Question

Which of the following is an advantage of posterior retroperitoneoscopy for adrenal tumors?

• A. Avoidance of mobilization of solid organs
• B. Has large working space
• C. It requires less dissection
• D. Suitable in obese individuals

Hint:

Posterior Retroperitoneoscopic Adrenalectomy:
- Advantage: Direct access to the adrenal gland without mobilization of solid organs or bowel.
- Advantage: Avoids entry into the peritoneal cavity and reduces the risk of postoperative ileus and adhesions.
- Disadvantage: Restricted working space compared with the transperitoneal approach.
- Therefore, for this question, Avoidance of mobilization of solid organs is the key advantage.

Answer 1

The Correct Option is A

Concept:
Posterior retroperitoneoscopic adrenalectomy provides direct access to the adrenal gland through the retroperitoneal space without entering the peritoneal cavity. Its major advantage is avoidance of mobilization of intra-abdominal organs.
Explanation:
• In the posterior retroperitoneoscopic approach, the adrenal gland is approached directly through the retroperitoneum. Therefore, there is no need to mobilize solid organs such as the liver, spleen, or pancreas.

• The approach also avoids manipulation of the bowel and entry into the peritoneal cavity, thereby reducing the risk of postoperative ileus and intra-abdominal adhesions. Hence, Option (A) is the correct answer.

• A major limitation of posterior retroperitoneoscopy is the restricted working space. Therefore, the statement that it has a large working space in Option (B) is incorrect. A relatively larger working space is an advantage of the transperitoneal approach.

• Although the posterior approach provides direct access to the adrenal gland, it does not necessarily require less dissection in every case. The principal advantage emphasized for this approach is avoidance of mobilization of the surrounding intra-abdominal organs. Hence, Option (C) is not the best answer.

• Obesity can make creation and maintenance of the retroperitoneal working space technically more difficult. Therefore, the approach is not specifically considered advantageous in obese individuals. Hence, Option (D) is incorrect.
Final Answer:
The correct answer is (A) Avoidance of mobilization of solid organs. Posterior retroperitoneoscopy allows direct access to the adrenal gland while avoiding entry into the peritoneal cavity and mobilization of major intra-abdominal organs.
