Name of the Procedure:

Contrast injection(s) for radiological evaluation of existing gastrostomy, duodenostomy, jejunostomy, gastro-jejunostomy, or cecostomy (or other colonic) tube from a percutaneous approach, with image documentation and report.

Summary

In this procedure, a contrast dye is injected into an existing feeding or drainage tube to visually assess its position and functionality using radiological imaging. The results are documented and a medical report is generated.

Purpose

This procedure is performed to ensure that the existing feeding or drainage tubes are correctly positioned and functioning as intended. The primary goal is to diagnose any potential issues such as blockages, dislocations, or leaks.

Indications

• Symptoms such as difficulty feeding or drainage issues
• Suspected tube blockage or dislocation
• Unexplained gastrointestinal symptoms in patients with an existing tube
• Routine checks on tube function and positioning

Preparation

• Fasting for a few hours prior to the procedure may be required.
• Adjustments to certain medications might be necessary as directed by the healthcare provider.
• Diagnostic tests like blood tests may be conducted for assessment.

Procedure Description

1. The patient is positioned to allow clear access to the tube.
2. The area around the tube insertion site is cleaned and sterilized.
3. A contrast dye is carefully injected into the tube.
4. Radiological imaging (such as X-rays or fluoroscopy) is performed to visualize the flow of the dye.
5. Multiple images are taken to ensure comprehensive evaluation.
6. The images are reviewed, and a report is generated documenting the findings.

Duration

The procedure typically takes about 30 to 60 minutes.

Setting

The procedure is usually performed in a hospital or an outpatient radiology clinic.

Personnel

• Radiologist (physician specialized in imaging)
• Radiologic technologist or nurse
• Potentially an anesthesiologist if sedation is used

Risks and Complications

• Allergic reaction to the contrast dye (rare)
• Infection at the tube site
• Minor bleeding or irritation
• Discomfort or pain during the dye injection

Benefits

• Accurate assessment of tube positioning and function
• Early detection of problems, allowing for timely intervention
• Minimally invasive with quick recovery

Recovery

• Observation for a short period after the procedure
• Normal activities can usually be resumed almost immediately
• Follow-up appointments as advised by the healthcare provider

Alternatives

• Clinical evaluation and physical exams
• Ultrasound or other imaging methods without contrast
• Endoscopic evaluation, though more invasive

Patient Experience

Patients may feel a brief sting or discomfort during the dye injection. The imaging process is generally painless. Pain management and comfort measures, such as local anesthesia at the injection site, are provided as needed.
