Abstract
OBJECTIVE Uvulopalatopharyngoplasty (UPPP) and genial and hyoid advancement (GHA) are surgical techniques for the treatment of obstructive sleep apnea. These techniques enlarge the oropharyngeal and hypopharyngeal airway, reducing collapse at these levels. This study evaluated the effect of these procedures on swallowing. METHODS Fifteen patients who had undergone UPPP and GHA were evaluated with a modified barium swallow to assess biomechanical changes in swallowing. Specifically, velopharyngeal insufficiency; changes in tongue-base movement, laryngeal elevation, and closure; epiglottic movement; and pharyngoesophageal opening were examined. A brief swallowing questionnaire was administered to assess for subjective changes in swallowing. RESULTS Nine of 15 patients demonstrated abnormal objective swallow, of whom 5 reported normal subjective swallowing. Six of 15 demonstrated normal objective swallowing. Of these, 5 reported subjective change. CONCLUSION UPPP with GHA may alter biomechanical events during deglutition. However, little correlation exists between subjective symptoms and objective findings. Further studies that include preoperative and postoperative modified barium swallows are needed to identify a cause-and-effect relationship.

Abstract
OBJECTIVE The authors determined which combination of computed tomography scans is most helpful for preoperative assessment of patients with liver tumors. SUMMARY BACKGROUND DATA Multi-institutional studies have shown that the most important prognostic factors for selection of patients with metastatic colorectal cancer considered for liver resection are: Dukes' stage of primary tumor, the number of hepatic metastases if greater than 3, the presence of extrahepatic cancer, and the ability to resect tumors with an adequate margin (> 1 cm.) Therefore the ability to predict the presence of extrahepatic disease and the number and location of hepatic tumors are important in these patients. METHODS One hundred and nine consecutive patients with evidence of hepatic tumors were evaluated by computed tomography with arterial portography (CTAP) and abdominal computed tomography after a 4-hour delay (CT-D). Results of these studies and conventional computed tomography (CT-C) were compared with findings at operation. RESULTS CTAP proved to be the most sensitive test for assessing distribution of intrahepatic disease. CT-D was no more sensitive than CT-C for the detection of hepatic or extrahepatic disease. CONCLUSIONS CT-C in concert with CTAP provides the most reasonable CT evaluation of patients considered for operation for the treatment of hepatic tumors.

Abstract
Variations in the pancreatic ductal anatomy result from abnormalities in embryological development of the pancreas from ventral and dorsal buds. We describe a case in which cholangiography demonstrated insertion of the common bile duct into an aberrant pancreatic duct. To our knowledge, this finding has not been previously reported in the literature.

Abstract
We have reported the case of a 58-year-old woman with nonspecific abdominal complaints in whom barium enema and subsequent colonoscopy showed a 3 cm lobulated adenocarcinoma within a villous adenoma arising from the appendiceal stump. Because such appendiceal malignancies have no specific clinical signs, symptoms, or radiologic features, preoperative diagnosis is extremely difficult, and colonoscopy may be required to clarify radiologically demonstrated irregularities.

Abstract
Radiology departments may inadvertently be contributing to their patient "no show" problems. This article continues the analysis of patients' failure to keep scheduled radiology appointments first described in "Patient 'No Shows'--A Costly Problem" (Radiology Management, 11:1) and illustrates "no-show" patterns in three examination groups in the Department of Radiology at the University of Texas Medical Branch, Galveston, Texas. The study shows a strong link between patients' failure to keep appointments and the length of time between scheduling and the performance of the examination.

Abstract
The occurrence of rectal diverticulosis is rare. We report the incidental finding of a large rectal diverticulum in a patient receiving an air-contrast barium enema. The presence of uncomplicated rectal diverticulosis is probably of little clinical significance. However, there can be associated complications such as inflammation and perforation, and potential confusion with rectal carcinoma.

Abstract
Over the past few years, a program was initiated at the author's institution to train radiologic technologists to perform the fluoroscopic aspect of gastrointestinal examinations. The program was undertaken in an attempt to improve patient flow through the division, as well as in response to the decreasing number of residents being accepted into the radiology program. The results with respect to diagnostic quality of examination, improved patient flow, and patient and resident acceptance have been satisfactory.

