Laparoscopy-assisted gastrectomy (LAG) has been increasingly used for the treatment of early gastric cancer, and many advantages over open gastrectomy (OG) have been reported. However, only a few reports have assessed postoperative complications following LAG using the Clavien–Dindo classification. A total of 265 patients who underwent distal gastrectomy or(More)
61 Background: In order to explore carcinogenic and prognostic biomarkers for gastric cancer, genomic, transcriptomic and proteomic approach had been extensively investigated. However, little information is possible for metabolomics profiles in gastric cancer. As cancer cells demonstrates distinguishable growth pattern from normal cells, presence of(More)
Robot-assisted distal gastrectomy (RADG) is increasingly performed in Japan and Korea and is thought to have many advantages over laparoscopic gastrectomy. However, a prospective study investigating the safety of RADG has never been reported. The present study evaluated the safety of RADG with nodal dissection for clinical stage IA gastric cancer. This(More)
Resection margin involvement is one of the most significant risk factors for local recurrence in curative gastrectomy, and local recurrence results in anastomotic stenosis. In the present study, the effects of a positive resection margin in palliative gastrectomy on the symptoms of anastomotic stenosis and the amount of oral intake were analyzed. Between(More)
Magnetotactic bacteria (MTB) are widespread aquatic bacteria, and are a phylogenetically, physiologically and morphologically heterogeneous group, but they all have the ability to orientate and move along the geomagnetic field using intracellular magnetic organelles called magnetosomes. Isolation and cultivation of novel MTB are necessary for a(More)
A 40-year-old man presented to our department with chief complaints of nausea and abdominal pain, and was diagnosed with small intestine ileus. After hospitalization, he underwent intestinal tract decompression using an ileus tube. A small bowel tumor was suspected as the cause of the intestinal obstruction. We then performed laparoscopic surgery for(More)
We experienced changes in ultrasonographic features of hepatic parenchyma in 156 patients treated with Tamoxifen (TAM) as an adjuvant hormonal therapy for breast cancer. After the treatment with TAM subsequent to the surgery for breast cancer, 36% of patients showed changes in ultrasonographic features of the liver more than Grade 2, despite no obvious(More)
A 55-year-old man was admitted to our hospital because of abdominal distension. Computed tomography revealed an abscess in the anterior abdominal wall and invasion of the large intestine. Biopsy of the large intestine revealed adenocarcinoma. Immunohistochemically, the antigen expression profile of the tumor was positive for cytokeratin 7, cytokeratin 903(More)
Laparoscopic surgery for colorectal cancer has the advantage of being less invasive and delivering better cosmetic appearance. Although single-incision laparoscopic surgery produces excellent cosmetic results, it is considered very difficult to perform. We performed reduced port surgery (single-incision plus one or 2 ports) on 42 patients in our institute.(More)
INTRODUCTION The hemi-double stapling method (HDS) is typically used for extracorporeal Billroth-I anastomosis. We used HDS for reduced-port surgery. Laparoscopic HDS is used for intracorporeal Billroth-I anastomosis after laparoscopic distal gastrectomy. We performed reduced-port laparoscopic distal gastrectomy for gastric cancer. METHODS Reduced-port(More)
