Catheter tract implantation metastases associated with percutaneous biliary drainage for extrahepatic cholangiocarcinoma

Figure 1 The cumulative incidence of catheter tract implantation metastasis after percutaneous transhepatic biliary drainage among 67 patients who underwent resection of extrahepatic cholangiocarcinoma.

Figure 2 Kaplan-Meier estimates of survival after the detection of catheter tract implantation metastasis among nine patients with documented outcomes (Table 1). The median survival time was not reached with a cumulative 1-year survival rate of 80% in patients with isolated implantation metastasis, whereas it was 9 mo with that of 25% in patients with non-isolated metastasis. Patients with isolated implantation metastases survived longer than patients with non-isolated implantation metastases (P = 0.0457).
