Abstract
BACKGROUND Laparoscopic adrenalectomy is recognized as the "gold standard" approach for benign adrenal tumors. The majority of surgeons opt for laparoscopic transabdominal adrenalectomies (LTA), while retroperitoneoscopic adrenalectomies (RPA) in the prone position have certain advantages for patients. The aim of this study was to compare the effectiveness and safety of the transabdominal and retroperitoneoscopic laparoscopic adrenalectomies. MATERIALS AND METHODS Between 2000 and 2021, our clinic performed 472 laparoscopic adrenalectomies. The age ranged from 19 to 79 years, with a mean age of 50.5 ± 10.2 years. The patient pool consisted of 315 women and 157 men. Tumor sizes ranged from 1 to 10 cm. RESULTS In a study of 316 patients undergoing LTA versus 156 with RPA, the TLA averaged 82.5 min (70-98), while the RPA took 56.4 min (46-62) (P < 0.001). Intraoperative blood loss was 110 cc for the LTA group and 80 cc for the RPA group (P < 0.05) Conversion rates stood at 2.5% for transabdominal and 4.5% for retroperitoneoscopic procedures (P = 0.254). At 24 h post-operation, pain scores were 3.6 and 1.6, respectively (P < 0.001). Time to resume solid oral intake was 15.2 h for TLA and 8 h for RPA, with hospital stays at 4.5 days and 3 days respectively (P < 0.001). Short-term complications occurred in 8.9% of transabdominal and 12.2% of retroperitoneoscopic patients (P = 0.257). CONCLUSIONS For small tumors, RPA offers advantages over the transabdominal method in surgery time, blood loss, post-op pain, and recovery. These benefits are enhanced for patients with prior abdominal surgeries. However, large tumors present challenges in the retroperitoneal approach due to limited space and anatomical orientation. If complications emerge, surgeons can seamlessly switch to the LTA.

Retroperitoneal laparoscopic adrenalectomy for large adrenal tumors-analysis of tumor size and adverse events: a retrospective single-center study. Front Surg 2024; 10:1284093. [PMID: 38249307 PMCID: PMC10796556 DOI: 10.3389/fsurg.2023.1284093] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2023] [Accepted: 12/15/2023] [Indexed: 01/23/2024] Open
Abstract
Introduction Adrenal tumors are relatively common, and adrenalectomy is the third most common endocrine surgery. Patients with adrenal tumors were categorized into two groups for analysis: those with intermediate (4-6 cm, Group 1) and large (>6 cm, Group 2) tumors undergoing Retroperitoneal Laparoscopic Adrenalectomy (RLA). The primary outcome is to compare the surgical outcomes between these two groups. The secondary outcome involves analyzing the relationship between tumor characteristics and the incidence of adverse events. Methods Data from 76 patients who underwent RLA for tumors of size ≥4 cm between 2005 and 2022 at a single tertiary referral center were analyzed retrospectively. Variables, including patients' age, hormone function, operation time, conversion to open approach, perioperative complications, and adverse surgical events (blood loss >500 cc, conversion to open approach, and perioperative complications), were assessed. Results No significant differences were observed between the two groups in terms of functional and histopathologic analysis, gender distribution, functioning factors, perioperative complications, and estimated blood loss. However, patients in Group 2 were younger (median age 50, IQR: 40-57, P = 0.04), experienced longer operative times (median 175 min, IQR: 145-230 min, P = 0.005), and had a higher rate of conversion to open surgery (12%, P = 0.033). For every 1 cm increase in tumor size, the odds ratio for adverse surgical events increased by 1.58. Conclusions RLA is a safe and feasible procedure for adrenal tumors larger than 6 cm. While intraoperative and postoperative complications are not significantly increased in either group, larger tumors increase surgery times and are more likely to require conversion to open surgery. Therefore, caution and preparedness for potential adverse events are recommended when dealing with larger tumors. A tumor size of 5.3 cm may serve as a guide for risk stratification and surgical planning in large adrenal tumor management.

