The difference between rectal prolapse and rectal procidentia mainly lies in the location and extent of the lesions, as well as the degree of the lesions. Rectal prolapse mainly includes internal rectal mucosal prolapse and external rectal mucosal prolapse, and external rectal mucosal prolapse is mainly referred to as rectal procidentia. Hence, rectal procidentia is a manifestation of rectal prolapse, while rectal prolapse is a generalized term for rectal procidentia. If it is an internal rectal mucosal prolapse, one can choose traditional Chinese medicine retention enema or oral medication for treatment. However, if rectal procidentia is confirmed and recurs, the only treatment method is surgery to excise the prolapsed mucosa. To prevent rectal prolapse or rectal procidentia, it is advised not to engage in excessive physical activities.
