Is adrenalectomy a necessary component of radical nephrectomy? UCLA experience with 511 radical nephrectomies.

PURPOSE: We determine the incidence and characteristics of adrenal involvement in localized and advanced renal cell carcinoma, and evaluate the role of adrenalectomy as part of radical nephrectomy. MATERIALS AND METHODS: The records of 511 patients undergoing radical nephrectomy with ipsilateral adrenalectomy for renal cell carcinoma at our medical center between 1986 and 1998 were reviewed. Mean patient age was 63.2 years (range 38 to 85), and 78% of the subjects were males and 22% were females. Patients were divided into subgroups of 164 with localized (stage T1-2 tumor, group 1) and 347 with advanced (stage T3-4N01M01, group 2) renal cell carcinoma. Staging of tumors was performed according to the 1997 TNM guidelines. A retrospective review of preoperative computerized tomography (CT) of the abdomen was performed. Radiographic findings were subsequently compared to postoperative histopathological findings to assess the predictive value of tumor characteristics and imaging in determining adrenal metastasis. RESULTS: Of the 511 patients 29 (5.7%) had adrenal involvement. Average size of the adrenal tumor was 3.86 cm. (standard deviation 1.89). Tumor stage correlated with probability of adrenal spread, with T4, T3 and T1-2 tumors accounting for 40%, 7.8% and 0.6% of cases, respectively. Upper pole intrarenal renal cell carcinoma most likely to spread was local extension to the adrenal glands, representing 58.6% of adrenal involvement. In contrast, multifocal, lower pole and mid region renal cell carcinoma tumors metastasized hematogenously, representing 32%, 7% and 4% of adrenal metastasis, respectively. The relationship between intrarenal tumor size (mean 8.9 cm., range 3 to 17) and adrenal involvement (independent of stage) was not statistically significant. Renal vein thrombus involvement was demonstrated in 8 of 12 cases (67%) with left and 2 of 9 (22%) with right adrenal involvement. Preoperative CT demonstrated 99.6% specificity, 99.4% negative predictive value, 89.6% sensitivity and 92.8% positive predictive value for adrenal involvement by renal cell carcinoma. CONCLUSIONS: With a low incidence of 0.6%, adrenal involvement is not likely in patients with localized, early stage renal cell carcinoma and adrenalectomy is unnecessary, particularly when CT is negative. In contrast, the 8.1% incidence of adrenal involvement with advanced renal cell carcinoma supports the need for adrenalectomy. Careful review of preoperative imaging is required to determine the need for adrenalectomy in patients at increased risk with high stage lesions, renal vein thrombus and upper pole or multifocal intrarenal tumors. With a negative predictive value of 99.4%, negative CT should decrease the need for adrenalectomy. In contrast, positive findings are less reliable given the relatively lower positive predictive value of this imaging modality. Although such positive findings may raise suspicion of adrenal involvement, they may not necessarily indicate adrenalectomy given the low incidence, unless renal cell carcinoma with risk factors, such as high stage, upper pole location, multifocality and renal vein thrombus, is present.

Primary hyperaldosteronism in the era of laparoscopic adrenalectomy.

Laparoscopic adrenalectomy has been recommended as the standard method for removing an aldosteronoma. To assess our surgical experience with primary hyperaldosteronism in the era of laparoscopic adrenalectomy a 6-year retrospective review of 30 consecutive patients was done. The 20 men and 10 women ranged in age from 35 to 78 with a mean of 51.2 years. All patients were hypertensive and hypokalemic with a mean serum potassium of 2.9 +/- 0.32 (standard deviation) mmol/L. Serum aldosterone was elevated in 28 of 30 (94%) patients and normal in the remaining two. Serum renin was suppressed in all patients. CT correctly localized the tumor in all 30 patients. Twenty-eight patients had histologically documented adenomas and two had associated cortical hyperplasia on pathology. Mean adenoma size was 2.0 +/- 1.12 cm. Twenty-four patients underwent left laparoscopic adrenalectomies, whereas right laparoscopic adrenalectomies were performed in five. One was converted to an open left adrenalectomy. Mean operative time was 183 minutes. The mean hospital stay for laparoscopic adrenalectomy was 2.2 days. The patients were followed from one to 63 months (mean 26.1 months). Twenty-nine of 30 (95%) patients were rendered normokalemic. The remaining patient takes a potassium-wasting diuretic. Persistent hypertension was present in 10 of 30 (33%) patients. Blood pressure in nine of 10 patients was controlled with less medical therapy. The other patient's blood pressure remained difficult to control despite multiple medications. Duration of hypertension before surgery was a significant risk factor for persistent hypertension (P < 0.05). Gender (P > 0.05) and age (P > 0.05) at the time of surgery were not statistically significant predicators for persistent hypertension. There were two reported trocar site hernias. We conclude that primary hyperaldosteronism due to aldosterone-producing tumors can be diagnosed and accurately localized with preoperative measurements of serum aldosterone, renin, and CT scanning. Laparoscopic adrenalectomy is safe and effective for the treatment of primary hyperaldosteronism with minimal associated morbidity and a short hospital stay. Hypokalemia may be cured by surgical treatment, although persistent hypertension still occurs. Duration of hypertension before surgery is a risk factor for persistent hypertension whereas age and sex are not.

