Residual adrenocortical function after bilateral adrenalectomy for pituitary-dependent Cushing's syndrome.

The incidence of residual, functioning adrenal tissue in patients treated by total bilateral adrenalectomy for Cushing's disease is not known. Between 1962 and May 1988 50 patients with Cushing's disease were treated by bilateral adrenalectomy. Of these patients, 29 underwent surgery between 1962 and 1980, when bilateral adrenalectomy was the treatment of first choice in our hospital in patients with pituitary-dependent Cushing's syndrome. In 37 patients the presence or absence of cortisol-producing tissue could be evaluated (follow-up period, median and range, 8.3 and 0.1-18.9 yr). Evidence of functioning cortisol-producing tissue (plasma cortisol level > 50 nmol/L after stopping glucocorticoid and mineralocorticoid substitution therapy for 24 h) was found in 9 patients (24%). Plasma cortisol levels in these 9 patients varied between 60 and 330 nmol/L (mean +/- SD, 180 +/- 100 nmol/L). Signs and symptoms of recurrent Cushing's syndrome were present in only 1 patient. There was no difference in plasma ACTH levels and duration of follow-up between the patients with and without evidence of functioning cortisol-producing tissue. In all 9 patients detectable aldosterone levels indicated endogenous mineralocorticoid production, whereas in only 1 patient adrenaline was detectable in the circulation. In 8 of the 9 patients suspected of functioning cortisol-producing tissue we performed a stimulation test with synthetic ACTH (1-24). In 2 patients plasma cortisol levels rose, in 6 they remained virtually unchanged. Although we found clinically relevant signs and symptoms of Cushing's syndrome in only 1 of the 50 patients, the relatively high incidence of residual, functioning adrenal tissue after "total" adrenalectomy for pituitary-dependent Cushing's syndrome necessitates continuous surveillance for recurrent Cushing's syndrome. There is no place for routine administration of full replacement doses of glucocorticoids after total adrenalectomy.

Elevated levels of adrenocorticotropin (ACTH) precursors in post-adrenalectomy Cushing's disease and their regulation by glucocorticoids.

The ACTH precursor pro-opiomelanocortin (POMC) undergoes specific endoproteolytic cleavages in the anterior pituitary gland to give ACTH-(1-39). ACTH precursors circulate in normal subjects and are high both in the ectopic ACTH syndrome and in patients with aggressive pituitary adenomas. This study examines plasma levels of ACTH precursors and ACTH in 24 patients with post-adrenalectomy Cushing's disease, in 10 of whom computed tomography showed evidence of tumor progression. ACTH precursors were higher in post-adrenalectomy Cushing's disease (median 97.5 pmol/L, range 26-647 pmol/L) than in untreated Cushing's disease (median 29 pmol/L, range 9-104 pmol/L) and normal controls (5-40 pmol/L) (P < 0.001) and were significantly higher in patients with larger tumors (median 175 pmol/L, range 52-647 pmol/L) than in the remainder (median 41 pmol/L, range 26-510 pmol/L) (P = 0.02). Surprisingly, pro-opiomelanocortin (POMC) processing to ACTH was enhanced in post-adrenalectomy patients (ratio 1 +/- 0.5) compared with Cushing's disease (5.6 +/- 0.8) and normal subjects (5.3 +/- 0.9). After hydrocortisone ACTH precursors rose in 36% of post-adrenalectomy patients (increase 15-78%) and remained within 10% of basal levels in 46%. Six patients had a rise in precursors and a fall in ACTH suggesting differential regulation of these peptides. In conclusion, whereas ACTH precursors are high in post-adrenalectomy Cushing's disease and higher levels correlate with tumor progression, processing of precursors to ACTH is enhanced.

Follow-up study on treatment in 27 patients with Cushing's disease: adrenalectomy, transsphenoidal adenomectomy and medical treatment.

