Endoscopic retrograde cholangiopancreatography is an important tool in the diagnosis and treatment of pancreatobiliary diseases. A critical step in this procedure is deep cannulation of the bile duct as failure of cannulation generally results in an aborted procedure and failed intervention. Expert endoscopists usually achieve a high rate of successful cannulation while those less experienced typically have a much lower rate and a greater incidence of complications. Prolonged attempts at cannulation can result in significant morbidity to patients, anxiety for endoscopists, unnecessary radiation exposure and inefficient patient care. Here we review the most common endoscopic techniques used to achieve selective biliary cannulation. Pharmacologic aids to cannulation are also discussed briefly in this review.
内镜逆行胰胆管造影术是诊断和治疗胰胆疾病的重要工具。该操作中的一个关键步骤是胆管的深度插管,因为插管失败通常会导致手术中止和干预失败。经验丰富的内镜医师通常能获得较高的插管成功率,而经验不足的医师成功率通常要低得多,且并发症发生率更高。长时间的插管尝试会给患者带来严重的发病率,使内镜医师感到焦虑,造成不必要的辐射暴露,并导致低效的患者护理。在此,我们回顾用于实现选择性胆管插管的最常见内镜技术。本综述还简要讨论了插管的药物辅助手段。
