Internal Rectal Prolapse

Internal rectal prolapse (IRP), also known as internal rectal prolapse or internal procidentia, accounts for a proportion of cases clinically classified as grade I rectal prolapse, alongside rectal mucosal prolapse. Mucosal prolapse most commonly occurs in the middle and upper parts of the anterior rectal wall. It is a type of defecatory disorder and is also known as internal rectal intussusception (internal proctoptosis) or occult rectal prolapse. Clinically, it is classified as “rectal prolapse” based on positive examination findings, but as “constipation” based on its clinical presentation. There is no specific name for internal rectal prolapse in TCM literature; based on the distinct characteristics of its clinical symptoms and signs, it is included under “rectal prolapse” in TCM literature.
