In gastric full-thickness resection employing both endoscopy and laparoscopy, intraabdominal contamination or even possibly tumor seeding is unavoidable as a result of iatrogenic perforation and the resultant spread of gastric juice. To minimize contamination and resected tissue volume, we developed a new technique without perforation termed non-exposed(More)
BACKGROUND The inflammation-based Glasgow prognostic score (GPS) has been shown to be a prognostic factor for a variety of tumours. This study investigates the significance of the modified GPS (mGPS) for the prognosis of patients with gastric cancer. METHODS The mGPS (0=C-reactive protein (CRP) ≤ 10 mg l(-1), 1=CRP>10 mg l(-1) and 2=CRP>10 mg l(-1) and(More)
PURPOSE The aim of this study was to combine clinicopathologic variables associated with overall survival after gastric resection with D2 lymphadenectomy (D2 gastrectomy) for gastric cancer into a prediction nomogram. PATIENTS AND METHODS We retrospectively analyzed 7,954 patients who underwent D2 gastrectomy for gastric cancer at Seoul National(More)
BACKGROUND & AIMS Improving methods for early detection of gastric cancer could reduce mortality. Measurements of serum pepsinogen levels have been used for screening in Japan without satisfactory levels of sensitivity or specificity. Trefoil factor family (TFF) proteins (TFF1, TFF2, and TFF3) are small and stable molecules secreted by the mammalian(More)
PURPOSES Robotic gastrectomy (RG), as an innovation of minimally invasive surgical method, is developing rapidly for gastric cancer. But there is still no consensus on its comparative merit in either subtotal or total gastrectomy compared with laparoscopic and open resections. METHODS Literature searches of PubMed, Embase and Cochrane Library were(More)
PURPOSE To define the effects of body mass index (BMI) on operative outcomes for both gastroenterological and cardiovascular surgery, using the National Clinical Database (NCD) of the Japanese nationwide web-based database. METHODS The subjects of this study were 288,418 patients who underwent typical surgical procedures between January 2011 and December(More)
BACKGROUND Postoperative complications such as anastomotic leakage were reported to be a major independent prognostic factor for long-term survival in gastrointestinal malignancies. This study sought to clarify the prognostic significance of postoperative inflammatory complications specifically for patients with gastric cancer. METHODS This study included(More)
PURPOSE Locoregional recurrent gastric cancer is commonly treated by systemic chemotherapy. The effectiveness of surgical treatment, in terms of complete tumor resection, is unknown. METHODS We reviewed the case histories of 36 patients with locoregional recurrent gastric cancer, selected for surgical treatment by careful preoperative assessment. Patient(More)
BACKGROUND The safety of surgery for gastric cancer in the elderly has been shown previously. However, potentially fatal complications based on an established severity grading system were not well described, and associated risk factors have not been assessed. The present study sought to examine severity-dependent postoperative complications after(More)
BACKGROUND The prognosis of patients with gastric cancer and para-aortic lymph node (PALN) metastasis is poor. Recent Japanese randomized trials concluded that prophylactic PALN dissection is not effective for curable advanced gastric cancer. However, the value of curative resection in patients with pathologically positive PALN is not determined yet. (More)
