Research background

This study is the first metanalysis to discover the differences between two main modalities for performing peroral endoscopic myotomy.

Research motivation

This study allows us to continue progressing in terms of instruments as it leads to continued success, but quicker and less adverse outcomes.

Research objectives

To compare two knives, conventional triangular tip as well as water jet integrated triangular tip knives.

Research methods

Clinical trials were examined and put together into metaanalysis.

Research results

This shows that water jet knife is comparable in terms of success to conventional traditional triangular knife with fewer adverse events and faster time.

Research conclusions

This study proposes new availability in instruments to the field of endoscopic myotomy.

Research perspectives

This allows future research to examine additional instruments and how to continue to further clinical success with better outcomes as well as ease for the endoscopist.
