Adrenal-sparing surgery: current concepts on a theme from the past.

Area of Science:

• Endocrinology
• Surgical Oncology
• Minimally Invasive Surgery

Background:

• Adrenal insufficiency, often requiring lifelong steroid replacement, leads to significant morbidity.
• Partial adrenalectomy is an evolving surgical approach to preserve healthy adrenal tissue and mitigate replacement-related complications.

Purpose of the Study:

• To review the current indications, techniques, and controversial aspects of partial adrenalectomy.
• To define the role of adrenal-sparing surgery in managing endocrine diseases and adrenal masses.

Main Methods:

• Review of current literature on partial adrenalectomy techniques, including minimally invasive approaches (laparoscopic, retroperitoneoscopic, robot-assisted).
• Discussion of indications such as hereditary pheochromocytoma, Conn's syndrome, Cushing's syndrome, and non-functional adrenal masses.
• Analysis of technical controversies including residual tissue volume, adrenal vein ligation, and tumor identification.

Main Results:

• Partial adrenalectomy is facilitated by advanced minimally invasive surgical technologies.
• Current indications for adrenal-sparing surgery are expanding, but specific criteria are debated.
• No single minimally invasive technique is established as the gold standard due to a lack of comparative studies.

Conclusions:

• Partial adrenalectomy offers a promising alternative to complete adrenalectomy for specific conditions.
• Further research, including prospective comparative studies, is needed to optimize techniques and define the gold standard for adrenal-sparing surgery.
• Addressing technical controversies is crucial for establishing the definitive role of partial adrenalectomy in modern endocrine surgery.
