A Cochrane review included 29 studies with a total of 3 227 subjects. One study examined pelvic pain and found no evidence of a difference between use of hydroflotation agents and no treatment. There was no evidence of benefit from the use of the antiadhesion agents in the live birth rate. The use of antiadhesion gels like hyaluronic acid decreased adhesion formation . When gels were compared with no treatment or with hydroflotation agents at second-look laparoscopy, fewer participants who received a gel showed a worsening adhesion score when compared with those who received no treatment and with those given hydroflotation agents.
| Outcome | Relative effect (95% CI) | Assumed risk - control= No hydroflotation agents | Corresponding risk - intervention= Hydroflotation agents (95% CI) | Number of participants (studies) |
|---|---|---|---|---|
| Improvement in pelvic pain | OR 0.65 (0.37-1.14) | 806 / 1000 | 730 / 1000 (606-826) | 286 (1) |
| Live birth rate | OR 0.67 (0.29-1.58) | 140 / 1000 | 98 / 1000 (45-205) | 208 (2) |
| Participants with adhesions at second-look laparoscopy | OR 0.34 (0.22-0.55) | 836 / 1000 | 635 / 1000 (529-738) | 566 (4) |
Comment: The quality of evidence is downgraded by study limitations (poor reporting of sudy methods) and by imprecise results (limited study size for each comparison).
