目的

探讨窄带成像（NBI）在不同肠道清洁度下对升结肠息肉检出率的影响。

方法

回顾性分析宿迁市第一人民医院内镜中心2016年1月到2017年6月行结肠镜检查的1029例患者，肠道清洁度评分0~1分者为A组，共549例，2分者为B组，共480例。A组中NBI观察升结肠者共260例（A1组），常规观察者共289例（A2组）；B组NBI观察升结肠者共231例（B1组），常规观察升结肠者249例（B2组）。A1组和A2组、B1组和B2组之间升结肠息肉的检出率对比予以χ²检验，退镜观察时间比较予以t检验。

结果

A1组升结肠息肉检出率为6.92%（18/260），观察时间为（127.93±12.21）s，A2组升结肠息肉检出率为3.11%（9/289），观察时间为（126.17±11.32）s；B1组升结肠息肉检出率为5.19%（12/231），观察时间为（125.45±15.16）s，B2组升结肠息肉检出率为4.42%（11/249），观察时间为（128.88±8.26）s。A1组较A2组升结肠息肉检出率高，差异有统计学意义（χ²=4.246，P=0.039），观察时间比较差异无统计学意义（t=1.751，P=0.081）；B1组较B2组检出率稍高，差异无统计学意义（χ²=0.159，P=0.690），观察时间比较差异无统计学意义（t=1.972，P=0.068）。

结论

NBI观察能显著提高肠道清洁度0~1分患者的升结肠息肉检出率，不能显著提高肠道清洁度评分2分患者的升结肠息肉检出率。

Objective

To evaluate the influence of narrow-banding imaging on the detection rate of polyps in the ascending colon in patients with different intestinal cleanliness.

Methods

A retrospective study was performed on 1029 patients who underwent colonoscopy at the Endoscopy Center of the No. 1 People′s Hospital of Suqian from January 2016 to January 2017. These cases were divided into two groups by intestinal cleanliness score: A and B. Group A had an Ottawa intestinal cleanliness score of 0 or 1 (n = 549), and group B had an intestinal cleanliness score of 2 (n = 480). In group A, 260 patients underwent NBI to detect ascending colon polyps (subgroup A1), and 289 underwent conventional imaging (subgroup A2). Similarly, 231 patients in group B received NBI (subgroup B1), and 249 patients underwent conventional imaging (subgroup B2). The detection rate of ascending colon polyps and examination time were compared between subgroups A1 and A2 and subgroups B1 and B2.

Results

The detection rate of ascending colon polyps and examination time were 6.92% (18/260) and (127.93±12.21) seconds in subgroup A1, 3.11% (9 /289) and (126.17±11.32) seconds in subgroup A2, 5.19% (12/231) and (125.45±15.16) seconds in subgroup B1, and 4.42% (11/249) and (128.88±8.26) seconds in group B2, respectively. The detection rate of ascending colon polyps was significantly higher in subgroup A1 than in subgroup A2 (P<0. 05), although there was no significant difference in the examination time between the two subgroups. Either the detection rate of ascending colon polyps or examination time did not differ significantly between subgroups B1 and B2 (P>0. 05).

Conclusion

Narrow-banding imaging can significantly increase the detection rate of ascending colon polyps in the case of intestinal cleanliness score of 0 or 1, but not in patients with an intestinal cleanliness score of 2.
