Abstract Hydrosalpinx is a disease characterized by the obstruction of the salpinx, with progressive accumulation in the shape of a fluid-filled sac at the distal part of the tuba uterina, and closed to the ovary. Women with hydrosalpinges have lower implantation and pregnancy rates due to a combination of mechanical and chemical factors thought to disrupt the endometrial environment. Evidence suggests that the presence of hydrosalpinx reduces the rate of pregnancy with assisted reproductive technology. The main aim of the present is review to make an overview of the possible effects of hydrosalpinx on in vitro fertilization (IVF).We conducted a literature search on the PubMed, Ovid MEDLINE, and Google Scholar data bases regarding hydrosalpinx and IVF outcomes. Hydrosalpinx probably has a direct toxic effect on sperm motility and on the embryos. In addition, the increasing liquid inside the salpinges could alter the mechanisms of endometrial receptivity. The window of endometrial receptivity is essential in the implantation of blastocysts, and it triggers multiple reactions arising from the endometrium as well as the blastocysts. Hydrosalpinx could influence the expression of homeobox A10 (HOXA10) gene, which plays an essential role in directing embryonic development and implantation. Salpingectomy restores the endometrial expression of HOXA10; therefore, it may be one mechanism by which tubal

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 sesubmeteramàcirurgia comdiagnóstico 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.

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 couldinfluencethe 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.
