Core Tip
Core Tip: Mirizzi syndrome (MS) type Vb is an exceptionally rare and advanced form of gallstone disease characterized by a cholecystoenteric fistula. We report a unique case of MS type Vb complicated by a cholecystogastric fistula leading to fixed gastric outlet obstruction. Unlike typical gallstone migration, obstruction in this case was caused by irreversible inflammatory and cicatricial deformation of the pyloroduodenal region. This report highlights diagnostic challenges, the limitations of preoperative imaging, and the need for individualized surgical decision-making in advanced MS.
