Hemal AK, Singh A, Gupta NP. Whether adrenal mass more than 5 cm can pose problem in laparoscopic adrenalectomy? An evaluation of 22 patients. World J Urol 2008; 26:505-8.

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
PURPOSE OF REVIEW Laparoscopic adrenalectomy for malignant adrenal masses has been controversial because of initial reports of high rates of local recurrence and carcinomatosis. With additional experience, improved outcomes have been reported. We evaluate the contemporary role of laparoscopy in treating adrenal malignancies. RECENT FINDINGS Several contemporary reports now demonstrate that laparoscopic adrenalectomy for primary adrenal malignancy can provide oncologic outcomes equivalent to open surgery without an increased risk of carcinomatosis or port site recurrence. Although long-term survival of 47 months with no recurrence has been reported, the underlying aggressiveness of this tumor has contributed to a 39.6% rate of recurrence for the 48 contemporary cases reviewed in this article. This compares favorably to open series that report a similar or higher recurrence rate. When utilized for the treatment of solitary metastases to the adrenal gland, laparoscopic adrenalectomy provides equivalent oncologic outcomes to open adrenalectomy. SUMMARY Laparoscopic adrenalectomy for malignancy can be performed in appropriately selected cases with equal oncologic outcomes to open approaches while providing advantages in patient morbidity. Caution must be taken to avoid tumor entry or spillage because of the potential for local recurrence, port site recurrence, and carcinomatosis that can occur with these aggressive tumors.

Abstract
PURPOSE To investigate the three-dimensional movement of internal fiducial markers near the adrenal tumors using a real-time tumor-tracking radiotherapy (RTRT) system and to examine the feasibility of high-dose hypofractionated radiotherapy for the adrenal tumors. MATERIALS AND METHODS The subjects considered in this study were 10 markers of the 9 patients treated with RTRT. A total of 72 days in the prone position and 61 treatment days in the supine position for nine of the 10 markers were analyzed. All but one patient were prescribed 48 Gy in eight fractions at the isocenter. RESULTS The average absolute amplitude of the marker movement in the prone position was 6.1+/-4.4 mm (range 2.3-14.4), 11.1+/-7.1 mm (3.5-25.2), and 7.0+/-3.5 mm (3.9-12.5) in the left-right (LR), craniocaudal (CC), and anterior-posterior (AP) directions, respectively. The average absolute amplitude in the supine position was 3.4+/-2.9 mm (0.6-9.1), 9.9+/-9.8 mm (1.1-27.1), and 5.4+/-5.2 mm (1.7-26.6) in the LR, CC, and AP directions, respectively. Of the eight markers, which were examined in both the prone and supine positions, there was no significant difference in the average absolute amplitude between the two positions. No symptomatic adverse effects were observed within the median follow-up period of 16 months (range 5-21 months). The actuarial freedom-from-local-progression rate was 100% at 12 months. CONCLUSIONS Three-dimensional motion of a fiducial marker near the adrenal tumors was detected. Hypofractionated RTRT for adrenal tumors was feasible for patients with metastatic tumors.

Abstract
OBJECTIVES To examine the impact of adrenal tumor size on perioperative morbidity and postoperative outcomes in patients undergoing laparoscopic adrenalectomy. METHODS A total of 227 laparoscopic adrenalectomies were divided in three groups according to size as estimated by pathologic specimen maximum diameter: less than 6 cm (group 1, n = 140), between 6 and 7.9 cm (group 2, n = 47), and equal to or larger than 8 cm (group 3, n = 40). We prospectively recorded and analyzed clinical and pathologic data. RESULTS Average operative time was 60 minutes (range, 50 to 90 minutes) for group 1, 75 minutes (range, 65 to 105 minutes) for group 2, and 80 minutes (range, 65 to 120 minutes) for group 3. Estimated blood loss, median (interquartile range) was 50 mL (range, 20 to 100 mL), 100 mL (range, 48 to 225 mL), and 100 mL (range, 50 to 475 mL) for groups 1, 2, and 3, respectively. We observed a total of 10, 4, and 4 complications in groups 1, 2, and 3, respectively. Average hospital stay was 2 days (range, 2 to 3 days), 2 days (range, 2 to 3 days), and 3 days (range, 2 to 4 days), respectively, for groups 1, 2, and 3. Operative time, average blood loss, and mean hospital stay were significantly higher (P <or=0.05) for group 3 compared with group 1. CONCLUSIONS Laparoscopic adrenalectomy in large adrenal masses (8 cm or greater) is associated with significantly longer operative time, increased blood loss, and longer hospital stay, without affecting perioperative morbidity.

Abstract
BACKGROUND Laparoscopic adrenalectomy (LA) has become the gold standard treatment for small (less than 6 cm) adrenal masses. However, the role of LA for large-volume (more than 6 cm) masses has not been well defined. Our aim was to evaluate, retrospectively, the outcome of LA for adrenal lesions larger than 7 cm. PATIENTS AND METHODS 18 consecutive laparoscopic adrenalectomies were performed from 1996 to 2005 on patients with adrenal lesions larger than 7 cm. RESULTS The mean tumor size was 8.3 cm (range 7-13 cm), the mean operative time was 137 min, the mean blood loss was 182 mL (range 100-550 mL), the rate of intraoperative complications was 16%, and in three cases we switched from laparoscopic procedure to open surgery. CONCLUSIONS LA for adrenal masses larger than 7 cm is a safe and feasible technique, offering successful outcome in terms of intraoperative and postoperative morbidity, hospital stay and cosmesis for patients; it seems to replicate open surgical oncological principles demonstrating similar outcomes as survival rate and recurrence rate, when adrenal cortical carcinoma were treated. The main contraindication for this approach is the evidence, radiologically and intraoperatively, of local infiltration of periadrenal tissue.

