title: Does a muscle flap accelerate wound healing of gastric wall defects compared with an omental flap?
abstract: BACKGROUND
  Most often used for reconstruction at superficial sites, a muscle flap recently was reported to promote clinical wound healing in a duodenal defect. We therefore examined whether a muscle flap could promote wound healing comparably to an omental flap in rats with gastric wall defects.
  
  
  METHODS
  After perforation of the centre of the anterior gastric wall, rats were divided into 2 groups. In the muscle group, a muscle flap was fixed to the defect; in the omentum group, an omental flap was placed over the defect. We histopathologically compared tissue responses during gastric wall healing.
  
  
  RESULTS
  While stratified villi had completely covered the defect by day 7 in both groups, scar maturation differed. Scar tissue persisted in the muscle group, but was gradually replaced by adipose tissue in the omentum group.
  
  
  CONCLUSIONS
  Both muscle and omental flaps accelerated gastric wall wound healing.
  
  
  CONCLUSIONS
  A muscle flap is an excellent alternative for repair of gastric defects when no omental flap is available.
