Intraductal papillary neoplasm of the bile duct

Intraductal papillary neoplasm of the bile duct (IPNB) is a variant of bile duct carcinoma that is characterized by intraductal growth and better outcomes compared with common cholangiocarcinoma. IPNBs are mainly found in patients from Far Eastern areas, where hepatolithiasis and clonorchiasis are endemic. According to the immunohistochemical profiles of the mucin core proteins, IPNBs are classified into four types: pancreaticobiliary, intestinal, gastric, and oncocytic. Approximately 40%-80% of IPNBs contain a component of invasive carcinoma or tubular or mucinous adenocarcinoma, suggesting that IPNB is a disease with high potential for malignancy. It is difficult to make an accurate preoperative diagnosis because of IPNB’s low incidence and the lack of specificity in its clinical manifestation. The most common abnormal preoperative imaging findings of IPNB are intraductal masses and the involvement of bile duct dilation. Simultaneous proximal and distal bile duct dilation can be detected in some cases, which has diagnostic significance. Cholangiography and cholangioscopy are needed to confirm the pathology and demonstrate the extent of the lesions. However, pathologic diagnosis by biopsy cannot reflect the actual stage in many cases because different foci may be of different stages and because mixed pathologic findings may exist in the same lesion. Surgical resection is the major treatment. Systematic cholangioscopy with staged biopsies and frozen sections is recommended during resection to ensure that no minor tumors are left and that curative resection is achieved. Staging, histologic subtype, curative resection and lymph node metastasis are factors affecting long-term survival.

Successful photodynamic therapy for biliary papillomatosis: A case report

Papillomatosis of the bile duct is a rare disease with a high risk of malignant transformation. Therapeutical options include partial hepatectomy and liver transplantation. A previously healthy 65-years old male developed jaundice and right upper abdominal quadrant pain in 1996. A villous adenoma of the distal bile duct was diagnosed. A Whipple procedure was performed. In 2002 the patient turned symptomatic again. Another adenoma was found in the right hepatic duct resulting in a right hepatectomy. Two years later the patient again developed cholestasis. After drainage of the left hepatic duct with a percutaneous transhepatic cholangial drainage (PTCD) catheter, a recurrent biliary adenomatosis was diagnosed by cholangioscopy. As there was no surgical option left, the patient received photodynamic therapy (PDT) for the recurrent biliary papillomatosis. Three mo after he received further photodynamic therapies, the bile duct epithelium appeared normal and the patient had no signs of adenomatosis, both macroscopically and histologically. The follow-up cholangioscopy in late 2005 revealed only a small papilloma without the need for intervention. In early 2006, the patient died of multi organ failure without signs of extrahepatic cholestasis or cholangitis at the age of 75, 10 years after the diagnosis of biliary papillomatosis was established. The patient exceeded the average life expectancy of patients with biliary papillomatosis by far. Thus, PDT might be a sufficient therapeutic option for recurrent papillomatosis patients with no significant side effects.

Surgical treatment of malignant biliary papillomatosis invading adjacent organs: A case report

BACKGROUND

Biliary papillomatosis (BP) is a rare disease characterized by multiple papillary adenomas in the intrahepatic and extrahepatic biliary tree and has a high risk of malignant transformation. Early diagnosis and treatment for BP are challenges, as it spreads along the biliary tract. A radical resection with an adequate resection margin is advocated in patients with malignant BP.

CASE SUMMARY

We report a case of BP with malignant transformation in a 52-year-old female patient who presented with emaciation, severe malnutrition, and a T-tube for biliary drainage that was placed for almost 2 years at the time she visited us. The enhanced magnetic resonance imaging of the upper abdomen revealed a neoplasm with a diameter of 15 cm located in the gallbladder area surrounding the common bile duct where a drainage tube was placed. It was the first case with malignant BP involving multiple organs and the abdominal wall and receiving a radical resection. Plastic surgeons helped close the incision by transferring the rectus muscle and external oblique muscle flap. A diagnosis of papillary carcinoma with diffuse malignant papillomatosis of the biliary duct was given. The postoperative course was uneventful and she was asymptomatic and in good physical condition at 35 mo postoperatively with appropriate chemotherapy.

CONCLUSION

Aggressive surgical treatment with appropriate chemotherapy is advocated for patients with malignant BP even if multiple organ invasion is present.

Successful cholangioscopic electrocoagulation for biliary papillomatosis: Report covering six cases (with video)

BACKGROUND

Biliary papillomatosis is a rare type of papillomatosis. Depending on the location of the disease, radical surgical resection or liver transplants are the treatment of choice. These radical surgical options may be unrealistic in patients who are not surgical candidates or who are unwilling to consider surgery.

AIMS

To evaluate the effectiveness of endoscopic electrocoagulation for the biliary papillomatosis.

METHODS

In this case series, we report six patients with unresectable biliary papillomatosis who underwent cholangioscopic electrocoagulation using needle knife and their clinic follow up information.

