Surgery is the treatment of choice for adrenocortical carcinoma (stage I–III). In recent years, many authors demonstrated the safety and feasibility of minimally invasive approaches when applied to highly selected cases. The aim of the present study is to provide an overview about technical details and surgical and oncological outcomes of robotic approach compared to traditional open or laparoscopic surgery in patients with adrenocortical carcinoma. A literature search, according to the PRISMA guidelines, was performed via PubMed, Scopus, and Cochrane Library. The search thread was robotic adrenalectomy, minimally invasive surgery, and adrenocortical carcinoma. Only studies involving patients with adrenocortical carcinoma comparing robotic approach with laparoscopic and open adrenalectomy and reporting relevant clinical outcomes were included. Among all reports identified, only three studies matching the inclusion criteria were finally selected for the analysis. All of them were retrospective and demonstrated the superiority of robotic approach over laparoscopy for adrenocortical carcinoma as regards open conversion rate with no significant differences in terms of length of stay, readmissions, and 90-day mortality. A study reported significantly higher odds of positive margins for laparoscopic adrenalectomy that seems to be associated with significantly shorter overall survival. The most relevant reports strictly concerning the robotic approach to adrenocortical carcinoma revealed the safety and feasibility of robotic surgery with better outcomes in terms of open conversion rate and negative resection margins that are powerful predictors for overall survival. Multicenter case series analysis is still needed to confirm the real advantages of robotic approach in the treatment of adrenocortical carcinoma. [ABSTRACT FROM AUTHOR]

Abstract Robotic adrenalectomy (RA) has gained significant popularity in the management of adrenal gland diseases. We report our experience at a single tertiary institution and evaluate the safety and surgical outcomes of RA. The data of 122 consecutive patients who underwent RA from October 2009 to December 2022 at Korea University Anam Hospital (Seoul, Korea) were reviewed. There were no perioperative complications. Clinicopathological features and surgical outcomes were retrospectively analyzed through complete chart reviews. Noteworthy findings include the influence of sex, tumor size, and body mass index on operation time, with the female and small tumor groups exhibiting shorter operation times (P = 0.018 and P = 0.009, respectively). Pheochromocytoma was identified as a significant independent risk factor for a longer operation time in the multivariate analysis [odds ratio (OR), 3.709; 95% confidence interval (CI), 1.127–12.205; P = 0.031]. A temporal analysis revealed a decreasing trend in mean operation times across consecutive groups, reflecting a learning curve associated with RA adoption. RA is a safe and effective operative technique alternative to laparoscopic adrenalectomy that has favorable surgical outcomes and enhances the convenience of the operation.

Background: Robotic adrenalectomy has become a surgical treatment option for benign and selected malignant adrenal diseases. We aimed to evaluate the eligibility of two-port robotic posterior retroperitoneoscopic adrenalectomy (PRA) as an alternative to the conventional three-port technique by comparing their surgical outcomes. Materials and Methods: This retrospective cohort study compared the clinicopathological factors and surgical outcomes among 197 patients who underwent two-port or three-port robotic adrenalectomy between 2016 and 2020 in a single tertiary center. For further evaluation, propensity score matching was performed to reduce the selection bias in population characteristics. Results: Patients were categorized by the number of ports (two-port group, 87; and three-port group, 110). The two-port group compared with the three-port group was significantly older (P = .006) and had a smaller mean tumor size (P = .003) and shorter mean operation time (P = .001). Upon comparing clinicopathologic characteristics according to adrenal disorders, for pheochromocytoma, the three-port group had a larger tumor size and a longer operation time. For Cushing's syndrome, the operation time was short and numeric rating scale pain score was significantly low in the two-port group. After propensity score matching, the two-port group had a short operation time and a significantly low postoperative pain score (P < .05). Predictive factors associated with prolonged operation time included male gender, an increased number of ports, and large tumor size. Conclusions: The two-port technique resulted in a shorter operation time and lower pain score compared with the three-port technique. The two-port technique may be a safe alternative to the conventional three-port technique for robotic PRA. [ABSTRACT FROM AUTHOR]

Hypertensive crisis is rare in children. Among the rarest causes leading to this acute crisis, is bilateral adrenal tumour as a part of a syndrome, Von Hippel Lindau syndrome. The treatment is based on the excision of the adrenal tumour followed by long term surviellence. The authors present a case where conventional imaging with ultrasound and contrast enhanced CT scan demonstrated a right side adrenal tumour with raised catecholamines.The small left side tumour got missed on conventional imaging and got picked up on DOTA scan. The persistence of hypertension in post operative period can be related to such hidden functioning tumours. In view of the size of tumour & raised dopamine associated with high incidence of malignancy, robotic surgery was used for bilateral adrenal tumour excision which confirmed the diagnosis of Pheochromocytoma (PCC).

Background: Laparoscopic adrenalectomy is currently considered the gold standard method for adrenal surgery. Open surgery is the most frequent technique preferred amongst surgeons who are faced with tumours of larger sizes or challenging lesions. Despite the increasing interest in laparoscopy, most centres still utilise open surgery for challenging adrenal cases. Patients and Methods: We retrospectively evaluated our successive 30 robotic adrenalectomies performed in the past 10 years and assigned the patients into 'difficult' and 'easy' groups. Patients with malignant tumours or tumour size of over 8 cm were assigned to the 'difficult group' and others to the 'easy group'. Groups were evaluated according to the demographic features of the patients, side of the operation, the body mass index (BMI) and laparotomy history. The duration of anaesthesia, amount of bleeding during surgery and the hospitalisation periods were also evaluated. Results: There is no statistically significant difference between the two groups considering age, gender, BMI value, operation side, presence or absence of a laparotomy history, the amount of bleeding during the operation and hospitalisation duration (P > 0.05). The anaesthesia duration was found to be higher in the 'difficult' patient group (P < 0.05). Conclusion: Our results present robust evidence to support the idea that robotic adrenalectomy is not only a doable but also a safe option for malignant and large adrenal masses.

