Cholecystectomy for suspected gallbladder dyskinesia.

The optimal treatment for patients with suspected biliary dyskinesia is controversial. Some studies found that cholecystectomy produced symptomatic improvement in patients with gallbladder dyskinesia (diagnosed by low gallbladder ejection fraction) while others found no significant benefit. Some studies have shown that gallbladder ejection fraction can discriminate patients who would benefit from cholecystectomy. Other studies have not confirmed this.
