ABSTRACT:
An adjustable size balloon at the distal end of a feeding tube is used to aid in positioning, along with an endoscope, the tube in the jejunum or small bowel of a patient, without creating an obstruction in the intestines.The balloon is fully inflated when the endoscope that is used to place the tube in the duodenum is withdrawn, and then partially deflated to a size that allows peristaltic action on the balloon to move the tube into the jejunum, after which the balloon is further deflated to avoid creating an obstruction in the intestine.
