Abstract
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.

When a Multidisciplinary Approach Is Life-Saving: A Case Report of Cardiogenic Shock Induced by a Large Pheochromocytoma. Diseases 2022; 10:29. [PMID: 35645250 PMCID: PMC9149903 DOI: 10.3390/diseases10020029] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2022] [Revised: 05/06/2022] [Accepted: 05/11/2022] [Indexed: 02/04/2023] Open
Abstract
BACKGROUND Pheochromocytoma is known for its instantaneous presentation, especially in the younger population. Hemodynamic instability may be the cause of severe complications and impede patients' ability to undergo surgical treatment. These tumours are surgically difficult to treat due to the risk of catecholamine release during their manipulations, and when they are large, the tumour size represents an additional challenge. In our report, cardiogenic shock developed due to increases in systemic vascular resistance, and the lesion's size induced surgeons to perform open surgery. CASE PRESENTATION A 46-year-old female patient was admitted to our intensive care unit with hypertension and later cardiogenic shock. Systolic dysfunction was noted, along with severely increased systemic vascular resistance. A CT scan showed a left-sided 8.5 cm adrenal mass, which was confirmed as pheochromocytoma using meta-iodobenzylguanidine scintigraphy. Anaesthesiologists and the surgical team planned an effective strategy of treatment. Given the lesion's size and its apparent invasion of the neighbouring organs, open adrenalectomy (after prolonged hemodynamic stabilisation) was considered safer. The surgery was successful, and the patient remains free from disease two years after the initial event. CONCLUSIONS Large pheochromocytoma can be safely and effectively treated with open surgery by experienced hands but only by seeking to reach hemodynamic stabilisation and minimising the release of catecholamine before and during surgery.

Abstract
Background To describe the pathological distribution, imaging manifestations, and surgical managements and prognosis of large adrenal tumors (LATs) ≥ 5 cm Methods A total of 251 patients with LATs were analyzed on the basis of pathological or clinical diagnosis. Regarding surgery, open adrenalectomy was performed on 89 patients, and laparoscopic adrenalectomy was performed on 89 patients. Thirty-two patients with bilateral tumors were analyzed in terms of clinical characteristics. The survival rate was determined for 43 patients with adrenal metastases and 29 patients with primary adrenal malignancies. The CT characteristics including tumor diameter, shape, edge, heterogeneity, necrosis, calcification, pre-contrast attenuation, and contrast attenuation were analyzed for 117 patients. Results The majority of LATs were still benign, but they had a higher probability to be malignant. Benign LATs made up 68.13% of all cases, mainly adrenal cysts (19.52%), pheochromocytoma (18.73%), benign adenoma (16.73%), and myelolipoma (7.17%). Malignant LATs accounted for 28.69% of cases, mainly including adrenocortical carcinoma (8.76%) and metastases (17.13%). Laparoscopic surgery was found to involve less trauma than open surgery. It was also safer and postoperative recovery was faster, but it had drawbacks and could not completely replace open surgery. CT features had obvious specificity for the diagnosis of benign and malignant tumors. For example, benign adenomas had a smaller pre-contrast (< 10 Hu) whereas malignant adrenal tumors had, on the contrary, higher attenuation. Regarding adrenal malignant carcinoma, adrenal primary malignant tumors showed a better prognosis than adrenal metastases (mean survival of 19.17 months vs 9.49 months). Primary adrenal cortical carcinoma without metastasis had a better prognosis than primary adrenal cortical carcinoma metastasis (mean survival of 23.71 months vs 12.75 months), and adrenal solitary metastasis had a better prognosis than general multiple metastatic carcinoma (mean survival of 14.95 months vs 5.17 months). Conclusion LATs were more likely to be benign; however, they still had a high probability of being a malignant tumor. Understanding the clinicopathological characteristics of LATs can facilitate selection of more effective clinical treatment options.

