Abstract
The adrenal gland is a retroperitoneal organ with intimate relationships with neighboring organs but also with the large retroperitoneal vessels. Our aim was to study the vascular relationships of the adrenal gland with the large abdominal vessels. Our work is an anatomical dissection of 80 fresh cadaveric adrenals. The subjects didn't have a history of retroperitoneal surgery. Dissection conditions were similar to those in the living. All measurements were made in situ. On the right side, the average distance between the adrenal gland and the renal vein (DR) was 13 mm (0-20). In one case, the adrenal gland laid directly on the right renal vein (DR = 0). The average length L, over which the right adrenal gland entered behind the inferior vena cava (IVC), was 8 mm (0-12). In 4 cases, the right adrenal was lateral to the IVC and in 6 cases the length L exceeded 10 mm. On the left side, the mean distance DL, separating the adrenal gland from the left renal vein was 8 mm with extremes ranging from 0 mm to 18 mm. In eleven cases, the adrenal gland laid directly on the left renal vein. The right adrenal gland has a close relationship with the IVC and is often located behind it. This close relationship helps to explain the increased incidence of IVC lesions during surgery. The left adrenal gland has an intimate relationship with the left renal vein and often lies on top of it. This explains the risk of injury to the left renal pedicle during left adrenal surgery.

Abstract
The laparoscopic approach represents the standard of treatment for renal and adrenal diseases, and its use is increasing even outside referral centres. Although most procedures are routinely performed, intraoperative complications do not occur, and the rate and predictive factors of these complications have not been established. The aim of this study was to evaluate the incidence and type of intraoperative complications and to identify predictive factors in patients undergoing laparoscopic renal and adrenal surgery. This was a cohort, multicentre, international retrospective study. Patients who underwent laparoscopic renal and adrenal surgeries between April 2017 and March 2022 were included in the study. Bivariate analysis was performed using contingency tables and the χ2 test for independent samples to compare qualitative variables and the T test and Mood test for continuous variables. Multivariate analysis was performed using a logistic regression model to obtain adjusted odds ratios. A total of 2374 patients were included in the study. Intraoperative complications were reported for 8.09% of patients who underwent renal surgery, with the most common complications reported being hollow viscus and vascular complications, and for 6.75% of patients who underwent adrenal surgery, with the most common complication reported being parenchymatous viscous complications. Multivariate analysis revealed that both adrenal and renal surgery radiological preoperative factors, such as invasive features during adrenalectomy and the RENAL score during nephrectomy, are predictive factors of intraoperative complications. In contrast to existing data, surgeon experience was not associated with a reduction in the incidence of perioperative complications.

Abstract
To evaluate the feasibility and clinical significance of the left perinephric fat sac vein (PFSV) as an anatomical landmark in locating left adrenal gland (LAD) during retroperitoneal laparoscopic left adrenalectomy (RLLA). In this study, a total of 36 patients who underwent RLLA were enrolled from February 2019 and March 2021. By following a vein vessel on the internal surface of perinephric fat sac (PFS), known as PFSV, LAD was searched finally along the upper edge of this vein. The demographic and clinical characteristics of these patients were acquired, including tumor features and perioperative outcomes (operating time, estimated blood loss, complications). The operations were successfully completed in all the 36 patients without conversion to open surgery. In addition, the LAD was successfully found along the upper edge of PFSV in 34 patients. For all operations, the mean operative time was 75 min (range 60-95) and the estimated blood loss was 20 ml (range 10-50). The median oral intake was 20.7 h (range 6-39). The median hospital stay was 6.3 days (range 4-9), and the median follow-up was 12.3 months (range 9-17). Moreover, no intraoperative complications were observed and no residual tumors were detected after 9 to 15 months follow-up. It may be a safe and efficient procedure to use PFSV as a landmark for searching LAD during RLLA, especially for beginners. However, more studies with larger sample size are need to be conducted to further evaluate the outcomes of this method and the significance of PFSV in searching LAD during RLLA.

