Diverticular disease: imaging with post-double-contrast sigmoid flush.

In a prospective study, the effect of infusion of a low-density contrast material was evaluated as an adjunct to high-density, double-contrast imaging of the sigmoid colon. After double-contrast barium enema (DCBE) study, 52 consecutive patients with sigmoid diverticulosis received an additional 500-750-mL enema either with water or a 1.5% barium suspension for computed tomography. Rectosigmoid radiographs were evaluated for luminal distention, visualization of the interhaustral space, definition of diverticula, and interpretation of polypoid defects. While double-contrast views were excellent in 21% of patients, improvement in multiple factors by water or 1.5% barium flush resulted in improved sigmoid images in 65% and 75% of patients, respectively. Polyps were confirmed and artifactual defects confidently excluded. Sigmoid flush, particularly with low-density barium, is a simple adjunct to DCBE study that improves visualization of the diverticular sigmoid and increases interpretive confidence.

Colorectal carcinoma detected initially with barium enema examination: site distribution and implications.

The authors analyzed the site distribution of 122 consecutive cases of colorectal carcinoma in which a barium enema examination was available for review. The carcinoma was detected initially with barium enema studies in 82 cases (67%), sigmoidoscopy in 18 (15%), colonoscopy in 12 (10%), digital rectal examination in seven (6%), and computed tomography in three (3%). Thirty (37%) of the 82 cases found initially at barium examination were located in the cecum and ascending colon, which is a considerably higher proportion than that reported in studies based on cancer registry data or in surgical series. Thirty-eight (95%) of the 40 carcinomas first detected with other techniques were located distal to the hepatic flexure; 18 of those were identified initially with sigmoidoscopy. Because many distal carcinomas were first detected with nonradiologic techniques, an unusually high percentage of carcinomas in the cecum and ascending colon were found initially with barium enema studies. These findings suggest that barium enema evaluation of the right side of the colon needs to be at least as detailed as that of the rectum and sigmoid colon, areas that are increasingly assessed with sigmoidoscopy before barium enema studies are performed.

Sonography of appendiceal intussusception.

A case in which appendiceal intussusception was diagnosed preoperatively by sonography is described. The sonographic finding of multiple concentric hypoechoic and hyperechoic rings was confirmed at laparotomy to be due to appendiceal intussusception. Demonstration of the sonographic coiled spring sign in the right lower quadrant should raise the possibility of appendiceal intussusception. The differential diagnosis is discussed.

Double-contrast barium enema study: simple conversion to CO2.

The use of CO2 instead of room air for double-contrast barium enema (DCBE) studies has been shown to decrease discomfort after the study. An inexpensive system assembled from materials currently used to perform pneumocolon examinations is described, which simplifies conversion to CO2 use for the DCBE study. No changes in currently used pneumocolon techniques are necessary with the use of CO2.

Small bowel radiography: how, when, and why?

Since the advent of endoscopy for evaluating the upper and lower gastrointestinal (GI) tracts, it has become clear that only in the small bowel does barium radiography remain unchallenged. Regrettably, barium examination of the small bowel has traditionally been regarded by many radiologists as a study of minor importance. Small bowel follow-through techniques and enteroclysis methods differ in their diagnostic purpose, potential, and methods of performance. This review examines in detail the spectrum of barium examination techniques currently available for evaluating the small bowel. The benefits of enteroclysis in the majority of clinical situations requiring contrast examination of the small bowel are stressed. Radiologists play the crucial role in the diagnostic evaluation of the small bowel and should strive to refine and advance the accuracy of small bowel radiography.

Colorectal carcinoma: a radiologic and clinical review.

A profusion of imaging techniques is currently used for evaluating patients with suspected or known colorectal carcinoma. In most institutions, the combination of flexible sigmoidoscopy and a well-performed barium enema study should be retained as a more cost-effective, safe, and complete method of examination than colonoscopy. Endosonography appears to be promising for evaluating preoperatively the local extent of rectal carcinoma. CT is being challenged by MR imaging as the most sensitive modality for detecting liver metastases, but CT currently remains the technique of choice for evaluating recurrent disease and its extent. The diversity of available modalities will ensure that the radiologist remains at the forefront in the clinical investigation of colorectal carcinoma.

State-of-the-art barium examination in opportunistic esophagitis.

This report presents a comparison of state-of-the-art esophagography and endoscopy in the diagnosis of pathologically proven esophagitis. The modern multiphasic esophagogram is shown to have a sensitivity of 92% for the detection of opportunistic esophagitis in the immunocompromised patient. State-of-the-art esophagography provides a sensitive and inexpensive method for investigating patients in whom opportunistic esophagitis is suspected and for monitoring their response to therapy.

Aphthous lesions in nodular lymphoma of the colon.

The umbilicated nodules in colonic lymphoma may simulate aphthous ulcers of inflammatory or infectious colitides. Our report illustrates that in an immunosuppressed patient it may be difficult to distinguish on double contrast barium enema between the aphthous ulcers of opportunistic colitis and the umbilications of nodular colonic lymphoma.

Intubation routes for enteroclysis.

The transnasal and peroral intubation routes for enteroclysis examination are described. A survey of 22 patients who underwent enteroclysis by both approaches revealed an overwhelming preference for the transnasal route. Transnasal intubation for enteroclysis is rapidly performed with adequate catheter control and in most patients is associated with less discomfort compared with the peroral route.

Acquired jejunoileal diverticular disease: subject review.

Of 519 consecutive patients examined by enteroclysis, 12 (2.3%) were found to have acquired diverticula of the jejunum and ileum. All except one patient had multiple diverticula, most occurring in the jejunum. In only one patient could symptoms be ascribed to the abnormality. The combination of intraluminal distention and extrinsic abdominal compression provided by the enteroclysis technique appears to be the most reliable method for the demonstration of small-bowel diverticula. A discussion of the complications that may result from acquired jejunoileal diverticulosis and a review of the literature are presented.

Jejunal fold separation in adult celiac disease: relevance of enteroclysis.

The number of folds in the proximal jejunum was measured retrospectively in 25 studies of patients with adult celiac disease and 75 control subjects. The average number of folds per inch of proximal jejunum in the group with celiac disease was 2.88 (none to five), as against 4.88 (three to seven) in the controls. The difference was less pronounced in the distal ileum. A "mosaic pattern" was demonstrated in three patients. Positive radiologic evidence of celiac disease could be elicited in 76% of the patients' studies. Demonstration of five or more folds in the jejunum and/or three or fewer folds in the ileum would have been evidence against a diagnosis of celiac disease in 67 of the 75 controls. Indications for the use of radiography in celiac disease are reassessed.
