The oncologic safety and feasibility of laparoscopic D2 gastrectomy for advanced gastric cancer are still uncertain. The aim of this study is to compare our results for laparoscopic D2 gastrectomy with those for open D2 gastrectomy. Between 1998 and 2008, a total of 336 patients with clinical T2, T3, or T4 tumors underwent laparoscopic (n = 186) or open (n(More)
OBJECTIVE To evaluate the comparative safety and efficacy of robotic vs laparoscopic gastrectomy for early-stage gastric cancer. DESIGN Retrospective analysis. SETTING Tertiary hospital. PATIENTS Eight hundred twenty-seven patients with gastric cancer. INTERVENTIONS Between July 2005 and April 2009, 827 patients with gastric cancer underwent 236(More)
Meticulous mediastinal lymphadenectomy frequently induces recurrent laryngeal nerve palsy (RLNP). Surgical robots with impressive dexterity and precise dissection skills have been developed to help surgeons perform operations. The objective of this study was to determine the impact on short-term outcomes of robot-assisted thoracoscopic radical esophagectomy(More)
D2 total gastrectomy combined with splenectomy or pancreaticosplenectomy reportedly increases morbidity and mortality. Totally laparoscopic total gastrectomy (TLTG) for advanced gastric cancer (AGC) remains controversial because of its technical difficulties and lack of long-term results. We determined the feasibility and safety of TLTG for AGC. A(More)
Suprapancreatic lymph node (LN) dissection is critical for gastric cancer surgery. Until currently, a number of laparoscopic gastrectomy procedures have been performed in the same manner as open surgery procedures [3, 4, 6]. Using the characteristic of laparoscopic surgery, the authors developed a new technique of suprapancreatic LN dissection. After(More)
Robotic gastrectomy (RG) for gastric cancer (GC) has been increasingly performed over the last decade. The technical feasibility and safety of RG for GC, predominantly early GC, have previously been reported; however, few studies have evaluated the oncological outcomes. This study aimed to determine the long-term outcomes of RG for GC compared with those of(More)
Robotic surgery with the da Vinci Surgical System has been increasingly applied in a wide range of surgical specialties, especially in urology and gynecology. However, in the field of upper gastrointestinal (GI) tract, the da Vinci Surgical System has yet to be standard as a result of a lack of clear benefits in comparison with conventional minimally(More)
In patients having locally advanced cancer of the stomach with suspected tumor infiltration to the pancreatic head or the duodenum, a concurrent pancreaticoduodenectomy with gastrectomy is occasionally prerequisite to achieve a microscopically tumor-free surgical margin. We present the first series of successful totally laparoscopic pancreaticoduodenectomy(More)
Orotate phosphoribosyltransferase (OPRT; EC, a key enzyme that catalyzes one of the primary steps in the phosphorylation of fluoropyrimidine, was recently recognized as an important enzyme that determines the anticancer effects of the dihydropyrimidine dehydrogenase-inhibitory fluoropyrimidine, S-1. Levels of OPRT were examined in 97 gastric(More)
