title: [Hernial sac hystology of the inguinal hernias: identification of smooth muscle fibers and their relation with the blood vessel].
abstract: OBJECTIVE
  To study the correlation between the blood vessels and the smooth muscles in the hernial sac.
  
  
  METHODS
  250 surgeries were done to correct inguinal hernias, in children and adults from two months to 75 years old, from March 2002 and February 2003. A hundred ninety two hernial sacs were isolated in 184 surgeries and only eight patients were treated of bilateral inguinal hernia. They were excluded the patients with inguinal hernia which did not have hernial sac during the surgeries and the adult women cause there was no material. From these 184 cases, 90 patients were chosen aleatorialy to make this analysis. They were distributed as follows: 30 male children, 30 female children and 30 male adults.
  
  
  RESULTS
  The vessels were present in all groups with a media of 11 vessels per field. The smooth muscle fibers were present in some cases and the horizontal distance was in media 0,1665micro and the vertical 0,1378micro in the adult group with a media of 4,5 isle of smooth muscle fibers, in the child male group the horizontal distance was 0,135micro, the vertical 0,190micro and the isle, 5,35. In the child female group, the horizontal distance was 0,052micro, the vertical 0,037micro and the median number of isles, 4,75.
  
  
  CONCLUSIONS
  The majority of smooth muscles fibers would be proper of the hernial sac independent of the smooth muscles fibers of the blood vessels.