[The effect of adrenalectomy on morphine dependence behavior of rats with forced-swimming].

In this study, the possible action of stress and glucocorticoids on the drug-seeking behavior was explored in the rats with morphine dependence. Forty rats were assigned into four groups randomly and received different treatments as follows: adrenalectomy; adrenalectomy + hydrocortisone 20 mg/kg S.C.; adrenalectomy + hydrocortisone 40 mg/kg S.C.; saline S.C.; The effect of adrenalectomy and hydrocortisone on morphine conditioned place preference (CPP) in rats with forced-swimming was observed. The results showed: 1. there was no significant difference for the adrenalectomized rats' spending time between the morphine and saline-paired side during the test session (t = 1.84, P > 0.05), but obvious differences of time spent between the morphine and saline-paired side were observed among the other three groups (P < 0.05 or P < 0.01); 2. the time spent in the morphine-paired side of the adrenalectomized group significantly decreased, compared with those of the other three groups, and there was no difference for the time spent in the morphine-paired side among the groups of adrenalectomy + hydrocortisone 20 mg/kg S.C., adrenalectomy + hydrocortisone 40 mg/kg S.C., and saline S.C.. These data suggested that adrenalectomy could decrease the facilitation action of morphine CPP induced by forced swimming in rats, whereas administration with glucocorticoids should reverse this effect.

Laparoscopic adrenalectomy: pathologic features determine outcome.

INTRODUCTION: The differential outcomes of laparoscopic adrenalectomy are not well described. Therefore, we evaluated these outcomes in the 3 groups most often seen clinically: bilateral adrenalectomy for Cushing's disease (group 1), pheochromocytoma (group 2) and unilateral adrenalectomy for non-pheochromocytoma (group 3). METHODS: We reviewed a longitudinal database of 72 consecutive cases of laparoscopic adrenalectomy carried out between 1997 and 2001 at the Centre for Minimally Invasive Surgery, University of Toronto. RESULTS: Patients in group 1 tended to be older (median 49 yr) and heavier (median 87 kg). They had a longer operating time (median 255 min), more postoperative complications (15%) and a longer median postoperative stay (4 d). Patients in group 2 had intermediate outcomes: a median operating time of 198 minutes, complication rate of 8.3% and a median postoperative hospital stay of 3 days. However, they had more intraoperative blood loss (median 150 mL). Group 3 patients had the best outcomes with the shortest median operating time (125 min), least blood loss (median 50 mL), fewer complications (6%) and shortest hospital stay (median 2 d). CONCLUSIONS: Although the outcomes of laparoscopic adrenalectomy are uniformly good, on the basis of the underlying pathologic characteristics, patients can be divided into groups that have different expected outcomes. Patients requiring a unilateral adrenalectomy except for pheochromocytoma have the best recorded outcomes. Surgeons transferring to laparoscopic adrenalectomy would benefit from selecting patients in this group during their learning curve.

[Laparoscopic adrenalectomy: Akita University experience].

