| Popis: | Introduction: Although measuring the pressure of the sphincter of Oddi and the bile duct is considered to be an important examination, called Sphincter of Oddi manometry (SOM), some complications related to the SOM device remain unsolved.Material and methods: To decrease adverse complications, we developed a 0.46 mm manometry and we performed some in vitro studies.Results: We successfully developed a 0.46 mm SOM. The diameter is the thinnest size used in endoscopic examinations. The results of in vitro studies show the suitability as SOM.Conclusion: This device will decrease the risks related to SOM examination. To confirm the safety and feasibility, further studies including in vivo studies will be needed. |
