The clinical trial for the utility and safety of postoperative radiological examinations using small size X-ray imaging machine in patients receiving gastrointestinal surgery.

o difference in radiographic evaluation was observed in cases in which imaging was performed by each method. No adverse events were observed. There were 21 cases (19.8%) in which imaging was discontinued. Ten were due to equipment errors, and 11 were due to cases in which the principal investigator or research assistant judged that it would be difficult to continue the study. Whether or not we can respond to equipment errors is considered to be an issue for the future.
