EAES rapid guideline: systematic review, meta-analysis, GRADE assessment, and evidence-informed European recommendations on appendicitis in pregnancy.

BACKGROUND

Clinical practice recommendations for the management of acute appendicitis in pregnancy are lacking.

OBJECTIVE

To develop an evidence-informed, trustworthy guideline on the management of appendicitis in pregnancy. We aimed to address the questions of conservative or surgical management, and laparoscopic or open surgery for acute appendicitis.

METHODS

We performed a systematic review, meta-analysis, and evidence appraisal using the GRADE methodology. A European, multidisciplinary panel of surgeons, obstetricians/gynecologists, a midwife, and 3 patient representatives reached consensus through an evidence-to-decision framework and a Delphi process to formulate the recommendations. The project was developed in an online authoring and publication platform (MAGICapp).

RESULTS

Research evidence was of very low certainty. We recommend operative treatment over conservative management in pregnant patients with complicated appendicitis or appendicolith on imaging studies (strong recommendation). We suggest operative treatment over conservative management in pregnant patients with uncomplicated appendicitis and no appendicolith on imaging studies (weak recommendation). We suggest laparoscopic appendectomy in patients with acute appendicitis until the 20th week of gestation, or when the fundus of the uterus is below the level of the umbilicus; and laparoscopic or open appendectomy in patients with acute appendicitis beyond the 20th week of gestation, or when the fundus of the uterus is above the level of the umbilicus, depending on the preference and expertise of the surgeon.

CONCLUSION

Through a structured, evidence-informed approach, an interdisciplinary panel provides a strong recommendation to perform appendectomy for complicated appendicitis or appendicolith, and laparoscopic or open appendectomy beyond the 20th week, based on the surgeon's preference and expertise.
