Haemodynamic changes during retroperitoneoscopic adrenalectomy for phaeochromocytoma.

Surgical removal of phaeochromocytoma may be accompanied by acute cardiovascular changes. We report the haemodynamic changes in seven patients with retroperitoneal laparoscopic adrenalectomy for phaeochromocytoma. Transient hypertension (systolic pressure (SBP) > 160 mm Hg) was observed in all patients during manipulation of the tumour, in two patients during pneumoretroperitoneum insufflation, and in one patient during intubation. Small doses of nicardipine were sufficient to control these episodes of hypertension. Transient hypotension (SBP < 100 mm Hg) was observed in two patients during exsufflation and in one patient during repositioning to the lateral position. Our observations suggest that this approach provides relative haemodynamic stability, especially during pneumoretroperitoneum insufflation.
