Background
Rectal prolapse, with or without concurrent vaginal prolapse, is a debilitating condition. Despite debate regarding the optimal surgical approach, operative repair remains the mainstay of treatment. Our objective was to describe trends of rectal prolapse repair in Washington State.
Methods
A retrospective cohort of patients undergoing rectal prolapse repair was created from the Washington State Comprehensive Hospital Abstract Reporting System. Age- and sex-adjusted rates of rectal prolapse repair (RPR) alone and concurrent rectal and vaginal prolapse repair (CRVR), trends over time, and factors associated with variation in rates are described.
Results
There were 2755 hospitalizations in which patients underwent RPR, with 33.3% undergoing CRVR. Seventy-five percent of all repairs were in patients older than 50. Rates for rectal prolapse repair went from 3.72/100,000 people in 2008 to 3.25/100,000 people in 2019 (p = 0.003) and did not increase in patients ages 65–79 (p = 0.09) or older than 80 (p = 0.945). Perineal repairs accounted for 31% of repairs and declined after 2014. Minimally-invasive abdominal repairs doubled from 32.5% in 2008 to 65.4% in 2019 (p < 0.001). Seventy-five percent of patients lived within 20 miles of the treating facility.
Conclusions
Despite a broad shift towards abdominal, minimally invasive approaches, population-adjusted rates of rectal prolapse repair have remained stable in Washington State, even in elderly demographics in which rectal prolapse is more prevalent. Most patients receive operations at local facilities, but rates of repair vary with population size and number of surgeons, suggesting there are other factors driving care for rectal prolapse at a population level.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
