Randomized Controlled Trial Multicenter Study Comparative Study
Endovascular versus open repair of abdominal aortic aneurysm.
Few data are available on the long-term outcome of endovascular repair of abdominal aortic aneurysm as compared with open repair. ⋯ In this large, randomized trial, endovascular repair of abdominal aortic aneurysm was associated with a significantly lower operative mortality than open surgical repair. However, no differences were seen in total mortality or aneurysm-related mortality in the long term. Endovascular repair was associated with increased rates of graft-related complications and reinterventions and was more costly. (Current Controlled Trials number, ISRCTN55703451.)

Although rates of detection of adenomatous lesions (tumors or polyps) and cecal intubation are recommended for use as quality indicators for screening colonoscopy, these measurements have not been validated, and their importance remains uncertain. ⋯ The adenoma detection rate is an independent predictor of the risk of interval colorectal cancer after screening colonoscopy.