Abstract
The case of a patient with bilateral adrenal metastases from lung cancer is described. A left open adrenalectomy at the time of the lung resection had a long-term curative effect. Several months later a right laparoscopic adrenalectomy was performed, but 2 months later a loco-regional recurrence with a port-site metastasis was diagnosed on the right side. Open adrenalectomy, by avoiding the potential for port-site metastasis, may be oncologically superior to laparoscopic adrenalectomy in this situation.

Abstract
OBJECTIVES To present our experience in laparoscopic adrenalectomy for isolated adrenal metastasis. METHODS A total of 34 adrenalectomies were performed in 32 patients for incidental adrenal masses discovered at primary tumor diagnosis or during follow-up. The primary tumors diagnosed were 13 cases of lung carcinoma, 9 of renal cell carcinoma, 2 of colorectal carcinoma, 2 of bladder carcinoma, and 1 each of ovarian carcinoma, breast cancer, gastric cancer, and melanoma. Two patients had no history of a primary tumor. The mean patient age was 59 years (range 26 to 75). The male/female ratio was 1.9:1. RESULTS The mean operative time was 87 minutes (range 40 to 240). The average blood loss was 89 mL (range 0 to 1000). No conversions to open surgery were needed. The mean hospital stay was 3 days (range 1 to 5). One intraoperative diaphragmatic lesion developed that was repaired laparoscopically, and 1 patient had a pancreatic fistula that was managed by percutaneous drainage. The mean tumor size was 4.3 cm (range 1.5 to 9). The microscopic analysis revealed 22 malign lesions (64.7%) and 12 cases of benign pathologic features (35.3%). The mean survival time was 26 months (range 4 to 64) for the 22 patients with malign lesions. In 2 patients (9.1%), the surgical margins were positive. CONCLUSIONS Laparoscopic adrenalectomy for small isolated metastases is feasible. However, because of the high risk of positive margins, this procedure should only be done by expert laparoscopists. We did not find a correlation between mass size and malignancy. Nevertheless, we believe that longer follow-up is mandatory before definitive conclusions can be drawn.

Abstract
PURPOSE To our knowledge we introduce the technique of anatomical retroperitoneoscopic adrenalectomy. MATERIALS AND METHODS From February 2000 to October 2005 anatomical retroperitoneoscopic adrenalectomy was performed in 800 consecutive patients with adrenal lesions using a 3 port lateral retroperitoneal approach. After incising Gerota's fascia 3 relatively bloodless planes were entered consecutively to expose and separate the adrenal gland. When entering the first dissection plane between the perirenal fat and anterior renal fascia located at the superomedial side of the kidney, the adrenal could be identified at the initial stage of the operation. The following dissections proceeded in the plane between the posterior renal fascia and the lateral aspect of perirenal fat, and then in the avascular plane located on the parenchymal surface of the upper renal pole. The adrenal vein was dealt with at the final stage. Operative time was defined as the time from skin incision to skin closure. RESULTS Mean +/- SE operative time was 45 +/- 19.1 minutes (range 25 to 230) and mean estimated blood loss was 25 +/- 10.6 ml (range 5 to 200). Average time to oral intake and ambulation were 1.2 and 1.0 day, respectively. Minor postoperative complications occurred in 12 patients (1.5%). Major complications and perioperative mortality were not observed. The procedures resulted in marked clinical improvements in patients with a hormone secreting tumor, except in 6 with idiopathic adrenal hyperplasia. CONCLUSIONS Anatomical retroperitoneoscopic adrenalectomy is a safe, effective, technically efficient procedure for surgical adrenal diseases.

Abstract
BACKGROUND While open adrenalectomy is often performed for malignant adrenal tumors, increasing numbers of surgeons have adopted the laparoscopic approach. The postoperative benefits of laparoscopic adrenalectomy are well established, but questions persist about long-term oncologic outcomes when used for malignant lesions. The current study was undertaken to compare laparoscopic with open adrenalectomy for isolated adrenal metastases. METHODS From March 1993 to April 2006, 20 adults underwent adrenalectomy for isolated metastases to the adrenal gland. Three patients were excluded because of a concomitant nephrectomy (2) and an unresectable tumor (1). Patient demographics, tumor characteristics, and oncologic outcomes of the remaining patients were reviewed and analyzed. RESULTS Of the 17 patients who received adrenalectomy for an isolated metastasis, there were 11 men and 6 women with a mean age of 58 +/- 3 y. Nine patients underwent laparoscopic adrenalectomy, and 8 patients had open adrenalectomy. Laparoscopic adrenalectomy was associated with less blood loss (63 +/- 8 mL versus 2207 +/- 1067 mL, P=0.05), a lower complication rate (0% versus 63%, P=0.009), and a shorter length of stay (2.4 +/- 0.6 d versus 5.4 +/- 0.7 d, P=0.02). With a follow-up of up to 97 mo, there were no port site metastases, no tumor recurrences, and no difference in survival between laparoscopic and open adrenalectomy (median 19 months versus 17 months, 5-year survival 34% versus 54%, P=0.96). CONCLUSIONS When not limited by tumor size or invasion of surrounding tissue, laparoscopic adrenalectomy is a safe alternative to open adrenalectomy with equivalent oncologic outcomes and clear postoperative benefit for patients with isolated metastases to the adrenal gland.

