Objectives: To compare the intraoperative and postoperative course of patients undergoing laparoscopic pheochromocytoma resection at 2 institutions (Mayo Clinic and Cleveland Clinic) with differing approaches to preoperative preparation. Patients undergoing adrenalectomy for pheochromocytoma typically undergo a preoperative preparation to normalize their blood pressure and intravascular volume. However, no consensus has been reached regarding the best preoperative preparation regimen. Methods: A retrospective chart review was performed of 50 Mayo Clinic patients and 37 Cleveland Clinic patients who had undergone laparoscopic pheochromocytoma resection. Mayo Clinic predominantly used the long-lasting nonselective α1,2 antagonist phenoxybenzamine, and Cleveland Clinic predominately used selective α1 blockade. Data regarding the intraoperative hemodynamics and postoperative complications were collected. Results: Almost all patients at Mayo Clinic received phenoxybenzamine (98%). At Cleveland Clinic, the predominant treatment (65%) was selective α1 blockade (doxazosin, terazosin, or prazosin). Intraoperatively, patients at Cleveland Clinic had a greater maximal systolic blood pressure (209 ± 44 mm Hg versus 187 ± 30 mm Hg, P = .011) and had received a greater amount of intravenous crystalloid (median 5000, interquartile range 3400-6400, versus median 2977, interquartile range 2000-3139; P <.010) and colloid (median 1000, interquartile range 500-1000, versus median 0, interquartile range 0-0; P <.001). At Mayo Clinic, more patients had received phenylephrine (56.0% versus 27.0%, P = .009). No differences were found in the postoperative surgical outcomes, and the hospital stay was comparable between the 2 groups. Conclusions: Differences in the preoperative preparation and intraoperative management were associated with differences in intraoperative hemodynamics but not with clinically significant outcomes in patients undergoing laparoscopic adrenalectomy for pheochromocytoma at 2 large tertiary care centers.
