Criterios clínicos no invasivos para el diagnóstico de endometriosis en pacientes con dolor pélvico crónico: un estudio transversal analítico

Introduction:  The diagnosis of endometriosis in patients with chronic pelvic pain is confirmed by laparoscopy and/or imaging. The lack of non-invasive criteria for the diagnosis of endometriosis has motivated the performance of this study, which aimed to identify sociodemographic and clinical patterns in patients with chronic pelvic pain for the non-invasive diagnosis of this pathology.

Methods:  Cross-sectional analytical study in which data was collected through anonymous surveys from 184 patients with chronic pelvic pain at the Center for Reproductive Medicine and Advanced Gynecological Endoscopy in 2024.

Results:  The study showed a progressive increase in patients with chronic pelvic pain due to endometriosis as age increased within the range of 18 to 35 years, with a progressive decline after 36 years of age. The prevalence of endometriosis in patients with chronic pelvic pain was 74.46 % with OR 20.40, 95 % CI 4.47-93.13, p = 0.0001, being ovarian endometriosis the most frequent variant. 58 % of patients with endometriosis presented chronic pelvic pain with lumbar irradiation, with OR 3.12, 95 % CI 1.20-8.02, p < 0.05. There is a weak, although statistically significant, correlation between the severity of pain and the degree of endometriosis involvement, presenting a Spearman correlation of 0.28 with Student t = 3.21 and p = 0.0018.

Conclusions:  Sociodemographic and clinical patterns were identified that can be used in the early diagnosis of endometriosis in the absence of invasive or imaging methods.
