Ch ronic Pelvic Pain

1. Chronic Pelvic Pain

2. Chronic Pelvic Pain Definition Chronic Pelvic Pain (CPP) is pain of apparent pelvic origin that has been present most of the time for the past six months

3. Chronic Pelvic Pain Definition • Difficult to diagnose Frustration for patient and physician • Difficult to treat • Difficult to cure

4. Chronic Pelvic Pain Incidence • Affects 15-20% of women of reproductive age • Accounts for 20% of all laparoscopies • Accounts for 12-16% of all hysterectomies • Associated medical costs of $3 billion annually

5. Chronic Pelvic Pain Demographics • Demographics of age, race, ethnicity, education, and socioeconomic status do not differ between those with and without chronic pelvic pain • Higher incidence in single, separated or divorced women • 40-50% of women have a history of abuse

6. Psychological Gastrointestinal Etiology Urological Gynecological Musculoskeletal

7. Chronic Pelvic Pain Etiology: United Kingdom Primary Care Database • 25-50% of women had more than one diagnosis • Severity and consistency of pain increased with multisystem symptoms • Most common diagnoses: • endometriosis • adhesive disease • irritable bowel syndrome • interstitial cystitis Diagnosis Distribution Gastrointestinal Urinary Gynecological 37.7% 30.8% 20.2%

8. Chronic Pelvic Pain Diagnosis Obtaining a COMPLETE and DETAILED HISTORY is the most important key to formulating a diagnosis

9. Chronic Pelvic Pain Diagnosis: Obtaining the History • Duration of Pain • Nature of the Pain • Sharp, stabbing, throbbing, aching, dull? • Specific Location of Pain • Associated with radiation to other areas? • Modifying Factors • Things that make worse or better? • Timing of the Pain • Intermittent or constant? • Temporal relationship with menses? • Temporal relationship with intercourse? • Predictable or spontaneous onset? • Detailed medical and surgical history • Specifically abdominal, pelvic, back surgery

10. Chronic Pelvic Pain Diagnosis: Obtaining the History • Use the REVIEW OF SYSTEMS • to obtain focused, detailed history of organ systems involved in the differential diagnosis

11. Chronic Pelvic Pain Diagnosis: Obtaining the History Gynecological Review of Systems • Associated with menses? • Association with sexual activity? (Be specific) • New sexual partner and/or practices? • Symptoms of vaginal dryness or atrophy? • Other changes with menses? • Use of contraception? • Detailed childbirth history? • History of pelvic infections? • History of gynecological surgeries or other problems?

12. Chronic Pelvic Pain Diagnosis: Obtaining the History Gastrointestinal Review of Systems • Regularity of bowel movements? • Diarrhea/ constipation/ flatus? • Relief with defecation? • History of hemorrhoids/ fissures/ polyps? • Blood in stools, melena, mucous? • Nausea, emesis or change in appetite? • Abdominal bloating? • Weight loss?

16. Chronic Pelvic Pain Diagnosis: The Physical Exam Evaluate each area individually • Abdomen • Anterior abdominal wall • Pelvic Floor Muscles • Vulva • Vagina • Urethra • Cervix • Viscera – uterus, adnexa, bladder • Rectum • Rectovaginal septum • Coccyx • Lower Back/Spine • Posture and gait A bimanual exam alone is NOT sufficient for evaluation

47.
