To the best of our knowledge, this is the first report of IgG4-related gastric ulcer(More)
BACKGROUND Recently, several authors reported on the Protein Chip approach to analyze serum. They used SELDI-TOF-MS (surface enhanced laser desorption/ionization-time of flight-mass spectrometry) to identify patients with cancers of various origins in a highly sensitive and specific manner. In the current study, a similar approach was employed to analyze(More)
BACKGROUND AND AIM Secondary stomach cancer in lesions of the remnant stomach occurs relatively soon after distal gastrectomy using the Billroth I reconstruction procedure.

The use of a self-expandable metallic stent (SEMS) as a bridge to surgery (BTS) for obstructive colorectal cancer is known to be effective. However, whether the use of a SEMS as a BTS for obstruction induced by effective chemotherapy (CTx) is useful is unknown. We present the case of a 54-year-old female patient with colorectal cancer who underwent SEMS(More)
