3D-printed endoscopic model boosts trainee comfort with IR procedures

Using a 3D-printed endoscopic training model increased the comfort level of trainees during interventional radiology (IR) procedures, reported authors of an Aug. 29 study in Current Problems in Diagnostic Radiology.

Many patients are burdened with life-long catheters due to medical comorbidities inhibiting surgery, but other options, such as percutaneous endoscopic intervention, could ultimately remedy their situation. The problem is, according to lead author Jacob J. Bundy, MD, and colleagues, few IR specialists perform this technique.

“A simple method to teach physicians the techniques of these procedures is greatly needed to educate and expand the use of this very valuable procedure,” the authors wrote.

Researchers performed a magnetic resonance cholangiopancreatography (MRCP) study on a single patient to create a 3D endoscopic model of the biliary tract.

Eleven trainees completed a 10-question survey before and after a 3D endoscopy simulation, eight of whom had no prior endoscopy training.

Overall, trainees found the 3D model easy to use and reported their ability to use and operate an endoscope improved “significantly,” while their knowledge of the biliary tract improved only slightly, Bundy et al. noted.

The group reported a mean comfort level increase in using endoscopy alone for four IR procedures: cholecystostomy (38.9 percent increase), percutaneous biliary drainage (32.8 percent), percutaneous nephrostomy (32.8), and percutaneous gastrostomy (34.3 percent).

“The use of a 3-D endoscopic model as a simulation tool may improve comfort using endoscopy during interventional radiology procedures and has the potential to serve as an effective teaching platform to improve technical skills,” Bundy and colleagues concluded.
