Thoracic Endometriosis Syndrome: A Review of Diagnosis and Management

Nezhat C et al., 2019 · JSLS : Journal of the Society of Laparoendoscopic Surgeons · Free full text on PubMed Central

Endometriosis is characterized by the presence of endometrial-like glands and stroma outside the uterine cavity and is believed to affect 6%-10% of reproductive-age women. Endometriosis within the lung parenchyma or on the diaphragm and pleural surfaces produces a range of clinical and radiological manifestations. This includes catamenial pneumothorax, hemothorax, hemoptysis, and pulmonary nodules, resulting in an entity known as thoracic endometriosis syndrome (TES). Computerized searches of MEDLINE and PubMed were conducted using the key words "thoracic endometriosis," "catamenial pneumothorax," "catamenial hemothorax," and "catamenial hemoptysis." References from identified sources were manually searched to allow for a thorough review. TES can produce incapacitating symptoms for some patients. Symptoms of TES are nonspecific, so a high degree of clinical suspicion is warranted. Medical management represents the first-line treatment approach. When this fails or is contraindicated, definitive surgical treatment for cases of suspected TES uses a combined video laparoscopy performed by a gynecologic surgeon and video-assisted thoracoscopic surgery performed by a thoracic surgeon. Postoperative hormonal suppression may further reduce disease recurrence.

Extraperitoneal endometriosis with catamenial pneumothoraces: a review of the literature

Roberts LM et al., 2003 · JSLS

To present a case of recurrent catamenial pneumothorax and diaphragmatic endometriosis that was managed thoracoscopically. A review of the literature is also presented. A-28-year-old woman presented with bloody stools, chronic constipation, and chest pain. A review of systems was positive for monthly chest pain associated with her menses. A preoperative chest x-ray revealed a right pneumothorax. Colonoscopy revealed biopsy proven endometriosis of the sigmoid colon. A pelvic computed tomography scan revealed bilateral complex, cystic and solid adenexal lesions. A right thoracoscopy was performed. A lesion on the right hemidiaphragm was excised and confirmed to be endometriosis. A wedge section of lung tissue containing a bleb was resected and also contained endometriosis. Three months later, the patient underwent laparoscopic excision of her pelvic endometriosis, including a low anterior rectal resection. Five months later, she presented again with right-sided chest pain. A thoracoscopic right total pleurectomy was performed for recurrent pneumothorax. Pullmonary endometriosis may present as chest pain, shortness of breath, or hemoptysis associated with menstrual cycles. This case emphasizes the importance of a careful review of systems in patients with known endometriosis. Management now includes an endoscopic alternative and all of its known benefits.

Hepatic endometriosis: a case report

Cravello L et al., 1996 · Fertil Steril

To describe a case of hepatic endometriosis. Case report. University hospital. A 34-year-old woman with a 2-year history of cyclic right subcostal pain. Gonadotropin-releasing hormone agonist (GnRH-a) therapy followed by surgical resection. Ultrasonography, computed tomography scan, and magnetic resonance imaging of the liver disclosed a 6-cm diameter mass. The GnRH-a therapy for 4 months led to clinical and radiologic improvement. Surgery performed to allow pregnancy confirmed the diagnosis of hepatic endometriosis. Hepatic endometriosis is uncommon. It may result from metaplasia of the peritoneum or from hematogenic or lymphatic spread.

Treatment of pulmonary endometriosis with a long-acting GnRH agonist

Seltzer VL et al., 1990 · Obstet Gynecol

We report the case of a patient who was successfully treated with a long-acting GnRH agonist for pulmonary endometriosis. This 28-year-old woman had symptomatic pleural endometriosis, documented by biopsies, as well as symptomatic pelvic endometriosis. Two surgical procedures, consisting of excision of pleural endometriotic tissue and partial pleurectomies, failed to relieve her chest symptoms. Little relief was achieved with pseudopregnancy treatment. Satisfactory symptomatic improvement was obtained with danazol, but this medication had to be discontinued because of severe side effects. Trial of a GnRH agonist, leuprolide acetate, achieved complete remission of her chest symptoms; in addition, the patient became pregnant immediately after cessation of therapy. Gonadotropin-releasing hormone agonist therapy may be an important therapeutic alternative for women with pulmonary endometriosis who cannot tolerate danazol treatment and in whom surgical therapy fails to relieve the chest symptoms.
