Aim: To determine the clinical, radiographic and pathologic characteristics, diagnostic and treatment modalities in patients with autoimmune pancreatitis (AIP).

Methods: In this retrospective study, the data of patients with diagnosed chronic pancreatitis (CP) between 1995 and 2006 in Chinese PLA General Hospital were included to screen for the cases with AIP, according to the following diagnostic criteria: (1) diagnostic histopathologic features, and abound IgG4-positive plasma cells on pancreatic tissues; (2) characteristic imaging on computed tomography and pancreatography, together with increased serum IgG, gamma-globulin levels or presence of autoantibodies; (3) response to steroid therapy. The clinical, radiographic and pathologic characteristics, diagnostic and treatment modalities, and outcome of AIP cases were reviewed.

Interventional treatment of acute hepatic artery occlusion after liver transplantation.

Background: With the development of the associated technology, interventional treatment has become an important method for the treatment of hepatic artery occlusion in some countries. This study was undertaken to evaluate the role of interventional methods in the diagnosis and treatment of acute hepatic artery occlusion after liver transplantation.

Methods: The diagnosis and treatment of 9 cases of acute hepatic artery occlusion after liver transplantation were retrospectively analyzed.

[Surgical treatment of 402 consecutive cases for hilar cholangiocarcinoma: Chinese single center experience].

Objective: To analyze clinical typing, pathologic characteristics of hilar cholangiocarcinoma (HCCA) and surgical strategies and their effects on HCCA, and to explore the factors that influence the surgical outcomes and long-term survival.

Methods: The data of the 402 patients with HCCA admitted between January 1993 and December 2004 was investigated retrospectively. Primary outcomes examined included clinical typing, pathologic characteristics, surgical procedures and follow-up results.

[Interventional radiological techniques in management of early hepatic artery thrombosis after liver transplantation].

Objective: To evaluate the safety and efficacy of interventional radiological techniques in management of early hepatic artery thrombosis (HAT) after orthotopic liver transplantation (OLT).

Methods: Nine patients with HAT after OLT, 8 males and 1 female, aged 47.6 (32-63), presenting elevation of liver enzymes and bilirubin, whose diagnosis was suggested by Doppler ultrasonography and confirmed by angiography 16 hours to 10 days after the OLT, underwent interventional radiological techniques, including indwelling transcatheter hepatic artery (HA) thrombolysis with a low dose of urokinase, and stent placement into the stenotic segment of HA.

[Experience of diagnosis and treatment of carcinoma arising from congenital biliary duct cyst].

Objective: To summarize the experience in diagnosis, prevention and treatment of carcinoma arising from congenital biliary duct cyst.

Methods: The clinical and pathological data of 185 patients with congenital biliary duct cyst admitted to Chinese PLA General Hospital were analyzed retrospectively.

Results: Among 185 patients, twenty-seven cases had carcinomas arising from congenital biliary duct cyst, and the frequency of malignant transformation was 14.

[Radiofrequency ablation for hypersplenism due to portal hypertension: clinical study].

Objective: To investigate the feasibility, efficacy and clinical prospects of radiofrequency ablation (RFA) for hypersplenism in patients with liver cirrhosis and portal hypertension.

Methods: The laboratory and radiologic data over one-year period of patients undergone splenic RFA were analyzed.

Results: Nine patients undergone splenic RFA has closely followed-up over 1 year.

Diagnosis and management of regional portal hypertension.

Objective: Regional portal hypertension (RPH) results from splenic vein thrombosis/occlusion, with emergence of gastric varices and severe upper gastrointestinal bleeding. Its diagnosis and management are summarized below.

Methods: We reviewed our experience in 16 consecutive patients with RPH at Chinese PLA General Hospital between 2001 and 2004.

[Operational line of laparoscopic liver resections].

Objective: To evaluate the feasibility and indications of laparoscopic liver resections.

Methods: Twenty-seven patients with liver lesions, 17 men and 10 women, aged 31 - 67, including 14 cases of primary liver cancer, 6 cases of liver hemangioma, 2 cases of liver abscess, 1 case of hilar carcinoma, 1 case of hepatic adenoma, 1 case of hepatic focal nodular hyperplasia, 1 case of liver inflammatory granuloma, and 1 case of infected liver cyst, underwent laparoscopic liver resection, partial liver resection in 17 cases and anatomical left liver resections in 10 cases, consecutively from July 2002 to April 2003. The clinical data were analyzed.

Protective effects of lidocaine injected into the hepatoduodenal ligament on warm ischemia-reperfusion injury to the rat liver.

Background: Ischemia-reperfusion (IR) injury to the liver is still a critical and daunting problem in the field of hepatobiliary surgery. Ischemic preconditioning (IP) of the liver serves as an effective approach against IR injury. This study was to develop a novel procedure that could mimic IP, but might be more feasible than IP during surgery.
