Structures pelvic pain evaluation with differential diagnosis and endometriosis assessment. Use when evaluating chronic pelvic pain, assessing for endometriosis, or managing pelvic pain workup.
Structures pelvic pain evaluation with systematic differential diagnosis, endometriosis assessment per ASRM staging, and multimodal management per ACOG Practice Bulletin No. 218.
Why This Skill Exists
Chronic pelvic pain (CPP) — defined as non-cyclic pain in the pelvis lasting ≥ 6 months — affects 15–20% of women aged 18–50 and accounts for 10% of outpatient gynecologic visits and 40% of diagnostic laparoscopies. The differential diagnosis spans gynecologic, urologic, gastrointestinal, musculoskeletal, and neurologic etiologies, making systematic evaluation essential. Endometriosis, the most common gynecologic cause, affects an estimated 10% of reproductive-age women but has an average diagnostic delay of 7–10 years.
ACOG Practice Bulletin No. 218 (Chronic Pelvic Pain) emphasizes a structured, multidisciplinary approach. This skill ensures that each organ system is evaluated, red flags are identified, and management follows evidence-based pathways rather than proceeding directly to surgery.
Checkpoint A: Pre-Draft Intake (Mandatory)
Pain characterization — location, quality, severity (0–10 NRS), duration, temporal pattern (cyclic vs. non-cyclic, relation to menses)? (Default: from structured pain history)
相关技能
Associated symptoms — dysmenorrhea, dyspareunia (superficial vs. deep), dyschezia, dysuria, bowel changes, bloating? (Default: from ROS)
Menstrual history — cycle length, regularity, HMB, AUB? (Default: from menstrual calendar)
Obstetric and surgical history — prior pregnancies, cesarean sections, laparoscopy, appendectomy, prior pelvic surgery? (Default: from history)
GI and urologic symptoms — IBS criteria (Rome IV), IC/BPS symptoms, recurrent UTI, hematuria? (Default: from symptom questionnaire)
Psychosocial assessment — depression, anxiety, history of physical or sexual abuse, catastrophizing? (Default: use PHQ-9 and GAD-7)
Psychosocial screening performed (PHQ-9, GAD-7, abuse history)
ASRM staging documented if laparoscopy performed
Management plan includes at least 2 modalities (hormonal, PT, psychological, analgesic)
Red flags screened and documented
Follow-up plan with reassessment timeline documented
Opioid use assessed and alternatives prioritized
Guidelines
CPP is multifactorial in most patients — assume overlapping etiologies until proven otherwise. Single-cause thinking leads to missed diagnoses and failed treatments.
Pelvic floor examination is mandatory — pelvic floor myalgia is present in up to 85% of CPP patients and is frequently the primary pain generator, yet is the most commonly missed diagnosis.
Surgery is not first-line — empiric hormonal therapy, physical therapy, and pain management should be trialed before diagnostic laparoscopy in most cases.
Endometriosis stage does not predict pain — a patient with Stage I may have debilitating pain; do not dismiss symptoms based on minimal surgical findings.
Screen for IBS and IC/BPS — these conditions co-occur with endometriosis in 30–50% of cases and require independent treatment.
Avoid chronic opioids — CPP is a chronic condition; opioids worsen long-term outcomes through hyperalgesia, dependence, and hormonal disruption.
Address the psychosocial dimension — trauma history, depression, and catastrophizing are not "causing" the pain but amplify it through central sensitization; addressing them improves outcomes.
Document the multidisciplinary plan — include gynecology, pelvic floor PT, pain psychology, and gastroenterology/urology as applicable.
