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)
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)
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 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)
Minimal invasive surgery is growing rapidly in vast fields of abdominal surgery. Nowadays, due to the development of laparoscopic instruments and improvement of surgical technique, laparoscopic pancreas surgery is becoming more widely adopted. Laparoscopic distal pancreatectomy has now become a standard procedure for the benign or borderline malignant tumor(More)
Importance The remnant liver after hepatectomy may have inadequate blood supply, especially following nonanatomical resection or vascular damage. Objective To evaluate whether remnant liver ischemia (RLI) may have an adverse effect on long-term survival and morbidity after liver resection in patients with hepatocellular carcinoma. Design, Setting, and(More)
Many centers consider hepatocellular carcinoma (HCC) located in segments 7 or 8 to be unsuitable for laparoscopic liver resection (LLR). We evaluated the safety of LLR of HCC in segments 7 or 8 following the introduction of new laparoscopic techniques. This retrospective study included 104 patients who underwent LLR (n = 46) or open liver resection (OLR) (n(More)
PURPOSE T-tube is a major procedure that prevents complication by biliary decompression, but which is accompanied by complications. Therefore, several procedures such as ENBD, PTBD, and antegrade biliary stent have been attempted, but with controversies as to which procedure is superior. Also, there are no standard procedures after laparoscopic CBD(More)