Abstract
"Pheochromocytomas are rare neuroendocrine tumors that frequently have genetic involvement and can present a particular risk in terms of the anesthetic-surgical procedure. Current worldwide medical recommendations state that laparoscopic adrenalectomy is the conventional treatment for pheochromocytoma, however, the ideal surgical strategy is still being developed as specialized surgeons gain experience with these rare tumors. The study's purpose was to thoroughly evaluate our film library and identify the best surgical steps that represent our standardized procedure. We developed a comprehensive set of surgical critical strategies for either a left or right adrenalectomy, providing helpful advice on patient positioning, port placement, the adrenal gland approach, as well as other surgical methods specifically designed for tumor mobilization and dissection. The current paper aims to synthesize our clinical experience in terms of preoperative preparation, patient positioning, intraoperative complications, causes of conversion, and specimen extraction. The main conclusions concern both the best surgical approach and the importance of surgical experience in the clinical management of these rare tumor types. "

Abstract
PURPOSE Oncology patients undergoing positron emission tomography/computed tomography (PET/CT) occasionally show discrete adrenal [18F]-fluorodeoxyglucose (FDG) uptake without an associated nodule on CT, leaving the clinician uncertain about the need to proceed with biopsy or surgical referral. This study aimed to identify the prevalence of this radiological finding and to evaluate the effectiveness of FDG uptake values in risk stratification for adrenal metastasis. METHODS From 2014 to 2015, oncology patients who underwent FDG-PET/CT and demonstrated elevated FDG uptake in the adrenal gland without discrete nodularity on cross-sectional imaging were included in a retrospective cohort analysis. Clinical records and FDG-PET/CT scans were reviewed for clinicopathological data, follow-up data, SUVmax (highest SUV of either adrenal gland), and SUVratio (SUVmax/background liver uptake). A receiver operating characteristic analysis was conducted to evaluate the associations between SUV values and the progression to adrenal metastasis. RESULTS Of 3040 oncology patients who underwent FDG-PET/CT scans, 92 (3.0%) showed elevated adrenal uptake without associated mass. From the final study cohort of 66 patients with comprehensive follow-up data, 5 patients (7.6%) developed evidence of adrenal metastasis. At SUVmax < 3.25 (AUC = 0.757) and SUVratio < 1.27 (AUC = 0.907), 34.8% and 60.6% of patients could be excluded with 100% negative predictive value, respectively. CONCLUSIONS Thresholds of SUVmax and SUVratio identified a significant proportion of patients who did not develop adrenal metastasis. In oncology patients who demonstrate increased adrenal FDG uptake without a discrete lesion on FDG-PET/CT, quantitative uptake values may be useful in selecting those not at risk of developing adrenal metastatic disease.

Abstract
BACKGROUND As the incidence of adrenalectomy increases steadily, so does the use of minimally invasive approaches like posterior retroperitoneoscopic adrenalectomy (PRA). To date, the largest studies of PRA have been from abroad, and we sought to provide a contemporary US update on the outcomes after PRA. METHODS A retrospective chart review was conducted on all PRAs performed at a single tertiary care institution between 2013 and 2020. Patient demographic characteristics, indication for operation, operative details, and postoperative course were abstracted. Outcomes of interest included 30-day mortality, conversion to open or transabdominal approach, postoperative complication, and 30-day readmission. RESULTS A total of 249 PRAs were performed between 2013 and 2020. The population was 54.2% women and mean (SD) age was 54.1 (14.1) years. Most lesions (60.6%) were left-sided, and the most common diagnosis was nonfunctioning adenoma (39.4%), followed by pheochromocytoma (21.3%) and aldosteronoma (16.6%). Mean (SD) tumor size was 3.2 cm (range 0.5 to 9.4 cm). Median operative length was 110 minutes (range 30 to 319 minutes). Overall, the complication rate was 6.4%. Nine patients (3.6%) had a minor postoperative complication (Clavien-Dindo I to III) and 5 patients (2.0%) had a major postoperative complication (Clavien-Dindo IV to V), including 1 mortality (0.4%). There were 2 conversions of approach (0.8%). The majority of patients (58.2%) were discharged on postoperative day 1, and 92.0% were discharged by postoperative day 3. The 30-day readmission rate was 1.6%. CONCLUSIONS Current practice demonstrates that PRA is an extremely safe approach, with a complication rate < 7% and mortality rate < 1%. In addition, the vast majority of patients are able to return home in an expedient manner.

