ARTICLE HIGHLIGHTS
Research background

Biliary adenomas occurring in extrahepatic biliary trees are rare. Various imaging tests are difficult to distinguish from cholangiocarcinoma or cholangiolithiasis.

Research motivation

As a rare benign tumor, extrahepatic biliary adenoma is very easy to be misdiagnosed.

Research objectives

To summarize the clinical characteristics and treatment experience of nine patients with extrahepatic biliary adenoma in the First Affiliated Hospital of Xi’an Jiaotong University from 2016 to 2022.

Research methods

Our study included a total of 9 patients. Laboratory examination, disease diagnosis, treatment, pathological features and follow-up of each patient were evaluated.

Research results

Our cohort included 6 women and 3 men with a mean age of diagnosis of 65.1 years (range 46-87). Six cases of extrahepatic biliary adenomas were located in the common bile duct and 3 in the hepatic duct. All patients had biliary symptoms at first, including obstructive jaundice (4/9, 44.4%), abdominal pain (6/9, 66.7%), and fever (3/9, 33.3%). Preoperative imaging showed cholangiocarcinoma in 6 cases and cholangiolithiasis in 3 cases. All patients underwent surgical treatment and were pathologically confirmed as biliary adenomas. The postoperative symptoms of all the 9 patients were significantly improved. Seven of the 9 patients recovered well after surgery without tumor recurrence. One patient died of heart failure 2 mo after surgery. Jaundice recurred in 1 patient 8 mo after surgery, and endoscopic retrograde cholangiopancreatography and biliary stent placement were performed.

Research conclusions

Benign extrahepatic biliary tumors are rare and difficult to diagnosis preoperatively. Intraoperative choledochoscopy and timely biopsy may offer great advantages.

Research perspectives

The differential diagnosis of obstructive jaundice or cholangitis should be taken into account with extrahepatic biliary adenoma. Since cholangiocarcinoma and cholangiolithiasis do not have clear clinical and imaging features to distinguish them from extrahepatic biliary adenoma, surgical interventions including cholangiographic biopsy are very effective in diagnosis and treatment.
