Obstructive jaundice is very common in hepatobiliary and pancreatic surgery clinics. The common causes of obstructive jaundice are gallstones, bile duct strictures and tumors. The obstruction caused by the first two diseases is mostly incomplete, and the patient’s jaundice is not deep; the bile duct obstruction caused by tumor is mostly complete, and the jaundice is mostly progressively aggravated. Obstructive jaundice has a certain damage to the patient’s liver, kidney function and coagulation function. Surgical treatment of obstructive jaundice is required in the vast majority of patients. The question is whether preoperative treatment is always necessary to reduce jaundice? There has been a debate on this issue. In recent years, the surgical community has favored the preoperative management of total bilirubin >500 μmol/l. The common methods of preoperative yellowing reduction include: PTBD, ENBD, and internal drainage via ERCP stent. In recent years, the surgical community does not agree with preoperative yellowing reduction. Our group does not support preoperative yellowing reduction, and the majority of patients do not require preoperative yellowing reduction, except for those with hepatic or renal dysfunction and coagulation. Most of the patients, once the yellow reduction is successful, delay the surgery or give up the surgery due to reluctance to undergo surgery, throwing away the opportunity for radical treatment. Here, we remind patients or their families that preoperative yellowing reduction is a temporary measure before surgery, not a radical treatment, because the tumor has not been removed; furthermore, transcatheter lower bile duct cannulation usually lasts for 3 months, after which recurrent fever and other manifestations of incomplete obstruction can occur. The benefits of not doing preoperative yellowing reduction are as follows: 1. early surgery, early opening of the bile duct and complete decompression and drainage; yellowing reduction and tumor resection can be completed at one time; 2. bile duct expansion is beneficial to bile-intestinal anastomosis, large anastomotic caliber, postoperative anastomosis is unobstructed and not narrowed, with good long-term results; 3. intraoperative bleeding tendency can be used hemostatic drugs, prothrombin complex, etc. to ensure the successful completion of surgery. A few years ago, I successfully completed the surgery for a patient with preoperative total bilirubin >700μmol/l; 4.Postoperative liver protection and biliary benefit to promote rapid recovery of liver function. The use of Chinese herbal medicine Yin Chen Tang can help eliminate postoperative yellowing. The effect of obstructive jaundice on liver function is reversible, and it recovers quickly after surgery. The problem is this: when the jaundice is not severe, the lesion can be successfully (or even easily) resected, and the patient can tolerate the conditions of surgery, there is no need for yellowness reduction treatment. Never do a reduced-yellowing treatment, let alone repeatedly change the tube without surgery missing the opportunity to operate. Come to the hospital for surgery at an early stage to completely remove the tumor, live tumor-free, improve the quality of survival, and take a quick route of diagnosis and treatment, which can save money and achieve the treatment effect of radical cure.
