[Cholesterol crystals and biliary lithiasis. Importance of the study of bile collected by duodenal intubation].

Cholesterol crystallization in a necessary step in the formation of cholesterol gallstones. Our purpose was to study the relationship between the presence of biliary cholesterol crystals and radiolucent gallstones. Bile was obtained by duodenal intubation from 60 subjects free of hepatic disease: 40 patients had radiolucent gallstones and in the remaining 20 subjects no gallstones could be found either by oral cholecystography or by ultrasound examination. In each patient a bile sample was used to search for cholesterol crystals; in another sample, biliary cholesterol, phospholipids and bile acids were measured to calculate the lithogenic index. Among the 44 subjects with lithogenic bile, 34 had radiolucent gallstones. Twenty-two out of the 60 patients had both cholesterol crystals and radiolucent gallstones; 21 subjects out of the 22 had lithogenic bile. In patients with frequent biliary colic or subacute pancreatitis without visible gallstones, finding cholesterol crystals in bile might suggest medical or surgical specific treatment.

[Granulomatous colitis presenting as ischemic colitis].

The authors describe a case of granulomatous colitis mimicking a non gangrenous ischemic colitis. The radiological features are thumbprinting, ulcerations, then stenosis and sacculation. The resected specimen reveal some granuloma without necrosa.

[The double contrast small bowel enema in Crohn's disease. 32 examinations (author's transl)].

The authors have performed 150 double contrast small bowel enema. The results of 32 radiological examinations in Crohn's disease are reported. Four elementary alterations of the mucosal pattern can be described:--folding modifications,--mucosal defects,--different ulcers,--association between defects and ulcers drawing the classic "cobblestone" pattern. The transmural lesion is evident by fistules, strings, dilatations and mesenteric retractions. The conventionnal radiologic examination of the small bowel is satisfactory to show the manifestations of transmural lesion; but the double contrast enema is clearly more performing to characteristic mucosal lesions. So it appears indispensable to use this method for exploration of every Crohn's disease, to complete the conventionnal repletion enema.

[Radiological features of non-gangrenous ischaemic colitis (author's transl)].

The authors have performed barium enema in 22 cases of non gangrenous ischaemic colitis. The diagnosis was established on the clinical, endoscopic and radiological data. The barium enema's radiological features and their evolution are described in particular thumbprinting, ulcerations, stenosis and sacculations. All these radiological signs were confirmed by endoscopic investigation or pathological examination. Abdominal angiography are carried out in 10 cases. The preferential site of the lesions is the descending colon. The differential diagnosis with other colitis are discussed and the diagnosis is easier when the barium enema is performed soon.

[An intramural hematoma of the small intestine, during anticoagulant therapy: radiological course. Concerning one case].

The authors present a case of intramural hematoma of the small intestines during anticoagulant treatment. With reference to this case, they study the frequency, etiopathogenesis and anatomy of this hematoma and particularly look at the radiological manifestations. In this respect they distinguish three stages in the evolution. The first, when the straight X-ray of the abdomen and barium followthrough demonstrate an axial stenosis of the small intestines with dilation of the proximal loops; the second (between the 7th and 20th days) when the loop affected by the hematoma takes on a characteristic "palissade" or "spring" -like sausage appearance; finally the third (after the 3rd week), when only thickening of the haustrations persists with progressive return to normal. The radiological diagnosis is discussed, not only with intramural hematomas of the small intestines of other etiologies (traumatic, during pancreatitis, during disorders in hemostatis), but also with conditions giving rise to similar radiological pictures: malabsorption, inflammatory conditions, etc.

[Radiological double contrast examination in Crohn's colitis. A report about 115 cases (author's transl)].

The authors had examined by double contrast barium enema in 115 cases of Crohn's ileo-colitis. They described the radiological double contrast features. The "early lesions" are always surrounded by a healthy-looking mucosa. The advanced lesions are segmentary: shallow limited ulcers, shallow confluent ulcers, cobblestone pattern and nodular pattern. Several types of lesions may appear in the same patient. The distribution of the lesions is asymmetrical with skip areas and gradual size of the lesions. The parietal lesions are well demonstrated by double contrast, especially the sacculations. Our radiological findings are confirmed by endoscopical features and excised specimens in 100 cases. A double contrast barium enema is necessary to well described the lesions especially the "early lesions" which are important for differential diagnostic, with ulcerative colitis, for surgical treatment in evaluating the extend of the disease and possibly even for prognosis in this disease.
