Combined hepatocellular carcinoma (HCC) and cholangiocarcinoma (CC) is sometimes found in resected livers, however, cases with double cancer of HCC and CC are very rare. As well, the rarity of CC arising in von Meyenburg complexes (VMCs) is appreciated. We report the case of a 74-year-old man found to have intrahepatic double cancer composed of well-differentiated HCC and CC which exhibited a histologic progression from VMCs to adenomatous lesions and CC. To our knowledge, this is the first case report published in the literature of a double HCC and CC associated with multiple VMCs. The pathogenesis and previous associated reports of these lesions are discussed.

Portal vein embolization (PVE) is known as an effective and safe preoperative procedure that increases the future liver remnant (FLR) in patients with insufficient FLR. However, some possible major complications can lead to non-resectability or delayed elective surgery that results in increased morbidity and mortality. Although the majority of these complications are rare, knowledge of the radiologic findings of post-procedural complications facilitate an accurate diagnosis and ensure prompt management. We accordingly reviewed the CT findings of the complications of PVE.

Biliary drainage in patients with malignant biliary obstruction relieves jaundice and prevents the development of cholangitis or hepatic failure from biliary obstruction. Therefore, this may result in better quality of life along with survival prolongation. Biliary stent placement is an effective and safe measure for biliary decompression and is preferred than bypass surgery in high risk patients. Entero-biliary perforation-communication is one of the rare complications of biliary stent. We herein report a case of duodeno-biliary perforation-communication in patient with distal cholangiocarcinoma who presented with duodenal ulcer and obstruction, occurring 4 years later from the metallic biliary stent insertion. Patient was managed with a pyloric metal stent and conservative care.

OBJECTIVETo evaluate the down stream involvement of the bile duct in hepatolithiasis.

METHODSMechanical damage to bile duct epithelia and long standing cholangitis as result of hepatolithiasis play an important role in the carcinogenesis of bile duct epithelia and stricture of the intra- and extra-hepatic bile duct. Macromorphological and microscopic changes in bile duct mucosa of 100 consecutive patients with hepatolithiasis were investigated using intra- or post-operative cholangioscopy. Biopsy specimens of lesions obtained during cholangioscopy were studied with immunohistochemical staining and flow cytometry to determine proliferative activity and DNA content. Five cases of well-proven cholangiocarcinoma were simultaneously studied as controls.

RESULTSOf the 100 patients, those with chronic cholangitis accounted for 86% (86/100), proliferative lesions 11% (11/100), adenomatous polyps 1% (1/100), and adenocarcinoma 2% (2/100). The obvious mucosal lesion associated with hepatolithiasis was located down-stream of the bile duct, predominantly in the hilar region, e.g. orifices of the right/left hepatic duct and common hepatic duct (73% mucosa lesions in the hilar region). The intensity of cancer embryonic antigen stain and the proliferative cell nuclear antigen index increased with the development of bile duct lesions. Aneuploid DNA presented mainly in the high degree malignant adenocarcinomas (> 80% of cases).

CONCLUSIONSThe obvious mucosal lesions associated with hepatolithiasis were located down-stream of the bile duct, predominantly in the hilar region (73% of mucosal lesions). The proliferative activity of examined bile duct mucosa lesions increased with the development of pathological deterioration, which may contribute to the development of hilar bile duct stricture and hilar cholangiocarcinoma.

OBJECTIVE To study the correlation between hepatic hilar cholangiocarcinoma and the infection of HB (C)V. METHODS Combined with clinical data, immunohistochemistry was used to detect HBXAg antigen and HCV-C protein in 68 formalin-fixed and paraffin-embedded samples of hilar cholangiocarcinoma. RESULTS Six cases(8.8%) were positive to HBXAg antigen and 24 cases (35.0%) to HCV-C protein respectively. One case was positive to both HBXAg antigen and HCV-C protein. There were statistical differences in differentiation and invasion, lymph node metastasis, treatment between hilar cholangiocarcinomas infected HB(C)V and those non-infected. CONCLUSIONS HBXAg antigen and HCV-C protein may play an important role in the pathogenesis of hilar cholangiocarcinoma. Hilar cholangiocarcinoma infected HB(C)V may have a high malignancy and more poor prognosis.

Anomalous union of the pancreaticobiliary duct (AUPBD) is a congenital anomaly that is defined as a junction of the bile duct and pancreatic duct outside the duodenal wall. This anomaly results in a loss of normal sphincteric mechanisms at the pancreaticobiliary junction. As a result, regurgitation of pancreatic juice into the biliary system develops and causes choledochal cysts, choledocholithiasis, cholangitis, pancreatitis and malignancy of the biliary tract. Gallbladder cancer or common bile duct cancer associated with AUPBD and choledochal cysts have been frequently reported. But, intrahepatic cholangiocarcinoma associated with this condition has been only rarely reported. Here, we report a case of intrahepatic cholangiocarcinoma associated with AUPBD and choledochal cyst.

OBJECTIVETo evaluate the surgical technique of "Kou mode of hepatic hilar anastomosis" in the treatment for type III or IV hilar cholangiocarcinoma.

METHODSThe clinical data of 89 patients with type III or IV hilar cholangiocarcinoma surgically treated in our department between Jan. 1990 and Jan. 2008 were retrospectively analyzed. Since January 2000, "Kou mode of hepatic hilar anastomosis" was performed for some patients with advanced hilar cholangiocarcinoma. The patients were divided into two groups: group A treated between 1990 and 1999, group B between 2000 and 2008. The rate of resection, therapeutic efficacy and complications in these two groups were compared, respectively.

RESULTSOf the 37 cases with hilar cholangiocarcinoma in group A, 4 were surgically treated (10.8%), with 1 (2.7%) radical resection and 3 (8.1%) palliative resection. Among the 52 cases with hilar cholangiocarcinoma in the group B, 35 (67.3%) received surgical resection, of them 15 (28.8%) underwent radical resection and 20 (38.5%) had palliative resection. Twenty-eight of these 35 cases underwent the "Kou mode of hepatic hilar anastomosis". The resection rate of advanced hilar cholangiocarcinoma in the group B was significantly higher than that in group A (P < 0.05). The complications in the 89 cases included ascites (3 cases), hemobilia (1 case), heart failure (1 case), and wound infection (2 cases). All the patients who were treated with the "Kou mode of hepatic hilar anastomosis" developed bile leakage to a varying degree and recovered after drainage and symptomatic treatment.

CONCLUSIONThe resection rate of type III or IV advanced hilar cholangiocarcinoma can be remarkably improved by using a novel alternative surgical technique called "Kou mode of hepatic hilar anastomosis". However, the long-term outcome still needs to be determined by close follow-up and further observation.
