Can Risk Scoring Systems Guide the Selection of Laparoscopic Repair in Emergency Perforated Peptic Ulcer? A Retrospective Cohort Study

The Great Ulcer Showdown: When to Go Small and When to Go Big

Imagine your stomach is a bustling city, and sometimes, a tiny wall in that city gets a hole in it. This is called a perforated peptic ulcer. It's a medical emergency where stomach acid and food start leaking into the belly, causing a massive, painful infection. It's like a burst pipe flooding a basement; if you don't fix it fast, the whole house (or in this case, the patient) is in serious trouble. For decades, the only way to fix this was to make a big, open cut in the belly, like tearing open a heavy-duty suitcase to get to the broken zipper. This is "open surgery." But in recent years, surgeons have started using "laparoscopic" surgery, which is like using a tiny, high-tech camera and long, thin tools to fix the hole through just a few tiny keyholes. It's less painful and helps people recover faster, but it's also trickier to do, especially if the patient is already very sick.

The big question doctors have been asking is: "Who should get the tiny keyhole fix, and who needs the big suitcase tear?" Some doctors think the keyhole method is just better for everyone. Others think it's only safe for young, healthy people, and that trying it on sick patients is too risky. To figure this out, they've been using "risk scores"—basically checklists that look at things like age, how sick the patient is, and how long they've been in pain—to predict who will survive. They also look at blood tests that act like smoke detectors for inflammation. The goal is to use these scores to decide the best repair method for every single person, rather than just guessing.

The Study: Checking the Scorecards

In this study, researchers at a large hospital in Turkey looked back at 525 patients who had emergency surgery for a perforated ulcer between 2015 and 2025. They wanted to see if the "risk scores" and blood tests could actually tell them which patients would do better with the tiny keyhole (laparoscopic) repair versus the big open cut. They split the patients into two groups: those who got the laparoscopic repair (189 people) and those who got the open repair (336 people).

At first glance, the results looked like a huge victory for the tiny keyhole method. The patients who got laparoscopic surgery had way fewer serious complications (only 6.3% compared to 22.3% for the open group), died much less often (2.6% vs. 14.6%), and spent less time in the hospital. It looked like the keyhole method was the clear winner.

However, when the researchers looked closer, they found a sneaky trick called "selection bias." It turned out that the surgeons had already been picking the "easy" patients for the keyhole surgery. The laparoscopic group was much younger (average age 39.3 years) and generally healthier than the open surgery group (average age 49.8 years). The sick, older, and more complicated patients were almost always sent straight to the big open surgery.

When the researchers used math to adjust for these differences—essentially asking, "If these two groups were exactly the same age and health, would the surgery type still matter?"—the magic of the keyhole surgery disappeared. The advantage wasn't because the keyhole method was better; it was because the patients chosen for it were already in better shape. The study found that the type of surgery didn't independently change the outcome once you accounted for how sick the patient was to begin with.

The Scorecards Didn't Help

The researchers then tested their main idea: Could the risk scores (like the Boey score, PULP score, and ASA grade) or the blood tests (like NLR, SII, and PNI) act as a guide? Could they say, "If your score is low, do the keyhole; if it's high, do the big cut"?

The answer was a firm no. None of the scores or blood tests showed a significant interaction with the surgery type. In other words, the scores were good at predicting who would get sick or die, but they were terrible at telling the surgeon which tool to use. Whether a patient had a low risk score or a high one, the scores didn't reliably predict that one surgery method would work better than the other for that specific person.

There were some hints in the data. For example, in the group of patients who were already low-risk (young and healthy), the keyhole surgery seemed to have an even bigger advantage. But because the main statistical tests didn't confirm this as a rule, the authors say these are just ideas for future research, not a final rulebook.

The Bottom Line

So, what's the takeaway? The study suggests that while laparoscopic repair looks amazing in the raw numbers, that success is mostly because surgeons pick the healthiest patients for it. The risk scores and blood tests the team looked at are great at predicting who is in danger, but they don't help decide whether to use a keyhole or a big cut.

The authors conclude that we still don't have a perfect tool to tell doctors exactly which surgery to choose for every patient. For now, it seems like the keyhole method is a safe and reliable choice for low-risk patients, but for the sickest patients, the outcome is driven more by how severe their illness is and how long they waited for help, rather than the size of the cut the surgeon makes. We still need better, more personalized tools to help make that life-or-death decision in the emergency room.