Abstract
BACKGROUND Pheochromocytoma is well-known for sudden initial presentations, particularly in younger patients. Hemodynamic instability may cause serious complications and delay a patient's ability to undergo surgical resection. Larger tumors present a further challenge because of the risk of catecholamine release during manipulations. In the case we present, increases in systemic vascular resistance caused cardiogenic shock, and the size of the lesion prompted surgeons to veer off from their usual approach. CASE PRESENTATION A 38-year-old female patient was admitted to our intensive care unit with hypertension and later cardiogenic shock. Profound systolic dysfunction (left ventricular ejection fraction of 0.12) was noted together with severely increased systemic vascular resistance, and gradually responded to vasodilator infusion. A left-sided 11-cm adrenal mass was found with computed tomography and confirmed a pheochromocytoma with a meta-iodo-benzyl-guanidine scintigraphy. Surgical treatment was carefully planned by the endocrinologist, anesthesiologist and surgeon, and was ultimately successful. After prolonged hemodynamic stabilization, open adrenalectomy and nephrectomy were deemed safer because of lesion size and the apparent invasion of the kidney. Surgery was successful and the patient was discharged home 5 days after surgery. She is free from disease at almost 2 years from the initial event. CONCLUSIONS Large, invasive pheochromocytoma can be safely and effectively managed with open resection in experienced hands, provided all efforts are made to achieve hemodynamic stabilization and to minimize. Catecholamine release before and during surgery.

Abstract
BACKGROUND Identification of patients in whom adrenalectomy may be more difficult, can help in decision making in borderline and doubtful cases. The aim of the study was to determine patients criteria influencing difficulty of laparoscopic lateral transperitoneal adrenalectomy (LTA). MATERIAL AND METHODS The study enrolled 275 patients who underwent LTA. We analyzed the impact of gender, age, history of previous abdominal surgery, body mass index, risk of anesthesia measured as ASA scale, size, localization (left/right), and histological type of the tumor on parameters reflecting the level of difficulty of the procedure: operative time, intraoperative blood loss, conversion rate and intraoperative complications rate. RESULTS Multivariate logistic regression showed that following factors were associated with longer operative time: gender, tumor size and malignant lesions. In another model it was shown that age, size of the tumor and malignancy were associated with more excessive blood loss. Moreover, it was shown, that tumor size predictive factor for conversion. Univariate analysis showed a relation with malignancy, but multivariate analysis revealed no significance. CONCLUSIONS Patient age, gender, size and histological type of the tumor are criteria influencing parameters reflecting the level of difficulty. This criteria could be considered as predictors of the difficulty of LTA. Surgery in case of patients with combination of this risk factors should be handled by surgeon with sufficient experience to minimalize the risk of adverse events.

Abstract
BACKGROUND Laparoscopic adrenalectomy is the gold standard for treatment of benign adrenal lesions. Tumor size is a factor that might influence decision-making concerning the use of laparoscopic approach. The aim of this study was to analyze the results of adrenalectomy for tumors ≥6 cm in diameter. METHODS Two groups of patients were analyzed: first group comprised 441 patients with tumors <6 cm in diameter and second group consisted of 89 patients with tumors ≥6 cm. Both groups were compared with regard to the duration of surgery, intraoperative blood loss, conversion and complications rate. RESULTS Median duration of surgery in groups 1 and 2 amounted to 86.6 and 111.9 min (p < 0.0001), respectively. Median intraoperative blood loss in groups 1 and 2 was 56.5 and 172.8 ml (p < 0.0001), respectively. There was a linear relationship between tumor size and the duration of surgery, and between tumor size and intraoperative blood loss (p < 0.0001). There were 2 (0.5%) and 6 (6.7%) conversions in groups 1 and 2, respectively. There were 41 (9.3%) and 14 (15.7%) complications in groups 1 and 2 (p = 0.0692), respectively. CONCLUSIONS Laparoscopic adrenalectomy of tumors ≥6 cm is more difficult, but it can be regarded safe and beneficial for patients.

