Attitude control system combined with attitude controllable intelligent capsule endoscope for stomach examination

Abstract

Objective To evaluate the applicable value of attitude control system combined with at- titude controllable intelligent capsule endoscope for stomach examination. Methods A total of 15 patients were recruited to the study. Manipulability of movement and posture change of capsule endoscope, diagnostic efficacy for such locations as gastric cavity, bulb and descending duodenum, image quality and patients＇ compliance were assessed. Results The procedure was completed in 14 patients. One failed due to downfall of the endoscope to duodenum within 5 min. Mean operation time was （23.7 ± 6. 5 ） min （from 5 to 30 min）. Ten cases of superficial gastritis, one case of superficial gastritis with bile regurgitation and 1 case of ulceration of the duodenal bulb were diagnosed. No abnormalities were found in 3 others. Endoscopic ima- ges were of high quality and only a few were influenced by gastrointestinal peristalsis. All patients showed compliance with no discomfort. Capsule endoscopes were discharged within 2 or 3 days. Conclusion Atti- tude control system combined with attitude controllable intelligent capsule endoscope in stomach examination is feasible and valuable in clinic.
