Comparison of Robotic Posterior Retroperitoneal Adrenalectomy over Laparoscopic Posterior Retroperitoneal Adrenalectomy: A Single Tertiary Center Experience

الملخص EN

Background.

The aim of this study is to compare the clinical outcomes of laparoscopic posterior retroperitoneal adrenalectomy (LPRA) and robotic posterior retroperitoneal adrenalectomy (RPRA) and determine the differences that could affect the outcomes.

Methods.

We retrospectively analyzed 230 adrenalectomy cases from 2014 to 2017.

There were 169 LPRA and 61 RPRA cases, and their clinicopathological features and surgical outcomes were compared.

Results.

In LPRA, there was a positive relationship between operation time and male gender, early period of experience, adrenal tumor size, and pheochromocytoma.

In RPRA, adrenal tumor size and pheochromocytoma were the factors affecting the operation time.

When the adrenal tumor size was ≤5.5 cm, the operation time of LPRA was shorter than that of RPRA (p=0.001).

When the tumor size was >5.5 cm, there was no significant difference in the operation times of LPRA and RPRA (p=0.102).

Conclusions.

RPRA is a feasible and technically safe approach for benign adrenal diseases.

The use of RPRA could benefit patients and provide comfort by overcoming the factors contributing to a longer operation time in the laparoscopic technique, such as male gender and high BMI.
