Hypothesis
Can a western training center effectively teach circumferential en bloc esophageal endoscopic submucosal dissection (ECE-ESD) using an in vivo animal model?
Conclusion
Training in ECE-ESD is feasible in canine models for postgraduate endoscopy fellows.
Supporting Evidence
- All procedures were completed without complications in the last 3 out of 10 animal models.
- The mean duration for the procedures was 192 ± 35 minutes.
- Average size of the retrieved specimens was 16.1 ± 1.19 mm in length and 51 ± 6.99 mm in width.
- Training improved proficiency, as shown by reduced complications in later cases.
Takeaway
Doctors can learn a special technique to remove cancer from the esophagus using dogs to practice on, and they got better at it with more practice.
Methodology
Ten canine models underwent ECE-ESD under general anesthesia, followed by euthanasia and surgical resection for analysis.
Potential Biases
Potential bias due to the small number of trained staff and the specific training background of the endoscopists.
Limitations
The study had a small sample size and high complication rates in initial cases.
Participant Demographics
Canine models of mongrel breed, weighing between 18-20 kilograms.
