High-resolution gastrointestinal dynamics testing The SSI solid-state high-resolution gastrointestinal dynamics examination system introduced by our department has the advantages of accurate, comprehensive, intuitive and well tolerated by patients, which greatly improves the diagnostic level and efficacy assessment of gastrointestinal dynamics disorders and functional gastrointestinal diseases. 1.High-resolution esophageal manometry: It can obtain the data of esophageal peristalsis, upper and lower esophageal sphincter and relaxation rate intuitively; it is suitable for the judgment of GERD, cardia loss retardation, diffuse esophageal spasm, nutcracker esophagus, esophageal hiatal hernia, scleroderma esophagus and other diseases, and provide the efficacy assessment before and after drug treatment or esophageal surgery. 2.24-hour impedance-PH monitoring: It can detect gastroesophageal reflux of any acidity (acid reflux, weak acid reflux, non-acid reflux), clarify the nature of the reflux (gas, liquid or mixed type), the height reached by the reflux in the esophagus; assist in the diagnosis and treatment of GERD, especially for more in-depth diagnosis of refractory GERD. 3.High-resolution anorectal manometry: Assist in the diagnosis of chronic constipation, fecal incontinence, pelvic floor dysfunction, congenital megacolon and other diseases, and be used to assess the functional status of the anal sphincter after various anorectal surgeries. Together with biofeedback therapy, it provides effective treatment for functional bowel disorders. 4.Biofeedback: The electrical signals of rectal pressure and external anal sphincter are collected, and feedback is formed through video cartoon images and audio instructions to guide patients in the coordinated movement of rectum and anal sphincter, effectively improving patients’ functional defecation disorders and improving their quality of life. 5.High-definition anal 3D manometry: High-definition 3D kinetic image shows the pressure of the anal sphincter in all directions figuratively, clearly observes the state of the anal sphincter, improves the diagnostic accuracy and provides more basis for treatment. The adjustable window displays 3D bar chart, transverse section chart and pressure distribution chart to reflect the structure of anal sphincter in real time. 3D images precisely identify the site of sphincter damage or malfunction. Automatic analysis of symmetry, RAIR, and resting pressure information and automatic repair to compensate for pseudo-data generated by pelvic floor motion during testing.
