Stainless Steel Wire Suture Technique in Thoracic Surgery

Before embarking upon any new surgical procedure or technique three condi- tions need to be fulfilled. First, it must be shown to be necessary, secondly, there must be sufficient experimental evidence to justify a trial of the new method; and tlhirdly, any advantage the new may appear to have over the old must be shown to possess statistical significance before its final adoption is justified, unless there are overwhelming practical advantages such as greater simplicity or economy. If thiese three rules are observed there will be far less of the fashionable " try every- thing once " approach that is responsible for so much confusion and wasted effort.
