“Dropped stone” after cholecystectomy

                         The development of abscesses from dropped stones is probably related to the significant bacterial content gallstones. It has been shown that bacteria also have an adhesive property that facilitates pigment stone formation. This correlates with the finding that most abscesses due to dropped stones are found in association with calcified stones. Another explanation may be that infected bile causes these abscesses. The diagnosis is often made by CT imaging. Acalcified nidus is often identified within the abscess. If the stone is not calcified, the etiology of the abscess may be initially unclear.
