Abstract: | Opinion statement Superior mesenteric artery (SMA) syndrome (also known as Wilkie’s syndrome, chronic duodenal ileus, or cast syndrome) occurs
when the third portion of the duodenum is compressed between the SMA and the aorta. The major risk factors for development
of SMA syndrome are rapid weight loss and surgical correction of spinal deformities. The clinical presentation of SMA syndrome
is variable and nonspecific, including nausea, vomiting, abdominal pain, and weight loss. The diagnosis is based on radiographic
findings of duodenal compression by the SMA. The treatment of SMA syndrome is aimed at the precipitating factor, which usually
is related to weight loss. Therefore, conservative therapy with nutritional supplementation is the initial approach, and surgery
is reserved for those who do not respond to hyperalimentation. |
