Page Background

Anterior colporrhaphy is performed through an anteri-

or vaginal wall incision and plication of the vaginal tissues

in the midline using absorbable sutures. Recurrence

rates are high when using anatomic outcome criteria.

However, when contemporary ‘‘functional’’ outcome

measures are used, with appropriate selection of patients,

better results can be obtained

[38,39] .

The technique

of transvaginal rectocele repair allows correction of

fascial defects, by separating the rectum and vaginal

epithelium

[40] .

The relatively high recurrence and reoperation rates

(30%), especially after traditional (anterior/posterior) repair,

and the high success rates for using mesh in abdominal

hernia surgery and SUI surgery led to the quick adoption of

transvaginal mesh (TVM)-augmented pelvic floor repair

procedures. However, concerns have been raised on the

safety of TVM, with serious adverse events being reported.

The Food and Drug Administration issued a series of

statements on the safety of TVM and finally reclassified

TVM in prolapse repair into high-risk devices. The PROSPECT

multicentre RCT comparing traditional repair versus

synthetic mesh and biological grafts in

>

1000 women and

with 24-mo follow-up has recently been published

[41] .

The results showed no benefit from TVM- or biological graft-

augmented pelvic floor repair over the traditional repair in

both patient-reported outcomes (at 2 yr) and objective

outcomes (at 1 yr). In addition, there were no significant

differences in serious adverse events, dyspareunia rates,

recurrence of prolapsed, or reoperation rates for prolapse.

However, 12% of women in the synthetic mesh group

underwent reoperations for management of mesh compli-

cations. The authors concluded that in absence of any

benefit, synthetic mesh-augmented pelvic floor repair as a

primary prolapse procedure may pose unnecessary risks;

however, they emphasised the importance of long-term

follow-up.

Depending on the patient’s individual characteristics, the

treatment of a uterine/apical prolapse can entail hyster-

opexy or colpopexy, or hysterectomy with colpopexy

[40]

. A

variety of procedures exist for vault/uterine suspension for

women who are deemed fit for surgery; the two most

commonly performed procedures are sacrocolpopexy

(open/laparoscopic/robotic) and vaginal sacrospinous fixa-

tion (SSF). Other procedures include uterosacral vault

suspension and the rarely performed Infracoccygeal vaginal

sling (IVS).

Abdominal sacrocolpopexy (ASC) is the most durable

operation for advanced POP and serves as the criterion

standard with which other operations are compared

[40] .

ASC involves attaching the vaginal apex to the

sacral anterior longitudinal ligament reinforced with a

graft, usually synthetic mesh

[42,43]

. The Cochrane

review showed that compared with SSF, ASC was

associated with significantly fewer women being aware

of prolapse or requiring repeat surgery and lower rates

of postoperative dyspareunia. Long-term outcomes (7 yr)

for the well-designed CARE study reported that nearly

one-third of women who underwent ASC met their

composite definition of failure. The reoperation rate

was 16.7%—almost divided equally into one-third for

POP, one-third for SUI, and one-third for mesh-related

complications.

Colpocleisis (LeFort colpocleisis, colpectomy) is offered

to women with POP, who no longer wish to preserve

vaginal coital function. The technique consists of vaginal

closure +/– colpectomy. Colpocleisis is associated with high

success rates, and low recurrence and complication rates,

especially after the age of 80 yr

[44–46] .

Uterine suspension using nonabsorbable sutures has

widely been reported by laparotomy or laparoscopy

[47]

. The use of strips of skin

[48]

or fascia lata

[49]

for

uterine and bladder suspension has also been described.

Abdominal uterosacral ligament suspension (colpopexy)

consists of suspending the vaginal apex (mainly following

concomitant hysterectomy) to the uterosacral ligaments,

using nonabsorbable or absorbable sutures, laparoscopically

[50,51]

or by laparotomy

[52–54]

. It has been reported that

abdominal uterosacral ligament colpopexy (with concomi-

tant hysterectomy) was associated with an increased risk of

recurrence (6.2 times higher) when compared with ASC and

hysterectomy

[55]

. The long-term anatomical and functional

outcomes, and the exact number and nature of complica-

tions, are, at this moment, not well studied for these

procedures.

4.1.

Consensus view

In addition to a consensus discussion, careful consideration

of the European Commission’s Scientific Committee on

Emerging and Newly Identified Health Risks report on the

safety of surgical meshes used in urogynaecological surgery

[21]

was undertaken, and this consensus follows on from

and supports the deliberations of that panel.

A number of different types of potential materials can be

used in POP and SUI mesh surgery, which include the

following categories:

1. Allografts (eg, cadaveric fascia and dura mater)

2. Xenografts (eg, porcine and bovine)

3. Autografts (eg, fascia lata and rectus fascia)

4. Synthetic meshes (nonabsorbable, eg, PP mesh as well as

absorbable)

It is important to differentiate between the use of

synthetic MUSs for the treatment of SUI and large surface

areas of mesh for treating POP.

Based on the work with mesh in anterior abdominal

hernia repair, a classification of synthetic mesh material has

been reported

[56] .

A type 1 macroporous PP mesh has been

proposed as the most appropriate material for vaginal

implantation for SUI and POP, the principal characteristics

being that it should be monofilament with the pore size

being

>

75 microns. It is evident that a number of materials

had been evaluated in managing anterior abdominal wall

hernias until this classification was formulated. Careful

consideration needs to be given to the design and weave of

synthetic mesh materials, as these can have a significant

effect on efficacy and safety.