RESULTS

After patients received cholangioscopy with electrocoagulation of the residual biliary papilloma, the daily T-tube drainage volume increased to 200-400ml with improvement in the drainage content and significant relief of clinical symptoms, such as jaundice and abdominal pain.

CONCLUSION

This method of using electrocoagulation to directly target and destroy tumor tissue is a safe and effective alternative for those with unresectable disease, and this method has shown to enhance T-tube drainage volume and improve patients' overall clinical symptoms.

Unusual presentation of gallbladder papillomatosis without bile duct involvement: A case report

The papillomatosis is a very rare benign pathology diagnosed histologically with a significant potential for malignant transformation. We report a case a 60-year-old female without comorbidity present the gallbladder papillomatosis without involvement of the intra or extra hepatic biliary tract. The interest in knowing the radiological aspect of this pathology and make the early diagnosis in order to oriented treatment.

Intrahepatic biliary papillomatosis associated with malignant transformation: report of two cases and review of the literature

Biliary papillomatosis (BP) is a rare disease characterized by multiple numerous papillary adenomas in both the intrahepatic and extrahepatic biliary tree. Due to its high recurrence rate and frequent transformation to malignancy, BP should not be considered a benign disease, and a radical resection with an adequate resection margin is advocated in cases of localized intrahepatic biliary papillomatosis. Since BP is a rare disease and its clinical features and outcomes are not well known, it's really difficult to diagnose the disease before operation. We encountered two cases diagnosed as intrahepatic biliary papillomatosis postoperatively, and herein present the diagnostic difficulties and therapeutic options for this rare disease.

Intraductal Papillary Neoplasm of the Bile Duct: Radiological Diagnosis of a Rare Entity: Case Series

Background

Intraductal papillary neoplasm of the bile duct (IPNB) is a rare bile duct neoplasm characterized by an intraluminal papillary growth pattern in bile ducts and is considered a biliary counterpart of intraductal papillary mucinous neoplasm of the pancreas.

Case description

We report here two cases. (1) A case of a 34-year-old woman who presented with complaints of pain in the abdomen, jaundice, and pruritus. Further radiological investigations revealed the possibility of an IPNB, which was confirmed on histopathology. (2) A case of a 61-year-old man who was a known case of Barrett's esophagus and presented with complaints of right upper abdomen and jaundice. Radiological investigations and histopathology further confirmed the diagnosis of an IPNB involving the extrahepatic bile ducts. The purpose of this article is to highlight the role of computed tomography (CT) and magnetic resonance imaging in reaching this challenging diagnosis.

Conclusion

Although the diagnosis is not straightforward, imaging plays a great role in raising the possibility of an IPNB. The correct preoperative diagnosis is necessary for accurate surgical planning and resection.

Living donor liver transplantation for diffuse biliary papillomatosis with malignant change: A case report with 10-year follow-up

Biliary papillomatosis is a rare disease of the biliary tract. In this study, we present a case of a male patient with biliary papillomatosis with malignant change who underwent living donor liver transplantation (LDLT). The 49-year-old man was admitted due to intrahepatic ductal mass, which was finally diagnosed as biliary papillomatosis. It was initially treated by photodynamic therapy, but LDLT was planned due to low efficacy of photodynamic therapy. LDLT was performed with a right liver graft from his son. The pathology report revealed intraductal papillary neoplasm with associated invasive carcinoma. He recovered uneventfully. Although the distal bile duct resection margin was free of tumor, the risk of tumor recurrence at the remnant intrahepatic bile duct still remained. Therefore, staged pylorus-preserving pancreatoduodenectomy was planned. However, after 3 months, he was readmitted due to retropancreatic abscess. It took 6 months to control the intractable retropancreatic abscess. Due to late development of retropancreatic abscess and its slow recovery, staged pancreatoduodenectomy was no longer considered. The patient recovered complete at 1 year posttransplant without any evidence of disease recurrence. After 5 years posttransplant, lung metastasis developed and pulmonary metastasectomy was performed three times. No further recurrence developed during the last 3 years to date, and the patient currently is alive, 10 years after the LDLT. Experience on our case and literature review suggest that patients with biliary papillomatosis with or without malignant transformation are selectively indicated for liver transplantation.

Biliary papillomatosis

Biliary papillomatosis (BP) is a rare disorder of the biliary tract characterized by the presence of multiple papillary adenomas spread along the biliary tree. Although benign, it carries a significant risk of malignant transformation. Due to low sensitivity and specificity of conventional radiologic modalities, the diagnosis as well as estimation of disease extent is difficult. Endoscopic ultrasound (EUS) and endoscopic retrograde cholangiopancreaticography (ERCP) are superior although direct peroral cholangioscopy (POC) is currently the most accurate diagnostic method. Mainly because it provides more detailed information and makes targeted histological diagnosis possible. The treatment of biliary papillomatosis consists of surgical resection, liver transplantation (LT) or a combination of both. Unfortunately, the recurrence rate after radical surgery without LT remains high due to the diffuse distribution of the disease.
