A 81-year-old female was admitted to our hospital to undergo endoscopical treatment for a gastric adenoma and received YAG-laser therapy. The gastric adenoma was completely removed by laser therapy. However, following treatment, she complained of having mucous feces. Although she had undergone a colonoscopy twice during the previous six month, we examined her large intestine using colonoscopy and barium enema. A colonoscopy revealed a large-flat elevated lesion of the same color as the surrounding mucosa and no transmucosal vascularity of the rectum. A well demarcated flat lesion 4 cm in size with conglomerated nodules on its surface was confirmed using the dye-spraying contrast method with 0.2% indigo carmine solution. A lower anterior resection of the rectal lesion was performed and the patient is now living and well 16 month following surgery. We believe that, if we encounter gastric adenomas, more careful observation and use of the dye-spraying contrast method are necessary for the detection of adenomas or cancers in the colon.

Hookworm is one of the most common parasites in the world, but can be missed on stool examination. We report a 31-year-old man who was complaining of epigastric discomfort, with laboratory findings of iron-deficiency anemia and eosinophilia. He was found to be infected with hookworm (Ancylostoma duodenale), which was directly detected and retrieved from the duodenum with biopsy forceps during upper gastrointestinal endoscopy. We eliminated his infection successfully by the Damaso de Rivas-Kihara modified method and oral administration of pyrantel pamoate. This report indicates that it is important to check carefully even in the distal duodenum at routine upper gastrointestinal endoscopy whenever parasitic disease is suspected but is hard to diagnose because of a limited number of eggs in feces.
