True mesothelial cyst of the adrenal gland: its clinical profile and management.

The incidence of adrenal cysts is 0.06% and only 9% of these are true mesothelial cysts. Here, we present a case of a true mesothelial cyst together with a review of the literature. A female in her 30s presented to the surgical outpatient department complaining of right flank pain. Her contrast-enhanced CT scan revealed a 7.5×6.5×4.5 cm right adrenal gland cyst. The patient underwent a laparoscopic right adrenalectomy. Immunohistopathology revealed the cyst to be mesothelial in nature. The majority of true mesothelial adrenal cysts are benign, unilateral and more common in women. Any adrenal cyst diagnosed as a functional lesion or one that may be malignant or with a diameter of 5 cm or greater requires surgical care whereas smaller lesions can be managed conservatively. Laparoscopic adrenalectomy for an adrenal cyst of diameter greater than 6 cm is a safe and feasible procedure in expert hands if there is no invasion of surrounding tissue.

Giant adrenal gland pseudo-cyst: a case report with literature review.

Adrenal Gland Cysts are rare among all the pathologic cysts that occur in human beings; the pseudo-cyst variety even rarer. Adrenal pseudo-cysts are asymptomatic, non-functional, small, and incidentally discovered disease entities. Their clinical presentation is usually the result of their mass effects. Thanks to the advanced diagnostic technology, more such cases are being discovered timely and managed surgically, before life-threatening complications occur. Open surgical treatment remains the treatment of choice for giant cysts.

Cystic lesions of the adrenal gland.

Cystic lesions of the adrenal glands are relatively uncommon and most of them are clinically silent. Though rarely associated with malignant changes, they may carry clinically detrimental consequences if misdiagnosed. Cystic adrenal lesions exhibit a broad histomorphological spectrum, ranging from pseudocysts, endothelial cysts, epithelial cysts and parasitic cysts. Here we present the case of a young woman with left-sided abdominal pain and contrast-enhanced CT showing a 10.4×7.7×7.8 cm fluid-filled left suprarenal lesion. The patient underwent exploratory laparotomy with cyst excision, and the histopathological examination of the specimen revealed a pseudocyst of the left adrenal gland. Despite being rare, usually benign and asymptomatic, the diagnosis and management of these cystic lesions of the adrenal glands are often unclear. Any functional lesion, potentially malignant lesion or lesion more than 5 cm deserves surgical management, whereas others can be managed conservatively.

LAPAROSCOPIC ADRENAL-SPARING SURGERY CASE SERIES: PARTIAL ADRENALECTOMY AND CYST RESECTION.

The aim is to present our case series documenting indications, laparoscopic technique, surgical and endocrinologic outcomes of laparoscopic partial adrenalectomy. In the period from April 2011 until October 2021, we performed 39 procedures. The patients were divided into three groups: unilateral adrenal gland tumor with a normal contralateral gland (group 1), tumor of the solitary adrenal gland (group 2), and adrenal cysts (group 3). There were 20 patients in group 1, 6 patients in group 2, and 13 patients in group 3. The most common histology in group 1 was adenoma (40%), all tumors in group 2 were renal cell carcinoma metastases, and all cysts in group 3 were benign. There were no major complications (Clavien Dindo grade ≥2) in the whole cohort. All patients in groups 1 and 3 had favorable endocrinologic outcomes, and 50% of group 2 patients required lifelong hydrocortisone replacement therapy. The procedure is safe and feasible with favorable outcomes in the hands of a high volume adrenal surgeon.

Laparoscopic excision of a large adrenal pseudocyst: diagnostic dilemma and technical challenges.