Background: Over the last 20 years, the prevalence of severe obesity (body mass index ≥ 35 kg/m2) has almost doubled. This condition increases the challenge of laparoscopic adrenalectomy (LA) by creating problems with instrument reach, adequate exposure, and visualization. The aim was to compare perioperative outcomes of laparoscopic versus robotic adrenalectomy (RA) in severely obese patients. Methods: This was an institutional review board-approved retrospective study. Prospectively collected clinical parameters of patients who underwent LA versus RA between 2000 and 2021 at a single center were compared using Mann–Whitney U, ANOVA, Chi-square, and multivariate regression analysis. Continuous data are expressed as median (interquartile range). Results: For lateral transabdominal (LT) adrenalectomies, skin-to-skin operative time (OT) [164.5 (71.0) vs 198.8 (117.0) minutes, p = 0.006] and estimated blood loss [26.2 (15.0) vs 72.6 (50.0) ml, p = 0.010] were less in RA versus LA group, respectively. Positive margin rate, hospital stay and 90-day morbidity were similar between the groups (p = NS). For posterior retroperitoneal (PR) approach, operative time and perioperative outcomes were similar between LA and RA groups. Multivariate analysis demonstrated robotic versus laparoscopic technique (p = 0.006) to be an independent predictor of a shorter OT. Conclusion: There was a benefit of robotic over the laparoscopic LT adrenalectomy regarding OT and estimated blood loss. Although limited by the small sample size, there was no difference regarding perioperative outcomes between RA and LA performed through a PR approach. [ABSTRACT FROM AUTHOR]

Purpose: Adrenocortical carcinoma (A.C.C.) is a rare tumour, often discovered at an advanced stage and associated with a poor prognosis. Surgery is the treatment of choice. We aimed to review the different surgical approaches trying to compare their outcome. Methods: This comprehensive review has been carried out according to the PRISMA statement. The literature search was performed in PubMed, Scopus, the Cochrane Library and Google Scholar. Results: Among all studies identified, 18 were selected for the review. A total of 14,600 patients were included in the studies, of whom 4421 were treated by mini-invasive surgery (M.I.S.). Ten studies reported 531 conversions from M.I.S. to an open approach (OA) (12%). Differences were reported for operative times as well as for postoperative complications more often in favour of OA, whereas differences for hospitalization time in favour of M.I.S. Some studies showed an R0 resection rate from 77 to 89% for A.C.C. treated by OA and 67 to 85% for tumours treated by M.I.S. The overall recurrence rate ranged from 24 to 29% for A.C.C. treated by OA and from 26 to 36% for tumours treated by M.I.S. Conclusions: OA should still be considered the standard surgical management of A.C.C. Laparoscopic adrenalectomy has shown shorter hospital stays and faster recovery compared to open surgery. However, the laparoscopic approach resulted in the worst recurrence rate, time to recurrence and cancer-specific mortality in stages I–III ACC. The robotic approach had similar complications rate and hospital stays, but there are still scarce results about oncologic follow-up. [ABSTRACT FROM AUTHOR]

Background and Objectives: Laparoscopic adrenalectomy (LA) is the standard surgical approach for adrenalectomy. At present, robotic adrenalectomy (RA) has been introduced at various hospitals. This study evaluated our initial experience with robotic adrenalectomy compared with conventional laparoscopic adrenalectomy. Materials and Methods: From October 2018 to March 2022, 56 adrenalectomies were performed by a single endocrine surgeon. Thirty-two patients underwent LA (LA group), and twenty-four patients underwent RA (RA group). Results: Patients in the RA group were significantly younger than those in the LA group (48.6 ± 9.7 years vs. 55.1 ± 11.4 years, p = 0.013). The RA group had a shorter operation time than the LA group (76.1 ± 28.2 min vs. 118.0 ± 54.3 min, p < 0.001). The length of hospital stay and postoperative pain level between the two groups were similar. There were no complications in the RA group. There was no significant difference in the pathologic diagnosis between the two groups. The cost of surgery was significantly higher in the RA group than in the LA group (5288.5 US dollars vs. 441.5 ± 136.8 US dollars, p < 0.001). Conclusions: In our initial experience, RA showed a shorter operation time than LA and no complications. RA could be a viable alternative surgical option for adrenalectomy, notwithstanding its higher cost. [ABSTRACT FROM AUTHOR]

