Bone Disease after Gastric Surgery: Cooperative, Multihospital Study in Japan

An age- and sex-matched comparative study of bone disorders between control and patient groups after gastric surgery was performed with the cooperation of a number of hospitals in Japan. In males after gastric surgery a high incidence of bone atrophy was observed in the 5th and 6th decades. In females, however, there was no marked difference between patient and control groups. Evaluation by operative procedures showed that the incidence of bone atrophy was higher in male patients after Billroth II or total gastrectomy than in the patients after Billroth I gastrectomy.