We performed 52 laparoscopic adrenalectomies between January 1997 and March 2003. In 51 patients, adrenal tumors were successfully removed laparoscopically. In one patient, the laparoscopic procedure was converted to open surgery because of insufflator's trouble and hemorrhage. Perioperative blood transfusion was required in two patients; one for intraoperative and another for postoperative bleeding. We compared laparoscopic adrenalectomy with conventional open surgery which had been performed in our clinic before the laparoscopic adrenalectomy era. The mean operative time of the laparoscopic adrenalectomy (187 +/- 59 min) was not significantly longer than that of the open surgery (193 +/- 49 min). The mean estimated blood loss of laparoscopic adrenalectomy (75 +/- 145 g) was significantly less than that of the open surgery (438 +/- 447 g). Time to oral intake and ambulation for laparoscopic adrenalectomy were significantly earlier than those of the open surgery. Operation time was significantly shortened as the experience of this surgery was accumulated. The results of our experience support the concept that laparoscopic adrenalectomy is safe and is a standard treatment for surgical treatment of adrenal tumors.

[Morbidity of unilateral and bilateral laparoscopic adrenalectomy according to the indication. Report of a series of 100 consecutive cases].

INTRODUCTION: Laparoscopic adrenalectomy is the reference technique for the treatment of adrenal tumours. This retrospective study reports the experience of 100 consecutive laparoscopic adrenalectomies, in order to assess its indications, the incision, the morbidity and to determine the limitations of this procedure. MATERIAL AND METHODS: Between April 1994 and June 2004, 100 laparoscopic adrenalectomies were performed in 92 patients via a transperitoneal (n = 93) or retroperitoneal (n = 7) approach, with 84 unilateral and 8 bilateral adrenalectomies. The mean age was 52 years. The operative and postoperative characteristics and the functional results were evaluated. RESULTS: The mean operating time was 112 min [70-175] via the retroperitoneal approach, 101 min [40-215] via the transperitoneal approach, and 135 min [120-270] for bilateral adrenalectomies. The mean tumour diameter was 44 mm [10-120 mm]. The mean blood loss was 215 ml [0-1210 ml]. Ten patients were transfused. The mean hospital stay was 3 days. Histology revealed 25 Conn adenomas, 20 cortisol-secreting adenomas and Cushing syndrome, 22 phaeochromocytomas, 20 metastases, 2 adrenal cortical adenomas, and 11 incidentalomas. Conversion to "open" surgery were necessary for technical difficulties in 6% of cases. There were 7 minor postoperative complications (7%) and 4 late complications (4%) (deep vein thrombosis, effusion, 2 local recurrences). Four patients in the group with secondary adrenal tumours were alive without recurrence 18, 20, 44 and 48 months after adrenalectomy. Antihypertensive treatment was stopped in 16 of the 25 patients operated for Conn adenoma. The mean follow-up was 31 months [5-98 months]. CONCLUSION: This technique has a low morbidity, requires minimal postoperative analgesia and a short hospitalisation. The retroperitoneal or transperitoneal approach must be chosen as a function of the patient's history and the surgeon's habits. Tumours larger than 8 cm can be resected, but with a higher morbidity. Laparoscopic adrenalectomy for malignant tumours is associated with higher morbidity.

Laparoscopic adrenalectomy.

Advances in minimally invasive surgery have made it possible to remove solid organs such as the adrenal gland laparoscopically. Several studies have shown that when applied to appropriate operative candidates, laparoscopic adrenalectomy is a safe alternative to conventional open surgery with real advantages in terms of decreasing postoperative pain and length of hospital stay and allowing earlier return to normal activity. The indications for laparoscopic adrenalectomy are essentially the same as those described for open adrenalectomy. We do not recommend laparoscopic adrenalectomy for known primary or metastatic malignant tumors of the adrenal glands, because of the risk of tumor implantation that might compromise the patient's chance for cure, nor do we recommend it for lesions larger than 6 to 8 cm where the chance of malignancy is high. The preoperative preparation, laparoscopic instruments, operative techniques, and potential complications and their treatments are described in this review. Laparoscopic adrenalectomy is becoming the preferred method of surgically treating many adrenal problems. Although conventional surgical approaches will undoubtedly be required to treat certain adrenal lesions, surgeons with an interest in treating patients with adrenal disorders must become proficient in the technique of laparoscopic adrenalectomy. This will allow them to select the most appropriate operative approach for their patients' individual problems.