Abstract
Among the main benefits of laparoscopic adrenalectomy (LA) compared to open adrenalectomy (OA) the rapid recovery of patients with decreased length of stay in hospital can be highlighted. The objective of this study was to compare the open adrenalectomy with laparoscopic adrenalectomy in swine. Thirty-two swine were operated. The animals had been divided into four groups (n = 8), one group was submitted to OA and the other to LA, together with its respective control group. Parameters were evaluated regarding operative time, body temperature, hematocrit, postoperative and intraoperative complications and time to deambulation. There was no meaningful difference between operative and deambulation times, even though the latter having been higher in the group submitted to OA. The most frequent intercurrences were in bowel, damage to adrenal vessels and renal hematoma. There were no significant blood losses, and observed hypothermia did not have any clinical impact. Laparoscopy in swine experimental adrenalectomy is a reliable technique that can serve as a reference for the surgical treatment of patients with adrenal diseases with surgical indications in other animal species.

Abstract
Numerous surgical modalities are available to treat adrenal lesions. Minimally-invasive approaches for adrenalectomy are indicated in most circumstances, and new evidence continues to be accumulated. In this context, current indications for open surgical adrenalectomy (OS-A), minimally-invasive adrenalectomy (MI-A), and laparoendoscopic single-site adrenalectomy (LESS-A) remain unclear. A comprehensive English-language literature review was performed using MEDLINE/PubMED to identify articles and guidelines pertinent to the surgical management of adrenal tumors. A comprehensive chart review was performed for three illustrative cases. Clinical recommendations were generated based on relevant literature and the expertise of the investigator group. MI-A offers advantages over OS-A in properly selected patients, who experience fewer complications, lower blood loss, and shorter hospital stays. Robot-assisted laparoscopic and retroperitoneoscopic adrenalectomy may offer advantages over transperitoneal surgery, and LESS-A may be an even less-invasive option that will require further evaluation. MI-A remains the surgical treatment of choice for most adrenal lesions. Tumor size and stage are the primary indications for selecting alternative treatment modalities. OS-A remains the gold standard for large tumors (> 10 cm) and suspected or known advanced stage malignancy. LESS-A appears to be an appropriate initial approach for small tumors (< 4-5 cm), including pheochromocytoma and isolated adrenal metastases.

Abstract
BACKGROUND Laparoscopic adrenalectomy for tumors larger than 6 cm is currently a matter of controversial discussion because of difficult mobilization from surrounding organs and a possible risk of capsule rupture. MATERIALS AND METHODS Data of consecutive patients undergoing laparoscopic adrenalectomy between 1/1994 and 7/2012 were collected and analysed retrospectively. Intra- and postoperative morbidity in patients with tumors ≤6 cm (group 1, n = 227) were compared to patients with tumors >6 cm, (group 2, n = 52). RESULTS Incidence of adrenocortical carcinoma was significantly higher in group 2 patients (6.3% vs. 0.4%, P = 0.039) whereas the incidence of aldosterone-producing adenoma was lower (2% vs. 25%, P = 0.001). Mean duration of surgery was longer (105 min vs. 88 min, P = 0.03) and the estimated blood loss was higher (470 mL vs. 150 mL) in group 2 patients. Intraoperative bleeding rate (5.7% vs. 0.8%, P = 0.041), and the conversion rate were significantly higher (5.7% vs. 1.3%, P = 0.011) in group 2. Also, postoperative complication rate was significantly higher in group 2 (11.5% vs. 3.0%, P = 0.022). However, only two major complications occurred, one in each group. CONCLUSION Minimally invasive adrenal surgery can be performed by an experienced surgeon even in patients with large tumors (>6 cm) with an increased but still acceptable intra- and postoperative morbidity.

