Clinical Case
Chronic Pelvic Pain
Patient Presentation
A 24-year old woman presents to you as a
self-referral for pelvic pain. She describes
a four-year history of intermittent lower
abdominal and pelvic pain that is now
constant in nature. The pain is always
present, sometimes sharper in the left
lower quadrant and not related to
menses.
Patient Presentation
She has occasional nausea and is sometimes
constipated. Nothing makes the pain better or
worse. Over the years, she has used
acetaminophen and ibuprofen, and has not
found any relief. She began her menses at age
13 and they have come on a regular monthly
basis. She experiences some premenstrual
bloating and has cramps with her periods, and
reports discomfort at other times of the month.
Patient Presentation
She had a trial of oral contraceptives and
then a subsequent laparoscopy by a prior
gynecologist. She was told that everything
looked normal. She is otherwise a healthy
non-smoker, but reports that this pain is
making her life miserable.
Patient Presentation
She has a bachelor’s degree from a local
college, works as computer processor
and lives at home with her parents. She
has never been sexually active. Upon
further questioning, she reports that her
oldest brother sexually abused her as a
child.
Patient Presentation
Physical exam
Somewhat flattened affect, but smiles occasionally. 5
feet 4 inches; 142 pounds. Trapezius and paraspinous
muscles tender on palpation. No costovertebral angle
tenderness. Abdomen is soft with 2 well-healed
pelviscopy incisions. There is no rebound or guarding or
mass. Tenderness is elicited with deep palpation of the
lower quadrants. External genitalia, vagina and cervix
are normal. Uterus is mid-position, mobile and the
adnexa are mildly tender. The rectal vault is palpably
normal with soft stool that is heme negative.
Differential diagnosis of chronic
pelvic pain
Gynecologic origin
Gastrointestinal disorders
Urinary problems
Musculoskeletal disease
Pain processing disorders
Psychiatric and psychological
Management Plan
The patient was counseled about the multiple possible causes of
chronic pelvic pain. The provider was empathic and sensitive in
regards to this challenging problem. A plan of care was devised
jointly and she was scheduled for a follow-up. The patient’s
previous records and operative report was obtained and
reviewed. On a subsequent visit, the patient did note that the
pain worsens when her older brother returns home for family
holidays. She reports that she has never mentioned this to the
therapist that she has recently started seeing. A trial of low dose
tricyclic antidepressants was initiated which helped the patient
with sleeping, but did not make the pain go away. The patient
continued to follow up at regularly scheduled intervals with her
gynecologist and therapist, and had less emergency room visits.
Teaching points
Chronic pelvic pain can be defined as cyclic pain
of 6 months duration or non-cyclic pain of 3
months duration and the pain interferes with
normal activities. The problem of chronic pelvic
pain is under-recognized. It may affect 15% to
24% of American women and accounts for a
large proportion of office visit time and many
invasive surgical procedures.
Teaching points
Chronic pelvic pain can be derived from a variety
of sources, including gynecologic,
gastrointestinal, rheumatologic,
musculoskeletal, urologic or psychiatric. It can
be difficult to diagnose the etiology and can be
challenging to treat. The health care provider
must perform a thorough history and physical
exam, which are often much more valuable in
making a diagnosis than any laboratory or
radiologic tests.
Teaching points
Patients present to different specialists based on their
belief of what is causing the pain. Gastrointestinal
diseases may cause symptoms such as nausea,
vomiting, bloating or changes in bowel habits. Urinary
tract disorders my cause dysuria, urgency or vague
pelvic discomfort. Patients need to be asked about
fatigue, sleep disturbances, or mood disorders and
fibromyalgia and depression considered. Patients also
need to be queried about physical and sexual abuse, or
any history of substance abuse. Musculoskeletal
disorders can be determined by a thorough motor and
sensory examination, with attention to the back, hips
and legs.
Teaching points
Possible gynecologic causes of chronic pelvic pain include
endometriosis, adenomyosis, chronic pelvic infection or
adhesions. A normal laparoscopy does not completely
rule out endometriosis, as the changes can be subtle
and occasionally missed. Providers can consider an
empiric trial of oral contraceptives or GnRH agonists
after non-gynecologic causes have been ruled out.
Some providers recommend a trial of antibiotics or nonsteroidal anti-inflammatories for potential infectious
causes. In the case of depression, whether overt or
covert, antidepressants should be initiated.
Teaching points
Even when the etiology is determined,
chronic pelvic pain can be difficult to treat.
The patient may need to be seen
regularly and provided with much support.
Co-management with a psychologist,
social worker or therapist may be helpful.
