ABSTRACT: Objective: To explore the clinical diagnostic value of transperineal volume ultrasound combined with two-dimensional high-frequency ultrasound for anal fistula. Methods: A total of 52 patients with anal fistula admitted to the Affiliated Hospital of Shaanxi University of Traditional Chinese Medicine from December 2017 to July 2018 were selected. They were all undergoing transperineal 3D volume ultrasound combined with 2D high-frequency ultrasound examination, and the diagnosis results were analyzed. The results of ultrasonography and surgical pathology were compared. Results: Among 52 patients, 3D volume ultrasound combined with 2D high-frequency ultrasound were used to diagnose 32 cases of anal fistula intersphincteric type, 14 cases of transsphincter type, 5 cases of supra-sphincter type, and 1 case of extra-sphincter type. T supervisor classification accuracy rate is 90%. The detection rate of branch pipes was 92%, and the compliance rate of internal fistula was 95%. Two-dimensional high-frequency ultrasound was used to diagnose 34 cases of anal fistula intersphincteric type, 14 cases of transsphincter type, 4 cases of supra-sphincter type, and 0 cases of extra-sphincter type. The detection rate of branch canals was 42%, and the accuracy of type classification was 90%. The coincidence rate was 95%. There was a statistically significant difference in the detection rate of the anal fistula branch and the coincidence rate of the internal fistula between the two methods (both P Conclusion: 1) The overall coincidence rate of three-dimensional volumetric ultrasound combined with two-dimensional high-frequency ultrasound in the diagnosis of anal fistula is high; 2) Three-dimensional volumetric ultrasound technology has great application prospects in infants and anal fistulas.
