There are two main reasons why patients should not sit after perianal abscess surgery: First, perianal abscess surgery will leave traumatic openings in the skin around the anus, and sitting will lead to compression and squeezing of the traumatic openings, thus preventing the normal healing and growth of the wounds. At the same time, sitting will also lead to the lack of air circulation around the anus and slow circulation of blood in the veins around the anus, which will affect the normal healing of the wound. Secondly, there will be certain painful symptoms after perianal abscess surgery, and if you sit down, the wound will be squeezed, thus aggravating the painful symptoms and even causing the wound to crack. Therefore, it is best to take a lying position for recuperation after perianal abscess surgery, and not to defecate within 24 hours after surgery, and to sit down slowly after 5-7 days in general in case of good recovery.
