Non-visualization of gallbladder in hepatic scintigraphy is suggestive of:
(A) Chronic cholecystitis (B) Carcinoma gallbladder (C) Acute cholecystitis due to gallstones (D) Gallstones obstructing CBD
(C) Ans: C. Acute cholecystitis due to gallstones(Ref. Sabiston 20/e p1488, 19/e pi 462, Schwuz 10/e p1315, 1320, Bailey 27/c 1)1192. 26/ep1101. Hlumgari 5/e p254-270: Shackelford 7/e p 1306)Non-visualization of gallbladder in hepatic scintigraphy is suggestive of Acute cholecystitis.HIDA Scan:Allows visualization of biliary tree & gall bladder.GB visualized within 30 min of isotope injection in 90% of normal individuals and within 1 hour in the remainder.Bowel is usually seen within 1 hour in majority of patientse.Non-visualization of GB:Suggestive of acute cholecystitis.(Sensitivity & specificity-95%).Delayed/reduced visualization of GB:Suggestive of chronic cholecystitis.Due to contracted gall bladderBiliary scintigraphy:Helpful in diagnosing bile leaks & iatrogenic biliary obstruction.Confirms presence & quantifies leakage.
