Task: Answer Verification
Input (English): Question: Does hepaticoplasty prevent cholangitis after pancreaticoduodenectomy in patients with small bile ducts?
Answer: The ratio of postoperative reduction of the bile duct diameter to that before surgery was found to be the only risk factor for cholangitis after PD. Patients with a small bile duct of ≤15 mm in diameter preoperatively might benefit from hepaticoplasty to widen the bile duct diameter and prevent cholangitis after PD.
Output (English): yes
