Abstract
OBJECTIVES Laparoscopic adrenalectomy has been the gold standard surgical procedure. However, the adaptation criteria for malignant tumors and predictors of perioperative outcomes are not well defined. Therefore, this study tried to identify valid predictors for perioperative outcomes of laparoscopic adrenalectomy and consider the adaptation criteria. METHODS We retrospectively reviewed the preoperative and perioperative data of 216 patients who underwent transperitoneal laparoscopic adrenalectomy in our hospital. Preoperative factors associated with perioperative outcomes were analyzed using multiple regression analysis. RESULTS Among 216 patients, 165 (76.4%), 26 (12.0%), and 25 (11.6%) were suspected of having benign tumors, pheochromocytoma, and malignant tumors, respectively. Median tumor size was 25.0 mm (interquartile range 18.0-35.0); median perirenal fat thickness was 9.2 mm (interquartile range 4.9-15.6) on preoperative computed tomography scans. The median operative time was 145.5 min (interquartile range 117.5-184.0) and the median estimated blood loss was 0.0 mL (interquartile range 0.0-27.3). Perirenal fat thickness (p < 0.001), tumor size (p < 0.001), and malignant tumors (p = 0.020) were associated with operative time, and perirenal fat thickness (p = 0.038) and malignant tumors (p = 0.002) were associated with estimated blood loss. CONCLUSIONS Perirenal fat thickness, tumor size, and malignant tumors are valid predictors of the surgical outcomes of transperitoneal laparoscopic adrenalectomy. As only perirenal fat thickness is associated with both surgical outcomes except for malignant tumors, it is a powerful predictor. Transperitoneal laparoscopic adrenalectomy for large malignant adrenal tumors with thick perirenal fat should be performed with caution.

Abstract
BACKGROUND The present study aimed to evaluate the safety and efficacy of transperitoneal laparoscopic adrenalectomy (LA) for large adrenal tumours by comparing the outcomes of tumours larger than 6 cm with those smaller than 6 cm and also to identify the risk factors associated with prolonged operative time in transperitoneal LA. PATIENTS AND METHODS One hundred and sixty-three patients underwent LA at our clinic from January 2014 to December 2020. Bilateral LA was performed in 20 of these 163 patients. A total of 143 patients were included in this study. Data were analysed retrospectively from the patients' medical records collected. RESULTS Large tumour (LT) group consists of 33 patients and the small tumour (ST) group consists of 110 patients. There was no statistically significant difference between the groups regarding conversion to open surgery and complications. A multiple regression analysis was conducted to identify the independent predictors of prolonged operation time. The tumour size ≥8 cm (odds ratio [OR], 19.132; 95% confidence interval [CI], 3.881-94.303; P < 0.001) and diagnosis of pheochromocytoma (OR, 2.762; 95% CI, (1.123-6.789, P = 0.026) were the significant predictors of prolonged operation time. CONCLUSION Our study shows that LA can be considered the treatment of choice for small and large adrenal tumours. The tumour size ≥8 cm and diagnosis of pheochromocytoma are the independent risk factors for the prolonged operative time in transperitoneal LA.

Abstract
BACKGROUND Laparoscopic adrenalectomy (LA) is the gold standard for the resection of most adrenal lesions. A precise delineation of factors influencing its outcomes is lacking. The aim of this study was to assess factors associated with intraoperative complications, postoperative complications, and prolonged length of stay (LOS) after LA. METHODS Patients who underwent LA from 1999 to 2021 in a single-academic-institution were included. Patient and disease-specific data, intraoperative complications, postoperative complications according to Dindo-Clavien (DC) scale, and LOS were recorded. Predictive factors of complications and prolonged LOS were determined by logistic regression. RESULTS We identified 530 patients who underwent 547 LA. Intraoperative complications occurred in 33 patients (6.0%). Postoperative complications ≥ DC grade 2 occurred in 73 patients (13.35%); severe postoperative complications ≥ DC grade 3 in 14 patients (2.56%). Postoperative complications were positively associated with age ≥ 72 (OR 1.14 [95% CI 1.02-1.29]), intraoperative complications (OR 1.36 [95% CI 1.14-1.63]), and negatively associated with non functional adenomas (OR 0.88 [95% CI 0.7-0.99]), and right adrenalectomy (OR 0.91 [95% CI 0.86-0.97]). Severe postoperative complications were positively associated with chronic obstructive pulmonary disease (COPD, OR 1.08 [95% CI 1.00-1.17]), and negatively associated with right adrenalectomy (OR 0.97 [95% CI 0.92-0.99]). Prolonged LOS was associated with age ≥ 72 (OR 1.21 [95% CI 1.05-1.41]), and COPD (OR 1.20 [95% CI 1.01-1.44]). CONCLUSIONS LA remains safe when performed by surgeons with expertise. Right adrenalectomy resulted in less postoperative overall and severe complications. The risk-benefit equation should be carefully assessed before left LA in older patients with COPD.

