Biliary tract abnormalities in patients with arteriohepatic dysplasia.

Arteriohepatic dysplasia is a congenital syndrome associated with life-long cholestasis. Because of symptoms suggesting extrahepatic biliary tract obstruction, we studied three patients with this syndrome by endoscopic retrograde cholangiopancreatogram (ERCP). All patients showed a decrease in the number of intrahepatic ducts. In addition, the intrahepatic ducts show attenuation with focal areas of dilatation. In one subject, this latter finding appeared to be a localized process. The extrahepatic ducts were also narrowed. One patient in this series was found to have gallstones and another cirrhosis. Although the relationship of these anomalies to the cholestasis seen in these patients is unclear, arteriohepatic dysplasis can be added to the list of processes associated with biliary tract abnormalities.

Tc-99m HIDA scintigraphy in segmental biliary obstruction.

Segmental biliary obstruction as a result of primary or secondary hepatic malignancy has been reported with increasing frequency. For two representative patients, the clinical and Tc-99m HIDA scintigraphic findings in segmental biliary obstruction are described. The presence of photon-deficient dilated bile ducts in one segment of the biliary tree is highly suggestive of localized biliary obstruction and should be considered in the patient with suspected or proven hepatic malignancy despite the absence of jaundice.

Roentgen manifestations of carcinoma in the gastric remnant.

Awareness of the increased incidence of carcinoma in the gastric remnant has not been accompanied by improved diagnosis or prolonged survival. The long latent period prior to development of tumor, the insidious nature of symptoms, and the anatomical distortion produced by surgery contribute to the difficulty in detection of these lesions. The radiological spectrum of carcinoma of the gastric remnant is discussed and both characteristic and unique radiographic features are illustrated.

Myxedema megacolon.

The radiological findings on barium enema examination of 239 patients with thyroid deficiency (192 hypothyroid and 47 myxedematous) were reviewed. A new radiologic finding of transverse ridging superimposed on megacolon is described in myxedema and an explanation for this finding is postulated. The colonic findings associated with thyroid deficiency are presented.

Cholangitis in a child due to biliary tract anomalies.

A 29-month-old child with persistent cholangitis and steatorrhea complicating congenital hepatic fibrosis underwent radiographic evaluation of the biliary tree. Communicating intrahepatic cavernous ectasias were demonstrated by percutaneous transhepatic cholangiography, a procedure deemed safe in children of this age group. Unlike most patients with cholangitis, he had documented steatorrhea and growth failure which resolved following successful treatment with trimethoprim-sulfamethoxazole. Bacteriologic diagnosis was made by direct culture of liver tissue combined with duodenal intubation.

Aphthoid ulcerations in gastric candidiasis.

Tiny aphthoid erosions appear to represent the earliest detectable radiographic change in gastric candidiasis. In this report, the radiographic appearance of these lesions is correlated with gross and microscopic pathologic anatomy, and the progression of these ulcerations to deeper linear furrows is illustrated. It is hoped that the detection of the gastric candidiasis at this early stage will hasten therapy, and thus decrease the risk of fulminant infection in the immunocompromised host.

Liquefactive necrosis of the pancreas: the pancreatic sac.

The authors describe an unusual form of pancreatic necrosis in which the excavated necrotic core is surrounded by a shell of tissue and forms a sac which generally conforms to the axis and contour of the pancreas. This debris-containing sac could be misinterpreted on ultrasound and CT and is best defined by direct injection into the pancreatic duct.

Diagnosis of annular pancreas with endoscopic retrograde cholangiopancreatography.

Two patients with annular pancreas are described. The diagnosis was established unequivocally with endoscopic retrograde cholangiopancreatography before operation. In both patients there was pancreatitis of the annular pancreas. The first patient also had congenital absence of the ventral pancreas and pancreatic insufficiency. The second patient subsequently developed gastric outlet obstruction. The literature is reviewed.

Transient hypertrophic gastropathy in childhood: a protein-losing gastropathy distinct from Menetrier's disease.

