In simple words: The physician uses a thin, flexible tube with a camera to examine the inside of your upper digestive system, up to a specific part of your small intestine. During the same procedure, the physician changes your feeding tube from your stomach to a different part of your small intestine.

This procedure involves examining the upper digestive tract, from the esophagus through the jejunum, using an endoscope. The existing percutaneous gastrostomy tube is then converted to a percutaneous jejunostomy tube.The ileum is not examined during this procedure.

Example 1: A patient with a percutaneous gastrostomy tube requires conversion to a percutaneous jejunostomy tube due to delayed gastric emptying and needs an evaluation of the small intestine., A patient with a percutaneous gastrostomy tube experiences complications and requires a jejunostomy tube. The physician performs an enteroscopy to evaluate the jejunum and ensure its suitability for the new tube placement., Following a surgical procedure, a patient with a gastrostomy tube develops intolerance to gastric feedings.The physician decides to convert the gastrostomy tube to a jejunostomy tube and performs an enteroscopy to assess the jejunum.

Documentation should include the reason for the procedure, the extent of the endoscopic examination (including the most distal portion of the small intestine reached), the technique used for converting the gastrostomy tube, and any findings or complications.
