Various surgical procedures are used to treat early gastric cancers in the upper third of the stomach (U-EGCs). However, there is no general agreement regarding the optimal surgical procedure. The medical records of 203 patients with U-EGC were collected from 13 institutions. Surgical procedures were classified as Roux-en-Y esophagojejunostomy after total(More)
The incidence of internal hernia after gastrectomy can increase with the increasing use of laparoscopic surgery, although this trend has not been elucidated. Clinical information was collected from medical records and by questionnaire for 18 patients who underwent surgical treatment for internal hernia after gastrectomy for gastric cancer in 24 hospitals(More)
E-cadherin (ECD) is one of subclasses of the cadherin family which plays a major role in the maintenance of intercellular adhesion in epithelial tissues. An immunohistochemical study of ECD expression was performed on gastric adenocarcinoma from 103 patients using our monoclonal antibody for human ECD (HECD-1). ECD was strongly expressed in normal gastric(More)
It remains uncertain whether radical lymphadenectomy combined with total gastrectomy actually contributes to long-term survival for Siewert type II adenocarcinoma of the cardia. We identified the pattern of abdominal nodal spread in advanced type II adenocarcinoma and defined the optimal extent of abdominal lymphadenectomy. Eighty-six patients undergoing R0(More)
BACKGROUND New molecular techniques have been designed to detect cancer micrometastases that are otherwise missed by conventional histologic examination. The aim of this study was to establish a sensitive and rapid genetic assay to detect lymph node micrometastasis and to assess its usefulness clinically for cervical lymphadenectomy in esophageal cancer. We(More)
The development of more sophisticated instruments has enabled advanced laparoscopic surgery. We recently devised a totally laparoscopic method of performing Billroth-I hand-sewn anastomosis and established this technique in an animal training model. This report presents the case of a 50-year-old man in whom totally laparoscopic distal gastrectomy was(More)
This pilot study was carried out to evaluate the efficacy of chemotherapy for patients with peritoneal dissemination from gastric cancer or positive lavage cytology diagnosed by staging laparoscopy. Sixteen patients were enrolled. Paclitaxel was administered at 120 mg/m2 on day 1 and S-1 was administered orally at 80 mg/m2 for 14 consecutive days, followed(More)
PURPOSE We have developed a novel molecular method of diagnosis using the technique of transcriptase-reverse transcriptase concerted reaction (TRC) for the detection of cancer micrometastasis. This study prospectively examined the clinical importance of the TRC diagnosis with peritoneal lavage fluids collected from gastric cancer operations at multiple(More)
tron emission tomography (FDG−PET) is one of the most valuable imaging meth− ods by which to establish tumor extent and size, to assess nodal disease, and to detect distant metastasis in head and neck cancer. For this reason, FDG−PET imaging has been reported to be useful for preoperative or preradiotherapy stag− ing [1,2]. However, high FDG uptake can be(More)
Mucoepidermoid carcinoma is a mixed cell tumor with both adenocarcinomatous and squamous components. We report a rare case of superficial mucoepidermoid carcinoma of the esophagus with mucosal gastric cancer. Endoscopic mucosal resection was performed on a 67-year-old man with a slight but defined depressed lesion of the thoracic esophagus and two lesions(More)
