Abstract

Objective Endometriosis is a complex disease, and pain is an important component of the syndrome. One of the most used methods to assess pain is the visual analogue scale (VAS). The aim of the present research was to study the pain experienced by patients who referred to our unit for endometriosis, using the VAS to understand the variables that could influence it.

Methods We have conducted a prospective study from February 2012 to December 2016, enrolling 388 patients who referred to a university hospital, in Florence, Italy. We have included in the present study patients during their follow-up for endometriosis; we have also included patients who underwent surgery with a histological diagnosis of endometriosis. We have collected sociodemographic and clinical information regarding age, body mass index (BMI), smoking habit, number of pregnancies, and endometriosis staging. Finally, we have administered the VAS for several symptoms.

Results Dysmenorrhea was the symptom associated with the highest perception of pain (mean VAS score of 5.76). The logistic regression showed that the stage of endometriosis could influence the pain associated to constipation and to dysuria. The linear regression showed that age could influence the pain associated to constipation, to dyspareunia, and to dysmenorrhea. A positive correlation was found between dysmenorrhea and chronic pelvic pain (CPP), between dysmenorrhea and dyspareunia, and between constipation and dysuria.

Conclusion Using a validated method, the VAS, we have studied the pain experienced by a group of patients with a history of endometriosis and observed that smoking habit and BMI did not influence the VAS scores, and that dysmenorrhea was associated with the highest perception of pain.

Resumo

Objetivo A endometriose é uma doença complexa, e a dor é um componente importante da enfermidade. Um dos métodos mais utilizados para avaliar a dor é a escala visual analógica (EVA). O objetivo da presente pesquisa foi estudar a dor sentida pelas pacientes que se referiram à nossa unidade para endometriose, usando a EVA para entender as variáveis que poderiam influenciá-la.

Métodos Realizamos um estudo transversal de fevereiro de 2012 a dezembro de 2016, envolvendo 388 pacientes que se referiram a um hospital universitário, em Florença, Itália. Incluímos nossos pacientes do estudo durante o acompanhamento da endometriose; incluímos também pacientes que se submeteram à cirurgia com diagnóstico histológico de endometriose. Coletamos informações sociodemográficas e clínicas sobre idade, índice de massa corporal (IMC), hábito de fumar, número de gravidezes e estágio da endometriose. Finalmente, administramos a EVA para vários sintomas.

Resultados A dismenorreia foi o sintoma associado à maior percepção de dor (média do escore EVA de 5,76). A regressão logística mostrou que o estágio da endometriose poderia influenciar a dor associada à constipação e à disúria. A regressão linear mostrou que a idade poderia influenciar a dor associada à constipação, à dispareunia e à dismenorreia. Uma correlação positiva foi encontrada entre dismenorreia e dor pélvica crônica, entre dismenorreia e dispareunia, e entre constipação e disúria.

Conclusão Utilizando um método validado, a EVA, estudamos a dor sentida por um grupo de pacientes com história de endometriose e observamos que o hábito de fumar e o IMC não influenciaram os escores EVA, e que a dismenorreia foi associada à maior percepção de dor.