Abstract
BACKGROUND No randomised clinical trials (RCTs) have simultaneously compared the safety of open (OA), transperitoneal laparoscopic (TLA), posterior retroperitoneal (PRA), and robotic adrenalectomy (RA) for resecting adrenal tumours. AIM To evaluate outcomes for OA, TLA, PRA, and RA from RCTs. METHODS A NMA was performed according to PRISMA-NMA guidelines. Analysis was performed using R packages and Shiny. RESULTS Eight RCTs with 488 patients were included (mean age: 48.9 years). Overall, 44.5% of patients underwent TLA (217/488), 37.3% underwent PRA (182/488), 16.4% underwent RA (80/488), and just 1.8% patients underwent OA (9/488). The mean tumour size was 35 mm in largest diameter with mean sizes of 44.3 mm for RA, 40.9 mm for OA, 35.5 mm for TLA, and 34.4 mm for PRA (P < 0.001). TLA had the lowest blood loss (mean: 50.6 ml), complication rates (12.4%, 14/113), and conversion to open rates (1.3%, 2/157), while PRA had the shortest intra-operative duration (mean: 94 min), length of hospital stay (mean: 3.7 days), lowest visual analogue scale pain scores post-operatively (mean: 3.7), and was most cost-effective (mean: 1728 euros per case). At NMA, there was a significant increase in blood loss for OA (mean difference (MD): 117.00 ml (95% confidence interval (CI): 1.41-230.00)) with similar blood loss observed for PRA (MD: - 10.50 (95% CI: - 83.40-65.90)) compared to TLA. CONCLUSION LTA and PRA are important contemporary options in achieving favourable outcomes following adrenalectomy. The next generation of RCTs may be more insightful for comparison surgical outcomes following RA, as this approach is likely to play a future role in minimally invasive adrenalectomy.

Perception versus reality: A case-matched study assessing the intraoperative hemodynamics of minimally invasive retroperitoneal versus transperitoneal approach to pheochromocytomas. Surgery 2023; 173:653-658. [PMID: 36280508 DOI: 10.1016/j.surg.2022.06.056] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2022] [Revised: 06/15/2022] [Accepted: 06/27/2022] [Indexed: 11/07/2022]
Abstract
BACKGROUND Pheochromocytomas produce excess catecholamines that can result in intraoperative hemodynamic instability. Centers have reported variations in intraoperative hemodynamics with the retroperitoneoscopic versus the laparoscopic transperitoneal approach to adrenalectomies. When the retroperitoneoscopic approach was initiated for pheochromocytomas at our institution, the perception was of improved intraoperative hemodynamics, hypothesizing that increased retroperitoneoscopic insufflation pressures caused decreased venous return and less fluctuation in circulating catecholamines. The purpose of this study was to examine if a difference in intraoperative hemodynamics exists between a size-matched cohort of laparoscopic transperitoneal and retroperitoneoscopic pheochromocytoma patients. METHODS Unilateral adrenalectomies for pheochromocytoma performed via laparoscopic transperitoneal or retroperitoneoscopic approaches from 2015 to 2021 were identified from a surgical database. As larger tumors often underwent a laparoscopic transperitoneal approach, cases were matched 1:1 by tumor size. All patients received phenoxybenzamine. Groups were compared by patient characteristics, preoperative blockade, intraoperative hemodynamics and management, and early postoperative outcomes. RESULTS There were 13 laparoscopic transperitoneal adrenalectomy cases matched to 13 retroperitoneoscopic cases according to tumor size. Both groups (laparoscopic transperitoneal and retroperitoneoscopic) were similar for age (53 years), body mass index (28.5 vs 29.7), sex (69% female), and side (8 vs 7 right). There was no difference in preoperative 24-hour urine metanephrines/normetanephrines (9.9/8.0 vs 2.4/5.7 μmol/day). The phenoxybenzamine dose was similar in both groups (112 vs 114 mg/24 hours), as were baseline heart rate, blood pressure, and mean arterial pressure. There was no difference in any intraoperative hemodynamic parameters or vasoactive interventions. Operative time, length of stay, and 30-day emergency visits were similar between groups. CONCLUSION This matched cohort study did not find a difference in intraoperative hemodynamics between laparoscopic transperitoneal and retroperitoneoscopic adrenalectomy approaches for pheochromocytoma in appropriately selected and blocked patients.

