“…Furthermore, a higher incidence of postoperative rupture was observed when endoscopic biopsies had been taken before the procedure. Although we did not observe complications due to preoperative biopsies, we agree that biopsy is not necessary when morphologic examination (CT scan/EUS [8]) indicate that benign behavior is very likely [31].…”

“…EUS is highly accurate in the visualization of submucosal lesions and their sonographic layer of origin within gastrointestinal wall. Concerning SMT of the digestive tract, several studies have been published mainly in upper digestive tract [2][3][4] , but there have been few studies on SMT of the lower digestive tract. The aim of this study was to assess the value of EUS in the diagnosis of SMT of the large intestine and determine their imaging characteristics.…”

AIM:To evaluate the role of miniprobe ultrasonography under colonoscope in the diagnosis of submucosal tumor of the large intestine, and to determine its imaging characteristics. METHODS:Thirty-five patients with submucosal tumors of the large intestine underwent miniprobe ultrasonography under colonoscope. The diagnostic results of miniprobe ultrasonography were compared with pathological findings of specimens by biopsy and surgical resection. RESULTS:Lipomas were visualized as hyperechoic homogeneous masses located in the submucosa with a distinct border. Leiomyomas were visualized as hypoechoic homogeneous mass originated from the muscularis propria. Leiomyosarcomas were shown with inhomogeneous echo and irregular border. Carcinoids were presented as submucosal hypoechoic masses with homogenous echo and distinct border. Lymphangiomas were shown as submocosal hypoechoic masses with cystic septal structures. Malignant lymphomas displayed as hypoechoic masses from mucosa to muscularis propria, while pneumatosis cystoids intestinalis originated from submucosa with a special sonic shadow. One large leiomyoma was misdiagnosed as leiomyosarcoma. CONCLUSION:Endoscopic miniprobe ultrasonography can provide precise information about the size, layer of origin, border of submucosal tumor of the large intestine and has a high accuracy in the diagnosis of submucosal tumor of the large intestine. Pre-operative miniprobe ultrasonography under colonoscope may play an important role in the choice of therapy for submucosal tumor of the large intestine.Zhou PH, Yao LQ, Zhong YS, He GJ, Xu MD, Qin XY.

“…Our clinical research demonstrated that MUPs could not only diagnose digestive tract diseases, but also provide treatment plans for these diseases [27][28][29][30] . MUPs had a very important diagnostic value in deciding the size, location, layer origin and nature of gastrointestinal submucosal lesions.…”

AIM:To investigate the clinical value of miniature ultrasonic probes (MUPs) for the diagnosis and treatment of digestive tract diseases. METHODS:Endoscopic ultrasonography (EUS) was performed for patients with its indications with 7.5-20 MHz MUPs and double-cavity electronic endoscope. According to the diagnosis of MUPs, patients who had indications of treatment received endoscopic resection or surgical excision. Postoperative histological results were compared with the preoperative diagnosis of MUPs. A few patients without endoscopic resection or surgical excision were periodically followed up with MUPs. RESULTS:A total of 537 patients were examined by MUPs, of them, 256 were diagnosed with gastrointestinal submucosal lesions, 146 with pseudo-submucosal lesions, 50 with digestive tract cancers, 17 with peptic ulcer, 11 with cholecystolithiasis, 8 with chronic pancreatitis, and 2 with achalasia and 47 were diagnosed as normal. After MUPs examinations, 220 patients received endoscopic resection or surgical excision, and the postoperative histological results of 211 patients were completely consistent with the preoperative diagnosis of MUPs. The diagnostic accuracy of MUPs was 95.9%. The result of follow-up with MUPs indicated that gastrointestinal leiomyoma, lipoma, phlebangioma and cyst were unchanged within 1-2 years. The patients who received endoscopic resection or centesis did not have any complications. CONCLUSION:MUPs are of value in diagnosing gastrointestinal submucosal lesions, staging of digestive tract cancers and biliary-pancreatic diseases. They play a very important role in making therapeutic plans.
