Currently, laparoscopic adrenalectomy (LA) has become the standard treatment for all small adrenal tumors since first being introduced in 1992 by Gagner et al. LA’s superiority has resulted in decreased length of hospital stay, less postoperative pain, decreased length of hospital stay, and finer cosmetic results compared to open adrenalectomy.
The role of LA for a large adrenal tumor is still a debatable issue. There are two major problems of concern. The first is the technical difficulties in removal of a large adrenal tumor can prolong the operative time, increase the blood loss, and lead to perioperative complications. The second is that the risk of malignancy is directed related to the size of the tumor.
Even though there is no clear definition of the size of a large adrenal tumor, the European Society of Endocrinology Clinical Practice Guideline suggested two different approaches. Laparoscopic surgery is recommended for adrenal tumors size < 6 cm which is no local invasion. An individualized surgical approach is recommended for every adrenal tumor size > 6 cm.
This study aimed to evaluate the safety and practicability of LA in patient with a large adrenal tumor by comparing the perioperative outcomes of LA between patients with small (< 6 cm) and large (≥ 6 cm) in our hospital.