Abstract
INTRODUCTION The accidental discovery of an adrenal mass called incidentaloma has become an increasingly frequent clinical problem with the question of a correct and appropriate therapeutic approach being the subject of controversial discussions. MATERIALS AND METHODS Clinical charts of 52 patients (22 male, 30 female) who underwent adrenalectomy for an incidentaloma at our institution between 1987 and 2001 were reviewed. RESULTS Median age was 56.4 years. Reasons for surgery were unclear significance in 22 patients, suspicion of malignancy in 5, increase in size in 8, maximum tumor diameter of more than 5 cm in 7, fear of malignancy in 1, and subclinical secretion of cortisol in 5 patients. No data were available for 4 patients. Surgical resection was performed using a conventional transabdominal approach in 28 patients, a conventional dorsal approach in 17 patients, and an endoscopic retroperitoneal approach in 7 patients. Histopathologic examination ruled out adrenal adenoma in 32 patients, adrenal myelolipoma in 12, unilateral nodular hyperplasia in 4, cystic lesion in 3, and adrenocortical carcinoma in 1 patient. The mean size of all lesions was 5.5 cm. Evaluating the criteria for surgical treatment regarding age of the patients and size of the lesions, 25 patients (48%), including the patient with the adrenocortical carcinoma, were younger than 60 years and had an adrenal lesion exceeding 4 cm in size. During postoperative follow-up that was available for 39 patients, 3 developed contralateral tumors that were treated by resection in 1 and by close follow-up in 2. CONCLUSIONS Size should not be the sole criterion; treatment should be tailored to the individual patient. Especially in patients younger than 60 years with an adrenal lesion exceeding 4 cm in size, an adrenalectomy, predominantly via an endoscopic approach, should be carried out, because a repeated and life-long close follow-up of an anxious patient who has been informed of the diagnosis will in some cases exceed the cost of a single endoscopic operation.

Abstract
Laparoscopic urology has evolved considerably during last decade as well as number and spectrum of surgical related complications. Experiences reported by laparoscopic trained groups allow preventing, promptly recognizing, and safe and efficient management of the laparoscopic related complications. We present our complications in all patients undergoing urological laparoscopic procedures from November 1992 to June 2005. A literature search was conduced to evaluate complications of every laparoscopic procedure.

Abstract
INTRODUCTION We aimed to compare the outcomes of laparoscopic and open adrenalectomies and to assess the impact of the availability of advanced laparoscopy on adrenal surgery at our institution. MATERIALS AND METHODS A retrospective analysis of data of all patients who underwent adrenalectomy at the University of Massachusetts Medical Center over a 10-year period. RESULTS Sixty-four consecutive patients underwent adrenalectomy during the study periods. There were 19 open (OA) and 45 laparoscopic (LA) adrenalectomies performed. There was no significant difference between the average size of adrenal masses removed for the LA and the OA groups [4.3 vs. 5.5 cm, respectively (P=0.23)]. LA proved superior to OA, resulting in shorter operative times (171 vs. 229 min, P=0.02), less blood loss (96 vs. 371 mL, P<0.01), shorter time to regular diet (1.9 vs. 4.4 d, P<0.001), and shorter hospital stay (2.5 vs. 5.8 d, P=0.02). In addition, the average annual number of adrenalectomies increased significantly since the establishment of our advanced laparoscopic program (10.0 vs. 2.0, P=0.02). CONCLUSIONS LA offers superior results when compared to OA in terms of operative time, blood loss, return of bowel function, duration of hospital stay, and functional recovery. The availability of advanced laparoscopy has resulted in a significant increase in the number of adrenalectomies performed at our institution without a shift in surgical indications.

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
AIM Laparoscopic adrenalectomy is currently indicated for biochemically and clinically functional adrenal tumors and potentially malignant tumors of the adrenal glands. Non-functional adenomas greater than 5 cm in diameter of the adrenal gland are generally considered to represent potentially malignant tumors. The present study shows indications of laparoscopic adrenalectomy for non-functional adrenal tumors with hypertension in a retrospective fashion. METHODS Between 1994 and 2004, 110 laparoscopic adrenalectomies were performed at Tokushima University Hospital. All 110 patients underwent detailed endocrinological examination before surgery. Medical and operative records of these 110 patients (57 men, 53 women), including operative parameters, histopathological findings and pre- and postoperative hypertension, were reviewed. Forty-five patients underwent laparoscopic adrenalectomy for non-functional adrenal tumors, and [(131)I]6beta-iodomethyl-19-norcholest-5(10)-en-3beta-ol (NP-59) scintigraphy was performed for patients with preoperative hypertension. RESULTS Mean patient age was 55.0 years (range, 22-77 years). Mean maximum tumor diameter was 42 mm (range, 20-105 mm). All adrenal tumors were removed successfully by laparoscopic surgery. Hypertension was postoperatively improved in seven of the 11 patients with preoperative hypertension, without subclinical Cushing syndrome. Importantly, all patients who improved hypertension after adrenalectomy displayed strong accumulation in adrenal tumors with visualization of the contralateral gland on NP-59 scintigraphy. Conversely, blood pressure did not improve in four patients for whom scintigraphy yielded negative results. CONCLUSIONS The indication of laparoscopic adrenalectomy for non-functional adrenal tumors is generally considered for lesions more than 5 cm diameter. However, the present study suggests that laparoscopic surgery should be considered even in patients with tumors less than 5 cm in diameter, if both hypertension and accumulation in tumors on NP-59 scintigraphy are present.