Background: Post-operative pain relief after abdominal operations is critical for patient satisfaction and rapid recovery. Narcotics have been a traditional part of postoperative analgesia, with transversus abdominis plane (TAP) block introduced recently. The aim of this study is to assess the efficacy of laparoscopic TAP block on postoperative pain control in patients undergoing minimally invasive adrenalectomy.Methods: This was an institutional review board-approved retrospective study. Parameters related to postoperative pain control were compared between patients who underwent robotic transabdominal lateral adrenalectomy with (after December 2018) or without laparoscopic TAP block (control group) (before December 2018) by one surgeon. Statistics were performed using Mann Whitney U and Chi-square tests.Results: There were 86 patients in the TAP and 83 patients in the control group. Groups were similar regarding demographic and clinical parameters. Despite the availability of intravenous acetaminophen to a higher percentage of patients in the control (31.3%) versus the TAP group (8.1%), 0-24 h lowest postoperative pain scores were significantly lower in the TAP group (P < 0.0001). In TAP versus control group, percentage of patients requiring narcotics and amount of narcotics used was lower (P = 0.04 vs P = 0.0004, respectively). Mainly due to less pain-related over-stay, percentage of patients requiring more than a day of hospital stay was less in the TAP (12%) versus control group (18%) (P = 0.01).Conclusion: To our knowledge, the utility of TAP block in patients undergoing minimally invasive adrenalectomy has not been reported in the past. This study shows that there may be benefits of laparoscopic TAP block in reducing post-operative narcotic usage while improving pain control in these patients. [ABSTRACT FROM AUTHOR]

Pheochromocytoma and paraganglioma are often associated with hereditary syndromes, particularly those involving genes such as RET , which is linked to multiple endocrine neoplasia type 2A. Genetic testing plays a crucial role in diagnosing these conditions, guiding treatment strategies, and providing early intervention options for the affected families. A 57-year-old man presenting with back pain was found to have a left adrenal tumor and a retroperitoneal tumor near the left renal hilum. Hormonal studies and imaging confirmed the diagnosis of pheochromocytoma and paraganglioma. The patient underwent robot-assisted laparoscopic surgery to remove the tumors. Postoperative multigene panel testing identified a mutation in RET  c.1901G > T (p.Cys634Phe) leading to the diagnosis of multiple endocrine neoplasia type 2A. Despite this genetic finding, no other endocrine tumors, such as medullary thyroid cancer or hyperparathyroidism, were detected at the time of diagnosis. The patient remains under close surveillance for the potential development of associated conditions. This case highlights the importance of comprehensive genetic testing in patients with pheochromocytoma and paraganglioma, particularly when hereditary syndromes are suspected. Genetic insights ensure precise management, allowing for tailored treatment and improved outcomes in patients with hereditary pheochromocytoma and paraganglioma., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

BackgroundDue to the technical advantages and the convenience it provides to surgeons, “robotic adrenalectomy” is a widely used procedure for adrenal surgeries. In this study, we aim to evaluate our robotic adrenalectomy experience and delineate the factors that have a substantial impact on surgical outcomes.MethodsSuccessive 0 transperitoneal robotic operations using the daVinci SI® platform were grouped according to the surgery side, malignant or benign pathologies, for adenoma or non-adenoma lesions, tumor size of less than 4 cm or above, body mass index below or above 30 kg/m2, and with or without laparotomy history. Groups were compared in terms of duration of the operations, amount of bleeding, and the duration of hospitalization.ResultsMorbidity developed in 5 patients (16.6%), and no mortality was observed. We had only one conversion to perform open surgery (3.3%). Operations performed for adenoma significantly last longer when compared with the non-adenoma group (p 4 cm) than in the smaller size group (p

Background: Recent studies have reported the feasibility of indocyanine green fluorescence imaging of adrenal tumors to guide dissection. Although the adrenal has been reported to concentrate the dye more than surrounding tissues, the amount of tissue distinction and how this compares with conventional vision has not been quantified before. The aim of this study is to quantify this distinction using color analysis. Methods: This was an institutional review board-approved retrospective study. By excluding adrenal cortical carcinoma, metastasis and pheochromocytoma, video recordings of 50 patients who underwent robotic transabdominal lateral adrenalectomy with indocyanine green (ICG) imaging for adrenocortical tumors between August 2015 and May 2018 were reviewed. Using a color analysis software, the pixel intensity of adrenal tumors versus adjacent retroperitoneal tissues was calculated for conventional red, green and blue, as well as indocyanine green (ICG) scales. Statistical analysis was performed using ANOVA. Results: A total of 50 patients underwent unilateral robotic transabdominal lateral adrenalectomy. All procedures were completed robotically without a conversion to laparoscopy or open. Morbidity was 4%. Measured pixel intensity of adrenal tumors was higher than adjacent retroperitoneal tissues for all conventional color and ICG modes (p < 0.0001), with the gradient being more pronounced for ICG green versus conventional red, green and blue modes. Conclusions: To our knowledge this is the first study attempting to encode tissue planes in robotic adrenalectomy. The results show that the visual contrast distinction observed between adrenal and adjacent retroperitoneal tissues can be quantified using pixel intensity. ICG enabled the distinction of tissue planes with a wider gradient compared to conventional RGB view, quantifying its subjective benefits reported in prior studies. [ABSTRACT FROM AUTHOR]

