What is the standard size of the PEG tube used for PEJ placement?

The standard size of the PEG (Percutaneous Endoscopic Gastrostomy) tube used for PEJ (Percutaneous Endoscopic Jejunostomy) placement is typically 16G. The choice of this gauge size is significant because it balances the need for adequate flow and nutrition delivery while minimizing tissue trauma during the insertion process.

A 16G tube is large enough to allow for the passage of various types and viscosities of enteral feedings, medications, and to facilitate venting while remaining small enough to reduce complications. The gauge size also impacts the insertion technique and patient comfort, as larger gauges may lead to more discomfort post-insertion.

In practice, while options of different gauges exist, 16G has become a standard and widely accepted choice in many clinical settings for PEJ placements. Thus, understanding the implications of the gauge size on patient outcomes and procedural efficiency is essential for optimal care.
