Background:Perianal abscess is a common acute anorectal pyogenic disease (8%-25% of anorectal illnesses), mainly seen in men aged 20-40. Over 90% suffer severe postoperative pain, impairing healing, triggering anxiety or sepsis and raising medical loads. Western multimodal analgesia eases pain yet causes dependence and side effects. TCM sitz baths clear heat, reduce swelling and promote recovery. Few personalized combined protocols are available, and integrated Chinese-Western synergies are insufficiently exploited. This optimized integrated intervention guides postoperative pain nursing.