Abstract
CONTEXT Adrenocortical carcinoma (ACC) is a rare and heterogeneous malignancy with incompletely understood pathogenesis and poor prognosis. Patients present with hormone excess (e.g. virilization, Cushing's syndrome) or a local mass effect (median tumor size at diagnosis > 10 cm). This paper reviews current diagnostic and therapeutic strategies in ACC. EVIDENCE ACQUISITION Original articles and reviews were identified using a PubMed search strategy (http://www.ncbi.nlm.nih.gov/entrez/query.fcgi) covering the time period up until November 2005. The following search terms were used in varying combinations: adrenal, adrenocortical, cancer, carcinoma, tumor, diagnosis, imaging, treatment, radiotherapy, mitotane, cytotoxic, surgery. EVIDENCE SYNTHESIS Tumors typically appear inhomogeneous in both computerized tomography and magnetic resonance imaging with necroses and irregular borders and differ from benign adenomas by their low fat content. Hormonal analysis reveals evidence of steroid hormone secretion by the tumor in the majority of cases, even in seemingly hormonally inactive lesions. Histopathology is crucial for the diagnosis of malignancy and may also provide important prognostic information. In stages I-III open surgery by an expert surgeon aiming at an R0 resection is the treatment of choice. Local recurrence is frequent, particularly after violation of the tumor capsule. Surgery also plays a role in local tumor recurrence and metastatic disease. In patients not amenable to surgery, mitotane (alone or in combination with cytotoxic drugs) remains the treatment of choice. Monitoring of drug levels (therapeutic range 14-20 mg/liter) is mandatory for optimum results. In advanced disease, the most promising therapeutic options (etoposide, doxorubicin, cisplatin plus mitotane, and streptozotocin plus mitotane) are currently being compared in an international phase III trial (www.firm-act.org). Adjuvant treatment options after complete tumor removal (e.g. mitotane, radiotherapy) are urgently needed because postoperative disease-free survival at 5 yr is only around 30%, but options have still not been convincingly established. National registries, international cooperations, and trials provide important new structures for patients but also for researchers aiming at systematic and continuous progress in ACC. However, future advances in the management of ACC will mainly depend on a better understanding of the molecular pathogenesis facilitating the use of modern cancer treatments (e.g. tyrosine kinase inhibitors).

Abstract
OBJECTIVES To compare our experience with synchronous bilateral adrenalectomy using laparoscopic and open techniques. Laparoscopic adrenalectomy has become the reference standard for management of benign unilateral adrenal pathologic findings. METHODS This was a nonrandomized retrospective chart review of 12 known patients who underwent simultaneous bilateral adrenalectomy, comparing five laparoscopic and seven open procedures. One urologic surgeon performed all laparoscopic cases, and one general surgeon performed all open procedures. RESULTS All patients had Cushing's disease or syndrome. The average patient age was 47.4 years (range 24 to 71) and 42.4 years (range 19 to 70), with an average body mass index of 38.2 kg/m2 and 36.0 kg/m2 for the laparoscopic and open groups, respectively. The operating time was on average 60 minutes longer for the laparoscopic group. No open conversions were necessary. The median blood loss (100 versus 500 mL, P < 0.01) and hematocrit drop (8.5% versus 12.6%, P = 0.05) were lower for the laparoscopic group. The transfusion rates and hospital stay trended lower in the laparoscopic group (20% versus 57% and 3 versus 8.5 days, respectively). Specimen weights for both the right and left glands trended larger for the laparoscopic group. The complication rates were similar between groups at 60% for the laparoscopic versus 71% for the open groups. CONCLUSIONS Simultaneous laparoscopic bilateral adrenalectomy is safe and effective. Compared with the open approach, it resulted in decreased blood loss, lower transfusion rate, and a trend toward a shorter hospital stay, although the operating time was longer. The laparoscopic approach should be the treatment of choice for bilateral adrenalectomy.

Abstract
The laparoscopic approach to the adrenal gland has evolved to be the gold standard for most cases of adrenal conditions requiring surgical treatment. There is general consent about the safety, efficacy, and reproducibility of laparoscopic adrenal surgery. Compared to the open surgery, significant advantages with regard to shorter hospitalization time, decreased postoperative morbidity, improved cosmetics, and quicker convalescence are evident. The anatomic location of the adrenal gland led to the development of various approaches, including lateral transperitoneal, anterior transperitoneal, lateral retroperitoneal, posterior retroperitoneal, and even transthoracic approaches. The lateral transperitoneal approach is the technique most frequently used for laparoscopic adrenalectomy. A large operative field provides good orientation and visualization of familiar landmarks known from open surgery. In particular in the early learning curve this represents an advantage of the transperitoneal laparoscopic approach. This article describes in detail the indications, contraindications, preoperative evaluation, surgical technique, management of intraoperative complications, and outcome after lateral transperitoneal adrenalectomy.

