Chronic pelvic pain: the multifactorial biopsychosocial model, structured assessment & multidisciplinary management
Also known as Chronic pelvic pain · CPP · Pelvic pain syndrome · Multifactorial pelvic pain · Biopsychosocial pelvic pain · Pelvic pain clinic model
Exam-exhaustive FRANZCOG fellowship topic on chronic pelvic pain: the 6-month definition, the multifactorial biopsychosocial model (gynaecological, urological, gastrointestinal, musculoskeletal, psychological), the structured assessment of every system, the multidisciplinary stepped-care management, the role of laparoscopy, the evidence that LUNA is not effective, and the chronic-pelvic-pain clinic model. RCOG Green-top 41 anchored, ESHRE endometriosis guidance and the SPIRIT trials carried. RANZCOG-primary, globally tagged to MRCOG, ABOG, FRCSC and MRCPI.

Red flags
- A new or progressive pelvic mass, postmenopausal bleeding, weight loss or severe progressive dyspareunia — exclude ovarian, endometrial or colorectal malignancy before attributing pain to chronic pelvic pain
- Acute severe pain, fever, peritonism or syncope — exclude ectopic pregnancy, torsion, tubo-ovarian abscess or acute pelvic inflammatory disease
- Persistent postcoital bleeding, intermenstrual bleeding or offensive discharge — a focal lesion or malignancy is on the board; investigate, do not reassure
- Suicidal ideation or severe psychiatric comorbidity in a woman with chronic pelvic pain — escalate to mental health assessment now
- A woman whose pain escalates after multiple surgeries or who is on escalating opioids — central sensitisation and opioid-induced hyperalgesia are likely; rethink the plan
- A 'normal laparoscopy' does not make the pain imaginary — chronic pelvic pain without visible pathology is a recognised entity
A woman has sat in your clinic for forty minutes describing seven years of pelvic pain that no scan, no laparoscopy and no opioid has fixed. She has a folder of normal results and is starting to despair. Your job is not to find the single lesion she is missing — it is to reframe chronic pelvic pain as a multifactorial condition, assess every system, validate her experience, and build a multidisciplinary plan. The 6-month definition, the biopsychosocial model and the chronic-pelvic-pain clinic are the three ideas an examiner wants you to defend.[1][2]
Overview and definition
Chronic pelvic pain (CPP) is a symptom, not a disease. The standard definition is non-cyclic pain localised to the pelvis, the anterior abdominal wall at or below the umbilicus, the lumbosacral back or the buttocks, present for at least six months, of sufficient severity to cause functional disability or to warrant medical care.[1][15]
The 6-month threshold is the bedrock of the definition. Below it, you are dealing with acute or subacute pelvic pain; above it, the management paradigm shifts to a chronic-disease, biopsychosocial framework. Cyclical pain (worse with menses) points to a hormonally driven gynaecological cause such as endometriosis or adenomyosis; non-cyclical pain broadens the differential to every pelvic organ system.[7][9]
Why this matters — the burden in numbers
