Bile infection documented as initial event in the pathogenesis of brown pigment biliary stones
Francesco M. Cetta – 1 May 1986 – Findings in two patients having brown pigment bile stones, recurrent 18 and 36 months after cholecystectomy, are reported. Present data suggest that bile infection precedes rather than follows the formation of brown stones. The present data are part of a prospective study of 600 consecutive patients who underwent operation for gallstones and in whom clinical and laboratory findings, intra‐ and postoperative bile culture and bile pH were related to the analysis of stone composition by X‐ray diffractometry and infrared spectroscopy.
