Biliary Pigment and Cholesterol Calculi in Patients with and Without Juxtapapillary Duodenal Diverticula
The occurrence of pigment and cholesterol calculi was studied in 45 patients with concrements in the gallbladder but no calculi in the common or intrahepatic bile ducts. Twenty-one of the patients had juxtapapillary duodenal diverticula diagnosed by duodenoscopy. Twenty-four patients had no divertic...

Zusammenfassung: | The occurrence of pigment and cholesterol calculi was studied in 45 patients with concrements in the gallbladder but no calculi in the common or intrahepatic bile ducts. Twenty-one of the patients had juxtapapillary duodenal diverticula diagnosed by duodenoscopy. Twenty-four patients had no diverticula. The classification of the calculi as pigment stones or cholesterol stones was based on quantitative determination of the cholesterol contents. Calculi with a cholesterol content of less than 25% were classified as pigment stones; calculi with a cholesterol content of more than 25% were classified as cholesterol stones. All pigment stones had a cholesterol content of less than 20%. With the exception of four patients the cholesterol content was over 70% in all cholesterol stones. Twelve of the 21 patients with diverticula had pigment stones, whereas only 1 of the 24 patients without diverticula had pigment calculi, a difference that was statistically significant (p < 0.01). |