Abstract
BACKGROUND Rarely, a patient presents to a surgeon for evaluation of an adrenal incidentaloma where the final pathology is primary malignancy. For primary adrenal lymphoma, fewer than 100 cases have been reported in the literature. CASE REPORT We report a case of unilateral primary adrenal aggressive B cell lymphoma discovered incidentally in a 41-year-old female. Preoperative testing demonstrated the 6-cm mass to be biochemically silent. Subsequently, the patient underwent a laparoscopic adrenalectomy. Following pathologic diagnosis of B cell lymphoma, a metastatic workup was negative, and she underwent treatment with systemic chemotherapy. She is currently disease free 6 months postoperatively. CONCLUSION Primary adrenal lymphoma should be considered in patients with unilateral adrenal incidentaloma. We believe that adherence to guidelines of resection of incidentalomas allowed for early surgical intervention and possible cure.

Abstract
OBJECTIVES To introduce our experience in using anatomic retroperitoneoscopic adrenalectomy (ARA) for adrenal tumors >5 cm and evaluate this procedure's safety and efficiency. METHODS Of the 1400 ARAs performed in the past 8 years, 110 were performed on patients who had adrenal tumors with a diameter >5 cm. The perioperative indexes of these patients were retrospectively collected and analyzed. RESULTS The mean tumor size on postoperative pathologic examination was 7.2 ± 2.1 cm (range 5-14). Only 1 patient with right-sided adrenal pheochromocytoma (7.8 cm diameter) required conversion to open surgery owing to the tumor's severe adhesions to the liver and inferior vena cava. The mean operative time and evaluated blood loss was 70.8 ± 18.6 minutes and 81.3 ± 46.1 mL, respectively. The average postoperative interval to oral intake and drainage withdrawal was 2.1 and 2.2 days, respectively. No patient died during the operation. Major intraoperative complication (ie, injury to the vena cava) occurred in 1 patient, necessitating open surgery. Minor complications during the perioperative period occurred in 10 patients (9.1%). CONCLUSIONS When performed by experienced surgeons, ARA is a safe and feasible procedure for large adrenal masses with a diameter >7 cm; however, this procedure results in a longer operation time and greater blood loss compared with ARA performed on smaller masses. Open surgery is indicated when the tumor adheres to, or has infiltrated, the surrounding tissues.

Abstract
Results of this study suggest that laparoscopic adrenalectomy should be the treatment of choice for benign adrenal tumors. However, experience in advanced laparoscopic and open abdominal surgery is necessary in the management of large adrenal tumors. Background: Laparoscopic adrenalectomy has rapidly replaced open adrenalectomy as the procedure of choice for benign adrenal tumors. It still remains to be clarified whether the laparoscopic resection of large (≥8cm) or potentially malignant tumors is appropriate or not due to technical difficulties and concern about local recurrence. The aim of this study was to evaluate the short- and long-term outcome of 174 consecutive laparoscopic and open adrenalectomies performed in our surgical unit. Methods: Our data come from a retrospective analysis of 174 consecutive adrenalectomies performed on 166 patients from May 1997 to December 2008. Fifteen patients with tumors ≥8cm underwent laparoscopic adrenalectomy. Sixty-five patients were men and 101 were women, aged 16 years to 80 years. Nine patients underwent either synchronous or metachronous bilateral adrenalectomy. Tumor size ranged from 3.2cm to 27cm. The largest laparoscopically excised tumors were a ganglioneuroma with a mean diameter of 13cm and a myelolipoma of 14cm. Results: In 135 patients, a laparoscopic procedure was completed successfully, whereas in 14 patients the laparoscopic procedure was converted to open. Seventeen patients were treated with an open approach from the start. There were no conversions in the group of patients with tumors >8cm. Operative time for laparoscopic adrenalectomies ranged from 65 minutes to 240 minutes. In the large adrenal tumor group, operative time for laparoscopic resection ranged from 150 minutes to 240 minutes. The postoperative hospital stay for laparoscopic adrenalectomy ranged from 1 day to 2 days (mean, 1.5) and from 5 days to 20 days for patients undergoing the open or converted procedure. The mean postoperative stay was 2 days for the group with large tumors resected by laparoscopy. Conclusion: Laparoscopic resection of large (≥8cm) adrenal tumors is feasible and safe. Short- and long-term results did not differ in the 2 groups.

