Upper gastrointestinal tract augmentation is a morphological change that refers to tumors (including venous tumors) originating from the mucosa and submucosa as well as augmentation caused by extramural organs and tumor compression, except for esophageal cancer, gastric cancer, duodenal cancer and other mucosal augmentation lesions that can be directly observed by ordinary gastroscopy and confirmed by biopsy, other augmentation lesions are more difficult to diagnose by gastroscopy and X-ray because most of them are located in the submucosa, while ultrasound gastroscopy can clearly show the level of tissue origin of the upper gastrointestinal tract and its surrounding structures. Ultrasonic gastroscopy can clearly display the upper gastrointestinal canal wall and its surrounding structures, which can not only distinguish between intramural and extramural lesions in the upper gastrointestinal tract, but also clarify the level of tissue origin, nature and size of the lesions, thus guiding the different treatments for different lesions. Data and methods General data From July 2008 to November 2009, a total of 154 cases of augmented lesions in the upper gastrointestinal tract were found in our hospital, all of which were confirmed by general gastroscopy, and ultrasound gastroscopy was given after excluding naked eye suspicious esophageal, gastric and duodenal cancers by routine biopsy. There were 65 cases of esophagus, 75 cases of stomach and 14 cases of duodenum. Ultrasonic gastroscopy After fasting for 4-6 hours before examination, an olympus GF-UM2000 ultrasonic gastroscope or UM-DP12-25R microprobe with frequencies of 7.5, 12.0 and 20.0 MHZ was used, and the frequencies were switched according to the situation, and the scope was routinely inserted, observed, and the lesion site was identified, and the methods such as direct contact method, water filling method or flipped body position method were used, while the gastroscope was adjusted After identifying the lesion site, direct contact method, water filling method or flipping body position method are used, while adjusting the position of the gastroscope to show the best ultrasound image of the lesion target, so as to determine the level of its origin. Treatment According to the ultrasound gastroscopy and pathology results, the lesion diameter was combined with the diameter of the lesion, and those with diameter >2cm or pathology diagnosis of malignant were referred to surgery; those with 1.3cm-2.0cm were treated by endoscopic electrocoagulation and electrodesiccation (smooth muscle tumor, lipoma, mesenchymal tumor and polyp) or needle aspiration (cyst) or regular follow-up (venous tumor); those with 0.4cm-1.3cm were treated by endoscopic ligation. .
