[A Case of Laparoscopic-Endoscopic Cooperative Surgery for Duodenal Neuroendocrine Tumor(NET G1)].

We report a case of duodenal neuroendocrine tumor(NET)G1 resected by laparoscopic-endoscopic cooperative surgery (LECS). A 78-year-old woman underwent upper gastrointestinal endoscopy, revealing an 8 mm, rising tumor on the anterior wall of the duodenal bulb. The tumor was pathologically diagnosed as a G1 duodenal NET, by biopsy.

Prognostic Influence of the Extent of Lymph Node Dissection and Perioperative Comorbidities in Patients with Gastric Cancer.

Background: The proportion of geriatric gastric cancer (GC) patients with comorbidities has been increasing in Japan. This study was designed to evaluate the prognostic influence of the extent of lymph node dissection (END) and perioperative morbidities in patients with GC.

Patients And Methods: Between 2008 and 2013, total of 167 patients with GC who underwent curative gastrectomy were enrolled in the study.

[A case report of cholangiectasis with cholangiocarcinoma].

This is a case report of cholangiectasis with cholangiocarcinoma in a 37-year-old female. Both computed tomography (CT) and endoscopic retrograde cholangio-pancreatography (ERCP) demonstrated gallstone, and intrahepatic bile duct dilatation with the stone. The diagnosis was intrahepatic cholangiectasis without common bile duct-dilatation.

Expression of cancer stem cell markers CD133 and CD44 in locoregional recurrence of rectal cancer.

Background: Recent findings suggest that cells with surface CD markers include cancer stem cells (CSCs) which can produce a cancer cluster, and that the presence of CSCs may be linked with prognosis. CD133 and CD44 are among the most useful markers for identification of colorectal CSCs.

Materials And Methods: An immunohistological analysis of CD133 and CD44 was performed using tissue from cases shown to be locoregionally recurrent or non-recurrent clinico-pathologically.