Introduction: The application of robotic adrenalectomy (RA) has been increasing. However, there is still controversy about whether RA is more feasible than laparoscopic adrenalectomy (LA) for pheochromocytoma (PHEO). Aim: To evaluate the efficacy and safety of RA vs. LA for PHEO. Material and methods: A literature search of the PubMed, Ovid, and Scopus databases was performed to identify eligible studies up to April 2021. All studies comparing RA versus LA for PHEO were included. Data were analysed using the Cochrane Collaboration's Review Manager (RevMan) 5.4 software. Results: Overall, 4 studies including 386 patients (RA 155; LA 231) were included. RA might have larger tumour size (WMD = 0.72 cm, 95% CI: 0.31 to 1.13; p < 0.001). There were no statistically significant differences in operative time (WMD = -12.49 min, 95% CI: -29.50 to 4.52; p = 0.15), estimated blood loss (EBL) (WMD = -28.48 ml, 95% CI: -58.92, 1.95; p = 0.07), transfusion rate (OR = 0.70, 95% CI: 0.07 to 7.07; p = 0.77), or conversion rate (OR = 0.44, 95% CI: 0.07 to 2.88; p = 0.39). There were no significant differences between the 2 groups in terms of postoperative complications (OR = 1.06, 95% CI: 0.62 to 1.82; p = 0.84) and Clavien Dindo score = 3 complications (OR = 1.15, 95% CI: 0.39 to 3.41; p = 0.80). Patients from the RA group could benefit from shorter length of hospital stay (WMD = -0.51 days, 95% CI -0.91 to -0.12; p = 0.01). Conclusions: RA is a feasible, safe, and comparable treatment option for PHEO. [ABSTRACT FROM AUTHOR]

Background and Objective: Robotic adrenalectomy (RA) has attracted interest as an alternative to laparoscopic adrenalectomy (LA) for patients with pheochromocytoma, although its beneficial effects are uncertain. Our aim was to compare RA and LA outcomes for these patients., Methods: Data for patients who underwent RA or LA for pheochromocytoma in 46 international centers between 2012 and 2022 were reviewed. We analyzed baseline characteristics and postoperative complications at discharge, 90 d, and 1 yr. We conducted propensity score matching (PSM; 1:1 ratio) and multivariable analyses to evaluate outcomes and risk factors for the occurrence of complications and higher Comprehensive Complication Index (CCI)., Key Findings and Limitations: Of 1755 patients, 1613 (91.9%) underwent LA and 142 (8.1%) underwent RA. Estimated blood loss, conversion rate, complication rate, and CCI at discharge, 90 d, and 1 yr were similar between the groups. However, RA was associated with a longer operative time in comparison to LA (100 vs 123 min; p < 0.001), but not after PSM (p = 0.120). Multivariable analysis revealed that Charlson comorbidity index (odds ratio [OR] 1.17, 95% confidence interval [CI] 1.07-1.29; p = 0.001), and tumor size per 1-cm increment (OR 1.13, 95% CI 1.07-1.21; p < 0.001) were independently associated with the incidence of complications, but there was no significant difference in complication rates between the LA and RA groups (OR 1.09, 95% CI 0.63-1.87; p = 0.767). After PSM, RA was associated with a lower rate of severe (grade ≥3a) complications in comparison to LA (p = 0.023)., Conclusions and Clinical Implications: RA is a safe alternative to LA and yields similar outcomes for patients with pheochromocytoma. RA may be associated with a lower likelihood of severe complications. Further studies are warranted to determine the role of robotic surgery in pheochromocytoma., Patient Summary: Pheochromocytoma is a rare tumor in the adrenal gland and the gold-standard treatment is surgical removal. We assessed patient outcomes after robot-assisted surgery compared with laparoscopic surgery and found that outcomes are similar, but the rate of severe complications may be lower if a surgical robot is used., (Copyright © 2024 European Association of Urology.

Background: Robotic adrenalectomy offers several clinical benefits if compared with laparoscopic adrenalectomy; however, its superiority is still under debate. The aim of this study was the investigation of differences between the two techniques, and a comparison when approaching right or left side adrenal lesions was further conducted. Materials and Methods: All patients undergoing laparoscopic and robotic unilateral adrenalectomy at our institution from January 2006 to December 2019 were collected and retrospectively analyzed. Statistical analysis was conducted; differences between the two cohorts were reported. Results: A total of 160 cases were included (84 patients in laparoscopic adrenalectomy-group [LA-g] 76 cases in robotic adrenalectomy-group [RA-g]). The groups were homogeneous for demographic data. No intraoperative complications were reported; mean amount of intraoperative blood loss was comparable. No cases of conversion to open surgery were required. RA-g presented a longer operative time than LA-g for right adrenalectomy (P = .05), no differences were noted for left side (P = .187). Overall morbidity was 21% for LA-g and 10.5% for RA-g (P = .087), with an inferior rate of surgical complications for RA-g (P = .024), and for robotic left adrenalectomy than robotic right procedure (P = .03). Length of hospital stay was shorter for RA-g (P = .005). Conclusions: Robotic adrenalectomy presents similar outcomes as laparoscopic approach with some benefits for selected cases. Left adrenal lesions seem to receive greater advantages from robotic technique. Large randomized controlled trials are required to determine the role of robotic adrenal surgery and if the indication can be standardized based on the laterality of adrenal procedure.

