Although endoscopic sphincterotomy (EST) has a positive therapeutic effect on biliary-type sphincter of Oddi dysfunction (SOD), some patients still have little relief after EST, which implies that other functional abdominal pain may also be present with biliary-type SOD and interfere with the diagnosis and treatment of it.
This study explored the efficacy of EST in the treatment of biliary-type SOD and analyzed the reasons for the uncertainty of the efficacy of EST in the treatment of this kind of patients, that is, with FGID. The combined treatment of this kind of patient is the key to improve the efficacy of EST in the treatment of biliary-type SOD.
The objective was to investigate the therapeutic effect of EST in biliary-type SOD and analyze the reasons for the uncertainty of its curative effect to improve the curative effect of endoscopic therapy in this type patients.
This study compared and analyzed the clinical remission of different types of SOD patients after EST, including indicators such as postoperative pain, transaminase recovery and so on. The follow-up time was long, and the number of cases was sufficient.
This study suggested that EST is a minimally invasive, safe and effective treatment. For patients with type I and II SOD combined with FGID, single EST or medical treatment has limited efficacy. It is recommended that EST and medicine be combined to improve the cure rate of such patients. There are deficiencies in this study, but it is mainly a retrospective study. It is difficult to accurately diagnose SOD in patients with FGID, and more prospective randomized trials are needed to confirm.

There is a close relationship between FGID and biliary-type SOD, and more pro