Abstract
The evaluation of primary hyperaldosteronism presents a challenge to endocrinologists, radiologists, and urologic surgeons. A multidisciplinary approach with biochemical screening and radiologic evaluation is essential in order to assess the nature and function of hypersecreting adrenal glands. Furthermore, it is of great importance to identify individuals that are morbidly affected by aldosterone hypersecretion. Traditionally, open adrenalectomy was the preferred option for these patients. More recently, laparoscopic adrenalectomy has offered a minimally invasive approach, with its resultant advantages of improved perioperative parameters. Herein we describe the evaluation and surgical management for patients with a suspected diagnosis of primary hyperaldosteronism.

Abstract
PURPOSE To determine the role of laparoscopy for large adrenal tumors in terms of outcomes, pathology, operative time, and morbidity. PATIENTS AND METHODS A retrospective review of 24 patients who underwent laparoscopic adrenalectomy was performed to record the size of the lesions, surgical techniques used, operative times, estimated blood loss, duration of hospital stay, need for blood transfusion, conversion to open surgery, and complications. The laparoscopic adrenalectomy patients were divided into two groups based on tumor size: <8 cm (n = 16, group 1) and >or=8 cm (n = 8, group 2). RESULTS Mean tumor size was 5.6 cm for group 1 and 12.1 cm for group 2. Mean operative times were 143.12 and 188.75 minutes for groups 1 and 2, respectively. Mean estimated blood loss was 89.69 mL for group 1 and 334.38 mL for group 2. Operative time and blood loss were significantly higher in group 2. Pathologic examination revealed eight adrenal cortical adenomas, five myolipomas, four pheochromocytomas, four cysts/pseudocysts, and three adrenocortical hyperplasias. No significant difference was found between groups concerning transfusion rates, duration of hospital stay, and conversion to open surgery. CONCLUSION Laparoscopic adrenalectomy is a feasible procedure for large masses but results in longer operative times and higher total blood loss when compared with results for masses smaller than 8 cm. Our findings suggest, however, that laparoscopic adrenalectomy for masses larger than 8 cm can produce comparable results concerning hospital stay, conversion to open surgery rate, and pathologic outcome in comparison with results for adrenal masses smaller than 8 cm.

Abstract
BACKGROUND Laparoscopic adrenalectomy (LA) is a relatively uncommon operation performed by surgeons with a specific interest in endocrine surgery as well as advanced laparoscopic surgery. LA is technically difficult and it is recommended to tackle small glands first till adequate experience is reached [1]. A minimum of 30 cases are required to master the technique [2]. The present study reviews data of 60 laparoscopic adrenalectomies comparing the later results with the first 30 cases. MATERIAL AND METHODS Starting 2001, patients diagnosed to have adrenal disorders were subjected to laparoscopic approach in a graded manner. A database was maintained with respect to age, sex, duration of symptoms, co-morbid conditions, diagnosis, size of tumor, weight of tumor, blood loss, duration of surgery, conversion to open, in-hospital stay, referral pattern, morbidity (both early and late) and mortality. The database was divided into two groups. First 30 patients constituted Group A, Group B constituted the next 30 adrenalectomies and deviation in the two was noted. Statistical analysis was performed to determine the importance of deviation of factors. RESULTS Sixty adrenalectomies were performed in 49 patients (11 being bilateral) between February 2001 and July 2008. Age group varied from 12-54 years with mean of 30.73 years, Twenty four were males. Thirty-one right and 29 left LA were performed. The comparison of factors in relation to the two groups (Group A and B respectively) revealed an increase in number of adrenalectomies performed (0.4 v/s 0.76) in relation to timeline, increased incidence of pheochromocytoma (6 v/s 18) and incidentalomas (zero v/s 8), larger tumor size (4.17 cm v/s 6.6 cm), comparable blood loss (72 cc v/s 98.3 cc) and duration of surgery (122 min v/s 112 min), increased conversion to open surgery (1 v/s 6) leading to increased in-hospital stay (2.8 days v/s 3.37 days) but a comparable morbidity (2 v/s 1) and no mortality. CONCLUSION Though technically difficult, with increasing experience and focused approach, laparoscopic skills in adrenalectomy improves. The spectrum of indications broadens, thus making laparoscopic interventions for vascular and large adrenal glands safe and patient friendly.

