Biliary Dyskinesia –“Only in America”

In a recent commentary from Gastroenterology & Endoscopy News (, Moshe Schein reviews a recent study regarding biliary dyskinesia (BD) (Am J Surg 2015; 209: 799-803) which highlights that almost 20% of cholecystectomies in the U.S. are for noncalculous disease.

Key points:

  • The number of cholecystectomies for BD increased from 43.3 to 89.1 per 1 million between 1991-2011.
  • BD is “almost unheard of” in all other parts of the world.  “The majority of surgeons practicing outside the United States maintain that BD is a myth…Measuring gallbladder ejection fraction is something that they never do.”

My take: this is an area in need of a large randomized controlled trial.  Perhaps biliary dyskinesia will share the same fate as sphincter of Oddi dysfunction.
