Definition

A gastrostomy feeding tube (G-tube) insertion is the placement of a feeding tube through the skin and the stomach wall. It goes directly into the stomach.

Description

Gastrostomy feeding tube insertion is done in part using a procedure called endoscopy. This is a way of looking inside the body using a flexible tube with a small camera on the end of it. The endoscope is inserted through the mouth and down the esophagus, which leads to the stomach.

After the endoscopy tube is inserted into the stomach, the skin over the left side of the belly (abdomen) area is cleaned and numbed. Your surgeon makes a small surgical cut in this area. The G-tube is inserted through this cut into the stomach. The tube is small, flexible, and hollow. Your surgeon uses stitches to close the stomach around the tube.

Why the Procedure Is Performed

Gastrostomy feeding tubes are put in for different reasons. They may be needed for a short time or permanently. This procedure may be used for:

Babies with birth defects of the mouth, esophagus, or stomach (for example, esophageal atresia or tracheal esophageal fistula)
People who cannot swallow correctly
People who cannot take enough food by mouth to stay healthy
People who often breathe in food when eating

Risks

Risks for surgical or endoscopic feeding tube insertion are:

Bleeding
Infection

Before the Procedure

You will be given a sedative and a painkiller. In most cases, these medicines are given through a vein (IV line) in your arm. You should feel no pain and not remember the procedure.

A numbing medicine may be sprayed into your mouth to prevent the urge to cough or gag when the endoscope is inserted. A mouth guard will be inserted to protect your teeth and the endoscope.

Dentures must be removed.

After the Procedure

This is most often a simple surgery with a good outlook. Follow any self-care instructions you're given, including:

How to care for the skin around the tube
Signs and symptoms of infection
What to do if the tube is pulled out
Signs and symptoms of tube blockage
How to empty the stomach through the tube
How and what to feed through the tube
How to hide the tube under clothing
What normal activities can be continued

Outlook (Prognosis)

The stomach and abdomen will heal in 5 to 7 days. Moderate pain can be treated with medicine. Feedings will start slowly with clear liquids, and increase slowly.