Abstract
BACKGROUND Cushing's syndrome (CS), due to multiple etiologies, is a disorder associated with the ravages of cortisol excess. The purpose of this review article is to provide a historical synopsis of surgery for CS, review a recent 10-year period of operative management at a tertiary care facility, and to outline a practical approach to diagnosis and management. MATERIALS AND METHODS From 1996 to 2005, 298 patients underwent 322 operative procedures for CS at Mayo Clinic, Rochester, Minnesota. A retrospective chart review was carried out. Data was gathered regarding demographics, preoperative assessment, procedures performed, and outcomes. Data are presented as counts and percentages. Five-year survival rates were calculated where applicable by the Kaplan-Meier method. Statistical analysis was carried out with SAS, version 9 (SAS Institute, Inc., Cary, NC). RESULTS Two-hundred thirty-one patients (78%) had ACTH-dependent CS and 67 patients (22%) had ACTH-independent CS. One-hundred ninety-six patients (66%) had pituitary-dependent CS and 35 patients (12%) had ectopic ACTH syndrome. Fifty-four patients (18%) had cortisol-secreting adenomas, 10 patients (3%) had cortisol-producing adrenocortical carcinomas, and 1% had other causes. Cure rates for first time pituitary operations (transsphenoidal, sublabial, and endonasal) were 80% and 55% for reoperations. Most benign adrenal processes could be managed laparoscopically. Five-year survival rates (all causes) were 90%, 51%, and 23% for adrenocortical adenomas, ectopic ACTH syndrome, and adrenocortical carcinomas, respectively. CONCLUSIONS Surgery for CS is highly successful for pituitary-dependent CS and most ACTH-independent adrenal causes. Bilateral total adrenalectomy can also provide effective palliation from the ravages of hypercortisolism in patients with ectopic ACTH syndrome and for those who have failed transsphenoidal surgery. Unfortunately, to date, adrenocortical carcinomas are rarely cured. Future successes with this disease will likely depend on a better understanding of tumor biology, more effective adjuvant therapies and earlier detection. Clearly, IPSS, advances in cross-sectional imaging, along with developments in transsphenoidal and laparoscopic surgery, have had the greatest impact on today's management of the complex patient with CS.

Abstract
OBJECTIVES To evaluate technical feasibility and analyze outcome of laparoscopic adrenalectomy (LA) for large adrenal masses more than 5 cm. METHODS The data of 22 patients (8 men, 14 women), who underwent LA for adrenal masses >5 cm between January 1995 and July 2007 were analyzed for this study. RESULTS Twenty-two patients with a mean age of 42.5 years underwent LA for large adrenal masses (>5 cm) between January 1995 and July 2007. Transperitoneal and retroperitoneal laparoscopic adrenalectomy (TPLA and RPLA) was performed in 15 and 7 patients, respectively. The mean-operative time, blood loss, tumor size and hospital stay were 149.33 and 132.1 min, 132.33 and 94.28 ml, 7.85 and 5.85 cm and 3.5 and 3.28 days, respectively. Histopathological examination of the specimen confirmed adrenal carcinoma in 5, pheochromocytoma in 14, myelolipoma in 2 and adenoma in 1 patient. Two patients of pheochromocytoma had required open conversion, one from each group (TPLA and RPLA). Three patients had postoperative complications (wound infection 1, pneumonitis with fever 1 and retroperitoneal collection 1). CONCLUSIONS The size of an adrenal mass on preoperative imaging studies alone should not be the primary factor in determining whether LA should be performed. LA for adrenocortical cancers could be performed safely and effectively in the selected group. Transperitoneal approach is most suitable and recommended for large adrenal tumor and adrenal carcinoma to employ laparoscopy. One approach (TP or RP) over the other also does not lead to the substantial benefits either to the patients or to the surgeon.

