Abstract
Radiologically guided balloon catheters were used to dilate 94 gastrointestinal strictures in 92 patients over a 6-year period. Fifty strictures were esophageal and 44 nonesophageal (22 gastroenterostomies, 11 antral-pyloric strictures, four colorectal strictures, four enteroenterostomies, and three miscellaneous strictures). Factors influencing the success of stricture intubation included patient age, stricture location (esophageal vs. nonesophageal and proximal vs. distal esophageal), and association with a surgical anastomosis. Malignancy was associated with greater postdilation irregularity and a smaller increase in stricture diameter, as measured radiographically. Procedural failures occurred in 8% of cases (2% of esophageal and 30% of nonesophageal lesions). Two small, asymptomatic mucosal tears were seen after dilation (one esophageal and one colonic); no other procedural complications occurred. Following successful dilation, 16 patients (17%; six with esophageal and ten with non-esophageal strictures) had recurrence of symptoms during short-term (30-day) follow-up.

Abstract
Balloon dilation catheters were used to treat 94 gastrointestinal strictures in 92 patients over a 6-year period. Long-term follow-up data were obtained for 80 of these patients, with a mean follow-up period of 389 days. Overall, of the patients who underwent a successful dilation procedure, 83% remained symptom free after 1 year, and 69% after 2 years. The location of the stricture did not significantly influence the long-term outcome, nor did procedure characteristics, aside from primary technical failure. Both patients with malignant strictures and those whose strictures were associated with an anastomosis were more likely than other patients to have recurrent symptoms.

Abstract
A retrospective study of 55 patients with a benign esophageal stricture showed that in 11 patients (20%) the cause was a drug-induced lesion due to potassium chloride (3), tetracyclines (3), aspirin (2), vitamin C (1), phenytoin (1), and quinidine (1). Five of the 11 patients would have been diagnosed as having a reflux etiology of their stricture if 24-hour esophageal pH monitoring was not performed. Six patients responded to dilatation and five patients required resection or bypass. A prospective study of 18 asymptomatic volunteers showed a high incidence of esophageal lodgment of a radiolabeled medicinal capsule, with subsequent dissolution and release of the isotope. This occurred most frequently in elderly subjects and was reduced by increasing the volume of water chaser. The sites of lodgment correspond to the location of the observed strictures in the patient population. An in vitro study showed that, when the causative drugs were mixed with saliva, dissolution occurred within 60 minutes and was associated with significant changes in pH. These investigations show that drug-induced esophageal strictures are more common than previously appreciated, and can be confused with a reflux etiology. Diagnosis is suggested by a history of drug ingestion, location of the stricture, and a normal esophageal acid exposure on 24-hour pH monitoring. The severity of the esophageal injury is variable and requires dilatation to resection for therapy.

Abstract
The diagnostic and therapeutic approach to the maiagement of lesions caused by ingestion of caustic substances has made substantial progress in the past few years and has now been codified. The linch-pins of the present approach are emergency endoscopy for an immediate assessment of the lesions and total parenteral nutrition to reduce the morbidity in patients whose lesions may be expected to take a long time to heal or may require surgical repair. The diagnostic and therapeutic protocol advocated derives from a close examination of the literature and from personal experience.

Abstract
An esophageal stricture was diagnosed in a 9-month-old quarterhorse by esophagoscopy and positive pressure contrast esophagography. Medical management and two attempts at surgical intervention were unsuccessful. The initial surgical technique used was a linear esophagotomy, mucosal resection and anastomosis, and closure of the muscular tunic, which resulted in a more severe stricture. The second surgical procedure was interruption of the stricture cicatrix by a single linear esophagotomy and primary closure of only the esophageal muscular tunic. This technique resulted in an increased lumen diameter, but failed to adequately resolve the stricture. Successful resolution of the stricture with return to a normal diet was achieved by a two stage repair using formation of an esophagostomy to stabilize the esophagus, followed by fenestration of the mucosal-submucosal cicatrix. Six months postoperatively, the horse was asymptomatic on a normal diet.

