Title: Apical Prolapse
1Apical Prolapse
2Overview
- Apical prolapse is one type of POP and refers to
the downward displacement of the vaginal apex. - Support of the vaginal apex is primarily derived
from the integrity of the Uterosacral and
cardinal ligaments, the continuity of the fibro
muscular layer surrounding the vagina, and a
neuromuscularly intact levator ani. - The etiology of apical prolapse is likely related
to connective tissue, neural, and/or muscular
defects in these normal supports. - It is rare to find isolated support defects of
the anterior or posterior vaginal walls or an
isolated apical defect since the defects in the
connective tissue, neural pathways, and muscle
are not confined to one small site Therefore, if
an anterior or posterior prolapse is diagnosed,
one should examine the patient carefully
(preferably standing) to ensure that a
concomitant apical defect is not present as well.
- Many experts believe that adequate suspension of
the apex is the cornerstone of any successful
prolapse repair. If the vaginal muscularis is
intact and well suspended at the apex, many
anterior and posterior defects will also resolve - The most common risk factors for developing
prolapse are vaginal delivery and previous
hysterectomy - The incidence of surgical repair for apical
prolapse is increased in any woman who has had a
prior hysterectomy, and even further increased in
women who have had a hysterectomy for prolapse
Therefore, some type of apical suspension should
be done at the time of every hysterectomy.
3CLINICAL MANIFESTATIONS
- The most common symptom of clinically significant
apical prolapse is a protrusion of tissue from
the vaginal opening. - . Women with prolapse may also report a sensation
of pelvic pressure, voiding difficulty, a need to
splint to urinate or defecate, bowel symptoms,
and pelvic or low back pain. -
- The prolapsed vagina may protrude on standing,
leading to chronic discharge and bleeding from
chronic ulceration. Rare cases of vaginal
evisceration have been reported in prolapse that
has been chronically neglected. - Traditionally, experts believed that these
symptoms became progressively worse as the
prolapse gradually increased over time. - Several well-designed studies have shown that low
back and pelvic pain are not associated with
prolapse and that many pelvic floor symptoms,
particularly bowel symptoms, do not increase with
advanced stage prolapse
4DIAGNOSIS AND PREOPERATIVE EVALUATION
- History
- Women with symptomatic apical prolapse should
undergo a careful history which focuses on
related pelvic floor symptoms, given that pelvic
floor disorders rarely occur in isolation. - They should be questioned about concomitant
urinary incontinence, voiding difficulties, fecal
incontinence, and defecatory problems. - Since prolapse is a quality of life disorder, it
is also essential to determine which symptoms are
most bothersome to the individual patient and to
tailor a treatment plan accordingly
5DIAGNOSIS AND PREOPERATIVE EVALUATION
- Physical examination
-
- A thorough speculum and bimanual examination
should be done. - The apical prolapse can be visualized during
speculum examination with the woman straining as
the speculum is slowly withdrawn from the upper
third of the vagina. It is often helpful to use
half of the speculum, placed posteriorly to
examine the anterior wall and apex, then placed
anteriorly to examine the posterior wall. - The anterior vaginal wall is frequently the most
prolapsed vaginal segment, even in women with
apical prolapse. It is important to identify the
position of the apex. - Women should also be examined in the standing
strain position to maximize the prolapse and aid
in identification of other defects in pelvic
support that will require concomitant repair.
Theoretically, an operation that corrects all
existing defects may decrease the likelihood that
a subsequent operation will be necessary - The findings of the examination should be
recorded using a quantitative and reproducible
method for recording pelvic organ prolapse. -
- The system currently recommended by the
International Continence Society and the American
Urogynecologic Society is the Pelvic Organ
Prolapse Quantification (POP-Q) system
6DIAGNOSIS AND PREOPERATIVE EVALUATION
7DIAGNOSIS AND PREOPERATIVE EVALUATION
- Evaluation for urinary dysfunction
-
- Apical prolapse frequently coexists with lower
urinary tract dysfunction urinary incontinence
and urinary retention are common, so a thorough
apical prolapse evaluation should assess for
both. - Urinary retention can be evaluated by checking a
post void residual urine volume (PVR) within 10
minutes of the patient voiding. In general, a PVR
of less than 50 mL is considered adequate
emptying, and a PVR greater than 200 mL is
considered inadequate. Ninety percent of elevated
post-void residual urine volumes normalize after
surgical correction of prolapse. - Many women with advanced apical prolapse remain
continent despite loss of anterior vaginal and
bladder/urethral support. However, 8 to 40
percent of continent women develop symptoms of
stress urinary incontinence after - surgical correction of the prolapse.
