Percutaneous transhepatic gallbladder drainage for acute acalculous cholecystitis following cardiovascular surgery.

Four (1.2%) out of 321 patients required percutaneous transhepatic gallbladder drainage (PTGBD) following cardiovascular surgery. Cholecystitis was initially suspected based upon the occurrence of postoperative fever and the results of abdominal X-ray films. The main physical finding was tenderness of the right upper quadrant abdomen in all patients. Spontaneous pain and Blumberg's sign were not apparent. Distension of the gallbladder and sludge in the gall-bladder were detected in all four patients by ultrasonography, but calculi were not observed. Thickening and edema of the gallbladder wall, generally suggestive of cholecystitis, were observed in only one patient. PTGBD was performed from 5 to 43 (mean 16) days after surgery. The drained fluid was concentrated bile and not purulent. High fever dropped and serum transaminase and C-reactive protein levels decreased within three days after PTGBD. Bacteriologic examinations of the bile and arterial blood were negative in all cases. No complications as a result of PTGBD introduction occurred. PTGBD is a safe and effective procedure, and therefore should be actively performed even in the early phase of acute cholecystitis.
