Indications for Laparoscopic Surgery in Pregnancy
Laparoscopy during pregnancy is typically performed when the benefits outweigh the risks. Common indications include:
Acute Abdomen and Surgical Emergencies
Appendicitis: The most common non-obstetric surgical emergency requiring intervention.
Cholecystitis: Gallbladder disease, including symptomatic gallstones, which may necessitate laparoscopic cholecystectomy.
Ovarian Torsion: Prompt diagnosis and detorsion are essential to preserve ovarian function.
Ruptured Ovarian Cysts: Persistent pain or hemorrhage may require laparoscopic intervention.
Ectopic Pregnancy
Tubal Ectopic Pregnancy: Laparoscopic salpingectomy or salpingostomy is the treatment of choice for ruptured or non-viable ectopic pregnancies.
Heterotopic Pregnancy: Simultaneous intrauterine and extrauterine pregnancies may require laparoscopic management.
Pelvic Masses and Adnexal Pathologies
Laparoscopic removal of large ovarian cysts or suspicious masses to prevent complications such as torsion or rupture.
Myomectomy for Fibroids
Select cases of symptomatic fibroids causing significant pain or obstructive effects may be considered for laparoscopic intervention.
Safety Considerations and Surgical Modifications
Performing laparoscopic surgery in pregnant patients requires special precautions to minimize risks to both the mother and fetus:
1. Optimal Patient Positioning
Left lateral tilt to avoid compression of the inferior vena cava, reducing the risk of maternal hypotension and fetal distress.
Avoid Trendelenburg positioning for prolonged periods to prevent respiratory compromise.
2. Trocar Placement and Pneumoperitoneum Management
Modified trocar placement to accommodate the enlarged uterus, often using an upper abdominal approach.
Low-pressure pneumoperitoneum (8–12 mmHg) to minimize intra-abdominal pressure effects on uteroplacental circulation.
3. Anesthesia Considerations
Close fetal heart rate monitoring throughout the procedure.
Avoidance of hypoxia, hypercapnia, and acidosis, which could negatively impact fetal outcomes.
4. Minimizing Operative Time
Shorter surgical durations are preferred to reduce fetal exposure to anesthetic agents.
Use of advanced energy devices (harmonic scalpel, Ligasure) to ensure efficient and precise dissection.
Advantages of Laparoscopy Over Open Surgery in Pregnancy
Laparoscopic procedures offer significant benefits over traditional open surgery, including:
Smaller incisions leading to reduced postoperative pain.
Lower risk of wound infections and hernias.
Faster recovery with reduced hospital stays.
Minimal uterine manipulation, decreasing preterm labor risks.
Improved visualization with high-definition cameras, allowing precise dissection.
Potential Risks and Complications
Despite its advantages, laparoscopic surgery in pregnancy carries potential risks, including:
Fetal distress due to maternal hypotension or hypoxia.
Inadvertent uterine injury if port placement is not carefully planned.
Preterm labor or pregnancy loss in rare cases.
Conclusion
Laparoscopy has emerged as a safe and effective option for managing various surgical conditions during pregnancy, provided that the procedure is performed with necessary modifications and precautions. With careful patient selection, experienced surgical teams, and adherence to best practices, laparoscopic surgery can offer better maternal outcomes with minimal fetal risks. As advancements in robotic-assisted laparoscopic surgery continue, the role of minimally invasive surgery during pregnancy will likely expand further.
