Laparoscopic surgery for malignant adrenal tumors

Area of Science:

• Surgical Oncology
• Minimally Invasive Surgery
• Endocrinology

Background:

• Adrenal tumors require careful management, with surgical approach dictated by tumor characteristics.
• Laparoscopic surgery offers potential benefits but carries risks for malignant adrenal lesions.

Purpose of the Study:

• To outline indications and techniques for laparoscopic surgery in malignant adrenal tumors.
• To detail critical surgical considerations for minimizing complications and ensuring oncologic safety.

Main Methods:

• Review of indications for laparoscopic adrenalectomy in potentially malignant tumors.
• Description of transperitoneal and extraperitoneal approaches for primary and metastatic adrenal cancer.
• Emphasis on surgical techniques to prevent tumor cell dissemination.

Main Results:

• Laparoscopic surgery is contraindicated with clear evidence of invasion on preoperative imaging.
• Tumor size (>6 cm) or preoperative suspicion of malignancy necessitates informed consent regarding potential conversion to open surgery.
• En bloc resection, avoiding tumor manipulation, and careful use of energy devices are vital.

Conclusions:

• Laparoscopic adrenalectomy is feasible for select malignant adrenal tumors without invasion.
• Surgeons must be prepared to convert to open surgery if laparoscopic approach becomes challenging or unsafe.
• Meticulous surgical technique is paramount to prevent tumor recurrence and metastasis.