Abstract
Objectives To compare the efficacy and safety of retroperitoneal laparoscopic adrenalectomy (RLA) and transperitoneal laparoscopic adrenalectomy (TLA) in the treatment of large (≥6cm) adrenal pheochromocytomas. Methods We retrospectively collected the clinical data of 130 patients with large pheochromocytoma who underwent RLA or TLA in our hospital from 2012 to 2022. The perioperative parameters and follow-up outcomes of the two groups were compared, and univariate and multivariate analyses were used to evaluate the risk factors of hemodynamic instability (HI). Results A total of 57 patients underwent TLA and 73 underwent RLA. There was no difference in demographic characteristics such as age, sex and tumor size between the two groups. Compared with the TLA group, patients in the RLA group had shorter operation time (P<0.001) and less estimated blood loss (EBL) (P<0.001). The time to ambulation, time to oral food and time to removal of drainage of RLA group were earlier than those of TLA group. In addition, the hospital stay was shorter in the RLA group than in the TLA group. There were no differences in HI, complications, or blood pressure (BP) improvement between the two groups. The mean follow-up time was 61.4 and 65.5 months, respectively, during which no tumors recurred or metastasized. Multivariate analysis showed that elevated hormone levels and larger tumor size were independent risk factors for HI. Conclusions Both RLA and TLA are effective treatment methods for large pheochromocytomas, but the perioperative outcomes of RLA are better than that of TLA. Our study demonstrates the superiority of RLA for the treatment of large pheochromocytomas.

Abstract
Objective Clinical practice guidelines recommend open adrenalectomy (OA) for large pheochromocytoma (LPCC) > 6 cm in size. Although laparoscopic adrenalectomy (LA) for the treatment of LPCC has been reported, its role remains unclear. This study aimed to compare the effectiveness of LA and OA, and summary the surgical treatment experience. Methods Data concerning LPCC, from January 2010 to June 2019 of a single institution, were retrospectively reviewed. Altogether 82 patients with a tumor larger than 6 cm were included (52 patients in LA group and 30 patients in OA group). Groups were balanced by propensity score matching (PSM) into 15 pairs. Patients’ demographics, preoperative characteristics, and prognosis were analyzed. Results Before PSM, the OA group had larger tumor sizes (median [interquartile range, IQR]: 8.9 [7.3–10.3] vs. 7.2 [6.7–8.0] cm; p=0.000) and higher vanillylmandelic acid level (median [IQR]: 114.3 [67.8–326.4] vs. 66.6 [37.8–145.8] μmol/24 h; p =0.004) and needed a higher cumulative dose of prazosin (median [IQR]: 83.5 [37.0–154.0] vs. 38.0 [21.0–81.0] mg; p=0.028). After PSM, the baseline data showed no significant differences between both groups. The LA group had relatively more stable blood pressure in surgery, with a lower fluctuation of systolic blood pressure (mean±standard deviation [SD]: 70.9±25.1 vs. 107.4±46.2 mmHg, p=0.012) and a lower percentage of hemodynamic instability (46.7% vs. 86.7%, p=0.020). The LA group had shorter postoperative hospital stays (mean±SD: 6.4±2.7 vs. 10.1±3.4 days; p=0.003) than the OA group. Differences regarding metastasis rate (6.7% vs. 0, p=1.000) were not statistically significant between LA and OA groups. The median (IQR) follow-up time of 82 patients was 72.5 (47.0–103.5) months. Binary logistic regression showed that right-side tumors or those >8 cm in size were independent risk factors of OA. Conclusion LA is a safe, minimally invasive procedure for LPCC and has relatively better perioperative characteristics in large medical centers. Patients with tumors on the right side or larger than 8 cm are more likely to undergo OA initially.

