Peroral cholangioscopy-guided transpapillary gallbladder drainage and cholecystolithotomy in the treatment of acute cholecystitis and cholelithiasis

A 35-year-old pregnant woman presented with upper right abdominal pain and jaundice. Laboratory analysis showed leukocytosis, elevated C-reactive protein, hypertransaminasemia, and cholestasis. Endoscopic ultrasonography (EUS) revealed cholecystolithiasis, acute cholecystitis, and suspected choledocholithiasis ([Fig. 1]). The patient was referred for endoscopic retrograde cholangiopancreatography (ERCP) treatment for gallbladder drainage and choledocholithiasis removal ([Video 1]).
