Detecting gastric occult blood: A wireless capsule system for screening upper gastrointestinal cancer

Surgical treatment of early cancer has a good prognosis. Prior research reported that gastric occult blood detection can be used to screen early upper gastrointestinal cancer. This paper proposes a gastric occult blood detection (GOBD) capsule system to detect occult blood in gastric juice for screening upper gastrointestinal bleeding and tumor diseases based on colloidal gold immunochromatography. In-vitro and in-vivo experiments are conducted to testify the overall function of the system. Experiments show that all occult blood test results are displayed on the external PC. Results demonstrate that the GOBD capsules in our experiments can detect the occult blood, and send the occult blood information outside from normal saline and animal bodies. This information is then received by external receiver and displayed on a PC.

Surgical treatment of early cancer of the proximal third of the stomach.

A retrospective study was conducted in search of an optimal surgical procedure for early cancer of the proximal stomach. The clinicopathological findings and survival data of 128 patients operated on during a recent period of 16 years were analyzed. Nodal metastasis was found in 12% of the patients and had a significant influence on the survival. It was more frequently observed in the undifferentiated type, regardless of the tumor size. Most metastases were found in the proximal paragastric nodes, and no metastasis was observed in the pyloric region or at the splenic hilum. These facts suggest that while the resection of paragastric nodes is advocated, neither total gastrectomy nor splenectomy is required simply for the purpose of lymphadenectomy.
