Objective: To explore the value of catheter-based adrenal ablation in treating Cushing's syndrome (CS)-associated hypertension. Methods: A clinical study was conducted in patients with CS, who received catheter-based adrenal ablation between March 2018 and July 2023 in Daping Hospital. Parameters monitored were blood pressure (outpatient and 24-hour ambulatory), body weight, clinical characteristics, serum cortisol and adrenocorticotropic hormone (ACTH) at 8 am, 24-hour urinary free cortisol (24 h UFC), fasting blood glucose and postoperative complications. Procedure effectiveness was defined as blood pressure returning to normal levels (systolic blood pressure<140 mmHg (1 mmHg=0.133 kPa) and diastolic blood pressure<90 mmHg), cortisol and 24 h UFC returning to normal and improvement of clinical characteristics. The parameters were monitored during follow up in the outpatient department at 1, 3, 6, and 12 months after catheter-based adrenal ablation. Results: A total of 12 patients (aged (40.0±13.2) years) were reviewed. There were 5 males, with 5 cases of adenoma and 7 with hyperplasia from imaging studies. Catheter-based adrenal ablation was successful in all without interruption or surgical conversion. No postoperative complication including bleeding, puncture site infection, adrenal artery rupture or adrenal bleeding was observed. The mean follow up was 28 months. Compared to baseline values, body weight declined to (59.48±11.65) kg from (64.81±10.75) kg (P=0.008), fasting blood glucose declined to (4.54±0.83) mmol from (5.53±0.99) mmol (P=0.044), outpatient systolic blood pressure declined to (128±21) mmHg from (140±19) mmHg (P=0.005), diastolic blood pressure declined to (78±10) mmHg from (86±11) mmHg (P=0.041), and the mean ambulatory daytime diastolic blood pressure declined to (79±12) mmHg from (89±8) mmHg (P=0.034). Catheter-based adrenal ablation in 8 patients was defined as effective with their 24 h UFC significantly reduced after the procedure (1 338.41±448.06) mmol/L from (633.66±315.94) mmol/L, P=0.011). The change of 24 h UFC between the effective treatment group and ineffective group was statistically significant (P=0.020). The postoperative systolic blood pressure in the treated adenoma group was significantly lower than those of hyperplasia group (112±13) mmHg vs. (139±20) mmHg, P=0.026). Conclusions: For patients with CS-associated hypertension who are unwilling or unable to undergo surgical treatment, catheter-based adrenal ablation could improve the blood pressure and cortisol level. Catheter-based adrenal ablation could be a safe, effective, and minimally invasive therapy. However, our results still need to be validated in further large-scale studies.

OBJECTIVE: To explore the surgical strategy and experience of reoperation for pheochromocytoma and paraganglioma which is very challenging. METHODS: The clinical data of 7 patients with pheochromocytoma and paraganglioma who underwent reoperation in Department of Urology, Peking University Third Hospital from August 2016 to February 2021 were analyzed retrospectively. There were 4 males and 3 females, with an average age of (44.1±11.5) years (28-60 years), 6 cases on the right side and 1 case on the left side. The causes of the operations included: (1) 2 cases of tumor recurrence after resection; (2) The primary operations failed to completely remove the tumors in 3 cases, because the tumors were large and closely related to blood vessels. (3) Pheochromocytoma and paraganglioma wasn't diagnosed before primary operation, therefore, drug preparation wasn't prepared. Two cases were interrupted by severe blood pressure fluctuations during the primary operations. Imaging evaluation, catecholamine biochemical examination and adequate adrenergic α receptor blockers were administrated in all the cases. The surgical approaches included open transperitoneal surgery in 4 cases, robot-assisted laparoscopy in 1 case and retroperitoneal laparoscopy in 2 cases. The innovative techniques included mobilization of the liver, inferior vena cava transection and anastomosis, and transection of left renal vein. RESULTS: The average tumor size was (8.0±3.2) cm (3.6-13.9 cm). The median interval between the reoperation and the primary operation was 9 months (IQR: 6, 19 months). The median operation time was 407 min (IQR: 114, 430 min) and the median blood loss was 1 500 mL (IQR: 20, 3 800 mL). Operations of 5 cases were performed successfully, and 1 case failed only by exploration during the operation. One case died perioperatively. There were 5 cases of intraoperative blood transfusion, the median transfusion volume of red blood cells was 800 mL (IQR: 0, 2 000 mL). One case experienced postoperative lymphorrhagia, and recovered after conservative treatment. The renal function was normal in 2 cases after resection and anastomosis of inferior vena cava or transection of left renal vein. The average postoperative hospital stay was (7.2±3.3) d (4-13 d). The median follow-up time of 6 patients was 33.5 months (IQR: 4.8, 48.0 months). The case who failed in the reoperation still survived with tumor and there was no recurrence in the rest of the patients. CONCLUSION The reoperation of pheochromocytoma and paraganglioma, which can not be resected in the primary operation or recurred postoperatively, is difficult with high risk of hemorrhage, and there is a risk of failure and perioperative death. Different surgical approaches and strategies need to be adopted based on the different situation.

