Mirizzi’s syndrome in Roux-en-Y bypass patient successfully treated with cholangioscopically-guided laser lithotripsy via percutaneous gastrostomy

Obesity and bariatric surgery are major risk factors in gallstone disease. In patients with a past history of Roux-en-Y gastric bypass, Mirizzi’s syndrome is a challenging endoscopic situation because of the modified anatomy. Here we report the first case of a patient with a Roux-en-Y gastric bypass treated by intracorporeal lithotripsy with a digital single-operator cholangioscope following an endoscopic retrograde cholangiopancreatography (ERCP) using a percutaneous gastrostomy access.
