CHRONIC PELVIC PAIN
Bruce G. Bateman, MD
2
Chronic Pelvic Pain
  • Scope and Cost
  • Back pain 4.1
  • Chronic pelvic pain 3.8
  • Asthma 3.7
  • Migraine 2.1
  • Direct and Indirect Costs to U.S.
  • Healthcare system 2 billion/year
  • Organ System Distribution
  • Gastrointestinal 38
  • Urinary 31
  • Gynecologic 20

3
CPPGeneral Associations/Demographics
  • No association with race, ethnicity,
    socioeconomic status
  • Tends to occur with higher frequency in
    reproductive age women
  • Higher prevalence in separated or divorced women

Obstet Gynecol 1996
4
The Importance of Placebo Effect in Pain
Treatment/Research
  • Review of placebo effect studies
  • Placebo effect frequency varies and is often gt30
  • Placebo effect occurs with surgical and medical
    therapy
  • A placebo effect prone personality was not
    identified

Turner Et Al Jama, 1994
5
Echelons of Data
  • Randomized controlled trials
  • Controlled trials without randomization, case
    controlled, multiple series
  • Opinions of authorities or expert committees

mistakes

7
Scope of Pelvic Pain Differential Diagnosis
  • ACOG practice bulletin 2004 lists 68 diagnoses
  • Diagnoses are organized based data levels
  • I, II, III
  • There are 28 level I disorders

8
GYN
9
CPP GYN Differential Diagnosis Level I Data
  • Endometriosis
  • GYN Malignancy
  • Pelvic Congestion Syndrome
  • Ovarian Remnant Syndrome
  • Pelvic Inflammatory Disease
  • TB Salpingitis

Endometriosis
12
Does Response to Hormonal Therapy Predict
Presence or Absence of Endometriosis?
Jenkins Human Reprod 2008
  • 104 patients treated for 3 months of hormonal
    therapy for pelvic pain
  • 57 failed to respond. 47 responded.
  • Laparoscopy findings
  • 67 of responders had endo
  • 68 of non-responders had endo

Visible and Non-Visible Endometriosis and
Laparoscopy in Fertile and Infertile Women and
Patients with Pelvic Pain
Balasch Human Reprod 1996
  • N100
  • Endometriosis present
  • 50 - Infertility
  • 44 - Pelvic Pain
  • 43 - Normal Fertile
  • Normal appearing uterosacral ligament
  • Biopsy
  • in 11 visible endometriosis group
  • in 6 no visible endometriosis

16
Surgical Treatment of Endometriosis
  • Pain relief after conservative surgery widely
    variable approximately 50 ¹
  • Recurrent pain after conservative surgery tends
    to be refractory to further surgery ¹
  • Uterosacral and presacral nerve ablation
    procedures lack level I data to support
    usefulness ²
  • Hysterectomy for pain/endometriosis has 15
    incidence of recurrent pain within one year ³

¹ Olive 2002 ² Vercellini 1991
³ Vercellini 2000
17
Cost of Treatment 6 Month Course
  • Lupron 4000
  • Mirena IUD 700
  • Oral Contraceptives 500
  • Depo Provera 348

18
Randomized Trial of Levonorgestrel IUD and GnRH
Analogue ForEndometriosis and Pelvic Pain
Petta Hum Reprod 2005
  • 82 patients
  • Daily pain diary
  • 6 month treatment
  • 85 IUD group pain relief
  • 83 GnRH analogue pain relief
  • Trend to faster pain relief in Stage III and IV
    disease

19
Aromatase Inhibitors for Treatment of
Endometriosis
  • Endometriosis implants grow in response to
    estrogen
  • Endometriosis implants have significant aromatase
    activity ¹
  • Aromatase acts at the last step in estrogen
    synthesis
  • Type II aromatase inhibitors cause competitive
    inhibition
  • Anastrozole
  • Letrozole

Endometriosis Summary Points
  • Perform laparoscopy early
  • Recognize endometriomas on ultrasound
  • Consider Mirena IUD for medical therapy
  • Aromatase inhibitors/oral contraceptives for pain
  • When doing extrapative surgery - remember the
    source of estrogen

Pelvic Vascular Congestion Syndrome
  • First described 1949 H.C. Taylor in Amer J
    Ob/Gyn attributed to stress
  • Symptoms
  • Pelvic pain
  • Shifting location
  • Deep dyspareunia
  • PC pain
  • ? pain by standing
  • Normal peripheral hormone levels ¹
  • Findings