A 57-year-old male patient was referred to our department with complaints of his right adrenal gland occupancy and hypertension about 6 months. When admitted to the hospital, the blood pressure was about 160/100 mmHg, and the heart rate was 110 beats/min. He was no obvious obesity, acne, abnormal mood, without weakness of limbs, acral numbness, palpitation and headache. He presented with type 2 diabetes for more than 3 years, with oral administration of metformin enteric coated tablets and subcutaneous injection of insulin glargine to control blood glucose, and satisfied with blood glucose control. Enhanced CT showed that: the right adrenal gland showed a kind of oval isodense, slightly hypodense shadow, the edge was clear, lobular change, the size was about 5.8 cm×5.4 cm, uneven density, there were nodular and strip calcification, round lipid containing area and strip low density area, and the CT value of solid part was about 34 HU. Enhanced scan showed heterogeneous nodular enhancement in the solid part of the right adrenal gland, nodular enhancement could be seen inside. The CT values of solid part in arterial phase, venous phase and delayed phase were 45 HU, 50 HU and 81 HU, respectively. Considering from the right adrenal gland, cortical cancer was more likely. No obvious abnormality was found in his endocrine examination. After adequate preoperative preparation, retroperitoneal laparoscopic adrenalectomy was performed under general anesthesia. During the operation, the 6 cm adrenal tumor was closely related to the inferior vena cava and liver, and after careful separation, the tumor was completely removed and normal adrenal tissue was preserved. The operation lasted 180 min and the blood loss was 100 mL, and the blood pressure was stable during and after the operation. There was no obvious complication. The results of pathological examinations were as follows: the size of the tumor was 7.5 cm×6.0 cm×3.5 cm, soft, with intact capsule and grayish-red cystic in section. Pathological diagnosis: (right adrenal gland) cavernous hemangioma, secondary intravascular thrombosis, old hemorrhagic infarction with calcification and ossification. After 6 months of observation, no obvious complications and tumor recurrence were found. In summary, cavernous hemangioma of adrenal gland is a rare histopathological change. Its essence is a malformed vascular mass. Blood retention is the cause of thrombosis and calcification in malformed vessels. The imaging findings were inhomogeneous enhancement of soft tissue masses, and the adrenal function examination showed no obvious abnormalities. Retroperitoneal laparoscopic surgery is feasible after adequate preoperative preparation. It is difficult to diagnose the disease preoperatively and needs to be confirmed by postoperative pathology.