Abstract
Open adrenalectomy has been the gold-standard therapy for adrenal neoplasms. Minimally invasive treatments, however, have assumed a more central role in the management of these lesions. The traditional benefits of laparoscopy, including reduced blood loss, shorter hospital duration, and improved convalescence, extend to adrenal disease without compromising the oncologic efficacy of the surgery. Contemporary series suggest that minimally invasive surgery is also a reasonable therapeutic modality for larger adrenal masses. Laparoscopic adrenalectomy for these large masses is a technically demanding procedure that should be undertaken by experienced laparoscopic surgeons familiar with retroperitoneal anatomy and adept with vascular techniques in the event of an open conversion. Oncologic outcomes collectively suggest that in the setting of adequate surgical resection, recurrence patterns relate more to disease-process biology than surgical approach. Neither size criteria, suspicion of malignancy, nor locally invasive disease should be considered an absolute contraindication to laparoscopic adrenalectomy.

Abstract
BACKGROUND Laparoscopic adrenalectomy for small pheochromocytomas, although challenging, is widely accepted. However, its application to pheochromocytomas larger than 6 cm is questioned due to concerns of malignancy and case complexity. Our aim was to examine the impact of pheochromocytoma tumor size (>/=6 cm vs <6 cm) on operative approach and postoperative patient outcomes. METHODS A retrospective review of adrenalectomies performed at 3 university hospitals over 1 decade was analyzed. All pheochromocytomas were identified and then divided based on size into large (>/=6 cm) and small (<6 cm) groups. We examined patient and tumor demographics, pathologic diagnosis, operative approach (laparoscopic vs open), postoperative complications, and biochemical cure rates. Data were analyzed using the Student t test and Fisher exact test with a P value <.05 considered significant. RESULTS From 1995 to 2005, 65 pheochromocytomas were resected. Of the total, 38% (n = 25) tumors were >/=6 cm and 62% (n = 40) were <6 cm. For the large tumors, 1 out of 25 (4%) was malignant, whereas no small tumors were malignant. There was no statistically significant increased risk of malignancy in tumors >/=6 cm in size (P = .31). Initial operative approach was based on surgeon preference. Of the adrenalectomies performed, 88% were laparoscopic, with 3 of 25 (12%) large tumors requiring conversion from laparoscopic to open for intraoperative bleeding. None of the small tumors required conversion. No major postoperative complications (eg, stroke or myocardial infarction) occurred in either group. Minor complications (eg, wound infections and hematomas) were noted in 16% of large tumors and 12.5% of small tumors (P = .45). A total of 96% (24 of 25) patients with large tumors and 100% with small tumors showed postoperative biochemical cure. Tumor recurrence was noted in 1 patient with a tumor <6 cm. CONCLUSIONS Pheochromocytomas >/=6 cm pose a challenge for laparoscopic resection, and concerns have been raised about the validity of this operative approach. This study demonstrates that there is no significant difference in the rate of malignancy for pheochromocytomas >/=6 cm versus <6 cm. There also were no significant differences identified in complication rates, postoperative biochemical cures, or tumor recurrence rates between these groups. Laparoscopic resection of pheochromocytomas can be safely accomplished regardless of size in centers with surgeons experienced in these procedures.

Abstract
Laparoscopic adrenalectomy (LA) was first described in the literature in 1992, and has become the preferred method for the removal of benign functioning and non-functioning tumors of the adrenal gland <12 cm. The objectives of the present study are to review the experience of LA gained since it was first done in 1992 and to critically evaluate its effectiveness for the surgical management of endocrine hypertension; specifically pheochromocytoma, aldosteronoma and Cushing's syndrome and disease, as opposed to open adrenalectomy. The benefits of minimally invasive techniques for the removal of the adrenal gland include decreased requirements for analgesics, improved patient satisfaction, shorter hospital stay and recovery time when compared to open surgery. LA can be performed safely for bilateral disease and may become the standard of care for malignant tumors. Current limitations are operator-dependent and not a factor of limitations of minimally invasive techniques. A thorough pre-operative work-up is key for differentiating the various cases of hypertension and adequate pre-operative treatment is paramount when indicated.

