Summary

Transgressing the bowel during intraperitoneal catheter placement in pigs did not lead to complications. This animal study suggests bowel perforation is not an absolute contraindication for catheter insertion when other options are unavailable.

Area of Science:

  • Gastroenterology
  • Interventional Radiology
  • Surgical Innovation

Background:

  • Percutaneous catheter placement is a common procedure.
  • Intraperitoneal catheter placement often requires careful consideration of adjacent organ structures.
  • Potential complications of bowel transgression during catheter insertion are not well-defined.

Purpose of the Study:

  • To evaluate the complication rate of small or large bowel transgression during intraperitoneal percutaneous catheter placement.
  • To assess the safety of intentionally traversing the intestine for catheter access in an animal model.

Main Methods:

  • Twenty-four 8-F catheters were placed percutaneously through the small and large bowel of 12 pigs.
  • Catheters were either left in situ until autopsy or removed after 5 days.

  • Computed tomography (CT) scans were performed at various time points to monitor for complications.

    • Main Results:

    • No abscesses or peritoneal effusions were observed on CT scans.
    • Transient pneumoperitoneum occurred in four animals but resolved.
    • Autopsy revealed no bowel leakage, peritonitis, or abscesses; adhesions were noted around the catheter tract.
    • No significant clinical or biochemical complications were observed, regardless of catheter dwell time or bowel type transgressed.

    Conclusions:

    • Traversing the intestine during percutaneous intra-abdominal catheter placement did not result in complications in this animal model.
    • Bowel transgression should not be considered an absolute contraindication for catheter placement when alternative approaches are not feasible.
