Background
A gallbladder ejection fraction (EF) on cholescintigraphy of less than 35% after cholecystokinin (CCK) has been considered to be pathophysiologic and an indication for laparoscopic cholecystectomy (LC).
Methods
All patients undergoing LC for biliary dyskinesia between 1994 and 2001 were prospectively entered into a database. These patients were retrospectively evaluated with regard to demographics, the number of preoperative studies obtained, postoperative symptoms, and the number of postoperative studies obtained.
Results
Sixty patients underwent LC for biliary dyskinesia. The mean gallbladder EF was 14%, and 75% of patients were asymptomatic postoperatively. Persistent symptoms prompted further investigation in 6% of patients with a gallbladder EF <14% and in 35% of patients with an EF between 14 and 35% (p = 0.05).
Conclusion
Laparoscopic cholecystectomy alleviated symptoms in 94% of patients with a gallbladder EF <14% after CCK injection. The diagnostic significance of a preoperative CCK cholescintigram (EF 14–35%) needs further investigation.
