Laparoscope Anatomical and Aon-anatomical Hepatectomy
Study Details
Study Description
Brief Summary
The purpose of this study is to compare short-term and long-term efficacy of two surgical methods by laparoscopic hepatectomy, and provide the evidence for the choice of surgical method from the pathology and cytology.

Detailed Description
Background:Hepatocellular carcinoma is the world's most common and most malignant tumor, accounting for more than 90% of primary liver cancer, the incidence ranked fifth of malignant tumors in the world. surgery and comprehensive treatment is recognized by the medical profession Surgical approach, including the open HCC hepatectomy and laparoscopic hepatectomy, minimally invasive surgery is the main theme of the 21st century, and laparoscopy as the one of the elements in the field of minimally invasive surgery which carried out more and more in liver surgery, but which one of the two methods to choice to hepatectomy lack of sufficient scientific evidence.The RCT research of laparoscopic anatomical and non-anatomical hepatectomy for HCC has not been reported at home and abroad; Intervention:We let the 110 patients divide into A, B groups randomly who are meet the inclusion criteria .Group A is Laparoscopic Anatomical Hepatectomy: Anatomy the corresponding liver segment pedicle and hepatectomy along the Glisson fiber sheath.Group B is Laparoscopic Aon-anatomical Hepatectomy:1 to 2 cm along the edge of the tumor complete hepatectomy
Results:
-
operation time, intraoperative blood loss, rate of blood transfusion, complications and mortality, postoperative liver function, resection margin, number of micrometastases ,long-term curative effect and survival time were collected and analysed.
-
groups t-test ，univariate/multivariate analysis, logistic regression analysis, mixed linear regression, Cox survival analysis ，Kaplan-Meier survival analysis，Log-rank survival curves were used.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Laparoscop Anatomical Hepatectomy Total laparoscopic anatomical hepatectomy were performed, combined with cholecystectomy when necessary. The intraoperative ultrasound, hepatic segmental staining were used selectively. |
Procedure: Laparoscopic Anatomical Hepatectomy
We let the 110 patients divide into A, B groups randomly who are meet the inclusion criteria .Group A is Laparoscopic Anatomical Hepatectomy: Anatomy the corresponding liver segment pedicle and hepatectomy along the Glisson fiber sheath
|
| Active Comparator: Laparoscope Aon-anatomical Hepatectomy Total laparoscopic aon-anatomical hepatectomy were performed, combined with cholecystectomy when necessary. The intraoperative ultrasound or hepatic segmental staining will be used to ensure the tumour was completely resected. |
Procedure: Laparoscopic Aon-anatomical Hepatectomy
We let the 110 patients divide into A, B groups randomly who are meet the inclusion criteria .Group B is Laparoscopic Aon-anatomical Hepatectomy:1 to 2 cm along the edge of the tumor complete hepatectomy
