Abstract

BACKGROUND: Pheochromocytoma (PCC) is a tumor from the chromaffin tissue of the adrenal medulla, capable of hyperproduction of catecholamines. An important feature of pheochromocytoma, due to its hormonal activity, is the threat of sudden changes in hemodynamic parameters during surgical treatment. Retroperitoneoscopic access is currently becoming increasingly popular in the surgical treatment of chromaffin tumors of the adrenal glands. In clinical practice, two variants of the mentioned access are used: classic (three-port) and single-port. In this study, the influence of these options of retroperitoneoscopic access on intraoperative hemodynamic control was evaluated.

AIM: Comparison of treatment results and intraoperative hemodynamic parameters of patients with adrenal pheochromocytomas operated with single-port and three-port retroperitonescopic access options.

MATERIALS AND METHODS: A retrospective single-center cohort study was conducted on a sample of patients initially operated for pheochromocytoma at the Pirogov St. Petersburg State University High Medical Technology Clinic from October 2015 to February 2020 with intraoperative invasive hemodynamic control using PiCCO+ systems.

RESULTS: 47 patients were examined, 24 of whom underwent single–port adrenalectomy (included in the first group), 23 — three-port (second group). The average tumor size in the second group was larger (40.12±9.3 and 56.7±21.5, p<0.05), presumably, in this regard, the average duration of surgery was statistically significantly higher (73±21.5 and 111.7±36.1, p<0.05). The body mass index (BMI) of patients in the two groups did not differ statistically significantly. Intraoperatively measured values of maximum and minimum mean systolic and diastolic blood pressure, the number of episodes of increased diastolic blood pressure above 120 mmHg and their duration did not differ statistically in both groups (p>0.05). Episodes of increased systolic blood pressure above 180 mm Hg were more frequent in the second group (p=0.03), but their total duration in the two groups was without significant differences (p>0.05). Intraoperative consumption of antihypertensive drugs during the release of the adrenal gland and vasopressor drugs after compression of the central vein of the adrenal gland were similar. Blood pressure after compression of the central vein in the first and second groups did not differ significantly (p>0.05). No deaths and postoperative complications were registered in both groups.

CONCLUSION: Single-port modification of retroperitoneoscopic access with sufficient experience of the anesthesiological team and the operating surgeon does not lead to deterioration of hemodynamic control and operation results, being safe and effective in the surgical treatment of pheochromocytoma.
