Abstract
Background: To assess hepatobiliary (HB) scans for predicting recurrent symptoms in nonoperated patients with
mild or vague symptomatic gallstones.
Methods: Data of 170 patients with symptomatic gallstone and who had not undergone cholecystectomy were
retrospectively enrolled. These patients were divided into two groups according to whether or not operations were
performed due to recurrent symptoms during the follow-up period. The demographic factors and gallbladder
ejection fraction (GBEF) of HB scans were compared between the groups. Additionally, symptom-free rate was
obtained beginning from the date of the HB scan to the date of surgery, and analyzed based on the level of GBEF.
Results: Among the 170 enrolled patients, two patients who underwent cholecystectomy for other disease were
excluded. Thirty-four patients underwent cholecystectomy due to recurrent symptoms (OP group), and the remaining
136 patients did not experience recurrent symptoms and therefore did not undergo cholecystectomy (non-OP group).
In the OP group, the mean GBEF was significantly lower than that of the non-OP group (28.8 ± 29.9 vs. 66.3 ± 20.0;
P < 0.001). The rate of lower GBEF (<30 %, including non-visualization of the gallbladder) was significantly higher
in the OP group than the non-OP group (54.9 vs. 5.1 %; P < 0.001). In patients with non-visualization of the
gallbladder or GBEF <30 %, the 10-year symptom-free rate was significantly lower than those with a GBEF ≥ 30 %
(19.8 % vs. 81.9 %; P < 0.001).
Conclusion: HB scanning is a useful objective modality to differentiate gallstone-related symptoms from other
etiologies and predict recurrent symptoms.
