Transhepatic sphincterotomy (trænz.hɪˈpæt.ɪk sfɪŋk.təˈrɒt.ə.mi) is a medical procedure used to access and treat the bile duct. The spelling of the word is complex and includes multiple syllables that are difficult to decipher without the assistance of IPA phonetic transcription. The word begins with the sound /tr/ followed by the sound /æ/ and the consonant cluster /nz/. The second word, "sphincterotomy," includes the syllable /sɪŋk/, which indicates the pronunciation of the word's root as a hard, guttural sound. Overall, the word's spelling reflects its medical complexity and specificity.
Transhepatic sphincterotomy, also known as transhepatic papillary balloon dilation, is a medical procedure performed to treat conditions related to the biliary system, specifically the bile duct and the sphincter of Oddi. The sphincter of Oddi is a circular muscle that surrounds the end of the bile duct and controls the flow of bile into the small intestine.
During a transhepatic sphincterotomy, a specialized medical instrument, typically an endoscope, is inserted through the patient's skin and into the liver. This allows the physician to access the biliary system by puncturing the hepatic duct. Once the duct is reached, a small incision is made, creating an opening that allows for direct access to the bile duct.
The purpose of this procedure is to relieve obstructions or strictures in the biliary system, which can occur due to conditions like gallstones or conditions affecting the sphincter of Oddi. By creating an opening in the sphincter, the physician can improve the flow of bile, reduce pressure in the biliary system, and alleviate associated symptoms such as pain, jaundice, or recurrent pancreatitis.
Transhepatic sphincterotomy is typically performed by experienced gastroenterologists or interventional radiologists, using imaging techniques such as fluoroscopy or ultrasound to guide the procedure. Complications of this procedure can include bleeding, infection, pancreatitis, or injury to surrounding organs. Therefore, proper evaluation and consultation with a healthcare professional are essential before considering transhepatic sphincterotomy as a treatment option.
The word "transhepatic" is derived from two Latin roots: "trans", meaning "across" or "through", and "hepatic", relating to the liver. Thus, "transhepatic" refers to a procedure or structure involving the liver.
"Sphincterotomy" is a combination of two Greek roots: "sphincter", which means a ring-like muscle that constricts or relaxes a passage or opening, and "tome", which means "cutting". In medical terminology, "sphincterotomy" refers to the surgical incision of a sphincter muscle.
Therefore, the term "transhepatic sphincterotomy" is a combination of these two terms, indicating a surgical procedure involving the cutting of a sphincter muscle through or across the liver.
