Adrenalectomy: anterior or posterior approach?

Area of Science:

• Endocrinology
• Surgical Oncology
• Minimally Invasive Surgery

Background:

• Adrenal gland surgery is common for conditions like adrenal hyperplasia and adenoma.
• Choosing the optimal surgical approach is crucial for patient outcomes.
• Anterior and posterior approaches have distinct advantages and disadvantages.

Purpose of the Study:

• To compare the efficacy and safety of anterior versus posterior surgical approaches for adrenalectomy.
• To evaluate complication rates, blood requirements, and hospital stay for each approach.
• To determine the preferred surgical route for small, benign adrenal cortical lesions.

Main Methods:

• A retrospective analysis of 103 patients undergoing adrenalectomy.
• Patients had either bilateral cortical hyperplasia or unilateral cortical adenoma (<25g).
• Surgical approaches included anterior (64 patients) and posterior lumbar (39 patients).

Main Results:

• Anterior approach: 18% splenic injury rate requiring splenectomy (left-sided).
• Posterior approach: 26% pleural cavity entry rate.
• Posterior approach associated with lower perioperative blood needs, reduced postoperative morbidity, and significantly shorter hospital stays for both unilateral and bilateral adrenalectomy.

Conclusions:

• The posterior lumbar approach is strongly supported for adrenalectomy in small, benign adrenal cortical lesions.
• This approach offers improved patient outcomes, including reduced complications and faster recovery.
• Surgical technique selection significantly impacts the safety and efficiency of adrenal gland surgery.
