Gastrostomy Tube (G-Tube)

Step-by-step guidance on how to perform Gastrostomy Tube. Review tools, techniques, pearls, and pitfalls on the BackTable Web App.

Pre-Procedure Prep

Indications

• Enteral feeding for long-term nutritional support
• Gastric decompression

Many more specific indications that fall into the above categories such as:
• Impaired swallowing
• Stroke
• Aspiration
• Esophageal obstruction

Contraindications

• Lack of safe access to the stomach; large hiatal hernia or prior surgery
• Uncorrectable coagulopathy
• Peritonitis
• Bowel ischemia
• Gastric varices
• Gastric cancer or peritoneal carcinomatosis
• Severe gastroesophageal reflux
• Ascites

Contraindications

• Lack of safe access to the stomach; large hiatal hernia or prior surgery
• Uncorrectable coagulopathy
• Peritonitis
• Bowel ischemia
• Gastric varices
• Gastric cancer or peritoneal carcinomatosis
• Severe gastroesophageal reflux
• Ascites

Pre-Procedural Evaluation

• H&P
• Prior surgery or radiation to stomach or abdomen
• Labs: coagulation profile and CBC
• Prior Imaging - cross sectional of the abdomen
• Provide contrast to patient for oral intake day before procedure to opacify the colon

Procedure Steps

Antibiotics

Push technique:
• 1-2 g cefazolin (Ancef) IV preprocedure
• Clindamycin if PCN allergy
Pull type:
• 1-2 g cefazolin (Ancef) IV preprocedure
• 500 mg cephalexin (Keflex) PO BID x 5 days following procedure
• Clindamycin for PCN allergy

Procedure

Many techniques for placing gastrostomy tube. Push method described below

Prep

• Work from patient's left and have US prepped for liver marking
• Place nasogastric tube if not already done
• 0.5-1.0 g of glucagon to reduce gastric motility and emptying
• Insufflate stomach with air
• Mark liver edge with US

Place T-fasteners

• Optimal G-tube placement is equal distance between greater and lesser curvature at mid to distal body of stomach
• Connect T-fasteners to connection tube with half-filled contrast syringe
• Choose entry site in AP projection and seat needle in soft tissue
• Advance T-fasteners with image intensifier in RAO position: keeps hands out of field and easier to visualize needle indenting the gastric wall
• Aspirate air, then injection contrast to identify gastric folds
• Place 1-3 T-fasteners

Gastrostomy Tube

• Advance 18 g needle into stomach
• Some angle toward antrum anticipating subsequent GJ conversion
• Place 0.035" wire - Amplatz Super Stiff (Boston Scientific)
• Serially dilate
• Advance sheath. Some telescoping sheaths are able to dilate and peel-away
• Place G-tube
• Inflate balloon with sterile water (reasonable to add contrast to solution for better visualization of balloon)
• Inject contrast to outline gastric folds and confirm intragastric position
• Pull balloon to anterior wall and secure disc

Post-Procedure

Post-Procedural Care

• Patient fasting x 12 hours
• Assessed the following day for peritoneal signs
• Instill 30-60 cc of saline through G-tube into stomach: check for resistance with injection or signs of discomfort
• G-tube is then cleared for enteral feeding

Complications

Minor:
• Tube occlusion: 4.5%
• Tube dislodgement: 1.3 - 4.5%
• Leakage around tube: 11%
• Superficial stomal infection: 25 - 45%

Major
• Death: 0.3%
• Peritonitis: 1.3%
• Hemorrhage: < 3%
• Severe skin infection: minimal
• Bowel perforation: minimal

Follow-Up

• If gastropexy tacks do not resorb, remove in 2 weeks
• Chage tube Q6 months or as needed
• First exchange should be with fluoroscopy
• Subsequent exchanges can be done without fluoroscopy

Gastrostomy Tube Demos

Balloon Assisted Gastrostomy (BAG)

This video details a medical procedure developed at Vanderbilt University by Peter R. Bream, Jr. This procedure allows a large bore (20 Fr) gastrostomy tube to be placed de novo using ultrasound and fluoroscopic guidance. The novel technique uses a standard high pressure angioplasty balloon.

Radiographically Placed Gastrostomy Feeding Tubes

This demo shows how to Radiographically place Gastrostomy Feeding Tubes.

Gastrostomy Tube (G-Tube) Placement

Dr. Beck presents his technique for safe and efficient Gastrostomy Tube (G-tube) placement. Indications for G-tube placement include enteral feeding for long-term nutritional support, and gastric decompression. Patients requiring G-tube placement oftentimes suffer from impaired swallowing, stroke, aspiration, or esophageal obstruction.
