ABSTRACT
Objective:To explore the characteristics of biliary stricture after liver transplantation (LT) under SpyGlass peroral choledochoscopy and to investigate its treatment value for difficult stricture.Method:A total of 24 patients of biliary stricture after LT at the Department of Hepatobiliary Surgery, the First Affiliated Hospital of Xi'an Jiaotong University underwent SpyGlass examination from January 2019 to December 2020, 15.5 months (2-58 months) after surgery. The characteristics of different types of strictures and the selective guidewire placement results by SpyGlass were recorded and analyzed.Results:Of the 24 patients, 9 were anastomostic strictures (AS) and 15 others were non-anastomostic strictures (NAS). The main characteristic of 5 initial AS patients was scar constriction. Whether treated or not, all of the 15 NAS patients showed evident inflammatory hyperplasia in hilar bile duct under SpyGlass, 80% (12/15) of which were accompanied with intrahepatic biliary stones. The strictures disappeared with mild hyperplasia in 8 patients (4 AS and 4 NAS) whose biliary stents were extracted. Eleven patients (5 AS and 6 NAS) needed guidwire placement under SpyGlass, six (54.5%) of whom succeeded. The successful rate in AS patients was higher than that of NAS (4/5 VS 2/6).Conclusion:The main characteristic of AS is scar constriction and that of NAS is inflammatory hyperplasia. Selective guidewire placement can be achieved by SpyGlass peroral choledochoscopy with a satisfactory successful rate in the difficult AS.
ABSTRACT
A 56-year-old man who had suffered from intermittent right upper quadrant abdominal pain for 6 months and jaundice for 2 months was admitted for evaluation. Endoscopic retrograde cholangio-pancreatography showed filling defect which suggested tumor. Peroral choledo-choscopy was performed which showed polypoid tumor of the common hepatic duct and biopsy reported as papiilary adenocarcinoma. So segmental resection of the bile duct including removal of tumor with Roux-en Y hepaticojejunostomy was performed successfully.

The causes of jaundice in patients with hepatocellular carcinoma are usually attributed to the underlying liver diseases or extensive hepatic destruction by tumor. Obstructive jaundice by the intraluminal tumor fragment of intrahepatic and/or extrahepatic bile duct in hepatocellular carcinoma is exceedingly rare and usually diagnosed by operation or autopsy. Recently, we observed a patient in whom the fragment of tumor from the primary hepatocellular carclnoma obstructed the common hepatic duct, which was confirmed by peroral choledochoscopy. Using peroral choledochoscopy. we could see the mass located at the common hepatic duct and diagnose histologically by cytologic examination of aspirated material of common bile duct. We describe here this rare case with review the literature on primary hepatocellular carcinoma with jaundice caused by biliary obstruction.
