Abstract
A prospective study comparing two types of surgical clip, the Proximate II (Ethicon) staple and the Michel clip, was performed on 30 thyroidectomy (horizontal) and 50 carotid endarterectomy (vertical) incisions with reference to their ease of handling, patient comfort, complication rate, cosmetic result and cost. In each patient half of the wound was approximated with one type of clip and half with the other. The Proximate II staple was more comfortable for the patient in the vertical wounds (P less than 0.02), easier to remove as judged by the nurse in both horizontal (P less than 0.001) and vertical (P less than 0.02) wounds, and by the patient in the horizontal wounds (P less than 0.02) only. The incidence of inflammation was significantly higher with the Michel clip (P less than 0.001). In both the horizontal (P less than 0.05) and the vertical (P less than 0.001) wounds, when the scar was assessed at the time of discharge from hospital, the Proximate II staple achieved a significantly better result. However, assessment of the wounds by patient and researcher 6 weeks postoperatively, revealed no significant difference between the wounds with regard to cosmetic outcome. The Proximate II design, however, costs between seven and ten times more than the Michel clip depending on the size of the dispenser used, and since the late cosmetic result offers no advantage over the latter design, we feel these financial variables deserve consideration.
