Laparoscopic Treatment of Adrenal Tumors: A Single-Center Experience with 58 Patients. Surg Res Pract 2016; 2016:9574391. [PMID: 27975081 PMCID: PMC5128712 DOI: 10.1155/2016/9574391] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2016] [Revised: 10/10/2016] [Accepted: 10/26/2016] [Indexed: 12/29/2022] Open
Abstract
Background. The aim of this study is to discuss the laparoscopic approach and assess the immunohistochemical expression profiles of synaptophysin, Ki-67, and inhibin and patient outcomes in adrenal masses through a series of cases treated at our institution. Method. The study was conducted on 58 patients who were diagnosed with adrenal masses. All cases were operated on laparoscopically for adrenal masses. Results. Both inhibin and synaptophysin were found positive in 45 patients (77,6%). Ki-67 was negative in 11 patients, whereas it was found positive in 42 with a rate of 1%. The size of the masses ranged from 1 up to 9 cm (mean 4,3 ± 1,5). Urine hormone excretion was measured within normal ranges in 47 out of 58 patients (81%). Most of the diagnosed patients were harboring Cortical Adenoma (n: 38; 65,5%). All of the masses were successfully resected without complication except 3 patients. Because of complications of bleeding, the operation was converted to open surgery for 2 patients. Conclusion. Morbidity, mortality, and healing were comparable, regardless of tumor size, yet involvement in both laparoscopic and adrenal surgery was required. Our results suggested that laparoscopic adrenalectomy should replace open surgery as the standard treatment for most adrenal masses.

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.

Comparison of single-surgeon series of transperitoneal laparoendoscopic single-site surgery and standard laparoscopic adrenalectomy. Urology 2012; 79:577-83. [PMID: 22386401 DOI: 10.1016/j.urology.2011.09.052] [Citation(s) in RCA: 35] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2011] [Revised: 09/12/2011] [Accepted: 09/20/2011] [Indexed: 12/13/2022]
Abstract
OBJECTIVE To assess the feasibility, safety, and efficacy of transperitoneal laparoendoscopic single-site (LESS) adrenalectomy and determine whether it shows any objective advantage compared with standard laparoscopy. METHODS From August 2009 to May 2011, 13 transperitoneal LESS adrenalectomies were performed through a 2-3-cm skin incision using the TriPort access system. This cohort was compared with a contemporary 1:2 matched-pair group of 26 patients undergoing standard laparoscopic adrenalectomy by the same urologist. The perioperative outcomes, including cosmetic satisfaction scores, were statistically analyzed. RESULTS The 2 groups were comparable with respect to patient demographics, estimated blood loss, and postoperative hospitalization (P > .05). The LESS procedures had a longer mean operative time (148.5 vs 112.9 minutes, P = .032) but a significantly lower postoperative visual analog pain scale score (2.3 vs 3.7, P = .001), fewer patients requiring analgesics (30.8% vs 73.1%, P = .011), and an earlier resumption of oral intake (21.6 vs 26.0 hours, P = .002). The mean length of the scar in the LESS group was much smaller (2.3 vs 5.9 cm, P < .0001) with a statistically significant greater mean cosmetic satisfaction score (9.5 vs 9.1, P = .042). CONCLUSION The perioperative outcomes of transperitoneal LESS adrenalectomy for small adrenal tumors were comparable to those with the standard laparoscopic approach. It also provides better postoperative pain control, faster recovery of bowel function, and better cosmetic satisfaction than standard laparoscopy, albeit with a longer operative time.

