UNASSIGNED: Objective of this study was to assess the diagnostic efficacy of the most commonly used radiological evaluation in form of contrast enhanced computed tomography of abdomen with adrenal protocol, basic functional evaluation and surgical outcomes of primary adrenal masses.
UNASSIGNED: We have retrospectively analysed the institutional records of 108, patients admitted from August 2017 to September 2023, who had underwent surgical intervention for their adrenal mass after thorough evaluation and stabilization.
UNASSIGNED: Flank pain was the most common symptoms in 44 (40.74%) patients. Non-functional adrenal adenoma was found in 36 (33.33%) patients. Pheochromocytoma was the most the common functional adrenal mass found in 24 (22.22%) patients. CECT abdomen had suggested features of malignancy in 16(14.81%) patients. In final histopathological report 26(24.07%) patients had pheochromocytoma and 12 (11.11%) patients had adrenocortical carcinoma. CECT abdomen had sensitivity of 75%, specificity of 95.6%. Plasma free metanephrines and normetanephrine analysis had shown sensitivity of 90%, specificity of 92.86%, aldosterone to renin ratio had sensitivity of 92%, specificity of 100%. Sensitivity and specificity of the low-dose dexamethasone suppression test and plasma dehydroepiandrosterone was 100% in our study. Eighty patients (74.07%) were operated with laparoscopic adrenalectomy, 20 (18.52%) patients with open adrenalectomy. Eight patients (7.41%) were converted from laparoscopic to open. Laparoscopic approach had significantly lesser mean operating time, lesser blood loss, lesser hospitalization and lesser post-operative complications.
UNASSIGNED: Radiological analysis and functional analysis has shown good sensitivity and high specificity. Laparoscopic approach has advantage of lesser operative time, lesser hospitalization and lesser post-operative complications.

Laparoscopic adrenalectomy is worldwide currently considered the gold standard technique for patients suffering from benign lesions. There has been an increasing number of robotic-assisted adrenalectomies in the last decade due to the systematic further development of minimally invasive surgery resulting in the implementation of robot-assisted surgery. Interestingly, the available studies show some perioperative advantages for robotic surgery but overall the current evidence is weak and there are economic aspects that are not negligible. Therefore, further high-quality studies about robotic-assisted adrenalectomy are mandatory to strengthen the current evidence.
UNASSIGNED: Die laparoskopische Adrenalektomie ist bei benignen Raumforderungen der Nebenniere der therapeutische Goldstandard. Durch die stetige Weiterentwicklung der minimal-invasiven Chirurgie mit Einführung der roboterassistierten Chirurgie ist es in den letzten Jahren zu einem stetigen Anstieg robotisch assistierter Adrenalektomien gekommen. Die aktuelle Evidenzlage verspricht gewisse perioperative Vorteile für die Robotik, bei jedoch insgesamt als noch schwach zu wertender Evidenzlage und nicht zu ignorierenden ökonomischen Belastungen. Weitere qualitativ hochwertige Studien zur robotischen Adrenalektomie sind daher dringend notwendig.

BACKGROUND: Adrenalectomy for pheochromocytoma (PHEO) is challenging because of the high risk of intraoperative hemodynamic instability (HDI). This study aimed to compare the incidence and risk factors of intraoperative HDI between laparoscopic left adrenalectomy (LLA) and laparoscopic right adrenalectomy (LRA).
METHODS: We retrospectively analyzed two hundred and seventy-one patients aged > 18 years with unilateral benign PHEO of any size who underwent transperitoneal laparoscopic adrenalectomy at our hospitals between September 2016 and September 2023. Patients were divided into LRA (N = 122) and LLA (N = 149) groups. Univariate and multivariate logistic regression analyses were used to predict intraoperative HDI. In multivariate analysis for the prediction of HDI, right-sided PHEO, PHEO size, preoperative comorbidities, and preoperative systolic blood pressure were included.
RESULTS: Intraoperative HDI was significantly higher in the LRA group than in the LLA (27% vs. 9.4%, p < 0.001). In the multivariate regression analysis, right-sided tumours showed a higher risk of intraoperative HDI (odds ratio [OR] 5.625, 95% confidence interval [CI], 1.147-27.577, p = 0.033). The tumor size (OR 11.019, 95% CI 3.996-30.38, p < 0.001), presence of preoperative comorbidities [diabetes mellitus, hypertension, and coronary heart disease] (OR 7.918, 95% CI 1.323-47.412, p = 0.023), and preoperative systolic blood pressure (OR 1.265, 95% CI 1.07-1.495, p = 0.006) were associated with a higher risk of HDI in both LRA and LLA, with no superiority of one side over the other.
CONCLUSIONS: LRA was associated with a significantly higher intraoperative HDI than LLA. Right-sided PHEO was a risk factor for intraoperative HDI.