Abstract
OBJECTIVE We report our experience in laparoscopic adrenalectomy, after adopting the laparoscopic technique for 10 years as a primary option for suprarenal surgery. METHODS We included 200 laparoscopic adrenal surgeries performed consecutively in 183 patients with surgical adrenal pathology between November 1994 and November 2005. Sixty-seven (36.6%) patients were male and 116 (63.4%) were female, with an average age of 49.1 years (age range 8 months to 78 years). RESULTS The most frequents clinical diagnosis were hyperaldosteronism (17.5%), metastatic cancer (15.8%), pheochromocytoma (15.3%), Cushing syndrome (7.1%), adrenal cyst (4.9%) and myelolipoma (2.7%). A total of 164 total adrenalectomies, 29 partial adrenalectomies and 7 marsupializations of adrenal cysts were performed. Mean surgical time was 82.6 minutes (range 25 to 240 minutes) and mean hospitalization time was 2.5 days (range 1-10 days). The size of the suprarenal gland and/or tumor varied between 1 and 14 cm (average 5.6 cm). The rate of complication was 6%. In 8 of the patients, there was another laparoscopic procedure besides the adrenal surgery: cholecystectomies (2), marsupialization of a renal cyst (2), block nephrectomy (2), partial nephrectomy for a tumor (1) and pancreatic cystectomy (1). One patient underwent a right laparoscopic adrenalectomy and an ipsilateral percutaneous nephrolithotomy. CONCLUSION The accumulated experience with 200 laparoscopic adrenal procedures has allowed the management of endocrine pathologies, such as, aldosteroma, pheochromocytoma, Cushing syndrome and rare entities, such as, cysts, myelolipomas in a suitable manner. Additionally, it has permitted us to extend the benefits of a minimally invasive procedure for large adrenal masses and selected oncology cases.

Abstract
BACKGROUND Laparoscopic adrenalectomy is an attractive alternative to open surgery, but making the transition can be difficult. AIM To evaluate the initial experience of a general surgical team at a single institution at making the transition. METHODS The details of 15 patients undergoing laparoscopic adrenalectomy were prospectively recorded over a 21-month period. RESULTS Fifteen glands were removed from fifteen patients. Nine of these were left-sided. The mean gland size was 3.4 cm. Pathology included six non-functioning adenomas, four Conn's syndrome, two Cushing's syndrome and three phaeochromocytomas. Mean operating time was 74 minutes (range 31-172 minutes), with one conversion to open procedure. There were no morbidities and no mortality. CONCLUSION Our initial experience demonstrates this approach to be the ideal technique for removal of benign adrenal tumours with significant advantages for the patient.

Abstract
PURPOSE We report a prospective, randomized comparison of transperitoneal laparoscopic adrenalectomy (TLA) vs retroperitoneal laparoscopic adrenalectomy (RLA) for adrenal lesions with long-term followup. MATERIALS AND METHODS Between December 1997 and November 1999, 57 consecutive eligible patients with surgical adrenal disease were prospectively randomized to undergo TLA (25) or RLA (32). Study exclusion criteria were patient age greater than 80 years, body mass index greater than 40, bilateral adrenalectomy and significant prior abdominal surgery in the quadrant of interest. Mean followup was 5.96 years in the 2 groups. RESULTS The groups were matched in regard to patient age (p = 0.84), body mass index (p = 0.43), American Society of Anesthesiologists class (p = 0.81) and laterality (p = 0.12). Median adrenal mass size was 2.7 cm (range 1 to 9) in the TLA group and 2.6 cm (range 0.5 to 6) in the RLA group (p = 0.83). TLA was comparable to RLA in terms of operative time (130 vs 126.5 minutes, p = 0.64), estimated blood loss (p = 0.92), specimen weight (p = 0.81), analgesic requirements (p = 0.25), hospital stay (p = 0.56) and the complication rate (p = 0.58). One case per group was electively converted to open surgery. Pathology data on the intact extracted specimens were similar between the groups. Averaged convalescence was 4.7 weeks in the TLA group and 2.3 weeks in the RLA group (p = 0.02). During a mean followup of 6 years 2 patients in the TLA group had a late complication (port site hernia). Mortality occurred in 5 patients, including 1 with TLA and 4 with RLA, during the 6-year followup. CONCLUSIONS For most benign adrenal lesions requiring surgery laparoscopic adrenalectomy can be performed safely and effectively by the transperitoneal or the retroperitoneal approach.

Abstract
Phaeochromocytomas are rare neuroendocrine tumours with a highly variable clinical presentation but most commonly presenting with episodes of headaches, sweating, palpitations, and hypertension. The serious and potentially lethal cardiovascular complications of these tumours are due to the potent effects of secreted catecholamines. Biochemical testing for phaeochromocytoma is indicated not only in symptomatic patients, but also in patients with adrenal incidentalomas or identified genetic predispositions (eg, multiple endocrine neoplasia type 2, von Hippel-Lindau syndrome, neurofibromatosis type 1, and mutations of the succinate dehydrogenase genes). Imaging techniques such as CT or MRI and functional ligands such as (123)I-MIBG are used to localise biochemically proven tumours. After the use of appropriate preoperative treatment to block the effects of secreted catecholamines, laparoscopic tumour removal is the preferred procedure. If removal of phaeochromocytoma is timely, prognosis is excellent. However, prognosis is poor in patients with metastases, which especially occur in patients with large, extra-adrenal tumours.

