title: Laparoscopic-assisted colopexy and sterilization in male dogs: short-term results and physiologic consequences.
abstract: OBJECTIVE
  To describe laparoscopic-assisted colopexy and sterilization, and evaluate outcome and effects in healthy male dogs.
  
  
  METHODS
  Experimental study.
  
  
  METHODS
  Male Beagle dogs (n=7).
  
  
  METHODS
  A laparoscopic-assisted, extracorporeally sutured colopexy, and sterilization by ligation and section of the testicular vessels and ductus deferens were evaluated 11 weeks after surgery. Ex vivo tensile tests were performed on the colopexy sites and loss of testicular function was assessed by monitoring serum testosterone, and by ultrasonographic and histologic examinations of the testes. Systemic inflammation and potential iatrogenic colonic functional disorders were investigated by monitoring serum C-reactive protein (CRP) in the perioperative period and from a sulfapyridine (SP) kinetic profile obtained before and 10 weeks after surgery.
  
  
  RESULTS
  No intraoperative complications were recorded and clinical outcome was considered fair in all dogs. A mean tensile force of 42 N was required to disrupt colopexies. No relevant postoperative increase in CRP concentrations or changes in SP kinetics were observed. Testicular function was lost.
  
  
  CONCLUSIONS
  Laparoscopic-assisted colopexy achieved adhesion of the colon to the abdominal wall and testicular endocrine function and spermatogenesis were eliminated by laparoscopic castration.
