Laparoscopic adrenalectomy for adrenal masses: does size matter?

Area of Science:

• Endocrinology
• Surgical Oncology
• Minimally Invasive Surgery

Background:

• Adrenal tumors are common, and surgical management is often necessary.
• Laparoscopic adrenalectomy is the preferred surgical approach.
• The impact of adrenal tumor size on surgical outcomes requires further elucidation.

Purpose of the Study:

• To investigate the relationship between adrenal tumor size and perioperative morbidity.
• To evaluate the effect of adrenal tumor size on postoperative outcomes following laparoscopic adrenalectomy.

Main Methods:

• A prospective study of 227 patients undergoing laparoscopic adrenalectomy.
• Patients were categorized into three groups based on adrenal tumor size: <6 cm, 6-7.9 cm, and ≥8 cm.
• Clinical and pathological data were collected and analyzed.

Main Results:

• Operative time, blood loss, and hospital stay were significantly longer for tumors ≥8 cm compared to those <6 cm.
• Average operative time was 80 minutes for tumors ≥8 cm versus 60 minutes for tumors <6 cm.
• Median blood loss was 100 mL for tumors ≥8 cm versus 50 mL for tumors <6 cm, with a mean hospital stay of 3 days versus 2 days, respectively.

Conclusions:

• Laparoscopic adrenalectomy for large adrenal masses (≥8 cm) is associated with increased operative time, blood loss, and hospital stay.
• Perioperative morbidity was not significantly affected by adrenal tumor size.
• Tumor size is an important factor to consider in planning laparoscopic adrenalectomy.
