Stepping-table digital subtraction contrast material-enhanced MR angiography has high accuracy compared with catheter angiography in patients with arterio-occlusive disease of the aorta and outflow vessels. These preliminary study results suggest that this technique may ultimately provide a safe, noninvasive, and cost-effective alternative to catheter angiography.

The proportion of patients who had postoperative stoma-related complications did not improve with time, but the rate of parastomal hernias in both groups and night-time emptying in the ileostomy group was worse with time. Ileostomy patients had a higher incidence of skin excoriation, leakage, soiling, and night-time emptying, and they should receive additional support.

These figures provide an essential benchmark for both audit and patient information. Identifying areas of good practice and those that require improvement will ultimately result in better patient care.
