Practical considerations of the gastrostomy button.

Area of Science:

• Gastroenterology
• Medical Devices
• Surgical Procedures

Background:

• Low-profile gastrostomy replacement devices (LPGRDs), or gastrostomy buttons, are a preferred alternative to traditional indwelling catheters for enteral feeding.
• LPGRDs offer improved patient comfort and aesthetics compared to traditional devices.

Observation:

• Contraindications for LPGRD use include specific anatomical factors like acutely angled or long gastrostomy tracts, mucosa-lined tracts, and the need for jejunal feeding or significant decompression.
• Patient-specific factors and gastrostomy tract characteristics influence the scheduling and management of LPGRDs.

Findings:

• Adaptations in management are crucial for maintaining the patency of LPGRDs and ensuring the proper functioning of the anti-reflux valve and plug.
• Special considerations and modifications are required for patients with thickened feedings, medications, intermittent decompression needs, or high intra-abdominal pressure.

Implications:

• Accurate determination of LPGRD size, along with tract dilation or cauterization, are essential steps in the successful application of these devices.
• This discussion provides practical management strategies and a checklist to guide clinicians in the appropriate use and care of LPGRDs.
