Laparoscopic Adrenalectomy in Elderly Patients

Impact of frailty on complications and length of stay after minimally invasive adrenalectomy surgery

BACKGROUND

Adrenal disease requiring surgery incidence increases with age, and minimally invasive adrenalectomy procedures have improved the safety of adrenal surgery. This study evaluates the perioperative outcomes of elective adrenalectomies when performed in older patients and how frailty affects such outcomes.

METHODS

Patients undergoing elective minimally invasive adrenalectomy were identified using the American College of Surgeon's National Surgical Quality Improvement Program Participant Use Targeted File years 2005 to 2020. The surgical indication was categorized as a benign disease, an endocrine disorder, or a malignant disease. Frailty was defined using the 5-item modified frailty index. Multivariable regressions were used to model the relationship of age and frailty with surgical outcomes.

RESULTS

In 8,693 minimally invasive adrenalectomy patients, 5,281 (61%) were female, 5,026 (58%) were White, and 1,924 (22%) were aged 65 years or older. Surgical indications were benign disease 5,487 (63%), endocrinopathy 2,850 (33%), and malignancy 356 (4%). Patients aged <65 years (compared to those aged ≥65) were more likely to have a 5-item modified frailty index = 0 (26% vs 14%, respectively) and less likely to have a 5-item modified frailty index = ≥3 (2% vs 4%, respectively; P < .001).

OUTCOMES

30-day mortality 20 (0.2%), complications 459 (5%), return to operating room 73 (0.8%), and median length of stay 2 days. Thirty-day mortality was associated with a 5-item modified frailty index ≥3 (P = .009) and endocrine disease (P = .005) but not with age. Complications were associated with a 5-item modified frailty index ≥2 (≤P < .001) and malignant disease (P = .002), but not with age.

CONCLUSION

Minimally invasive adrenalectomy has low 30-day mortality and complication rates that increase with frailty and not age. Frailty is a better predictor than the age of most adverse outcomes after elective minimally invasive adrenalectomy.

Is laparoscopic adrenalectomy for pheochromocytoma safe and effective in geriatric patients?

OBJECTIVES

The study aimed to assess the haemodynamic changes of laparoscopic adrenalectomy (LA) in geriatric patients with pheochromocytoma (PHEO). To the best of our knowledge, this is the first study to evaluate the haemodynamic outcomes of LA in this patient population.

METHODS

Data of 350 patients who underwent single-side transperitoneal LA between 2000 and 2020 were reviewed retrospectively. Patients with a histopathological diagnosis of PHEO were included in the study and classified into two groups according to their ages at the date of surgery. Patients older than 65 years were accepted as elderly according to the World Health Organisation (WHO) recommendations.

RESULTS

A total of 54 patients underwent LA for PHEO. Fifteen patients were enrolled in the elderly and 39 in the young groups. There were no significant differences in terms of the operation site (0.564), tumour size (0.878), perioperative results such as mean anaesthesia; operation times, blood loss and haemodynamic changes. There were no significant differences in mean hospitalisation and intensive care unit times. One patient in both groups had grade 1 complication according to Clavien Dindo classification (prolonged ileus, managed with medical treatment and transfusion during surgery, respectively).

CONCLUSION

Young and elderly patients had similar outcomes in terms of haemodynamic changes that occurred with LA. LA in elderly patients with PHEO is as safe and effective as in younger patients.

Adrenal Surgery for Cushing's Syndrome: An Update

Recent advances in the molecular pathogenesis and the natural history of Cushing's syndrome have improved the understanding of the management of this disease. The long-term efficacy of several cortisol-lowering medical treatments is currently under evaluation. However, adrenalectomy is a safe option for the treatment of patients affected by Cushing's syndrome. Unilateral adrenalectomy is the gold standard for treatment of adrenocortical adenomas associated with hypercortisolism. Bilateral adrenalectomy has been widely used in the past as definitive treatment of bilateral macronodular hyperplasia and persistent or recurrent Cushing's disease. The indication and the potential applications of this technique have been recently critically analyzed.
