Abstract:
Objective To explore the application value of Three-Dimensional rectal cavity ultrasound combined with contrast agent imaging in necrotizing fasciitis of the anal region.Methods Before surgery,standard three-dimensional rectal cavity ultrasound examinations(referred to as the conventional group)and contrast agent imaging examinations(referred to as the imaging group)were conducted for 40 patients clinically diagnosed with anal region necrotizing fasciitis.Separate observations were made for the primary lesion,as well as for the depth and superficial necrosis of the fascia,and injuries to the anal sphincter muscle.Comparative analysis with surgical results was undertaken to assess the diagnostic sensitivity of both the conventional and imaging groups.Results In comparing the conventional group with the imaging group,the rates of primary lesion visibility rose significantly from 70%to 97.5%,deep fascial necrosis visibility increased from 50%to 88.8%,superficial fascia visibility improved from 70%to 100%,and the visibility of anal sphincter muscle injury escalated from 62.5%to 97.2%,all demonstrating statistical significance at P<0.05.Conclusions Three-dimensional rectal cavity ultrasound combined with contrast agent imaging exhibits significantly enhanced accuracy in identifying primary lesions associated with perianal necrotizing fasciitis,as well as the necrosis affecting deep and superficial fascia,in contrast to conventional three-dimensional rectal cavity ultrasound.This advancement offers more precise guidance for clinicians in devising surgical plans,thereby augmenting the success rate of surgical interventions.