A woman in her 40s attended the hospital with worsening left upper abdominal dull aching pain for the past 6 months. Clinical examination and radiological investigations with ultrasonography and contrast-enhanced CT of the abdomen confirmed it to be a cystic lesion of the left adrenal of size 13 cm × 12 cm × 11 cm. With the possibility of an incidental malignancy due to large size, laparoscopic cyst excision meticulously without spillage of cyst content was possible due to preoperative planning. It was a difficult task to mobilise the cyst intact due to the thin wall to prevent accidental rupture and gross spillage of the cyst contents. The cyst wall sent for histopathological examination confirmed it to be an adrenal pseudocyst without any malignant focus. Adrenal pseudocysts are rare and mostly benign. However, the index of suspecting a malignancy should be high in large cysts, and meticulous dissection is warranted.

A 15-Year Change of an Adrenal Endothelial Cyst.

BACKGROUND Adrenal gland cysts are rare and often occur without any symptoms. Even with advanced imaging modalities, it is still difficult to differentiate a benign adrenal neoplasm from a malignant one. Therefore, it is difficult to arrive at a definitive diagnosis and provide treatment. CASE REPORT We describe a patient with asymptomatic adrenal incidentaloma. The patient was lost to follow-up until 7 years later. On resuming follow-up, an enlarged suprarenal tumor was noted on ultrasound imaging. Magnetic resonance imaging revealed a 6×4 cm tumor mass, and the peripheral part expressed progressive enhancement on dynamic contrast-enhanced images. Laboratory data showed slight hypokalemia, and a complete endocrine assessment was performed, which showed no abnormality. Because malignancy of the adrenal gland remained suspected, a laparoscopic adenectomy was performed. The pathological result showed an adrenal endothelial (vascular) cyst with the formation of thrombi and calcification, without any evidence of malignancy. CONCLUSIONS Adrenal cystic lesions can change with time. Routine imaging studies during follow-up are recommended, and endocrine evaluations should be performed as an initial adrenal tumor work-up. Surgery is the treatment of choice when the cyst is >6 cm in size, malignancy is suspected, or abnormal endocrine activity is present.

[Bilateral macronodular adrenal hyperplasia: a rare cause of Cushing's syndrome (a case report)]. / Hyperplasie macronodulaire bilatérale des surrénales: cause rare du syndrome de Cushing (à propos d'un cas).

Bilateral macronodular adrenal hyperplasia (BMAH) is a rare cause of adrenal Cushing's syndrome, accounting for less than 1% of cases. We here report the case of a 48-year-old patient with diabetes and hypertension presenting with clinical signs of Cushing's syndrome. Etiological assessment enabled clinicians to retain the diagnosis of Adrenocorticotropic hormone (ACTH)-independent hypercortisolism associated with BMAH. Unilateral left adrenalectomy was performed based on noriodocholesterol scintigraphy results, with good outcome. However, given the risk of recurrence and cardiovascular complications, long-term monitoring was scheduled.

Adrenocorticotropic hormone (ACTH) independent Cushing's syndrome due to unilateral adrenocortical hyperplasia: two case reports.

Adrenal unilateral macronodular hyperplasia is a rare cause of Cushing's syndrome. We discuss the case of two patients who present Cushing syndrome due to unilateral adrenal hyperplasia. They presented the signs of clinical hypercorticism as well as metabolic, cardiovascular and osteoporotic complications. Both patients presented clinical and laboratory signs of adrenocorticotropic hormone (ACTH)-independent Cushing syndrome with elevated urinary free cortisol (UFC) levels, adrenal computed tomography (CT) scan revealed the appearance of unilateral adrenal adenoma and normal contralateral adrenal gland. Adrenalectomy was performed under laparoscopic surgery; the resected mass was pathologically diagnosed as unilateral nodular adrenal hyperplasia. Unilateral adrenal hyperplasia is a very rare etiology of ACTH-independent Cushing syndrome, often mistaken for adenoma on CT and only pathological examination can confirm the diagnosis.

Somatic mutations in adrenals from patients with primary aldosteronism not cured after adrenalectomy suggest common pathogenic mechanisms between unilateral and bilateral disease.

