Subtotal adrenalectomy by the posterior retroperitoneoscopic approach

Area of Science:

• Endocrinology
• Surgical Oncology
• Minimally Invasive Surgery

Background:

• The retroperitoneoscopic approach is established for adrenal gland tumors.
• This technique provides clear visualization, enabling differentiation between normal and neoplastic adrenal tissue.
• Subtotal resection of the adrenal gland is sometimes feasible.

Purpose of the Study:

• To evaluate the safety and efficacy of the posterior retroperitoneoscopic approach for subtotal resection of primary benign adrenal gland tumors.
• To assess the potential for preserving adrenal gland cortical function following subtotal resection.

Main Methods:

• Between July 1994 and August 1997, 22 patients underwent posterior retroperitoneoscopic subtotal adrenal gland resection for primary benign tumors.
• Tumor types included Conn adenomas, pheochromocytomas, Cushing adenomas, and hormonally inactive tumors.
• Adrenal gland cortical function was monitored post-operatively.

Main Results:

• Operating time and blood loss for subtotal resection did not differ significantly from complete adrenalectomy.
• All patients with Conn adenomas and pheochromocytomas were cured.
• Adrenal gland cortical function was maintained in most patients, with some requiring minimal steroid supplementation.

Conclusions:

• Retroperitoneoscopically performed subtotal adrenal gland resection is a safe and effective procedure for selected cases.
• This approach can potentially preserve adrenal gland cortical function.
• It offers a viable alternative to complete adrenalectomy for benign adrenal tumors.
