Effects of pirfenidone and dermoid cyst fluid on adhesion formation.

OBJECTIVE: To evaluate the effects of pirfenidone and human dermoid cyst fluid on adhesion formation in a rat model. DESIGN: A prospective, blinded, controlled study. SETTING: Sprague-Dawley white rats in a conventional laboratory setting. INTERVENTION(S): Rats were divided into four groups according to the type of solution tested (dermoid fluid, 0.05 mg of pirfenidone, normal saline, and a combination of dermoid fluid and pirfenidone). In the first experiment, the solution (0.5 mL) was injected intraperitoneally. In the second experiment, the solution was instilled intraperitoneally after a standardized injury to the right uterine horn. The degree of adhesion formation was evaluated 2 weeks after the initial surgery. RESULT(S): Human dermoid cyst fluid caused adhesion in 4 of 10 intact rats and in 9 of 10 standardized injured rats. Pirfenidone did not decrease adhesion formation. No adhesion was found after injection of saline or pirfenidone in intact rats. The mean +/- SEM adhesion score in standardized injured rats was higher in the dermoid group (4.6 +/- 0.6) than in the pirfenidone group (2.8 +/- 0.7) or the saline group (3.8 +/- 0.5). The mean +/- SEM adhesion score in intact rats was 0.6 +/- 0.3 after dermoid fluid injection and after dermoid instillation in standardized injured rats was 4.6 +/- 0. 6. CONCLUSION(S): Human dermoid fluid causes adhesion formation even in intact rats, and the adhesion is worse in the presence of serosal injury. Intraperitoneal pirfenidone does not decrease adhesion formation.[1]