OBJECTIVE: Primary aldosteronism (PA) is the most common form of secondary and curable hypertension. Different germline and somatic mutations are found in aldosterone-producing adenoma (APA) and familial forms of the disease, while the causes of bilateral adrenal hyperplasia (BAH) remain largely unknown. Adrenalectomy is the recommended treatment for patients with APA; however, 6% of patients are not cured and show persistent PA after surgery suggesting BAH. The objective of this study was to analyze clinical data of patients with APA without biochemical success after adrenalectomy as well as the histological and genetic characteristics of their adrenal glands. DESIGN AND METHODS: Clinical data of 12 patients with partial and absent biochemical cure were compared to those from 39 PA patients with hormonal cure after surgery. Histological, morphological, and genetic characterization of the adrenals was carried out by CYP11B2 and CYP11B1 immunostaining and by CYP11B2-guided NGS. RESULTS: Patients with absent hormonal cure displayed a longer duration of arterial hypertension and lower lateralization index of aldosterone production. In ten patients, APAs expressing CYP11B2 were identified. No difference in histological and morphological characteristics was observed between patients with or without a hormonal cure. Somatic mutations in APA driver genes were identified in all CYP11B2 positive APAs; CACNA1D mutations were the most frequent genetic abnormality. CONCLUSIONS: Patients with partial and absent biochemical cure were diagnosed later and exhibited a lower lateralization index of aldosterone production, suggesting asymmetric aldosterone production in the context of BAH. Somatic mutations in adrenal glands from those patients indicate common mechanisms underlying BAH and APA.

The Potential of Computed Tomography Volumetry for the Surgical Treatment in Bilateral Macronodular Adrenal Hyperplasia: A Case Report.

Although adrenal resection is a major option to control hypercortisolemia in patients with bilateral macronodular adrenal hyperplasia, a predictive method for postoperative cortisol production has not been established. A 53-year-old man with ulcerative colitis was referred to our hospital for bilateral multiple adrenal nodules and hypertension. Physical and endocrinological examination revealed inappropriate cortisol production and suppressed secretion of adrenocorticotropic hormone with no typical signs of Cushing's syndrome. Imaging analysis revealed bilateral adrenal nodular enlargement, the nodules of which had the radiological features of adrenocortical adenomas without inter-nodular heterogeneity. In addition, computed tomography volumetry demonstrated that the left adrenal gland (70 mL) accounts for three quarters of the total adrenal volume (93 mL). The patient was diagnosed as subclinical Cushing's syndrome due to bilateral macronodular adrenal hyperplasia, and subsequently underwent a left laparoscopic adrenalectomy with the estimation of 75% decrease in the cortisol level based on the adrenal volume. The surgical treatment ultimately resulted in control of the cortisol level within the normal range, which was compatible to our preoperative prediction. However, regardless of the sufficient cortisol level, ulcerative colitis was exacerbated after the surgery, which needed a systemic therapy for remission. This case indicates successful surgical control of hypercortisolemia based on computed tomography volumetry in bilateral macronodular adrenal hyperplasia, as well as the perioperative exacerbation risk for inflammatory diseases in Cushing's syndrome. We report the potential utility of computed tomography volumetry as a quantitative method with retrospective evaluation of our historical cases.

Thermal ablation in adrenal disorders: a discussion of the technology, the clinical evidence and the future.

PURPOSE OF REVIEW: To summarise the emerging role of thermal ablation as a therapeutic modality in the management of functioning adrenal tumours and metastases to the adrenal gland. RECENT FINDINGS: Observational evidence has demonstrated the benefit of thermal ablation in (i) resolving adrenal endocrinopathy arising from benign adenomas, (ii) treating solitary metastases to the adrenal and (iii) controlling metastatic adrenocortical carcinoma and phaeochromocytoma/paraganglioma. SUMMARY: Microwave thermal ablation offers a promising, minimally invasive therapeutic modality for the management of functioning adrenocortical adenomas and adrenal metastases. Appropriate technological design, treatment planning and choice of imaging modality are necessary to overcome technical challenges associated with this emerging therapeutic approach.

