[Graduated ruler for making a transverse suprapubic incision]

The transverse suprapubic incision is the most usual approach to laparotomy in obstetrics and gynaecology. It has many advantages both from the aesthetic as well as the functional points of view. The low transverse scar is hidden in the region of the pubis. Post-operative breakdowns (such as hernia and eventertion) that occur with longitudinal incisions have almost disappeared. The site, the length and the height of the incision vary according to the surgeon's ideas and his experience. The result cosmetically therefore varies and the optimum benefit is not always achieved. We describe a graduated ruler specially designed for the transverse suprapubic incision. It was worked out in 1984. It makes it easier to standardise the technique of suprapubic incision, but one that can be changed according to variations in body contours. The ruler can be sterilised. It is available in two models: one, a flexible one which is ideal for caesarean sections and laparotomies in fat women or where the abdominal wall is distorted by tumours under it; the second model is rigid and should be able to be used on the normal flat abdomen. One and a half years experience shows that the ruler can be used to standardise the technique of transverse suprapubic incision. It also helps to teach this method of laparotomy; and the cosmetic results have become better.