Abstract
The gastrointestinal tract lends itself quite well to digital imaging. Since fluoroscopy is already employed, the images can easily be obtained in digital format and several manufacturers have now developed systems for commercial use. Because of the type of pathology as well as the inherent subject contrast, it would appear the resolution requirements for digital imaging of the gastrointestinal tract are less than in other organ systems. The necessary resolution level is already technically available and feasible without significant cost. Digital imaging also holds promise of at least a modest reduction in radiation dose to the patient, as well as a reduction in costs, although these factors are operator dependent. However, digital imaging provides a latitude in performing the examination that is not available with screen-film systems. Finally, there is promise that by acquiring gastrointestinal images in digital format, manipulation of the images may help increase diagnostic accuracy by improving both technical and perceptive components of diagnosis. Not only will simple image manipulation be helpful but there is even potential for computer-assisted evaluation of gastrointestinal images.

Abstract
A prospective study was undertaken to evaluate whether reducing overhead (technician-performed) films in double-contrast colon examinations had any effect on diagnostic accuracy. Only 4 overhead films were obtained routinely: supine, both decubitus, and prone cross-table rectal views. A high detect rate was maintained, comparable to our accuracy when 7 or 8 overhead films were obtained. Our study confirms that with double-contrast colon examinations, the need for overhead films is diminished. A significant decrease in cost, radiation exposure, and examination time can be obtained. We continued to use this method without any noticeable decrease in diagnostic accuracy.

Abstract
Toxic dilatation of the colon represents the most serious complication of colonic inflammatory diseases. It is an acute transmural extension of severe inflammation resulting in decreased tissue cohesion and an increased tendency for bowel perforation. The process is characterized by dilatation and apparent radiologic thickening and nodularity of the bowel wall. Cases of toxic megacolon without dilatation occur infrequently.

Abstract
Many gastrointestinal diseases have a predilection for the terminal ileum. Retrograde ileography is a valuable technique for evaluating this region. However, this procedure necessitates reflux of barium (with or without air) into the terminal ileum. This does not often spontaneously occur during a barium enema study. The use of glucagon in double-contrast studies of the colon has been recommended for various reasons, one of which is to facilitate reflux of barium into the terminal ileum. This randomized, double-blind trial confirms that glucagon does promote reflux. Multiple regression analysis indicates that the independent variables of patient age, weight, and sex have little effect on the frequency of reflux. It is concluded that glucagon can facilitate examination of the distal small bowel during a double-contrast colon examination.

Abstract
During a recent regional screening program, 98 patients with a positive Hemoccult test were evaluated radiographically. Double-contrast barium enema (DCBE) detected all six carcinomas and 92% of 37 polyps. DCBE was also the most cost-effective procedure. Colonoscopy dramatically increased screening costs without providing evidence to support its use in all Hemoccult-positive patients. It is recommended that DCBE be the initial diagnostic test in Hemoccult-positive patients, to be supplemented in selected patients by flexible sigmoidoscopy or colonoscopy depending on the pathology evident on DCBE and on clinical circumstances.

Abstract
Four hundred fifty consecutive patients with dysphagia were evaluated radiologically over a 14-month period; 127 of these (28.2%) were also examined endoscopically. The most common abnormality seen was dysmotility (34%), followed by hiatal hernia, benign stricture, and esophagitis. Correlation with endoscopy was generally good. Radiologic study demonstrated all cases of esophageal malignancy; radiologic/endoscopic correlation was also strong in patients with moderate or severe esophagitis, though the radiologist had some difficulty detecting mild inflammation. Endoscopy failed to demonstrate some benign strictures. Radiologic study was relatively accurate in detecting significant organic disease; most motility disorders were not detected by endoscopy. For these reasons, as well as lower cost, increased convenience, and patient comfort, radiologic assessment is recommended as the primary method of evaluating patients with dysphagia.

Abstract
Secondary or "pseudo" achalasia of the esophagus can mimic idiopathic achalasia radiographically and can be difficult to diagnose. Typically, it is due to invasive carcinoma involving the gastroesophageal junction, usually gastric adenocarcinoma. Occasionally, an achalasialike condition can be produced by tumors not involving the gastroesophageal junction. We report 2 cases, 1 of lung carcinoma and the other of hepatoma, in which the patients had radiographic and endoscopic changes compatible with achalasia. However, the onset of symptoms was abrupt and the patients were elderly; these are unusual features for primary achalasia. There have been several other reports of nongastrointestinal neoplasms producing a clinical and radiographic picture similar to achalasia. Although there are several theories as to the cause, our cases would support the concept that direct tumor involvement of the gastroesophageal junction is not necessary to produce significant esophageal dysmotility.

