Nineteen patients with distal juxtapapillary choledochoduodenal fistula diagnosed by endoscopic retrograde cholangiopancreatography are reported. Eighty-four percent of the patients had undergone previous operations on the biliary tract. Fistula appears to be mostly secondary to common bile duct exploration with rigid probes or to a technical mistake in performing sphincteroplasty. Spontaneous fistula secondary to the passage of a stone into the duodenal lumen may also occur. Common duct stones were responsible for the symptoms in most cases (70%). Endoscopic sphincterotomy showed good results in cholecystectomized patients with stones. Surgery directed to the fistula or biliary by-pass are not recommended. Uncomplicated fistula probably does not require treatment.