Electron microscopic analysis of adrenalectomy-induced hippocampal granule cell degeneration in the rat: apoptosis in the adult central nervous system.

As described in the preceding paper, adrenalectomy triggers hippocampal granule cell degeneration that begins within days after adrenalectomy, continues for months, and is the only apparent cell death anywhere within the brain. At the light microscopic level, granule cell degeneration is characterized by coalescing of nuclear chromatin into numerous spherical bodies. Since the morphology at the light microscopic level resembled the nuclear morphology characteristic of "apoptosis" rather than "necrosis," we undertook this ultrastructural study to determine if adrenalectomy induces the morphological features characteristic of apoptosis. Electron microscopy revealed coalescing of nuclear chromatin, compaction of cytoplasm, and the budding-off of cytoplasmic bodies that were engulfed by glia. Mitochondria, the Golgi apparatus, and rough endoplasmic reticulum appeared relatively normal early in the process of granule cell degeneration when nuclear changes were prominent. Presynaptic terminals innervating degenerating granule cells appeared normal. Electron-dense degeneration of granule cell axon terminals in association with normal postsynaptic elements of CA3 pyramidal cells highlighted the extraordinary selectivity of adrenalectomy-induced granule cell death. Ten weeks after adrenalectomy, astrocytes were filled with abnormally abundant glial fibrils and neuronal debris. This "apoptotic" morphology produced by adrenalectomy was clearly distinct from the "necrotic" granule cell morphology produced by intrahippocampal injection of the neurotoxin volkensin. These results indicate that, in a manner possibly analogous to castration-induced prostate cell death, loss of adrenal hormone triggers a process in dentate granule cells that causes the morphological changes characteristic of "apoptosis." Thus, adrenal steroids may be obligatory growth factors for dentate granule cells and their loss may initiate a selective process in the mature brain that is unique or that may normally occur only in the developing brain.

Could aminoglutethimide replace adrenalectomy?

Could aminoglutethimide replace adrenalectomy? This question has already been answered in clinical practice in the United Kingdom, for surgical adrenalectomy has declined markedly in frequency as new hormonal therapy has appeared. An optimal assessment of an endocrine therapy can only be made in previously untreated patients because of the heterogeneity of previously treated populations. Thus aminoglutethimide (AG) and adrenalectomy have been compared for previously untreated and treated populations. Because AG is commonly called 'medical adrenalectomy', this article will review and compare aminoglutethimide therapy with surgical adrenalectomy and make the case that surgical adrenalectomy is no longer indicated in the management of breast cancer.

Laparoscopic adrenalectomy in pheochromocytomas.

BACKGROUND: The aim of this study was to evaluate 17 patients undergoing laparoscopic adrenalectomy for the treatment of pheochromocytoma by transperitoneal anterior approach. METHODS: Seventeen patients underwent laparoscopic adrenalectomy for pheochromocytoma between January 1994 and May 2002. Ten females (58.8%) and 7 males (41.2%) were operated on; 14 patients (82.3%) had sporadic pheochromocytoma and 3 (17.7%) were familiar cases. Mean age was 42 yr (range 25-72 yr). All patients were treated pre-operatively with alpha-blockers. Seven patients (41.2%) underwent right adrenalectomy; 9 (52.9%) underwent left adrenalectomy and 1 (5.9%) bilateral adrenalectomy. RESULTS: No conversion to open surgery occurred and no mortality was observed. The right-side adrenalectomy required a mean operative time of 86 min (range 45-120), the left-side procedure a mean operative time of 116 min (range 80-140) and the bilateral one 219 min. In two patients (11.8%), a laparoscopic cholecystectomy and ovariectomy, respectively, were performed without changing the position of the patient on the operating table. Only 1 patient (5.9%) presented significant intraoperative hypertension, and arrhythmia resolved by medical therapy. No other intraoperative and post-operative complications were reported. Mean hospital stay was 3 days (range 2-8 days). At mean follow-up of 48 months (range 6-96 months), regression of symptoms and control of blood pressure were obtained without additional treatment in all patients. No recurrences were reported. CONCLUSION: In our experience, adrenal pheochromocytoma can be treated safely and effectively by laparoscopic transperitoneal anterior approach.

