Significance of diffuse granularity and nodularity of the esophageal mucosa at double-contrast radiography.

Out of 5000 consecutive double-contrast examinations of the esophagus, 50 cases presented a diffuse finely granular or nodular appearance of the mucosa. Endoscopy was subsequently performed in 38 cases and biopsy in the majority of these. In 23 of the 38 verified cases the diagnosis was reflux esophagitis. In the other 15 cases the diagnoses were: candidal esophagitis (4), leukoplakia (2), glycogenic acanthosis (1), and diffuse leiomyomatosis (1). A normal mucosa was demonstrated in 7 cases. Our study indicates that a radiologically granular or nodular appearance of the esophageal mucosa often indicates reflux esophagitis and less commonly identifies diffuse lesions of variable origin.

Reflux esophagitis: radiologic-endoscopic correlation in 39 symptomatic cases.

Thirty-nine consecutive patients with symptoms suggestive of reflux esophagitis underwent a double contrast upper gastrointestinal series and subsequently had endoscopy with biopsy. In a control group of 164 consecutive patients without symptoms of esophagitis a double contrast examination was done with the same method. We have found a significant increase of the diameter of the esophagus in its distal or cardiac segment (IDCE) in patients with esophagitis of Grades 1 and 2 when compared with the control group (p less than 0.001). Radiology was found to have correctly diagnosed 35 of the 39 cases (89.7%) and the majority of the patients had endoscopic signs of mild esophagitis.

Small benign tumors of the esophagus: radiological diagnosis with double-contrast examination.

Benign tumors of the esophagus are rare. So far radiological examination has been useful in the diagnosis of fairly large benign tumors. In 4100 consecutive double-contrast studies we have found 22 incidental cases of protruded lesions of the esophagus with the appearance of submucosal tumor (8 cases) or polyp of the mucosa (14 cases). The lesions were small: 14 were less than 1 cm and 8 were between 1 and 3 cm. The histological data showed leiomyoma in the submucosal tumors and squamous papillomas in the polyps of the mucosa. A noteworthy feature is the unusual frequency of small squamous papillomas detected. The radiological diagnosis of benign tumors of the esophagus cannot be confined to large tumors in symptomatic patients but may include the accidental detection of small tumors. These call for histological verification and possibly endoscopic removal.

Radiologic diagnosis of early gastric cancer by routine double-contrast examination.

In 4538 double-contrast examinations of the upper gastrointestinal tract, 8 early gastric cancers (EGCs) were prospectively diagnosed before endoscopy. Four others were false negative cases, but retrospective analysis led to identification of the lesion in 3. The rate of EGC in radiologically diagnosed and verified cancers was found to be 10.6%. Gastric polyp rarely corresponded to EGC, whereas gastric ulcer more frequently corresponded to an EGC. Five of 12 EGCs were multifocal, with 21 satellite foci of carcinoma, of which 3 were probably radiologically identifiable as varioliform erosions. Routine double-contrast study appears valuable for detecting EGC, but the rate of false negative cases indicates that integration of radiologic, endoscopic, and cytologic data as well as accurate histopathologic study of the surgical specimen are needed to diagnose and characterize early gastric carcinoma.

[Methodology in gastrointestinal radiology. Suggestion for standards and preliminary results].

The Marche SIRMN group tried to set up standard of some common radiological examinations (cholecystography, single and double contrast examination of the upper gastro-intestinal tract, and single and double contrast enema). Scientific and professional reasons led to this work. Twenty-five radiologists from thirteen centers in the Marche region cooperated on it. Some differences between the plan and the real performance of the standard radiological examinations as well as between technical and methodological performance came out. Eventually preliminary and partial data about the cost of the procedures and the final diagnostic result were obtained.

[The diagnosis of hepatic metastases is a frequent problem in clinical practice (author's transl)].

In 131 verified cases with known primitive tumor, the diagnostic accuracy of the echotomography resulted in 84% (sensitivity 89%; specificity 76%). Technical insufficiency of the echotomography did not define the diagnosis in 8% of the patients. The evidence of solid lesions in both lobes of the liver and the involvement of the inferior vena cava are the criteria for inoperability and selection for angiographic test. The diagnostic value of the echotomography was low in cases where the primitive tumour was not identified because of the non specificity of the echo-structure of the solid intrahepatic lesions. Angiography is essential when a liver resection is planed.

[Multi-institution, multidisciplinary radiology and endoscopy trial of the diagnostic accuracy of the double contrast examination of the stomach surface].

In 12 X-ray and gastroenterology departments 1570 patients, clinically suspected to have a gastric pathology, have been examined by double contrast (surface) examination of the stomach followed by gastroscopy. Diagnostic accuracy was 93% in respect of endoscopic data, assumed correct by hypothesis. On the basis of a cost and benefit evaluation, made according to the well known criteria, a wider routine use of the double contrast technique is proposed.

[Routine double contrast examination of the stomach: results and considerations on personal experience (author's transl)].

The results are presented on the double contrast investigation of the stomach performed during routine hospital activity. Purposes of the work are to evaluate the diagnostic accuracy of the method and to suggest the location of the diagnostic investigation. 602 consecutive patients were examined and 188 out of these underwent endoscopy. The diagnostic accuracy of the method was evaluated at gastroscopic control. Moreover the cost of the method was considered, in order to evaluate the possible routine application of the method in the hospitals.

[Problems of gastrointestinal angiography].

The subject of abdominal angiography is discussed, for informational rather than technical reasons, on the basis of seven years personal experience. The method used to prepare the patient for angiography and emergency treatment of the various episodes of reaction to the contrast medium or of complications of arterial catheterism are illustrated and some of the most significant aspects of abdominal angiographic symptomatology described.
