Acute appendicitis in pregnancy: 50 case series, maternal and neonatal outcomes

During pregnancy, the most common indication for non-obstetric surgery in acute abdomen is appendicitis. In pregnancy, appendicitis may be confused with pregnancy-related pathologies and may cause a delay in diagnosis or unnecessary surgery. The present study aims to evaluate the maternal and neonatal outcomes of patients undergoing appendectomy during pregnancy.

This study was designed retrospectively between 2011-2017. Appendicitis detection rates, admission and laboratory features, operation results and obstetric results were evaluated in pregnant women who underwent surgery for a preliminary diagnosis of acute appendicitis.

The findings showed that 2593 patients underwent an appendectomy, 1154 of them were women and 50 of them were pregnant. Negative laparotomy was detected in 12 (16%) patients. Six (12%) of these 50 patients had a laparoscopic appendectomy and 44 (88%) had an appendectomy with laparotomy. The mean time to operation after admission to hospital was 10.5±11 hours. No maternal mortality was observed. Preterm labor occurred in four (8%) patients. Two patients (4%) were in the second trimester and two patients (4%) were in the third trimester. Two (4%) newborns born in the second trimester died postpartum. One of these newborns had multiple anomalies. Appendectomy was not characterized by an increased risk of perinatal mortality.

Delay in the diagnosis and surgery of acute appendicitis during pregnancy may increase the risk of perinatal mortality and should not be delayed in diagnosis and surgery in pregnancy.