[The necessity for perioperative cortisol substitution. Spontaneous and stimulated ACTH and cortisol secretion during unilateral adrenalectomy for renal cell carcinoma].

UNLABELLED: Impaired adrenal function during perioperative stress carries the risk of acute cortisol (Cs) deficiency (Addisonian crisis), which may be critical without Cs supplementation. Thus, with evidence of dysfunction of the adrenal glands perioperative substitution is indicated. However, it is unclear whether unilateral adrenalectomy may attenuate the adrenocorticoid response. Glucocorticosteroids are potent agents with several well-known side effects. The purpose of the present study was to evaluate if routine Cs supplementation is justified and necessary in patients undergoing adrenalectomy during nephrectomy for renal-cell cancer. METHODS: Ten consecutive patients with renal-cell cancer (5 male, 5 female; age 58 +/- 10 years; ASA class I-II) who underwent adrenalectomy with radical nephrectomy were included in this study. None of them had received steroids for at least 5 years prior to the current surgery. Anaesthesia was induced with propofol, fentanyl, and vecuronium and maintained with isoflurane (PetIso: 0.8 +/- 0.3 vol.%) in nitrous oxide (66%) and oxygen. The patients did not receive any Cs treatment perioperatively. Monitoring included heart rate (beats/min), mean arterial pressure (mm Hg), central venous pressure (mm Hg), O2 saturation (%), and body temperature (degrees C, rectal). Plasma analyses included Cs (Cs radioimmunoassay IBL; normal 120-250 ng/ml), adrenocorticotropic hormone (ACTH) (ACTH-II IRMA; normal (10-50 pg/ml), glucose, and electrolytes determined as follows: preoperatively (8 a.m.); 1-6 h (60-min intervals) after surgery; pre-corticotropin-releasing hormone (CRH) (Corticobiss: 2 micrograms/kg i.v.) administration (1st postop. day at 8 a.m. and after 30, 60, 90, and 120 min. The study was completed with plasma analyses on postoperative days 2 and 3 (8 a.m.). RESULTS: None of the patients showed any clinical signs of plasma parameter of adrenal insufficiency due to the unilateral adrenalectomy. Serum levels (median: 25%/75% percentiles) of Cs (maximum [max.]:253 [217/288] ng/ml) and ACTH (max.:347 ([68/405] pg/ml) were elevated above the normal range postoperatively). After intravenous stimulation with CRH (1st postoperative day), Cs (max.:273 [248/310] ng/ml) and ACTH (max.: 107 ([75/275] pg/ml) were also increased above normal. During postoperative days 2 and 3 (8 a.m.) Cs and ACTH remained in the high-normal range. CONCLUSIONS: Data from this study indicate that unilateral adrenalectomy was associated with adequate spontaneous Cs secretion by the remaining adrenal gland. Moreover, stimulation with CRH demonstrated adequate reactivity of the pituitary-adrenal axis. None of the patients showed any signs of Cs deficiency by clinical or serum parameters. Therefore, we do not recommend routine Cs supplementation in patients undergoing adrenalectomy during tumor nephrectomy, nevertheless, Cs supplementation remains necessary for patients with primary hypothalamic-pituitary-adrenal dysfunction (Addison's disease) or hyperfunction (Cushing's disease).

[Subtotal bilateral adrenalectomy preserving adrenocortical function].

This study analyzed the frequency of recurrence and postoperative adrenocortical function in 16 patients who had been operated on by bilateral subtotal adrenalectomy since 1995. Bilateral pheochromocytoma was found in 13 patients, bilateral adrenal metastases in 2 patients, and bilateral micronodular adrenocortical hyperplasia with primary aldosteronism in 1 patient. An endoscopic approach was performed in four patients. The remaining 12 patients were operated on by an open approach. In ten patients, unilateral subtotal adrenalectomy with contralateral total adrenalectomy (synchronous or metachronous) was performed. Six patients underwent bilateral subtotal adrenalectomy. In all patients, a total of residual adrenal tissue of at least 1/3 of a normal adrenal gland was left in situ. 15 patients were successfully weaned from exogenous steroid substitution. During a mean follow-up period of 24 months, no recurrences were observed. Three patients died without local recurrence. The present study provided evidence for the safety and benefit of subtotal bilateral adrenalectomy, which could guarantee sufficient adrenocortical function in adrenal remnant volume of more than one-third of one adrenal gland even after dividing the main adrenal vein. At our institution, particularly in patients with inherited pheochromocytoma, subtotal adrenalectomy has become a common surgical strategy.

