What is the best approach to manage cholecystitis (inflammation of the gallbladder) in a pregnant patient with pain?

Management of Cholecystitis in a 26-Year-Old Pregnant Patient

Laparoscopic cholecystectomy is the recommended treatment for cholecystitis during pregnancy and should be performed, ideally during the second trimester, rather than pursuing conservative management. 1

Initial Management Approach

While initial stabilization with IV hydration and symptom control is appropriate 2, definitive surgical intervention should be planned rather than relying on prolonged conservative management. The evidence strongly favors early surgical intervention:

• Conservative management fails in 60% of pregnant patients, leading to recurrent biliary symptoms and multiple hospitalizations 2
• Patients managed conservatively have significantly higher rates of emergency department visits and readmissions compared to those who undergo cholecystectomy 3
• Conservative treatment is associated with higher rates of spontaneous abortion, threatened abortion, and premature birth compared to surgical intervention 2

Surgical Timing and Approach

The second trimester is optimal for laparoscopic cholecystectomy 1, 4, 2:

• First trimester carries higher risk of miscarriage and anesthetic toxicity 2
• Third trimester presents technical difficulties due to uterine size and higher risk of preterm labor 4, 2
• However, laparoscopic cholecystectomy is safe regardless of trimester if clinically indicated 1

Laparoscopic approach is superior to open cholecystectomy 2:

• Maternal complications: 3.5% vs 8.2% for open surgery 2
• Fetal complications: 3.9% vs 12.0% for open surgery 2
• Shorter hospital stay and faster recovery 5

Surgical Technique Considerations

Key technical modifications for pregnancy 4:

• Use low intra-abdominal pressure (10-13 mmHg) to minimize maternal and fetal complications 4
• Employ open introduction technique to avoid trocar injury to the uterus 4
• Limit procedure duration to 90-120 minutes 4
• Use bipolar cautery with grounding pad placed on leg, right shoulder, or arm to prevent electrical current through amniotic fluid 4

Anesthetic Management

Regional anesthesia is preferred to minimize fetal exposure to anesthetic medications 4:

• Combined spinal-epidural or dural puncture epidural may provide more reliable anesthesia 4
• If general anesthesia is used, propofol, fentanyl, and midazolam are safe alternatives 4
• Aspiration prophylaxis is essential due to increased risk of gastroesophageal reflux in pregnancy 4

Positioning and Monitoring

Critical perioperative considerations 4:

• After 20 weeks gestation, avoid supine positioning to prevent supine hypotension syndrome 4
• Position patient in left lateral tilt or left lateral decubitus to minimize inferior vena cava compression 4
• Maintain continuous maternal hemodynamic monitoring and normal blood pressure to ensure adequate placental perfusion 4
• Implement fetal heart rate monitoring based on gestational age 4

Management of Complications

If choledocholithiasis or cholangitis is suspected 1, 2:

• Non-contrast MRCP can be performed safely for diagnosis 2
• ERCP may be performed for urgent indications (choledocholithiasis, cholangitis, gallstone pancreatitis), ideally in the second trimester 1, 2
• Be aware that pregnancy increases post-ERCP pancreatitis risk (12% vs 5% in non-pregnant patients) 2
• Multidisciplinary team involvement is essential for ERCP procedures 2

Alternative Management (Bridging Therapy Only)

Percutaneous cholecystostomy should only be considered as temporary bridging therapy in specific circumstances 2:

• Hemodynamically unstable patients
• First trimester cases to bridge to second trimester
• Late third trimester cases to bridge to postpartum period
• Note: This approach is associated with longer hospital stays and should not replace definitive surgical management 6

Common Pitfalls to Avoid

• Do not rely on conservative management as the primary treatment strategy—it leads to recurrent symptoms in 60% of cases 2
• Do not delay surgery until postpartum unless presenting in late third trimester, as this increases maternal and fetal complications 2, 3
• Do not use leukocytosis alone for diagnosis, as it can be misleading in pregnancy 2
• Do not choose open cholecystectomy over laparoscopic approach unless specifically indicated, as it has significantly higher complication rates 2, 7
