Treatment methods
MYZZ, Z06106031, fistula
Surgical method: First, use a probe to gently probe along the direction of the fistula from the outer opening, pass through the entire fistula, and reach the inner opening. Cut all fistulas along the direction of the probe and open the entire length of the fistula. Make incisions on both sides of the skin of the open fistula, continue to deepen along the incision, and cut diagonally towards the deep part of the fistula to remove the entire fistula. The transverse section of the wound is V‐shaped. Patients in both groups received standard postoperative anorectal care, and the wound dressing was routinely changed on the second day after surgery. Patients were asked to avoid eating spicy and fried foods during treatment and maintain regular bowel movements. The Zibai ointment group received external application of Zibai ointment (People's Hospital Affiliated to Fujian University of TCM, MYZZ Z06106031) on the first day postsurgery, while the control group received external application of petroleum jelly (production license No.: Zhejiang Food and Drug Administration Equipment Production License No. 20100048). The wound healing time was recorded, and we compared the clinical efficacy between the groups.