Laparoscopic transperitoneal adrenalectomy: a comparative study of different techniques for vessel sealing.

BACKGROUND: Laparoscopic adrenalectomy is the standard surgical approach to adrenal lesions. Adrenal vessel sealing is the critical surgical phase of laparoscopic adrenalectomy. This study aimed at comparing perioperative outcomes of laparoscopic transperitoneal adrenalectomy by means of radiofrequency energy-based device (LARFD) to those performed with traditional clipping device (LACD), while focusing on the different adrenal vessel control techniques. METHODS: Patients who underwent adrenalectomy for adrenal disease between January 1994 and April 2019 at the Surgical Clinic, Polytechnic University of Marche were included in the study. Overall, 414 patients met inclusion criteria for study eligibility: 211 and 203 patients underwent LARFD and LACD, respectively. Multiple models of quantile regression, logistic regression and Poisson finite mixture regression were used to assess the relationship between operative time, conversion to open procedure, length of stay (LoS), surgical procedure and patient characteristics, respectively. RESULTS: LARFD reduced operative time of about 12 min compared to LACD. Additional operative time-related factors were surgery side, surgery approach, conversion to open procedure and trocar number. The probability of conversion to open procedure decreased by about 76% for each added trocar, whereas it increased by about 49% for each added centimeter of adrenal lesion and by about 25% for each added year of surgery. Two patient clusters were identified based on the LoS: long-stay and short-stay. In the long-stay cluster, LoS decreased of about 30% in LARFD group and it was significantly associated with conversion to open procedure and postoperative complications, whereas in short-stay cluster only postoperative complications had a significant effect on LoS. CONCLUSION: Laparoscopic transperitoneal adrenalectomy performed by means of radiofrequency energy-based device for the sealing of adrenal vessels is an effective procedure reducing operative time with potentially improved postoperative outcomes.

Is same-day discharge associated with increased 30-day postoperative complications and readmissions in patients undergoing laparoscopic adrenalectomy?

BACKGROUND: Advances in minimally invasive surgery and perioperative care have decreased substantially the duration of time that patients spend recovering in hospital, with many laparoscopic procedures now being performed on an ambulatory basis. There are limited studies, however, on same-day discharge after laparoscopic adrenalectomy. The objectives of this study were to investigate the outcomes and trends of ambulatory laparoscopic adrenalectomy in a multicenter cohort of patients. METHODS: Adult patients who underwent elective laparoscopic adrenalectomy between 2005 and 2016 were identified in the database of the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP). Baseline demographics and 30-day outcomes were compared between patients who underwent ambulatory laparoscopic adrenalectomy and those who were discharged after an inpatient stay. Multivariable logistic regression and Cox proportional hazards modelling were used to investigate the association between same-day discharge and 30-day complications and unplanned readmissions. RESULTS: Of the 4,807 patients included in the study, 88 (1.8%) underwent ambulatory laparoscopic adrenalectomy and 4,719 (98.2%) were admitted after the adrenalectomy. The same-day discharge group contained fewer obese patients (37.2% vs 50%; P = .04), a lesser proportion of American Society of Anesthesiologists class III patients (45.5% vs 61%; P = .003), and more patients with primary aldosteronism (14.8% vs 6%; P = .002) compared with the inpatient group. After adjustment for confounders, same-day discharge was not associated with 30-day overall complications (OR 1.17, 95% CI 0.35-3.85; P = .80) or unplanned readmissions (HR 2.77, 95% CI 0.86-8.96; P = .09). The percentage of laparoscopic adrenalectomies performed on an ambulatory basis at hospitals participating in the ACS NSQIP remained low throughout the study period (0-3.1% per year) with no evidence of an increasing trend over time (P = .21). CONCLUSION: Ambulatory laparoscopic adrenalectomy is a safe and feasible alternative to inpatient hospitalization in selected patients. Further study is needed to determine the cost savings, barriers to uptake, and optimal selection criteria for this approach.

