Abstract:
Objective To analyze the clinicopathological characteristics of upper gastrointestinal submucosal tumors ( SMTs ) . Methods Clinicopathological data of 1 743 patients with 1 775 upper gastrointestinal SMTs in our department from January 2008 to December 2012 were retrospectively analyzed. Results The first finding was that in 702 esophagus cases,leiomyoma(92?59%,650/702) was the most common type of esophageal SMTs. Second, in 1 045 gastric cases, there were 405 lesions at gastric fundus, the most common type of SMTs were 249 ( 61?48%) GISTs and 144 ( 35?56%) leiomyoma. In 307 lesions located at body,the most common type of SMTs were 143( 46?58%) GISTs and 90( 29?32%) leiomyoma. In 191 lesions located at antrum, the most common type of SMTs were 83( 43?46%) heterotopia pancreas and 45(23?56%) hamartoma, followed by 28(14?66%) lipoma and 20(10?47%) GISTs. In 142 lesions located at cardia, the most common type of SMTs was 110 ( 77?46%) leiomyoma. Third, in 28 duodenum cases, there were 19 lesions at duodenal bulb, the most common type of SMTs was 10 heterotopia pancreas, 4 Brunner gland adenoma and 3 GISTs. In 9 lesions located at descending duodenum,the most common type of SMTs was 4 lipomyoma, followed by 2 ectopic pancreas,1 GISTs and 2 others. Conclusion Leiomyoma is the most common type of esophageal SMTs. In gastric fundus and body, the most common type of SMTs are GISTs and leiomyoma. In antrum, the most common type of SMTs are heterotopia pancreas and hamartoma, but in cardia, that is leiomyoma.In duodenal bulb, the most common type of SMTs are heterotopia pancreas, Brunner gland adenoma and GISTs,and in descending duodenum, is lipomyoma.