Abstract
Background There is a lack of data regarding the appropriateness of transperitoneal and retroperitoneal approaches for homolateral laparoscopic adrenalectomy. The aim of this study is to compare lateral transperitoneal and retroperitoneal approach for left-sided and right-sided laparoscopic adrenalectomy respectively. Methods Between January 2014 and December 2019, 242 patients underwent left-sided and 252 patients underwent right-sided laparoscopic adrenalectomy. For left side, transperitoneal approach was used in 132 (103 with tumors < 5 cm and 29 with tumors ≥ 5 cm) and retroperitoneal approach in 110 (102 with tumors < 5 cm and 8 with tumors ≥ 5 cm). For right side, transperitoneal approach was used in 139 (121 with tumors < 5 cm and 18 with tumors ≥ 5 cm) and retroperitoneal approach in 113 (102 with tumors < 5 cm and 11 with tumors ≥ 5 cm). Patient characteristics and perioperative outcomes were recorded. For each side, both approaches were compared for tumors < 5 cm and ≥ 5 cm respectively. Results For left-sided tumors < 5 cm, transperitoneal approach demonstrated shorter operative time, less blood loss and longer time to oral intake. For left-sided tumors ≥ 5 cm, the peri-operative data of both approaches was comparable. For right-sided tumors < 5 cm, transperitoneal approach demonstrated shorter operative time and less blood loss. For right-sided tumors ≥ 5 cm, the peri-operative data was comparable. Conclusions Lateral transperitoneal and retroperitoneal approach are both effective for laparoscopic adrenalectomy. Lateral transperitoneal approach is faster with less blood loss for tumors < 5 cm.

Abstract
As a surgical method for the treatment of adrenal surgical diseases, laparoscopy has the advantages of small trauma, short operation time, less bleeding, and fast postoperative recovery. It is considered as the gold standard for the treatment of adrenal surgical diseases. Retroperitoneal laparoscopy is widely used because it does not pass through the abdominal cavity, does not interfere with internal organs, and has little effect on gastrointestinal function. However, complex adrenal tumors have the characteristics of large volume, compression of adjacent tissues, and invasion of surrounding tissues, so they are rarely treated by retroperitoneal laparoscopy. In recent years, with the development of laparoscopic technology and the progress of surgical technology, robotic surgery has been gradually applied to the surgical treatment of complex adrenal tumors. This paper reviews the clinical application of retroperitoneal laparoscopic surgery and robotic surgery in the treatment of complex adrenal tumors.

Abstract
Purpose Surgery is the major treatment option for pheochromocytoma but carries potential risks, including hemorrhage and hemodynamic instability. Even with laparoscopic adrenalectomy, intraoperative blood transfusion happens from time to time, but few studies have investigated risk factors. For the first time we develop and validate a nomogram for prediction of red blood cell transfusion in pheochromocytoma surgery. Methods There were 246 patients in our center and 56 patients in Peking Union Medical College Hospital, who underwent pheochromocytoma surgery, enrolled in the study. We incorporated clinical and radiological risk factors, and presented this with a nomogram. Lasso regression model was used for feature selection. Logistic regression analysis was performed to identify the odd ratios. The performance of the nomogram was assessed with respect to its discrimination, calibration and clinical usefulness. Results Thirty-two features were reduced to five, which were phenoxybenzamine use, phenoxybenzamine treatment duration, preinduction heart rate, tumor diameter and surgical procedure. The model showed good discrimination (C-index, 0.857; 95% CI, 0.781-0.836) and application in the validation sets also gave good discrimination (internal validation: C-index, 0.831; 95% CI, 0.750-0.822; external validation: C-index, 0.924; 95% CI, 0.766-1.000). Calibration tested with the Hosmer-Lemeshow test yielded a good agreement between prediction and observation (training P=0.358; internal validation P=0.205; external validation P=0.395). Odd ratios of phenoxybenzamine use, phenoxybenzamine treatment duration, preinduction HR, tumor diameter and open surgery were 13.32 (95% CI, 1.48-197.38; P = 0.034), 1.04 (95% CI, 0.99-1.08; P = 0.092), 1.04 (95% CI, 1.01-1.08; P=0.006), 1.03 (95% CI, 1.02-1.06; P<0.001), 17.13 (95% CI, 5.18-78.79; P<0.001), respectively. Decision curve analysis demonstrated the clinical usefulness of the nomogram. Conclusions This study presents a nomogram that may be used to facilitate the prediction of red blood cell transfusion in pheochromocytoma surgery and help to do the preoperative management more efficiently.

