DISEASES
Common anorectal diseases like anal fistula can only be treated surgically. However, postoperative wound healing can be challenging and unpleasant due to the anatomical features of the lesion site and the surrounding area. Patients experience a great deal of discomfort due to the lengthy postoperative recovery period. Therefore, it is crucial to find efficient methods to improve wound healing following surgery for anal fistula. Clinical studies have shown that Zibai ointment is highly effective in the postoperative treatment of anal fistula. We designed this preliminary study to explore the potential effects of Zibai ointment on cell apoptosis in promoting wound healing. The details are reported in the following sections.