- Urethral pressure measurements and
electromyography performed during urodynamics in
women with advanced prolapse suggest that the
prolapse "kinks" or obstructs the urethra, thus
maintaining continence. - Therefore, to identify "occult" or "potential"
stress incontinence, all women with apical
prolapse should have a preoperative evaluation of
stress continence with the prolapse reduced. In
addition, all women having surgical - correction of prolapse should be counseled
regarding the potential for postoperative
incontinence. - In a large randomized trial, the Colpopexy and
Urinary Reduction Efforts (CARE) trial, stress
continent women with stage II to IV apical
prolapse underwent preoperative urodynamics
testing . When testing was performed without
reduction of the prolapse, only 3.7 of
participants exhibited SUI. Women who had SUI
with prolapse reduction prior to surgery and then
underwent sacral colpopexy alone (without
concomitant incontinence surgery), had a
significantly increased risk of postoperative
SUI. The results of different methods of prolapse
reduction (manual, pessary, speculum, swab,
forceps) were variable a swab was the method
most likely to predict postoperative stress
incontinence, and a pessary was the least likely
8OPTIONS FOR SURGICAL THERAPY
- Colpocleisis
-
- Women who do not desire future vaginal
intercourse and/or are in poor general health may
consider an obliterative procedure, such as
Colpocleisis. - Colpocleisis is highly effective with low
morbidity for correcting apical prolapse in such
women - Procedure
-
9Colpocleisis
- The procedure is performed under general or
spinal anesthesia and can be done with the uterus
in situ or after hysterectomy - . Concomitant hysterectomy at the time of
Colpocleisis increases morbidity without
improving surgical success - Using sharp and blunt dissection, the vaginal
epithelium is dissected from the underlying
muscularis. A total Colpocleisis removes all of
the vaginal epithelium, while a partial
Colpocleisis leaves a small portion of vaginal
epithelium on each side to provide drainage
tracts in women with a uterus - The leading edge of the prolapse is identified
and successive interrupted sutures are used to
reduce the prolapse until it lies above the
levator plate, effectively obliterating the
vaginal canal. Care should be taken not to pull
the posterior urethra down when suturing the
anterior and posterior vagina. - Finally, a wide perineorrhaphy is created by
removing a large diamond shaped area of perineal
skin and distal vaginal epithelium. The levator
muscles are then approximated with non-absorbable
sutures. The area from above the rectum to the
urethrovesical junction should be closed
10Colpocleisis
- Complications
-
- Significant postoperative complication rates
occur in approximately 2 percent of patients and
are frequently attributed to the older age and
frail condition of patients selected for this
procedure. - Transfusion is the most commonly reported major
complication related to the surgery itself. -
- Some women develop stress urinary incontinence
after Colpocleisis, which, as described, is
likely secondary to "un-kinking" the urethra. -
- Optimal management of potential stress
incontinence is unclear. Most women choose
Colpocleisis for its simplicity and quick
recovery and wish to avoid the morbidity of an
additional major continence procedure. - Performance of a minimally invasive mid-urethral
sling may be appropriate in these cases however,
the role of this procedure at the time of
Colpocleisis has not been studied.
