title: A new anatomical and surgical landmark in internal abdominal oblique muscle: fat triangle.
abstract: OBJECTIVE
  To determine the anatomical landmark within the internal oblique muscle.
  
  
  METHODS
  In a prospective study, the abdominal wall was examined for internal oblique muscle land marks in 900 patients undergoing laparatomy.
  
  
  RESULTS
  There was a fat line at anterior superior iliac spine level to access the underlying layers and then to the abdominal cavity.
  
  
  CONCLUSIONS
  A fat triangle within the internal oblique muscle provides a suitable region of surgical incision at the lower part of the abdominal wall.
