Final answer:
Transduodenal sphincterotomy is an incision made in the sphincter of Oddi, which regulates the flow of bile and pancreatic juice into the duodenum, to relieve stenosis and facilitate the flow of digestive juices.
Step-by-step explanation:
Transduodenal sphincterotomy refers to the incision made into the sphincter of Oddi to relieve stenosis. The procedure involves cutting the muscle that controls the flow of digestive juices from the bile duct and the pancreatic duct into the duodenum. The sphincter of Oddi is a muscular valve located at the junction of the bile duct and pancreatic duct which regulates the flow of bile and pancreatic juice into the duodenum. The incision made during the sphincterotomy helps to relax and open the sphincter, thus alleviating any obstruction that may exist due to stenosis or stones, facilitating the flow of bile and pancreatic juices.
