About

This research is being done to study the safety of an investigational percutaneous endoscopic gastrojejunostomy (PEGJ) tube and whether the addition of a balloon on the end of the J tube prevents it from slipping back into the stomach.

Full description

The word "investigational" means the PEGJ feeding tube used in this study is not approved by the U. S. Food and Drug Administration (FDA) and is still being tested in research studies. Currently commercially available PEGJ tubes are long tubes which are placed into the part of the small intestine that connects to the stomach (duodenum) under endoscopic guidance. The tip of these PEGJ tubes usually have some built-in extra weight (several grams), which theoretically should prevent slippage of the tube back into the stomach. However, these tubes usually cannot be placed very far into the duodenum and the build-in weight is usually not sufficient to keep the tube in place.

The tip of the currently commercially available PEGJ tubes often (usually within 1-2 weeks) migrates back into the stomach and at that point the tube needs to be replaced. The investigational PEGJ feeding tube used in this study is self-propelled and has a balloon on its tip. The tip of this tube is directed endoscopically through the part of the stomach that connects to the duodenum (pylorus), then the balloon is filled with 5 cc of water and the endoscope is removed. The water filled balloon then is carried by the movement of the intestinal muscles through the duodenum into the middle section of the small intestine (jejunum). It is hoped that such a deep position of the tip of the self-propelled PEGJ tube and presence of the water-filled balloon on its tip will prevent migration of the tube back into the stomach and therefore eliminates the need for tube replacement.

The only difference between the currently approved PEGJ feeding tube and the investigational one being used in this study is the addition of the balloon to the tip of the J port. People who come to Johns Hopkins Hospital for PEGJ placement as part of standard clinical care and who are not pregnant may join the study.
