Diagram to map the locations of endometriosis.

Objective: To develop and test a visual map that corresponds practically and objectively to the anatomical areas affected by endometriosis.

Method: The study comprised 150 questionnaires concerning 10 clinical cases of endometriosis presented as a visual diagram that were distributed at 3 different scientific events, among 3 groups of 50 gynecologists. Data were analyzed to evaluate the diagram's ability to graphically represent the endometriosis sites.

Results: After presentation at the first event, the rate of correct answers on the site of endometriosis was 84.7%; at the second event, after modifications implemented after feedback from the first event, the rate of correct answers was 97.4%; and at the third event, when all suggestions and modifications had been made, the rate was 99.7%.

Conclusion: The diagram proposed to map the location of endometriosis lesions appears to be an adequate and effective instrument to represent the site of the disease, with correlation at almost 100%.