Abstract
Laparoscopic adrenalectomy is now accepted as the procedure of choice for the resection of benign adrenocortical tumours, but few studies have assessed whether the outcomes of laparoscopic adrenalectomy for adrenal phaeochromocytoma are similar to that of other adrenal tumour types. This is a retrospective cohort study. Clinical and operative data were obtained from an adrenal tumour database and hospital records. A total of 191 patients had laparoscopic adrenalectomy, of which 36 were for phaeochromocytoma, over a 12-year period. Length of hospital stay (4.8 vs 3.6 days, P= 0.03) and total operating times (183 vs 157 min, P= 0.01) were greater in the laparoscopic phaeochromocytoma resection group. Despite the greater size of the phaeochromocytomas compared to the remaining adrenal tumour types (44 mm vs 30 mm, P < 0.01), however, rate of conversion and morbidity were no different. Laparoscopic adrenalectomy for phaeochromocytoma is a safe procedure with similar outcomes to laparoscopic adrenalectomy for other adrenal tumour types.

Abstract
Laparoscopic adrenalectomy has become an accepted method for removing benign lesions of the adrenal gland. There are few contraindications to the laparoscopic approach, and the transperitoneal and retroperitoneal techniques yield excellent results. Virtually all benign lesions and select malignant lesions can be removed laparoscopically. Laparoscopic adrenalectomy has been shown to be a safe and effective approach to many forms of adrenal pathologic conditions. It should be considered the standard of care in the management of benign lesions of the adrenal gland that require surgical removal.

Abstract
PURPOSE To compare the effectiveness and efficacy of laparoscopic transperitoneal adrenalectomy (LTA) with those of open adrenalectomy (OA) in patients with pheochromocytoma. PATIENTS AND METHODS Among 24 patients (13 male, 11 female) who underwent surgical removal of pheochromocytoma, LTA and OA were performed in 15 and 9, respectively. The mean age was 45.2 years in the LTA group and 43.3 years in the OA group, and the mean tumor size was 5.2 +/- 2.0 (SE) cm and 6.4 +/- 2.6 cm, respectively. Retrospective analysis of their clinical outcomes was performed. The mean follow-up for OA and LTA groups was 36 months and 22 months, respectively. RESULTS The mean operative time was 171 +/- 66.7 minutes in the LTA group and 200 +/- 73.3 minutes in the OA group. The mean blood loss was 189.5 +/- 50.4 mL and 397.1 +/- 144.7 mL, respectively (P = 0.0341). The mean number of intraoperative hypertensive crises was 0.6 +/- 0.5 during LTA and 1.67 +/- 1.1 during OA (P = 0.0146). In the LTA group, there were no conversions to open surgery and no intraoperative complications, and the blood pressure was well managed intraoperatively without medication. The mean time to oral intake was 1.1 +/- 0.3 days after LTA and 2.6 +/- 1.3 days after OA (P = 0.0037). The mean postoperative hospital stay was 5.6 +/- 2.0 days in the LTA group and 12.4 +/- 3.5 days in the OA group (P = 0.0001). Patient-controlled analgesia was needed by 2 patients (13.3%) in the LTA group and 6 (66.7%) in the OA group (P = 0.0413). In the OA group, three pneumothoraces and one case of sepsis occurred. After a mean follow-up of 36 months, two patients in the OA group redeveloped hypertension. With a mean follow-up of 22 months, none of the 15 LTA patients redeveloped hypertension. CONCLUSIONS Laparoscopic adrenalectomy for pheochromocytoma is a safe and effective prodcedure providing the benefits of a minimally invasive approach.

Abstract
Clinically inapparent adrenal masses are incidentally detected after imaging studies conducted for reasons other than the evaluation of the adrenal glands. They have frequently been referred to as adrenal incidentalomas. In preparation for a National Institutes of Health State-of-the-Science Conference on this topic, extensive literature research, including Medline, BIOSIS, and Embase between 1966 and July 2002, as well as references of published metaanalyses and selected review articles identified more than 5400 citations. Based on 699 articles that were retrieved for further examination, we provide a comprehensive update of the diagnostic and therapeutic approaches focusing on endocrine and radiological features as well as surgical options. In addition, we present recent developments in the discovery of tumor markers, endocrine testing for subclinical disease including autonomous glucocorticoid hypersecretion and silent pheochromocytoma, novel imaging techniques, and minimally invasive surgery. Based on the statements of the conference, the available literature, and ongoing studies, our aim is to provide practical recommendations for the management of this common entity and to highlight areas for future studies and research.

