A prospective study to determine the safety and effectiveness of choledochoscopy in acute cholangitis and acute suppurative cholangitis due to common bile duct stones was conducted on 70 patients. Common bile duct pressures determined on the first 20 patients showed that choledochoscopy was unlikely to cause cholangiovenous reflux. Laboratory and clinical parameters revealed that choledochoscopy did not cause septicemia, worsen cholangitis, or provoke acute pancreatitis. There was no iatrogenic injury during choledochoscopy, and the choledochoscopic views were minimally affected by cholangitis. Choledochoscopy detected overlooked stones after conventional methods of exploration of common bile ducts in 14.3% of patients and it helped to remove impacted stones in 2.9% of patients. As a result, the incidence of retained stones after choledochoscopy was 1.4%. Time spent in choledochoscopy was short, and the total postoperative septic complication rate was only 10%. There was no operative mortality. It is concluded that choledochoscopy is safe and effective in cholangitis