Abstract
PURPOSE Laparoscopic surgery has become a standard method for adrenal treatment. Primary hyperaldosteronism is known to be frequently characterized by multiple adrenal lesions. The indication of laparoscopic partial or total adrenalectomy in patients with aldosterone producing adenoma (APA) remains controversial. We performed the 2 procedures and compared the outcomes of these 2 operations retrospectively. MATERIALS AND METHODS A total of 92 patients with primary hyperaldosteronism were laparoscopically treated at our institution from 1995 to 2004. A total of 29 patients underwent partial adrenalectomy or enucleation, while unilateral total adrenalectomy was performed in 63. A single pathologist examined the number and histopathological characteristics of APAs. Postoperative median followup was 60.3 and 29.3 months, respectively. RESULTS Laparoscopic adrenalectomies were successfully performed in each group, although the partial type had fewer ports and shorter operative time. All 63 patients with total adrenalectomy showed recovery from hypertension, suppressed plasma renin activity and high plasma aldosterone. Two of 29 patients with partial adrenalectomy or enucleation still experienced hypertension with high plasma aldosterone. Of the 63 extirpated specimens 17 adrenals (27.0%) demonstrated multiple space occupying lesions along with the main APA. CONCLUSIONS Primary hyperaldosteronism is highly associated with multiple adrenal space occupying lesions. The risk-to-benefit ratio must be carefully weighed against the potential advantage of partial adrenalectomy. We chose total laparoscopic adrenalectomy in patients with unilateral APA and primary hyperaldosteronism.

Abstract
BACKGROUND This article reports an alternative laparoscopic access to left adrenal gland. METHODS From January 1994 to August 2004, 209 laparoscopic adrenalectomies were performed in our Department. Indications were Conn adenoma (55 cases), incidentaloma (64), Cushing adenoma (45), pheochromocytoma (32), adreno-genital syndrome (two), mielolipoma (two), and metastatic mass(nine). Of 209, in 12 cases the left adrenalectomy was performed through a submesocolic access (seven pheochromocytoma, two incidentaloma, two Cushing adenoma, one Conn adenoma,). The identification and closure of the adrenal vein with minimal gland manipulation resulted the main benefit of this approach. Moreover, the adrenalectomy was performed with minimal anatomical dissection. RESULTS No mortality or major complications occurred. During the operation, the blood pressure and cardiac rhythm were significantly more stable, in the group of patients who underwent a left adrenalectomy by the submesocolic approach compared to the anterior or flank lateral transperitoneal group. CONCLUSIONS Left adrenal lesions, as selected cases of pheochromocytoma, can be safely treated by laparoscopic submesocolic access.

Abstract
A patient presented with hypertension, hypokalemia, and a 1.2-cm left adrenal tumor. Conn's syndrome was diagnosed, for which laparoscopic adrenalectomy is now the therapy of choice. This case was complicated by an ipsilateral ectopic pelvic kidney. A laparoscopic left adrenalectomy was performed via a lateral transabdominal approach. Without the usual anatomic landmark of the ipsilateral kidney, the left adrenal gland was difficult to identify, so intraoperative ultrasound was used to locate the lesion. Postoperatively, the patient's blood pressure and potassium normalized. This is the first documented report of a laparoscopic adrenalectomy performed for adrenal adenoma with the anatomic disruption of an ipsilateral pelvic kidney.

Abstract
PURPOSE OF REVIEW The aim of this paper is to define the current role of laparoscopy in the management of surgical adrenal diseases evaluating the surgical aspects, the indications and contraindications of laparoscopic adrenalectomy, focusing also on the most innovative tendencies in the laparoscopic adrenal-preserving surgery. RECENT FINDINGS Recent publications have described some interesting new indications that need to be confirmed by long-term follow up. The present review mainly focuses on defining the state of the art of current adrenal laparoscopic surgery. SUMMARY Laparoscopic adrenalectomy is becoming the 'platinum standard' for the treatment of the adrenal surgical diseases and it should be considered the treatment of choice for benign adrenal diseases. In cases of malignancy and conservative surgery, adrenalectomy appears to be very promising, although a longer follow up and further studies are still needed to accurately assess the role played by these procedures. Finally, who should do laparoscopic adrenalectomy? Every patient who requires the ablation of the adrenal should receive laparoscopic opportunity. And the surgeons? Only those with advanced laparoscopic skills and a good knowledge of adrenal anatomy and pathophysiology will obtain the same excellent results currently reported in the literature.

Abstract
Adrenal incidentalomas are tumors that are serendipitously found by radiological examination. The incidence of adrenal incidentalomas in patients undergoing abdominal CT approaches 1 %. The evaluation of a patient with an adrenal incidentaloma requires, in addition to a clinical history and physical examination, a focused biochemical evaluation to investigate if there is excess secretion of catecholamines, glucocorticoids, or aldosterone. Some tumors have specific features on imaging that identify them as benign or malignant. The recommendations for management of adrenal incidentalomas include resection of all functioning tumors regardless of size, preferably by the laparoscopic approach. Large, non-functional tumors should also be removed. Biochemical and radiological surveillance is recommended for at least one year, if a tumor is left in place.

Abstract
The use of robotics in surgery is an emerging field. Robot-assisted laparoscopic adrenalectomy has been performed in small numbers worldwide. Advantages of robotic assistance over conventional laparoscopy are not acknowledged. Improvement in robotic technology, including addition of tactile feedback, miniaturization of end-effectors, reduced cost, and advances in remote surgery telecommunication technology are awaited.