Abstract
PURPOSE The authors sought to compare the outcome of children undergoing open versus laparoscopic adrenalectomy for an adrenal tumor. METHODS Medical records of children that underwent an adrenalectomy from 1990 through 1999 were reviewed. Sixty-four adrenalectomies were performed: 27 pheochromocytomas, 36 neuroblastomas, and 1 virilizing tumor. Sixty adrenalectomies were performed open and 4 laparoscopically. The patient's age, surgical length of stay, operative charge, hospital cost, operating time, blood loss, and outcome were examined. RESULTS Mean age for an open procedure was 8.9 +/- 0.9 years and 14 +/- 1.1 for laparoscopic (P =.019). Surgical length of stay for open was 5.4 +/-.38 days and 2.7 +/-.62 days for laparoscopic (P =.006). Patient operative charges were $12,941 +/- 676 for laparoscopic and $4,714 +/- 411 for open (P <.001). When total estimated patient cost, including hospital stay, were compared between groups there was no significant difference. Similar mean operating times and blood loss were noted. There were no deaths or complications in children with a pheochromocytoma. The mortality rate in children with neuroblastoma was 28%. CONCLUSIONS Adrenalectomy for benign tumors can be performed safely. In selected children a laparoscopic procedure can be expected to decrease the surgical length of stay without increasing operating time or complications.

Abstract
BACKGROUND AND PURPOSE Unilateral total adrenalectomy is the standard treatment for benign unilateral adrenal tumors. Partial adrenalectomy has to be considered for bilateral adrenal tumors. Recently, our group has reported the feasibility of unilateral and bilateral partial adrenalectomy by means of laparoscopy. Now, we present a case of recurrent pheochromocytoma after open bilateral adrenalectomy and demonstrate that laparoscopic cortex-sparing surgery is feasible for a recurrence after open surgery. CASE REPORT At the age of 10 years, a boy was found to have bilateral adrenal pheochromocytoma and was treated by open bilateral partial adrenalectomy. Eight years later, the patient presented with palpitation, sweating, and severe hypertension. Investigations biochemically and radiologically demonstrated functional recurrent pheochromocytoma in the left adrenal gland. Genetic studies confirmed mutation of the von Hippel-Lindau (VHL) gene. The patient was prepared for surgery preoperatively by phenoxybenzamine and metropolol. The surgery was performed as planned, and the normal adrenal tissue was spared. The patient had an uneventful postoperative course. His blood pressure was normal on the day of discharge. CONCLUSIONS In a specialized center with experienced laparoscopic surgeons, laparoscopic partial adrenalectomy for recurrent pheochromocytoma is feasible even after previous open surgery on the ipsilateral adrenal gland. Adrenal-sparing surgery is indicated in hereditary syndromes such as VHL and MEN II to avoid the problems of life-long steroid replacement. Recurrences have to be expected, but further surgery may be less difficult by the previous laparoscopic approach.

Abstract
This report describes a rare case of ACTH-independent macronodular adrenal hyperplasia (AIMAH) arisen with symptomatic severe hypertension and hypokaliemia. A 55-year-old man was admitted to hospital with a clinical picture characterized by several episodes of transient ischemic attacks (TIA) and right hemiplegia, related to severe arterial hypertension. Laboratory tests showed urinary levels of catecholamines, metanephrines and vanillylmandelic acid (VMA) in normal range; high urinary free cortisol excretion, elevated serum cortisol with loss of the circadian rhythm and low ACTH plasma levels. ACTH failed to respond to CRH administration. Serum cortisol levels were not modified after high doses of dexamethasone. MRI showed bilateral macronodular hyperplasia of adrenal glands, whereas pituitary-MRI did not show tumoral lesions. Therefore, ACTH-independent macronodular hyperplasia was suspected. Though obese, the patient had no typical Cushing habit, and symptomatic hypertension with hypokaliemia was the only clinical evidence for this rare kind of Cushing's syndrome. After obtaining a satisfactory control of blood pressure, the patient was successfully submitted to laparoscopic bilateral adrenalectomy and underwent complete clinical remission. The histology showed adrenal macronodular hyperplasia. During the twenty-four month follow-up, the patient had no further transient ischemic attacks or need of glucocorticoid replacement therapy and withdrew the antihypertensive drugs.

