Abstract Background Laparoscopic transperitoneal and retroperitoneoscopic adrenalectomy have largely replaced open adrenal surgery, particularly in benign disease. Laparoscopic surgery results in less post-operative pain, fewer surgical site complications and reduced length of hospital stay. The aim of this retrospective study was to analyse the characteristics of patients and evolution of surgical technique in adrenal surgery at Cork University Hospital over a 12-year period. Methods All cases of adrenalectomy between January 1st, 2007 and December 31st, 2018 were retrospectively reviewed. Patient demographics, diagnosis, surgical approach, length of hospital stay, histology and complications were evaluated. Comparisons were made between open, laparoscopic transperitoneal and retroperitoneoscopic adrenalectomy cases. Results There were 57 adrenalectomies performed on 55 patients over the 12-year period. Twenty-six patients (46%) were male, and the mean age was 49 years (range 14–84 years). Twenty-two (39%) right-sided adrenalectomies were performed, 33 (57%) left sided and 2 (4%) patients underwent bilateral surgery. Seventeen adrenalectomies were performed using an open transperitoneal approach, 30 via a laparoscopic transperitoneal approach and 10 using the retroperitoneoscopic technique. Adenoma and pheochromocytoma were the most common indications for surgery (42% and 40%, respectively). Seven percent were performed for malignancy and 5% for other benign indications. The complication rate for open adrenalectomy was 18% versus 10% in laparoscopic transperitoneal adrenalectomy and 0% for retroperitoneoscopic adrenalectomy. Two patients (7%) undergoing laparoscopic transperitoneal surgery required conversion to an open procedure. There were no 30-day mortalities and no disease recurrence within the study time frame. The mean length of hospital stay was 7.6 days in the open group, 5.8 days for the laparoscopic transperitoneal group and 3 days for the retroperitoneoscopic group (p = 0.03). Conclusions Adrenalectomy is a safe procedure and in our setting was primarily performed for pheochromocytoma and nonfunctioning adenomas. Minimally invasive adrenalectomy has become the standard of care internationally and is associated with fewer complications, shorter hospital stay and a low conversion rate.

Introduction The anatomical location of the adrenal glands within the perirenal compartment of the retroperitoneum allows surgery to be performed via a transperitoneal or retroperitoneal approach. Laparoscopic and retroperitoneoscopic techniques have largely replaced open surgery in the surgical management of benign disease [1, 2]. International discordance
