Double-ligament fixation combined with left liver lobe suspension for exposure enhancement in laparoscopic resection of upper gastric cancer and adenocarcinoma of the esophagogastric junction: a technical note
This technical note demonstrates that double-ligament fixation combined with left liver lobe suspension is a safe and effective technique for enhancing exposure during laparoscopic resection of upper gastric and esophagogastric junction cancers, though it should be avoided in patients with Child-Pugh B or C cirrhosis due to observed liver enzyme elevations.

Imagine you are trying to fix a delicate watch, but a giant, heavy, and very wobbly book is constantly sliding over your workbench, blocking your view. In the world of surgery, specifically when operating on the upper part of the stomach or where the stomach meets the esophagus, the liver is that giant book. It sits right on top of the surgical site, and because it is soft and heavy, it tends to flop back down, hiding the area the surgeon needs to see. To fix this, surgeons need a way to hold the liver up and out of the way without hurting it. This is called "liver retraction."
For years, surgeons have used different tools to hold the liver up, like mechanical arms or special silicone discs. However, these tools can sometimes be clunky, require extra cuts in the skin, or just not hold the liver steady enough. If the liver slips even a little, the surgeon might accidentally tear a stitch or miss a tiny lymph node, which could lead to serious problems later. The goal is to find a method that is like a perfect, invisible hand: strong enough to hold the liver up firmly, gentle enough not to bruise it, and quick to set up so the surgery can start sooner. This paper explores a new, clever way to do exactly that.
The "Double-Lock" Solution: A New Way to Hold Up the Liver
In this study, a team of surgeons from Wenzhou Medical University tried out a new trick to solve the "wobbly liver" problem during laparoscopic (keyhole) surgery for stomach and esophageal cancers. They call their method "double-ligament fixation combined with left liver lobe suspension." That sounds complicated, but think of it as a clever two-step game of "tether and tie" to keep the liver out of the way.
The Setup: The Two-Point Anchor
Imagine the liver as a heavy curtain that keeps falling over your face. The surgeons wanted to pull it back and pin it in place using the body's own "ropes" (ligaments).
- The First Pin: They carefully cut a tiny bit of the "curtain rod" (the left triangular ligament) and the "ceiling hook" (part of the coronary ligament). Then, they used a special plastic clip (called a Hemolock) to pin that curtain rod to a nearby sturdy strap (the falciform ligament) that runs down the middle of the belly. This acts like the first anchor point.
- The Second Tie: Next, they took a long thread, passed it through the belly button area, and tied a loop around the "round ligament" (another rope-like structure in the liver). They pulled this thread tight and clipped it to the front wall of the abdomen.
By using these two points together, they created a stable "hammock" that held the left side of the liver up against the front of the belly wall. This freed up the surgeon's hands and the assistant's hands, meaning no one had to spend the whole surgery holding a heavy retractor tool.
The Test Drive
The team tested this new method on 13 patients who needed surgery for upper stomach cancer or cancer at the junction of the esophagus and stomach.
- Did it work? Yes, it worked perfectly in 100% of the cases. The liver stayed put the entire time, and no one had to switch to open surgery or use extra tools to hold the liver.
- How fast was it? Setting up this "double-lock" system took an average of 6.3 ± 1.5 minutes. That's less time than it takes to brew a strong cup of coffee.
- Was it safe? For the most part, yes. No one had a cut or tear in the liver itself. However, two patients (about 15.4%) had a tiny bit of bleeding at the spot where the thread went through the skin, but it stopped quickly with a simple electric cautery tool and didn't require a blood transfusion.
The "Liver Stress" Check
The surgeons were worried that pulling on the liver might stress it out, so they checked the patients' liver enzymes (specifically ALT) before and after the surgery.
- The Result: On the first day after surgery, the liver enzyme levels went up significantly (the median went from 15.6 U/L to 38.3 U/L). This suggests the liver was a little stressed by the pulling.
- The Recovery: By day 3, the levels started dropping, and by day 7, they were back down to 23.5 U/L. While they were still slightly higher than the starting point, the liver was healing up nicely.
- The Warning: The study found something important about patients with existing liver disease. Among the three patients who had cirrhosis (scarring of the liver), the one with the more severe type (Child-Pugh class B with high blood pressure in the liver veins) took longer to recover. The enzyme levels stayed high for longer. This suggests that while the method is great for healthy livers, it might be too much stress for livers that are already weak or scarred.
The Bottom Line
This new "double-ligament" technique is like a clever, low-cost, and fast way to hold the liver up without needing expensive mechanical arms. It gives the surgeon a clear, steady view of the work area and frees up the assistant to help with other tasks. The study suggests it is a safe and effective tool for most patients, but it comes with a caution label: surgeons should be very careful or avoid using it on patients with severe liver scarring or high blood pressure in the liver, as their livers might not bounce back as quickly.
In short, the surgeons found a way to turn the "wobbly book" into a "steady shelf," making the delicate job of removing stomach cancer a little safer and a lot easier to see.
