  • Title: Cholecystectomy alleviates acalculous biliary pain in patients with a reduced gallbladder ejection fraction.
    Author: Khosla R, Singh A, Miedema BW, Marshall JB.
    Journal: South Med J; 1997 Nov; 90(11):1087-90. PubMed ID: 9386048.
    Abstract:
    BACKGROUND: We sought to determine whether a reduced gallbladder ejection fraction, (GBEF) ascertained by cholecystokinin-cholescintigraphy (CCK-CS), predicts symptomatic improvement after cholecystectomy. METHODS: Medical records of patients who had had CCK-CS as well as negative results of gallbladder ultrasonography were reviewed, and patients were contacted by telephone to determine whether they had benefited from cholecystectomy. RESULTS: There were 35 patients (33 female, 2 male) who had a decreased GBEF. Cholecystectomy was done in 30, of whom 20 (67%) had resolution of pain, 8 (27%) had partial improvement, and 2 (7%) had no change. The 5 who declined cholecystectomy included none (0%) who were pain free, 2 (40%) who had partial improvement, and 3 (60%) who had no change. The clinical outcome of the two groups was significantly different. There were 14 patients (10 female, 4 male) with a normal GBEF. The 2 patients who had cholecystectomy were asymptomatic. Of the 12 patients who did not have cholecystectomy, 9 (75%) were asymptomatic, 1 (8%) had some improvement, and 2 (17%) had no change. CONCLUSIONS: Cholecystectomy is indicated for patients with acalculous biliary pain and reduced GBEF, since symptoms will likely resolve with surgery and will persist without it. Cholecystectomy for patients with a normal GBEF should be considered only after failure of a nonoperative trial, since improvement usually occurs over time.
