Abstract:
Objective To evaluate the value of miniprobe sonography (MPS) in diagnosing gastrointestinal submucosal protrusive lesions and selecting the indicated manual for treatment. Methods According to the sizes, properties, and depth of SMTs in the gastrointestinal tract detected by the MPS, different methods of resection were performed. Results Of 24 cases, 11 SMTs lying in submucosa under 2cm in diameter (2 benign gastrointestinal stromal tumors, 3 lipomas, 5 cysts, 1 granular cell tumor) were attempted with EMR or argon plasma coagulation (APC) ; there were no complications of hemorrhage or perforation. Thirteen SMTs lying in muscularis propria or with size of SMTs above 2 cm in diameter (4 malignant GISTs, 6 benign GISTs, 1 lipoma, 2 aberrant pancreas) were performed by surgical resection. Preoperative diagnoses of SMTs by MPS were consentient with their histological diagnoses. Conclusion MPS may detect the size, property, and depth of SMTs in the gastrointestinal tract and is helpful in selecting indicated cases for endoscopic resection. Endoscopic therapy of SMTs lying in mucosa or submucosa under 2cm in diameter is a safe and effective procedure.
