The prognosis after rectal mucosal prolapse is age-related. In the case of young children, the prognosis is generally better. If it is an adult, the prognosis is generally worse, the specific situation is analyzed as follows: 1. Young children: pediatric rectal mucosal prolapse occurs in a short period of time and is easy to reset after prolapse. And there is no pain and infection, the possibility of self-healing is higher. For those who can’t be cured by themselves, most of them have better prognosis and fewer complications when they are cured by conservative treatment or surgery. 2. Adults: prolonged and repeated episodes of rectal prolapse in adults may easily lead to perianal nerve damage, anal incontinence, ulceration, perianal infection or rectal necrosis, or even intestinal obstruction. In case of patients with III degree rectal prolapse, even if surgical treatment is taken, the postoperative period will be characterized by easy recurrence and many complications. After rectal mucosal prolapse surgery, follow the doctor’s instructions to take good care of the patient to reduce the chance of complications and recurrence.