Abstract
Introduction Lateral transabdominal adrenalectomy (LTA) is the most common minimally invasive technique used to treat patients with adrenal tumors. Aim To analyze intra-operative and post-operative complications and reasons for conversion to open surgery in patients who underwent LTA and had previous abdominal surgery. Material and methods Five hundred and nineteen patients underwent LTA in our center between 2005 and 2016. We identified a study group of 150 patients, with previous abdominal surgery. We analyzed the frequency of intra-operative and post-operative complications and the reasons for conversion from laparoscopic to open adrenalectomy. Results The patients’ mean age was 58; they underwent LTA due to hormonally active tumors (n = 79, 53%) and non-functioning adrenal tumors (n = 71, 47%). The size of adrenal lesions ranged from 20 mm to 90 mm. Seventy-eight (52%) adrenal lesions were found in the right adrenal gland, and 72 (48%) lesions in the left adrenal gland. The mean operating time was 130 min. The mean stay in hospital was five days. The intra-operative complications included blood pressure fluctuations (n = 32), abnormal vascular supply of the adrenal glands causing difficulties with dissections (n = 3), and respiratory problems (n = 1). Two (1.3%) patients had post-operative bleeding at the site of removed adrenal glands; 1 patient had an exacerbation of asthma postoperatively. Of the 150 patients analyzed, 3 (2%) required conversion to open adrenalectomy. The conversions were not caused by abdominal adhesions. Conclusions Lateral transabdominal adrenalectomy is feasible and safe in patients with previous abdominal surgery. In our study, conversion from laparoscopic to open adrenalectomy was not caused by abdominal adhesions.

Abstract
Over the last decade minimally invasive adrenalectomy has become the gold standard in adrenal surgery. Laparoscopic adrenalectomy with the patient in the lateral decubitus position and posterior retroperitoneoscopic adrenalectomy have gained worldwide acceptance. In this overview the complications of minimally invasive adrenalectomy are analyzed based on the published data. Die incidence of intraoperative and postoperative complications ranges from 0 % to 15 % for unilateral adrenalectomy and rises up to 23 % for bilateral surgery. No significant differences were found between laparoscopic and retroperitoneoscopic operations. Nevertheless, splenic injuries and intra-abdominal abscesses are reported only after laparoscopic procedures, while relaxation and/or hypoesthesia of the abdominal wall are typical for posterior retroperitoneoscopic surgery. Conversion to open surgery significantly influences the rate of perioperative and postoperative complications (odds ratio 6.2); therefore, high surgeon and center case volume could improve the results of adrenal surgery.

Abstract
This study emphasizes the importance of careful preoperative imaging and select port positions appropriate for the targeted organ in patients with situs inversus undergoing laparoscopic surgery. Background: Situs inversus is a relatively rare congenital disease. A patient with a right adrenal tumor complicated by total situs inversus was treated by laparoscopy. Case Discussion: The patient was a 45-y-old male with lower limb weakness. He had been diagnosed with situs inversus during a general health check-up as an infant. His blood pressure was 230/160 mm Hg, and the serum potassium level was 2.0 mEq/L. Abdominal ultrasonography and magnetic resonance imaging showed a mass of about 2cm in diameter in contact with the right adrenal gland. Total situs inversus was simultaneously confirmed. The plasma aldosterone concentration was elevated to 442pg/mL, and renin activity was suppressed, at 0.3ng/mL/hr. Discussion: These findings indicated a diagnosis of primary aldosteronism due to an adrenal tumor, and the right adrenal tumor was resected laparoscopically. The right adrenal gland was approached and resected from the lateral side of the spleen, which was located on the right side because of situs inversus. The resected specimen was 4.5cm×1.6cm, and no intraoperative complications occurred. The histopathological examination showed the tumor to be an aldosterone-producing adrenocortical adenoma.

