Sphincterotomy is a surgical procedure in which the sphincter muscle, typically in the biliary system or anus, is cut to relieve obstruction or treat conditions like bile duct stones or sphincter of Oddi dysfunction. It is often performed endoscopically.

In the biliary system, sphincterotomy is used to remove bile duct stones or improve bile flow in cases of obstruction. This procedure can be done using an endoscope inserted through the duodenum to cut the sphincter muscle and allow better drainage of bile.

Postoperative care involves managing any pain or infection, monitoring for complications, and following dietary guidelines to support digestive health. Most patients experience a significant reduction in symptoms like pain and jaundice.

Sphincterotomy offers an effective and minimally invasive treatment for biliary and gastrointestinal conditions, improving bile flow and preventing future complications such as recurrent stones or bile duct obstructions.