Abstract
BACKGROUND Laparoscopic adrenalectomy (LA) has become the procedure of choice for small benign lesions. Compared with open adrenalectomy (OA), it appears to achieve superior results in terms of recovery, cosmesis and morbidity. METHODS A Medline literature search (PubMed database, 1990-2003) was undertaken to identify relevant English language papers. Studies comparing LA with OA were categorized according to their level of evidence. Variables of outcome were analysed systematically for various adrenal pathologies. RESULTS No prospective randomized studies comparing LA with OA were identified. According to 20 comparative case-control studies (level 3b) and many case-series reports (level 4), the results of LA were reproducible and it has consistently been associated with faster recovery and lower morbidity than OA. The clinical outcome in hormonally active lesions was similar. The lateral transabdominal approach was the laparoscopic technique of choice; it was practised by 78.6 per cent of surgeons. Lesion sizes of 10-12 cm were cited as the upper limit for LA in many large series. Experience of 70 malignancies demonstrated the feasibility of LA, with short-term oncological results comparable to those of conventional surgery. CONCLUSION Despite a lack of a high level of evidence in its favour, LA has practically replaced OA in the management of small and medium-size benign functioning and non-functioning adrenal lesions, as it has proved to be as effective as OA with less associated morbidity. Although limited experience with large and malignant tumours shows some promise, present data are insufficient for clear conclusions to be drawn.

Abstract
PURPOSE We used a lateral or posterior approach to perform retroperitoneoscopic adrenalectomy for adrenal tumors and compared the results to determine which approach is more advantageous. PATIENTS AND METHODS We removed 42 adrenal tumors from 42 patients by retroperitoneoscopic surgery. We used the posterior approach in 17 cases and the lateral approach in 25 cases. We compared the operating time, complications, and surgical advantages for the two approaches. RESULTS The mean operating time was significantly shorter with the lateral approach, 141 +/- 64 minutes v 225 +/- 88 minutes for the posterior approach (P = 0.0019), which we believe reflects the technical advantages of the lateral approach. Complications included one case of pneumothorax and an instance of pulmonary edema in a patient with chronic renal failure using the lateral approach and one occurrence each of pneumothorax and bleeding using the posterior approach. Retroperitoneoscopic adrenalectomy could not be performed in 1 of 25 cases (4.0%) using the lateral approach and in 3 of 17 cases (17.6%) using the posterior approach. CONCLUSION Our series suggests that the lateral approach is preferable to the posterior approach for retroperitoneoscopic adrenalectomy.

Abstract
We report our experience with bilateral adrenalectomy for treatment of Cushing's syndrome and we compare the outcome of laparoscopy with open surgery in terms of effectiveness and safety. A series of 23 patients underwent bilateral adrenalectomy for treatment of Cushing's syndrome [Cushing's disease in 16, ectopic ACTH syndrome in 2, and ACTH-independent macronodular adrenal hyperplasia (AIMAH) in 5 cases]. From 1993 to 1996, all patients were treated using an open approach (Group A), while from 1997 all patients were treated using a transperitoneal laparoscopic approach (Group B). The comparison between the 2 groups was performed considering patients characteristics, operative times, blood losses, intraoperative and post-operative complications, analgesic consumption, post-operative hospital stay and recovery. Open surgery was performed in 10 patients and laparoscopy in 13 patients. No significant difference was recorded between the two groups as to patients' characteristics and complications. Mean operative time was significantly increased in Group B, while post-operative hospital stay was significantly longer in Group A. Laparoscopic bilateral adrenalectomy can be safely and effectively employed to treat Cushing's syndrome. However, long operatives times may represent a limitation especially in high risk patients.

Abstract
OBJECTIVE To evaluate the feasibility of laparoscopic adrenalectomy for pheochromocytoma. MATERIAL Between January 1998 and March 2002, 12 patients aged from 19 to 76 (average age 54 years) underwent 13 adrenalectomies (7 right and 6 left, 1 bilateral) using laparoscopic surgery. A specific anti-hypertensive preparation was begun prior to the operation. Peaks of blood pressure were treated by bolus Nicardipine and sinus tachycardia by bolus Esmolol. Catecholamines were dosed at different times during the intervention. As far as surgery was concerned, the adrenalectomies were performed 11 times using the transperitoneal route and twice using the retroperitoneal route. The adrenal vein was found and ligatured before manipulation of the adrenal gland. RESULTS Average length of operation was 127 minutes (75 to 195). Average blood loss was 105 ml (0 to 1000). Catecholamines dosed throughout showed a variable increase in plasma rates during peritoneal insufflation and manipulation of the gland. They were responsible for 5 cases of hypertensive bouts and 2 cases of tachycardia which were treated with medication. No surgical conversions were necessary. Average length of hospital stay was 4.18 days (3 to 6); average size of adrenal tumours was 44 mm (30 to 72); average follow-up, 18.4 months. CONCLUSION This study showed the feasibility of adrenalectomy for pheochromocytoma using laparoscopic surgery, subject to specific medical preparation to reduce the consequences of peroperative bouts of hypertension and sinus tachycardia during peritoneal insufflation and manipulation of the adrenal gland despite initial ligature of the main adrenal vein.