11OPTIONS FOR SURGICAL THERAPY
- Vaginal versus abdominal procedures
- In women who desire a reconstructive procedure,
route of access should be determined based on
risks, benefits, and complications of abdominal
and vaginal surgery, as well as the use of
synthetic meshes. - This may be the most controversial area in the
treatment of apical prolapse, subject to debate
amongst experts with ample evidence from
observational studies supporting both sides. - In the past, gynecologic surgeons favored the
vaginal approach for its low complication rates
and quick recovery however, abdominal routes
have gained popularity more recently - Evidence from randomized trials has demonstrated
that abdominal repairs are more durable, while
vaginal repairs have fewer complications,
including foreign body complications. - Choosing a vaginal or abdominal route to correct
apical prolapse must be individualized based on
patient expectations, goals, and wishes. While
the abdominal route seems to have increased
durability, it comes at the expense of a longer
recovery period and possibly more complications. - A younger, active woman may choose the higher
success of abdominal sacrocolpopexy, accepting
the longer recovery and potential for foreign
body erosion. In contrast, a frail, elderly woman
may opt for a higher chance of recurrence in
exchange for a quicker return to her daily
activities - Given these data, recommendations regarding
surgical approach among pelvic surgeons differ
dramatically based on their own experiences and
biases
12VAGINAL APICAL SUSPENSION PROCEDURES
- Sacrospinous ligament suspension
- Sacrospinous ligament suspension is the
best-studied vaginal procedure for treating
apical prolapse. Anatomic cure rates after
Sacrospinous ligament suspension range from 63
to 97 percent. -
- The failure rate is relatively low when the
procedure is performed for apical prolapse 2 to
11 percent, depending on criteria for failure,
but is high when performed for anterior vaginal
wall prolapse 4 to 40 percent. - . Therefore, women with large anterior wall
defects in addition to apical defects may benefit
from another type of prolapse repair, which more
directly addresses the anterior vagina. - Randomized trials have shown that Sacrospinous
ligament suspension is slightly inferior to
abdominal sacrocolpopexy in anatomic restoration,
but results in similar patient satisfaction -
- Procedure
- Sacrospinous ligament suspension is generally
performed unilaterally. Some surgeons have
proposed bilateral Sacrospinous ligament
suspension, although the value of this
modification has not been proven - . The bilateral technique depends upon adequate
vaginal length and depth - Am J Obstet Gynecol 1996 and 2004
13Cont. Sacrospinous ligament suspension
- Before starting the procedure, the surgeon must
ensure that the vagina is long enough to reach
the Sacrospinous ligament without a suture bridge
since a vagina shortened from previous vaginal
surgery may preclude Sacrospinous ligament
suspension. - Marking sutures are placed on the vaginal
epithelium at the site where it is going to
attach to the ligament. - The posterior vagina is opened in the midline
from the perineal body to the apex. - The vaginal epithelium is then separated from the
underlying muscularis and the dissection
continued to the level of the ischial spine. - The rectovaginal space is opened by gently
pushing the rectum medially, and the rectal
pillar is perforated. - Once the perirectal space is entered, the ischial
spine can be palpated and the ligament can be
found medially. - A long right angle retractor, e.g.,
Briesky-Navratil, is placed on the ischial spine
to protect the pudendal neurovascular bundle and
another is used to retract the bladder superiorly
and the rectum medially. - Once the ligament is clearly visible, two to
three permanent sutures are placed through the
ligament approximately one and one-half
finger-breadths medial to the ischial spine. - Several techniques and devices are available to
assist placing the suture through the ligament
(Miya hook, Deschamps ligature carrier). - After securing the sutures to the ligament
complex, each of the sutures is placed through
the muscularis on the undersurface of the
posterior vaginal epithelium and tied by a pulley
stitch, while the free end of the suture is held.
- Traction on the free end of the suture draws the
vaginal apex directly onto the Sacrospinous
ligament. - A common modification of this technique is the
"Michigan Modification - . In the Michigan Modification, all four vaginal
walls are directly approximated to the
Sacrospinous ligament (instead of just the
posterior vaginal wall), theoretically decreasing
the risk of anterior vaginal wall recurrence. The
point on each vaginal wall that reaches the
ligament is identified and the intervening vagina
excised. The sutures are placed through the
Sacrospinous ligament, as described above, then
sewn to the anterior and posterior vagina and
tied to the ligament.