Abstract
BACKGROUND AND PURPOSE Nowadays, laparoscopy has become the approach of choice for adrenalectomy, especially in cases of benign tumors <6 cm. The authors have studied, in a retrospective trial, two groups of patients who have undergone an adrenalectomy: 10 consecutive patients operated on by an open approach and 10 consecutive patients operated on by laparoscopy. METHODS Laparoscopic adrenalectomies were performed via a transabdominal lateral approach, whereas open adrenalectomies were performed via an anterior transabdominal or posterior retroperitoneal approach. Clinical outcomes were recorded, and special attention was paid to the costs of both techniques, collecting economic data from the costs in outpatient visits, blood and urine tests, diagnostic imaging, hospital admissions prior to surgery, hospital admission for surgery, and surgical expenses. RESULTS Operative time (110 vs 123 minutes), length of postoperative stay (3.7 vs 5.8 days), and time to oral intake (1 vs 2 days) were significantly lower in the laparoscopic group. From the economic point of view, however, there were no significant differences between laparoscopic and open groups (6,306 vs 7,581), and only surgical inhospital stay costs were significantly lower in the laparoscopic series (742 vs 1,191). All the costs generated by surgery (hospital admission for surgery plus surgical expenses) were smaller in the laparoscopic group but constituted only a small part of the general expenses for these patients. The more expensive part of the budget for every patient was the hospital admissions prior to surgery for diagnosis or preoperative treatment. CONCLUSION Laparoscopy is a safe and comfortable approach for adrenalectomy and should be the technique of choice. From the economic point of view, laparoscopic adrenalectomy is cheaper than open adrenalectomy, but in all cases, surgical costs are only a minimal part of the budget, and the greater savings must come from the reduction in the presurgical diagnostic process.

Abstract
OBJECTIVE To evaluate the results of the laparoscopic technique in the treatment of adrenal pheochromocytoma. METHOD Ten patients, 7 men and 3 women, between 10 and 67 years of age (mean 48) with pheochromocytoma underwent transperitoneal laparoscopic adrenalectomy and were evaluated retrospectively, based on clinical, laboratory, and pathological diagnosis. In all cases there was a solid unilateral adrenal tumor, 5 on the left side and 5 on the right side, whose greater diameter varied from 7 to 80 mm (mean 32). Nine of the 10 patients were chronically hypertensive or had already had hypertensive crises. One patient was normotensive, but presented metabolic alterations suggestive of adrenergic hyperfunction. RESULTS No deaths occurred in this series. There were two (20%) conversions to open surgery, one due to venous bleeding and one due to the difficulty of dissection behind the vena cava in a patient presenting a partially retro-caval tumor. Surgical time in the 8 non-converted cases ranged from 70 to 215 minutes (mean 136). One patient (10%) received blood transfusion, and another (10%) presented two complications - acute renal failure and a subcutaneous infection. Both had been converted to open surgery. None of the non-converted cases was transfused or presented complications. Hospital discharge occurred between the 2nd and 11th post-operative day (mean 3). The pathological exam of the surgical specimens confirmed the diagnoses of pheochromocytoma in all 10 cases, one of them associated with an aldosterone-producing cortical tumor. CONCLUSIONS Laparoscopic adrenalectomy for selected patients presenting pheochromocytoma is feasible and provides good results.
