Mapping of endometriosis in patients with unilateral endometrioma

True Prevalence of Diaphragmatic Endometriosis and Its Association with Severe Endometriosis: A Call for Awareness and Investigation

STUDY OBJECTIVE

To identify characteristics indicating preoperatively the presence of diaphragmatic endometriosis (DE).

DESIGN

Comparison of characteristics of patients with diaphragmatic endometriosis (DE) with characteristics of patients with abdominal endometriosis without diaphragmatic involvement, in a prospective cohort study.

SETTING

Tertiary referral center; endometriosis center.

PATIENTS

A total of 1372 patients with histologically proven endometriosis.

INTERVENTIONS

Surgery performed laparoscopically under general anesthesia. All patients with suspected endometriosis underwent a complete bilateral inspection of the diaphragm.

MEASUREMENTS AND MAIN RESULTS

Demographic and clinical pathologic characteristics were evaluated using basic descriptive statistics (comparison of the groups using the χ2 test and the Mann-Whitney t test). A logistic regression analysis was performed to evaluate the relationship (hazard ratio) between symptoms and the presence of DE. DE was diagnosed in 4.7% of the patients (65 of 1372). There was no significant difference between the 2 groups (patients with abdominal endometriosis with or without DE) with regard to typical endometriosis pain (dysmenorrhea, dyschezia, dysuria, and/or dyspareunia). However, in the DE group, diaphragmatic pain was present significantly more often preoperatively (27.7% vs 1.8%, p <.001). Four DE patients (6.1 %) were asymptomatic (with infertility the indication for surgery). In the DE group, 78.4 % had advanced stages of endometriosis (revised American Fertility Society III° or IV°); the left lower pelvis was affected in more patients (73.8%). In cases of ovarian endometriosis, patients with DE showed a significantly higher prevalence of left ovaries involvement (left 63% vs right 35.7%, p <.001). Patients with DE had a significantly higher rate of infertility (49.2% vs 28.7%, p <.05).

CONCLUSION

Patients with shoulder pain, infertility, and/or endometriosis in the left pelvis have a significant higher risk of DE and therefore need specific preoperative counseling and if indicated surgical treatment.

Tubal Endometriosis: From Bench to Bedside, A Scoping Review

Tubal endometriosis (EM) refers to the detection of ectopic endometrial implants on tubes. It may cause a significant defect of the tubes, translating into dysmenorrhea, pelvic pain, and infertility. We aimed to evaluate the disease characteristics, prevalence, histopathological findings and genetic profile of patients with tubal EM. A thorough search of three electronic databases was performed for studies that presented outcomes of patients with tubal EM. Thirteen studies (four observational, seven case reports, two genetic) were considered eligible for inclusion. The prevalence of tubal EM ranged from 6.9% to 69%. The predominant symptoms for referral of patients were infertility and abdominal pain. Women of reproductive age underwent salpingectomy for the management of the disease. Only one case of malignant transformation was recorded in a 60-year-old patient. The prevalence of tubal EM ranges depending on the indication for surgery, the presence of concomitant pelvic EM and the type of diagnosis and treatment. Further, more extensive, larger studies are warranted to evaluate the impact of tubal EM in the progression and prognosis of EM, the effect of salpingectomy in the improvement of disease-related symptoms and to designate the group of patients that could benefit from risk-reducing salpingectomy based on the risk of developing ovarian malignancy.
