0 a Latin word meaning "prolapse" (= a condition in which an organ has moved down out of its usual position), used in medical names and descriptions
Procidentia usually refers to uterine prolapse, but rectal procidentia can also be a synonym for rectal prolapse.
Internal rectal intussusception (occult rectal prolapse, internal procidentia) can be defined as a funnel shaped infolding of the upper rectal (or lower sigmoid) wall that can occur during defecation.
Minor prolapse can be treated with exercises to strengthen the pelvic floor muscles; more serious prolapse, e.g., complete procidentia, requires pessary use or reconstructive surgical treatment.
