Review
The interest on partial adrenalectomy has steadily increased over the past twenty years. Adrenal pathologies are mostly benign, making an organ-preserving procedure attractive for many patients. The introduction of minimally invasive techniques played probably an important role in this process because they transformed a complex surgical procedure, related to the difficult access to the retroperitoneal space, into a simple operation improving the accessibility to this organ. In this review we summarize the role of partial retroperitoneoscopic adrenalectomy over the years and the current indications and technique.

Meta-Analysis
CONTEXT
Adrenal medullary hyperplasia (AMH) is a rare, incompletely described disorder of the adrenal medulla that is associated with catecholamine excess.
OBJECTIVE
To increase knowledge about AMH by reviewing the reported cases of this disorder.
DESIGN
Systematic review and meta-analysis of the genotype/phenotype relationship in all reported cases of AMH.
SETTING
Literature review and analysis.
PATIENTS OR OTHER PARTICIPANTS
All cases of AMH published to date.
MAIN OUTCOME MEASURE(S)
Characteristics of AMH cases and genotype-phenotype relationships.
RESULTS
A total of 66 patients, median age of 48 years, were identified from 29 reports. More than one-half were male (n = 39, 59%). The majority had unilateral (73%, n = 48) disease; 71% (n = 47) were sporadic and 23% (n = 15) were associated with the MEN2. Most (91%, n = 60) displayed signs and symptoms of excess catecholamine secretion, particularly hypertension. Elevated catecholamine concentrations (86%, n = 57) and adrenal abnormalities on imaging were common (80%, n = 53). More than one-half (58%, n = 38) had concurrent tumors: pheochromocytoma (42%, n = 16/38); medullary thyroid cancer (24%, n = 9/38); and adrenocortical adenoma (29%, n = 11/38). Most (88%, n = 58) underwent adrenalectomy with 45/58 achieving symptom resolution. Adrenalectomy was less common in patients under 40 years and those with bilateral disease (both P < .05).
CONCLUSION
AMH may be sporadic or associated with MEN2, most have catecholamine excess and imaging abnormalities. Unilateral involvement is more common. Most reported patients have been treated with adrenalectomy, which is usually curative with regard to catecholamine hypersecretion.

Background and Objectives: Laparoscopic adrenalectomy (LA) is the standard surgical approach for adrenalectomy. At present, robotic adrenalectomy (RA) has been introduced at various hospitals. This study evaluated our initial experience with robotic adrenalectomy compared with conventional laparoscopic adrenalectomy. Materials and Methods: From October 2018 to March 2022, 56 adrenalectomies were performed by a single endocrine surgeon. Thirty-two patients underwent LA (LA group), and twenty-four patients underwent RA (RA group). Results: Patients in the RA group were significantly younger than those in the LA group (48.6 ± 9.7 years vs. 55.1 ± 11.4 years, p = 0.013). The RA group had a shorter operation time than the LA group (76.1 ± 28.2 min vs. 118.0 ± 54.3 min, p < 0.001). The length of hospital stay and postoperative pain level between the two groups were similar. There were no complications in the RA group. There was no significant difference in the pathologic diagnosis between the two groups. The cost of surgery was significantly higher in the RA group than in the LA group (5288.5 US dollars vs. 441.5 ± 136.8 US dollars, p < 0.001). Conclusions: In our initial experience, RA showed a shorter operation time than LA and no complications. RA could be a viable alternative surgical option for adrenalectomy, notwithstanding its higher cost.

