Balloon-type versus non-balloon-type replacement percutaneous endoscopic gastrostomy: which is better?

Percutaneous endoscopic gastrostomy (PEG) has been an established procedure for nearly 20 years. Caring for patients with a PEG has been incorporated into the practice of nurses in most gastroenterology settings. Several practice-related questions have arisen, particularly in relation to replacement PEGs. In an attempt to obtain relevant information for decisions relating to cost-effectiveness and providing optimum care for PEG replacement, two clinical research questions were studied: (1) is there a difference in patient (stomal) response related to two different replacement PEG tubes, and (2) is there a difference in the duration (life-span) between the two types of replacement tubes? A non-experimental, two-group descriptive study was conducted to answer the two clinical research questions. Two types of replacement PEG tubes were evaluated: a balloon type and a non-balloon type. Stoma response (recording skin and insertion site characteristics) and PEG life span were the measures of interest. Differences in the occurrence of skin and insertion site problems between the two groups were not statistically significant. Differences between the life spans of the two tubes were found to be statistically significant at three time intervals. Findings give information to the practitioner involved in making independent and interdependent practice decisions when planning care for patients with a PEG. Suggestions for additional research and replication are included.
