内镜下钳夹活检诊断胃息肉病变性质及与病理诊断的差异

Difference between endoscopic clamp biopsy and pathological diagnosis of gastric polyp

目的 分析内镜下钳夹活检诊断胃息肉的病变性质,探究其与内镜下胃息肉切除术后标本的病理诊断结果的差异。方法回顾性选取2021年2月~2022年2月于本院消化内科行内镜下钳夹活检诊断及内镜下胃息肉切除术的145例患者的临床资料,分析内镜下钳夹活检诊断胃息肉的病变性质,并对比其与内镜下胃息肉切除术病理检查结果的一致性,评价影响内镜下钳夹活检诊断与病理诊断胃息肉差异的影响因素。结果 145例患者中单发息肉124例(85.52%),多发息肉21例(14.48%)。共检出171枚息肉,内镜下钳夹活检诊断与电切术后病理学诊断结果一致的共119枚(69.59%),不一致的共52枚(30.41%)。两种诊断的病理学诊断结果的Kappa值为0.182,差异有统计学意义(P<0.05)。Logistic多因素分析结果显示,患者年龄≥60岁、息肉大小≥2.0 cm是影响内镜下钳夹活检与电切术后病理学诊断间组织学差异的独立影响因素。结论 内镜下钳夹活检诊断胃息肉病变性质及与病理诊断胃息肉结果存在不一致性,尤其对于年龄≥60岁、息肉大小≥2.0 cm的患者的差异更大,在临床诊断中应格外注意此类患者的胃息肉与癌变病灶并存现象。

Objective To analyze the pathological characteristics of gastric polyps diagnosed by endoscopic forceps biopsy, and explore the difference between the pathological diagnosis of gastric polyp specimens diagnosed by endoscopic forceps biopsy and the pathological diagnosis of gastric polyp specimens. Methods Clinical data of 145 patients who underwent endoscopic forceps biopsy diagnosis and endoscopic gastric polypectomy in the department of Gastroenterology of our hospital from February 2021 to February 2022 were retrospectively selected. We analyzed the pathological characteristics of gastric polyps diagnosed by endoscopic forceps biopsy, and compared the consistency with the pathological results of endoscopic gastric polypectomy. The influencing factors affecting the difference between endoscopic clamp biopsy and pathological diagnosis of gastric polyp were evaluated. Results A total of 124 cases(85.52%) had single polyp and 21 cases(14.48%) had multiple polyp in 145 patients. A total of 171 polyps were detected, 119 polyps were consistent with the pathological diagnosis after endoscopic clamp biopsy, accounting for 69.59%, and 52 polyps were inconsistent, accounting for 30.41%. The pathological diagnosis result Kappa value of the two diagnoses was 0.182, the difference was statistically significant(P<0.05). Logistic multivariate analysis showed that age≥60 years and polyp size≥2.0 cm were independent influencing factors influencing the histological difference between endoscopic clamp biopsy and electrosurgical diagnosis. Conclusion There is inconsistency between the nature of gastric polyp diagnosed by endoscopic clamp biopsy and the results of pathological diagnosis,especially for patients with age≥60 years and polyp size≥2.0 cm. Special attention should be paid to the coexistence of gastric polyps and cancerous lesions in such patients in clinical diagnosis.
