Abstract:
Objective:To investigate the diagnostic values of ultrasound-guided puncture biopsy of intra rectal cavity and colonoscopy biopsy for rectal and anal canal tumors.Methods:A total of 100 patients with rectal tumors,who admitted to Beijing Rectum Hospital from March 2021 to March 2023,were selected.All patients completed three-dimensional(3D)ultrasound examination of intra rectal cavity,and all of them adopted both colonoscopy biopsy and ultrasound-guided puncture biopsy of intra rectal cavity to obtain tissue samples.Postoperative pathological results were used as the"gold standard"to compare the diagnostic accuracy,pain index,amount of blood loss and examination time of two kinds of modes in sampling.The Kappa test was adopted to analyze the consistency between two kinds of examination methods and postoperatively pathological staging.Results:The sensitivity,specificity and accuracy rate of pathological diagnosis with colonoscopy biopsy were respectively 90.74%,82.61%and 87.00%in diagnosing the benign and malignant rectal tumor.The sensitivity,specificity and accuracy rate of ultrasound-guided puncture biopsy of intra rectal cavity were respectively 98.25%,97.67%and 98.00%in diagnosing the benign and malignant rectal tumor.The diagnostic accuracy rate of ultrasound-guided puncture biopsy of intra rectal cavity was higher than that of colonoscopy biopsy,and the difference was statistically significant(x2=4.672,P<0.05).Kappa test analysis indicated that there was moderate consistency between colonoscopy biopsy and pathological staging in diagnosing rectal cancer(Kappa=0.66),and there was high consistency between ultrasound-guided puncture biopsy of intra rectal cavity and pathological staging in diagnosing that(Kappa=0.77).Conclusion:Both colonoscopy biopsy and ultrasound-guided puncture biopsy of intra rectal cavity have highly diagnostic accuracy rate for rectal tumors.However,ultrasound-guided puncture biopsy of intra rectal cavity has obvious advantages for the biopsy of submucosal rectal tumors and anal canal tumors,and it has minimally invasive and cost-effective advantages,which has higher clinical application value.
