Are severe pelvic pains a month after a dilation and curettage (D&C) concerning and what could be the cause?

Severe Pelvic Pain One Month After D&C: Assessment and Management

Yes, severe pelvic pain one month after a D&C is concerning and warrants immediate evaluation, as severe pain at this timepoint is unusual and should prompt assessment for unrecognized complications including infection, retained products of conception, uterine perforation, or adhesion formation. 1

Most Likely Causes

Infectious Complications

• Endometritis or pelvic inflammatory disease is a leading concern, accounting for approximately 20% of acute pelvic pain cases following instrumentation or surgery 2
• Recent instrumentation (such as D&C) is a common iatrogenic cause of pelvic infection, which can manifest as tubo-ovarian abscess, endometritis, or peritonitis 2
• Isolated endometritis can also occur with cervical stenosis, which may develop post-procedure 2

Structural Complications

• Intrauterine adhesions (Asherman syndrome) can develop after D&C and cause significant pelvic pain 3
• Uterine perforation (if unrecognized at time of procedure) may present with delayed pain 4
• Retained products of conception can cause ongoing pain and may become infected 4

Chronic Pain Development

• Cesarean section has been associated with chronic pelvic pain (OR=3.7), and similar mechanisms may apply to other uterine procedures 5
• Pelvic adhesions develop in a significant proportion of patients after pelvic surgery and can cause chronic pain 5, 3

Immediate Diagnostic Approach

First-Line Imaging

• Transvaginal ultrasound is the primary diagnostic tool and should be performed first to evaluate for retained products, fluid collections, abscess formation, or other structural abnormalities 1, 4
• Ultrasound can assess endometrial thickness, identify intrauterine fluid or debris, and evaluate for adnexal pathology 4

Second-Line Imaging

• CT abdomen and pelvis with IV contrast should be considered if ultrasound is nondiagnostic or if there is concern for perforation, abscess, or other complications requiring urgent intervention 2
• CT is particularly useful when the clinical presentation is nonspecific or includes both gynecologic and nongynecologic possibilities 2

Clinical Red Flags Requiring Urgent Evaluation

• Fever or purulent vaginal discharge suggests infection requiring prompt treatment 1
• Hemodynamic instability (tachycardia, hypotension) requires immediate medical attention 1
• Severe, persistent pain that is worsening or not responding to analgesics 1

Pain Management Strategy

Multimodal Approach

• Acetaminophen (650 mg every 6 hours or 975 mg every 8 hours) as first-line analgesic 1
• Ibuprofen 600 mg every 6 hours for anti-inflammatory effect (if not contraindicated) 2
• Non-pharmacologic interventions including heat application and rest 1

Opioid Considerations

• Minimize opioid prescriptions and use only for severe pain not controlled by non-opioid analgesics 2, 1
• If opioids are necessary, prescribe short courses of low-dose formulations (e.g., 5-10 tablets of hydrocodone 5 mg) 2

Critical Management Principles

Do Not Dismiss Severe Pain

• Persistent severe pain should never be dismissed as normal following any gynecologic procedure and requires thorough evaluation 1
• Severe pain after procedures is unusual and should prompt evaluation for complications 2

Treatment Based on Etiology

• If infection is identified: Broad-spectrum antibiotics covering polymicrobial pelvic pathogens 2
• If retained products: May require repeat D&C or hysteroscopic removal 4
• If adhesions suspected: Consider referral for hysteroscopic evaluation and lysis 3
• If perforation identified: Surgical consultation for possible repair 4

Follow-Up Recommendations

• Serial evaluation may be necessary if initial workup is inconclusive 1
• Consider referral to gynecology for diagnostic laparoscopy if pain persists without clear etiology on imaging 3, 4
• Long-term management may require a biopsychosocial approach if pain becomes chronic, though identifying and treating the underlying cause is paramount 3

Common Pitfalls to Avoid

• Underestimating post-procedural complications: Recent instrumentation significantly increases infection risk 2
• Relying solely on imaging: Normal ultrasound does not exclude all pathology; clinical correlation is essential 4
• Overuse of opioids: Prioritize non-opioid analgesics and address the underlying cause rather than masking symptoms 2, 1
• Delayed evaluation: Waiting to see if pain resolves spontaneously can allow complications like infection or perforation to worsen 1
