Background
There has been increasing interest in audit of outcome following surgery. A previous study reported a significant difference in clinical outcome between consultant and trainees but there is no information on technical factors. Duplex ultrasonography before wound closure was used to compare clinical and technical outcome for consultant and trainees.
Method
Patients underwent endarterectomy (89 by consultant, 60 by six trainees). In the consultant group nine vessels were patched and 36 patients underwent shunting compared with seven and 31 respectively for trainees.
Results
In the consultant group there were two deaths, one stroke, one transient ischaemic attack (TIA) and two cranial nerve injuries. The neurological event rate was 2 per cent, and overall stroke and death rate 3 per cent. There were ten residual flaps (11 per cent) (three re‐explored) and eight kinks (9 per cent). The residual stenosis rate was 10 per cent (nine of 89) and following re‐exploration this reduced to 7 per cent. In the trainee group there was one death, two strokes, one TIA and one cranial nerve injury. The neurological event rate was 5 per cent, and the overall stroke and death rate 3 per cent. There were nine flaps (15 per cent) (four re‐explored) and 13 kinks (22 per cent). The residual stenosis rate was 22 per cent (13 of 60) which reduced to 15 per cent (nine of 60) following re‐exploration. There was no significant difference in clinical outcome between consultant and trainees but there was an increased incidence of technical problems among the trainees (t = 2·12, P < 0·05).
Conclusion
Intraoperative duplex ultrasonography is a valuable method for assessing surgical technique; it gives immediate feedback to the surgeon, enables corrective measures to be taken and may facilitate training. © 1999 British Journal of Surgery Society Ltd