Posterior retroperitoneoscopic adrenalectomy: lessons learned within five years.

Posterior retroperitoneoscopic adrenalectomy is one of the new endoscopic methods in endocrine surgery. In a prospective clinical study 142 posterior retroperitoneoscopic adrenalectomies (72 right, 70 left) were performed in 130 patients (52 males, 78 females, age 49.1 +/- 14.9 years). Indications were primary adrenal tumors (unilateral, n = 118; bilateral, n = 2), adrenal metastases (n = 2), and bilateral ACTH-dependent hyperplasias (n = 10). Tumor size ranged from 0.5 to 7.0 cm (mean 2.7 +/- 1.4 cm). Partial adrenalectomies were performed in 39 patients. Conversion to open posterior adrenalectomy was necessary in five patients and seven procedures (5%). Intraoperative and postoperative complications were minor and occurred in 5% and 13%, respectively. Mortality was zero. Operating time was 101 +/- 39 minutes (range 35-285 minutes) and depended on tumor type (pheochromocytoma versus others; p < 0.01), tumor size (< 3 vs. > or = 3 cm; p < 0.05), gender (p < 0.05), and extent of resection (partial versus complete, p < 0.05. Twenty-three adrenalectomies (17%) were performed within 1 hour or less. Blood loss was 54 +/- 72 ml. Consumption of analgesics was low (mean 6 mg piritramide postoperatively). Median duration of hospitalization was 3 days. Posterior retroperitoneoscopic adrenalectomy is a safe method that has become a standard procedure in endocrine surgery.

Bilateral adrenalectomy for ectopic Cushing's syndrome-discussions on technique and indication.

BACKGROUND: Tumors producing adrenocorticotropic hormone (ACTH) or corticotropin releasing hormone (CRH) often remain undiagnosed until severe Cushing's syndrome appears, and it may be difficult to distinguish from Cushing's syndrome due to pituitary tumors. Many patients suffer from disease spread, with metastases in the liver or other locations, and the main symptoms may be mineral disturbances, diabetes mellitus, or psychological symptoms from the severe hypercortisolism. Bilateral adrenalectomy may alleviate this situation, but is sometimes a troublesome procedure in these severely ill patients. METHODS: We have retrospectively investigated 8 patients with ectopic Cushing's syndrome who have undergone bilateral adrenalectomy at the University Hospital in Uppsala. In addition, another 5 patients who underwent bilateral adrenalectomy for other reasons (recurrent pituitary Mb Cushing or bilateral hyperplasia) were scrutinized for technical considerations. Indications, timing of surgery, and operative procedures were studied to identify signs that may support our approach to management in the future. RESULTS: Curative surgery was not possible in any of the cases with ectopic Cushing's syndrome. Of the 13 operated patients, handport-assisted laparoscopic adrenalectomy was successfully performed bilaterally in 5 patients and unilaterally in combination with contralateral open surgery in 1 patient; conventional open surgery was performed on 7 patients, 3 of which were conversions from intitial handport-assisted procedures. Non-fatal complications occurred in 4 out of 10 patients. CONCLUSIONS: We conclude that bilateral handport-assisted laparoscopic adrenalectomy is safe, and that all surgical techniques in these severely ill patients may be troublesome and technically demanding. Early surgical intervention may reduce the technical disadvantages. Moreover, bilateral adrenalectomy can substantially reduce the symptoms of Cushing's syndrome, although effects on mortality are not obvious.

Adrenalectomy for treatment of Cushing syndrome: results in 122 patients and long-term follow-up studies.