Robotic and Laparoscopic Approaches for Adrenal Surgery in Obese Patients.

OBJECTIVE: Minimally invasive adrenalectomy is a challenging procedure in obese patients. Few recent studies have advocated against robot-assisted adrenalectomy, particularly in obese patients. This study aims to compare operative outcomes between the robotic and laparoscopic adrenalectomy, particularly in obese patients. MATERIALS AND METHODS: A retrospective analysis was performed on all consecutive patients undergoing adrenalectomy for benign disease by a single surgeon using either a laparoscopic or robotic approach. Adrenal surgeries for adrenal cancer were excluded. Demographics, operative time, length of hospital stays, estimated blood loss (EBL), and intraoperative and postoperative complications were evaluated. Patients were divided into 2 groups; obese and nonobese. A sub-analysis was performed comparing robotic and laparoscopic approaches in obese and nonobese patients. RESULTS: Out of 120, 55 (45.83%) were obese (body mass index ≥ 30 kg/m2). 14 (25.45%) of the obese patients underwent a laparoscopic approach, and 41 (74.55%) underwent a robotic approach. Operative times were longer in the obese vs. nonobese groups (173.30 ± 72.90 minutes and 148.20 ± 61.68 minutes, P = .04) and were associated with less EBL (53.77 ± 82.48 vs. 101.30 ± 122, P = .01). The robotic approach required a longer operative time when compared to the laparoscopic approach (187 ± 72.42 minutes vs. 126.60 ± 54.55 minutes, P = .0102) in the obese but was associated with less blood loss (29.02 ± 51.05 mL vs. 138.30 ± 112.20 mL, P < .01) and shorter hospital stay (1.73 ± 1.23 days vs. 3.17 ± 1.27 days, P < .001). CONCLUSION: Robot-assisted adrenal surgery is safe in obese patients and appears to be longer; however, it provides improvements in postoperative outcomes, including EBL and shorter hospital stay.

Modified three-level techniques of retroperitoneal laparoscopic procedures to treat adrenal lesions for patients with BMI ≥ 25 Kg/m2.

Objective: To evaluate the modified Zhang's 'three-level' technique of retroperitoneal laparoscopic adrenalectomy (RLA) to treat adrenal lesions for patients with BMI of 25-30 Kg/m2. Methods: A retrospective analysis was performed in all patients with BMI of 25-30 Kg/m2 in our hospital from January 2014 to December 2019. Those who underwent laparoscopic adrenal surgery were divided into two groups on the basis of the technique used: the Zhang's technique (the ZT group) and the modified technique (the MT group). Results: Herein, 170 operations were included (ZT, 91 patients; MT, 79 patients). RLA was successfully performed in all of them. Compared with the ZT group patients, the MT group patients showed shorter operation time (p = 0.007), lesser intraoperative blood loss (p = 0.023), shorter operation time, earlier postoperative diet recovery (p < 0.001), shorter postoperative drainage time (p < 0.001) and shorter postoperative hospitalization period (p = 0.001). It was also worth noting that the unplanned total adrenalectomy rate was significantly less in the MT group than in the ZT group (0% vs. 10.8%, p = 0.020). There was no significant difference in the complications between the two groups (3.3% vs. 2.5%, p = 0.567). Conclusions: We found that MT was a beneficial retroperitoneal laparoscopic treatment for adrenal lesions in patients who had a BMI of 25-30 Kg/m2. It may provide a reference for the treatment of adrenal surgical diseases in such patients.

Endocrine surgery during COVID-19 pandemic: do we need an update of indications in Italy?