Abstract
The upper-gastrointestinal examinations of 32 patients (mean age, 11 years) with histologically proven Barrett's esophagus were reviewed to evaluate the radiologic findings in children. All patients had symptoms of chronic gastroesophageal reflux and/or esophagitis, including atypical findings such as aspiration pneumonia, seizures, and failure to thrive. Fourteen patients had other diseases that might predispose them to abnormal esophageal motility and gastroesophageal reflux. Twenty-five patients had single-contrast and seven patients had double-contrast examinations. Four patients had normal single-contrast studies; 24 had gastroesophageal reflux; 12 had strictures; 10 had esophageal ulcers; and only four had hiatal hernias. The most notable difference between the results of endoscopy and the upper-gastrointestinal studies was the rate of detection of esophageal ulcers. Ten of the patients with single-contrast studies had ulcers seen at endoscopy but not shown radiologically. No specific radiologic signs of Barrett's esophagus were found, although most of our patients had abnormal upper gastrointestinal studies.

Abstract
Esophageal atresia with tracheosophageal fistula may be associated rarely with distal esophageal stenosis. Three patients are reported with this combination of esophageal anomalies. In addition the clinical and radiologic features of 24 patients previously reported in the literature are reviewed. Careful evaluation of the distal esophagus during postoperative contrast studies in patients with esophageal atresia should be obtained to exclude distal stenosis. The presence of unrecognized distal esophageal stenosis may lead to complications of postoperative anastomotic leaks, poor healing of the anastomosis, aspiration, and impaction of a solid food bolus proximal to the stenosis.

Abstract
Esophageal intramural pseudodiverticulosis is an unusual condition manifested by tiny flask-shaped outpouchings in the wall of the esophagus. The condition was diagnosed in 21 (0.15%) of 14,350 patients undergoing radiologic examinations of the esophagus at our hospitals. The pseudodiverticula were detected only by single-contrast technique in five of 18 patients (28%) who underwent both single- and double-contrast examinations. Thus, thin, low-density barium seems to enter these structures more readily than the high-density barium used for double-contrast esophagography. While most patients reported in the literature have diffuse or segmental pseudodiverticulosis associated with high esophageal strictures, the majority of our patients (11 [52%] of 21) had isolated involvement of the distal esophagus with 10 or fewer pseudodiverticula in the region of a peptic stricture. Other associated conditions included Candida esophagitis, herpes esophagitis, and squamous cell carcinoma of the esophagus. Our experience suggests that pseudodiverticulosis usually represents a sequela of reflux esophagitis, although the reason that so few patients with esophagitis develop this condition is unclear.

Abstract
Strictures of the esophagus following surgical resection present uncommonly. Reports are few describing the occurrence and management of this entity especially in the contemporary literature. In general a postoperative stricture is approached in the same manner as any other type of esophageal stricture, i.e., by clinical, radiographic and endoscopic evaluation. In particular, the stricture is carefully examined endoscopically, appropriate biopsies and/or cytology obtained and dilation carried out. Methods of dilating these strictures include those techniques most commonly used and especially the method which is most familiar and comfortable for the endoscopist. Standard Eder-Puestow bougies, Maloney and Hurst dilators and Savary-Gilliard bougies exert forces along a longitudinal axis which may be more uncomfortable for the patient and associated with higher morbidity than balloon dilators, which exert forces along a radial axis. Dilatation of post-surgical esophageal strictures is performed as safely as possible with minimal discomfort to the patient and should provide long-term results requiring infrequent interventions.

Abstract
Early or late postoperative complications in 52 patients undergoing colic esophagoplasty for benign (27 cases) or malignant (25 cases) lesions of esophagus are discussed in relation to radiologic findings. Immediate postoperative complications due to infection were mainly bronchopneumopathies (14 cases), their incidence being increased by recurrent nerve palsy, and mediastinitis (3 cases). The frequency of upper anastomotic fistulae (16 cases) emphasizes the need for routine radiologic follow up on the 7th postoperative day by upper digestive tract follow-through examination with water-soluble contrast. Stenosis of upper part of graft may be of ischemic or fibrous origin. Ischemic stenosis develops 2 weeks to 4 months after surgery as a long filiform narrowing. Fibrous stenosis occurs in upper anastomosis at a later stage, after the 3rd month, as a short regular narrowing. Other complications are rare.

Abstract
Radiographic and endoscopic sensitivities were compared in 60 patients with lower esophageal mucosal ring. Barium esophagram detected 57 (95%) rings, all shown by the prone full-column technique. Double-contrast technique in 39 patients demonstrated only 18 (46%) rings. Endoscopy detected 35 (58%) of 60 rings. Endoscopic sensitivity depended on ring caliber with detection of 18 (82%) of 22 rings 13 mm or less in caliber, 14 (54%) of 26 14-19 mm rings, and three (25%) of 12 rings 20 mm or wider. Dysphagia was present in 13 of 25 patients with rings undetected by endoscopy. The caliber of the fiberoptic instruments used also affected endoscopic detection, with 47% of the rings being diagnosed with narrower endoscopes and 76% being diagnosed with larger instruments. Thus, the radiographic examination was more accurate in detecting lower esophageal mucosal ring and should be used initially in patients with dysphagia and suspected lower esophageal narrowing.

