The stomach of the American lobster (Homarus americanus) is located in the cephalothorax, between the rostrum and the cervical groove. The anterior end of the stomach is defined by the mouth opening and the posterior end by the bottom of the pylorus. Along the dorsal side of the stomach lies the stomatogastric nervous system (STNS). This nervous system, which contains rhythmic networks that und...

Gastric cancer in the excluded stomach after Roux-en-Y gastric bypass is a rare finding and most reported diagnoses are made via surgery. Endoscopic access to the excluded stomach is difficult, even with balloon-assisted enteroscopy. We present the case of a 74-year-old woman with malignant gastric outlet obstruction of the excluded stomach, 41 years after Roux-en-Y gastric bypass. Minimally in...

We previously reported that cascade stomach was associated with reflux symptoms and esophagitis. Delayed gastric emptying has been believed to initiate transient lower esophageal sphincter relaxation (TLESR). We hypothesized that cascade stomach may be associated with frequent TLESR with delayed gastric emptying. Eleven subjects with cascade stomach and 11 subjects without cascade stomach were ...

background gastric dysplasia (gd) is a precursor lesion of gastric adenoâ­carcinoma. intestinal type gastric carcinoma commonly shows microsatellite instability (msi) and the diffuse type is associâ­ated with down regulation of e-cadherin. her-2/neu is over-expressed in some cases of gastric cancer. in this study, msi and expression rates of her-2/neu and e-cadherin in gd were evaluated. me t h...
