BACKGROUND Laparoscopic liver resection is an attractive option for treating liver tumors. Laparoscopic liver resection is more difficult for hepatocellular carcinomas located in the posterosuperior segments than for hepatocellular carcinomas in the anterolateral segments. We compared perioperative and long-term outcomes between laparoscopic liver resection(More)
A classification system for defining the complexity of hepatectomy according to its technical difficulty was recently proposed as a consensus of a panel of experts. We validated this classification system for a prospective liver resection cohort in patients with hepatocellular carcinoma (HCC). The complexity classification separated liver resections into(More)
A difficulty scoring system (DSS) based on the extent of liver resection, tumor location, liver function, tumor size, and tumor proximity to major vessels was recently developed to assess the difficulty of various laparoscopic liver resection procedures. We validated DSS in patients who underwent laparoscopic left lateral sectionectomy (LLS). We reviewed(More)
The optimal surgical strategy for treating colorectal cancer liver metastases (CRLM) in patients requiring major liver resection (MLR) is controversial, especially in rectal cancer patients. Between March 2004 and January 2015, 103 patients underwent MLR for CRLM and underwent MLR simultaneously with colorectal surgery (simultaneous group; n = 55) or MLR(More)
BACKGROUND Laparoscopic left lateral sectionectomy (LLS) is now considered as a standard practice. However, the safety of laparoscopic LLS in cirrhotic patients is unclear. This is the retrospective study of comparing the outcomes of laparoscopic LLS between cirrhotic and non-cirrhotic patients. METHODS We reviewed the clinical data for 107 patients who(More)
PURPOSE In Korea, the entire population must enroll in the national health insurance system, and those who are classified as having a lower socioeconomic status are supported by the medical aid system. The aim of this study was to evaluate the association of the medical insurance status of gastric cancer patients with their survival after gastrectomy. (More)
In this paper, we propose a channel prediction-based user selection algorithm for a single-cell wireless network with multiuser environments. The proposed algorithm focuses on mitigating the degradation of performance due to a feedback process. In particular, by using the Naive Bayes (NB) classifier, the proposed algorithm selects the user who is expected(More)
BACKGROUND Caudate lobe is located in the deep dorsal area of the liver between the portal triad and the inferior vena cava (IVC). Torrential bleeding can occur from the IVC and short hepatic veins during dissection. Isolated total caudate lobe resection is still rare and technically demanding. We herein present a video on the technical aspect of(More)
BACKGROUND When hepatocellular carcinoma (HCC) was located in segment 2 (S2), segment-oriented hepatectomy was more beneficial than left lateral sectionectomy as this type of anatomical resection preserved the volume of the nontumor-bearing segment. Herein, we presented 2 cases (1 with video) of laparoscopic anatomical S2 segmentectomy by the Glissonian(More)
OBJECTIVE To compare performances for predicting surgical difficulty and postoperative complications. BACKGROUND An expert panel recently proposed a complexity classification for liver resection with 3 categories of complexity (low, medium, or high). We compared this new classification with the conventional major/minor classification. METHODS We(More)
