1. In 46 cases, the third porta hepatis was isolated.

2. Objective:To investigate if freezing of the first porta hepatis can lead biliary duct impairment and change hepatic hemodynamics.

3. We also can treat the porta hepatis tubing of the operation area and protect the portal vein before resection.

4. Normothetic occlusion of porta hepatis can reduce blood loss effectively when liver resection.

5. Theof ductal proliferation and liver cirrhosis around porta hepatis differed among theof different age groups.http://

6. A good surgical exposure of porta hepatis in 81 patients with various hepatobiliary diseases was gained with the technique of sharp dissection and electronic coagulation.

7. Objective To summarize the clinical experiences on diagnosis and treatment of hepatolithiasis accompanied with bile stricture near porta hepatis.

8. Objective : To discuss the pathogenesis and the treatment of the benign stricture of the bile duct in porta hepatis.

9. The quadrate lobectomy is an effective mean of treating patients with hepatolithiasis accompanied with bile stricture near porta hepatis.

10. Two-stage operation is only indicated for unresectable PLC but not for large tumors involved the porta hepatis or IVC. The resectability should be judged carefully.

11. CONCLUSION: The malignant disease is the main cause of bile duct stricture in porta hepatis. Meanwhile, imaging techniques can help to make accurate diagnosis of this disease.

12. AIM: To summarize the causes of bile duct stricture in porta hepatis and probe into the diagnostic values of imaging techniques.

13. Conclusion (1) MRCP is the best technique in the diagnosis of hepatolithiasis accompanied with bile stricture near porta hepatis.

14. The pathologic changing of BA is the key to its pathogenesis and prognosis. It is probable that the whole pathologic changing is derived from the porta hepatis.

15. Objective To discuss the surgical therapeutic approach to medium-term and advanced bile duct carcinoma in porta hepatis.

16. Objective: To investigate the relationship between approaches and their efficacy for surgical treatment of hepatolithiasis accompanied with bile stricture near porta hepatis.

17. Objective To discuss the surgical therapeutic approach medium - term and advanced bile duct carcinoma in porta hepatis.

18. Conclusion If direct profound hypothermia was performed in the first porta hepatis, it should pay attention to avoid the injury of the biliary system.

19. The perfect protection of biliary system should be accomplished in the cryosurgery of the first porta hepatis to avoid severe complications.

20. Objective To investigate the CT features and pathologic basis of cholangiocarcinoma in porta hepatis.
