PEG-Related Complications and One-Year Survival in Patients with Neurological Disorders: A Retrospective Cohort Study
This retrospective cohort study of 276 neurological patients found that PEG-related complications occurred in 27.5% of cases, with increasing age being the only independent predictor of complications, while none of the evaluated baseline variables predicted one-year mortality, which was approximately 76.4%.

When a person suffers from a severe neurological condition, such as a stroke, dementia, or a progressive disease affecting the nerves and muscles, the ability to swallow safely can disappear. Without this ability, the body cannot receive the food and water it needs to survive, even though the stomach and intestines remain fully functional. To solve this, doctors often place a small, flexible feeding tube directly through the skin of the abdomen and into the stomach. This procedure, known as a percutaneous endoscopic gastrostomy, creates a permanent doorway for nutrition. While this intervention is a lifeline for many, it is not without risks. The tube can become blocked, slip out of place, or cause irritation and infection at the site where it enters the body. Furthermore, because these patients are often very ill to begin with, their long-term outlook depends heavily on the underlying disease rather than the tube itself. Understanding how often these tubes cause trouble and how long patients typically live after the procedure is essential for families and doctors making difficult care decisions.
Researchers at Mersin City Training and Research Hospital in Turkey set out to examine these realities in a group of 276 adults with neurological disorders who received this feeding tube between 2017 and 2025. They looked back through medical records to track two main things: how often the tubes caused problems and how many patients were still alive one year after the procedure. The team focused on specific, tangible issues like fluid leaking from the tube site, the tube getting clogged, or the tube moving out of its proper position. They also gathered basic health information available at the time the tube was placed, including the patient's age, sex, and levels of two common blood markers: one that signals inflammation and another that reflects nutritional status. By analyzing this data, the researchers aimed to see if any of these starting factors could reliably predict who would face complications or who would pass away within a year.
The study revealed that complications were fairly common. More than one-quarter of the patients, specifically 76 individuals, experienced at least one documented issue with their feeding tube. The most frequent problems involved fluid discharge from the site where the tube entered the skin, followed closely by the tube accidentally slipping out or becoming blocked. Despite these frequent mechanical issues, the overall survival rate was higher than the complication rate might suggest. Approximately three-quarters of the patients were still alive one year after the procedure. This finding highlights a crucial distinction: while the tube itself often requires maintenance or repair, the decision to place it does not necessarily dictate whether a patient survives the year. The underlying neurological condition remains the primary driver of life expectancy.
When the researchers tried to find a pattern in who would get sick from the tube or who would die, the results were surprisingly specific. They found that age played a role in the likelihood of tube complications, but in an unexpected direction. Older patients were actually less likely to have a documented problem with their tube than younger patients. The researchers suggest this might not mean older people are healthier, but rather that younger patients often survive longer with the tube, giving them more time to experience issues like dislodgement or blockage. In contrast, the study found no evidence that the patients' sex, their level of inflammation, or their nutritional blood markers could independently predict whether they would die within a year. Even though patients who passed away tended to have slightly higher inflammation markers and lower nutritional markers when they first received the tube, these numbers did not hold up as reliable predictors once all the factors were considered together.
This work underscores that the outcome for a patient with a neurological disorder receiving a feeding tube is complex and cannot be reduced to a single lab test or a simple demographic fact. The study confirms that while the feeding tube is a vital tool, it brings its own set of mechanical challenges that affect a significant portion of users. At the same time, it shows that the body's ability to survive the year is determined by a broader, more intricate picture of the patient's overall health and disease trajectory than just a few blood tests can reveal. For doctors and families, this means that predicting the future requires looking at the whole person and their specific journey, rather than relying on isolated numbers or assumptions about age and gender. The path forward involves careful, individualized monitoring of the tube itself and the patient's general condition, acknowledging that the device is a support, not a cure, for the underlying illness.