CASE SERIES SUMMARY
Twenty-nine cats from different institutions with confirmed or highly suspected primary hyperaldosteronism treated by unilateral adrenalectomy were retrospectively included in this study. The most frequent clinical signs were lethargy (n = 20; 69%) and neck ventroflexion (n = 17; 59%). Hypokalaemia was present in all cats, creatinine kinase was elevated in 15 and hyperaldosteronism was documented in 24. Hypertension was frequently encountered (n = 24; 89%). Preoperative treatment included potassium supplementation (n = 19; 66%), spironolactone (n = 16; 55%) and amlodipine (n = 11; 38%). There were 13 adrenal masses on the right side, 15 on the left and, in one cat, no side was reported. The median adrenal mass size was 2 × 1.5 cm (range 1-4.6 × 0.4-3.8); vascular invasion was present in five cats, involving the caudal vena cava in four cats and the renal vein in one. Median duration of surgery was 57 mins. One major intraoperative complication (3%) was reported and consisted of haemorrhage during the removal of a neoplastic thrombus from the caudal vena cava. In 4/29 cats (14%), minor postoperative complications occurred and were treated medically. One fatal complication (3%) was observed, likely due to disseminated intravascular coagulation. The median duration of hospitalisation was 4 days; 97% of cats survived to discharge. The potassium level normalised in 24 cats within 3 months of surgery; hypertension resolved in 21/23 cats. Follow-up was available for 25 cats with a median survival of 1082 days. Death in the long-term follow-up was mainly related to worsening of comorbidities.
RELEVANCE AND NOVEL INFORMATION
Adrenalectomy appears to be a safe and effective treatment with a high rate of survival and a low rate of major complications. Long-term medical treatment was not required.

Review
Primary aldosteronism (PA) in pregnancy (PAP) can be a serious condition and is challenging to diagnose. This study was conceived to help in the diagnosis of PAP and provide suggestions on management of PAP based on evidence retrieved using a Population, Intervention, Comparison, and Outcome search strategy. Based on the changes of aldosterone and renin occurring in normal pregnancies, we developed a nomogram that will allow to identify PAP cases. Moreover, we found that published PAP cases fell into 4 main groups differing for management and outcomes: (1) unilateral medically treated, (2) unilateral surgically treated, (3) bilateral medically treated and (4) familial forms. Results showed that complications involved 62.2% of pregnant women with nonfamilial PA and 18.5% of those with familial hyperaldosteronism type I. Adrenalectomy during pregnancy in women with PAP did not improve maternal and fetal outcomes, over medical treatment alone. Moreover, cure of maternal hypertension and mother and baby outcome were better when unilateral PA was discovered and surgically treated before or after pregnancy. Therefore, fertile women with arterial hypertension should be screened for PA before pregnancy and, if necessary, subtyped to identify unilateral forms of PA. This will allow to furnish adequate counseling, a chance for surgical cure and, therefore, for a pregnancy not complicated by aldosterone excess.

Review
INTRODUCTION The 2012 British Association of Endocrine and Thyroid Surgeons audit report showed that only 86 of 1359 patients who underwent adrenalectomy had a bilateral operation; thus the experience with this procedure remains limited. METHODS Retrospective review of patients undergoing bilateral adrenalectomy in a tertiary referral centre. RESULTS Between November 2005 and January 2016, bilateral adrenalectomy was performed in 23 patients (6 male, 17 female, age 43 ± 4 years) diagnosed with Cushing's disease (n = 13), hereditary phaeochromocytomas (n = 6), adrenocortical cancer (n = 2), colorectal metastatic disease (n = 1) and adrenocortical adenomas (n = 1). A laparoscopic transperitoneal approach was used in 17 patients, with one conversion to open. Three patients had open adrenalectomies for adrenocortical cancer and for simultaneous phaeochromocytomas and pancreatic neuroendocrine tumours in a patient with Von Hippel-Lindau syndrome. Three patients with Cushing's had a bilateral retroperitoneoscopic operation. The mean operating time was 195 ± 16 minutes for laparoscopic operations (n = 16), 243 ± 44 minutes for open adrenalectomies (n = 4) and 151 ± 12 minutes for retroperitoneal operations. It was significantly shorter for Cushing's disease than for phaeochromocytomas (162 ± 8 vs. 257 ± 39 minutes, P < 0.01). Median length of hospital stay was 5 days. Postoperative complications (Clavien-Dindo classification) included one chest infection (level 2), one postoperative haemorrhage and two chest drains for pneumothorax (level 3), two postoperative cardiac arrests (level 4) and one late cancer death from complications related to uncontrolled hypercortisolism (level 5). DISCUSSION Synchronous bilateral adrenalectomy remains an infrequent operation. The laparoscopic approach is feasible in the majority of patients. It is likely that the retroperitoneoscopic adrenalectomy will become the standard approach for bilateral operations.

