?:definition
  • Gastrostomy tubes designed for stomach decompression and jejunal feeding. They may be placed surgically (e.g., open surgery, laparotomy) or by using a percutaneous endoscopic procedure with minimum sedation in outpatients or at the bedside. These devices typically consist of a dual-lumen plastic (e.g., polyurethane) tube of 12 to 18 French diameter with a balloon at each tip. The tube is inserted and advanced through the pylorus; the balloon is inflated with water and moved through the duodenum into the jejunum. The tip of the second lumen of the tube is positioned in the stomach. Gastrostomy decompression/jejunal feeding tubes are intended to provide jejunal feeding using standard gastrostomy insertion procedures; they are used to feed patients who require long-term enteral feeding but who are unable to maintain sufficient oral intake (e.g., patients who have severe neurologic impairment; they are also used in patients who have tumors of the mouth, larynx, or esophagus) who also require stomach decompression.