Abstract
PURPOSE To describe the surgical technique, to analyze outcomes and to provide an overview of the current status of laparoendoscopic single site (LESS) adrenalectomy. METHODS A comprehensive PubMed search was performed for all relevant urological literature regarding LESS and adrenal surgery. In addition, experience gained at the authors' own institutions was considered. Clinical descriptive and comparative reports on LESS adrenal surgery procedures were analysed. RESULTS LESS adrenal surgery has been effectively performed for a number of indications. A wide variety of approaches (transperitoneal versus retroperitoneal, multichannel trocar versus multiple ports, trans- or extraumbilical) have been described. LESS adrenalectomy seems to be safe, taking more time than the standard laparoscopic counterpart but appears to offer the patient less postoperative discomfort. Technical difficulties of the procedure include the requirement of more time for adjustment of articulating instruments, longer 'one-handed' manipulation time, and a high peroperative tissue re-grasping rate. CONCLUSIONS The feasibility and safety of LESS adrenalectomy has been demonstrated. Only long-term follow-up outcomes will prove its benefits over conventional laparoscopy and define the role and the oncological safety of LESS adrenal surgery.

Abstract
OBJECTIVE To evaluate the safety and feasibility of laparoscopic adrenalectomy (LA) performed in several German centres with different laparoscopic experience, as LA has become the gold-standard approach for benign surgical adrenal disorders; however, for solitary metastasis or primary adrenal cancer its precise role is uncertain. PATIENTS AND METHODS The data of 363 patients who underwent a LA were prospectively collected in 23 centres. All centres were stratified into three groups according to their experience: group A (<10 LAs/year), group B (10-20 LAs/year) and group C (>20 LAs/year). In all, 15 centres used a transperitoneal approach, four a retroperitoneal approach and four both approaches. Demographic data, perioperative and postoperative variables, including operating time, surgical approach, tumour size, estimated blood loss, complications, hospital stay and histological tumour staging, were collected and analysed. RESULTS The transperitoneal approach was used in 281 cases (77.4%) and the retroperitoneal approach was used in 82 patients (22.6%). In all, 263 of 363 lesions (72.5%) were benign and 100 (27.5%) were malignant. The mean (sd) operating time was 127.22 (55.56) min and 130.16 (49.88) min after transperitoneal and retroperitoneal LA, respectively. The mean complication rates for transperitoneal and retroperitoneal LA were 5% and 10.9%, respectively. CONCLUSION LAs performed by urologists experienced in laparoscopy is safe for the removal of benign and malignant adrenal masses. LA for malignant adrenal tumours should be performed only in high-volume centres by a surgeon performing at least >10 LAs/year.

Abstract
AIM: To develop a pure transvaginal access to the retroperitoneum, that is simple, reproducible and uses endoscopic material available on the market.
METHODS: From February 2008 to April 2009, 31 pigs were operated on, with 17 as an acute experiment and 14 with a survival protocol. The animals were placed in a supine position and a 12-mm double-channel endoscope (Karl Storz™, Tuttlingen) was used for vision and dissection. During the same time period, the access experiment was reproduced on 3 human cadavers using material similar to that used in the animal model.
RESULTS: In the animal model, 37 interventions were done on the kidney, adrenal gland and pancreas. The mean time to fashion the access was 10 min (range 5 to 20 min). No intraoperative death was observed. Two major (5%) intraoperative complications occurred: one hemorrhage on the aorta and one tearing of the right renal vein. Peritoneal laceration was encountered in 5 cases without impairing the planned task. In the survival group, good clinical outcome was observed at a mean follow-up of 3 wk (range 2 to 6 wk). In the 3 cadavers, access was performed correctly. The mean time to fashion the access was 52 min (range 40 to 60 min). All the anatomical landmarks described in the pig model were clearly identified in the same sequence.
CONCLUSION: A retroperitoneal natural orifice translumenal surgical transvaginal approach is feasible in both animal and human models and allows performance of a large panel of interventions.

