[A case of obstructive ileus following the upper Gi barium swallow study with condensed barium due to severe constipation].

A 64-year-old woman visited my clinic with complaints of abdominal distension, constipation, and nausea. Since abdominal X-ray showed severe obstructive ileus following the upper GI barium swallow study, the patient was sent immediately to Saga Medical School Hospital for the emergency operation. As the result of the left hemicolectomy, two obstructive lesions were found at the sigmoid colon and the transverse colon. Nowadays, as the population of aged people increases and Japanese diet changes, colon cancers are increasing more rapidly. Since the half of colon cancers doesn't have any clinical symptoms of obstruction, the upper GI barium swallow study with condensed barium might lead a patient to some type of dangerous situation.
