Incidence of cholelithiasis among patients with cirrhosis and portal hypertension.

Abstract

One hundred and two patients with cirrhosis and portal hypertension were evaluated sonographically to determine the presence or absence of cholelithiasis. The gallbladder was visualized in 80 of 102 patients. Cholelithiasis was present in 43 of 80 cases (54%). All 22 patients in whom the gallbladder was not seen sonographically had had a previous cholecystectomy. Five of them were operated on prior to development of cirrhosis with portal hypertension, but 14 of the remaining 17 (82%) had evidence of cholelithiasis at pathology. Hence, there was an overall incidence of cholelithiasis of 59% among out 97 patients. This study as well as previous autopsy data indicate an increased incidence of cholelithiasis in patients with cirrhosis, irrespective of etiology or sex. The incidence of cholelithiasis in this study, however, was approximately twice that previously reported in cirrhotics at autopsy. Furthermore, patients with portosystemic shunts showed a significantly higher incidence of cholelithiasis compared to patients who were not shunted (68% vs 49%, p = 0.028). We believe the severity and duration of cirrhosis in our patient population, all with documented portal hypertension, may be the cause of this increased incidence.
