[Appendicitis and pregnancy: 21 cases].

OBJECTIVE

Describe the epidemiological, diagnostic and therapeutic features of acute appendicitis in pregnant women.

MATERIAL AND

METHODS

Retrospective analysis of a series of 21 cases of appendicitis in pregnant women who underwent surgery between January 1997 and June 2001.

RESULTS

The association of acute appendicitis with pregnancy was noted in 0.2% of the pregnant women. Ten patients were in the first trimester of pregnancy, ten in the second and one in the third. Abdominal pain was noted in all patients. The localization varied with gestational age. Abdominal ultrasound contributed to the diagnosis in twenty patients who underwent the examination. Diagnoses retained were: acute uncomplicated appendicitis (n=18), acute appendicitis with focal induration (n=1) and acute diffuse peritonitis (n=2). Appendectomy was performed in all cases. Intensive care, peritoneal cleaning and drainage were associated in cases with appendicitis. In cases with focal induration, medical treatment was followed by appendectomy performed after delivery. Tocolysis was instituted in all cases. Twelve pregnancies continued to delivery: one fetal death, one premature delivery and ten term deliveries of live infants.

CONCLUSION

Pregnancy makes it difficult to confirm the diagnosis of appendicitis. Appendectomy should be performed in patients presenting a highly suggestive clinical and ultrasonographic picture, preferably by laparoscopy in order to avoid more severe complications which could be life-threatening for the mother or infant.
