Pathological diagnosis were obtained after surgery and endoscopy detection. Results: 87 lesions were located in duodenal bulb (43.7%). Other lesions were located in descending potion (56.3%). After EUS, 42 cases were diagnosed as cyst, 39 as Brunner’s adenoma, 23 as minor papilla, 19 as lipoma, 18 as polyp, 11 as ectopic pancreas, 10 as stromal tumour, 5 as malignant tumour, 3 as neuroendocrine tumour (carcinoid Bioactive Compound Library cost tumour), 2 elevated lesions were pressured by outside organs, another 27 lesions
had no diagnosis. Endoscopic therapy were carried in 48 patients, surgery in 12 patients, endoscopic follow-up in 33 patients from 3 months to 22 months. The diagnostic accuracy of EUS was 83.8% (78/93). Conclusion: EUS can clearly expose five layers of gastrointestinal tract and histological structure of adjacent organs, which is of great help to achieve definite diagnosis of elevated lesions in duodenal selleck chemicals llc tract.

the inspectors who was lacking of warning signs and to verify the value and necessity of colonoscopy in it. Methods: Colonoscopy of 4304 patients from Jan. 2006 to Dec. 2011 were reviewed, according to the definition of lower digestive tract symptoms lacking of warning signs. It was a retrospective case study. Results: In all the 4304 patients, the male/female ration was 1:1.14, with average age 48.0 ± 13.5 years old. And it was the most common between 3 to 12 months. 82.1% of the outcome was negative. Comparing the outcomes concluding
symptom association lesions, symptom independent lesions and negative cases, it showed that females who was younger than 40 years with more than 3 months course were common in negative group. Moreover, in organic lesion cases, it could find that the male patients less than 3 month course were more common than ones more than 12 month course. 215 cases were diagnosed as colorectal cancer, and it was 5.0% PIK3C2G of all inspectors. Cases with less than 40 years were 24, between 40 to 60 years were 82 and more than 60 were 109. They was 1.9%, 3.8% and 11.8% respectively of the corresponding age group. Conclusion: It showed that the clinical symptoms were not the influent factor of the colonoscopy in those inspectors lacking of warning signs. However, the risk factors of the colorectal cancer included sex (male), age (>60) and course (<3 month). What’s more, the cancer relevance ratio was positive correlation with age. In a word, it was the first choice to use colonoscopy to inspect lower digestive tract, especially for those more than 60 year old. Key Word(s): 1. Colonoscopy; 2. Screening; 3. Organic lesion; 4.
