Senhance-Assisted vs Laparoscopic Pediatric Nissen Fundoplication: A Single-Center Multidisciplinary Comparative Cohort Study from a German Tertiary Center
This single-center comparative cohort study demonstrates that Senhance®-assisted robotic Nissen fundoplication in children is a feasible and safe alternative to conventional laparoscopy, offering comparable surgical and anesthetic outcomes despite longer initial preparation times associated with the learning curve.

Imagine a child's stomach is like a leaky valve that lets acid splash back up into the throat. To fix this, surgeons perform a "Nissen fundoplication," which is essentially wrapping the top of the stomach around the esophagus to create a tighter seal. For years, surgeons have done this using Laparoscopy (LNF), which is like doing delicate surgery through tiny holes using long, straight sticks (instruments) and a camera. It works well, but the sticks can be a bit stiff and hard to maneuver in a small space.
Recently, a new tool called the Senhance® Robotic System (RNF) was introduced. Think of this as upgrading from those stiff sticks to a pair of "robotic hands" that can twist, turn, and feel resistance (haptic feedback), all controlled by a surgeon sitting at a console. However, because this is new technology for children, doctors wanted to know: Is it safe? Does it take too long? Does it hurt the child more?
This study from a German hospital compared two groups of children: 18 who got the new Robotic surgery and 18 who got the traditional Laparoscopic surgery. Here is what they found, explained simply:
1. The "Setup" Takes Longer, But the "Cooking" Time is the Same
Imagine setting up a robotic kitchen versus a standard one.
- Preparation: Getting the robot ready (docking the arms, setting up the camera) took significantly longer for the robotic group (about 105 minutes) compared to the standard group (about 69 minutes). It's like spending extra time calibrating a high-tech drone before you can even fly it.
- The Surgery: Once the robot was ready, the actual time spent fixing the stomach was almost identical for both groups (about 170 minutes). The robot didn't make the surgery itself faster or slower than the traditional method.
- The Learning Curve: The study noticed that as the team did more robotic surgeries, they got faster at setting up the robot. It's like learning to drive a new car; the first few times you fumble with the gears, but soon it becomes second nature.
2. Safety and "Crashes"
- No Disasters: In both groups, no one had to switch to "open surgery" (cutting a large hole in the belly). That's a big win for both methods.
- The "Robot Glitch": In 3 out of the 18 robotic cases, the surgeons had to switch from the robot to the standard laparoscopic tools. Why? Not because the patient was too small or sick, but because of workflow issues—like the robot arm bumping into something or the "force feedback" (the feeling of resistance) getting in the way during a specific step. The authors call this a "safety switch" rather than a failure; the surgeons knew when to bail out and finish the job the old-fashioned way to keep the child safe.
3. The "Passengers" (The Children)
There was a slight difference in who got the robot. The children in the robotic group were generally older and heavier than those in the traditional group.
- Why? The robot has a rule: it can only be used on kids over 1 year old and weighing at least 10 kg (about 22 lbs). Also, since the robot was only introduced in 2022, the older kids happened to be the ones available when the robot arrived.
- Despite these kids being bigger (which usually makes surgery harder), the robot handled them just as well as the traditional method handled the smaller kids.
4. Recovery: The "Hangover" is the Same
After the surgery, the kids were monitored closely for pain, confusion (delirium), and how much they needed for pain relief.
- Pain: Both groups felt about the same amount of pain.
- Medication: Both groups needed similar amounts of painkillers. Interestingly, the robotic group used a tiny bit more of a specific non-opioid painkiller (metamizole), but overall, the need for strong opioids was low and equal in both groups.
- Hospital Stay: Both groups went home in about the same amount of time (3 to 4 days).
- Complications: The rate of problems after surgery (like fever or needing to come back to the hospital) was very low and statistically the same for both groups.
The Bottom Line
The study concludes that using the Senhance® robot for this specific stomach surgery in children is safe and effective.
- It doesn't hurt the child more than the traditional method.
- It doesn't make the recovery harder.
- It doesn't increase the risk for the anesthesiologist.
- The main downside is that it takes a bit longer to get the robot ready at the start of the day.
The authors suggest that while the robot is a great new tool, it requires a "learning phase" where the whole team (surgeons, nurses, anesthesiologists) practices together to get the setup time down. Once the team is trained, the robot is a solid, safe alternative to the traditional method, offering the same results with the added benefit of those flexible "robotic hands."
