Abstract

To explore the clinical application value of narrow band imaging (NBI) in the early screening of colorectal cancer. 200 patients were selected as the research objects, and were divided into test group and control group by the randomization method, within 100 cases in each group. The patients in the test group were examined by NBI, while the patients in the control group were examined by ordinary endoscopy, and then the lesion detection rate, image definition and pathological examination results of the two groups were compared. After the patients in the test group received NBI examination, the lesion detection rate, image definition and lesion detection coincidence rate were significantly higher than those of the control group, and the comparative difference between the two groups was statistically significant (P < 0.05). NBI examination of colorectal mucosa can clearly show the pit pattern and the morphological structure of capillaries of the early colorectal cancer and its precancerous lesions, thus effectively improving the diagnosis rate of early colorectal cancer and its precancerous lesions, playing a good clinical application value in the early screening of colorectal cancer, and guiding the later treatment, so it is suitable for clinical promotion.

Highlights

Colorectal cancer is a clinically common malignant tumor disease, including colon cancer and rectal cancer, and due to its poor prognosis, it has higher morbidity and mortality (Xu et al, 2018)
narrow band imaging (NBI) does not need staining during the endoscopy, which can better show the micro morphological structure of the mucosal surface of the digestive tract, and can find lesions that cannot be displayed under ordinary endoscopy, greatly improving the detection rate of colorectal lesions, and playing an important role in the early screening of colorectal cancer
The clinical pathogenesis of colorectal cancer has not yet been clarified, but in-depth researches have been conducted on the pathogenetic factors, and it is clinically believed that the pathogenesis of colorectal cancer is closely related to living habits, environment, diet, and genetic factors (Han et al, 2016)

Summary

Introduction

Colorectal cancer is a clinically common malignant tumor disease, including colon cancer and rectal cancer, and due to its poor prognosis, it has higher morbidity and mortality (Xu et al, 2018). At present, the most clinically important problem that most urgently needs to be resolved is to actively find ways to improve the early diagnosis rate of colorectal cancer, reducing the mortality of patients with colorectal cancer, improving the prognosis of patients with colorectal cancer, and improving the quality of life of the patients. At this stage, the clinical diagnosis of colorectal cancer is mainly performed by ordinary colonoscopy, but this examination method often encounters missed diagnosis due to the inability to diagnose tiny polyps or flat lesions without distinctive feature, delaying the treatment of the patients (Jiang & Yan, 2017).
