Out of sight but kept in mind: complications and imitations of dropped gallstones.

Objective: The purpose of this article is to describe the diagnostic pitfalls caused by dropped gallstones left in situ after laparoscopic cholecystectomy.

Conclusion: Dropped gallstones may rarely become symptomatic, causing recurrent abscesses. Diagnosis is challenging due to unusual clinical presentations, myriad locations, and radiologically occult calculi.