27 patients with Cushing's disease were treated over a period of 18 years at the Departments of Medicine and Surgery, Nagoya University School of Medicine and the following results were obtained. 1) Adrenalectomy. 21 of 27 patients with Cushing's disease underwent adrenalectomy. 19 patients had total bilateral adrenalectomy and 2 patients unilateral adrenalectomy. 4 patients died, the cause of death not being related directly to adrenalectomy. 9 of 15 bilaterally adrenalectomized patients had hyperpigmentation even though they had been given substitution therapy with cortisol 20-30 mg daily. They had elevated plasma ACTH levels, which were not completely suppressed by 2 mg of dexamethasone or 2.5 mg of bromocriptine per day. 2) Adenomectomy, 5 patients had adenomectomy via the transsphenoidal approach. 3 patients were cured but one of them has required postoperative substitution therapy with cortisol for hypopituitarism for one year until today. 2 of 5 adenomectomized patients had a recurrence of Cushing's syndrome after remission for 6-8 months. One of these recurrent cases has been subsequently treated successfully with bromocriptine, a dopaminergic drug. 3) Medical treatment. 2.5 mg per day of bromocriptine has been effective in 2 patients without a pituitary adenoma and ineffective in the other 4 patients with a pituitary adenoma. 24 mg per day of cyproheptadine, an antiserotoninergic drug was not effective in any of the 4 patients with a pituitary adenoma.

Is unilateral adrenalectomy an alternative treatment for ACTH-independent macronodular adrenal hyperplasia?: Long-term follow-up of four cases.

OBJECTIVE: ACTH-independent macronodular adrenal hyperplasia is a rare cause of Cushing's syndrome. Bilateral adrenalectomy is considered the treatment of choice, but the patient is obliged to receive lifetime steroid replacement therapy and is susceptible to adrenal insufficiency crisis. New therapeutic alternatives are being proposed as new etiopathological features of the disease are known. Unilateral adrenalectomy of the largest gland can be a safe and effective alternative, but only short-term follow-up is reported in the literature. We present four consecutive patients with ACTH-independent macronodular hyperplasia and long-term remission of Cushing's syndrome after unilateral adrenalectomy. SUBJECTS: Four consecutive patients (two males and two females, mean age 50.3 years) with Cushing's syndrome due to ACTH-independent macronodular adrenal hyperplasia underwent unilateral adrenalectomy of the largest gland. RESULTS: The weight of the resected glands ranged from 26.8 to 210 g. Two patients suffered transient post-surgical adrenal insufficiency and had steroid replacement therapy for 60 and 14 months respectively. After a mean follow-up of 78.8 months (range 30-137 months) all the patients persist without any evidence of Cushing's syndrome. Urinary free cortisol and serum cortisol, after the adrenal insufficiency stage, have always stayed within their normal ranges, but cortisol circadian rhythm and suppressibility after dexamethasone have never normalized. No further enlargement of the contralateral gland has been documented 62 to 126 months after surgery in three of the four patients. CONCLUSIONS: Unilateral adrenalectomy can be an effective and safe alternative treatment for ACTH-independent macronodular adrenal hyperplasia, and can achieve long-term remission of Cushing's syndrome.

Outcome of bilateral adrenalectomy in congenital adrenal hyperplasia: one unit's experience.

OBJECTIVE: The use of bilateral adrenalectomy in the management of congenital adrenal hyperplasia (CAH) is controversial. We set out to review the outcome of 5 cases of CAH who have undergone adrenalectomy in our unit. DESIGN: A retrospective case note review and subject interview of the experience of adrenalectomy in the setting of a tertiary adult CAH clinic. METHODS: Subjects who had undergone adrenalectomy were reviewed at a routine clinic visit with particular reference to clinical and biochemical outcomes after adrenalectomy. RESULTS: Two subjects underwent surgery for the sole indication of desire for fertility with successful outcome and without subsequent adrenal crises. Three women suffered from the common clinical management problem of unsuppressible hyperandrogenism and worsening obesity. Whilst the outcome of improved appearance and weight loss was achieved in these subjects, all three experienced significant complications including pigmentation and acute episodes of adrenal insufficiency. CONCLUSION: We present a mean follow-up of 4.2 patient years and conclude that this procedure may be suitable for selected women with CAH. Outcomes for those pursuing fertility were positive; however, complications were noted in those women for whom the procedure was performed for symptom control. Accepting that the number of subjects is small, it is clear that more data are required before widely recommending this procedure.

Effect of adrenalectomy on cholecystokinin-8-induced Fos-like immunoreactivity in myenteric neurons and the dorsal vagal complex in rats.

