Clinical impact of biliary drainage and jaundice resolution in patients with obstructive metastases at the hilum

For patients presenting with progressive liver or lymph node metastases (LM) causing obstructive jaundice, survival without adequate biliary drainage is very brief. The aim of this study was to assess the impact of endoscopic drainage for biliary obstruction secondary to LM at the hilum on subsequent administration of chemotherapy and on patient outcome. Thirty-five patients were studied and underwent insertion of plastic and/or metal stents, endoscopically (80%) or percutaneously and endoscopically (20%), to obtain complete resolution of jaundice. LM originated from colon (n = 16), gastric (n = 5), breast (n = 5), pancreatic (n = 3), and miscellaneous cancers (n = 6). Bile duct strictures were Bismuth type I–II in 13 patients and type III in 22. The overall rate of success ( i.e., complete resolution of jaundice) was 86% after a median of three procedures per patient (range, 1–7). Pruritus, jaundice, nausea, abdominal pain, and anorexia improved significantly in 88, 86, 75, 66, and 50% of cases, respectively. Overall median survival was 4 months and was 6.5 versus 1.8 months ( p < 0.05) in the groups of patients whose jaundice resolved completely versus incompletely. The type of stricture did not affect survival. Patients with colon and breast cancer who were eligible for second line chemotherapy after optimal drainage had the longest survival (12–16 months). In our patients with obstructive LM, endoscopic biliary drainage completely resolved jaundice in 86% and improved clinical symptoms and survival, thus enabling these patients to have additional chemotherapy.