Comparison of robot-assisted retroperitoneal laparoscopic adrenalectomy versus retroperitoneal laparoscopic adrenalectomy for large pheochromocytoma: a single-centre retrospective study. BMC Surg 2020; 20:227. [PMID: 33028297 PMCID: PMC7539373 DOI: 10.1186/s12893-020-00895-5] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2020] [Accepted: 09/29/2020] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND To evaluate the feasibility and safety of robot-assisted retroperitoneal laparoscopic adrenalectomy (RARLA) for large pheochromocytomas (PHEOs; size≥6 cm) compared with retroperitoneal laparoscopic adrenalectomy (RLA). METHODS Fifty-one patients who underwent adrenalectomy for large PHEOs between March 2016 and January 2019 were enrolled and divided into two groups, including 32 RLA cases and 19 RARLA cases. We compared the perioperative efficacy and long-term follow-up results between the two groups. RESULTS Preoperative data, including demographics, comorbidities and tumour characteristics, were similar between the groups. Intraoperatively, the RARLA group had a lower incidence of haemodynamic instability (26.3% vs. 56.2%, P = 0.038) and less intraoperative blood loss (100 ml vs. Two hundred milliliter, P = 0.042) than the RLA group. The groups showed no significant differences in operative time or transfusion rates. Postoperatively, the time to diet resumption, time to ambulation, time to drainage removal and postoperative hospital stay were shorter in the RARLA group than in the RLA group (1 d vs. 2 d, P = 0.027; 1 d vs. 2 d, P = 0.034; 3 d vs. 5 d, P = 0.002; 5 d vs. 6 d, P = 0.02, respectively). The groups exhibited no significant differences in the duration of anaesthetic use, complications, or long-term follow-up results for the blood pressure (BP) improvement rate. CONCLUSIONS Compared with RLA, RARLA is a safe, feasible and even optimized procedure for large PHEOs.

Abstract
STUDY OBJECTIVES Compare the rates of major intra- and postoperative complications, surgical conversion and mortality between transperitoneal versus retroperitoneal laparoscopic adrenalectomy. PATIENTS AND METHODS In a series of 344 consecutive unilateral laparoscopic adrenalectomies, performed from January 1997 to December 2017, we evaluated the rates of major intra- and postoperative complications (Clavien-Dindo≥III) and surgical conversion of the two approaches. RESULTS The retroperitoneal laparoscopic route was used in 259 patients (67.3%) and the transperitoneal laparoscopic route in 85 patients (22.1%). A total of 12 (3.5%) major postoperative complications occurred, with no statistically significant difference between the two approaches (P=0.7). In univariate analysis, the only predictor of major postoperative complication was Cushing's syndrome (P=0.03). The surgical conversion rate was higher in the transperitoneal route group (10/85 (11.8%) compared to 6/259 (2.3%), P=0.0003) in the retroperitoneal route group. One death occurred in each group. Independent predictors of surgical conversion in multivariate analysis included the transperitoneal laparoscopic approach (OR 1.7, 95% CI 1.3-1.9, P=0.02), advanced age (OR 1.2, 95% CI 1.1-1.6, P=0.04) and large tumor size (OR 1.3, 95% CI 1.1-1.7, P=0.01). CONCLUSION Both transperitoneal and retroperitoneal approaches for laparoscopic adrenalectomy are safe, with an equivalent rate of major complications and mortality. The surgical conversion rate was higher for the transperitoneal route. The retroperitoneal approach should be reserved for small adrenal lesions.