OBJECTIVE: To investigate the effect of adrenalectomy on cholecystokinin-8 (CCK-8)-induced Fos-like immunoreactivity (Fos-LI) in the myenteric neurons of the dorsal vagal complex (DVC) in rats. ANIMALS: 16 male Sprague Dawley rats. PROCEDURES: Rats were allocated to 1 of 2 groups and underwent adrenalectomy or a sham adrenalectomy procedure. Rats were challenged with a supraphysiologic dose of CCK-8 (40 microg/kg) or physiologic saline (0.9% NaCl) solution (0.5 mL) administered IP; after 90 minutes, rats were euthanized, and Fos-LI was quantified in the DVC (at the levels of the area postrema, nucleus tractus solitarii, and dorsal motor nucleus of the vagus) and the myenteric neurons of the duodenum and jejunum by use of a diaminobenzidine reaction enhanced with nickel. The Fos-LI-positive cells were counted by use of an automated system and manually in the DVC and intestinal samples, respectively. Counts of Fos-LI in the different hindbrain levels and myenteric neurons were compared between the adrenalectomy--and shamtreated groups and between the CCK-8- and saline solution-treated groups. RESULTS: After adrenalectomy, CCK-8-induced Fos-LI was attenuated only in the myenteric neurons of the duodenum. CONCLUSIONS AND CLINICAL RELEVANCE: Results indicate that the adrenal gland has a role in the activation of myenteric neurons by CCK-8 in rats.

Outpatient adrenalectomy.

PURPOSE: To our knowledge we report the initial experience with outpatient, same day laparoscopic adrenalectomy. MATERIALS AND METHODS: Nine select patients were entered into our ambulatory adrenalectomy protocol. Each patient fulfilled certain preoperative and postoperative inclusion criteria, including informed consent, age 70 years or older, body mass index 40 or less, adrenal tumor less than 5 cm., no pheochromocytoma, uncomplicated laparoscopic surgery that was completed by 12 p.m., perioperative hemodynamic stability and pain control by oral analgesics. RESULTS: All 9 patients successfully underwent outpatient laparoscopic adrenalectomy. Average patient age was 53 years and average adrenal tumor size was 2 cm. Mean surgical time was 2.3 hours and mean blood loss was 53 ml. The diagnosis was aldosteroma in 7 cases, enlarging adenoma in 1 and myelolipoma in 1. Average postoperative hospital stay was 416 minutes (range 300 to 570). Postoperative analgesia comprised 6 mg. morphine sulfate and 32 mg. ketorolac. The only complication was a local abscess requiring delayed drainage at 2 weeks. No other patient was rehospitalized for any reason. A followup questionnaire survey revealed excellent patient satisfaction. CONCLUSIONS: To our knowledge we report the initial series of outpatient laparoscopic excision of a solid organ, the adrenal gland. Ambulatory adrenalectomy is feasible and safe, and results in high patient satisfaction. However, ambulatory adrenalectomy should be restricted to highly select patients and performed by minimally invasive surgeons who have considerable experience with laparoscopic adrenal surgery.

Laparoscopic partial adrenalectomy in patients with hereditary forms of pheochromocytoma.

PURPOSE: Patients with von Hippel-Lindau disease are predisposed to multiple bilateral adrenal pheochromocytoma. In these patients partial adrenalectomy may preserve adrenocortical function and avoid the morbidity associated with medical adrenal replacement. We report our experience with such cases. MATERIALS AND METHODS: Laparoscopic partial adrenalectomy was performed in patients with von Hippel-Lindau disease and pheochromocytoma when there was evidence of normal adrenocortical tissue on preoperative imaging or intraoperative examination. Suture ligature or a harmonic scalpel was used to excise the tumors, leaving a 2 to 3 mm. margin of normal tissue. RESULTS: Two patients underwent laparoscopic partial adrenalectomy and 1 laparoscopic bilateral partial adrenalectomy with preservation of normal adrenocortical tissue. Seven pheochromocytomas were removed. Laparoscopic ultrasound was essential for localizing 2 pheochromocytomas that were not visualized by the camera. Median operative time was 324 minutes, blood loss 100 cc and parenteral narcotic requirement 22 mg. morphine equivalents. No patient required hydrocortisone replacement. There has been no pheochromocytoma recurrence during short-term followup. CONCLUSIONS: Laparoscopic partial adrenalectomy is technically feasible in patients with a hereditary form of pheochromocytoma, and may preserve adrenocortical function. Laparoscopic ultrasound was necessary to identify 2 of the 7 pheochromocytomas removed.

Robotic remote laparoscopic nephrectomy and adrenalectomy: the initial experience.

