Obstetrical outcomes following laparoscopy during pregnancy: a retrospective case–control study

Purpose: To evaluate pregnancy outcome of patients who undergo laparoscopy during pregnancy. Methods: A retrospective case–control study, conducted in a single university-affiliated tertiary care medical center, comparing pregnancy outcomes of women who underwent laparoscopy during pregnancy to women without operations during pregnancy. The study group (n = 232) included all pregnant women who underwent a single laparoscopic surgery during pregnancy (4–28 weeks of gestation) which culminated in delivery between 2006 and 2017; this study group was matched to a control group (n = 463) without surgical intervention during pregnancy, in a 2:1 ratio by maternal age, parity, and multiple gestation. Results: The main pregnancy outcomes included preterm birth, cesarean section, small for gestational age (≤ 10 percentile), and Apgar score of less than 7 in 5 min. Laparoscopy during pregnancy was associated with an increased risk for cesarean section (32.3% vs. 24.6%, adjusted OR = 1.9, CI 1.2–3.1, p = 0.011). We found no difference between the groups with regard to other outcomes, including rates of preterm birth (12.1% vs. 10.4%, adjusted OR = 1.3, CI 0.64–2.72, p = 0.451). In a subgroup analysis of the study group, various perioperative parameters such as operation duration, hospitalization length, and others, did not correlate with adverse pregnancy outcome. Conclusions: Laparoscopy during pregnancy may be associated with an increased rate of cesarean section. We did not find an increase in any other pregnancy or neonatal complication. Different perioperative parameters did not appear to predict adverse pregnancy outcome.
