title: Gastric emptying and bezoars.
abstract: Bezoars are conglomerates of undigested material in the stomach, which appear as a late complication of gastric surgery and are presumably related to secondary motility changes. We studied the gastric emptying of a technetium-99m-(Tc 99m) labelled solid meal in 10 patients who presented with a bezoar 1 to 20 years after vagotomy and pyloroplasty, vagotomy and antrectomy, vagotomy and gastrojejunostomy, or hemigastrectomy. The results were compared with the emptying data of operated patients without bezoars. The gastric retention of Tc 99m-labelled solids at 45, 75, and 105 minutes was 85 +/- 15 percent (mean +/- SD), 79 +/- 17 percent, and 65 +/- 24 percent, respectively. No differences were found when results were compared with those of operated patients without bezoars. We concluded that factors other than the gastric digestive phase are the main contributors to bezoar formation.