Analysis of risk factors for conversion in laparoscopic adrenalectomy: a single-institution series of 256 patients. Wideochir Inne Tech Maloinwazyjne 2023; 18:453-459. [PMID: 37868277 PMCID: PMC10585466 DOI: 10.5114/wiitm.2023.126446] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2022] [Accepted: 02/24/2023] [Indexed: 10/24/2023] Open
Abstract
Introduction Although introduction of the laparoscopic approach for adrenal gland surgery revolutionized the strategy in management of adrenal gland tumors, open surgery is still a method of choice in some clinical scenarios. Moreover, laparoscopy may have limitations resulting in conversion. Aim To assess risk factors predisposing for conversion based on our own material, including 256 laparoscopic adrenalectomies performed in 2009-2016. Material and methods A retrospective analysis of patients who underwent adrenalectomies between 2009 and 2016 was conducted. Patients were analyzed for sex, body mass index (BMI), size of the adrenal gland lesion, final histopathological diagnosis and operated side of the adrenal gland, its impact on conversion rate. Results A total of 256 patients underwent laparoscopic adrenalectomy. The reported study comprised of 94 (36.7%) men and 162 (63.3%) women. The most common indication for adrenalectomy were adrenal cortex adenoma (n = 149; 58.2%) and pheochromocytoma (n = 48; 18.75%). The conversion rate was 3.91% (n = 10 patients). Mean BMI of patients without conversion was 27.6 kg/m2, whereas in the group of patients with conversion, BMI was 29.7 kg/m2 (p > 0.05). The conversion rate was precisely the same when comparing the right (5/126; 3.9%) and left (5/126; 3.9%) adrenal gland. There was no correlation between the size of the adrenal lesion and the risk of conversion. Conclusions The laparoscopic approach remains an efficient and safe procedure for adrenal gland tumors. Based on our study, obese patients and those with pheochromocytoma are associated with a higher risk of conversion but without any statistical significance. There was no difference in the conversion rate when analyzing the size of the adrenal gland tumor. No difference was also revealed in the conversion rate when comparing both sides of laparoscopic adrenalectomy.

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.

New predictive factors for prolonged operation time of laparoscopic posterior retroperitoneal adrenalectomy; retrospective cohort study. Int J Surg 2021; 94:106113. [PMID: 34534705 DOI: 10.1016/j.ijsu.2021.106113] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2021] [Revised: 08/29/2021] [Accepted: 09/11/2021] [Indexed: 11/21/2022]
Abstract
BACKGROUND Laparoscopic adrenalectomy is a standard surgical procedure for benign adrenal diseases. Laparoscopic posterior retroperitoneal adrenalectomy (LPRA) has many benefits. However, it is associated with factors such as prolong operation time. The aim of the study was to determine the predictive factors associated with prolonged operation time in LPRA. MATERIALS AND METHODS This study retrospectively analyzed data from 284 patients who underwent LPRA between 2014 and 2019 at Asan Medical Center. Then, we analyzed the predictive factors prolonging operation time using multivariate logistic regression analysis and classified the differences according to the learning curve using cumulative sum analysis. RESULTS In multivariate logistic regression analysis, the following were determined as factors associated with prolonged operation time: male sex (OR, 2.540; 95% CI, 1.225-5.266), pheochromocytoma (OR, 3.669; 95% CI, 1.548-8.694), right site (OR, 2.499; 95% CI, 1.086-5.748), surgeon A (OR, 3.293; 95% CI, 1.522-7.122), depth of descended adrenal tumor location to kidney (OR, 3.793; 95% CI, 1.660-8.667), large periadrenal fat volume (OR, 2.366; 95% CI, 1.120-4.996), and posterior adiposity index (PAI) (OR, 2.171; 95% CI, 1.090-4.324) (all p < 0.05). However, in the period after the learning curve, periadrenal fat volume was not a significant predictor of surgery time prolongation. CONCLUSION This study demonstrates that depth of descended adrenal tumor location to kidney is a new and important independent predictive factor for prolonged operation time in LPRA. In addition, periadrenal fat volume is a predictor of surgery time prolongation for beginner surgeons before the learning curve.

Abstract
Adrenal myelolipoma (AML) is a rare benign tumor, usually non-functioning and asymptomatic until it reaches large size. AML is mostly detected incidentally by imaging and is composed of adipose tissue and hematopoietic elements. Only symptomatic tumor needs surgical excision. We report the case of a large non-functioning adrenal tumor discovered by means of combined imaging techniques in a middle-aged male patient who complained the sudden onset of severe lower back pain; successful laparoscopic removal was performed, and AML was diagnosed at histopathology.

Abstract
Background: We aimed to compare the results of patients who underwent laparoscopic adrenalectomy (LA) for masses ≥6 cm versus <6 cm in diameter in our tertiary referral university hospital. Materials and Methods: Three hundred thirty consecutive patients were divided into two groups according to tumor size (≥6 and <6 cm in diameter). Demographic variables, body mass index (BMI), lesion localization (right/left), tumor diameter, pathological diagnosis and surgical outcomes, including operation time, estimated blood loss (EBL), conversion to open surgery, complications, and length of hospital stay were compared between groups. Results: Between February 2008 and March 2020, 53 patients (29 male-24 female) with ≥6 cm (L group) adrenal tumor and 277 patients (105 male-172 female) with <6 cm tumor (S group) underwent transperitoneal LA. One hundred sixty-eight (50.9%) tumors localized on the left side. In L group mean tumor size in female and male patients was 87.5 ± 40.8 mm (range 50-225 mm) and 67.3 ± 18.4 mm (range 10-100 mm), respectively (P < .05). Age, American Society of Anesthesiology scores, BMI, and mean operation time were similar between groups (P > .05). Postoperative complications were more often in L group (P = .005). EBL in group L and group S was 86 ± 70.4 mL (range 10-500 mL) and 55 ± 44.2 mL (range 10-300 mL), respectively (P = .003). Length of hospital stay in group L and group S was 3.7 ± 3.5 days (range 1-26) and 3 ± 1.6 days (range 1-9), respectively (P = .086). Significant variables in multivariate analysis, including gender (male), EBL, and postoperative complication rate, were entered into multivariate regression analysis, which presented that EBL and postoperative complication rates were independent significants for the L group. Conclusion: Six centimeters should not be considered as an upper limit of transperitoneal lateral LA and may be safely performed in centers with experience. Further studies are needed to confirm our data.
