Purpose: Mineralocorticoid receptor antagonists are the first-line treatment for bilateral adrenal hyperplasia (BAH) with primary aldosteronism (PA), while unilateral adrenalectomy is the standard treatment for aldosterone-producing adenoma (APA). In this study, we investigated the outcomes of patients with BAH after unilateral adrenalectomy and compared them with those of patients with APA. Methods: From January 2010 to November 2018, 102 patients with a diagnosis of PA confirmed by adrenal vein sampling (AVS) and available NP-59 scans were enrolled. All patients underwent unilateral adrenalectomy based on the lateralization test results. We prospectively collected the clinical parameters over 12 months and compared the outcomes of BAH and APA. Results: A total of 102 patients were enrolled in this study: 20 (19.6%) had BAH and 82 (80.4%) had APA. Significant improvements in serum aldosterone-renin ratio (ARR), potassium level, and reduction of antihypertensive drugs were observed in both groups at 12 months after surgery (all p

The aim of this study was to update the information on internationally acceptable standards and clinical practice recommendations for the management of patients with primary aldosteronism (PA). The Taiwan Society of Aldosteronism (TSA) Task Force acknowledged the novel issues of PA and reached a group consensus on PA in Taiwan by collecting the best available evidence and conducting one group meeting, several conference calls, and multiple e-mail communications. Unilateral adrenalectomy is the preferred treatment for patients with aldosterone-producing adenoma (APA). For medical treatment with mineralocorticoid receptor antagonists (MRAs), spironolactone is the first-line treatment, and eplerenone is a reasonable alternative in PA patients intolerant or contraindicated to spironolactone. The dose of MRAs can be titrated according to plasma renin activity (PRA). For screening PA-related comorbidities, we suggest albuminuria to predict a post-treatment decline in renal function, echocardiography as cardiac evaluation, bone mineral density scan for osteoporosis, and obstructive sleep apnea. In tissue and genetic surveys, we suggest immunohistochemical staining and somatic mutation screening for post-operative adrenal specimens in APA patients. With this consensus, we hope to update the information on PA for clinical physicians to facilitate better identification, management and treatment of patients with PA.

Background/Purpose: Even with the increasing recognition of primary aldosteronism (PA) as a cause of refractory hypertension and an issue of public health, the consensus of its optimal surgical or medical treatment in Taiwan has not been reached. Our objective was to develop a clinical practice guideline that is feasible for real-world management of PA patients in Taiwan. Methods: The Taiwan Society of Aldosteronism (TSA) Task Force recognized the above-mentioned issues and reached this Taiwan PA consensus at its inaugural meeting, in order to provide updated information of internationally acceptable standards, and also to incorporate our local disease characteristics and constraints into PA management. Results: In patients with lateralized PA, including aldosterone producing adenoma (APA), laparoscopic adrenalectomy is the ‘gold standard’ of treatment. Mini-laparoscopic and laparoendoscopic single-site approaches are feasible only in highly experienced surgeons. Patients with bilateral adrenal hyperplasia or those not suitable for surgery should be treated by mineralocorticoid receptor antagonists. The outcome data of PA patient management from the literature, especially from PA patients in Taiwan, are reviewed. Mental health screening is helpful in early detection and management of psychopathology among PA patients. Conclusion: We hope this consensus will provide a guideline to help medical professionals to manage PA patients in Taiwan to achieve a better quality of care.

Background/Purpose: Even though the increasing clinical recognition of primary aldosteronism (PA) as a public health issue, its heightened risk profiles and the availability of targeted surgical/medical treatment being more understood, consensus in its diagnosis and management based on medical evidence, while recognizing the constraints of our real-world clinical practice in Taiwan, has not been reached. Methods: The Taiwan Society of Aldosteronism (TSA) Task Force acknowledges the above-mentioned issues and reached this Taiwan PA consensus at its inaugural meeting, in order to provide updated information of internationally acceptable standards, and also to incorporate our local disease characteristics into the management of PA. Results: When there is suspicion of PA, a plasma aldosterone to renin ratio (ARR) should be obtained initially. Patients with abnormal ARR will undergo confirmatory laboratory and image tests. Subtype classification with adrenal venous sampling (AVS) or NP-59 nuclear imaging, if AVS not available, to lateralize PA is recommended when patients are considered for adrenalectomy. The strengths and weaknesses of the currently available identification methods are discussed, focusing especially on result interpretation. Conclusion: With this consensus we hope to raise more awareness of PA among medical professionals and hypertensive patients in Taiwan, and to facilitate reconciliation of better detection, identification and treatment of patients with PA.

Background: We previously reported our initial experience with laparoendoscopic single-site (LESS) retroperitoneal partial adrenalectomy using a custom-made single-port device and conventional straight laparoscopic instruments. Methods: Between December 2010 and February 2012, LESS retroperitoneal partial adrenalectomies were performed in 11 patients. Six patients had aldosterone-producing adenomas (APAs) and five patients had nonfunctioning tumors. A single-port access was created with an Alexis wound retractor (Applied Medical, Rancho Santa Margarita, CA, USA) through an incision of 2–3 cm beneath the tip of the 12th rib. All procedures were performed with straight laparoscopic instruments. Results: All LESS procedures were successfully completed without conversion to traditional laparoscopic conversion. The tumors ranged from 1 cm to 4.7 cm (mean, 2.3 cm). The operative time was 71–257 minutes (mean, 121 minutes). Most patients (n = 8) had minimal blood loss; the other three patients had a blood loss of 150 mL, 100 mL, and 100 mL. The mean hospital stay was 3 days (range, 1–6 days). There were no perioperative or postoperative complications. Pathological examinations revealed negative surgical margins in all specimens. All patients with Conn's syndrome had an improvement in blood pressure and normalization of plasma renin activity and serum aldosterone levels; all patients were free of potassium supplementation. Conclusion: Our results clearly demonstrate that LESS retroperitoneal partial adrenalectomy can be performed safely and effectively using a custom-made single-access platform and standard laparoscopic instruments.

Coil embolization (CE) is believed effective-safe for treating penile veno-occlusive dysfunction (VOD). From 2012 to 2016, refractory impotence prompted four men to seek further treatment, although they underwent six CEs elsewhere. Uncontrolled coils scattered along penile drainage veins including the deep dorsal veins (n = 3), periprostatic plexus (n = 1), iliac vein (n = 1), right pulmonary artery (n = 2), left pulmonary artery (n = 1), and right ventricle (n = 1). The last one occurred in a 40-year-old house builder, and the coil perforated the right ventricle wall and diaphragm 18 months later. Given no sustainable improvement, CE's safety and efficacy are unreliable for treating patients with VOD.
