Reflux of duodenal contents and cholangitis after endoscopic biliary sphincterotomy To the Editor: There is a Latin expression that defines some form of cholangitis, possibly from duodenobiliary reflux, cholangitis sine materia (bile infection without any stuff), that is, cholangitis without obstruction of the biliary tree (for instance due to common bile duct stones or strictures). This has been seen after surgical procedures, like choledochoduodenostomy, in which a large opening remains between the common bile duct and the duodenal bulb, or with surgical biliary sphincteroplasty in the papilla of Vater. Under such circumstances, it is easy for duodenal contents to enter into the biliary tree and cause contamination. Interestingly, Misra and Dwivedi1 did not find this phenomenon (cholangitis sine materia) in patients having stents crossing the papilla that were used to palliate malignant obstructive jaundice. But the life span of www.giejournal.org
patients with neoplasia is limited compared with others having benign biliary conditions. Furthermore, duodenobiliary reflux can be of solid2 or semisolid content and remain within the bile duct, causing debris and making a nest for stone-like material. Misra and Dwivedi1 found that cholangitis occurred in these circumstances. Since 1973, endoscopic biliary sphincterotomy (EBS) is the standard of treatment for common bile duct stones and other papillary problems, such as sphincter of Oddi dysfunction. The extent of EBS should be tailored to the specific problem to treat. But it is not uncommon that large orifices remain after EBS. In my experience, problems related to duodenobiliary reflux are not an infrequent cause for ERCP reintervention. In order to preserve sphincter of Oddi function, endoscopic papillary balloon dilation was proposed some years ago. Unfortunately, the good results achieved in Eastern countries3 have not been reproduced in the United States and Europe.4,5 However, if we cannot close the gate completely after stone extraction, as it occurs with endoscopic papillary balloon dilation, we can prevent it from remaining wide open. The advent of performing a limited EBS extent, followed by large-diameter balloon dilation,6,7 can be a successful half-way measure, perhaps reducing the likelihood of duodenobiliary reflux and its complications.
