Obstetrical sphincter injury
• 3-5% clinical; up to 27% by ultrasound
–Primipara>mulitpara
–Risk factors
• Instrumental delivery
• Prolonged second stage
• Fetal macrosomia
• Persistent occipito-position
• ? Episiotomy
–Midline>medilateral
• Impaired continence
–13-17% following primiparous vaginal delivery
–Up to 50% following 3rd-4th degree tear [level 2]
Immediate sphincter repair
• Apposition vs. overlap repair
–Inadequate evidence to favor either type
[level 1]
• Delayed repair
–Safe to delay for expert [level 2]
• Laxative >constipating regimens [level 1]
Sphincteroplasty
secondary reconstruction
• Evaluation
–Endorectal ultrasound
• 2-D/3-D
• MRI, fMRI, defecating proctography [level 4]
• Treatment
–<1 quadrant defect- conservative
–>1 quadrant defect- sphincteroplasty
Sphincteroplasty
results
• Overlapping repair
–? Direct repair
–? Individual repair of EAS ad IAS
• ‘good to excellent results’ 60-80%
–Results deteriorate with time [level 2]
–No reliable predictors of outcome available
Recommendations
• Sphincter repair is indicated for patients with
acute traumatic sphincter disruption, such as
following obstetrical injury, but many patients
experience persisting symptoms. GRADE B
• Overlapping sphincteroplasty can be offered to
patients with significant fecal incontinence and a
documented sphincter injury. Most patients
improve after sphincteroplasty, but outcomes
deteriorate over time. GRADE B
Postanal repair
• Described 1975
• Rarely performed today
• ‘Success’ rates 21-89% [level 3]
• Results deteriorate with time
Recommendation
• Postanal repair can be performed with
modest success in carefully selected
patients. However, this procedure is now
rarely performed due to the advent of
newer treatments. GRADE C
Non-stimulated muscle
transposition
• Gracilis vs. gluteus
• Up to 81% ‘success’ but results highly
variable [level 3]
• Rarely performed today
Recommendation
• Non-stimulated muscle transposition repair
can be performed with modest success in
carefully selected patients. However, this
procedure is now rarely performed due to
the advent of newer treatments GRADE C
Stimulated muscle
transposition
• Gracilis
• 55-85% ‘success’ [level 2]
• Substantial morbidity (up to 100%)
–Early- infection
–Late- erosion, pain, obstructed defecation
• Salvage procedure in select centers
–Restore tissue loss
–Surgeon experience critical
Recommendation
• Stimulated muscle transposition has been
shown to have reasonable success but is
associated with significant morbidity. It
remains a useful technique in selected
patients with significant perineal tissue
loss or in those who have failed other
treatments. GRADE C
Artificial sphincter
• Predominantly extrasphincteric
• 40-83% intention to treat success [level 2]
• Substantial morbidity (re-operation 46%)
–Early- infection
–Late- erosion, pain, obstructed defecation
• Select centers
–Surgeon experience critical
Recommendation
• Artificial anal sphincter has been shown to
have reasonable success but is
associated with significant morbidity. It
remains a useful technique in carefully
selected patients, particularly those who
have failed other treatments. GRADE B
Sacral Nerve Stimulation
• Most significant advance since last
consultation
• Minimally invasive
• Low morbidity
• Therapeutic trial (PNE) before definitive
procedure
• Expanding indications
–Sphincter defect [level 3]
Sacral Nerve Stimulation
results
• Variable reporting
–Decreased incontinent episodes 50-100%
–Decreased incontinence scores 50-80%
• Outcomes
–Severity [level 2]
–Quality of life [level 2]
–Safety [level 2]
–Cost-benefit [level 2]
Recommendation
• SNS is an effective therapy for most
patients with clinically significant
incontinence who fail conservative
management. The technique is safe,
minimally invasive, and has the unique
advantage of allowing a therapeutic trial
prior to permanent stimulator implantation.
GRADE B
Injectable biomaterials
• Multiple agents
• Technique
–Submucosal
–Intersphincteric
• Limited data
–Small case series
–Limited follow-up
• Initial improvement 40-60% [level 3]
–? Results deteriorate with time
Recommendation
• Most series of injectable biomaterials
report reasonable short-term success
rates. However, the optimal injectable
bulking agent and the technique for its
insertion have not been established.
GRADE C
Pediatric fecal incontinence
• Anorectal malformation,
Hirschsprung’s disease, neurologic
disorders, overflow
• Treatment options
–Bowel regimen
–Malone antegrade continent enema (ACE)
[level 3]
–Muscle transposition [level 4]
–Colostomy [level 5]
Recommendation
• Varying treatment options
including bowel management,
Malone antegrade continent enema
(ACE), muscle transpostion and
colostomy. GRADE C
Colostomy
• Technique of last resort
–Restores control, not continence
–Improves quality of life [level 4]
–? Under-utilized
• Diversion proctitis
–25% proctectomy rate
Recommendation
• Colostomy provides restoration of a more normal
lifestyle and improves quality of life. Colostomy
should not be regarded as a treatment failure. An
end sigmoid colostomy alone, without proctectomy,
is recommended. Some patients who develop
significant symptoms from their retained rectal
stump may eventually require proctectomy as a
secondary procedure. GRADE C
Research Priorities
• Validation of severity score
• Standardization of outcome measures
• Role of evaluation in determining
optimal treatment
Research Priorities
• RCT’s
–Sphincteroplasty vs. biofeedback
–Sphincteroplasty vs. SNS
–Sphincteroplasty technique
–Injectable biomaterials vs. placebo
• Non-RCT’s
–Cost analysis (SNS)
–Decision analysis
