[The reposition of the colon in a patient with Chilaiditi's syndrome after spinal operation in the prone position].

An 82-year-old man with Chilaiditi's syndrome underwent posterior lumbar interbody fusion surgery. The colonic gas was in the right lower lung field on the preoperative chest X-ray. But 2 years before, his chest X-ray had not been diagnosed as Chilaiditi's syndrome. Afterward he had cancer in his left lung and the radiation therapy was performed. At this time, after finishing the radiation therapy, a spinal operation was planned for his spondylosis. After the operation in the prone position, the colonic gas in the right lower lung field disappeared. The colon in the subphrenic space was repositioned to the right. The prone position may have repositioned the colon in this patient with Chilaiditi's syndrome.
