Clinical examination,
endosonography, and MR imaging in preoper-ative assessment of fistula in ano: comparison with outcome-based reference standard.
Anal
endosonography is the gold standard in imaging the sphincters, and has superseded conventional electromyography mapping in the diagnosis of anal sphincter defects.
Despite
endosonography being an invasive technique, it is quite sensitive for the evaluation of pancreatic pathologies such as chronic pancreatitis (29).
The participants underwent anal
endosonography and anal manometry in the third trimester of pregnancy, and 24 hours following delivery.
Endosonography is the most sensitive method for evaluating local lymph node invasion.
Furthermore, pelvic computed tomography (CT), transrectal
endosonography, USG or magnetic resonance imaging (MRI) are useful for showing the relationship between the environment and the contents of the cyst tissue.
The European Society of Thoracic Surgeons (ESTS) guidelines recommend preoperative surgical staging in case of a negative
endosonography because probability of having mediastinal nodal involvement for any individual patient with a negative
endosonography result is 13%-15%.
Patients were selected consecutively from
endosonography examinations performed for upper gastrointestinal subepithelial lesions and pancreas evaluation.
Endosonography confirmed these findings and additionally showed tumor infiltration into the stomach.
