Need to identify the risk factor for stone recurrence after common bile duct exploration.

Choledocholithiasis and cholecystitis are among the most common surgical conditions in the hepato-pancreato-biliary section. The recurrence of common bile duct (CBD) stones is considered an unsolved problem after cholecystectomy. In the setting of recurrent CBD stones, the management approach is regular follow-up after surgery in patients with the risk factors of recurrence. Many contributing factors also predispose the patient to the formation of recurrent primary CBD stones. Therefore, it is essential to evaluate the more influential risk factors and their role in predicting the occurrence of CBD stones.
