Summary

This study compared Bard and Mic-key gastrostomy buttons, finding Bard buttons lasted longer but had more valve issues. Mic-key buttons failed more often due to balloon rupture.

Area of Science:

  • Pediatric surgery
  • Gastroenterology
  • Medical device engineering

Background:

  • Gastrostomy buttons are crucial for enteral feeding in children.
  • Advancements have led to different designs, including mushroom-tip (Bard) and balloon-stabilized (Mic-key) buttons.

Purpose of the Study:

  • To compare the longevity and failure modes of Bard and Mic-key gastrostomy buttons.
  • To evaluate the performance characteristics of two common gastrostomy button types.

Main Methods:

  • Retrospective analysis of gastrostomy button insertions at a single institution (Royal Children's Hospital, Brisbane) from 1988 to 1995.
  • Comparison of average button longevity and reasons for removal between Bard and Mic-key devices.

Main Results:

Related Experiment Videos

  • Bard buttons demonstrated a longer average longevity (378.82 days) compared to Mic-key buttons (259.62 days).
  • Valve incompetence was the primary reason for Bard button removal (38%), while balloon rupture was the main cause for Mic-key button removal (44%).

Conclusions:

  • Both Bard and Mic-key gastrostomy buttons have distinct advantages and disadvantages.
  • The choice of gastrostomy button may depend on patient-specific factors and the desired balance between longevity and failure mode profile.
