Clinical determinants of suppurative cholangitis in malignant biliary tract obstruction

The purpose of this study was to find the factors predicting the supurative cholangitis in malignant biliary tract obstruction.

During the period of 1992-2003, 107 patients were operated on for malignant obstruction of the biliary tract. Obstructions were due to gall bladder cancer (n = 4), cholangiocarcinoma (n = 21) or periampullary tumor (n = 82). Sixteen patients were found to have suppurative cholangitis at laparotomy. Among the patients with suppurative cholangitis, eight were males and eight were females with a mean age of 62 (range 42-85) years. The chi-square analysis and student-t test were employed for correlation of individual risk factors with cholangitis. Stepwise logistic regression analysis was then used to identify independent risk factors.

Only seven patients with supurative cholangitis (43.8 %) had the Charcot's triad of symptoms and one had the Reynold's pentad. Six of 16 patients survived postoperatively and were discharged from hospital while nine patients died during the first hospital admission. There were five cases of death due to biliary sepsis, two cases of anastomotic leakage, one acute renal failure, and one case of intra-abdominal hemorrhage and sepsis. Multivariate logistic regression analysis showed that a number of variables can serve as independent predictors of suppurative cholangitis, namely the fever, leukocytosis, high bilirubin level and ERCP performed in preoperative period.

Identification of these risk factors may be worthwhile in the early diagnosis and treatment of the disease. Fever, high bilirubin level, leukocytosis and ERCP performed in the preoperative period were independently associated with suppurative cholangitis (Tab. 3, Ref. 20).
