A rare extraction basket impaction: tracing back to biliary tract surgery 10 years ago

A 79-year-old man was hospitalized due to abdominal pain. The patient had a prior history of choledocholithotomy with T-tube drainage, which was performed 10 years earlier, along with three endoscopic retrograde cholangiopancreatography (ERCP) procedures within the past 4 years. Magnetic resonance imaging demonstrated a large stone, approximately 20 × 13 mm, in the distal common bile duct ([Fig. 1]). After a multidisciplinary discussion, ERCP was selected as the optimal intervention for stone removal.
