Primary Outcome Measures:
  • the percentage of complete visualization of anatomic landmarks [ Time Frame: 2 year ] [ Designated as safety issue: No ]
    the percentage of patients in whom there was complete visualization of the gastric surface in the antrum, body, and fundus and identification of the cardia and pylorus

  • examination time and the percentage of abnormal finding [ Time Frame: 2 year ] [ Designated as safety issue: No ]
    examination time and the percentage of abnormal findings seen on gastroscopy that were reproducible by capsule endoscopy

Secondary Outcome Measures:
  • adverse effect [ Time Frame: 2 year ] [ Designated as safety issue: Yes ]
    any discomfort like chest pain, nausea will be documented. capsule retention(defined as not extrusion in 14 days)will be documented.

  • Acceptability [ Time Frame: 2 year ] [ Designated as safety issue: Yes ]
    Acceptability to patients was assessed by means of a questionnaire, with ratings on a scale of 0 to 10 and examination chosen for next time. completed in the recovery room immediately after capsule examination.
