内镜前置活检钳对右半结肠息肉检出率的影响

Effect of endoscopic prebiopsy forceps on the detection rate of polyps in the right semicolon

摘要:

目的 探讨内镜前置活检钳方法对右半结肠息肉检出率的影响。方法 收集2022年3月－2022年12月该院诊治的148例经普通电子结肠镜检出右半结肠息肉，于1个月内采用内镜前端前置活检钳方法复检，并行内镜下治疗患者的临床资料，比较两组患者息肉检出数、息肉大小、形态和病理学诊断差异。结果 普通肠镜检查组在右半结肠共检出168枚息肉，采用内镜前置活检钳方法复检，普通肠镜检查组漏诊息肉41枚，漏诊率为19.62%。两组患者 < 5 mm息肉检出率比较，差异有统计学意义（P < 0.05）。两组患者息肉形态均以广基隆起型为主，病理性质以管状腺瘤为主，差异均无统计学意义（P > 0.05）；两组均未发生出血和穿孔等并发症。结论 内镜前置活检钳方法能明显提高右半结肠息肉检出率，特别是可以在术中探寻到曾经“消失”的术前确定的肠息肉和直径更小的肠息肉，值得临床进一步推广。

Abstract:

Objective To investigate the effect of endoscopic prebiopsy forceps on the detection rate of polyps in the right semicolon.Method Clinical data of 148 patients diagnosed and treated from March 2022 to December 2022 who were detected as polyps in the right semicolon by general electronic colonoscopy were collected, and clinical data of the patients who underwent endoscopic prebiopsy forceps were re-examined and the patients underwent endoscopic treatment within 1 month. The differences in general data, polyp number detected, polyp size, morphology and pathological diagnosis between the two groups were analyzed and compared.Results 168 polyps were detected in the right semicolon in the general colonoscopy group, and 41 polyps were missed in reexamination using endoscopic prebiopsy forceps, with a missed diagnosis rate of 19.62%. The detection rate of < 5 mm polyps was higher in the endoscopic prebiopsy forceps group than that of general colonoscopy group, the difference was statistically significant (P < 0.05). The polyps in the two groups were mainly wide-basal type, and the pathological properties were mainly tubular adenoma, there was no statistical significance among all groups (P > 0.05). No complications such as bleeding and perforation occurred in the two groups.Conclusion Endoscopic prebiopsy forceps can significantly improve the detection rate of polyps in the right semicolon, in particular, the intraoperative search for disappeared preoperatively identified intestinal polyps, as well as smaller diameter intestinal polyps,which is worthy of further clinical promotion.
