The clinical effect of Ma Yinglong hemorrhoid cream for anal fistula is very limited. Because once the diagnosis of anal fistula is confirmed, the principle of treatment for anal fistula is to choose early surgical excision or anal fistula hanging therapy. For anal fistulas with mild symptoms, infrequent onset, and occasional local inflammation and swelling, you can use Ma Yinglong hemorrhoid cream to apply topically to the red and swollen part of the fistula, which has a certain effect of reducing swelling and pain, but the effect is very limited. Clinically, for the treatment of anal fistula, the conservative method is to use erythromycin ointment, mupirocin ointment for external application or take Xinhuang tablets or small septic cream orally, which have the effect of clearing heat and detoxifying. But the conservative treatment can only relieve the basic symptoms of patients, and the final complete solution of anal fistula still needs to choose surgery.
