Buote et al: 3D printed cannulas for use in laparoscopic surgery in feline patients: A cadaveric study and case series
Veterinary Surgery 6, 2023

🔍 Key Findings

  • 3D-printed cannulas (3DPCs) reduced mean surgical time significantly in cadaveric procedures (125.6 vs 95.2 min, p = 0.03).
  • Cannula pullout events decreased from a mean of 10 to 2.2 per procedure when using only 3DPCs (p = 0.03).
  • Instrument collisions were significantly fewer with 3DPCs (6.8 vs 2.6 collisions, p = 0.03).
  • Live patients experienced no postoperative complications, including no incision site infections or discomfort.
  • Initial versions of 3DPCs had minor issues, including valve leakage and looser trocar fit, requiring surgical workarounds.
  • Customization of cannula shaft length (3 cm vs standard 5–8.3 cm) improved working space and reduced instrument interference.
  • Production cost was under $5 per cannula, suggesting 3DPCs may be a cost-effective and reusable alternative for small patients.
  • Study supports broader use of 3DPCs in laparoscopic procedures requiring long-jawed instruments or intricate tissue handling.

Multiple Choice Questions on this study

In Buote 2023 et al., on 3D-printed cannulas in feline laparoscopy, which of the following is true about instrument collisions using 3DPCs in cadaver procedures?

A. They were unchanged
B. They increased slightly
C. They occurred only with 11 mm ports
D. They decreased significantly
E. They were only noted in live cases

Answer: They decreased significantly

Explanation: Instrument collisions dropped from 6.8 to 2.6 per procedure when using 3DPCs.
