To fill this knowledge gap, Dr. Lukens and colleagues looked at the diagnostic yield and complication rates in 62 patients with surgically altered bowel anatomy who underwent DBE at Mayo Clinic in Florida between 2006 and 2011: 1  Eleven of the procedures were DBE-ERCPs.
The lateral masses are paired blocks of bone located lateral to the sacral foramina. The sacral ala is the wing-shaped bone found lateral to the S1 vertebral body. Histologic study of the sacral alae demonstrates decreased trabecular density (âalar voidsâ) within each of these structures (3).
Aortic regurgitation (AR) is the diastolic flow of blood from the aorta into the left ventricle (LV). Regurgitation is due to incompetence of the aortic valve or any disturbance of the valvular apparatus (eg, leaflets, annulus of the aorta) resulting in the diastolic flow of blood into the left ventricular chamber. Abnormalities of the ascending aorta, in the absence of valve pathology, may also cause AR.