Patients with Cushing syndrome (n = 122) who underwent adrenalectomy from 1957 through 1993 were reviewed for survival and complications. Of the 122 patients, 70 had adrenocortical adenoma, 30 Cushing's disease, 6 primary pigmented nodular adrenocortical disease (PPNAD), 7 other types of primary nodular hyperplasia, 5 adrenocortical carcinoma, and 4 ectopic ACTH syndrome. Sixty-five patients with adrenocortical adenoma are alive, and the survival rate was equal to the age-matched control population, when patients who died of the postoperative complication were excluded. Of the patients with Cushing's disease, 20 are alive; and 10 of 16 patients (63%) who were followed-up and evaluated had skin pigmentation. Four of sixteen patients (25%) developed Nelson's syndrome. Four PPNAD patients and five with other types of nodular hyperplasia are alive. Most of these patients underwent bilateral total adrenalectomy, but some patients remitted after unilateral adrenalectomy. All of five adrenocortical carcinoma patients and four with ectopic ACTH syndrome died within 2 years after operation. The prognosis for patients with adrenocortical adenoma after unilateral adrenalectomy is excellent, though it is important to avoid operative complications. The rapid cure of signs and symptoms of glucocorticoid excess after total adrenalectomy is ensured, and prognosis is satisfactory under careful glucocorticoid replacement, making total adrenalectomy an alternative treatment for Cushing's disease.

Synchronous bilateral endoscopic adrenalectomy: experiences after 18 operations.

BACKGROUND: Patients who undergo unilateral adrenalectomy are known to benefit from the endoscopic procedure. Only a few reports on bilateral endoscopic adrenalectomy exist. The optimal approach and the value of this operation were assessed in this study. METHODS: For 18 patients, synchronous bilateral lateral adrenalectomy with intraoperative repositioning was performed for different indications. The transperitoneal and retroperitoneal approaches were varied on both sides. RESULTS: With the reported procedure, the operative time diminished considerably. Blood loss was low, and no blood transfusions were required. No conversion to an open procedure was necessary. There were no intraoperative or postoperative complications, except for one death from pulmonary embolism. The mean postoperative hospital stay was 7 days, and the follow-up evaluation showed overall improvement. CONCLUSION: The risk associated with endoscopic bilateral adrenalectomy is low. Transperitoneal and retroperitoneal lateral adrenalectomy are recommended as approaches of choice. The authors advocate early bilateral adrenalectomy for Cushing's disease after unsuccessful transsphenoidal operation and ectopic adrenocorticotropic hormone production from an inaccessible tumour.

Laparoscopic telementored adrenalectomy: the Italian experience.

BACKGROUND: Laparoscopy is widely accepted as the gold standard for adrenalectomy. Telementoring has been developed to reduce the complications associated with surgeon inexperience. We report our preliminary experience with laparoscopic telementored adrenalectomy. METHODS: From July 2002 to May 2003, eight laparoscopic telementored adrenalectomies were performed between two separate operating sites 430 km apart. Six of these procedures were monolateral laparoscopic adrenalectomies, and one was bilateral. All cases were performed by an expert open surgeon who was skilled in laparoscopic procedure but who had no experience in laparascopic adrenalectomy RESULTS: All the procedures were successfully performed in a telementored fashion. The mean operative times, blood loss, and postoperative morbidity results were comparable to those for standard laparoscopic adrenalectomies reported in the literature. CONCLUSIONS: This preliminary experience has demonstrated the feasibility of national telementoring. It is a viable method that can potentially add to surgical education and decrease the likelihood of complications due to inexperience with new techniques.

Laparoscopic partial adrenalectomy.

BACKGROUND: Most laparoscopic adrenalectomies involve total removal of the whole adrenal gland, and reports of laparoscopic partial adrenalectomies have been very few. The criteria for performing a laparoscopic partial adrenalectomy have not been described. METHODS: (a) Patients with functioning adrenal tumors smaller than 3 cm in diameter were selected. (b) The solitary adrenal tumors were evaluated by preoperative thin-slice computed tomography (CT) scan. (c) Solitary lesions were reconfirmed with intraoperative ultrasonography. (d) Partial adrenalectomy was performed with at least a 5-mm margin using a vascular stapler. RESULTS: Laparoscopic partial adrenalectomy was performed in five patients using the vascular stapler. Hemostasis was perfect in all five patients. The tumor was located in the inferior part of the right adrenal gland in three cases and in the upper pole of the left adrenal gland in two cases. The postoperation pathologic diagnosis was adrenocortical adenoma in all five patients, and excessive hormonal levels or symptoms all disappeared. CONCLUSIONS: Laparoscopic partial adrenalectomy can be performed safely using a vascular stapler.
