Acute appendicitis during pregnancy presents diagnostic challenges. Outcomes were worst in the second trimester, with higher fetal wastage, though maternal risks remained consistent.

Area of Science:

  • Obstetrics and Gynecology
  • Surgical Gastroenterology

Background:

  • Appendicitis is a frequent cause of acute abdominal surgery in pregnant individuals.
  • Maternal and fetal complications associated with appendicitis in pregnancy are recognized.
  • Diagnostic and therapeutic challenges persist in managing pregnancy-related appendicitis.

Purpose of the Study:

  • To review maternal and fetal outcomes of appendectomies performed during pregnancy.
  • To identify trimester-specific complications and risks associated with appendicitis during gestation.

Main Methods:

  • Retrospective review of 38 obstetric cases undergoing appendectomy between 1986 and 1993.
  • Analysis of confirmed appendicitis cases based on laparotomy and histopathology.
  • Stratification of outcomes by trimester of pregnancy and postpartum period.

Main Results:

  • Acute appendicitis was confirmed in 31 of 38 cases, occurring across all trimesters and postpartum.
  • Complications included miscarriages (first trimester), abortions and preterm deliveries (second trimester).
  • The second trimester showed the highest fetal wastage rate; the third trimester/postpartum group had the highest incidence of perforated appendices.

Conclusions:

  • Appendicitis during pregnancy requires careful management due to potential maternal and fetal risks.
  • Second-trimester appendicitis poses the greatest risk to fetal survival.
  • While maternal morbidity was similar across trimesters, advanced appendicitis was more common in the third trimester/postpartum period.
