Overview

This retrospective observational study examines whether abdominal circumference is associated with operative time in patients undergoing retroperitoneal adrenalectomy for pheochromocytoma. Data were collected from medical records of patients treated at a single tertiary referral center. The primary outcome is operative time, measured in minutes.
