Internal rectal intussusception (rectal intussusception, internal intussusception, internal rectal prolapse, occult rectal prolapse, internal rectal procidentia and rectal invagination) is a medical condition defined as a funnel shaped infolding of the rectal wall that can occur during defecation.
This phenomenon was first described in the late 1960s when defecagraphy was first developed and became widespread. Degrees of internal intussusception have been demonstrated in 40% of asymptomatic subjects, raising the possibility that it represents a normal variant in some, and may predispose patients to develop symptoms, or exacerbate other problems.

Famous quotes containing the word internal:
“Personal change, growth, development, identity formation—these tasks that once were thought to belong to childhood and adolescence alone now are recognized as part of adult life as well. Gone is the belief that adulthood is, or ought to be, a time of internal peace and comfort, that growing pains belong only to the young; gone the belief that these are marker events—a job, a mate, a child—through which we will pass into a life of relative ease.”
—Lillian Breslow Rubin (20th century)
