Comparative Perioperative and Oncologic Outcomes of Open, Laparoscopic, and Robotic Adrenalectomy: A Single-Surgeon Experience from a Tertiary Cancer Center
In a single-surgeon cohort of 139 patients at a tertiary cancer center, minimally invasive adrenalectomy (laparoscopic or robotic) was the predominant approach associated with favorable perioperative outcomes, while tumor size and malignancy were the primary factors driving the selection of open surgery for larger or invasive lesions.

Imagine your body as a bustling, high-tech city. Deep inside, tucked just above your kidneys, sit two tiny, almond-shaped command centers called adrenal glands. These aren't just decorative; they are the city's emergency dispatchers and chemical factories. When you're stressed, they pump out adrenaline to get your heart racing. When you need to balance salt and sugar, they release other vital hormones. But sometimes, these little factories get a glitch. They might grow a lump (a tumor) or start spewing chemicals they shouldn't. When that happens, the only way to fix the city is to carefully remove the faulty gland.
For a long time, removing these glands was like performing open-heart surgery on a house: surgeons had to make a huge incision, move everything aside, and work with their bare hands. It worked, but it was messy and left the "house" (the patient) with a big scar and a long recovery. Then, technology brought in the "minimally invasive" tools: laparoscopy (using long, thin tools with cameras) and robotics (using super-precise, dexterous robot arms). The big question for doctors has been: Is the robot the new gold standard? Does it beat the old-school open method, or is it just a fancy, expensive way to do the same thing? And when is it actually safe to use these tiny tools instead of the big knife?
This paper tells the story of a team at a major cancer hospital in Saudi Arabia who decided to settle this debate by looking at their own work. They gathered the records of 139 patients who had their adrenal glands removed between 2012 and 2026. The cool part? Every single one of these surgeries was performed by just one very experienced surgeon. This is like comparing three different ways to bake a cake, but having the exact same baker use the same oven and the same ingredients every time. This removes the "bad baker" variable, letting them see clearly if the method (open, laparoscopic, or robotic) made the difference.
Here is what they found:
The "Big vs. Small" Rule
The study confirmed that the size and nature of the tumor are the ultimate bosses when deciding which tool to use. Think of it like moving furniture. If you have a tiny chair (a small, benign tumor), you can easily carry it out through a narrow hallway using a dolly (minimally invasive surgery). But if you have a massive, heavy sofa that might be broken or dangerous (a large or cancerous tumor), you need to bring in the big crane and knock down the wall (open surgery).
The data showed that for every extra centimeter a tumor grew, the chances of the surgeon choosing the "tiny tools" dropped by about 31%. If the tumor was cancerous, the odds of using minimally invasive tools dropped by a whopping 87%. In this group of patients, 85.6% got the minimally invasive treatment (either laparoscopic or robotic), while only 14.4% needed the big open surgery. The open approach was almost exclusively reserved for the big, scary, or invasive cases.
The Showdown: Open vs. Laparoscopic vs. Robotic
When the researchers compared the three methods, the results were clear for the patients who could handle the smaller tools:
- Open Surgery: This was the "heavy lifter." It took the longest (about 230 minutes on average), involved the most blood loss (300 ml), and kept patients in the hospital the longest (6 days). It was the necessary choice for the big tumors, but it came with a heavier toll.
- Laparoscopic and Robotic: These were the "speed demons." Both methods were much faster (around 130–150 minutes), caused very little blood loss (about 50 ml), and got patients home in just 2 days.
- The Robot vs. The Human Hand: Interestingly, the paper found that the robotic approach and the standard laparoscopic approach were very similar in terms of safety and recovery. The robot didn't necessarily make the surgery faster or safer than the skilled human hand using standard laparoscopic tools in this specific group. However, the robot did offer some advantages in handling complex cases, though the main takeaway was that both minimally invasive methods were superior to the open method for the right patients.
The "Surprise" Factor: Time Matters
One of the most interesting findings was about who ended up needing extra care in the Intensive Care Unit (ICU) after surgery. You might think that a patient with a high-risk heart condition or a huge blood loss would be the one sent to the ICU. But the study found that the only thing that reliably predicted an unplanned ICU stay was how long the surgery took. If the operation dragged on, the patient was more likely to need that extra monitoring. It suggests that a long, drawn-out procedure is a bigger stressor on the body than the specific type of tool used.
The Bottom Line
The study concludes that for most adrenal tumors, the minimally invasive approach (using cameras and long tools) is the winner. It's faster, safer, and gets people home sooner. The robot is a great tool, but it's not a magic wand that fixes everything; it's just another way to do the minimally invasive work. The "old school" open surgery isn't obsolete, though. It remains the essential, heavy-duty option for the largest and most dangerous tumors where safety is the only priority.
In short, the surgeon's choice isn't random. It's a strategic decision based on the tumor's size and behavior. If the tumor is small and friendly, send in the spies (minimally invasive). If it's big and dangerous, bring in the heavy machinery (open surgery). And no matter which tool is used, the goal is the same: get the problem out with the least amount of trouble for the patient.
