This document summarizes the results of 132 parathyroid surgeries performed by Dr. George Ferzli between January 2000 and April 2007. It provides details on patient demographics, pre-operative and post-operative calcium and PTH levels, surgical findings including gland location, weight and size, complications, and outcomes. The mean hospital stay was 1.1 days, incision length was 2.28 cm, and the majority of glands removed were hyperplastic or adenomas, with low rates of hypocalcemia or nerve injury complications.
