Lateral Transperitoneal Versus Posterior Retroperitoneoscopic Adrenalectomy for Adrenal Tumors: A Randomized...

Area of Science:

• Minimally Invasive Surgery
• Surgical Oncology
• Endocrinology

Background:

• Adrenal tumors necessitate effective surgical interventions.
• Comparing lateral transperitoneal adrenalectomy (LTA) and posterior retroperitoneoscopic adrenalectomy (PRA) is crucial for optimizing patient outcomes.
• Understanding the nuances of different surgical approaches is key in adrenal tumor management.

Purpose of the Study:

• To compare the clinical efficacy of LTA versus PRA for adrenal tumors.
• To identify optimal surgical strategies based on tumor characteristics and surgeon qualifications.
• To evaluate patient outcomes associated with each surgical approach.

Main Methods:

• A prospective randomized controlled trial involving 184 patients with adrenal tumors.
• Random assignment to either LTA or PRA group.
• Subgroup analyses based on tumor diameter, location, and pathology; assessment of surgeon qualification impact.

Main Results:

• PRA showed benefits in fewer trocars, lower complication rates, faster gastrointestinal recovery, and shorter drainage time compared to LTA.
• LTA was superior for tumors >3 cm regarding blood loss and intraoperative complications.
• LTA had higher complication rates for right adrenal tumors, while PRA's outcomes were influenced by surgeon experience.

Conclusions:

• Both LTA and PRA are safe for adrenal tumors, with PRA generally preferred, especially for right-sided tumors.
• LTA may be a suitable option for larger tumors (>3 cm).
• Surgical approach selection should integrate surgeon skill, patient specifics, and tumor attributes.
