ObjectiveTo investigate the value of capsule endoscopy in the diagnosis of small bowel diseases. MethodsThe clinical data of 359 cases underwent OMOM capsule endoscopy examination were retrospectively analyzed. ResultsIn 346 patients (96.4%) , capsule endoscopy was successfully passed the ileocecal valve; because the capsule endoscopy had failed to pass pylorus after 1 h，the capsule endoscopy were sent to the duodenum by using pyloric duodenal endoscopy in 125（34.8%）patients. Positive lesions were found by capsule endoscopy in 233 cases (64.9%). Among 54 cases of unexplained gastrointestinal bleeding patients, positive lesions were detected in 42 cases (77.8%), including 24 cases of vascular disease, 12 cases of ulcer lesions, 1 case of parasite, intestinal polyps (2 cases), small intestinal diverticulum(3 cases). Among 189 cases of abdominal pain group, positive lesions in 135 cases (71.4%), including 71 cases of erosive disease, ulcerative lesions in 37 cases, inflammatory lesions in 14 cases, 9 cases of vascular lesions, a parasite in 3 cases, 1 cases of small intestinal polyps. Among 105 cases of diarrhea, positive lesions were found in 55 cases (52.4%), including 19 cases of erosive lesions, 16 cases of ulcerative lesions, 11 cases of vascular diseases, 5 cases of macular tumor, 4 cases of small intestinal polyps. ConclusionThe diagnostic value of capsule endoscopy for small intestinal disease is rather high, especially for intestinal inflammatory disease and obscure gastrointestinal bleeding in clinical diagnosis.
