Does positive hepatobiliary scan in cholecystitis stay positive, and for how long?
A prospective study of 11 patients who had undergone two sequential hepatobiliary scans prior to surgery demonstrated that initially positive scans could be due to acute cholecystitis, or chronic cholecystitis with exacerbation. A second hepatobiliary scan performed four to five days later differentiated acute from chronic cholecystitis. All five patients with surgery-proven acute cholecystitis remained hepatobiliary-positive, while patients with surgery-proven chronic cholecystitis reverted back to negative hepatobiliary scans if the second hepatobiliary scan was done properly.
