Radiologic diagnosis of Barrett's esophagus: critical analysis of 65 cases.

A recent increase in the number of Barrett's esophagus being diagnosed is probably directly related to a proportional increase in endoscopic biopsies of the esophagus and awareness of premalignant potential of Barrett's mucosa. While the endoscopist can detect Barrett's mucosa with fair degree of accuracy, the radiologic diagnosis of Barrett's esophagus still remains a diagnostic challenge despite several well established radiologic features. We reviewed 65 patients with pathologically proven Barrett's esophagus and found a wide spectrum of radiologic features. These include hiatus hernia in 49, gastroesophageal reflux in 38, strictures in 32, esophagitis in 20, and characteristic Barrett's ulcer in 12. In addition ascending or migrating strictures were found in 10, mucosal pattern simulating areae gastricae in 5, cricopharyngeal dysfunction in 4, and fixed spiral folds in 3 patients. This constellation of radiologic features, some of which have not been previously emphasized, should further assist radiologists in suggesting the diagnosis of Barrett's esophagus.

Gastric secretion of acid and pepsin in patients with esophageal stricture and appropriate controls.

Most cases of esophageal stricture are associated with acid/peptic reflux esophagitis. While patients with strictures commonly have disordered lower esophageal sphincters and poor clearance and neutralization mechanisms, it is not known whether they also have abnormal gastric secretion. This study examined fasting, basal, and stimulated acid and pepsin secretion. With an endoscopic diagnosis of esophagitis, patients with stricture (< 12.5 mm) were matched for age, sex, concurrent gastrointestinal disease (duodenal ulcer, N = 9), Zollinger-Ellison syndrome (N = 6), and postgastric surgery state (N = 5), as well as the absence of ulcer disease (non-DU, N = 37). Fasting, basal, and pentagastrin-stimulated acid and pepsin secretion were measured. Overall, the 57 stricture patients had the same acid and pepsin secretion as their matched controls with esophagitis; the same was true for each of the subgroups (ZES, DU, non-DU, and postsurgical). Stricture patients weighed less and had a lower body mass index (P < 0.01). Patients with esophageal peptic stricture have the same acid and pepsin output as control patients matched for sex, age, background gastrointestinal disease, and the presence of esophagitis.

What is the place of antrectomy with Roux-en-Y in the treatment of reflux disease? Experience with 83 total duodenal diversions.

Antrectomy with Roux-en-Y gastrojejunostomy was performed in 83 patients with "complicated" forms of peptic esophagitis. The esophagitis was considered complicated either because of the severity of the lesions (stricture, brachyesophagus, or endobrachyesophagus) or because of postoperative conditions after one or more previous operations (Heller's myotomy, esophagogastric resections, or hiatal hernia repair). A standard procedure was performed in 56 patients while technical adjustments were required for 27 patients who had previously undergone surgery. Two patients died from pulmonary embolism. Early postoperative complications occurred in 11% of patients. Healing of esophagitis was observed for all the patients treated with the standard procedures. Six partial regressions and 1 complete regression of Barrett's mucosa were observed. Digestive sequellae were minor and decreased with time. Assessment of pH and small bowel manometry showed that the reflux was controlled and no small bowel motility disturbance was observed when the standard technique was used including a small gastric resection. The main digestive sequellae, including lack of healing of esophagitis, dumping syndrome, and gastrojejunal anastomotic ulcer, occurred when a two-thirds gastrectomy was performed in order to avoid vagotomy.

Surgical management after failed antireflux operations.

From 1973 to 1989, 117 (28%) patients underwent re-operation for failed antireflux surgery from a total of 413 esophagogastric operations for gastro-esophageal reflux disease. Seventy-eight patients who underwent re-operation before 1984 were reviewed in detail for classification and long-term outcome. Forty re-operations followed a failed Nissen fundoplication, while no other procedure was the most recent prior operation in more than 10 patients. Re-operation rates were 3% following prior surgery in our clinic for reflux disease other than stricture and 9.6% if the prior operation was done for stricture. There was no difference in re-operation rates for the Belsey Mark IV or Nissen fundoplication, the 2 most commonly used repairs. In each case, complete pre-operative evaluations included symptom score, radiography, endoscopy, and esophageal function tests. Based on the results, the 78 patients were classified as pure sphincter mechanism failure to stop reflux (n = 14), pure esophageal clearance failure (n = 12), combined sphincter mechanism failure and clearance failure (n = 29), alkaline reflux (n = 9), or no reflux but another condition found (n = 14). Patients having symptoms following a prior Nissen fundoplication or Angelchik prosthesis insertion were more likely to have esophageal clearance failure than those having other repairs. The classification proved to be a useful guide to the need for and types of re-operation chosen. Among the 117 patients undergoing re-operation, there were 2 (1.7%) deaths within 3 months of surgery and 25 (21%) complications.(ABSTRACT TRUNCATED AT 250 WORDS)

Hospital discharges resulting from esophagitis among Medicare beneficiaries.

