An 80-year-old man was admitted for abdominal pain and jaundice. Abdominal computed tomography and endoscopic retrograde cholangiopancreatography (ERCP) revealed an impacted bile duct stone in the duodenal papilla with biliary and pancreatic duct dilatation. We safely performed an endoscopic sphincterotomy (EST) and stone extraction. Eighteen months later, the patient was readmitted with jaundice. ERCP showed retraction of the duodenal papilla with stenosis of the biliary and pancreatic duct orifices ([Fig. 1]).

We carried out biliary balloon dilatation with stent placement and pancreatic sphincterotomy for the stenosed biliary and pancreatic orifices, respectively. The patient then underwent repeat ERCPs with balloon dilatation and stent placement at 3-month intervals for biliary orifice stenosis. During the follow-up period, retraction of the duodenal papilla progressed and the duodenal lumen at the papillary level began to narrow. At 2 years after the first admission, the patient began to have sustained vomiting. A contrast study showed duodenal obstruction at the papillary level ([Fig. 2]). We carried out repeated balloon dilatation for treatment of the duodenal obstruction ([Fig. 3]). However, the duodenal obstruction continued to worsen, and, eventually, the duodenoscope could not reach the papillary level ([Fig. 4]). Owing to the patient’s clinical condition, he was not able to undergo surgical treatment; he finally died from biliary sepsis.

Papillary stenosis is one of the long-term complications of EST, with an incidence ranging between 1.9 % and 2.7 % [1] [2] [3]. Its suggested pathogenesis includes previously inadequate division of the sphincter muscle, direct thermal injury, and genetic factors such as keloid scars [1] [4] [5]. Our patient not only had papillary stenosis but also subsequent duodenal obstruction. Of course we performed a papillary pathologic examination with multiple forceps biopsies during the ERCP sessions, which enabled us to rule out malignant stricture. Although it is difficult to give an exact explanation of which additional potential pathogenic factors might be involved in a rare case, we suggest that the extensive inflammation of the duodenal papilla due to the impacted stone may have had a role in the marked and progressive scarring, leading to development of papillary stenosis and subsequent duodenal obstruction.
