Clinical value of preoperative biliary drainage for the outcomes of pancreaticoduodenectomy in the patients with jaundice caused by malignant obstruction hi the low bile duct / 中国综合临床

ABSTRACT

Objective To investigate the effects of preoperative biliary drainage ( PBD ) on the morbidity and mortality of pancreaticoduodenectomy in patients with malignant obstructive jaundice in the lower bile duct. Methods Clinical data of 74 cases undergoing pancreaticoduodenectomy from Jan. 2000 to Dec. 2005 with preoperative total bilirubin level over 85 μmol/L were collected and retrospectively analyzed. Comparison was performed between patients receiving PBD and those not. Before surgery. The parameters sincluding perioperative situation, in-hospital death rate, post-operative complications and were calculated to evaluate the influence of pre-operative biliary drainage on the outcomes. Univariate analysis and Logistic analysis were used to identify the risk factors for post-operative complications. Results Forty (40/74) cases received PTCD procedure. The total bilirubin was significantly reduced from (338. 10±88. 38 )μwnol/L to ( 228. 50±82.24) μ,mol/L in PTCD population and was significantly lower than ( 328. 60±93. 02) μmol/L of the non-PTCD group. There was no significance between the two groups in terms of total complications and individual complication Logistic regression analysis showed that preoperative TB over 340 μmol/L and blood loss over 600 ml were important risk factors for post-operative complications. Conclusion High pre-operative total bilirubin over 340 μmol/L increases the risk of post-operative complications in the patients with malignant jaundice. Preoperative biliary drainage is useful to reduce the total bilirubin and improve the hepatic function of the patients. Prolonged pre-operative biliary drainage could be considered in the patients with high preoperative bilirubin,poor nutritional condition and impaired coagulation to enhance the tolerance of surgery.
