Gallbladder stones were treated using a novel chemical method. A complication of cystic duct blockage was successfully resolved with endoscopic lithotripsy, restoring bile flow.

Area of Science:

  • Gastroenterology
  • Interventional Radiology
  • Hepatobiliary Surgery

Background:

  • Gallbladder stones (cholelithiasis) are common, often requiring intervention.
  • Percutaneous transhepatic chemolitholysis using methyl-tert-butyl-ether (MTBE) is an option for dissolving gallbladder stones.
  • Potential complications include ductal obstruction.

Observation:

  • A patient underwent pump-controlled percutaneous transhepatic chemolitholysis for multiple gallbladder concrements.
  • A calcified residual stone acutely blocked the cystic duct near treatment completion.
  • The blockage necessitated a secondary intervention.

Findings:

  • The cystic duct obstruction was successfully managed by reopening the puncture track with a bougie.
  • Subsequent endoscopic lithotripsy effectively cleared the obstructing calcified stone.

  • The cystic duct was rendered passable, resolving the acute blockage.

    • Implications:

    • This case highlights a rare complication of MTBE chemolitholysis for gallstones.
    • It demonstrates the successful use of a combined approach (bougie dilation and endoscopic lithotripsy) to manage acute cystic duct obstruction.
    • This strategy may be valuable in similar challenging clinical scenarios involving retained or obstructing gallbladder fragments.
