Summary
The rectovaginal fascia is present and fully developed in newborns, crucial for bowel function and surgical guidance in pelvic procedures. This finding clarifies its importance in pediatric anatomy.
Area of Science:
- Anatomy
- Embryology
- Pelvic Surgery
Background:
- The rectovaginal fascia's role in adult female pelvic anatomy is documented, linked to rectoceles and constipation.
- Its presence and development in pediatric populations remain unaddressed in surgical literature.
Purpose of the Study:
- To investigate the existence and development of the rectovaginal fascia in fetal and newborn specimens.
- To determine if this anatomical structure is present in children.
Main Methods:
- Plastination and histological staining of 31 male and 31 female fetal pelves (9 weeks gestation to newborn).
- Macroscopic and microscopic examination of fetal and adult cadavers.
- Analysis of transversal, sagittal, and frontal sections at magnifications up to 80x.
Main Results:
- The anlage (primordium) of the rectovaginal fascia was identified early in the fetal period.
- A distinct connective tissue fascia develops, connecting to the vaginal wall and separating the rectum and vagina.
- Neurovascular bundles were observed ventrolaterally to the rectal wall.
Conclusions:
- The rectovaginal fascia is fully developed in newborns, originating from differentiating mesenchyme.
- It compartmentalizes pelvic structures, supports the rectal wall for effective defecation, and aids surgeons in protecting pelvic autonomic nerves.
- Understanding and preserving this fascia is vital for surgical outcomes and pelvic organ function.
