Summary

Fluoroscopic guided percutaneous gastrostomy is effective for enteral feeding, with a high success rate. Early detection of intraperitoneal leakage using chest X-rays aids management.

Area of Science:

  • Medical Imaging
  • Gastroenterology
  • Interventional Radiology

Background:

  • Percutaneous gastrostomy is a common procedure for enteral feeding.
  • Assessing the functional performance and potential complications of gastrostomy tubes is crucial.

Purpose of the Study:

  • To evaluate the functional performance of fluoroscopically guided percutaneous gastrostomy tubes.
  • To assess the utility of radiological investigations in detecting intraperitoneal leakage.
  • To propose a management protocol for suspected leakage.

Main Methods:

  • Retrospective review of 38 patients undergoing fluoroscopically guided percutaneous gastrostomy over 21 months.
  • Analysis of gastrostomy tube function, including instances of malfunction and replacement.

Related Experiment Videos

  • Evaluation of radiological findings, particularly sequential erect chest films, for diagnosing intraperitoneal leakage.

    • Main Results:

    • A functioning gastrostomy tube was established in 34 (89.5%) patients.
    • Average tube function duration was 10.75 weeks, with 34 tubes requiring intervention due to dislodgement, blockage, or leakage.
    • Increasing pneumoperitoneum on sequential postprocedure erect chest films reliably indicated intraperitoneal leakage.

    Conclusions:

    • Fluoroscopically guided percutaneous gastrostomy demonstrates satisfactory overall functional success for enteral feeding.
    • While individual tube function had limitations, the procedure is effective.
    • A protocol for managing suspected intraperitoneal leakage based on chest film findings is proposed.
