ABSTRACT
Objective To explore the endoscopic and clinicopathological characteristics of upper gastrointestinal tract metastasis,it can improve the diagnosibility of endoscopists and pathologists. Methods Three cases of upper gastrointestinal tract metastasis and seven cases in the related literature were studied, and its endoscopy and clinicopathological findings were analyzed with a review of the literature, whose gastrointestinal symptoms were the first manifestation. Results Case 1 endoscopic detection of esophageal ulcer lesions, pathological diagnosis of metastatic cancer, considering the source of the lung, confirmed by imaging examination; Case 2 showed that the gastric body was prominent, and the pathological diagnosis was squamous cell carcinoma. It was suggested that the clinical examination should be carried out without metastasis, and then confirmed by imaging examination and bronchoscopy biopsy; Case 3 endoscopic examination revealed multiple polypoid lesions in the stomach and duodenum, and was pathologically diagnosed as metastatic renal cell carcinoma. 3 patients were correctly diagnosed, thus avoiding unnecessary radical surgical treatment. 7 cases of patients in the literature were aged, they were also in a variety of gastrointestinal symptoms and the first diagnosis, no previous history of cancer, endoscopic lesions in the stomach or duodenum, supplemented by immunohistochemical staining in pathological diagnosis were diagnosed as metastases, the primary tumor site without organ specific. Conclusion The metastasis of upper gastrointestinal tract is rare, especially when the gastrointestinal symptoms were the first manifestation,it is usually missed and misdiagnosed. The diagnosis relies on the endoscopic and pathological examination, supplemented by the imaging examination, so the patients could get effective treatment in time.
ABSTRACT
Objective To study the screening value of color doppler flow imaging (CDFI) for gastroesophageal reflux(GER).Methods Through the window of left lobe liver, the abdominal esophageal length,the phenomenon of GER and the frequency of GER were detected by CDFI in 55 children with GER and 55 control group.Results Abdominal esophagus was identified by CDFI in every children. The abdominal esophageal length was shorter in refluxers than that in control group. A significant correlation was found between its length and the age of control group.To diagnose GER with CDFI ,its accuracy was 98.18%,and its specificity was 76.36%.Conclusions Visualization and measurements of the abdominal esophagus are readily achieved with CDFI in children.Abdominal esophageal length is shorter in refluxers than that in control group. CDFI is a rapid method of screening GER.
ABSTRACT
Objective To study whether gastric liquid emptying is delayed in children with gastroesophageal reflux and its clinical significance. Methods At different times after meal, the gastric antral diameters were measured by real - time ultrasonography in 55 children with gastroesophageal reflux and 55 controls. Results At 20 min,60 min after meal , there was a significant difference in gastric emptying rate between case groups and control groups, respectively(P
