It deals with the group of body parts/organs which help in the process of converting food into energy and other nutrients to feed the entire body in both humans and animals. The main parts of digestive system are: Mouth, Esophagus, Stomach, Small intestine, Liver, Pancreas and Colon. Open Access eBooks is publishing an eBook on RECENT STUDIES ON DIGESTIVE SYSTEM ANATOMY.

Study on Morphology and Pathogenesis of Type 1 ECL- Cell Gastric Carcinoids

Author(s): Vuka Katic

Gastric carcinoids develop from neuroendocrine cells. There are a few types of neuroendocrine cells in the stomach, mainly G, D, ECL, D1, Ec, P and X cells [1-5]. Gastric carcinoids in the stomach derive from ECL cells, the dominant type of endocrine cells of the corpus and fundus mucosa realising histamine which is responsible for parietal cell stimulation [6-8]. Autoimmune atrophic fundic gastritis induces both hipergastrinemia and pernicious anemia (PA), as well as the changes in both epithelium and endocrine cells in gastric mucosa [6-9]. The most important complicatins of hipergastrinrmia are: gastric cancer and enterochromaffin-like cell (ECL- cell) carcinoid [7-10]. Gastric carcinoids (GCs) constitute 4% of all gastrointestinal endocrine tumors and 0.3% of gastric neoplasia [6-10].

Endoscopic Microanatomy of the Human Gastrointestinal Mucosa

Author(s): Hugo Uchima*; Kenshi Yao

Dual wavelength imaging with bandwidth narrowing is an image-enhanced endoscopy technology based in the interaction of narrow band spectrum of light with the mucosal surface and the hemoglobin of the microvasculature. Narrow-band imaging (NBI) , blue light imaging (BLI) and Optical enhancement (OE) are examples of this technology. The study of the microsurface structure and the microvascular architecture of the gastrointestinal mucosa have medical implications, specially in the diagnosis and characterization of early neoplastic lesions allowing a treatment with organ preservation.
