目的 探讨超细鼻胃镜在消化道狭窄性病变诊断与治疗中的应用与临床价值.方法 回顾性分析2016年1月1日—2017年12月31日160例鼻胃镜在食管、胃十二指肠、结直肠狭窄性病变中的通过率、狭窄下方病变检出率及内镜下治疗的情况.结果 在102 例诊断性检查中,鼻胃镜在食管、胃十二指肠、结直肠狭窄中的通过率分别为76. 92% 、50. 00% 、88. 00% ;在镜身可顺利通过狭窄病变的病例中,狭窄下方新病变检出率分别为8. 89% 、0、27. 78% .利用鼻胃镜共完成58例消化道狭窄相关内镜下治疗,其中46例镜身可通过狭窄病变,通过率为79. 31% .结论 在标准胃肠镜无法通过的消化道狭窄相关疾病中,超细鼻胃镜可以显著提高内镜下诊断的完整性、准确性,还可以用于消化道狭窄性病变的内镜下治疗.%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.
