c. Patients needing or likely to need a cholangioscope for bile duct stone treatment, biliary stricture evaluation, or cystic duct cannulation.
d. Patients who provided written informed consent, personally or through a legal representative.
a. Patients unable to undergo endoscopic treatment due to general condition, jaw, oral, or gastrointestinal issues.
b. Patients with ASA classification class 4 or higher (severe systemic disease posing a life threat) or severe comorbidities such as congestive heart failure, severe coronary insufficiency, recent myocardial infarction (within 3 months), renal failure, liver failure, bleeding peptic ulcer, paralytic ileus, bowel obstruction, or uncontrolled diabetes.
