Effects of Ringer's lactate, Interceed(TC7) and Gore-Tex Surgical Membrane on postsurgical adhesion formation
1Department of Obstetrics and Gynecology, McGill University, Montreal, Quebec, Canada.
Objective:
To evaluate the effects of Ringer's lactate instillation, Interceed(TC7) (Johnson and Johnson Medical, Inc., New Brunswick NJ), and Gore-Tex Surgical Membrane (W. L. Gore and Associates, Inc., Flagstaff, AZ) in a rat uterine horn model.
Setting:
Rats were in a conventional laboratory setting.
Participants:
Sprague-Dawley white rats, weighing 225 to 250 g.
Interventions:
The left uterine horn was subjected to a standardized lesion by serosal denudation and devascularization. The rats were randomly assigned into control group, Interceed(TC7) group, Gore-Tex group, and Ringer's lactate group.
Main Outcome Measures:
Degree of adhesions was evaluated 2 weeks after the initial surgery.
Results:
Adhesion score after Ringer's lactate instillation was significantly lower than those of control, Interceed(TC7), and Gore-Tex groups. Gore-Tex was associated with less adhesion formation than control. No difference was found in the adhesion formation between the Interceed(TC7) group and the control group.
Conclusion:
Confirming our previous observations, Ringer's lactate instillation is effective in decreasing adhesion formation. Gore-Tex reduces adhesion formation, but its efficacy is inferior to those of Ringer's lactate. Contrary to previous reports, Interceed(TC7) is ineffective in our animal model.