Abstract
Adrenocortical carcinoma is a rare cancer that historically has been associated with poor outcome. Throughout the past decades, growing experience has allowed better understanding of the natural history and optimal management of this cancer. Advances in imaging and aggressive surgical therapy have raised the outlook for recently diagnosed patients. Further improvements in survival will require more effective systemic therapy.

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
BACKGROUND It is unclear whether resection of clinically isolated metastasis to the adrenal gland improves survival. Also, the role of laparoscopic adrenalectomy (LA) for metastasis is controversial. This study aimed to (1) identify patients who are most likely to have prolonged survival after resection of adrenal metastasis and (2) compare oncological outcomes of LA and open adrenalectomy (OA). METHODS A retrospective review of 41 patients, who underwent either OA or LA for metastasis to the adrenal gland during 1997-2002 at a single institution, was conducted. RESULTS There were 20 women and 21 men, with a median age of 59 years. The most common disease was non-small-cell lung carcinoma (n = 23), followed by renal cell carcinoma (n = 6). With a median follow-up of 16 months, the overall five-year actuarial survival was 29% (median, 28 months). Four patients were actually alive at four years after adrenalectomy. Disease-free interval (DFI) > 6 months was the only significant predictor of improved survival. LA was performed for 11 patients. There was no difference in the incidence of positive resection-margins or survival between patients with OA or LA. CONCLUSIONS Adrenalectomy for metastasis, with intent to prolong survival, should be offered to patients with favorable tumor biology, such as those with significant DFI. The oncological outcome from LA appears similar to that from OA.

Abstract
OBJECTIVE To determine the safety and results of laparoscopic resection of benign pheochromocytomas. PATIENTS AND METHODS We retrospectively reviewed the medical charts of all patients who underwent laparoscopic adrenalectomy for benign pheochromocytomas at all 3 Mayo Clinic sites between January 1, 1992, and December 31, 2001. Demographics, comorbidities, clinical presentation, imaging studies, biochemical findings, operative intervention, and outcome were examined. Long-term follow-up was obtained via chart review and/or by direct telephone contact with the patient or a relative. RESULTS Twenty-four women and 23 men with a mean age of 53.1 years (range, 16-81 years) underwent attempted laparoscopic resection of pheochromocytomas. In 5 patients, the procedure was converted to open laparotomy because of bleeding (2), inadequate exposure (2), and adhesions (1). The mean tumor size was 4.3 cm. The mean operative time (181.8 vs 1405 minutes; P = .03), mean hospital stay (6.00 vs 2.64 days; P < .001), and mean blood loss (340 mL vs 80 mL; P < .001) were greater in patients who underwent open laparotomy vs those who underwent laparoscopic resection. All specimens were classified as benign. The mean follow-up was 41 months (range, 10-89 months). No patients experienced a recurrence or developed metastatic disease. CONCLUSIONS In light of surgical and anesthesia expertise, laparoscopic resection of benign pheochromocytomas is safe and effective with resultant short hospital stays. A low threshold to convert to an open procedure reduces operative times and decreases potentially serious complications. Although there have been no recurrences to date, long-term follow-up is required for all patients, especially those with hereditary forms of pheochromocytomas.

Abstract
Use of three-dimensional (3D) volume-rendered helical computed tomography (CT) in surgical planning before laparoscopic adrenalectomy was evaluated in a retrospective study. In 35 consecutive patients before laparoscopic adrenalectomy, 3D volume-rendered CT scans were created from helical CT scans. Videotapes that showed anterior, lateral, posterior, and posterocephalic approaches were assessed retrospectively. The relationship (not contacting, abutting, displacing, or invading) of adrenal masses to adjacent organs (diaphragm, liver, spleen, kidneys, stomach, pancreas, and vessels) was recorded and compared with findings in surgery reports. When such findings were available, they corresponded to those in the videotape. Three-dimensional volume-rendered CT successfully displayed the relationship of adrenal masses to adjacent anatomic structures and organs before laparoscopic adrenalectomy.

Abstract
BACKGROUND Since the first laparoscopic adrenalectomy was performed in 1992, it has quickly gained acceptance as the standard of care for the treatment of benign adrenal neoplasms. We report a single surgeon's experience with 100 consecutive laparoscopic adrenalectomies. METHODS The records of all patients having adrenalectomy at the Johns Hopkins Hospital from 1993 until 2000 were reviewed. We examined the length of stay, time to diet resumption, perioperative morbidity, operative cost, and total cost of 100 consecutive laparoscopic adrenalectomies. These data are compared with those of 20 patients within our institution having open adrenalectomy and with 428 patients statewide having all forms of adrenalectomy during the same time period. RESULTS A total of 93 patients had unilateral laparoscopic adrenalectomy and 7 had bilateral procedures. The mean age was 49 years (11 to 70). Indications were aldosteronoma (n = 40), pheochromocytoma (n = 22), glucocorticoid-producing adenoma (n = 14), nonfunctioning adenoma (n = 12) Cushing's disease (n = 5), and others (n = 7). The median length of stay for this series was 1.0 day. Average length of stay and time to resumption of diet were 1.8 and 1.0 days, respectively. Patients having open procedures during this same time period had an average length of stay of 6.5 days. CONCLUSIONS Laparoscopic adrenalectomy provides clear advantages over open adrenalectomy. Patients having laparoscopic adrenalectomy have decreased length of stay, shorter time to resumption of diet, and lower total hospital charges when compared with those having open adrenalectomy.