14Cont. Sacrospinous ligament suspension
- Complications
- Complications after Sacrospinous ligament
suspension are uncommon. Intraoperative
hemorrhage from laceration of the pudendal
vessels is the most frequent complication.
Pudendal hemorrhage is best treated by tightly
packing the ischiorectal fossa and waiting for
homeostasis to occur. Cystotomy and enterotomy
are rarely reported. - Injury to the branches of the sciatic nerve that
cross the coccygeus muscle-Sacrospinous ligament
complex (C-SSL) is another possible source of
postoperative pain or nerve dysfunction. One
approach to decrease nerve entrapment is to
perforate the Sacrospinous ligament with the
needle in a vertical rather than a horizontal
orientation - However, if the sciatic nerve is entrapped in the
suture despite careful surgical technique, the
classic triad of sciatic entrapment occurs. The
patient typically awakens with severe buttock
pain radiating down the posterior leg. Delay in
diagnosis and treatment can result in permanent
neuropathy therefore, regional anesthesia of
prolonged duration should not be used for this
type of surgery and the patient should be taken
back to the operating room immediately upon
diagnosis to have the sutures removed. - Postoperative bowel complications are rare as the
procedure is meant to be extra peritoneal.
15Iliococcygeus suspension
- Iliococcygeus suspension is performed similar to
the Sacrospinous colpopexy, but uses the
Iliococcygeus fascia over the levator plate
instead of the Sacrospinous ligament. The
literature on this operation is sparse however,
subjective success rates appear to be similar for
Sacrospinous and Iliococcygeus suspensions, while
objective success after Sacrospinous ligament
suspension is 14 higher than after Iliococcygeus
suspension - reported advantages of the Iliococcygeus
suspension include less frequent anterior vaginal
wall recurrence and injury to the pudendal
neurovascular bundle, although these benefits are
not supported by any data. - Complications are similar to those described
above for Sacrospinous ligament suspension.
16Uterosacral ligament suspension
- Procedure
- The key to successful Uterosacral ligament
suspension is simultaneous correction of all
defects in the apical endopelvic fascia. In the
most commonly performed modification of the
Uterosacral ligament suspension , the anterior
and posterior vaginal walls are opened in the
midline and the enterocele sac identified. The
peritoneal cavity is entered and the Uterosacral
ligaments identified. An Allis clamp can be used
to tent the Uterosacral ligament making it easier
to identify. - The rectum is retracted medially
- Three permanent sutures are placed 1.5
centimeters medial and 1.5 centimeters posterior
to the ischial spine through the Uterosacral
ligament on each side - The sutures are numbered sequentially, 1 through
6, to facilitate vaginal placement. One arm of
each permanent suture is placed through the
anterior endopelvic fascia and the other through
the posterior endopelvic fascia. The sutures are
placed serially across the width of the vaginal
apex. All sutures are then tied, re-approximating
the anterior and posterior endopelvic fascia,
closing any potential enterocele defect, and
elevating the vaginal apex toward the sacrum - Cystoscopy should be performed after tying the
sutures due to a significant rate of ureteral
kinking during this procedure
17Uterosacral ligament suspension
18Uterosacral ligament suspension Cont
- Complications
- Intra and postoperative complications after
Uterosacral suspension are uncommon. Routine
Cystoscopy should be done at the completion of
each case before the patient leaves the operating
room to prevent delayed recognition of ureteral
injuries. Ureteral kinking from the Uterosacral
suture is found during routine Intraoperative
Cystoscopy in up to 11 percent of cases. If both
ureters do not efflux briskly, the most lateral
suture (closest to the ureter) on that side
should be removed. Typically, removing this
suture is sufficient to restore brisk ureteral
efflux without further sequelae, although
ureteral injury requiring uretero-neocystectomy
has been reported - The sacral nerves can be ligated if Uterosacral
ligament suspension sutures are placed lateral to
the ligament fibers or too deep into the pelvic
sidewall.
