[Prognostic factors in patients undergoing percutaneous endoscopic gastrostomy]

Percutaneous endoscopic gastrostomy (PEG) serves as a major artificial hydration/feeding method in the terminal care of elderly patients. We surveyed the state of patients who underwent PEG at our hospital and investigated the clinical characteristics of patients in the long-term survival group, and the short-term survival group.

The subjects were 125 patients who underwent PEG at our hospital between January 2007 and June 2011. Two kinds of examination were performed. In the first examination, subjects were divided into a short-term group of 37 patients who survived <181 days and a long-term group of 88 patients who survived ≥181 days. In the second examination, subjects were divided into 2 purpose-oriented groups: a prolongation of life group of 76 patients and a being able to eat group of 49 patients. We analyzed the clinical records of these patients and conducted a telephone-based survey.

In the short-term group, there were many cases of PEG after hospitalization due to medical diseases such as pneumonia. In the long-term group, many subjects were young, female, suffered from recurrence of cranial nerve disease, or slowly developed dysphagia. The involvement of rehabilitation doctors, the rate of undergoing rehabilitation for dysphagia, and cases who were able to achieve oral ingestion were significantly high. Of 49 patients who underwent PEG with the aim of being able to eat, 24 achieved oral ingestion.

Our findings suggest that involving rehabilitation doctors and undergoing rehabilitation for swallowing effectively promote long-term survival after PEG.
