This study aims to compare the early outcomes between pure laparoscopic living donor right hepatectomy (PLDRH) and open living donor right hepatectomy (ODRH) after those learning curve. Our analysis was based on 78 consecutive cases of living liver donor, who underwent right hepatectomy, of which 43 underwent ODRH and 35 PLDRH. The learning curve for each group was analyzed. Donor characteristics were comparable between the two groups. Two donors in the PLDRH required conversion to an open due t

The complexity classification outperformed the major/minor classification for predicting the surgical difficulty of liver resection.

This paper presents a novel framework to extract highly compact and discriminative features for face video retrieval tasks using the deep convolutional neural network (CNN). The face video retrieval task is to find the videos containing the face of a specific person from a database with a face image or a face video of the same person as a query. A key challenge is to extract discriminative features with small storage space from face videos with large intra-class variations caused by different an

This study reports our experience using deceased donor liver grafts from HBsAg-positive donors. We performed eight cases of liver transplantation (LT) using grafts from deceased HBsAg-positive donors between November 2005 and October 2010. The median age of donors was 48 years (range: 26-64). HBV DNA in the serum of donors ranged from 44 to 395 IU/ml, but HBeAg in all donors was negative. Preoperative laboratory and liver biopsy samples revealed the absence of definitive cirrhotic features and h

Living donor hepatectomy is now a well-established surgical procedure. However, a large abdominal incision is still required, which results in a large permanent scar, especially for a right liver graft. This report reviews our techniques of minimally invasive or minimal incisional donor hepatectomy using a transverse incision.Twenty-five living donors underwent right hepatectomy with a transverse incision and 484 donors with a conventional incision between April 2007 and December 2012. Among the

Purpose: We evaluated the heterogeneity of steatosis in living donor livers to determine its regional differences. Methods: Between June 2011 and February 2012, 81 liver donors were selected. Fat fraction was estimated using magnetic resonance triple-echo chemical shifting gradient imaging in 13 different regions: segment 1 (S1), S2, S3, and each peripheral and deep region of S4, S5, S6, S7, and S8. Results: There were differences (range, 3.2%-5.3%) in fat fractions between each peripheral and d

Overcoming the learning curve of LMH before starting TLDRH is advisable to ensure donor's surgical outcomes.

The remnant liver volume, its function and tumor clearance are important issues in laparoscopic liver resection (LLR). With increasing knowledge of LLR, surgical safety and oncological results after LLR are now similar to those after open liver resection. Anatomical LLR has emerged from the introduction of the Glissonean pedicle approach to open surgery. When anatomical LLR is performed with this approach, many types of resections are possible, including major resections, bisegmentectomy, and mo

Background The aim of this study was to investigate the current status and identify any existing problems in the allocation system of liver transplantation (LT) for children in Korea. Methods The information for the period between January 2006 and March 2012 contained in the Korean Network for Organ Sharing (KONOS) database, and the 2008 and 2010 annual reports from KONOS were analyzed. Detailed information about split LT (SLT) was analyzed using the SLT database which contains data collected si

Solo SILLR is more feasible and safer for liver tumours located in the superficial right liver or in the left one. Therefore, solo surgery can be an option in SILLR.

Surgery yielded greater growth improvement than dietary management. However, after PCS, metabolic abnormalities remained unresolved, and the de novo HCA rate was high. Portacaval shunting can be used to improve growth in GSD type I patients when LT is not possible, but close observation for metabolic abnormalities and HCA is essential.

From our initial experience, RH might be considered as a feasible procedure in the liver resection, even in major hepatectomy. In addition, surgeons with sufficient experience in LH could rapidly adapt for RH. However, we have to make a system for education and monitoring of this innovative surgery for the patients' safety.
