A new pull-through trocar technique for percutaneous operative endoscopy.

A pull-through trocar is described which establishes a percutaneous access to the stomach and may immediately be used for endoscopy. The trocar is placed in a similar fashion to PEG probes. The technique was evaluated in animals. Using rigid endoscopes and instruments introduced through the trocar operative manipulations of the gastric wall were carried out. There were no severe complications. The new method extends the scope of percutaneous therapeutic endoscopy (minimal invasive surgery) by permitting direct access to the interior of the stomach.
