Endoscopic placement of gastrostomy tubes is used primarily for long-term nutritional support and where naso-oesophageal or oesophagostomy tube feeding is not possible.
Figure G.5:(a) The mushroom tip of the PEG tube is looped through the swaged-on wire loop to join it to the wire loop passing out of the mouth. (b) The wire loops are interlocked. (c) The wires are pulled tight to produce a knotless connection.
Figure G.6:(a) The guidewire is pulled to draw the feeding tube into the mouth, down the oesophagus, into the stomach and (b) out through the stomach wall.