The ongoing spread of the coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) poses a significant threat to global health. As the coronavirus outbreak began spreading, hospitals were forced to relocate resources to treat the growing number of COVID-19 patients. As a consequence, doctors across the country canceled tens of thousands of nonurgent surgeries. However, recognizing that the COVID-19 situation may be highly variable and fluid in different communities across the country, elective surgery could be still allowed in some centers for patients included in the high-priority class. The majority of endocrine disorders requiring surgical treatment in patients identifiable as first-priority class, or needing hospitalization within 30 days, are generally represented by malignant thyroid tumors, hyperthyroidism, hyperparathyroidism, and some adrenal disorders. The need for urgent intervention is evaluated on a case-by-case basis according to the severity of the symptoms, the likelihood of progression, and global clinical judgment. On the basis of the above indications, during the last 4 weeks, we performed 18 planned surgical treatments in patients with thyroid cancer (total thyroidectomies, plus lymph node dissection if needed) or multinodular toxic goiter. In no case, postoperative ventilatory support was needed, and the average hospital stay was 3 days. The negative COVID-19 status for all the treated patients was appropriately evaluated beforehand. Nobody knows how long the current COVID-19 pandemic will be lasting. Certainly, we will be requested in the next future to incrementally offer surgical services for endocrine disorders that have been deferred for the COVID-19 pandemic.

Open adrenalectomy: A 20-year review of our experience in a developing country.

Introduction: The aim of this study was to present our 20-year experience regarding open adrenalectomy (OA) during laparoscopic era in a developing country Turkey. Materials and Methods: A retrospective and descriptive study of patients with adrenal mass undergoing OA in the surgery department of our hospital, between January 1993 and January 2013, was carried out. All operations were performed by two surgeons. Results: Ninety patients who underwent OA in our clinic were reviewed retrospectively. The mean number of adrenal operations per month during this period was 0.38 ± 0.12. The patient included 35 men (38.8%) and 55 women (61.2%), with a mean age of 46.4 ± 17 years. The mean body mass index was 28.4 ± 5.25, and the mean American Society of Anesthesiologists score was 2.6 ± 0.57. The mean operative time was 88 ± 27 min. The mean maximum diameter of all the lesions was 4.8 ± 1.3 cm (range: 1.2-21 cm). The mean blood loss was 118 ± 23 ml during the operations. Postoperative complications were observed in four patients (5.5%). There was no mortality. The length of hospital stay was 6.2 ± 2.1 days. The most frequent type of the histological type was benign adenoma (48.8%). Conclusion: OA in a developing country is a safe method as an alternative for laparoscopic adrenalectomy which has a difficult learning curve.

Hydatid Cyst Treatment and Management in Retroperitoneal Organs; Is Percutaneous Drainage an Option?

PURPOSE: To evaluate patients who cyst hydatid (CH) in their retroperitoneal space and organs in order to determine a standard treatment option for CH. MATERIALS AND METHODS: The files of 56 patients who were treated for CH in our clinic were evaluated retrospectively. All patients underwent either percutaneous drainage (PD) or surgery. Patients were divided into two groups as PD (Group one) and surgery groups (Group two). Preoperative and postoperative results were compared statistically. RESULTS: 31 of 56 patients were male. Mean age of the patient was 39.7 (10-85). 16 patients had been treated with PD and 40 with different surgical interventions such as total cystectomy, partial cystectomy, partial nephrectomy, total nephrectomy, surrenalectomy, and laparoscopic partial surrenalectomy. Patients' followed up was 18 months (6-38m). Relapse was seen in 1 patient who underwent PD. On comparing the results, hospitalization period was prolonged in the surgical group with enlarged cyst presence. CONCLUSION: CH presence in the retroperitoneal area is rare. PD, a minimally invasive method, has the potential to be the standard treatment option as it can be performed safely in selected patients. However, currently surgical treatment is considered as the first treatment option after CH diagnosis.
