Various reports have been described about occurren-ces and clinical signif icances of hezoars in the gastric remnant. Recently we experienced two cases of bezoar in the operated stomach. One was a case of which a bezoar might be produced of residua of food conglo-merated around suture threads exposed from the stoma of the Billroth-II operated stomach. In this case, suture threads were tought to be the important factor of the bezoar formation in addition to the various factors ever thought such as gastric stasis of food, delayed emptying or decreased gastric secretions. This bezoar disappeared through cutting the thread by biopsy forceps. In the other case, a rather large bezoar was found in the postgastrectomized stomach through the Billroth-I method. Erosions and superficial gastric changes obser-ved around the portion of anastomosis were found to improve shortly after when the bezoar disappeared after crushing in pieces by biopsy forceps endoscopically. This fact might show that bezoars would have some effects on the gastric mucosa.
