Posterior Retroperitoneoscopic Adrenalectomy: A Comparison between the Initial Experience in the Invention Phase and Introductory Phase of the New Surgical Technique

摘要

Today, the posterior retroperitoneoscopic technique has become a standard procedure in adrenal surgery. The procedure allows direct access to the adrenal glands, but it seems to be difficult because of the uncommon anatomic view. This study compares the learning period of the new procedure of “posterior retroperitoneoscopic adrenalectomy” in the primary invention phase and the secondary introductory phase in a different hospital 10 years later.
