A case of Mirizzi syndrome treated with electronic hydraulic lithotripsy

A 72-year-old female who was admitted to our hospital for jaundice received the diagnosis of cholangitis based on blood test and abdominal CT findings. We performed biliary drainage by placing a stent via endoscopic retrograde cholangiography (ERC). After the cholangitis improved, we attempted to remove the stone using a catheter but were unsuccessful. Cholangiography showed the stone in the cystic duct, and Mirizzi syndrome was diagnosed. We planned an electronic hydraulic lithotripsy (EHL) but replaced the stent several times due to occlusion or displacement. On Day 43 from the first visit, we used EHL to crush and remove the stone in the cystic duct. The post-operative course was uneventful, and the cholangitis has not recurred.
