Abstract

Background: Laparoscopic appendectomy (LA) is the standard treatment for acute appendicitis (AA) in general population. However, the safety of LA during pregnancy has remained a matter of debate. The purpose of this study was to compare surgical and obstetrical outcomes in pregnant women who underwent LA vs. open appendectomy (OA) for AA. We hypothesized that LA results in improved surgical and obstetric outcomes during pregnancy.

Methods: Using a nationwide claim-based database in Estonia, a retrospective review of all cases of pregnant women undergoing OA or LA for AA from 2010 to 2020 was performed. Patient characteristics, surgical and obstetrical outcomes were analyzed. Primary outcomes were preterm delivery, fetal loss and perinatal mortality. Secondary outcomes included operative time, hospital length of stay (HLOS) and 30-day postoperative complications.

Results: Overall, 102 patients were included of whom 68 (67%) underwent OA and 34 patients (33%) LA, respectively. Patients in LA cohort had a significantly shorter length of pregnancy in terms of gestational weeks when compared to OA cohort (12 weeks versus 17 weeks, p = 0.002). Most of the patients in their 3rd trimester pregnancy were subjected to OA. Operative time in LA cohort was shorter than in OA cohort (34 min. versus 44 min., p = 0.038). HLOS in LA cohort was shorter than in OA cohort (2.1 days versus 2.9 days, p = 0.016). There were no differences between OA and LA cohorts in terms of surgical complications or obstetrical outcomes.

Conclusions: Laparoscopic appendectomy for acute appendicitis was associated with a significantly shorter operative time and a shorter hospital length of stay while open and laparoscopic appendectomy cohorts experienced comparable obstetrical outcomes. Our findings support the laparoscopic approach for acute appendicitis in pregnancy.