Purpose: The aim of the present study is to investigate the impact of the near-infrared (NIRF) technology with indocyanine green (ICG) in robotic urologic surgery by performing a systematic literature review and to provide evidence-based expert recommendations on best practices in this field. Methods: All English language publications on NIRF/ICG-guided robotic urologic procedures were evaluated. We followed the PRISMA (Preferred Reporting Items for Systematic Review and Meta-Analyses) statement to evaluate PubMed®, Scopus® and Web of Science™ databases (up to April 2019). Experts in the field provided detailed pictures and intraoperative video-clips of different NIRF/ICG-guided robotic surgeries with recommendations for each procedure. A unique QRcode was generated and linked to each underlying video-clip. This new exclusive feature makes the present the first "dynamic paper" that merges text and figure description with their own video providing readers an innovative, immersive, high-quality and user-friendly experience. Results: Our electronic search identified a total of 576 papers. Of these, 36 studies included in the present systematic review reporting the use of NIRF/ICG in robotic partial nephrectomy (n = 13), robotic radical prostatectomy and lymphadenectomy (n = 7), robotic ureteral re-implantation and reconstruction (n = 5), robotic adrenalectomy (n = 4), robotic radical cystectomy (n = 3), penectomy and robotic inguinal lymphadenectomy (n = 2), robotic simple prostatectomy (n = 1), robotic kidney transplantation (n = 1) and robotic sacrocolpopexy (n = 1). Conclusion: NIRF/ICG technology has now emerged as a safe, feasible and useful tool that may facilitate urologic robotic surgery. It has been shown to improve the identification of key anatomical landmarks and pathological structures for oncological and non-oncological procedures. Level of evidence is predominantly low. Larger series with longer follow-up are needed, especially in assessing the quality of the nodal dissection and the feasibility of the identification of sentinel nodes and the impact of these novel technologies on long-term oncological and functional outcomes.

Introduction: Adrenocortical carcinoma (ACC) is a rare tumor, often discovered at an advanced stage and associated with poor prognosis. Treatment is guided by staging according to the European Network for the Study of Adrenal Tumors (ENSAT) classification. Surgery is the treatment of choice for ACC. The aim of this review is to provide a complete overview on surgical approaches and management of adrenocortical carcinoma. Methods: This comprehensive review has been carried out according to the PRISMA statement. The literature sources were the databases PubMed, Scopus and Cochrane Library. The search thread was: ((surgery) OR (adrenalectomy)) AND (adrenocortical carcinoma). Results: Among all studies identified, 17 were selected for the review. All of them were retrospective. A total of 2498 patients were included in the studies, of whom 734 were treated by mini-invasive approaches and 1764 patients were treated by open surgery. Conclusions: Surgery is the treatment of choice for ACC. Open adrenalectomy (OA) is defined as the gold standard. In recent years laparoscopic adrenalectomy (LA) has gained more popularity. No significant differences were reported for overall recurrence rate, time to recurrence, and cancer-specific mortality between LA and OA, in particular for Stage I-II. Robotic adrenalectomy (RA) has several advantages compared to LA, but there is still a lack of specific documentation on RA use in ACC.

Introduction Advancements in radiological imaging technology have increased the discovery of adrenal incidentalomas. Large adrenal tumors (LATs) are not common, and the likelihood of malignancy increases with tumor size. LATs were defined as tumors larger than four centimeters (cm) with various pathologic diagnoses. Traditionally, open adrenalectomy was considered the gold standard for LATs, but with recent advancements in minimally invasive surgery (MIS), optimum perioperative and long-term outcomes are achievable by the MIS approach.   The findings presented in this paper show that even large adrenal masses measuring up to 21 centimeters can be safely removed using a minimally invasive approach. Methodology After Institutional Review Board (IRB) approval, we reviewed medical records of adult patients who had adrenalectomies at two Saudi Arabian centers from January 2013 to February 2023. Inclusion criteria were laparoscopic or robotic adrenalectomy and adrenal lesions ≥5cm. Pediatric patients and those with open adrenalectomies were excluded. Pre-surgery, patients had imaging studies to assess mass characteristics. Pheochromocytoma patients received a 2-week adrenergic blocker treatment. Perioperative data including demographics, comorbidities, mass characteristics, surgery details, and follow-up were analyzed using SPSS-23. Patients provided informed consent and had follow-up appointments and imaging. Results Our experience involved 35 patients, 29 of whom received laparoscopic treatment and six of whom underwent robotic surgery. Of the 35 patients, more than half were females (57.1%), with a mean age of 41.7±14.9 years, the youngest and oldest participants being 16 and 73 years of age, respectively. The mean body mass index (BMI) of the participants was in the overweight range (26±6.0 kg/m 2 ). The most common mode of presentation was incidental (42.9%), followed by hypertension (17.1%). Most patients had right-sided adrenal gland involvement (48.6%), with only four patients showing bilateral involvement. Most of the patients were classified as American Society of Anesthesiology score (ASA) 2 (40.0%) or ASA 3 (40.0%). Most of the patients were diagnosed with myelolipoma or adenoma (22.9% each) followed by pheochromocytoma (17.1%). The average estimated blood loss (EBL) was 189.3±354.6 ml for patients who underwent laparoscopic surgery and 80.0 ±34.6 ml for patients who underwent robotic surgery. The average operative room time (ORT) was 220.1±98.7 minutes (min) for laparoscopic surgery and 188.3±10.3 min for robotic surgery. One patient had to be converted from laparoscopic to open surgery due to aortic injury. The average length of stay (LOS) was 9.5±6.7 days for laparoscopic treatment and 5.5±1.9 days for robotic surgery. The mean tumor size in the greatest dimension was 8.0±4.4 cm. Only one patient who underwent unilateral laparoscopy experienced perioperative complications and converted to open surgery; nine patients who underwent unilateral laparoscopy required blood transfusion, and none of the patients who underwent robotic surgery required transfusion. None of the 35 patients experienced a recurrence of their adrenal disease during the mean follow-up period which lasted around 58 months. Conclusion MIS in Saudi Arabia is growing and is a safe method for LATs, with satisfactory surgical results compared to the traditional open surgery approach.

