External-to-internal iliac stent-graft: medium-term patency following exclusion of a retrogradely perfused common iliac aneurysm.

Following complicated aortic aneurysm surgery a complete left iliac occlusion resulted in buttock claudication. A retrogradely perfused right common iliac aneurysm expanded. Exclusion was by external-to-internal iliac stent-graft.

Contribution of posture to anorectal manometric measurements: are the measurements in left-lateral position physiologic?

Purpose: Anorectal manometry is commonly used to investigate fecal incontinence. Traditional practice dictates that measurements are performed with the patient in the left-lateral position however, episodes of fecal incontinence usually occur in the erect position. The influence of erect posture on anorectal manometry has not been studied.