Abstract
Objectives: Currently, laparoscopic adrenalectomy is the gold standard technique for suitable patients with adrenal masses. In this study, we aimed to assess the postoperative results of patients who underwent laparoscopic adrenalectomy. Methods: Between January 2014 and October 2019, 76 cases were operated and retrospectively evaluated. Laparoscopic transabdominal adrenalectomy was applied to the patients. Demographic profiles, preoperative indications, intraoperative and postoperative complications, mortality and length of hospital stay were evaluated. Results: Seventy-six patients (30 male, 46 female) with a mean age of 47.2±11.7 (range 22-71) years underwent laparoscopic adrenalectomy. Thirty-nine of the patients had right; 33 of the patients had left adrenal masses. Three patients had bilateral adrenal cortical hyperplasia. One patient was operated for paraganglioma. Conversion to open adrenalectomy was observed in four patients (5.26%). Nine patients (11.8%) experienced intraoperative and postoperative complications. Intraoperative and postoperative complications were bleeding from spleen (2 cases) and upper pole of kidney (1 case), renal artery injury (1 case), bleeding from liver parenchyma (2 cases), ischemia of spleen and pancreas (1 case), small intestinal injury (1 case) and incisional hernia (1 case). The complication rate is acceptable and comparable with other studies in the literature. Conclusion: Laparoscopic adrenalectomy can be safely applied in suitable patients with acceptable complications and low conversion rates.

Abstract
Purpose To compare surgical outcomes between the lateral and the posterior approach for retroperitoneal laparoscopic adrenalectomy (RLA). Materials and Methods We retrospectively reviewed the records of 130 patients who underwent RLA for adrenal tumors by a single surgeon between January 2015 and December 2018. Patient characteristics and perioperative outcomes were analyzed and compared between two surgical groups: lateral approach (n=56) and posterior approach (n=74). Results There were no significant differences in perioperative outcomes between the two groups except for operative time (lateral approach, 105.4±41.21 minutes vs. posterior approach, 71.5±31.51 minutes; p=0.001). In the lateral approach group, two patients (3.6%) underwent open conversion, but there were no major complications in either group (Clavien-Dindo classification ≥3). Male sex was associated with an operative time of ≥90 minutes in the univariate analysis (p=0.019), but this effect did not remain significant in the multivariate analysis. In the multivariate analysis, large tumor size (>5 cm; p=0.020) and preoperative diagnosis of malignancy (p=0.043) were significantly associated with an operative time of ≥90 minutes. Conclusions Both the lateral and posterior approaches for RLA were performed safely with similar operative outcomes and are therefore comparable options for the treatment of adrenal tumors. In addition, large tumor size and preoperative diagnosis of malignancy are associated with longer operative times.

Laparoscopic transperitoneal and retroperitoneal adrenalectomy: a 20-year, single-institution experience with an analysis of the learning curve and tumor size [lap transper and retroper adrenalectomy]. Surg Endosc 2020; 34:5421-5427. [PMID: 31953726 PMCID: PMC7644518 DOI: 10.1007/s00464-019-07337-1] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2019] [Accepted: 12/24/2019] [Indexed: 12/13/2022]
Abstract
BACKGROUND The superiority of laparoscopic transperitoneal (TP) versus retroperitoneal (RP) adrenalectomy is an ongoing debate. METHODS Data from 163 patients (TP: n = 135; RP: n = 28) undergoing minimally invasive adrenalectomy were analyzed. Both operative [intraoperative blood loss, previous abdominal surgery, conversion rate, operative time and tumor size] and perioperative [BMI (body mass index), ASA (American Society of Anesthesiologists) score, time of hospitalization, time of oral intake, histology and postoperative complications] parameters were compared. Both the learning curve (LC) and tumor size were analyzed. RESULTS We found significant differences in the mean operative time (p = 0.019) and rate of previous abdominal surgery (p = 0.038) in favor of TP. Significantly larger tumors were removed with TP (p = 0.018). Conversion rates showed no significant difference (p = 0.257). Also, no significant differences were noted for time of hospitalization, intraoperative blood loss and postoperative complications. In terms of the LC, we saw significant differences in previous abdominal surgery (p = 0.015), conversion rate (p = 0.011) and operative time (p = 0.023) in favor of TP. Large (LT) and extra-large tumors (ELT) were involved in 47 lesions (LT: 40 vs. ELT: 7), with a mean tumor size of 71.85 and 141.57 mm, respectively. Mean intraoperative blood loss was 64.47 ml vs. 71.85 ml, time of hospitalization was 5.10 vs. 4.57 days and mean operative time was 76.52 vs. 79.28 min for LT and ELT, respectively. CONCLUSION A shorter operative time and lower conversion rate in favor of TP were noted during the learning curve. TP proved to be more effective in the removal of large-, extra-large and malignant lesions. The RP approach was feasible for smaller, benign lesions, with a more prolonged learning curve.

