title: Efficiency of 4% icodextrin in preventing adhesions to spiral tacks used to fix intraperitoneal prostheses.
abstract: OBJECTIVE
  This study was designed to evaluate the extent of adhesion formation to prostheses fixed with spiral tacks and to establish whether the use of Ringer's lactate or icodextrin could prevent these adhesions.
  
  
  METHODS
  24 New Zealand white rabbits weighing around 3,000 g were implanted with a 7 x 5 cm patch of ePTFE (DualMesh) through a midline laparotomy. The prosthesis was fixed to the intact peritoneum using spiral tacks. Three study groups were established according to whether the animals were: implanted with ePTFE fixed with spiral tacks or implanted with ePTFE fixed with spiral tacks and simultaneously administered Ringer's lactate or 4% icodextrin in the peritoneal cavity. Adhesion formation and prosthetic behavior at the prosthesis/peritoneal interface were evaluated and quantified by sequential laparoscopy performed at 3, 7 and 14 days.
  
  
  RESULTS
  Adhesions generally formed on the tacks and were classified as the fully integrated type. No significant differences were observed in terms of the extent of adhesions or of neoperitoneal thickness between control animals and those receiving Ringer's lactate or icodextrin.
  
  
  CONCLUSIONS
  (a) Prosthesis-fixing tacks induced adhesions; (b) the use of substances such as icodextrin or Ringer's lactate does not seem to diminish adhesion formation, and (c) the use of icodextrin offered no benefits over that of Ringer's lactate solution.
