Incision choice in laparatomy: a comparison of two incision techniques in ovariectomy of rats

The choice of surgical incision in the abdomen is determined by access for surgery. It has been suggested that utilizing a transverse or oblique rather than a midline incision may influence other parameters such as duration of surgery, recovery and complication rates. However, there is a little study as to whether a particular incision confers any advantage. The aim of the study was to determine whether a dorso-lateral incision or a transverse incision confers any advantage to the rats. Ninety five 16 weeks age female Sprague-Dawley rats were divided into two groups. Ovariectomy was preceded either by a single dorso-lateral incision (in the first group, n=45) or a single transverse lateral incision (in the second group, n=50). Animals in group A (vertical incision, n= 45) had a mean weight of 259.11±20.31 and those in group B (transverse incision, n=50) weighted 254.20±20.31 g, There was significant differences in the duration of surgery in the two groups (p