Abstract
Eosinophilic gastroenteritis is an unusual condition of unknown cause in which there is eosinophilic infiltration of the gastrointestinal tract usually accompanied by a peripheral eosinophilia. Rarely, it can also involve the esophagus. Recently, the authors have encountered 3 cases of eosinophilic infiltration of the esophagus. All patients had a strong history of allergies. Two of our patients have had upper esophageal strictures, as have 2 other previously reported cases. This appears to be the most common manifestation. One patient had polypoid lesions of the esophagus as well as of the rest of the gastrointestinal tract. Motility disturbances may also be present. Although steroid treatment may be beneficial, the esophageal strictures usually require mechanical dilatation to relieve submucosal fibrosis. This entity should be considered in any patient who has an esophageal disorder in the presence of either a strong history of allergy or peripheral eosinophilia.

Abstract
During the past 2 years, we have encountered 14 patients whose onset of clinical symptoms of Crohn disease occurred after the age of 50, accounting for 14% of all Crohn disease patients studied in our department during this period. Most patients presented with diarrhea, abdominal pain, or perianal disease, and many also had anemia or rectal bleeding. The disease occurred slightly more often in the colon (n = 10), although many patients had terminal ileal disease (n = 7). The radiographic appearance was similar to that of Crohn disease in younger patients, with ulceration, fistula, and stricture formation. Occasionally, the disease mimics neoplasia or diverticulitis. Extraintestinal complications were also evident, with one patient each with renal calculi and ankylosing spondylitis. The occurrence of Crohn disease in the elderly is not uncommon, and a prompt diagnosis is important so that proper therapy can be initiated.

Abstract
Gastric polyps were found in 81 out of 4,692 consecutive radiological examinations (1.7%) and 103 out of 2,656 endoscopic examinations (3.9%) over a 19-month period. Polyps were more frequent in older patients and in women. Of 98 pathologically diagnosed lesions, 73 (74%) were hyperplastic and only two (2%) were adenomatous; most others were submucosal. Gastric polyps were rarely associated with carcinoma; only one patient had an area of severe dysplasia or carcinoma in situ, which was removed by polypectomy. The double-contrast technique had a high sensitivity and specificity in diagnosing gastric polyps. The location and number of lesions were relatively good indicators of pathology, but size and radiographic characteristics were not. The authors suggest that although radiology has a role in initial detection and screening, endoscopy should be the method of choice for further evaluation and follow-up. Histological identification is possible only with biopsy, and preferably polypectomy. The infrequent association with malignancy suggests that surgery is unnecessary in most cases.

Abstract
Several recent studies have shown a proximal shift in the distribution of colonic carcinoma compared to older studies. Because of the association between polyps and cancer, the authors evaluated the distribution of colonic polyps in 3,664 consecutive patients who had a colon examination over a period of 14 months. A total of 967 colorectal polyps were found in 633 patients. In all, 502 polyps (52%) were proximal to the rectosigmoid. Older patients had significantly more right-sided polyps and fewer rectosigmoid lesions. Large polyps occurred more frequently in the right colon, and this was also statistically significant. Gender has no effect on polyp distribution. The authors conclude that the importance of screening for polyps, particularly on the right side of the colon, increases with age.

Abstract
Five patients presented with dysphagia but did not have abnormal esophageal motility or morphology on the esophagram. Each was found to have a malignant gastric tumor which did not appear to involve the gastroesophageal junction, and this was confirmed surgically in 2 cases. In 2 patients, diagnosis was delayed as a result of failure to examine the stomach following a normal esophagram. In the absence of abnormal esophageal motility, changes involving the gastroesophageal junction, or cerebral metastases, it is postulated that the dysphagia represented a nonspecific regional response to functional obstruction of the upper gastrointestinal tract secondary to an infiltrating neoplasm of the stomach. The fact that the esophagram was normal emphasizes the possibility that gastric lesions in patients with dysphagia may be missed when only a routine esophagram is employed. The authors recommend that the stomach be examined when no apparent cause for dysphagia can be discerned above the gastroesophageal junction.

Abstract
Four cases of peptic ulcer penetrating the head of the pancreas were diagnosed by computed tomography (CT). Findings common to 3 cases included (a) an ulcer crater, (b) a sinus tract, and (c) enlargement of the head of the pancreas. Additional findings, not seen in all patients, included (d) edema involving the base of the ulcer and/or the adjacent bowel wall and (e) loss of fascial planes between the base of the ulcer and the head of the pancreas. Unlike other modalities, the inherent spatial resolution of CT allows a confident diagnosis of this important complication of peptic ulcer disease.

