The aim's study is to validate a therapeutic aid in women with a less active ectopic pregnancy. A prospective recrutement of 100 women will be performed in 16 different hospitals in France. The decision aid will be used and a questionnaire about its usefulness, comprehension and satisfaction will be given to women and doctors.

In less active ectopic pregnancy, two treatments are possible: a medical treatment using methotrexate or a surgical management.

A discret choice experiment study was performed to reveal women's preferences between these two options. In conclusion, calculated preferences are 47.5 and 52.5%, revealing a difficult choice for women. This study also lead to identify the main attributes important to make the choice. We were then able to create a therapeutic decision aid to help this shared decision.

This aid needs to be validated, following steps for validation. This study is the last step in women in situation of less active ectopic pregnancy.