Transient hypertrophic gastropathy in a child with similarity of radiographic and clinical features to Menetrier's disease is described. Distinction from Menetrier's disease is emphasized as the condition is characterized by abrupt onset, short duration, eosinophila and good prognosis. The association with hypersensitivity as a possible etiology is more suggestive in this condition. The radiographic changes will often provide the first clue to this condition and rapid reversal of the gastric changes is diagnostic.

Drug-induced gastrointestinal disease.

The gastrointestinal tract is a common target for adverse drug reactions. The resultant changes are often nonspecific (e.g., mucosal ulceration, intestinal infarction, motility disturbance) and in many cases no radiographically detectable lesion may occur. A comprehensive review of the reported drug-induced disorders of the digestive organs is herein presented and their radiographic manifestations are described.

Iatrogenic problems following gastric surgery.

It is difficult to truly define iatrogenic complications in the postsurgical state in that the surgery is a condition originated by physician intervention and thus any problems that occur may be technically considered as physician created. In this article we attempt to demonstrate problems that occur both due to technical errors and the choice of operative procedure. In addition, unusual postsurgical anatomy is illustrated with the hope of avoiding further iatrogenic problems from lack of recognition.

Cervical Thorotrast granuloma: an iatrogenic cause of dysphagia.

Thorotrast granuloma of the neck is an extensive benign connective tissue overgrowth secondary to localized extravasation of contrast. This can present with dysphagia secondary to mass effect or motor disorder of swallowing related to demyelinization of the ninth through twelfth cranial nerves. The radiographic appearance is characteristic in both location and density.

Hemobilia following percutaneous transhepatic cholangiography.

Percutaneous transhepatic cholangiography is a safe, effective diagnostic procedure for use in evaluating the jaundiced patient. As is the case with most invasive diagnostic procedures there is a risk: an overall mortality rate of 0.5% and morbidity rate of 3-10%. Fortunately hemobilia is an uncommon complication, encountered only four times in our series of 102 percutaneous cholangiograms. In every case of hemobilia the clotting parameters were normal. The one factor common to each case was distal obstruction of the extra hepatic bile ducts. However, this one factor may play an important role in the etiology and therapy of post cholangiographic hemobilia. The hemorrhage subsided spontaneously in every case following surgical decompression of the bile ducts and there was no further active bleeding postoperatively. The possible explanation for the cause of bleeding and the fact that it subsided following demcompression of the bile ducts is discussed. All four patients survived this complication and in the 102 patients there were no deaths attributable to percutaneous transhepatic cholangiography.

Aperistalsis and esophagitis.

Aperistalsis of the esophagus was demonstrated in six patients with esophagitis. This was observed in reflux, caustic, and infectious esophagitis, and has occurred both as a transient phenomenon with no further sequelae, and as the initial manifestation of involvement in patients who subsequently suffered stricture. Based on biopsy and autopsy specimens in two cases, a possible mechanism of aperistalsis related to the damage to neurons in Auerbach's plexus is postulated. The presence of aperistalsis has been the first significant clue to esophageal inflammation in several cases.

Sequelae of stomach surgery.

Gastric surgery has undergone continuous evolution since the 19th century. At present it is a highly sophisticated technique which provides symptomatic relief for the vast majority of patients operated upon for peptic ulcer disease. Although the overall incidence of complications has decreased, a variety of complications continues to occur and radiological examination plays a critical role in their detection, evaluation, and management. Knowledge of the variations in surgical terminology and commonly used eponyms provides the basic framework for discussion. Familiarity with the radiological appearance of the normal postoperative stomach together with an understanding of its physiology are essential prerequisites to the recognition of possible complications. Operative techniques may result in a radiographic appearance which simulates disease. Conditions as diverse as bezoars, afferent and efferent loop problems, marginal ulceration, anastomotic leakage, prolapse, and intussuception may all be characterized by distinct and highly specific radiographic changes. Physiologic problems such as dumping and malabsorption may also reflect their presence by X-ray changes. The radiographic features in a large number of surgical complications are discussed and illustrated. The importance of the radiographic examination in the postsurgical stomach is emphasized.