PURPOSE: We evaluated the feasibility of performing laparoscopic nephrectomy and adrenalectomy exclusively by using robotic telepresent technology from a remote workstation and compared outcomes with those of conventional laparoscopy in an acute porcine model. MATERIALS AND METHODS: Five pigs underwent bilateral laparoscopic nephrectomy (robotic in 5 and conventional in 4) and adrenalectomy (robotic in 4 and conventional in 3). In the 9 robotic laparoscopic procedures all intraoperative manipulations were completely performed telerobotically from a remote workstation without any conventional laparoscopic assistance on site. Animals were sacrificed acutely. RESULTS: Robotic laparoscopic nephrectomy required significantly longer total operative (85.2 versus 38.5 minutes, p = 0.0009) and actual surgical (73.4 versus 27.5 minutes, p = 0.0002) time than conventional laparoscopy. However, blood loss and adequacy of surgical dissection were comparable in the 2 groups. Robotic laparoscopic adrenalectomy required longer total operative (51 versus 32.3 minutes, p = 0.13) and actual surgical (38.5 versus 18.7 minutes, p = 0.14) time than conventional laparoscopy. The solitary complication in this study was an inferior vena caval tear during robotic right adrenalectomy, which was adequately repaired by sutures telerobotically in a remote manner. CONCLUSIONS: To our knowledge we present the initial experience with remote telerobotic laparoscopic nephrectomy and adrenalectomy. Telepresent laparoscopic surgery is feasible.

[Transperitoneal anterior access in video-laparoscopic adrenalectomy].

BACKGROUND: The more wide spread laparoscopic technique to operate on the adrenal gland is transabdominal approach with a lateral flank adrenalectomy. However, the transabdominal anterior approach can be a sure and safe alternative in selected patients. METHODS: From 1997 to 1999, 18 selected patients underwent laparoscopic anterior adrenalectomy. Mean age was 43 years (range 25-63) with a male/female ratio of 1:1. Indications were Conn's adenoma in 10 patients, pheochromocytoma in 3 cases, Cushing syndrome in 1 and incidentaloma in 4. All the procedures were carried out laparoscopically and only one patient required conversion to an open adrenalectomy for clear signs of malignancy. The mean time for adrenalectomy was 140 minutes and the shorter times were recorded in the right-sided procedures (mean time 84 minute). Estimated blood loss was minimal and no transfusion was done. There were no postoperative complications related to the surgical technique and the hospital stay was 4 days in average. RESULTS: Our data confirm, according with other authors, that this method is feasible in selected patients. Longer times recorded for the left-sided lesions were due to the more difficult dissection required to gain the left adrenal gland. CONCLUSIONS: Transabdominal adrenalectomy with patient in the supine position is feasible, but its use is restricted to the cases with suspect bilateral or multifocal pheochromocytoma, to patients with concomitant abdominal pathologies that can be operated on laparoscopically, to surgeons who prefer to have a frontal view of the operative field.

An institutional experience with 40 first lateral transperitoneal laparoscopic adrenalectomies.

Laparoscopic adrenalectomy is gaining widespread acceptance. To evaluate this new approach, the authors evaluated 40 laparoscopic adrenalectomies. Between June 1995 and February 1999, 40 lateral transperitoneal laparoscopic adrenalectomies were performed in 38 patients. The clinical diagnoses were primary aldosteronism (20 patients), Cushing adenoma (2 patients), cortical hyperplasia with hypercortisolism (2 patients), pheochromocytoma (8 patients), and other conditions (6 patients). There were no deaths or subsequent procedures. The mean operative time was 121 minutes. One procedure performed for hypercortisolism was converted to open adrenalectomy because of hepatomegaly and postoperative adhesions. Seven patients had complications: one patient with small pulmonary embolus with transient dyspnea, one patient with pneumothorax, two patients with postoperative bleeding, two patients with prolonged pain at a trocar wound, and one patient with a urinary tract infection. Lateral transperitoneal laparoscopic adrenalectomy seems to be a safe and effective minimally invasive approach for adrenal surgery, and the authors consider it to be the standard surgical procedure for benign adrenal tumors.

Interactions between effects of adrenalectomy and diet on insulin secretion in fa/fa Zucker rats.

