How should obstructive jaundice be treated? Currently, percutaneous percutaneous hepatic choledochal drainage (PTCD) technique is generally used, so is it effective? Here to see: Percutaneous hepatic perforated biliary drainage (PTCD) has been more commonly used in clinical practice, PTCD can be performed for patients with obstructive jaundice to reduce pressure, reduce yellowness, relieve symptoms, improve general condition, perform elective surgery, increase surgical safety, reduce complications, and reduce mortality. Palliative biliary drainage can be performed in the treatment of malignant biliary obstruction caused by tumors. It is particularly suitable for elderly patients, those with physical failure, poor systemic condition and important organ insufficiency. Through clinical work, I suggest to combine intraoperative biliary stent implantation as much as possible, which can greatly increase the effect of yellowing and decompression, shorten the recovery time of liver function, and improve the quality of survival of patients.
