Pathological diagnosis of thoracic endometriosis

Pulmonary Endometriosis: A Systematic Review

Background/Objectives: Endometriosis is characterized by the presence of ectopic endometrial-like glands and stroma outside the endometrial cavity, which mainly occurs in the pelvic cavity. Pulmonary endometriosis, or thoracic endometriosis syndrome (TES), describes the rare presence of endometrial-like cells in the thoracic cavity and includes catamenial pneumothorax, catamenial hemothorax, hemoptysis, and lung nodules. Our aim is to summarize the results of all reported cases of TES. Methods: Extensive research was conducted through MEDLINE/PUBMED using the keywords "thoracic endometriosis", "thoracic endometriosis syndrome", "catamenial pneumothorax", "catamenial hemoptysis", and "TES". Following PRISMA guidelines, all published cases of TES between January 1950 and March 2024 were included. A systematic review of 202 studies in English, including 592 patients, was performed. Results: The median age of women with TES is 33.8 years old. The most common clinical presentation is catamenial pneumothorax (68.4%), while lesions are mainly found in the right lung unilaterally (79.9%). Chest computed tomography (CT) was used alone or after an X-ray to determine the pathological findings. Ground-glass opacity nodules and cystic lesions represent the most common finding in CT, while pneumothorax is the most common finding in X-rays. Video-assisted thoracoscopic surgery (VATS) is the main therapeutic approach, usually in combination with hormonal therapy, including GnRH analogues, progestins, androgens, or combined oral contraceptives. Hormonal therapy was also administered as monotherapy. Symptom recurrence was reported in 10.1% of all cases after the treatment. Conclusions: High clinical awareness and a multidisciplinary approach are necessary for the best clinical outcome for TES patients. More studies are required to extract safer conclusions.

When Menstruation Meets the Pleura: A Rare Case of Catamenial Hemothorax and Thoracic Endometriosis and a Literature Review

Catamenial hemothorax is a rare manifestation of thoracic endometriosis, characterized by blood in the pleural cavity associated with menstrual cycles. We present the case of a 42-year-old woman with recurrent right-sided chest pain and dyspnea coinciding with menstruation. Imaging revealed a large pleural effusion and hemothorax. Diagnostic video-assisted thoracoscopic surgery (VATS) confirmed thoracic endometriosis. The patient received a combination of hormonal therapy and VATS. Follow-ups over 36 months showed significant symptom improvement and resolution of pleural effusion. This case emphasizes the need to consider thoracic endometriosis in women with menstrual-related hemothorax.

Stripping Massage and Literature Review in Post-Thoracoscopic Chest Pain Management

The aim of this randomized study was to investigate whether stripping massage (SM) of myofascial trigger points in the lower rhomboid muscle could alleviate chest pain in patients following thoracoscopic surgery. In addition, a literature review was conducted to assess the effectiveness of various pain management techniques. Sixty adult patients who reported a visual analog scale (VAS) score of 4 or higher were randomly assigned to receive conventional analgesics alone (conventional group) or combined with SM twice daily for 2 weeks (SM group). VAS scores and the use of additional analgesics were evaluated on postoperative days 1, 3, 7, 14, and 30. Using the PubMed and Cochrane Library databases, a review of current pain management techniques was carried out up to January 31, 2022. A subgroup analysis was also performed to examine the treatment effect during different surgical periods and techniques. Results showed that the SM group had significantly lower VAS scores on postoperative days 3, 7, 14, and 30 (p < 0.001), as well as a shorter hospitalization duration and reduced need for additional analgesics (p < 0.001). The literature review included a total of 20 studies (2,342 cases of chest pain relief after thoracoscopic surgery), which indicated that serratus anterior plane (SAP) blocks were commonly used as a perioperative approach to reduce pain and opioid consumption. SM and SAP can both serve as adjuvant treatments for chest pain in patients following thoracoscopic surgery, with SM being a safe and noninvasive pain control option after hospital discharge.

Thoracic Endometriosis Masquerading As Recurrent Hemothorax

Extragenital endometriosis is not a common occurrence. Its diagnosis is often delayed, which leads to further complications and recurrent hospitalizations. In this report, we present a case of a 37-year-old African American female diagnosed with thoracic endometriosis who initially presented with a two-week duration of progressive shortness of breath. The diagnosis of this patient posed a dilemma as there was initial suspicion of ovarian cancer and Meig's syndrome, which can have similar presentations.

An artificial intelligence approach for investigating multifactorial pain-related features of endometriosis

Endometriosis is a debilitating, chronic disease that is estimated to affect 11% of reproductive-age women. Diagnosis of endometriosis is difficult with diagnostic delays of up to 12 years reported. These delays can negatively impact health and quality of life. Vague, nonspecific symptoms, like pain, with multiple differential diagnoses contribute to the difficulty of diagnosis. By investigating previously imprecise symptoms of pain, we sought to clarify distinct pain symptoms indicative of endometriosis, using an artificial intelligence-based approach. We used data from 473 women undergoing laparoscopy or laparotomy for a variety of surgical indications. Multiple anatomical pain locations were clustered based on the associations across samples to increase the power in the probability calculations. A Bayesian network was developed using pain-related features, subfertility, and diagnoses. Univariable and multivariable analyses were performed by querying the network for the relative risk of a postoperative diagnosis, given the presence of different symptoms. Performance and sensitivity analyses demonstrated the advantages of Bayesian network analysis over traditional statistical techniques. Clustering grouped the 155 anatomical sites of pain into 15 pain locations. After pruning, the final Bayesian network included 18 nodes. The presence of any pain-related feature increased the relative risk of endometriosis (p-value < 0.001). The constellation of chronic pelvic pain, subfertility, and dyspareunia resulted in the greatest increase in the relative risk of endometriosis. The performance and sensitivity analyses demonstrated that the Bayesian network could identify and analyze more significant associations with endometriosis than traditional statistical techniques. Pelvic pain, frequently associated with endometriosis, is a common and vague symptom. Our Bayesian network for the study of pain-related features of endometriosis revealed specific pain locations and pain types that potentially forecast the diagnosis of endometriosis.
