Objectives: To examine the outcomes of a hepatectomy for intrahepatic cholangiocarcinoma (IHC) and to clarify the prognostic impact of a lymphadenectomy and the surgical margin. Large series of patients who were surgically treated for IHC are scarce. Thus, prognostic factors and long-term survival after resection of IHC remain uncertain. Design: Prospective study of patients who were surgically treated for IHC. Clinicopathologic, operative, and long-term survival data were analyzed. Setting: Prospectively collected data of all consecutive patients with pathologically confirmed IHC who had undergone liver resection with a curative intent at 1 of 16 tertiary referral centers were entered into a multiinstitutional registry. Patients: All consecutive patients who underwent a hepatectomy with a curative intent for IHC (1990-2008) were identified from a multi-institutional registry. Results: A total of 434 patients were included in the analysis. Most patients underwent a major or extended hepatectomy (70.0%) and a systematic lymphadenectomy (62.2%). The incidence of lymph node metastases (overall, 36.9%) increased with increased tumor size, with 24.4% of patients with a small IHC (diameter Յ3 cm)
Background
The highest mortality rates after liver surgery are reported in patients who undergo resection for hilar cholangiocarcinoma (HCCA). In these patients, postoperative death usually follows the development of hepatic insufficiency. We sought to determine the factors associated with postoperative hepatic insufficiency and death due to liver failure in patients undergoing hepatectomy for HCCA.
Study Design
This study included all consecutive patients who underwent hepatectomy with curative intent for HCCA at two centers from 1996 through 2013. Preoperative clinical and operative data were analyzed to identify independent determinants of i) hepatic insufficiency and ii) liver failure–related death.
Results
The study included 133 patients with right or left major (n=67) or extended (n=66) hepatectomy. Preoperative biliary drainage was performed in 98 patients and was complicated by cholangitis in 40 cases. In all these patients, cholangitis was controlled before surgery. Major (Dindo III-IV) postoperative complications occurred in 73 patients (55%), with 29 suffering from hepatic insufficiency. Fifteen patients (11%) died within 90 days after surgery, 10 of them of liver failure. On multivariate analysis, predictors of postoperative hepatic insufficiency (all p<0.05) were preoperative cholangitis (odds ratio [OR]=3.2), future liver remnant (FLR) volume <30% (OR=3.5), preoperative total bilirubin level >3 mg/dl (OR=4), and albumin level <3.5 mg/dl (OR=3.3). Only preoperative cholangitis (OR=7.5, p=.016) and FLR volume <30% (OR=7.2, p=.019) predicted postoperative liver failure–related death.
Conclusions
Preoperative cholangitis and insufficient FLR volume are major determinants of hepatic insufficiency and postoperative liver failure–related death. Given the association between biliary drainage and cholangitis, the preoperative approach to patients with HCCA should be optimized to minimize the risk of cholangitis.
The rate of complications related to the non-resected colorectal tumor is very low using oxaliplatin as first line chemotherapy. Non-operative management of asymptomatic colorectal cancers with un-resectable liver metastases is a safe approach.
Additional resection of a positive proximal (BD(Marg)) , albeit associated with an increased risk of biliary fistula, offers a significant survival benefit and should be attempted whenever possible.
