Abstract:
Objective To evaluate the diagnostic value of endoscopic miniprobe ultrasonography (MPS) and endoscopic therapies under the guidance of MPS in gastrointestinal submucosal tumors. Methods Patients with submucosal tumors of lower digestive tract were given MPS under colonoscope. Endoscopic therapy or surgery had been taken according to different deriving layers of submucosal tumors. The ultimate diagnosis was confirmed by histology. Results Twenty patients with submucosal tumors were diagnosed with MPS under colonoscope, including 9 patients with stromal tumors, 5 patients with lipoma, 3 patients with car-cinoid, 2 patients with abscess,1 patient with intestines pneumatosis. Four patients with benign stromal tumors derived from muscularis mueosa and 2 patients with carcinoid were resected by endoscopy. Two patients with abscess and 1 patient with intestines pneumatosis were puncture under endoscopy. Three patients with benign stromal tumors from muscularis propria, 2 patients with malignant stromal tumors, 2 patients with lipama and 1 patient with careinoid were resected surgically. 88.24% submucosal tumors diagnosed by MPS were identified by pathology. Three cases were followed-up by endoscopy. Conclusions Different layers of gastrointestinal tract with submucosal tumors can be distinguished clearly by MPS leading to definite diagnosis of submucesal tumors. MPS can play an important role in selecting treatment procedures.
