Compound Phellodendron Decoction May Promote Wound Healing After Anal Fistulotomy

All patients underwent anal fistulectomy based on the Parks classification. For postoperative infection prophylaxis, cefuroxime was used at a dosage of 2g per dose, twice daily. Commencing the day following surgery, a fumigating-washing therapy was conducted once daily either after defecation or two hours prior to intravenous infusion. In the study group, a medical solution used for fumigating-washing therapy was prepared by blending 200 ml of CPD with 2 liters of water at 40 °C. This medicinal solution was then transferred into the reservoir of an ultrasonic atomizing fumigating-washing device (Model:TM50-C, Xuzhou Tianma Medical Equipment Factory, China) that was classified by the FDA as Class II (special controls).
