            Notes: Case report of an 82-year-old woman diagnosed with SMAS 6 days post-op for colorectal resection due to cancer. Tests revealed that the jejunum passed under the duodenum causing an obstruction in both places. A feeding tube was placed and the patient was released to skilled nursing, where her symptoms gradually improved. Link: http://link.springer.com/article/10.1007%2Fs10140-003-0322-3
