Villous tumors of the duodenum are rare, but treatment may be problematic because of their association with invasive adenocarcinoma. One case of villous tumor of the duodenum is described and 44 others reported cases are reviewed. Diagnosis may be made by radiographic barium contrast evaluation of the duodenum, especially with the addition of air contrast hypotonic studies and by fibro-optic endoscopy with biopsies. 32 p. cent of villous tumors of the duodenum are associated with adenocarcinoma. Local excision is the treatment of choice for benign lesions. Duodenectomy or pancreatico-duodenectomy are recommended for tumors which include invasive carcinoma.

Plain abdominal radiography in acute ulcerative colitis is essential to detect acute colonic complications, such as acute dilatation and free perforation. Sealed perforations may not be detected. Useful information can be gained as to the extent and severity of the mucosal lesions, but can be unreliable so that a contrast examination is required. The double contrast barium enema is more accurate than the single contrast study in revealing the early mucosal lesions of colitis. It is the examination of choice to show the extent and severity of disease, and is of considerable value in the differential diagnosis of colitis. In active colitis, the unprepared double contrast barium enema is recommended. The success of the examination relies on the absence of fecal residue adjacent to an active mucosa. The technique, uses, and limitations of this type of examination are described. In the long-term management of colitis, the role of radiology is to show the presence of extensive disease, which indicates an increased risk of malignancy. Lesions such as strictures or polyps may be found and are more likely to be benign than malignant, but confirmation often requires endoscopic biopsy. In the search for malignancy regular barium enema examination is not recommended, as this can only reveal an overt tumor, whereas premalignancy can be detected histologically from an endoscopic biopsy.

In 3 patients with carcinoma of the colon, lesions were seen as linear shadows on air-contrast barium enema studies. When the elevation of a lesion is slight or the tumor--mucosal interface is gently sloping, the tumor's proximal and distal edges may be ill-defined or disappear altogether. Thus only a linear shadow representing the interface between the tumor surface and air in the lumen appears. Other causes of these lines are also discussed.

In patients with Crohn's disease, early or localized lesions of the colon, termed 'focal granulomatous colitis', may give rise to small and often relatively inconspicuous nodular or tumor-like contour defects in conventional barium enema studies. This radiologic sign, first illustrated by Ettinger [7], has received scant attention in the literature. The present communication is intended to re-emphasize the radiologic appearances of focal granulomatous (Crohn's) colitis in conventional barium enema examinations, provide pathologic correlation, and illustrate by selected case reports the clinical significance of recognizing this particular radiologic abnormality.

The clinical and diagnostic features of a secondary type of achalasia of the esophagus are described in seven patients with various types of malignancies. Patients with secondary achalasia presented with dysphagia of short duration and marked weight loss; mean age was 64 years. Esophageal manometry showed features identical to those of idiopathic primary achalasia: aperistalsis, poor lower esophageal sphincter relaxation, and elevated sphincter pressure. Endoscopy and barium swallow showed evidence of a tumor in only two cases. Various types of malignancies may produce a secondary form of achalasia that has diagnostic features identical to those of primary achalasia and is best identified by its clinical presentation.

Prolapse of the gastric mucosa into the duodenum must be considered when a round soft tissue mass is seen in the right upper quadrant on scout abdominal film. Gastric prolapse may mimic tumor in the duodenum when the prolapse is large. Examination with barium meal is necessary to exclude prolapse of the gastric mucosa into the duodenum as a cause of epigastric pain and vomiting. Medical treatment is suggested for patients with mild symptoms, but patients with severe symptoms, repeated hemorrhage, anemia, severe intermittent epigastric pain and vomiting due to ball-valve syndrome should have operation.

The purpose of this presentation is to point out the importance of this new diagnosis and treatment method, recently incorporated. The studies were done with the Fibroscope F9-A with doble channel, equipped with an desection smear for polipectomies and an extracting forceps. The patients arrive with their intestine perfectly cleaned with classical methods. This detail is most important for the polipectomies. If the local conditions aren't the desired, presence of bowels or barium of an previous enema, we postpone both, examination and polipectomy, because those are causes of false diagnosis in the first case or eventual accidents in the second condition. Regarding this, we had an performing doing a biopsy in an stenosing neoplasm of the sigmoid colon. We believe it convenient to prevent this complication, to reduce the air pressure before performing the biopsy. Of the 160 patients examinated, 54 had no patology, 32 had polips and of this group 4 had multiple poliposis, 4 had association with diverticulosis and 3 associated with neoplasm. (4 were neoplasm, 10 stenosis without mucous lesions, 1 villous adenoma, 1 megacolon and 1 rectitis). We made 12 polipectomies, 10 with the conventional technique and 2 associated with surgery. We had no accidents and one of them was an early stage of colon cancer.

Tumors of the small intestine form only 1.5-8% of intestinal tumors. After a survey of localization, type of growth and tendency towards degeneration the most important clinical findings are described. The most common sign is high ileus. Barium swallow is recommended which, when all radiologic criteria are taken into account, may even permit identification of the type of tumor. Typical individual tumors are illustrated and described and differential diagnostic data are given. The potential and limits of angiography are discussed.

Villous tumors of the duodenum are extremely rare, only 41 cases having been described in the world literature. Modes of presentation were: gastrointestinal bleeding (11 cases); obstructive jaundice (9 cases); duodenal obstruction (10 cases); vague abdominal discomfort (8 cases) and as an incidental finding on barium study of the upper gastrointestinal tract (2 cases) or at autopsy (1 case). Twelve of the 42 cases were associated with invasive adenocarcinoma. These were confined to patients over 50 years of age. Benign tumors should be treated with local excision while in those harboring adenocarcinoma pancreaticoduodenectomy is the treatment of choice. Endoscopy and biopsy should assume a major role in attempting to obtain an accurate preoperative diagnosis. Caution is advised in that the superficial portions of the tumor may appear benign while deeper portions may contain invasive adenocarcinoma. An additional case with a bizarre presentation is described and the literature reviewed.

Appendiceal adenocarcinoma, a rare lesion, is difficult to diagnose preoperatively. The unusual combination of genitourinary symptoms, a fungating adenocarcinoma of the deeper layers of the bladder wall, and an abnormal barium enema resulted in what seems to be the first reported case to be diagnosed preoperatively. Preoperative radiotherapy and radical exenteration of the tumor with ileotransverse colectomy and ureteroileal cutaneous diversion were performed. The patient is well without evidence of recurrence two years later.
