Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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. The purpose of this study is to evaluate whether abdominal circumference can serve as a practical predictor of operative difficulty in retroperitoneal adrenalectomy.
