High-molecular weight dextran in human infertility surgery.
The use of intraperitoneal 32% high-molecular weight dextran 70 (Hyskon, Pharmacia Inc.) has been reported to reduce the incidence of surgical adhesions in several species. The present study was undertaken to determine the effect of 32% dextran 70 in human females who underwent major abdominal infertility operations. Adhesions were quantitated by means of standardized objective criteria in 44 women in a prospective, randomized, double-blind study, and reevaluated at second-look laparoscopy approximately 6 weeks later. The mean change in the adhesion score for all patients in the 32% dextran 70 group (n = 23) was -2.57 units (i.e., clinically "improved") versus +2.41 units (i.e., clinically "worsened") in the control group (n = 21), p = 0.016. For the subgroup of patients who underwent lysis of adhesions, the 32% dextran 70 group (n = 17) improved significantly, whereas the control group (n = 12) tended not to improve with careful technique alone (-4.2 units versus +0.3 unit, p less than 0.05). These data indicate that 32% dextran 70 not only significantly reduces the formation of adhesions overall in human infertility operations, but also is highly effective in reducing the reformation of adhesions after lysis.
