Objective    To explore the diagnostic value of OMOM capsule endoscopy on gastrointestinal tract

and its demonstration of duodenal pailla and ileal valve.     Methods    OMOM capsule endoscopy was carried out for 162 patients

aged 18-80 year

including 87 suffered from unexplained gastrointestinal bleeding

35 with diarrhea and abdominal pain

5 of colon polypi and cancer after surgery

and 35 health individuals. All patients received digestive tract X-ray

gastric endoscopy and colon endoscopy. The outcomes of different examinations were compared on the ratio of identified gastrointestinal disease

and on those of duodenal pailla and ileal valve.     Results    Among all 162 cases

intestinal examine were completed in 160 cases.  Duodenal pailla was observed in 56 cases. Out of them

29 cases were from 101 cases examed by OMOM-Ⅰ capsule (28.71%) and  27 were from 59 cases by OMOM-Ⅱ capsule (45.76%).  Significant difference was observed between the 2 capsule (P0.01).     Conclusion    OMOM capsule endoscopy  is an effective approach to examine and diagnose intestinal. But at present

capsule endoscopy still can’t take the place of gastroscopy and enteroscopy.
