OBJECTIVE To evaluate the technical feasibility, effectiveness, and safety of robot-assisted gastrectomy (RAG) with lymphadenectomy, using the da Vinci system through analyses of our initial series of 100 consecutive patients. SUMMARY BACKGROUND DATA The application of robotic surgery was proven to be one of the best cutting-edge technologies for(More)
Recurrence of early gastric cancer (EGC) after curative resection is rare, and the types of EGC that may recur have not been well studied. We attempted to create a system for predicting recurrence of EGC after R0 resection. From January 1987 to April 2005, 2,923 patients with EGC who underwent curative resection were retrospectively studied. Of them, 79(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)
BACKGROUND There has been much controversy surrounding the biologic behavior and prognosis of early stage gastric signet ring cell carcinoma (SRC). To clarify the biologic behavior of early stage gastric SRC (early SRC), we compared the clinicopathologic features and prognosis of early SRC with other histologic types. METHODS A total of 933 patients with(More)
OBJECTIVE Finding the anthropometric measure of visceral obesity is essential to clinical practice, because it predicts cardiovascular and metabolic risks. Sagittal abdominal diameter (SAD) has been proposed as an estimate of visceral adipose tissue (VAT). The aim of the present study was to evaluate the usefulness of SAD in predicting visceral obesity by(More)
OBJECTIVE An optimal treatment strategy for ovarian metastases of gastric cancer has not been clearly established. The aim of this study was to examine the role of a metastasectomy in the management of metachronous Krukenberg tumors after curative surgery for gastric cancer. METHODS Among 1235 female patients who had undergone a curative gastric resection(More)
PURPOSE The purpose of this study was to assess the extent of the increased intracranial pressure (ICP) resulting from CO2 pneumoperitoneum and steep Trendelenburg positioning using ultrasonographic measurement of optic nerve sheath diameter (ONSD) in patients undergoing robot-assisted laparoscopic radical prostatectomy (RALRP). PATIENTS AND METHODS(More)
Heterogeneous survival rates in patients with similar clinicopathologic characteristics or molecular prognostic markers have been noted. This study was conducted to evaluate the prognostic effect of lymphatic and/or blood vessel invasion (LBVI), identified by routine hematoxylin and eosin staining, on the outcome of patients with node-negative advanced(More)
BACKGROUND Gastric signet ring cell carcinoma (SRC) is a histological type based on microscopic characteristics and not on biological behavior. This study compared the clinicopathological features and prognosis of advanced SRC with non-signet ring cell adenocarcinoma (NSRC) of the stomach. METHODS We reviewed the records of 4,759 consecutive patients(More)