19Abdominal sacral colpopexyLaparoscopy and
Laparotomy
- Abdominal sacral colpopexy is the most durable
apical prolapse procedure - The most common procedure is sacral colpopexy
(attachment between the sacral promontory and the
upper vagina) sacral hysteropexy (attachment
between the sacral promontory and the lower
uterus) and sacral cervicopexy (attachment
between the sacral promontory and the cervix) are
uncommon - Anatomic success rates after sacral colpopexy
range from 76 to 100 - Am J Obst Gynecol 2002
20sacral colpopexy
21Abdominal sacral colpopexy Laparoscopy and
Laparotomy
- Procedure
- Abdominal sacral colpopexy involves attaching a
permanent mesh to the anterior and posterior
vagina, and then attaching the free end of the
mesh to the anterior longitudinal ligament of the
sacrum, which reestablishes a somewhat horizontal
vaginal axis . A commonly performed technique is
to carefully open the presacral space and expose
the anterior longitudinal ligament of the sacrum.
- Two or three permanent sutures are placed through
the anterior longitudinal ligament just below the
promontory when sutures are placed lower on the
sacrum, at the S3 to S4 level, presacral
hemorrhage is more common. - Next, a permanent mesh is attached to the
posterior vagina to the level of the rectal
reflection and to the anterior vagina for a
distance of several centimeters. Two rows of
permanent sutures should be used to widely attach
the mesh to the vagina to distribute the tension.
- The free end of the mesh is attached to the
anterior longitudinal ligament using the
previously placed sutures. Failure to attach the
mesh anteriorly results in anterior vaginal wall
recurrence rates of almost 30 . - prophylactic Burch colposuspension should be
performed at the time of abdominal sacrocolpopexy
in women without preoperative symptoms of stress
incontinence
22Abdominal sacral colpopexy Laparoscopy and
Laparotomy
- Complications
- Cystotomy (3.1 percent), enterotomy (1.6
percent), incisional problems (4.6 percent),
ileus (3.6 percent), thromboembolic event (3.3
percent), and transfusion (4.4 ) - . Presacral hemorrhage is the most concerning
intra-operative complication and can have
life-threatening consequences. The presacral
plexus of veins and the middle sacral artery can
be lacerated during the presacral dissection,
particularly if done at the S3-S4 level.
Reconstructive surgeons should be prepared to
manage presacral hemorrhage and have bone wax,
concave thumbtacks, and thrombin immediately
available.
23POSTOPERATIVE CARE
- Postoperative care is similar regardless of
surgical approach. However, recovery after sacral
colpopexy may be slower due to the abdominal
incision. Few data are available to guide
postoperative care and most recommendations are
based on the surgeon's experience and preferences - Ambulation The woman can begin walking with
assistance as soon as the day of surgery -
- Diet Women undergoing vaginal approaches can
frequently tolerate oral intake the evening of
surgery, and those having abdominal surgery the
morning after surgery -
- Bladder drainage The urinary catheter placed
preoperatively is left in place postoperatively
as women frequently cannot empty their bladders
immediately after pelvic and/or vaginal surgery,
particularly if a concomitant continence
procedure was done. The catheter can be removed
on the first postoperative day in the absence of
an intra-operative bladder injury, but a
post-void residual urine volume should be checked
to ensure complete bladder emptying. Continuous
bladder drainage is not required - Lifting Most surgeons place some lifting
restrictions on patients after surgery, although
these range dramatically from surgeon-to-surgeon.
It is probably reasonable to suggest a moderate
short-term lifting restriction, such as 10 pounds
for two weeks, then resume-lifting activities as
tolerated. This area has not been examined
extensively, with a notable exception. One study
found that there was no greater increase in
intra-abdominal pressure with lifting 20 to 35
pounds or doing jumping jacks than simply rising
from a chair . Satisfaction after surgery
correlates with patient goal achievement, many of
which are related to life-style, thus long-term
lifting restrictions are probably not necessary
or advisable - Nothing should be placed in the vagina (tampons,
coitus) until complete healing occurs, typically
in three to four weeks - Return to normal activities Patients may resume
normal activity (including sports) and return to
work when they are no longer experiencing pain or
fatigue related to surgery. A postoperative
examination should be performed to ensure
complete healing and assess outcome of the repair
