Summary
Parity plays a limited role in rectal prolapse development. While women with rectal prolapse had more children, nulliparous women are also at risk, indicating other contributing factors.
Area of Science:
- Gastroenterology
- Gynecology
- Colorectal Surgery
Background:
- Rectal prolapse predominantly affects women, yet the role of parity in its development is understudied.
- Understanding risk factors is crucial for effective prevention and management of rectal prolapse.
Purpose of the Study:
- To investigate the association between parity and the occurrence of intra-anal and external rectal prolapse in women.
- To clarify the contribution of childbirth history to the pathogenesis of rectal prolapse.
Main Methods:
- Retrospective review of 354 defecography studies in female patients over a 10-year period.
- Inclusion criteria: intra-anal and external rectal prolapse; Exclusion criteria: intrarectal or hidden prolapse.
- Comparison of obstetric histories between patients with rectal prolapse (n=27) and controls (n=88).
Main Results:
- A higher proportion of nulliparous women were observed in the rectal prolapse group compared to the control group.
- Parous women with rectal prolapse had a significantly higher average number of children (3.3) than parous women without prolapse (2.5) (P=0.03).
Conclusions:
- Childbearing appears to be a limited factor in the pathogenesis of rectal prolapse.
- The development of rectal prolapse likely involves multiple factors beyond parity, as nulliparous women are also susceptible.
