Summary
Endoscopic subtotal adrenalectomy can preserve sufficient adrenal function even when the main adrenal vein is cut or less than one third of the gland remains. Approximately one third of the adrenal gland is sufficient for adequate function.
Area of Science:
- Endocrinology
- Surgical Oncology
- Laparoscopic Surgery
Background:
- Adrenalectomy is a common surgical procedure for adrenal gland pathologies.
- Preserving adrenocortical function post-adrenalectomy is crucial for patient well-being.
- Endoscopic subtotal adrenalectomy aims to balance tumor removal with functional tissue preservation.
Purpose of the Study:
- To determine the minimum amount of residual adrenal tissue required for adequate function after endoscopic subtotal adrenalectomy.
- To assess the necessity of an intact adrenal vein for maintaining sufficient adrenocortical function post-procedure.
Main Methods:
- Endoscopic subtotal adrenalectomy was performed in 14 patients.
- Analysis of postoperative serum cortisol and adrenocorticotropic hormone (ACTH) levels.
- ACTH stimulation tests were conducted in patients with bilateral tumors.
Main Results:
- Sufficient adrenocortical function was confirmed by postoperative ACTH tests.
- The main adrenal vein was ligated in 10 patients.
- As little as one-third of the adrenal gland remaining in situ supported adequate function.
- No tumor recurrence was observed during approximately 24 months of follow-up.
Conclusions:
- Laparoscopic subtotal cortical-sparing adrenalectomy is a viable and successful surgical approach.
- Preservation of the main adrenal vein is not essential for maintaining adequate adrenocortical function.
- Leaving approximately one-third of the adrenal gland is estimated to be sufficient for maintaining hormonal balance.
