Retrospective Evaluation of the Effect of Age and Obstetric History on Tubal Location in Tubal Ectopic Pregnancies

Objective: Ectopic pregnancy is one of the most common early complications of pregnancy. It can cause severe morbidity and even mortality. We aimed to determine the relationship between maternal age, parity, and side of tubal ectopic pregnancy (TEP) in cases with a TEP that underwent surgery.
Methods: The present study included 241 patients who were diagnosed with TEP. The side of TEP was determined by laparotomy or laparoscopy. The patients were stratified according to their age as 20-24 years old, 25-29 years old, 30-34 years old, 35-39 years old and ≥40 years. Besides, the patients were subdivided based on parity as nullipara, primipara, and multipara.
Results: The tubal ectopic pregnancies were right-sided in 69.3% and left-sided in 30.7%. Right-sided localization was significantly more common than leftsided localization (p<0.001). When localization of tubal ectopic pregnancies was assessed according to age, it was found that tubal ectopic pregnancies in age groups of 30-34, 35-39, and ≥40 years were more commonly localized at the right tuba (p<0.001). In age groups of 20-24 and 25-29 years, no significant difference was found in ectopic tubal pregnancy localization.
Conclusion: When TEP localization was assessed according to parity, it was found that tubal ectopic pregnancies were more commonly localized at the right tuba in primary and multipara groups.
