Clinical Trial Summary
A novel vaginal orthosis, or splint, made of silicone will be used daily to help support the
healing vaginal reconstruction during the post-operative phase from week 2 to week 12.
Description:
Background/Rationale:
Pelvic Organ Prolapse (POP) is the bulging or herniation of one or more pelvic organs into or
out of the vagina. A woman's estimated lifetime risk of POP is 30-50%, with 2-4% of women
being symptomatic. Approximately 300,000 women undergo surgical procedures in the United
States to repair POP every year. Recurrence rates of POP after native tissue repair utilizing
Sacrospinous Ligament Fixation (SSLF) or Uterosacral Ligament Suspension (USLS) vary based on
the definition of surgical or anatomic failure used, however a large RCT reports rate of
reoperation at 5 years of 8-11.9%.
With the use of the sacrospinous or uterosacral ligaments for apical support, the long axis
of the vaginal canal is deflected posteriorly in the pelvis leaving the anterior wall of the
vagina vulnerable to receive more of the downward forces produced intra-abdominally during
activity and with absolute increases in intra-abdominal pressure. Given this fact, it is not
a coincidence that the area of highest recurrence occurs, despite which definition is used,
in the anterior vaginal compartment.
Currently, the standard of care for post-operative management in patients who have undergone
native tissue pelvic reconstructive surgery is pelvic rest and reduced activity. The Voices
for Pelvic Floor Disorders (Voices PFD) in conjunction with the American Urogynecology
Society (AUGS) recommend pelvic rest for a minimum of 6 weeks and for activity to "be up and
around, but not too active" for the first two weeks, but to increase ambulation and activity
as able with guidance from primary surgeon. By the 6-week post-operative visit, most patients
are ready to begin to return to normal daily activities, but some may take a longer
time-period of reduced activity.
The "wound" healing process following vaginal surgery starts immediately after hemostasis is
achieved and the surgery is completed. The first stage is the inflammatory stage, which has
rapid onset and reaches maximal reaction within 1-3 days of surgery. This stage is driven by
migration of neutrophils and macrophages responding to factors released from the wound site
which are responsible for removal of debris and bacteria in order to prepare the site for the
second stage of healing, the proliferative stage. The aim of the proliferative stage is to
diminish the surgical site tissue area by contraction and fibroplasia, establishing a viable
epithelial barrier to activate keratinocytes. This stage is responsible for the closure of
the lesion itself, which includes angiogenesis, fibroplasia, and re-epithelialization. These
processes begin in the microenvironment of the lesion within the first 48 hours and can
unfold up to the 14th day after the onset of the lesion. With the re-epithelization initiated
and Type III collagen now deposited, the remodeling stage or wound maturation begins. The
ultimate goal of this third and final stage is to restore or achieve the maximal tensile
strength of the healing tissue. This is achieved mainly through the degradation of Type III
collagen and production of Type 1 collagen.
The objective of this project is to investigate whether patients who have undergone native
tissue pelvic reconstructive surgery for POP would benefit from a supportive intravaginal
orthotic device. Participants will be fitted for the device at 2 weeks after surgery with
daily use continuing until 12 weeks after surgery, thus providing stabilization during the
subepithelial wound healing process leading to improved tissue durability and viability along
the repaired vaginal walls.