26
Incompetent Ovarian VeinsCommon CT Findings
Rozenblit 2001
  • 34 female renal donors
  • CT scans
  • Dilated, incompetent veins present in 47 of
    asymptomatic women

27
Ovarian Veins MRI Findings in Asymptomatic
Population
Nascimento 2001
  • 22 female renal donors
  • Asymptomatic
  • 38 had passive reflux from left renal vein into
    gonadal vein with significant dilation

28
Ovarian Vein Embolization for Treatment of Pelvic
Congestion
Maleux 2000
  • 41 women, mean age 38 years
  • 32 underwent unilateral ovarian vein embolization
  • 9 bilateral embolization
  • Results (mean follow up 20 months)
  • 9 variable pain relief
  • 58 total pain relief

29
Treatment of Pelvic Congestion
  • 47 patients with pure pelvic congestion
    syndrome
  • Randomized to 6 months treatment
  • Goserelin 3.75 mgm/m
  • v
  • Medroxyprogesterone 30 mgm/d
  • Follow up at 12 months

    and venography scores

Soysal 2001

Gastrointestinal
31
CPP Gastrointestinal Differential Diagnosis
  • Colon cancer
  • Constipation
  • Inflammatory bowel disease
  • Irritable bowel syndrome

ACOG Practice Bulletin 2004
32
Irritable Bowel Syndrome
  • 12 weeks of 2 of 3 of these pain associations
    (within 12 months)
  • Relieved by defecation
  • Onset associated with change in frequency of
    stool
  • Onset associated with change in stool form

Rome II Criteria
33
IBS
  • Prevalence greater in women
  • First presentation to physician gt between ages
    30-50
  • Prevalence is similar in whites and blacks may
    be lower in hispanics

AGA Technical Review 2002
34
What Do Patients with Irritable Bowel Disease
Dream About?
  • Significantly more patients with irritable bowel
    syndrome (18) and inflammatory bowel disease
    (22) vs controls (3) dreamt their bowels

Dig. Liver. DIS 2002
35
Pathophsysiocology IBS
  • Motility although transit is accelerated in
    diarrhea and slowed in constipation there is no
    consensus on motility abnormalities in patients
    with IBS
  • Viseral Hypersensitivity IBS patients have pain
    at lower lumenal bowel volumes and pressures
    than uneffect patients
  • Inflammation varied gut immune response
  • CNS Modulation CNS modulates motility,
    secretion, immune function, and blood flow

AGA Technical Review 2002
36
IBS Pathophysiology
  • Psychogenic stress exacerbates GI symptoms
  • Psychiatric comorbidity is common among IBS
    patients
  • Psychosocial factors affect clinical outcome
  • Psychosocial factors affect which patients
    consult physicians

AGA Technical Review 2002
37
GI Evaluation
  • If alarm signs are absent, evaluation may
    include physical exam only with a trial of
    treatment
  • Signs that drive testing
  • Short symptom duration with rapid progression
  • Demographics age gt 50
  • Family history positive for cancer or
    inflammatory bowel disease
  • Absence of clear psychosocial issues
  • Other evaluation possibilities
  • CBC, Chemistries, Sed Rate, TSH
  • Stool for ova and parasites
  • Colonoscopy
  • Bowel biopsy
  • Bowel radiographics

AGA Technical Bulletin 2002
38
IBS - Treatment
  • Diet
  • Patients often attribute symptoms to specific
    foods
  • However, there are no food types that uniformly
    cause symptoms in IBS
  • Drug therapy for symptoms
  • Pain
  • antispasodics (smooth muscle relaxants)
    dicyclomine
  • peppermint oil
  • Psychological treatment useful if
  • Awareness that stress increased symptoms at least
    mild anxiety/ depression
  • Main symptom is pain/diarrhea

39
IBS Treatment - Reviews
  • Bulking agents, antispasmodics and
    antidepressants for treatment of IBS
  • 16 studies reviewed
  • Conclusions
  • Antispasmodics may be effective to decrease pain
    from IBS
  • No evidence bulking agents are effective
    treatment
  • No evidence antidepressants are effective
    treatment

Cochran Review Quartero 2005

Herbal Medications for Treatment of IBS
  • Studies are of generally poor quality
  • Herbal medications are promising
  • It is premature to recommend herbal treatment
    for IBS
