Endoscopic biliary drainage by 7 Fr or 10 Fr stent placement in patients with acute cholangitis

Abstract

Background and Study Aims: Endoscopic biliary drainage is an established mode of treatment for acute cholangitis. We compared the safety and efficacy of 7 Fr and 10 Fr stent placement for biliary drainage in patients with acute cholangitis. Patients and methods: We recruited 40 patients with severe cholangitis who required endoscopic biliary drainage. Patients were randomized to have either a 7 Fr or a 10 Fr straight flap stent placement during endoscopy. Outcome measures included complications related to endoscopic retrograde cholangiopancreatography (ERCP) and clinical outcome. Results: Of 40 patients, 20 were randomized to the 7 Fr stent group and 20 to the 10 Fr stent group. All patients had biliary obstruction due to stones in the common bile duct. Indications for biliary drainage were: fever >100.4°F (n = 27), hypotension (n = 6), peritonism (n = 10), impaired consciousness (n = 8), and failure to improve with conservative management (n = 13). Biliary drainage was achieved in all patients. Abdominal pain, fever, jaundice, hypotension, peritonism, and altered sensorium improved after a median period of 3 days in both groups. Leukocyte counts became normal after a median time of 4 days in the 7 Fr stent group and 6 days in the 10 Fr stent group. There were no ERCP-related complications. There were no instances of occlusion or migration of stent. The success rates of biliary drainage in cholangitis were not affected by the size of stent used. Conclusions: Biliary drainage by 7 Fr stent or 10 Fr stent is equally safe and effective treatment for patients with severe cholangitis.