BACKGROUND: Laparoscopic adrenalectomy is widely performed for a number of hormone-producing tumors and postoperative management depends on the hormones produced. In the present study, we conducted a retrospective analysis to clarify the risk factors for postoperative complications, particularly postoperative fever after laparoscopic adrenalectomy.
METHODS: We analyzed 406 patients who underwent laparoscopic adrenalectomy at our hospital between 2003 and 2019. Postoperative fever was defined as a fever of 38 °C or higher within 72 h after surgery. We investigated the risk factors for postoperative fever after laparoscopic adrenalectomy.
RESULTS: There were 188 males (46%) and 218 females (54%) with a median age of 52 years. Among these patients, tumor pathologies included 188 primary aldosteronism (46%), 75 Cushing syndrome (18%), and 80 pheochromocytoma (20%). Postoperative fever developed in 124 of all patients (31%), 30% of those with primary aldosteronism, 53% of those with pheochromocytoma, and 8% of those with Cushing syndrome. A multivariate logistic regression analysis identified pheochromocytoma and non-Cushing syndrome as independent predictors of postoperative fever. Postoperative fever was observed in 42 out of 80 cases of pheochromocytoma (53%), which was significantly higher than in cases of non-pheochromocytoma (82/326, 25%, p < 0.01). In contrast, postoperative fever developed in 6 out of 75 cases of Cushing syndrome (8%), which was significantly lower than in cases of non-Cushing syndrome (118/331, 35.6%, p < 0.01).
CONCLUSIONS: Since postoperative fever after laparoscopic adrenalectomy is markedly affected by the hormone produced by pheochromocytoma and Cushing syndrome, it is important to carefully consider the need for treatment.

BACKGROUND: Adrenalectomy generally has favorable outcomes. It is unknown if patients with functional adrenal tumors experience different clinical outcomes than those with benign adrenal tumors, due to the presence of comorbid conditions secondary to the functional tumor. We investigated outcomes following open and laparoscopic adrenalectomy for benign nonfunctional (BNF) versus functional adrenal masses.
METHODS: Patients undergoing adrenalectomy were identified in the 2015-2020 National Surgical Quality Improvement Program database, then categorized as BNF, hyperaldosteronism, hypercortisolism, and pheochromocytoma. The primary outcome of interest was 30-d morbidity and secondary outcomes included 30-d mortality, 30-d readmission, and postoperative length of stay (LOS). Subgroup analysis was performed based upon surgical approach. Univariate analysis was performed, followed by multivariable logistic regression for individual outcomes that differed significantly between patients with BNF and functional neoplasm, factoring in patient demographics and operative approach with statistical significance on univariate analysis. Descriptive statistics and outcomes were analyzed using Pearson\'s χ2 test and Mann-Whitney U-test as appropriate.
RESULTS: There were 3291 patients with BNF while 484 had hyperaldosteronism, 263 hypercortisolism, and 46 pheochromocytomas. Within the laparoscopic group of 3615 (88.5%) of adrenalectomy patients, compared to BNF patients, patients with hyperaldosteronism had lower rates of postoperative morbidity (1.9% versus 5.2%, P < 0.001) and shorter LOS (1 d, interquartile range (IQR) [1-1] versus 1d IQR [1-2], P = 0.003); these persisted on multivariate analysis (OR 0.32, 95% confidence interval [CI] 0.14-0.74 and odds ratio 0.47, 95% CI 0.36-0.60, P < 0.001). Patients with hypercortisolism had higher morbidity (7.3% versus 5.2%, P < 0.001), 30-d readmission rates (5.3% versus 2.9%, P = 0.042) and longer LOS (2d, IQR [1-3] versus 1d, IQR [1-2, P < 0.001). On multivariate analysis, presence of hypercortisolism was independently associated with increased likelihood of readmission within 30 d (OR 2.20, 95% CI 1.11-2.99, P = 0.012) and longer LOS (>1 d) (OR 1.79, 95% CI 1.33-2.40, P < 0.001). Compared to BNF patients, patients with pheochromocytoma had higher rates of postoperative morbidity (6.2% versus 5.2%, P < 0.001). Within the open group of 469 (11.5% of adrenalectomy patients), there were no statistically significant differences in outcomes between patients with BNF and functional adrenal masses.
CONCLUSIONS: Outcomes after adrenalectomy performed for functional neoplasms differ based on surgical indication.

