Purpose:
Mucin-producing intrahepatic biliary papillomatosis (MPIBP) is an uncommon tumor. The purpose of this study was to evaluate the clinical, radiological, and histopathological characteristics of MPIBP, and its prognosis.
Methods:
A retrospective analysis was conducted of 11 patients who underwent surgery for MPIBP. The clinical features and radiological, pathological, and operative findings were reviewed, and the survival rates were determined.
Results:
Repeated episodes of fever and epigastric pain with or without jaundice were the common clinical manifestations. Radiologically, all patients showed diffuse bile duct dilatation with cystic change in intrahepatic bile duct. All patients underwent a hepatic resection with or without an extrahepatic bile duct resection. No in-hospital mortality occurred. All patients survived without any signs of recurrence (median 12 +/- 7 months); three patients, including two patients who underwent a palliative resection, had an attack of cholangitis, which was effectively treated with antibiotics.
Conclusions:
A diagnosis of MPIBP is usually made in patients with biliary dilatation following a radiologic study. Magnetic resonance cholangiopancreatography is more valuable than other modalities in diagnosis. Mucin-producing intrahepatic biliary papillomatosis is a premalignant disease with high malignant potential. The prognosis of MPIBP is excellent if an aggressive resection is performed. A combination of cholangioscopy and frozen sections during the operation is beneficial for a radical successful surgical resection.
Insights
Mucin-producing intrahepatic biliary papillomatosis (MPIBP) is a premalignant bile duct tumor. Aggressive surgical resection offers an excellent prognosis for patients with MPIBP, with no recurrence observed in this study.
Area of Science:
- Hepatobiliary surgery
- Gastroenterology
- Surgical oncology
Background:
- Mucin-producing intrahepatic biliary papillomatosis (MPIBP) is a rare tumor of the bile ducts.
- Understanding its characteristics is crucial for effective management.
Purpose of the Study:
- To evaluate the clinical, radiological, and histopathological features of MPIBP.
- To assess the prognosis of patients with MPIBP following surgical intervention.
Main Methods:
- Retrospective analysis of 11 patients who underwent surgery for MPIBP.
- Review of clinical, radiological, pathological, and operative findings.
- Determination of survival rates and recurrence patterns.
Main Results:
- Common symptoms include fever, epigastric pain, and jaundice.
- Radiological findings consistently showed diffuse bile duct dilatation with cystic changes.
- All patients underwent hepatic resection; no in-hospital mortality occurred, with a median survival of 12 months without recurrence.
Conclusions:
- MPIBP is often diagnosed based on biliary dilatation seen in imaging studies, with MRI being particularly valuable.
- MPIBP is a premalignant condition with high malignant potential.
- Aggressive surgical resection leads to an excellent prognosis; intraoperative cholangioscopy and frozen sections aid successful radical resection.
