Apical Prolapse
Vaginal apex is
the keystone
Any surgical correction
of the anterior and posterior
walls will fail if the apex is
not adequately supported
Procedures for Apical Support
 Sacral colpopexy
 Sacrospinous ligament fixation
 Utero-sacral ligament suspension
 Ilio-coccygeus suspension
 Vaginal mesh systems such as Prolift, Avaulta,
Perigee/Apogee and etc.
Apical Prolapse Surgery
 Cochrane Database Analysis for abdominal sacral colpopexy versus
vaginal sacrospinous colpopexy
 3 trials (Benson 1996; Lo 1998; Maher 2004)
 Abdominal sacral colpopexy was better than vaginal colpopexy in terms
of
 Lower rate of apical recurrence (3/84 vs 13/85; RR 0.23, 95% CI 0.07
to 0.77)
 Higher success rate (The number of women failing to improve to
Stage 2 or better) (3/52 vs 13/66; RR 0.29, 95% CI 0.09 to 0.97)
 Lower postoperative dyspareunia (7/45 vs 22/61; RR 0.39, 95% CI
0.18 to 0.86)
 No significant difference in reoperation rate for prolapse (6/84 vs 14/85,
RR 1.46, 95% CI 0.19 to 1.11)
 Sacrospinous colpopexy was
 Quicker
 Cheaper
 Faster return to normal activities
 The data were too few to assess other clinical outcomes and complications
Maher et al. Neurourology and Urodynamics 2008
Sacral Colpopexy
Abdominal Sacral Colpopexy
 Elevation of vaginal vault to Sacral 2 utilizing a
mesh bridge
 Abdominal, laparoscopic, or robotic approach
 May change the vaginal axis (if sacral promontory
is used)
 85-90% success rate
 May be done with cervical preservation as a
cervicopexy
 Mesh erosion around 3-5 %, higher with
concomitant hysterectomy

abdominal sacrocolpopexy is associated with less
blood loss, shorter lengths of stay, and longer operative

 Costs of robotic sacrocolpopexy are higher than
laparoscopic
 Short-term outcomes and complications are similar
 Primary cost differences resulted from robot
maintenance and purchase costs.

Systematic Review of Robotic
Sacrocolpopexy
Hudson et al FPMRS 2014
 13 studies were selected for the systematic review.
 Meta-analysis yielded a combined estimated success
rate of 98.6% (95%CI 97.0–100%)
 The combined estimated rate of mesh
exposure/erosion was 4.1% (95%CI 1.4–6.9%)
 The rate of reoperation for mesh revision was 1.7%
Systematic Review of Robotic
Sacrocolpopexy
Hudson et al FPMRS 2014
 The rates of reoperation for recurrent apical and non-
apical prolapse were 0.8% and 2.5%
 The most common surgical complication (excluding
mesh erosion) was cystotomy
 (2.8%), followed by wound infection (2.4%).

 While some difference (up to around 25 minutes) in
average Console Times exists for FA with different
experience levels, these time differences are not
sufficient to claim a statistically significant distinction
Does the Time of the Robotic
Procedure Matter?
 Specifically, the impact of the shift change in the
afternoon
 Cases which start before 11am were significantly shorter
than those that start after 11am
 The average difference was 12 minutes
The Role of a Dedicated Anesthesia
Provider
 Effect of a highly experienced Anesthesia
Provider on OR time and specifically surgery
prep time was studied
 No significant difference in total OR times
(which may be due to the effects of other
factors)
 However, prep times was significantly different
The Most Optimal Team Configurations
Based on the Stochastic Model
 The optimization tool can be used at a hospital to
determine the `best’ surgical team assignments for any
set of available team members with known experience
levels
Practical Implications of
the Stochastic Model
 If a Surgeon has low experience, it is better to match him
with more experienced First Assistant
 If a Surgeon has high experience, it is fine to match him
with less experienced First Assistant and Scrub
Technician
 If both the Surgeon and First Assistant are not as
experienced it is better to match them with an
experienced Scrub Technician
Practical Implications of
the Stochastic Model
 A low-experienced Scrub Tech should be matched with
either a more-experienced Surgeon or First Assistant
 We do not recommend to team up a low-experienced
Surgeon, First Assistant, and Scrub Tech
 If the anesthesia provider has more experience, it is fine to
have a less experienced Circulating Nurse, however if
anesthesia provider has less experience, it is best to match
with a more experienced Circulating Nurse
 Low-experienced Circulating Nurse should be teamed with
an experienced Surgeon or vice versa
