Summary

Foreign bodies, particularly surgical clips, can cause iatrogenic biliary stones by acting as a nidus for formation. Understanding their migration and formation mechanisms is crucial for managing these complications.

Area of Science:

  • Gastroenterology
  • Surgical Pathology

Background:

  • Biliary stone disease is common and can lead to serious complications.
  • Foreign bodies (FBs) frequently serve as a nidus for biliary stone formation.
  • Surgical clips are the most common iatrogenic FBs causing biliary stones.

Purpose of the Study:

  • To review literature on iatrogenic biliary stones caused by FBs.
  • To discuss mechanisms of FB migration and stone formation.
  • To outline clinical presentations and management strategies.

Main Methods:

  • Literature review of foreign body-induced biliary stones.
  • Analysis of postulated mechanisms for FB migration.
  • Synthesis of clinical data on presentation and management.

Main Results:

  • Surgical clips are frequently implicated in iatrogenic biliary stone formation.
  • Potential migration pathways include direct surgical introduction, penetrating injuries, and entero-biliary reflux.
  • Clinical presentation often involves biliary obstruction and cholangitis, occurring years post-surgery.

Conclusions:

  • Foreign bodies, especially surgical clips, are a significant cause of iatrogenic biliary stones.
  • The exact mechanisms of FB migration remain unclear but several theories exist.
  • Effective management requires understanding these mechanisms for timely diagnosis and treatment.