Background and Objectives: Despite an increased adaptation of robotic adrenalectomy, its advantages over laparoscopic adrenalectomy (LA) have not been defined. The aim of the study was to compare perioperative outcomes of robotic versus laparoscopic lateral transabdominal adrenalectomy using a large single-center experience., Methods: This was a retrospective single center study. Within 22 years, patients who underwent laparoscopic and robotic transabdominal lateral adrenalectomy were identified from a prospective institutional review board-approved database. Clinical and perioperative outcomes were compared using Mann-Whitney U and χ 2  tests., Results: There were 190 patients who underwent laparoscopic and 281 patients who underwent robotic transabdominal lateral adrenalectomy. The groups were comparable except for a higher percentage of female patients in the robotic group. For robotic versus LA, operative time and hospital stay were shorter, in addition to less blood loss, conversion to open and margin positivity, for pheochromocytoma and malignant tumors. Morbidity rates were similar between the two groups., Conclusions: Despite the limitations of a retrospective design, this large study demonstrates significant advantages of robotic versus laparoscopic transabdominal lateral adrenalectomy in terms of perioperative outcomes and margin clearance., (© 2023 Wiley Periodicals LLC.)

The article focuses on a rare case of rectal granular cell carcinoma that required abdominoperineal resection due to tumor invasion of the anal sphincters. Topics include the rarity of colorectal granular cell tumors requiring extensive surgical resection, the need for further research on malignant granular cell tumors, and the importance of surveillance for local recurrence and metastasis.

Adrenal myelolipoma is a rare mesenchymal tumour with benign biological behaviour that is mainly composed of mature adipose and myeloid tissue. Both sexes are equally affected, most commonly between the fifth and seventh decades of life. The diagnosis of adrenal myelolipoma is mostly incidental. Although it may occasionally be associated with necrosis, rupture and haemorrhage, causing abdominal pain, this tumour is usually asymptomatic. Consequently, management is conservative, while surgical treatment is reserved for symptomatic cases, or for masses growing quickly or to a size >6 cm. Giant myelolipomas (sized >10 cm) are rare. Open radical adrenalectomy is the standard treatment for giant myelolipomas, while the minimally invasive approach has been used in only few cases. We herein report the case of a patient with a giant adrenal myelolipoma who underwent robotic partial adrenalectomy. To the best of our knowledge, this is the largest giant adrenal myelolipoma treated with robotic surgery reported in the literature to date. A 55-year-old male patient underwent an abdominal computed tomography scan during follow-up after radical prostatectomy for prostate cancer Gleason Score 6 (ISUP 1) due to biochemical recurrence. The examination revealed a right hypodense adrenal mass, sized 16×13 cm. Abdominal magnetic resonance imaging confirmed the presence of characteristics suggestive of a myelolipoma. The patient did not report any symptoms. Due to the benign characteristics of the mass, robotic partial adrenalectomy and enucleation of the mass were performed. The operative time and estimated blood loss were 205 min and 100 ml, respectively. No intra- or postoperative complications occurred. The patient was mobilized on the first postoperative day and the time to flatus was 36 h; the length of hospitalization was 4 days. Histological examination confirmed the diagnosis of adrenal myelolipoma, sized 18×11.5×6 cm. No tumour recurrence occurred over a follow-up period of 12 months. In conclusion, robotic surgery allows performing partial adrenalectomy with a lower risk of bleeding and with preservation of healthy adrenal tissue, which is of paramount importance for the patient as it reduces recovery time and the need for medical substitution therapy.

Background: Over the last few decades, robotic surgery with the da Vinci system has become increasingly prevalent. Endocrine surgeons are witnessing a rapid growth in enthusiasm for robotic approaches for treating thyroid, parathyroid, and adrenal disease. For carefully selected patients, the robotic system may be the preferred technique, although its use remains controversial and indications are in evolution. The goal of this article is to review current robotic procedures for thyroidectomy, parathyroidectomy, and adrenalectomy, and scrutinize the existing literature for application of these approaches.Methods: We systematically searched and reviewed relevant articles on PubMed and MEDLINE databases for robotic or robot-assisted thyroidectomy, parathyroidectomy, or adrenalectomy.Results: The safety and feasibility for robotic thyroidectomy, parathyroidectomy, and adrenalectomy have been repeatedly demonstrated. Although robotic thyroid and parathyroid surgery offers better cosmetic results compared to the conventional open operation, remote-access techniques introduce new risks. Similar outcomes have been reported for laparoscopic and robotic adrenalectomy, but robot-assisted techniques may extend the capabilities of minimally invasive surgery, particularly performing subtotal adrenalectomy.Conclusions: While robotic procedures offer better ergonomics for the endocrine surgeon and improved cosmesis for the patient, the major drawback to the robot system almost universally is the higher cost. With new robotically assisted surgical devices on the way that could drive down costs and speed up innovation, the indications for robotic endocrine surgery may greatly expand.