Abstract
Background To compare the perioperative outcomes and safety of transperitoneal laparoscopic adrenalectomy with those of retroperitoneal laparoscopic adrenalectomy for patients with pheochromocytoma. Methods We searched PubMed, EMBASE and the Cochrane Central Register for studies from 1999 to 2019 to assess the perioperative outcomes and safety of transperitoneal laparoscopic adrenalectomy and the retroperitoneal approach for laparoscopic adrenalectomy in patients with pheochromocytoma. After data extraction and quality assessments, we used RevMan 5.2 to pool the data. Results Four retrospective studies were obtained in our meta-analysis. Patients who underwent retroperitoneal laparoscopic adrenalectomy were associated with shorter operative time (WMD: 34.91, 95% CI: 27.02 to 42.80, I2 = 15%; p < 0.01), less intraoperative blood loss (WMD: 139.32, 95% CI: 125.38 to 153.26, I2 = 0, p < 0.01), and a shorter hospital stay (WMD: 2, 95% CI: 1.18 to 2.82, I2 = 82%, p < 0.01) than patients who underwent transperitoneal laparoscopic adrenalectomy. No significant differences were found in the complication rate (OR: 1.58, 95% CI: 0.58 to 4.33, I2 = 0; p = 0.38) or in the incidence of hemodynamic crisis (OR: 0.74, 95% CI: 0.19 to 2.94, p = 0.67) between the two groups. Conclusion Retroperitoneal laparoscopic adrenalectomy could achieve better perioperative outcomes than the transperitoneal approach for patients with pheochromocytoma.

Abstract
Background It remains unclear whether retroperitoneal laparoscopic adrenalectomy (RLA) is safe and effective for the treatment of large pheochromocytoma (PHEO). This retrospective study aimed to identify the advantages and disadvantages of RLA compared to open adrenalectomy (OA). Methods This study included 147 patients who underwent RLA (n = 101) or OA (n = 46) for PHEO larger than 5 cm. Groups were balanced by propensity score matching (PSM) into 46 pairs. Perioperative variables and long-term follow-up results were compared between the two groups. Results After PSM, patients in the RLA group had a shorter operative time (218 vs. 245 min, P = 0.040), quicker bowel recovery (2 vs. 3 days, P = 0.046), and a shorter hospital stay (8 vs. 9 days, P = 0.010) compared to the OA group. The results of multiple linear regression analyses showed that the operative method (OA vs. RLA) had an influence on the above three postoperative variables (β = 31.84, P = 0.046; β = 0.76, P = 0.044; and β = 1.25, P = 0.025, respectively). There was no significant difference in the proportion of patients with improved blood pressure (82.61% vs. 69.57%, P = 0.143) between the two groups. Conclusions Both RLA and OA provide similar perioperative and long-term outcomes for the surgical management of large PHEO. RLA is an efficacious and safe surgical method for patients with PHEO larger than 5 cm in diameter.

Abstract
Introduction Paragangliomas have a rich blood flow and are located around large vessels; thus, resection is often difficult. We herein report a case of a paraganglioma that was located immediately behind the inferior vena cava and bilateral renal veins and successfully resected by laparoscopic surgery. Case presentation A 72‐year‐old man was incidentally diagnosed with a 7‐cm retroperitoneal mass immediately behind the inferior vena cava and bilateral renal veins by computed tomography. The mass was diagnosed as a retroperitoneal paraganglioma. The patient underwent laparoscopic surgery in the left lateral decubitus position. The tumor was dissected completely with no complications. Conclusion Resection of retroperitoneal paragangliomas is often a surgical challenge. The feasibility of the laparoscopic approach to such paragangliomas was demonstrated in the present case.
