In percutaneous endoscopic gastrostomy (PEG), which of the following is not used?
## **Core Concept**

The procedure often utilizes a guidewire (like a Savary wire) and a dilator to help place the tube through the abdominal wall and into the stomach.
## **Why Each Wrong Option is Incorrect**
- **Option A:** This option might include commonly used materials or tools in PEG placement, such as guidewires or dilators, making it an incorrect choice as these are indeed used.
- **Option B:** Similarly, this could represent another tool or material integral to the PEG procedure, such as the endoscope itself, which is essential for guiding the tube into place.
- **Option C:** This might represent a type of material or tool occasionally referenced in the context of PEG tubes or their placement, making it incorrect if it's indeed utilized.
## **Clinical Pearl / High-Yield Fact**
A key point to remember is that the success of PEG tube placement and minimizing complications depend on proper technique, patient selection, and post-procedure care. A notable complication to be aware of is the risk of aspiration during the procedure, which can be mitigated by elevating the head of the bed and using prophylactic measures.
