Risk factors for haemodynamic instability and its prolongation during laparoscopic adrenalectomy for pheochromocytoma.

Abstract

OBJECTIVE:

Pheochromocytoma is a rare neuroendocrine tumour that secretes catecholamines and originates in the adrenal gland. Although surgical resection is the only curative therapy for pheochromocytoma, it is associated with a risk of haemodynamic instability (HDI), such as extremely high blood pressure and/or post tumour removal hypotension and shock. We investigated the risk factors for HDI during pheochromocytoma surgery.

DESIGN AND PATIENTS:

Eighty-two patients who underwent laparoscopic adrenalectomy for pheochromocytoma between July 2002 and February 2020 were examined. We excluded 3 patients with bilateral disease and 11 without detailed 24 h urinary data. We defined HDI as systolic blood pressure ≥ 200 or <80 mmHg. We investigated the risk factors for HDI during laparoscopic adrenalectomy for pheochromocytoma.

RESULTS:

There were 29 males and 39 females with a median age of 50.5 years. Tumours were localised on the right adrenal gland in 28 patients and on the left in 40. The median tumour diameter was 37.5 mm and the median pneumoperitoneum time was 93.5 min. Twenty-five out of sixty-eight patients (37%) developed HDI. A multivariate analysis identified diabetes mellitus (DM; odds ratio: 3.834; 95% confidence interval: 1.062-13.83; p = .04) as an independent predictor of HDI. In terms of hormonal data, median 24 h urinary epinephrine levels (p = .04) and metanephrine levels (p = .01) were significantly higher in the HDI group. DM was also considered as a risk factor for prolonged HDI (p = .02).

CONCLUSION:

Surgeons and anaesthesiologists need to be aware of the risk of HDI and its prolongation during laparoscopic adrenalectomy for pheochromocytoma for DM patients.