Introduction Advancements in radiological imaging technology have increased the discovery of adrenal incidentalomas. Large adrenal tumors (LATs) are not common, and the likelihood of malignancy increases with tumor size. LATs were defined as tumors larger than four centimeters (cm) with various pathologic diagnoses. Traditionally, open adrenalectomy was considered the gold standard for LATs, but with recent advancements in minimally invasive surgery (MIS), optimum perioperative and long-term outcomes are achievable by the MIS approach. The findings presented in this paper show that even large adrenal masses measuring up to 21 centimeters can be safely removed using a minimally invasive approach. Methodology After Institutional Review Board (IRB) approval, we reviewed medical records of adult patients who had adrenalectomies at two Saudi Arabian centers from January 2013 to February 2023. Inclusion criteria were laparoscopic or robotic adrenalectomy and adrenal lesions ≥5cm. Pediatric patients and those with open adrenalectomies were excluded. Pre-surgery, patients had imaging studies to assess mass characteristics. Pheochromocytoma patients received a 2-week adrenergic blocker treatment. Perioperative data including demographics, comorbidities, mass characteristics, surgery details, and follow-up were analyzed using SPSS-23. Patients provided informed consent and had follow-up appointments and imaging. Results Our experience involved 35 patients, 29 of whom received laparoscopic treatment and six of whom underwent robotic surgery. Of the 35 patients, more than half were females (57.1%), with a mean age of 41.7±14.9 years, the youngest and oldest participants being 16 and 73 years of age, respectively. The mean body mass index (BMI) of the participants was in the overweight range (26±6.0 kg/m2). The most common mode of presentation was incidental (42.9%), followed by hypertension (17.1%). Most patients had right-sided adrenal gland involvement (48.6%), with only four patients showing bilateral involvement. Most of the patients were classified as American Society of Anesthesiology score (ASA) 2 (40.0%) or ASA 3 (40.0%). Most of the patients were diagnosed with myelolipoma or adenoma (22.9% each) followed by pheochromocytoma (17.1%). The average estimated blood loss (EBL) was 189.3±354.6 ml for patients who underwent laparoscopic surgery and 80.0 ±34.6 ml for patients who underwent robotic surgery. The average operative room time (ORT) was 220.1±98.7 minutes (min) for laparoscopic surgery and 188.3±10.3 min for robotic surgery. One patient had to be converted from laparoscopic to open surgery due to aortic injury. The average length of stay (LOS) was 9.5±6.7 days for laparoscopic treatment and 5.5±1.9 days for robotic surgery. The mean tumor size in the greatest dimension was 8.0±4.4 cm. Only one patient who underwent unilateral laparoscopy experienced perioperative complications and converted to open surgery; nine patients who underwent unilateral laparoscopy required blood transfusion, and none of the patients who underwent robotic surgery required transfusion. None of the 35 patients experienced a recurrence of their adrenal disease during the mean follow-up period which lasted around 58 months. Conclusion MIS in Saudi Arabia is growing and is a safe method for LATs, with satisfactory surgical results compared to the traditional open surgery approach. It offers advantages in terms of EBL, complications, and disease recurrence.

