Disposable Versus Reusable Gastroscope: A Prospective Randomized Non-Inferiority Trial

While disposable electronic gastroscopes were comparable to reusable gastroscopes for capturing images, the image quality was lower and the operating time was longer, a randomized non-inferiority trial in China found.

In an analysis involving 110 patients, both types of gastroscopes had a 100% success rate for capturing routine anatomical images, which met criteria for non-inferiority (margin of -8%), reported Peng Li, MD, of the Beijing Friendship Hospital in China, and colleagues, writing in Gastrointestinal Endoscopy.

But average image quality score was significantly lower and operating time was significantly longer for disposable gastroscopes versus reusable gastroscopes.
