title: Comparison of Laparoscopic and Open Cystopexy in a Cadaveric Canine Model.
abstract: OBJECTIVE
  To describe a technique for laparoscopic cystopexy using knotless barbed suture and to compare this technique with traditional cystopexy using standard suture in a cadaveric canine model.
  
  
  METHODS
  Cadaveric study.
  
  
  METHODS
  Male canine cadavers (n = 12).
  
  
  METHODS
  Cadavers were randomly assigned to 2 groups: laparoscopic (n = 6) and open (n = 6) cystopexy. Laparoscopic cystopexy was performed intracorporeally using barbed, glycomer 631 suture. Open cystopexy was performed using standard glycomer 631 suture. Pre- and postoperative positive contrast cystography was performed in all dogs. Cystopexy procedure time, length and adherence, as well as number of bladder mucosal suture penetrations were compared between groups.
  
  
  RESULTS
  Mean ± SD cystopexy procedure time was 14.0 ± 3.0 minutes and 5.2 ± 0.5 minutes for the laparoscopic and open groups, respectively (P = .0007). Laparoscopic and open cystopexy lengths were 2.5 ± 0.4 and 2.4 ± 0.5 cm, respectively (P = .43). Partial suture pullout occurred in 1 dog in the laparoscopic group but subjective cystopexy adherence was adequate in all dogs. Bladder mucosal suture penetration occurred in 3 dogs in both groups (P = .86). Two of 6 cadavers with luminal suture penetration had minor contrast leakage on postoperative contrast cystography. Pre- and postoperative contrast cystography revealed appropriate bladder position in all cadavers.
  
  
  CONCLUSIONS
  Laparoscopic cystopexy using knotless suture was comparable to an open cystopexy but was associated with a slightly longer procedure time and should be suitable for laparoscopic cystopexy in vivo.
