According to different contrast agents in radiography, patients were divided into the study group (CO2 combined with contrast agent) and the control group (contrast agent alone). There were 23 cases in the study group and 20 cases in the control group. Total postoperative bilirubin(TBIL), white blood cell(WBC), procalcitonin(PCT)and the incidence of complications in the two groups were compared. \u0000 \u0000 \u0000Results \u0000The endoscopic procedure ranged from 50 min to 70 min.

It was conducted in Chinese mainland between August 30th, 2017 and December 30th, 2017. Data were collected through the online survey and reality survey at 385 hospitals. A total of 373 hospitals gave feedbacks and 7 hospitals were unqualified for further analysis after data checking, so 366 hospitals were included for final analysis, with a responding rate of 95.1%. Information on practice status of hospitals with enteroscopies and enteroscopists were collected. The chi-squared test was used for comparison of data between eastern and central and western regions. \u0000 \u0000 \u0000Results \u0000The hospitals owning enteroscopies accounted for 47.0% (172/366), 154/172 (89.5%) were tertiary referral hospitals, 112/172 (65.1%) established enteroscopy units, and 84/172 (48.8%) owned X-ray exclusive for enteroscopy. The proportion of enteroscopists with senior title was 40.3% (50/124), female enteroscopists accounted for 42.7% (53/124). Most enteroscopists aged 31-40 (50.8%) and 41-50 years (27.4%). 43.0% (74/172) hospitals employed only 1-2 enteroscopists. The diagnostic cases per year were less than 50 cases in 51.2% hospitals (88/172). The therapeutic cases per year were less than 10 cases in 51.7% hospitals (89/172). Nineteen of 124 (15.3%) of enteroscopists didn′t receive standard training. The number of hospitals performing enteroscopies in eastern regions was higher than that in central and western regions [111(51.6%) VS 61(40.4%), P=0.034].

The value and limitation of EUS for SMT were investigated according to the final pathology. \u0000 \u0000 \u0000Results \u0000For the lesion distribution, 66 were in esophagus, 108 in stomach, 2 in duodenum and 35 in rectum. The accuracy of tumor origin by EUS was 99.5% (210/211). The accuracy of tumor nature by EUS was 75.8% (160/211). For the lesions originated from different locations, the diagnostic accuracy for lesion originated from esophageal mucosa/submucosa, esophageal muscularis propria, gastric mucosa/submucosa, gastric muscularis propria, duodenal submucosa, rectal mucosa/submucosa by EUS were 90.0%(54/60), 83.3%(5/6), 31.0%(13/42), 89.4%(59/66), 50.0%(1/2), 82.9%(29/35), respectively. With respect to hypoechoic lesions, leiomyoma, leiomyoma/gastrointestinal stromal tumor, and neuroendocrine tumor were the predominant type of tumor originated from esophageal mucosa, gastrointestinal muscularis propria and rectal mucosa/submucosal, respectively. \u0000 \u0000 \u0000Conclusion \u0000Although EUS is indispensible for the diagnosis of gastrointestinal submucosal tumor, it plays a limited role in the differential diagnosis of various lesions originated from gastric mucosa and submucosa. Since part of the submucosal tumors may be potential for malignant development, an diagnosis made by EUS should be more careful. \u0000 \u0000 \u0000Key words: \u0000Endoscopy; Endoscopic ultrasonography; Submucosal tumor","PeriodicalId":10072,"journal":{"name":"Chinese Journal of Digestive Endoscopy","volume":"36 1","pages":"491-494"},"PeriodicalIF":0.0,"publicationDate":"2019-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45299301","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
