Laparoscopic approaches to adrenalectomy for large adrenal tumours: a systematic review (original) (raw)

Applicability of laparoscopic approach to the resection of large adrenal tumours: a retrospective cohort study on 200 patients

Surgical endoscopy, 2015

Controversies exist in the best surgical approach (open vs. laparoscopy) to large adrenal tumours without peri-operative evidence of primary carcinoma, mainly due to possible capsular disruption of an unsuspected malignancy. In addition, intra-operative blood loss, conversion rate, operative time, and hospital stay may be increased with laparoscopy. (1) to compare clinical outcomes of laparoscopic adrenalectomy for large versus small adrenal tumours and (2) to identify risk factors associated with increased operative time and hospital stay in laparoscopic adrenalectomy. This is a multicentre retrospective cohort study in a large patient population (N = 200) who underwent laparoscopic adrenalectomy in 2004-2014 at three Italian academic hospitals. Patients were divided into two cohorts according to tumour size: "large" tumours were defined as ≥5 cm (N = 50) and "small" tumours as <5 cm (N = 150). Further analysis adopting a ≥8 cm (N = 15) cut-off size was perfo...

Laparoscopic Adrenalectomy for Large Adrenal Tumors

Journal of Endourology, 2005

Laparoscopic treatment of large adrenal tumors is still questionable due to concern over the risk of malignancy as well as the technical difficulties. No exact dimensional cutoff has been described for laparoscopic adrenalectomy (LA). In this study, we reviewed our experience with LA for masses ! 8 cm and tried to determine the limitations of this surgery in this group of patients. Sixteen patients with adrenal mass ! 8 cm (Group 1) and 19 patients with adrenal mass < 8 cm (Group 2) treated with transabdominal LA were included in this study. We analyzed operative time, intraoperative and postoperative complications and length of postoperative hospital stay with respect to tumor size and clinopathologic features. Mean maximum tumor diameters were 91.7 mm (range, 80e150 mm) and 52.4 mm (range, 35 e73 mm) in Group 1 and Group 2, respectively. Operation time and blood loss were higher in Group 1 compared to Group 2, but these differences did not reach significant levels (p > 0.05). Conversion to an open procedure required in two patients, one from each group, because of the firm attachments of adrenal mass to the surrounding tissue. In conclusion, our study demonstrated that LA is a safe and feasible procedure for large lesions even up to 15 cm. The risk of finding incidental adrenal cortical cancer was significantly increased for large lesions in our series as in the literature; therefore, it is important to follow the strict oncological principles in these cases.

Safety and feasibility of laparoscopic adrenalectomy: What is the role of tumour size? A single institution experience

Journal of Minimal Access Surgery, 2014

Although, there are studies in the literature having shown the feasibility and safety of laparoscopic adrenalectomy, there are still debates for tumour size and the requirement of the minimal invasive approach. Our hypothesis was that the use of laparoscopy facilitates minimally invasive resection of large adrenal tumours regardless of tumour size. Materials and Methods: Within 7 years, 149 patients underwent laparoscopic adrenalectomy at one institution. The patients were divided into two study groups according to tumour size. Group 1 included patients with adrenal tumours smaller than 5 cm and group 2 included larger than 5 cm. Patient demographics and clinical parameters, operative time, complications, hospital stay and final pathology were analysed. Statistical analyses of clinical and perioperative parameters were performed using Student's t-test and Chi-square tests. RESULTS: There were 88 patients in group 1 and 70 in group 2. There were no significant differences between study groups regarding patient demographics, operative time, hospital stay, and complications. Estimated blood loss was significantly higher in group 2 (P = 0.002). The conversion to open rate was similar between study groups with 5.6% versus 4.2%, respectively. Pathology was similar between groups. CONCLUSION: Our study shows that the use

Laparoscopic Resection of Large Adrenal Tumors

Annals of Surgical Oncology, 2002

Background: Laparoscopic adrenalectomy has rapidly replaced open adrenalectomy as the procedure of choice for benign adrenal tumors. It still remains to be clarified whether the laparoscopic resection of large (Ն8cm) or potentially malignant tumors is appropriate or not due to technical difficulties and concern about local recurrence. The aim of this study was to evaluate the short-and long-term outcome of 174 consecutive laparoscopic and open adrenalectomies performed in our surgical unit. ⌴ethods: Our data come from a retrospective analysis of 174 consecutive adrenalectomies performed on 166 patients from May 1997 to December 2008. Fifteen patients with tumors Ն8cm underwent laparoscopic adrenalectomy. Sixty-five patients were men and 101 were women, aged 16 years to 80 years. Nine patients underwent either synchronous or metachronous bilateral adrenalectomy. Tumor size ranged from 3.2cm to 27cm. The largest laparoscopically excised tumors were a ganglioneuroma with a mean diameter of 13cm and a myelolipoma of 14cm. Results: In 135 patients, a laparoscopic procedure was completed successfully, whereas in 14 patients the laparoscopic procedure was converted to open. Seventeen patients were treated with an open approach from the start. There were no conversions in the group of patients with tumors Ͼ8cm. Operative time for laparoscopic adrenalectomies ranged from 65 minutes to 240 minutes. In the large adrenal tumor group, operative time for laparoscopic resection ranged from 150 minutes to 240 minutes. The postoperative hospital stay for laparo-scopic adrenalectomy ranged from 1 day to 2 days (mean, 1.5) and from 5 days to 20 days for patients undergoing the open or converted procedure. The mean postoperative stay was 2 days for the group with large tumors resected by laparoscopy. Conclusion: Laparoscopic resection of large (Ն8cm) adrenal tumors is feasible and safe. Short-and long-term results did not differ in the 2 groups.

Laparoscopic surgery in functional and nonfunctional adrenal tumors: A single-center experience

2016

BACKGROUND Laparoscopic adrenalectomy (LA) is a safe and minimally invasive operation for benign adrenal tumours. The purpose of this study was a retrospective analysis of outcomes following laparoscopic lateral transabdominal adrenalectomy performed for benign adrenal tumours responsible for various endocrinological disorders and non-functioning tumours. METHODS A total of 100 laparoscopic adrenalectomy were carried out between January 2007 and March 2013 via the lateral transabdominal approach. The analysed factors included demographic data of patients, indication for surgery, tumour size and side, intraoperative and postoperative outcome of laparoscopic lateral transabdominal adrenalectomy including duration of surgery, length of hospital stay, the complication rate, as well as the conversion rate to open adrenalectomy. RESULTS There were 34 patients with non-functioning tumours (Group 1) and 66 with functioning tumours (Group 2). The intraoperative and postoperative outcomes wer...

Feasibility and safety of laparoscopic adrenalectomy for large tumours

Arab journal of urology, 2016

To verify the feasibility and safety of laparoscopic adrenalectomy for large tumours, as since it was described, the laparoscopic approach for adrenalectomy has become the 'gold standard' for small tumours and for large and non-malignant adrenal tumours many studies have reported acceptable results. Patients and methods: This is a retrospective study from a general surgery department from January 2006 to December 2013 including 45 patients (56 laparoscopic adrenalectomies). We divided patients into two groups according to tumour size: <5 or P5 cm, we compared demographic data and peri-and postoperative outcomes. Results: There was no statistical difference between the two groups for conversion rate (3.7% vs 11.7% P = 0.32), postoperative complications (14% vs 12%, P = 0.4), postoperative length of hospital stay (5 vs 6 days P = 0.43) or mortality
