Post-Cholecystectomy Mirizzi Syndrome by Calculus in the Remaining Cystic Duct: Case Report and Review of Literature

Mirizzi Syndrome (MS) is a rare cause of biliary obstruction. While laparoscopic cholecystectomy is the standard treatment, severe inflammation often necessitates subtotal cholecystectomy to prevent bile duct injury (BDI). However, retained stones in the gallbladder remnant or cystic duct can cause recurrent obstruction, termed post-cholecystectomy Mirizzi Syndrome (PCMS).

A 34-year-old female presented with PCMS 6 years after undergoing a subtotal cholecystectomy for MS. Despite initial conservative management, definitive resolution required secondary surgical intervention.

As subtotal cholecystectomy becomes more frequent to avoid BDI, the incidence of PCMS is expected to rise. Clinicians must maintain a high index of suspicion. Management should be multidisciplinary; however, surgery remains the definitive treatment when conservative approaches fail.
