ABSTRACT
OBJECTIVES:
To describe a facilitated procedure of colorectal filling contrast ultrasonography (CFCUS) and explore its value in the diagnosis of pediatric juvenile polyps.METHODS:
One hundred and eleven children with clinical signs of colorectal polyps admitted to our hospital between May 2018 and May 2021 were retrospectively reviewed. All children underwent conventional transabdominal ultrasonography (CTUS) and CFCUS prior to undergoing colonoscopy. Pathologic findings were used as the gold standard. Chi-squared tests and Mann-Whitney U tests were used for the statistical analysis.RESULTS:
Forty-five children with fifty-two colorectal polyps were confirmed via pathological examination. The sensitivity, specificity, positive predictive value, and negative predictive value of CFCUS vs. CTUS were 92.3% versus 80.7%, 100% versus 100%, 100% versus 100%, and 93.3% versus 84.8%, respectively. The missed polyps were significantly smaller than the polyps detected in diameter (7.50 ± 2.12 mm vs. 19.62 ± 7.89 mm, p < 0.0001) by CTUS. A significant difference between CTUS and CFCUS was observed in the detection rate of polyps with a diameter < 1 cm (p = 0.031) and pedicles (p < 0.001). The kappa values for the assessment of Yamada's classification between CTUS and colonoscopy and CFCUS and colonoscopy were 0.51 and 0.84, respectively. Moreover, CFCUS incidentally revealed a punctate hyperechoic area on the surface of colonic polyps in six cases, which may be suggestive of a correlation with erosion and bleeding findings.CONCLUSION:
CFCUS can increase the detection rate of polyps and pedicles, especially polyps with diameters <1 cm, and accurately evaluate Yamada's classification, providing useful preoperative information for colonoscopy.Palavras-chave
