A computerized analysis of prognostic variables was performed in 96 proven cases of extrahepatic bile duct carcinoma treated over a 24-year period at UCLA. Forty-nine percent of the lesions were in the upper third of the bile ducts and 47% of these were resected, for an operative mortality rate of 23% and a maximum survival rate of 4.5 years. Palliative procedures in this region were associated with a 16% mortality rate and maximum survival rate of three years. The patients whose lesions were in the middle third suffered no operative mortality rate for resection or palliation and had a 12% five-year survival rate, with the longest survivor lasting 11 years. In the lower third lesions, 67% were resected by Whipple's procedures, for an 8% mortality rate and a five-year survival rate of 28% extending to nine years. Resection of these difficult carcinomas offers the best hope of survival but must be weighed against the high operative mortality risk in those lesions located in the hilar region.
Major hepatic resections were performed on 138 patients for a variety of conditions. There was one intraoperative death. Including this patient, there were 15 deaths within 30 days of the operation (operative mortality 10.9%). Important postoperative complications were intra-abdominal sepsis (17%), biliary leak (11%), hepatic failure (8%), and hemorrhage (6%). The results of 30 resections for the benign lesions, liver cell adenoma, focal nodular hyperplasia, hemangioma, and cystadenoma showed no operative mortality and low morbidity. Of 26 patients with hepatocellular carcinoma, seven died within a month of operation. The cumulative survival of the 26 at five years was 38%, and of the 19 who survived the procedure, 51%. Poor survival followed resections for cholangiocarcinoma and "mixed tumors." The five-year cumulative survival of 22 patients who had colorectal metastases excised was 31%. Apart from a patient with carcinoid, prolonged survival was rare after resection of other secondaries and after en bloc resections for tumors directly invading the liver. Hepatic resection was of value in the management of some patients with hepatic trauma, Caroli's disease, liver cysts, and intrahepatic stones.
After resection of an adenocarcinoma of the ampulla of Vater, certain clinical and pathologic characteristics influence long-term survival. Design: Retrospective case series. Setting: Major academic medical and pancreatic surgical center. Patients: Fifty-five consecutive patients who underwent Whipple resection for ampullary adenocarcinoma from 1988 through 2001. Interventions: Pylorus-preserving Whipple resection in 32 patients and standard Whipple resection in 23 patients. Main Outcome Measures: Postoperative survival. A multivariate Cox proportional hazards model was used to determine the effects of various factors on long-term survival after resection.Results: There were no operative deaths, and all patients left the hospital. After a mean follow-up of 46.9 months, the overall 5-year Kaplan-Meier survival estimate was 67.7%. The median survival of the entire group has not yet been reached. Five-year postoperative survival estimates for node-negative (n = 32) and nodepositive patients (n=23) were 76.5% and 53.4%, respectively (P = .26). Patients whose tumors demonstrated perineural invasion (n = 12) had a 5-year survival estimate of 29.2% vs 78.8% for those whose did not (PϽ.001). On multivariate analysis, the absence of perineural invasion (PϽ.001) was an independent predictor of significantly improved postoperative survival.
A retrospective study of 97 patients with proximal bile duct cancer treated at the University of California, Los Angeles Medical Center was conducted to determine the benefits of different operative treatments. Eighty-nine patients were divided into three treatment groups: Group I, curative resection (29 patients); Group II, palliative resection (13 patients) and bypasses (8 patients); and Group III, operative intubation (39 patients). Two patients died before operation and six patients were treated without operation by percutaneous biliary decompression. High morbidity rate (53.8%) and mortality rate (69.2%) were encountered in 13 patients who had hepatic resection. Survival rates of the three treatment groups were comparable. For the 64 patients closely monitored after discharge, quality of survival was assessed according to six parameters: frequency of hospitalization for cholangitis; catheter-related problems; the percentage of days hospitalized; duration of jaundice; antibiotic requirements; and analgesic needs. Group I patients had the best qualitative survival, whereas Group II patients had the worst result when compared with either Group I (p less than 0.001) or Group III (p less than 0.005). Curative resection is recommended when it can be done without a concomitant hepatic resection. When noncurable disease is found on examination, operative intubation after dilatation is the preferred palliative measure.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