Introduction: Laparoscopic adrenalectomy (LA) is accepted as the gold standard treatment for most adrenal pathologies. Open surgery is still considered the standard of care for large tumors and malignancies. In the past decade, robotic adrenalectomy (RA) has become an alternative to the laparoscopic and open approaches. The aim of this study was to analyze perioperative and postoperative outcomes in a series of consecutive nonselected patients undergoing a RA, to determine whether factors that negatively affect outcomes in LA (body mass index [BMI], size, and side of the tumor) have the same impact in RA.Materials and Methods: This is a single-center single-surgeon retrospective study with 43 patients who underwent a RA. Patients were divided into different groups according to tumor size (cutoff values of 5 or 8 cm), tumor side (left/right), and BMI (cutoff value of kg/m2). Perioperative and postoperative outcomes included operative time, length of hospital stay, blood loss, readmissions, complications, and conversions to open.Results: There were no significant differences between the groups with tumors <5 cm versus ≥5 cm regarding gender, age, race, BMI, American Society of Anesthesiologists (ASA) score, history of previous abdominal surgery, tumor side, and histopathological diagnosis (all P values ≥.06). There were no significant differences in any of the outcomes analyzed with respect to the tumor size (all P values ≥.14) except for a higher occurrence of complications in patients with tumors ≥8 cm versus <8 cm (P = .03). There were no significant differences in any outcomes related to side (left versus right) of the tumor nor BMI (<30 versus ≥30 kg/m2). The overall readmission and conversion rates were both 2.3% and no mortalities were registered.Conclusion: Patient's BMI, tumor side, and size did not demonstrate a negative impact on perioperative and postoperative outcomes of RA. This approach could potentially expand the indications of minimally invasive surgery. [ABSTRACT FROM AUTHOR]

Objective: To report the outcomes of transperitoneal robotic adrenalectomy (RA) procedures in five initial cases performed at two institutions. Methods: Between March 2012 and November 2014, five patients underwent RA. A transperitoneal approach was taken by using the da Vinci-S four-arm surgical robot. Outcomes were assessed retrospectively. Results: Mean patient age was 42.6±5.1 (range: 34-47) years. Mean body mass index was 30.5±4.5 (range: 23.2-35.2) kg/m². Median tumour size detected on radiological imaging was 3.1±1.7 (range: 1.2-6.0) cm. Mean operation time was 129.0±12.4 (range: 120-150) minutes and median estimated blood loss was 100.0±119.3 (range: 50-350) ml. No intraoperative or perioperative complications occurred according to the modified Clavien complication scale. Median duration of hospital stay was 2.0±1.7 (range: 2-6) days. The fourth robotic arm was used in two patients. Histopathology results demonstrated: metastasis of renal cell carcinoma occurred in 1 case, adrenal cortical adenoma in 2 cases, pheochromocytoma in 1 case, and hyperplasia in 1 case. After a median follow-up of 17.0±15.0 (range: 3-40) months, no local recurrence was detected. Conclusion: RA is a safe minimally invasive surgical approach that has excellent surgical and oncological outcomes in the treatment of adrenal masses

Introduction: Laparoscopic adrenalectomy (LA) is now considered the standard for treatment of surgically correctable adrenal disorders. Robotic adrenalectomy has been performed worldwide and has established itself as safe, feasible and effective approach. We hereby present the first study in robotic transperitoneal LA from Indian subcontinent. Materials and Methods: We conducted a retrospective evaluation of 25 patients who had undergone robotic assisted LA at a tertiary health centre by a single surgeon. Demographic, clinical, histopathological and perioperative outcome data were collected and analysed. Results: Mean age of the patients was 45 years (range: 27-65 years). Eleven male and 14 female patients were operated. Mean operative time was 139 min ± 30 min (range: 110-232 min) and mean blood loss was 85 ml ± 12 ml (range: 34-313 ml). Mean hospital stay was 2.5 ± 1.05 days (range: 2-6 days). Mean visual analogue scale score was 3.2 (range: 1-6) mean analgesic requirement was 50 mg diclofenac daily (range: 0-150 mg). Histopathological evaluation revealed 11 adenomas, eight phaeochromocytomas, two adrenocortical carcinomas, and four myelolipomas. According to Clavien-Dindo classification, three patients developed Grade I post-operative complications namely hypotension and pleural effusion. Conclusion: Robotic adrenalectomy is safe, technically feasible and comfortable to the surgeon. It is easier to perform with a short learning curve.

Background: Although numerous studies have been published on robotic adrenalectomy (RA) in the literature, none has done a comparison of posterior retroperitoneal (PR) and transabdominal lateral (TL) approaches. The aim of this study was to compare the outcomes of robotic PR and TL adrenalectomy.Methods: This is a retrospective analysis of a prospectively maintained database. Between September 2008 and January 2017, perioperative outcomes of patients undergoing RA through PR and TL approaches were recorded into an IRB-approved database. Clinical and perioperative parameters were compared using Student's t test, Wilcoxon rank-sum test, and χ 2 test. Multivariate regression analysis was performed to determine factors associated with total operative time.Results: 188 patients underwent 200 RAs. 110 patients were operated through TL and 78 patients through PR approach. Overall, conversion rate to open was 2.5% and 90-day morbidity 4.8%. The perioperative outcomes of TL and PR approaches were similar regarding estimated blood loss, rate of conversion to open, length of hospital stay, and 90-day morbidity. PR approach resulted in a shorter mean ± SD total operative time (136.3 ± 38.7 vs. 154.6 ± 48.4 min; p = 0.005) and lower visual analog scale pain score on postoperative day #1 (4.3 ± 2.5 vs. 5.4 ± 2.4; p = 0.001). After excluding tumors larger than 6 cm operated through TL approach, the difference in operative times persisted (136.3 ± 38.7 vs. 153.7 ± 45.7 min; p = 0.009). On multivariate regression analysis, increasing BMI and TL approaches were associated with longer total operative time.Conclusion: This study shows that robotic PR and TL approaches are equally safe and efficacious. With experience, shorter operative time and less postoperative pain can be achieved with PR technique. This supports the preferential utilization of PR approach in high-volume centers with enough experience. [ABSTRACT FROM AUTHOR]

