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.