Dalvi AN, Thapar PM, Shah NS, Menon PS. Has experience changed the scenario in laparoscopic adrenalectomy? Indian J Surg 2009; 71:78-83. [PMID: 23133120 PMCID: PMC3452617 DOI: 10.1007/s12262-009-0021-8] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2008] [Accepted: 02/15/2009] [Indexed: 11/24/2022] Open
Abstract
BACKGROUND Laparoscopic adrenalectomy (LA) is a relatively uncommon operation performed by surgeons with a specific interest in endocrine surgery as well as advanced laparoscopic surgery. LA is technically difficult and it is recommended to tackle small glands first till adequate experience is reached [1]. A minimum of 30 cases are required to master the technique [2]. The present study reviews data of 60 laparoscopic adrenalectomies comparing the later results with the first 30 cases. MATERIAL AND METHODS Starting 2001, patients diagnosed to have adrenal disorders were subjected to laparoscopic approach in a graded manner. A database was maintained with respect to age, sex, duration of symptoms, co-morbid conditions, diagnosis, size of tumor, weight of tumor, blood loss, duration of surgery, conversion to open, in-hospital stay, referral pattern, morbidity (both early and late) and mortality. The database was divided into two groups. First 30 patients constituted Group A, Group B constituted the next 30 adrenalectomies and deviation in the two was noted. Statistical analysis was performed to determine the importance of deviation of factors. RESULTS Sixty adrenalectomies were performed in 49 patients (11 being bilateral) between February 2001 and July 2008. Age group varied from 12-54 years with mean of 30.73 years, Twenty four were males. Thirty-one right and 29 left LA were performed. The comparison of factors in relation to the two groups (Group A and B respectively) revealed an increase in number of adrenalectomies performed (0.4 v/s 0.76) in relation to timeline, increased incidence of pheochromocytoma (6 v/s 18) and incidentalomas (zero v/s 8), larger tumor size (4.17 cm v/s 6.6 cm), comparable blood loss (72 cc v/s 98.3 cc) and duration of surgery (122 min v/s 112 min), increased conversion to open surgery (1 v/s 6) leading to increased in-hospital stay (2.8 days v/s 3.37 days) but a comparable morbidity (2 v/s 1) and no mortality. CONCLUSION Though technically difficult, with increasing experience and focused approach, laparoscopic skills in adrenalectomy improves. The spectrum of indications broadens, thus making laparoscopic interventions for vascular and large adrenal glands safe and patient friendly.

Abstract
Surgery of the adrenal glands has various approaches and remains technically challenging. Many different techniques have been used to decrease morbidity. The most important one is probably laparoscopy which has already quite dramatically improved clinical outcome. The second one is the introduction of posterior endoscopic approach (retroperitoneoscopy), which entirely preserves peritoneal integrity. This concept seems to us to be a fundamental in surgery of the retroperitoneum. Recently, new developments have emerged in the field of abdominal surgery. The most radical concept, known as Natural Orifice Transluminal Endoscopic Surgery (NOTES), consists of the introduction of both endoscope and working instruments through natural orifices in order to eliminate skin incisions and their associated morbidities. Although transperitoneal adrenalectomy has previously been reported in a porcine model, here we report our initial experiences of extra-peritoneal transvaginal NOTES approach of the retroperitoneum, focused on the field of adrenal surgery in both porcine and cadaver models. Whether clinical applications will ultimately be derived of this concept is still not clear certainly it raises new possibilities for interesting developments.
