Type I Mirizzi syndrome treated by electrohydraulic lithotripsy under the direct view of SpyGlass: A case report.

BACKGROUND

Mirizzi syndrome is an uncommon clinical complication for which the available treatment options mainly include open surgery, laparoscopic surgery, endoscopic retrograde cholangiopancreatography (ERCP), electrohydraulic lithotripsy, and laser lithotripsy. Here, a patient diagnosed with type I Mirizzi syndrome was treated with electrohydraulic lithotripsy under SpyGlass direct visualization, which may provide a reference to explore new treatments for Mirizzi syndrome.

CASE SUMMARY

This paper describes a middle-aged female patient with suspected choledocholithiasis who complained for over 1 mo of intermittent abdominal pain, dark yellow urine, jaundice, and was proposed to undergo ERCP lithotomy. Mirizzi syndrome was found during the operation and confirmed by SpyGlass. Electrohydraulic lithotripsy was performed under the direct vision of SpyGlass. After the lithotripsy, the stones were extracted using the stone extraction basket and balloon. After the operation, the patient developed transient hyperamylasemia. Through a series of symptomatic treatments (such as fasting, fluids and anti-inflammation medications), the symptoms of the patient improved. Finally, laparoscopic cholecystectomy or open cholecystectomy was performed after a half-year post-operatively.

CONCLUSION

Direct visualization-guided laser or electrohydraulic lithotripsy with SpyGlass is feasible and minimally invasive for type I Mirizzi syndrome without apparent unsafe outcomes.