Primary adrenal epithelioid sarcoma is a rare lesion of the adrenal gland, and only seven cases have been reported in the domestic and international literature to date. We herein report a case involving a 65-year-old man with primary adrenal epithelioid sarcoma. After being admitted to the hospital with an adrenal mass found on physical examination, the patient underwent laparoscopic right adrenalectomy. Postoperative pathological findings indicated an epithelioid sarcoma (proximal type). Primary adrenal epithelioid sarcoma is a rare malignancy. Diagnosis is challenging and relies on histopathology and immunohistochemical staining.

UNASSIGNED: Pheochromocytoma is a rare catecholamine-producing neuroendocrine tumor originating from the adrenal medulla chromaffin cells. Hemodynamic instability can occur during the induction of anesthesia and surgical manipulation of the tumor. This study investigated the effects of intraoperative dexmedetomidine administration on hemodynamic stability in patients undergoing laparoscopic adrenalectomy for pheochromocytoma.
UNASSIGNED: Forty patients who underwent laparoscopic adrenalectomy for pheochromocytoma were randomly assigned to the dexmedetomidine (n = 20) or control (n = 20) group. The primary outcome of this study was intraoperative hemodynamic stability, and the secondary endpoint was the plasma catecholamine concentrations, specifically of epinephrine and norepinephrine.
UNASSIGNED: The intraoperative maximum blood pressures were significantly lower in the dexmedetomidine group (control vs. dexmedetomidine group: 182 ± 31 vs. 161 ± 20, 102 ± 17 vs. 90 ± 10, and 128 ± 22 vs. 116 ± 12 [mean ± SD] mmHg and p = 0.020, 0.015, and 0.040 for systolic, diastolic, and mean blood pressure, respectively). The maximum heart rate during surgery was 108 ± 15 bpm in the control group and 95 ± 12 bpm in the dexmedetomidine group (p = 0.010). Other parameters of hemodynamic instability were comparable between both groups. Plasma catecholamine concentrations did not differ between the groups.
UNASSIGNED: Dexmedetomidine infusion following the induction of anesthesia at a rate of 0.5 μg/kg/h significantly attenuated the maximum intraoperative SBP, DBP, MBP, and HR, contributing to improved hemodynamic stability.

In this study, we investigated the outcomes of laparoscopic approaches for adrenal tumor resection in 67 patients from a single center with a median age of 51 (range 40-79). Predominantly comprising women, the majority of patients were overweight or obese. Adrenal tumors larger than 6 cm were mostly treated using the laparoscopic transperitoneal method (p < 0.001). Our results revealed that patients subjected to the retroperitoneal approach exhibited quicker recovery, as evidenced by faster resumption of oral intake and ambulation, along with reduced intraoperative blood loss and shorter hospitalization (p-value < 0.05). In contrast, patients subjected to the transperitoneal approach experienced minimal complications, though not statistically significant, despite the technique\'s intricacy and slower recovery. These findings emphasize the significance of tailoring the surgical approach to individual patient characteristics, with particular emphasis on the tumor size. The choice between the retroperitoneal and transperitoneal methods should be informed by patient-specific attributes to optimize surgical outcomes. This study underscores the need for a comprehensive evaluation of factors such as tumor characteristics and postoperative recovery when determining the most suitable laparoscopic approach for adrenal tumor resection. Ultimately, the pursuit of individualized treatment strategies will contribute to improved patient outcomes in adrenal tumor surgery.
