[Sphincter of Oddi dyskinesia]

Current situation and problems in diagnosis and treatment of sphincter of Oddi dysfunction

Sphincter of Oddi dysfunction (SOD) is a clinical syndrome referring to the loss of normal physiological function of the sphincter of Oddi with upper abdominal pain from the gallbladder and pancreas, postprandial abdominal bloating, elevation of liver or pancreatic enzymes, common bile duct dilation, pancreatitis and so on. SOD is more common in patients after cholecystectomy. Although the established criteria for diagnosing and treating SOD have been applied in clinical practice, its diagnosis and treatment have long been a controversial topic since the best diagnostic and treatment methods are still unconfirmed, partly because of its natural course, disease treatment process, and long-term follow-up outcomes that have not been determined in large controlled studies. This article briefly reviews the latest research of SOD and comprehensively analyzes the current status and existing problems in the diagnosis and treatment of SOD, with an aim to provide appropriate advice for clinicians to diagnose and treat this disease.

浅谈影响ERCP操作的制约因素

内镜下逆行性胆胰管造影术(endoscopic retrograde cholangiopancreatography, ERCP)由于具有创伤小、时间短的优点, 已在胆胰疾病的诊治方面具有举足轻重的作用, 尤其在胆总管结石、胆囊切除术后的胆管复发结石的治疗方面已经成为了首选. 但随着ERCP的广泛开展和认识的不断提高, 大量研究显示局部解剖因素, 尤其是十二指肠周围憩室、乳头嵌顿结石和乳头狭窄是影响ERCP操作成功的主要解剖因素. 同时医护患三者间的配合也是影响ERCP操作成功的重要原因. 本文系统复习相关文献资料, 对ERCP操作失败的原因作一综述.
