Percutaneous self-expandable uncovered metallic stents in malignant biliary obstruction. Complications, follow-up and reintervention in 154 patients.
Acta Radiologica 2003 March
PURPOSE: Evaluation of technique, complications and the long-term follow-up data of 154 patients with inoperable malignant biliary obstruction who underwent percutaneous placement of metallic stents.
MATERIAL AND METHODS: During a 6-year period, 224 self-expanding metallic stents (150 biliary Wallstents and 74 Memotherm nitinol stents) were inserted in 154 patients with inoperable malignant biliary obstruction. 100 patients had obstructions at the proximal (supracystic) level, and 54 at the distal (infracystic) level. The causes of obstructions were hilar cholangiocarcinoma (n = 64), pancreatic carcinoma (n = 34), gallbladder carcinoma (n = 24), metastatic carcinoma (n = 21), common bile duct carcinoma (n = 8), and hepatocellular carcinoma (n = 3). A complete follow-up was available for all patients.
RESULTS: The 30-day mortality was 9%, with no procedure-related deaths. The clinical success rate within the first 30 days was 88%. The total rate of early, procedure-related complications was 28%, and half of them were due to the percutaneous transhepatic catheter drainage procedure. Recurrent jaundice occurred in 28 (18%) patients and in 23 (82%) of these, reinterventions were made in order to relieve reobstructions. The mean length of survival for the entire patient group was 4 months, while the mean period of patency for all stents was 6 months. We found no statistically significant difference in patient survival or stent patency periods in regard to the level and cause of obstruction.
CONCLUSION: Percutaneous metallic stent placement maintains equal palliation in patients with proximal and distal malignant biliary obstructions caused by any tumor type. Most of the early complications were due to procedures performed before stent insertion and could be decreased by direct stent insertions. The most common late complication, reobstruction, is inevitable but can be easily treated in the majority of patients.