Abstract
PURPOSE Laparoscopic adrenalectomy (LA) is controversial for large, potentially malignant tumors. We report a series of LA or hand-assisted LA for large (>5 cm) adrenal tumors. PATIENTS AND METHODS Among 210 LAs performed in 6 yr, 39 patients had potentially malignant tumors greater than 5 cm in diameter. Their perioperative and follow-up data were retrospectively analyzed. RESULTS All 39 patients had successful LAs without perioperative mortality, conversion to open surgery, or capsular disruption during dissection. The mean tumor size was 6.2 cm (range, 5-12 cm), operative time 207 min (115-315 min), and blood loss 75 ml (minimal-1400 ml). Complications included one intraoperative diaphragmatic perforation, three mild wound infections, and one pneumonia. Preoperatively there were 27 nonfunctioning tumors, seven pheochromocytomas, three cortisol-secreting tumors, and two virilizing tumors. Final pathology revealed eight malignant (four adrenocortical carcinomas and four metastatic carcinomas) and 31 benign tumors (14 cortical adenomas, eight pheochromocytomas, six myelolipomas, and three ganglioneuromas). Median follow-up was 39 months. Four patients (two adrenocortical carcinomas, one metastatic hepatoma, and one lymphoma) died 24, 10, 9, and 3 months after surgery, respectively. A hand-assisted device was used in 10 patients. Only the tumor size was larger and length of postoperative hospital stay longer for those in the hand-assisted group. CONCLUSIONS LA is a reasonable option for selected large adrenal tumors when complete resection is technically feasible and there is no evidence of local invasion. Hand-assisted LA is a good alternative to open conversion if a difficult dissection is encountered intraoperatively.

Abstract
PURPOSE OF REVIEW This review article discusses topics concerned with laparoscopic adrenalectomy for adrenal pathologies. RECENT FINDINGS Over the past decade, laparoscopic adrenalectomy has become the operation of choice for the resection of adrenal tumors, and provides dramatically reduced morbidity associated with the operation. Although current laparoscopic adrenalectomy for metastatic or primary adrenal malignancy is a feasible procedure, great care is required. Laparoscopic adrenalectomy for these adrenal pathologies should be converted to open adrenalectomy or hand-assisted laparoscopic adrenalectomy for difficult dissection, invasion, adhesions or surgeon inexperience. In general, laparoscopic adrenalectomy can be performed with acceptable outcomes in carefully selected patients with small, organ-confined, solitary adrenal metastasis or primary adrenal carcinoma. SUMMARY As surgical technique and complete resection are crucial to the success of the procedure, appropriate and careful judgment on the part of the surgeon is the most important factor in the care of a patient with such adrenal malignancies.

Abstract
BACKGROUND Laparoscopic adrenalectomy has gained acceptance in the treatment of adrenal tumors. We examine our initial 73 patients and highlight the change in patient selection and outcome that experience brings. METHODS A prospective study from 2000 to 2005 enrolled 73 consecutive laparoscopic adrenalectomy patients at the University of British Columbia and Vancouver General Hospitals. RESULTS Forty patients in an initial cohort and 33 in the follow-up group underwent adrenalectomy. The follow-up group had a greater proportion of pheochromocytomas (33.3% versus 7.5%), larger tumors (4.25 versus 1.97 cm), and higher American Society of Anesthesiologist (ASA) scores (2.82 versus 2.38) and lengths of stay (2.35 versus 1.55 days). Minor complication rates (12% versus 5%) were also higher. Operative times and blood loss were similar. Pheochromocytoma was associated with higher ASA scores and longer lengths of stay. Operative times and blood loss were not affected by diagnosis. CONCLUSIONS Increasing experience in laparoscopic adrenalectomy allows broadening of indications to include a sicker patient population.
