Access to the bypassed portion of the stomach after Roux-en-Y gastric bypass remains a challenge. We present a case of 64-year-old woman who presented with gastric outlet obstruction. We used a novel endoscopic technique to access the bypassed stomach by creating a jejunogastrostomy using a specialized stent, which allowed the insertion of a pediatric gastroscope to examine the bypassed portion...

AIM In recent years several studies have shown increasing rate of upper gastric cancers regarding to decrease in distal gastric cancers. The aim of this study was to describe the trend of gastric cancers by location in Iran, which is one of the countries with high prevalence of gastric cancers. METHODS All registered cases of gastrectomy in Tehran Cancer Institute from 1969 through 2004 were ...

BACKGROUND The presence of squamous epithelium in the stomach is only occasionally encountered and is associated with prolonged mucosal injury. Squamous metaplasia in patients with cancer is relatively rare and only four cases have been reported in the stomach, all of which have been associated with squamous cell carcinomas. We present the first case of exuberant squamous metaplasia in a patien...

The aim of this retrospective study is to evaluate the diagnostic yields of combining fine needle aspiration (FNA) with brushing cytology (BC) in clinical work-up of pancreatic ductal adenocarcinoma. The study included a total of 97 patients who underwent both FNA and BC along with histologic/clinical follow-up (F/U). Cytologic diagnoses were categorized as negative for neoplasm (NEG), atypical...

BACKGROUND Metastases to the stomach from an extra-gastric neoplasm are an unusual event, identified in less than 2% of cancer patients at autopsy. The stomach may be involved by hematogenous spread from a distant primary (most commonly breast, melanoma or lung), or by contiguous spread from an adjacent malignancy, such as the pancreas, esophagus and gallbladder. These latter sites may also inv...

Pancreatic cancer carries a poor prognosis, especially invasive ductal carcinoma of the pancreas. We present here the case of a 76-year-old man who developed synchronous double cancers of the stomach and pancreas. He was referred to our hospital in December, 1997, with a provisional diagnosis of carcinoma of the stomach. Laboratory data on admission showed normal levels except for the serum car...

Approximately 23,000 new gastric cancer cases and 12,000 associated deaths occur annually in the United States. Intestinal metaplasia and gastric epithelial dysplasia are precursor lesions to gastric adenocarcinoma, but are not readily detectable clinically, radiographically, or endoscopically. A noninvasive method of precursor detection would require the ability to distinguish precursor lesion...

Alpha-fetoprotein (AFP) producing gastric adenocarcinoma is considered as a rare subtype of gastric adenocarcinoma. Compared with AFP non-producing gastric adenocarcinoma, our study and other previous studies showed that AFP producing gastric adenocarcinoma is more aggressive and prone to liver metastasis. Using the Protein Pathway Array, 11 of out of 286 proteins tested were found to be differ...

We describe herein a recurrent catheter-related (Port-A-Cath; Smiths Industries Medical Systems [SIMS] Deltec, Inc., St. Paul, Minn.) infection caused by multidrug-resistant Mycobacterium chelonae with two colonial morphotypes in a 53-year-old woman with gastric adenocarcinoma. Four isolates recovered from this patient within a 3-month period were found to belong to a single clone on the basis ...
