1
Alternatively, further assessment by MRI or flexible endoscopic ultrasound may be considered.
2
Preoperative findings of endoscopic ultrasound were classified according to TNM staging.
3
Staging consisted in colonoscopy, thoracic and abdominal CT, pelvic MRI and endoscopic ultrasound.
4
Moreover, elongated echogenic material with a central hypoechogenic area was seen on endoscopic ultrasound.
5
The accuracy of endoscopic ultrasound to predict response was determined.
1
The most frequent causes of misdiagnoses by endosonography were microscopic tumor invasion and peritumorous inflammatory changes.
2
Sensitivity and specificity for T and N staging were equal or superior in the endosonography group.
3
From January 1988, 424 patients with rectal cancer were examined by endosonography.
4
Compiled data in the literature for MRI staging of rectal cancer show results similar to those with endosonography.
5
Therefore we see no indication for preoperative rectal staging methods other than endosonography unless the latter examination is technically impossible.
6
Background: No study on bioclinical criteria predicting a biliary origin for acute pancreatitis has included endosonography as a reference examination.
7
In 20 patients endosonography was followed by ERCP, and in 19 endoscopic drainage was attempted.
8
Anal endosonography has been performed in 22 patients with fistula in ano and perianal sepsis and compared with the operative findings.
9
However, its application in the posttreatment setting remains problematic, since concordance rates between endosonography and histology findings during follow-up seem to vary substantially.
10
Methods: Anal endosonography was performed in 20 patients with solitary rectal ulcer syndrome and IAS thickness defined as normal or abnormal depending on age.
11
Regarding the 30 internal openings located in the vagina during surgery, the positive predictive value of preoperative endosonography was 93%.
12
Endosonography was the sole method establishing the diagnosis of biliary pancreatitis in 15% of patients.
13
Conclusion: Endosonography provides essential information prior to endoscopic drainage of pseudocysts, leading to a change in therapy in one third of patients.
14
Endosonography changed management in 37.5% of the patients.
15
Results: Endosonography failed to identify a pseudocyst in 3 patients and in 2 patients the lesion was inconsistent with a pseudocyst.
16
The most frequent causes of misdiagnoses by endosonography were microscopic tumor invasion and peritumorous inflammatory changes.
