Abstract
Abstract
Objective
To explore the clinical application of a newly developed magnetic anchoring traction (MAT) system in the liver bench trimming and transplantation surgery.
Background
The conventionally limited space, vision, and exposure have always been a challenge for the quality of surgery in the liver bench trimming due to the fact that the exposure depends largely on the experience of surgeon. To deal with this problem, a MAT system is developed as an alternative support to enhance exposure. The preliminarily experiments on animals verified its feasibility and reliability in the practical use, and its clinical application and effects were examined in the present research.
Methods
A total of 20 DCD (donation of cardiac death) donor livers were collected and divided evenly between the magnetic anchor traction (MAT) assisted group (n = 10) and the manual assisted group (n = 10). The results and quality assessment from experts about the liver bench surgery performed by two groups were examined and compared.
Results
The MAT system can be employed effectively to compete and replace the manual assistance to achieve a better exposure in the liver bench trimming. No statistical difference was found regarding the baseline data between the MAT and the manual groups. In the inferior vena cava and hepatic artery trimming, the MAT group outperformed the manual group remarkably in many aspects. The surgery time for liver bench shortened considerably after a quick grasp of MAT skills by surgeons.
Conclusion
The MAT system provides a more stable, reliable and qualified local exposure in the liver bench surgery, and can preferably be employed to replace the manual assistance in the procedures of liver transplantation.

PLoS One 2016; 11:e0162992. [PMID: 27706183 PMCID: PMC5051740 DOI: 10.1371/journal.pone.0162992] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2016] [Accepted: 08/31/2016] [Indexed: 12/13/2022] Open
Abstract
The aim of this study was to assess whether the case volume of surgeons and hospitals affects the rates of postoperative complications and survival after liver transplantation. This population-based retrospective cohort study included 2938 recipients of liver transplantation performed between 1998 and 2012, enrolled from the Taiwan National Health Insurance Research Database. They were divided into two groups, according to the cumulative case volume of their operating surgeons and the case volume of their hospitals. The duration of intensive care unit stay and post-transplantation hospitalization, postoperative complications, and mortality were analyzed. The results showed that, in the low and high case volume surgeons groups, respectively, acute renal failure occurred at the rate of 14.11% and 5.86% (p<0.0001), and the overall mortality rates were 19.61% and 12.44% (p<0.0001). In the low and high case volume hospital groups, respectively, acute renal failure occurred in 11% and 7.11% of the recipients (p = 0.0004), and the overall mortality was 18.44% and 12.86% (p<0.0001). These findings suggest that liver transplantation recipients operated on higher case volume surgeons or in higher case volume hospitals have a lower rate of acute renal failure and mortality.
