Does hepaticoplasty prevent cholangitis after pancreaticoduodenectomy in patients with small bile ducts?
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.
In normal tension glaucoma, the ganglion cells dysfunction is present and can be detected with PERG test. PERG can be additional useful diagnostic test in patients with normal tension glaucoma, particulary for those with difficult to cooperate.