Our objective was to determine if a cafeteria-type diet with increased fat content would block the decrease in insulin secretion induced by adrenalectomy in obese rats. Five week old Zucker (fa/fa) rats were adrenalectomized. One week later, half of the adrenalectomized groups, and age-matched, sham-operated animals were given a diet of 16% fat and 44% carbohydrate. Control animals were maintained on standard rat chow (4.6% fat and 49% carbohydrate). After 4 weeks on the diets, in vivo measurements included caloric intake, weight gain, plasma corticosterone, triglyceride, free fatty acids, and oral glucose tolerance tests. In vitro measurements included glucose-stimulated insulin secretion, glucose phosphorylating activity, islet triglyceride content, and fatty acid oxidizing activity of cultured islets. Generally, the cafeteria diet did not block the effects of adrenalectomy on in vitro insulin secretion parameters, even though in sham-operated animals weight gain and insulin resistance was induced by the diet in vivo. Adrenalectomy and the diet exerted independent effects on glucose phosphorylation and fatty acid oxidation in islets. In conclusion, adrenalectomy decreased the elevated insulin secretion in fa/fa rats. The failure of a cafeteria diet enriched in fat to block the adrenalectomy-mediated changes in B-cell function indicates the importance of glucocorticoids and centrally-mediated effects on insulin secretion and other metabolic parameters.

Indications for adrenalectomy in the laparoscopic era.

The tilt from open to laparoscopic surgery seems to be definite in most adrenal disorders. The aim of this study is to evaluate the current indications for laparoscopy and the persistent indications for open adrenalectomy, as seen in our experience and in the literature data. Between January 1985 and December 1999, 486 patients were operated on for adrenalectomy. Since January 1994, 91 laparoscopic adrenalectomies were performed in 84 patients. The Authors retrospectively evaluated the indications for laparoscopy in 55 patients (45.9%) and for open adrenalectomy in 65 others (54.1%) operated on in the last three years. Exclusion criteria for the laparoscopic approach included clinical suspicion of malignancy and tumour size greater than 6 cm, in the 38.5% and in the 23.0% of cases respectively. In Authors experience the laparoscopic adrenalectomy is the procedure of the choice for the surgical removal of non-malignant, unilateral or bilateral tumours under 6 or 7 cm. The laparoscopy is not a radical operation for cancer. Open surgery is always indicated for large and malignant tumours. The fascinating feature of laparoscopy has not to change the indications and the surgeon must plan the appropriate approach for every single patient.

Anesthesia and laparoscopic adrenalectomy for primary aldosteronism.

Adrenalectomy is the curative treatment of primary aldosteronism or Conn's syndrome. Laparoscopic adrenalectomy, a new method, should result in less pain and shorter hospitalization. We reported 25 patients who received anesthesia and laparoscopic adrenalectomy from 1995-1999. There were 17 females and 8 males. The mean age was 41.9 years (range 25-59). Ninety-six per cent had hypertension, 76 per cent had weakness of the extremities. When these patients sought medical care, their serum potassium and bicarbonate were 2.4 and 30.9 mEq/l respectively. Before operation, after treatment with spinorolactone, they were 4.3 and 24.4 mEq/l respectively. Associated diseases and cardiovascular abnormalities were reported. General anesthesia was the anesthetic technique of choice. Laparoscopic adrenalectomy was described in detail. Sixteen patients had adenomas on the left adrenal gland, 9 were on the right. Twenty-four patients had unilateral adrenalectomy, one had enucleation of the tumor. The size of the adenoma was 1.8 cm (range 1-3). There was no morbidity or mortality. All patients were discharged on the third postoperative day.

Laparoscopic adrenalectomy: a worthwhile procedure performed in a general surgery department.

A laparoscopic procedure is considered the treatment of choice for adrenalectomy. We report the experience of a nonreferring unit for adrenal pathology; we have evaluated its safety and feasibility in a series of 40 patients. From 1994 to 2001, forty consecutive patients underwent laparoscopic adrenalectomy, 37 with transperitoneal and 3 with retroperitoneal approach. The mean operative time was 129 +/- 51.7 minutes (range 60-300): 107 +/- 29 minutes (range 60-100) for the right-sided transperitoneal adrenalectomy and 144 +/- 62 minutes (range 90-300) for the left-sided transperitoneal adrenalectomy. The mean intraoperative blood loss was 90 mL (range 40-200). The procedure laparoscopic was converted to open in one case for the presence of a voluminous angiolipoma arising from the retroperitoneal fat strictly adherent to the adrenal gland. The postoperative morbidity rate was 5.1 per cent. Pain medication was required for a mean period of 1.6 +/- 0.6 days (range 1-3). The patients were able to resume solid food after an average time of 1.8 +/- 0.7 days (range 1-4). Postoperative hospital stay was 3 +/- 1.4 days (range 2-8). We believe that laparoscopic adrenalectomy is safe and effective in removing benign functioning or nonfunctioning adrenal masses and also in a general surgery department.

