title: Pharmacological adjuvants during infertility surgery: a systematic review of evidence derived from randomized controlled trials.
abstract: The aim of this study was to evaluate systematically the role of pharmacological agents used as adjuvants during infertility surgery to prevent or reduce postoperative adhesion formation and improve pregnancy rates. Meta-analyses were performed of the ten randomized controlled trials identified that evaluated the use of pharmacological adjuvants at infertility surgery. The administration of steroids, dextran 70, noxytioline, heparin, or promethazine have all been investigated for their adjuvant role in preventing adhesion formation during pelvic surgery for infertility. Outcome measures were taken as: pregnancy rates after infertility surgery; number of patients with absent, improved or deteriorated adhesions at second look laparoscopy (dichotomous outcomes); and changes in adhesion score from initial surgery to second look laparoscopy (ordinal outcome). None of the pharmacological adjuncts investigated in a randomized controlled fashion was shown to improve postoperative pregnancy rates. There was some evidence that steroids reduced the incidence or severity of postoperative adhesion formation; there was little evidence to support the use of dextran. The routine use of pharmacological adjuncts during infertility surgery cannot be recommended on the basis of the available evidence derived from randomized controlled trials. Dextran appears to offer no advantage. The evidence with regard to steroids is far from conclusive but tentatively indicates that they may be beneficial.
