Brief Summary

Due to many vascular branches on the supra-hepatic vena cava (SHVC) and infra-hepatic vena cava (IHVC), in the whole procedures of preparation of liver donation, preparation of hepatic vena cava (HVC) is the most key and troublesome step. Magnetic Spiderman (MS) is a novel surgical instrument, designed and created to solve the vital problems of preparation of liver donation's HVC. Therefore, the aim of this study is to evaluate the feasibility and security of MS when using it prepare the liver donation's HVC.

Outcome Measures

Primary Outcomes (5)

  • The number of damaged points on HVC

    the number of damaged points on the HVC during the preparation

    measured at the time of the end of preparation HVC; up to 1 hour

  • Operation time

    operation time of preparation of HVC

    measured at the time of the end of preparation HVC; up to 1 hour

  • The number of assistants

    the number of assistants ensuring smooth operation according to attending's requirement

    measured at the time of the end of preparation HVC; up to 1 hour

  • Leak test

    we use nondestructive vascular forceps to occlude the SHVC and IHVC, and perfused about 100 ml organ preservation solution through portal vein. If HVC and portal vein bulge and does not leak, the leak test is negative. Otherwise, it is positive.

    measured at the time of the end of preparation HVC; up to 1 hour

  • HVC hemorrhage

    Whether HVC hemorrhage after implantation

    measured at the time of liver implanted to the recipient; up to 1 hour

Secondary Outcomes (1)

  • Frequency of MS's detachment

    measured at the time of the end of preparation HVC; up to 1 hour

Study Arms (2)

MS group

EXPERIMENTAL

In the MS group, the MS grips the HVC through the magnet adsorbed onto the wall of the basin containing the liver. By changing the position of the MS on the wall of the basin, the surgeon is able to expose the surgical field.

Device: MS

MA group

NO INTERVENTION

In MA group, assistants use vessel forceps to pull the HVC according to the attending's requirements.

Interventions

MSDEVICE

Magnetic Spiderman (MS) is a novel surgical instrumentIt. It consists of a circular neodymium iron boron magnet packed in a stainless-steel case with a spring and a jagged clamp, which gives it a spider-like appearance.

MS group