Abstract
Among 1134 patients, cineradiologically examined because of dysphagia, 85 (7.5%) had webs in the pharyngo-oesophageal segment. Webs were more common in women (10%) compared to men (5%). Radiologic characteristics of the webs such as precise location, multiplicity, circumferential extension, thickness, accompanying streamline phenomenon and encroachment on the lumen, were compared to the presence of concomitant anaemia, thyroid disease, neoplasm, as well as the age and sex of the patients. Webs were regularly deeper in women compared to men. Patients with iron deficiency anaemia had thicker webs compared to patients without such anaemia. No other radiologic characteristics were found that could be used for distinguishing these potentially more significant webs from those in patients without such concomitant diseases.

Abstract
Forty-four patients with dysphagia were examined both by endoscopy and by barium swallow with a marshmallow bolus. In these patients 36 stenoses were found: 34 by radiology and 30 by endoscopy. The radiologic criteria for stenosis included arrest of the marshmallow in a manner to support a column of barium and reproduction of the patient's symptoms at the time this occurred. Radiologic false negative findings were partly due to an inability by patients to swallow an adequate marshmallow bolus; endoscopic failures were associated with small endoscopes and mild stenoses.

Abstract
Severe esophageal stricture developed in four of 12 patients who survived for more than 2 years after treatment for esophageal cancer consisting of external irradiation followed by high-dose-rate intracavitary irradiation. The strictures were seen between 13 and 21 months after initiation of radiation therapy. The length of the strictures appeared to relate to the length of the tumor before treatment and to the magnitude of the intracavitary dose. One of the four patients was helped by balloon dilatation.

Abstract
In healthy persons the mean time of the passage of water through the esophagus was 3.75 +/- 0.12 s, that of 10% test meal 6.15 +/- 0.34 s. The average rates of the passage of water and test meals were 5.35 +/- 0.25 cm/s and 3.25 +/- 0.62 cm/s, respectively. In postburn cicatricial esophageal stenosis the time of the passage of water ranged within 5-9 s depending on a degree of stenosis, that of the test meal within 12-20 s, and the rates of their passage were 2-4 cm/s and 1-1.7 cm/s, respectively. While in some cases complete esophageal obstruction was shown by x-ray, scintigraphy revealed the presence of a lumen of the esophagus.

Abstract
Dilatation of benign esophageal strictures by means of a balloon-catheter is a well-established procedure in adults. This method is also useful in children. The technique is described and the results of treatment in 10 children are reported. In all our patients the stricture developed after an operation for esophageal atresia with an end-to-end anastomosis. Dilatation with a balloon-catheter seems to have the same or an even better effect than the traditional dilatation with bougies. Complications following balloon-dilatations have been few and negligible in this series and dilatations can be performed using sedation instead of general anaesthesia. Therefore, this method is recommended.

Abstract
Radiographic and endoscopic findings were correlated in 46 normal patients and in 49 with reflux esophagitis to assess the efficacy of a multiphasic examination employing mucosal relief full-column, and double-contrast techniques. Esophagitis was graded endoscopically as mild, moderate, or severe, and the quality and sensitivity of each technique and of the examination as a whole were determined. The radiographic specificity in the normal patients was 98%. The overall sensitivity was 65% for all grades of esophagitis, and 90% for the moderate and severe grades. Sensitivities of the individual techniques were: mucosal relief: 43%; full-column: 53%; double-contrast: 45%. These differences were not statistically significant. We conclude that a combination of radiographic techniques is needed to detect reflux esophagitis optimally.

Abstract
A prospective investigation on gastro-oesophageal reflux in 97 consecutive patients has been carried out by means of a barium examination employing the conventional method and after food stimulation. Gastro-oesophageal reflux was observed in 38 patients with and 15 patients without oesophageal symptoms. Gastro-oesophageal reflux was induced by two mechanisms, an active component after food stimulation and a passive component after the conventional method including respiratory manoeuvres and leg raising. In 32 patients, only the active component could be demonstrated and in 6 patients only the passive component. In the remaining 15 patients both active and passive components occurred. The clinical significance of the active and passive components in gastro-oesophageal reflux needs further investigation.
