The Biliary Obstruction Rescuer: How Does Percutaneous Hepatobiliary Drainage Work?
Biliary duct obstruction can lead to serious health problems, and percutaneous hepatobiliary drainage (PTHC) is a reliable way to solve this problem.
In modern medicine, percutaneous hepatobiliary drainage (PTHC), as a slightly invasive technique, has become an important means to solve biliary obstruction. With this technology, doctors are able to effectively visualize the anatomy of the biliary tract and perform necessary interventions in the bile duct. The history of this technique dates back to 1937, but it gradually became popular after 1952 and became a common clinical procedure.
This technique has a variety of uses, including draining bile or infected bile to relieve obstructive jaundice, inserting stents to dilate biliary strictures, remove gallstones, and even in some cases, perform a similar procedure to endoscopic techniques. combined surgery. This "convergence technique" requires professional guidance devices to ensure the success of the surgery. In addition, PTHC has also been used to estimate the drainage of unruptured or uncomplicated hydatid cysts.
Even if PTHC is banned in certain circumstances, such as when bleeding tendencies are evident, it remains a valuable technology.
Before considering PTHC, doctors will carefully examine the patient's condition to ensure there are no contraindications. Contraindications include bleeding tendencies, platelet counts below a certain value, and cases of biliary infection, for which PTHC is generally not recommended except for drainage under infection control. After it is determined that the surgery can be performed, a contrast medium with a low osmolarity is used.
Patients are fasted for four hours before this procedure and may receive prophylactic antibiotics to reduce the risk of infection during surgery. During the surgery, the patient's vital signs also need to be monitored to ensure safety. Ultrasound examination is an important step before the procedure to ensure that the puncture point is marked correctly so that the biliary tract can be more precisely located.
Although percutaneous hepatobiliary drainage carries lower risks than endoscopic biliary drainage, it still needs to be evaluated with caution.
After the surgery, some complications may occur, including allergic reactions, pancreatitis, and perforation of the T-tube path. Although the complication rate of PTHC is lower compared with endoscopic biliary drainage, it still needs attention. The success rate of the operation is usually related to the degree of dilation of the biliary tract and the number of punctures.
Percutaneous hepatobiliary drainage is sometimes used to treat unsuccessful biliary surgery, such as when major changes have occurred in the stomach or small intestine, including gastrectomy for Bill Ross type II. This makes the removal of some gallstones more complicated, requiring a doctor to evaluate the best treatment options.
Patients after surgery need to be supervised by doctors and maintain appropriate rest to confirm the success of the surgery.
Also, in T-tube technique, T-tube cholangiography is performed on the tenth postoperative day to determine the presence of any leakage or stones in the biliary tract. This procedure is an important step in percutaneous hepatobiliary drainage, which ensures the health of the biliary tract through drainage of the glands.
Although percutaneous hepatobiliary drainage is an effective treatment, the patient's health and the risks associated with the procedure need to be carefully assessed before proceeding. As medical technology continues to advance, PTHC will continue to play a key role in life.
So, when we face such a critical medical technology, should we re-evaluate our understanding and attitude towards the treatment of biliary tract diseases?