Review
The importance of an early diagnosis and appropriate management of patients with primary aldosteronism (PA) has become increasingly clear because of the adverse impact of the disorder on cardiovascular and cerebrovascular events and target organ damage. Adrenalectomy potentially cures patients with unilateral PA resulting in normalisation of blood pressure or significant clinical improvements in the majority of patients. Different criteria have been used to evaluate outcomes of unilateral adrenalectomy. Clinical remission (cure of hypertension) is observed in 6% to 86% of patients and clinical benefits from surgery are seen in the majority. Several factors have been identified that predict clinical success after surgery such as age, sex, anti-hypertensive medication dosage and known duration of hypertension. Biochemical remission of PA after unilateral adrenalectomy, characterised by the resolution of hyperaldosteronism and correction of pre-surgical hypokalaemia, is observed in 67% to 100% of patients with unilateral PA. In only a small proportion of patients, adrenalectomy fails to resolve hyperaldosteronism and inappropriate aldosterone production persists after surgery. In this review we discuss the potential reasons for failing to cure hyperaldosteronism after unilateral adrenalectomy for unilateral primary aldosteronism.

Meta-Analysis
BACKGROUND
Studies have suggested differences in postoperative outcomes between patients with obesity and those without following adrenalectomy, but these remained to be ascertained with synthesis of available evidence. The aim of this systematic review and meta-analysis was to investigate the association between obesity and outcomes of patients after laparoscopic adrenalectomy.
METHODS
We searched EMBASE, PubMed, Global Index Medicus, and Web of Science, without language restriction, to identify cohort studies published between January 1, 2000 and November 6, 2019. We considered studies with data comparing outcomes of adults with and without obesity after laparoscopic adrenalectomy. Random-effects meta-analysis was used to pool study-specific estimates. This review was registered with PROSPERO, CRD42018117070.
RESULTS
Five studies with data on a pooled sample of 353 patients with obesity and 828 without were included in the meta-analysis. The risk of bias was moderate to low. We found no association between obesity and the various stages of postoperative complications: Clavien-Dindo grade 1 (OR = 1.57; 95%CI = 0.55-4.48; I = 44.6%), grade 2 (OR = 1.12; 95%CI = 0.54-2.32; I = 0.0%), grade 3 (OR = 1.79; 95%CI = 0.58-5.47; I = 0.0%;), grade 4 (OR = 0.43; 95%CI = 0.05-3.71; I = 0.0%), and grade 5 (death) (OR = 0.43; 95% CI = 0.02-14.31). Furthermore, no association was found between obesity and readmission rates (OR = 0.7; 95% CI = 0.13-3.62) and conversion of laparoscopic to open surgery (OR = 0.62; 95% CI = 0.16-2.34; I = 19.5%).
CONCLUSIONS
This study suggests that obesity is not associated with complications following laparoscopic adrenalectomy. This meta-analysis might have been underpowered to detect a true association between obesity and patient outcome after laparoscopic adrenalectomy due to the small number of included studies. Larger studies are needed to clarify the role of obesity in patients undergoing laparoscopic adrenalectomy.

Review
A best evidence topic in cardiothoracic surgery was written according to a structured protocol. The question addressed was 'in [patients with isolated adrenal metastasis from operable/operated non-small cell lung cancer] is [adrenalectomy] superior [to chemo/radiotherapy alone for achieving long-term survival]?' Altogether >160 papers were found using the reported search, of which 3 represented the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated. We conclude that the body of evidence is small, retrospective and not formally controlled. As such interpretation is limited by selection bias in assignment of patients. These limitations notwithstanding, surgical resection is associated with prolonged survival for patients with isolated adrenal metastasis from non-small cell lung cancer (NSCLC). Patient selection is probably critical. Factors that are important are: otherwise early tumour, node (TN) status of the lung primary and R0 resection, long disease-free interval and confidence that there are no other sites of metastasis. Patients with ipsilateral adrenal metastasis may derive the greatest survival benefit from adrenalectomy, since spread to the ipsilateral gland may occur via direct lymphatic channels in the retroperitoneum. Involvement of the contralateral adrenal may signify haematogenous spread and therefore, a more aggressive process. Adrenalectomy must be accompanied by regional lymph node clearance to reduce the chance of further spread from the adrenal itself.