Abstract
A clinical data base system was developed that integrates gastrointestinal radiologic examinations, endoscopic studies, and pathologic diagnoses. An interrogative language is used, so that data input occurs by response to a series of relevant questions and answers that are constructed by the clinical staff without programmer support. Data are stored in a hierarchical, natural-language (noncoded) format, making them easily understandable by all clinical groups. Since the computer system is interactive, there are on-line capabilities for data input at various times as well as for instantaneous retrieval of all data on a given patient. Retrieval (search) of data uses Boolean logic, allowing for intercorrelative studies among radiology, endoscopy, and pathology. Data can then be isolated in files in which the computer can generate demographic and statistical data by use of a series of programs. Both data search and analysis can be accomplished without programming knowledge. Not only are research functions served by the system, but educational functions such as preparation of conferences and lectures, professional quality assurance, and resident teaching through follow-up and missed-case review can be performed.

Abstract
With the advent of fiberoptic endoscopy and modern radiographic techniques, the majority of detected polyps are less than 1 cm. During a seven-month period, we studied 140 patients who had radiographically demonstrated colonic polyps that were confirmed by pathologic study. Tissue specimens were obtained by proctoscopy, colonoscopy, or surgery. There were 222 polyps of which 144 (65%) were 1 cm or less in size, with the preponderance (80%) of these being adenomatous. Of the 82 polyps that ranged in size from 6-10 mm, 68 (83%) were adenomas, including one carcinoma and five villous adenomas. Forty-seven (72%) of the diminutive polyps (less than or equal to 5 mm) were adenomatous, including two with atypia. Our results correspond to those of several recent endoscopic studies, reporting that a small colonic polyp is most likely to be adenomatous, and that it possesses the potential for growth and malignant transformation. The detection of small polyps during barium enema examination is thus warranted, particularly in the proximal colon where the majority are adenomatous. The clinical management of polyps is becoming more aggressive, and the removal of even small lesions (less than or equal to 5 mm) is now performed if they are found incidentally during colonoscopy.

Abstract
The differentiation of colonic polyps and diverticula on the double-contrast barium enema is generally straightforward, using current diagnostic criteria. However, diverticula may be misinterpreted on the double-contrast barium enema as polyps when they appear uncommonly as filling defects within the barium pool. As a result of such erroneous interpretation, the patient may subsequently undergo costly and inconvenient repeat barium enema or colonoscopy. Carefully studied scout films, oblique views, compression spot images, and postevacuation films generally can differentiate these diverticula from polyps. The usual reason that a diverticulum assumes the appearance of a polyp is that it contains impacted stool.

We reviewed the radiographic findings in thirty patients with columnar-lined (Barrett's) esophageal mucosa. Gastroesophageal reflux was observed in 90%, hiatal hernia in 83%, stricture in 80% and esophageal ulceration in 33%. Superficial nodular mucosal changes were detected on 50% of the air contrast esophagrams. Prominence of this pattern may be associated with dysplastic or early malignant change. In addition, four conditions associated with secondary lower esophageal sphincter incompetence were identified in our patient group. These were scleroderma, previous myotomy for achalasia, previous gastric surgery and long-term indwelling nasogastric tubes.

Abstract
The air-contrast tube esophagram is performed by positioning a soft thin rubber catheter in the proximal esophagus. The patient drinks high density, low viscosity barium while the esophagus is insufflated with air through the tube. The procedure can usually be completed in five to eight minutes. In the majority of patients there is minimal discomfort. The advantage of the tube esophagram is the fact that it provides reliable, uniform full-column air distention.

Three patients who were 8 to 30 years status postmyotomy for achalasia were shown to develop Barrett's columnar metaplasia of the esophagus. In one instance, the patient had multiple areas of severe dysplasia to carcinoma in situ. There have been only a few reports in the world literature of Barrett's metaplasia occurring in postmyotomy achalasia patients. Our experience would indicate it may be a more common complication than previously appreciated. Also, a possible causal relationship between surgical intervention, Barrett's epithelium, and adenocarcinoma in achalasia is suggested.

Three cases of patients with esophageal involvement by scleroderma, chronic reflux esophagitis, and adenocarcinoma of the distal esophagus are presented. An underlying columnar metaplasia (Barrett esophagus) was identified in two patients and postulated in the third. It is believed that scleroderma patients with symptomatic chronic gastroesophageal reflux should be investigated for Barrett epithelium. If it is present, these patients should be followed and considered as having an increased risk for development of adenocarcinoma of the esophagus.
