Clinical application of ultra-fine nasal endoscopy in digestive tract stenosis / 实用肿瘤学杂志

ABSTRACT

Objective The aim of this study was to investigate the application and clinical value of ultra-fine nasal endos-copy in the diagnosis and treatment of digestive tract stenosis. Methods A retrospectively investigation of 160 cases of nasogastricos-copy in esophageal,gastroduodenal and colorectal stenosis lesions,the detection rate of lesions under the stenosis and endoscopic treat-ment were analyzed from January 1,2016 to December 31,2017. Results In 102 cases of diagnostic examination,the passing rates of nasogastricoscopy in esophageal,gastroduodenum and colorectal stenosis were 76. 92% ,50. 00% and 88. 00% ,respectively. In the ca-ses which the endoscope could successfully pass the stenotic lesions, the detection rates of new lesions below the stenosis were 8. 89% ,0 and 27. 78% ,respectively,in esophageal,gastroduodenum and colorectal stenosis. A total of 58 cases of digestive tract ste-nosis were treated with endoscopic gastroscopy. Among them,46 cases had stenosis and the pass rate was 79. 31% . Conclusion Ultra-fine nasal endoscopy can significantly improve the completeness and accuracy of endoscopic diagnosis in patients with digestive tract stenosis that cannot be passed by standard gastrointestinal endoscopy. It can also be used for endoscopic treatment of digestive tract stenosis.
