title: [Gastrostomy in dogs with magnetic compression technique combined with endoscopy].
abstract: OBJECTIVE
  To evaluate the feasibility of endoscopic gastrostomy combined with magnetic compression techniques in dogs.
  
  
  METHODS
  The magnetic compression device consisted of a couple of cylindrical magnets with a hole in the center. A 14-French gastric tube was inserted through the hole and fixed on the parent magnets. Four male mongrel dogs were selected randomly for the operation. The daughter magnet was placed into the dog's gastric body by a Zebra Guidewire under endoscopy, then a skin incision was performed on the left upper abdomen, through which the subcutaneous tissues and muscle were isolated up to the peritoneum. The parent magnet was placed on the surface of the peritoneum, which attracted the daughter magnet inside the gastric cavity automatically to compress the gastric wall and peritoneum. A needle was inserted through the gastric tube and punctured the tissue in the hole of the magnets repeatedly to form a fistula. After removing the needle, the gastrostomy was complete. The fistula was observed and its specimen was taken two weeks later under laparotomy.
  
  
  RESULTS
  All the four operations were successfully performed, and the operation time was 11-15 minutes. The stoma was matured immediately, through which early enteral nutrition support was administered. The gastric wall and peritoneum were observed with well healing and no adhesion in the abdominal cavity under laparotomy two weeks after the operation.
  
  
  CONCLUSIONS
  The gastrostomy performed by magnetic compression technique combined with endoscopy is convenient, minimally invasive and safe, which may be used in future clinical practice.
