title: Laser laparoscopy versus laparotomy in lysis of pelvic adhesions.
abstract: Severe adhesions were induced at laparotomy by laser ablation of the surface of one uterine horn and 1 cm2 of pelvic sidewall in 20 rabbits. Three weeks later the rabbits were selected at random for laparoscopy or laparotomy. Adhesions at the horn, sidewall and incidental sites were scored and lysed with laser at similar power densities. Three weeks later animals were killed and adhesions were blindly scored. We found a significant and similar reduction in severe adhesions at uterine horns after either laser laparoscopy or laser laparotomy, better lysis of sidewall and incidental adhesions by laser laparoscopy and formation of de novo adhesions at nonoperative sites after laparotomy but not after laparoscopy. We conclude that (1) de novo adhesions are common after laparotomy; (2) severe uterine horn adhesions can be reduced equally well by both laparoscopy and laparotomy but laparoscopy is superior to laparotomy with less severe peripheral adhesions; (3) outcome of adhesiolysis depends on several variables, including adhesion density and location and approach (laparotomy or laparoscopy), even when the tool (laser) is constant.