Adrenalectomy for control of cancer of the breast.

Bilateral oophorectomy and adrenalectomy were used in the treatment of ten patients with advanced metastatic carcinoma of the breast, and particular attention was given to preoperative and postoperative management by a team of specialists including surgeons, endocrinologist, radiologist and pathologist. Objective and gratifying clinical remissions were achieved in three of the ten patients in this series following total oophorectomy and adrenalectomy. The remaining seven patients all subsequently died of metastatic disease. There were no operative deaths. Known cerebral or hepatic metastasis contraindicates adrenalectomy for metastatic cancer of the breast. Five of the seven patients not benefited by the operation had either cerebral or hepatic metastasis. The best candidates for adrenalectomy are premenopausal women who have previously had a clinical remission following oophorectomy and who have subsequently relapsed. The indications for adrenalectomy in the postmenopausal woman are not clear.

[Laparoscopic adrenalectomy. Results of 10 cases].

AIM OF THE STUDY: To report our experience in laparoscopic adrenalectomy and to evaluate the effectiveness of this technique for a variety of endocrine disorders. METHODS: Ten patients were operated for laparoscopic adrenalectomy between January 1998 and January 2001. RESULTS: Eight females and two men, of 45 years mean age (range, 16-71 years), were operated for laparoscopic adrenalectomy. There were 8 tumours in right adrenal gland and two in the left adrenal gland. Indications were: pheochromocytomas (n = 5), aldosterone-producing adenoma (n = 2), cortisol-producing adenoma (n = 2) and cyst (n = 1). All patients had a CT Scan or RMI preoperatively. The patients with pheochromocytoma were prepared preoperatively. Mean operative time was 133 minutes (range, 110-190 minutes). There was no mortality and morbidity was encountered in one patient (bleeding in a trocart site peroperatively). During pheochromocytoma operation, hypertension occurred in two patients. There was one conversion secondary to bleeding. The average length of stay was 3.6 days (range, 2-7 days). During follow-up (range, 6-36 months), the patients were satisfied and none had recurrence of hormonal excess. CONCLUSION: Laparoscopic adrenalectomy is safe, effective and decreases hospital stay and convalescence. The laparoscopic approach is the procedure of choice for adrenalectomy except in the case of carcinoma.

Laparoscopic approach reduces likelihood of perioperative complications in patients undergoing adrenalectomy.

Laparoscopy has been reported advantageous over the conventional open technique for adrenalectomy. However, most comparative series include the relatively more challenging cases in the open group. The aim of this study is to assess the actual role of laparoscopy in reducing perioperative complications compared to open surgery in patients undergoing adrenalectomy. Between January 1992 and December 2002, we performed 148 adrenalectomies in 138 patients. Depending on the approach, patients were divided into laparoscopic (LA) or open adrenalectomy (OA) groups. Demographics, tumor characteristics, operative data, and outcomes were analyzed. Linear and logistic regressions identified factors influencing perioperative outcomes. Multivariate-adjusted logistic regression assessed independent relationship between factors and perioperative outcomes. A total of 78 cases were performed laparoscopically and 70 open. Patients were matched for age and sex. Tumor size was smaller (3 +/- 2 vs 5 +/- 3 cm), operative time was shorter (133 +/- 65 vs 165 +/- 100 min), estimated blood loss was less (114 +/- 152 vs 350 +/- 417 cc), length of stay was shorter (3 +/- 2 vs 7 +/- 3 days), and overall complication rate was lower (7% vs 20%) in the LA compared to the OA group. The incidence of cancer in tumors > or = 6 cm (31%) was higher than in those < 6 cm (4%). All patients with cancer underwent OA. LA was the only factor independently associated with a decreased likelihood of intraoperative bleeding and postoperative pulmonary complications. Large and malignant adrenal tumors are more frequently removed through an open approach. However, this fact has no influence on the advantages of the LA over the OA. Laparoscopy reduces perioperative adrenalectomy perioperative complication rates. It has a positive impact on intraoperative bleeding and postoperative pulmonary complications.
