The authors' aim is to review the medical literature dealing with diagnostic and therapeutical problems, after observations in pregnancy because of acute appendicitis in 9 cases. Diagnosis is difficult because of the aspecificity and the alterations both of the site of symptoms and clinical manifestations, particularly during the last period of gestation. As there is an upward displacement of the viscus by the pregnant uterine. Notwithstanding the use of some not invasive methods, such as graded-compression sonography, the diagnosis is always effected by the clinical examination. Surgical treatment is always possible in the presence of acute appendicitis, as pregnancy isn't a reason for delay. The maternal mortality is at a zero level, the fetal one varies from 2% to 43% in cases of perforated appendicitis.
