When endoscopy pulls chestnuts out of the fire: a rare case of Mirizzi’s syndrome treated with laser lithotripsy by direct peroral cholangioscopy
Mirizzi’s syndrome is a possible complication of chronic gallstone disease and surgery remains the preferred approach for treatment in symptomatic patients [1]. An endoscopic approach is usually considered only a “bridge-to-surgery” treatment for decompressing the common bile duct (CBD) by papillotomy and stent (or nasal bile drainage) placement [2]. Here we describe the potential role of holmium laser lithotripsy under direct peroral cholangioscopy in a singular case of Mirizzi’s syndrome ([Video 1]).
Video 1 Case of Mirizzi’s syndrome treated with laser lithotripsy by direct peroral cholangioscopy.
Quality:
An 82-year-old man was admitted due to abdominal pain and jaundice. Biochemistry showed high transaminases and bilirubin levels. Computed tomography was suspicious for Mirizzi’s syndrome with a large stone between the CBD and a badly recognizable gallbladder ([Fig. 1a]). Considering the patient’s severe comorbidity (chronic obstructive pulmonary disease and heart failure) and the high risks related to surgery and anesthesiology, according to the surgeon, we performed endoscopic retrograde cholangiopancreatography (ERCP).

ERCP showed Mirizzi’s syndrome type III with cholecystobiliary fistula involving up to two-thirds of the CBD diameter with an impacted large stone ([Fig. 1b]). Stone extraction using both the retrieval balloon and the Dormia basket failed. We decided to use the SpyGlass System (Boston Scientific, Massachusetts, United States) to fragment the impacted stone with holmium laser lithotripsy (Storz 25750220, 365-μm-diameter fiber, 15 Hz/20 W). The green aiming beam allowed the stone to be targeted ([Fig. 2a]), with the laser fiber in contact with the stone until it was fragmented ([Fig. 2b]); all fragments were finally removed with the retrieval balloon ([Fig. 2c]) being able to obtain complete CBD toilette, as confirmed at cholangioscopy and cholangiography ([Fig. 2d]). No complications were reported and the patient was discharged after 3 days.

Conclusion
In conclusion, holmium laser lithotripsy through the SpyGlass System can help to remove impacted stones in the CBD, allowing to avoid surgical treatment in selected patients with Mirizziʼs syndrome.