We report one case of estimated glomerular filtration rate (eGFR) decline after taking unilateral adrenalectomy due to aldosterone adenoma. A 60-year-old male with 23-year history of hypertension was reported to the endocrinologist due to hypokalemia (serum potassium 3.01 mmol/L). Urine microalbumin/creatinine (ALB/CR) was 70.15 mg/g, serum creatinine was 82 μmol/L and eGFR was 89.79 mL/(min·1.73 m²). Random serum aldosterone was 172.2-203.5 ng/L, and random plasma rennin activity was 0-0.17 μg/(L·h). His captopril challenge test suggested that his aldosterone le-vels were suppressed by 8% (< 30%) and the adrenal enhanced computed tomography scan revealed a left adrenal tumor. The patient was diagnosed with primary hyperaldosteronism (PA), aldosterone adenoma and underwent left laparoscopic adrenalectomy. Histological examination confirmed adrenal cortical adenoma. One week after the operation, his serum creatinine was increased to 127 μmol/L compared with preoperative level; eGFR was 32.34 mL/(min·1.73 m²). His systolic blood pressure (SBP) was 110 mmHg and diastolic blood pressure (DBP) was 60 mmHg (hypotensive drugs discontinued), and serum potassium level was 5.22 mmol/L. At the end of the 2-year follow up, the serum creatinine of this patient remained at 109-158 μmol/L and eGFR fluctuated from 63.28-40.12 mL/(min·1.73 m²). PA is one of the most common causes of secondary hypertension. Several studies have reported renal function deterioration of PA patients after unilateral adrenalectomy, like the patient in this article. Age, preoperative plasma aldosterone concentration, albuminuria and preoperative potassium level might be significant predictors of a decrease in the eGFR. Growing evidence suggests that aldosterone could contribute to structural kidney damage, arterial injury and hemodynamic disorder. At the same time, patients with PA exhibit glomerular hyperfiltration and glomerular vascular hypertension, leading to the misinterpretation of renal function in PA patients as subtle kidney damage may be masked by the glomerular hyperfiltration before treatment. After a unilateral adrenalectomy, glomerular hyperfiltration by aldosterone excess is resolved and renal damage can be unmasked. In conclusion, kidney function deterioration after adrenalectomy can be detected in some patients with PA. Thus, accurate evaluation of kidney function in patients with PA may be essential, especially for those with preoperative risk factors for postoperative renal impairment. After unilateral adrenalectomy, close monitoring of renal function and adequate management are required for PA patients.

OBJECTIVETo investigate the efficacy of combined modality therapy for neuroblastoma in children associated with opsoclonus-myoclonus syndrome (OMS-NB).

METHODFrom May 2011 to December 2013, 6 consecutive patients (4 boys and 2 girls) diagnosed as OMS-NB underwent surgery and chemotherapy in the First Hospital, Peking University. The median age of onset was 19.5 months (range 13-24 months) and misdiagnosis occurred 7.5 months (range 2-14 months) ago. A retrospective analysis for the location, stage, pathological type, treatment way and outcome of neuroblastoma was done.

RESULT(1) All patients were misdiagnosed as simply opsoclonus-myoclonus syndrome (OMS) at the time of onset. They had been receiving treatment with adrenocorticotropic hormone and intravenous immunoglobulin within 1-13 months.OMS-NB was diagnosed by means of enhanced abdominal CT image which was delayed to be given after the poor efficacy or relapse. (2) The primary tumors were almost all small, stage I-II, located in adrenal, retroperitoneal or pelvis. The pathology of tumors included ganglioneuroblastoma (5/6) and neuroblastoma (1/6). (3) All these cases underwent surgery, 4/6 cases with complete tumor resection, 2/6 cases with tumor around the aorta and induced local residue. Preoperative and postoperative chemotherapy was given to 2 and 5 cases, respectively. (4) The patients were followed up for 3-31 months, except 1 patient lost, the other 5 are currently surviving disease-free (3 having been at the end of chemotherapy, 1 still in chemotherapy, and another had local recurrence and is receiving radiotherapy and chemotherapy after the second operation and now also stopped taking the medicine). The symptoms of nervous system have been significantly improved during postoperative chemotherapy.

CONCLUSIONTo reduce the misdiagnosis, regular CT imaging of the abdomen or pelvic should be ordered for all cases with OMS. The children with OMS-NB need to be actively treated with the combined modality therapy including surgery, chemotherapy or radiotherapy, to reduce recurrence and reduce the symptoms of nervous system.

In patients with primary aldosteronism who have bilateral adrenal incidentalomas, it is important to identify which adrenal gland is secreting excess aldosterone. Traditionally, adrenal vein sampling (AVS) has been performed for lateralization despite its invasiveness. Here we report a case of bilateral adrenal incidentaloma in which 18-Fluorodeoxyglucose (FDG)-positron emission tomography (PET) was used to identify the functional adrenal mass. A 53-yr-old man was referred to our clinic due to bilateral adrenal incidentalomas (right: 1 cm, left: 2.5 cm) on computed tomography (CT). Given his history of colon cancer, FDG-PET/CT scanning was used to rule out metastasis. Although there was focal hot uptake lesion in the right adrenal gland, the patient was suspected primary aldosteronism clinically more than metastasis because of the patient's underlying hypertension with hypokalemia. It was consistent with the results of AVS. Based on these findings, we propose that FDG-PET/CT can be used instead of AVS to identify the source of primary aldosteronism between two bilateral adrenal incidentalomas.
