Is SMA syndrome curable?
What are the possible outcomes of Superior Mesenteric Artery Syndrome? SMAS is a medically treatable cause of small bowel obstruction with an overall good prognosis.
