Abstract:
Objective To evaluate the diagnostic value of Endoscopic ultrasonography(EUS) and endoscopic therapies in gastrointestinal submucosal tumors under the guidance of EUS.Methods Patients underwent endoscopy for dyspepsia at our unit. Two hundred and thirty eight patients were found to have a presumed submucosal tumor(SMT) and all subjected to Endoscopic ultrasonography(EUS). Endoscopic therapy including endoscopic mucosal resecation(EMR), endoscopic mucosa strip removal(EMSR), snare cauterization,sclerotherapy or surgery operation had been taken according to the different deriving layers of submucosal tumors. The ultimate diagnosis was confirmed by histology.Results Seventy three stromal tumors derived from muscularis mucosa,7 carcinoid in mucosa propiria; 6 cysts, 13 lipomas, 17 etopic pancreases in stomach and 5 varices in gastric fundus derived from submucosa; 95 benign stromal tumors and 21 malignent stromal tumors derived from muscularis propria,1 carcinoid invaded muscularis propria. 61 benign stromal tumors derived from muscularis mucosa , 8 benign stromal tumors derive from muscularis propria, 8 lipomas, 4 cysts, 8 etopic pancreases and 7 carcinoids were resected by endoscopy; 33 benign stromal tumors from muscularis propria, 18 malignent stromal tumors, 2 lipoma and 2 etopic pancrease,1 carcinoid were resected surgically. Submucosal tumors 97.97% diagnosed by EUS were identified by pathology.Conclusion Different layers of gastrointestinal tract with submucosal tumors can be distinguished clearly by EUS, leading to definite diagnosis of submucosal tumors. EUS is important in selecting treatment procedures of submucosal gastrointestinal tumors and should routinely be performed on all presumptive submucosal tumors prior to attempt at removal.