The history of adrenal surgery is longstanding. Firstly described in 1889 by Thornton, the open adrenalectomy has been for decades the only surgical approach to adrenal diseases. Nowadays, instead, several approaches to adrenal glands have been described in the literature, such as laparoscopic adrenalectomy, robotic-assisted procedure and single-incision technique. Actually, laparoscopic adrenalectomy is considered as the gold standard treatment for adrenal lesions. In fact, all functional tumors, including pheochromocytoma, are candidates for a laparoscopic approach in the absence of other contraindications. In the adrenal gland surgery, it is important to consider that a multidisciplinary approach which comprises surgeons, anesthesiologists, endocrinologists, and oncologists plays an important role in the management of patients and that the success of the procedure is related also to surgeon experience and hospital volume. This review aims to discuss the indications for adrenalectomy and to describe the different techniques options for the adrenal gland surgery. [ABSTRACT FROM AUTHOR]

Background: The benefit of robotic adrenalectomy (RA) compared to laparoscopic adrenalectomy (LA) is still debatable. The purpose of this paper was to systematically review and synthesize all available evidence comparing RA to LA so as to evaluate which procedure provides superior clinical outcomes.Methods: A systematic literature search of PubMed and Scopus databases was performed with respect to the PRISMA statement (end-of-search date: January 31, 2016). Data on perioperative variables were extracted by three independent reviewers. Data were pooled using a random-effects model.Results: Twenty-seven studies were included in this review (13 comparative and 14 non-comparative). Overall, 1162 patients underwent adrenalectomy (747 treated with RA and 415 with LA). There was no significant difference between the robotic and the laparoscopic groups for intraoperative complications (OR: 1.20; 95%CI, 0.33-4.38), postoperative complications (OR: 0.69; 95% CI, 0.36-1.31), mortality (OR: 0.42; 95%CI, 0.07-2.72), conversion to laparotomy (OR: 0.51; 95%CI, 0.21-1.23), conversion to laparotomy or laparoscopy (OR: 0.73; 95%CI, 0.32-1.69) and blood loss (WMD: -9.78; 95%, -22.10 to 2.53). For patients treated with RA, there was a significantly shorter hospital stay (WMD: -0.40; 95% CI, -0.64 to -0.17) and a significantly longer operating time (WMD: 15.60; 95%CI, 2.12 to 29.08).Conclusions: Robotic adrenalectomy is a safe and feasible procedure with similar clinical outcomes as the laparoscopic approach in selected patient populations. High quality RCTs as well as uniform and detailed reporting of outcomes are needed to determine the role and cost-effectiveness of robotic adrenal surgery in the years to come.

Background: Laparoscopic adrenalectomy is currently considered the gold standard method for adrenal surgery. Open surgery is the most frequent technique preferred amongst surgeons who are faced with tumours of larger sizes or challenging lesions. Despite the increasing interest in laparoscopy, most centres still utilise open surgery for challenging adrenal cases., And Methods: We retrospectively evaluated our successive 30 robotic adrenalectomies performed in the past 10 years and assigned the patients into 'difficult' and 'easy' groups. Patients with malignant tumours or tumour size of over 8 cm were assigned to the 'difficult group' and others to the 'easy group'. Groups were evaluated according to the demographic features of the patients, side of the operation, the body mass index (BMI) and laparotomy history. The duration of anaesthesia, amount of bleeding during surgery and the hospitalisation periods were also evaluated., Results: There is no statistically significant difference between the two groups considering age, gender, BMI value, operation side, presence or absence of a laparotomy history, the amount of bleeding during the operation and hospitalisation duration (P > 0.05). The anaesthesia duration was found to be higher in the 'difficult' patient group (P < 0.05)., Conclusion: Our results present robust evidence to support the idea that robotic adrenalectomy is not only a doable but also a safe option for malignant and large adrenal masses., Competing Interests: None

Currently, most renal masses are detected incidentally while still small in size because of the widespread use of radiological imaging, and most pheochromocytomas are localized in the adrenal glands as unilateral lesions. A 5 x 4-cm right adrenal mass and a 19 x 13-mm exophytic left renal mass were synchronously detected by contrast enhancement on computed tomography and magnetic resonance imaging in a 47-year-old male with hypertension. The patient's preoperative serum and 24-h urine catecholamine levels were elevated. Initially, robotic transperitoneal right adrenalectomy was performed, and histopathology confirmed a 4 cm pheochromocytoma. After 3 months, transperitoneal zero ischemia robotic left partial nephrectomy was performed, and histopathology demonstrated clear cell renal cell carcinoma, Fuhrman grade II, 17 mm in size with clear surgical margins. This case indicates that sequential robotic surgery is feasible and safe as a minimally invasive approach to remove bilateral renal and adrenal masses. Zero ischemia robotic partial nephrectomy is also feasible and safe for selected small renal masses. [ABSTRACT FROM AUTHOR]
