A Case of Biliary Papillomatosis with Cystic Dilatation of Bile Duct / 영남의대학술지

A 61-year-old male who complained of right upper quadrant pain was referred to the authors for evaluation after his computed tomography suggested biliary adenocarcinoma. The lesion consisted of multiple cysts with papillary mass and peri-ampullay mass. The patient underwent an operation due to a clinical suspicion of biliary cystadenocarcinoma, but the pathology confirmed biliary papillomatosis (BP) after diagnosing intrahepatic papillary neoplasm with high-grade dysplasia and invasive adenocarcinoma with papillary neoplasm from the distal common bile duct to the duodenum. BP is a disease characterized by multiple papillary masses. Its cause has yet to be discovered. It commonly manifests as bile duct dilation but rarely as a ductal cystic change. Under computed tomography or magnetic resonance imaging, both the BP and the cystic neoplasm can show bile duct dilation and a papillary mass, which makes their differential diagnosis difficult. A confirmative diagnosis can be made through a pathologic examination. BP is classified as a benign disease that can become malignant and may recur, though rarely. Its treatment of choice is surgical resection. Laser ablation or photodynamic therapy can be used for unresectable lesions. In the case featured in this paper, biliary papillomatosis was difficult to differentiate from cystic adenocarcinoma due to diffusely scattered multiple large cystic lesions in the liver, and it was histologically confirmed to have become malignant with cystic duct dilation after the operation. This case is reported herein with a literature review.

Desempeño del stent plástico para la paliación en la obstrucción biliar maligna proximal versus distal / Comparison of the performance of plastic stents in palliation of proximal and distal malignant biliary obstructions

Objetivo. Comparar el desempeño de los stents plásticos en el tratamiento de las estenosis malignas distal y proximal de la vía biliar. Métodos. Desde enero de 2002 a febrero de 2009 se revisaron retrospectivamente los casos de 70 pacientes (37 hombres y 33 mujeres) con obstrucción biliar maligna no resecable quirúrgicamente y quienes fueron llevados a implantación de stent plástico. Los stents fueron insertados endoscópicamente. Se realizó la colocación por endoscopia de uno o más stents, según criterio del operador durante el procedimiento. Los objetivos principales del estudio fueron evaluar la permeabilidad del stent y la sobrevida del paciente. Resultados. El tiempo mediano de permeabilidad del stent fue de 81 ± 75 días en el grupo de estenosis proximal (grupo 1) y de 130 ± 69 días en el grupo de estenosis distal (grupo 2) (p 0,40, con IC 95% 0,47-1,37). El tiempo de sobrevida promedio fue de 126 días en el grupo 1 y de 159 en el grupo 2. No hubo una diferencia significativa entre los dos grupos. Conclusiones. La implantación de stent plástico es un método paliativo viable para el manejo de la obstrucción biliar maligna irresecable. La sobrevida total y hasta la obstrucción con el uso de stent plástico en pacientes con estenosis distal comparado con la obstrucción proximal no fue significativamente diferente en nuestro estudio.

Aim: To compare the efficacy of plastic stents in the treatment of distal and proximal stricture of biliary tract neoplasm’s. Methods: From January 2002 to February 2009, 70 patients (37 males, 33 females) with non surgically resectable malignant biliary obstruction who received plastic stent implantation were reviewed retrospectively. The stents were inserted by endoscopy. The endoscopist implants one or more stents if he considers this necessary. The end points of the study were stent occlusion and patient death. Results: The mean time of stent patency was 81 ± 75 days in the group of proximal stricture (group 1) and 130 ± 68 days in the group of distal stricture (group 2), (p 0.40, with CI 95% 0.47-1.37). The mean survival time was 126 days in group 1 and 159 days in group 2. There was not a significant difference between the two groups. Conclusion: Plastic stent implantation is a feasible, palliative method for unresectable malignant biliary obstruction. The overall survival and obstruction with the use of plastic stent in patients with distal stenoses compared with proximal obstruction was not significantly different in our study.

Endoscopic Biliary Stenting in Patients with Malignant Biliary Obstruction / 대한소화기내시경학회지

Cholangiocarcinoma has an extremely poor prognosis and the majority of patients have an incurable disease at the time of presentation. These patients should be offered palliative drainage management. The aims of palliation are to prevent cholangitis or bile peritonitis in the course of follow-up or chemotherapy, and to preserve the functional volume of the liver as much as possible. Endoscopic or percutaneous drainage has become increasingly important in the palliative care of patients with unresectable cholangiocarcinoma. Compared to the percutaneous approach, endoscopic biliary stenting is less invasive, more comfortable, and results in a reduced hospital stay. Therefore, endoscopic biliary stenting should be considered the first-line therapy for jaundice palliation in unresectable cholangiocarcinoma.