Despite the frequent occurrence of gastroesophageal reflux disease, until now only very few studies have dealt with the epidemiology of this common disorder. The Health Care Financing Administration complies annually 10 million records of all hospital discharges among Medicare beneficiaries distributed throughout the United States. The purpose of the present study was to take advantage of this large data set and analyze the demographic characteristics of patients discharged with esophagitis, esophageal ulcer, or esophageal stricture. The hospital discharge rates of all three diagnoses showed an age-related rise, the rise being most pronounced for esophageal stricture and, less significant, esophageal ulcer. The marked age dependency of esophageal stricture and ulcer may reflect the time necessary for complications to develop. While simple esophagitis affected women more frequently than men, significantly more men contracted its severe forms involving ulcers and strictures. All forms were more common in whites than blacks, and living in the southern parts of the United States was associated with an increased risk for esophagitis and strictures. The data suggest that besides varying exposure to environmental risk factors, differences in the pathophysiology among demographically stratified groups contribute to the occurrence of esophagitis.

Role of omeprazole in prevention and treatment of postendoscopic variceal sclerotherapy esophageal complications. Double-blind randomized study.

Endoscopic variceal sclerotherapy-related esophageal complications are quite common. The potential efficacy of omeprazole in the prevention and treatment of postsclerotherapy esophageal complications was evaluated in 47 patients with portal hypertension in randomized, placebo-controlled study. Twenty-one patients in the omeprazole group and 23 patients in the placebo group completed the study. The two treatment groups were similar in regards to the etiology of portal hypertension, Child's class, and clinical characteristics. Esophageal ulcers developed in 16 patients in the omeprazole group (2.43 ulcers/patient) and 18 patients in the placebo group (2.39 ulcers/patient). Most of the ulcers (> 90%) healed within 14 days in each group. Esophageal strictures requiring dilatation developed in two and one patient in the omeprazole and placebo groups, respectively. There was no statistically significant difference in regards to the complication rate between the two groups. We conclude that omeprazole is not effective for the prevention or treatment of postsclerotherapy esophageal complications.

The treatment of post-operative and peptic esophageal strictures after esophageal atresia repair. A program including dilatation with balloon catheters.

Nine patients, 6 weeks to 17 years of age with esophageal atresia (EA), developed esophageal strictures and were treated with 26 balloon catheter dilatations over a period of 3 years; 6 are now asymptomatic. Five of the 9 patients had suspected reflux esophagitis, confirmed in 3 by biopsy and treated medically prior to dilatation. Seven of the 9 patients had a primary anastomosis, 1 a gastric tube, and 1 a colonic interposition. Most dilatations in the group of 7 were performed with balloon (B) greater than or equal to the diameter of the distal esophagus (E) (B/E greater than or equal to 1). The 3 residually symptomatic patients include an infant dilated conservatively (B/E less than 1) to facilitate later bouginage, 1 patient with a recurrent stricture after stopping medical therapy and home bouginage, and 1 infant who had a persistent anastomotic stricture, suspected but untreated reflux esophagitis, and a perforation during the second balloon dilatation. Balloon catheter esophageal dilatation, as an alternative to bouginage, is usually a safe and effective procedure when reflux esophagitis is diagnosed and treated prior to dilatation.

Evaluation of esophageal transit in children and in infants by means of Krypton-81m.

This paper presents the results of Krypton-81m esophageal transit study in a series of children and infants presenting various esophageal disorders. The advantage of Kr-81m, compared to other radionuclides, is that the radiation dose to the patient is extremely low. The study can therefore be repeated as often as necessary and a high dose can be given to ensure good quality results. The method is very easy to perform and allows a quantitative assessment of esophageal transit in physiological conditions. The method gives information about the severity of altered transit and it is particularly useful in studying the effects of treatment.

Results of fundic patch operation for severe stricture of the esophagus.

Eighteen patients ranging in age from 32-82 years with benign distal esophageal stricture underwent and survived fundic patch operation. Twelve of these patients had undergone esophageal dilatation but without success. Five had had surgery for hiatal hernia using Hill, Belsey or Lortat-Jacob techniques. Middle laparotomy was done in five and left thoracotomy in thirteen. A fundic patch with a 270 degrees fundoplication was performed in seven and a fundic patch with 360 degrees fundoplication in the remaining eleven. The average hospital stay was 12.3 days. Dysphagia disappeared in seventeen and persisted for eight months in one patient. Three patients required instrumental dilatation for a few months. Endoscopic examination, pH study and X-ray fluoroscopy were done. Gastroesophageal reflux was nil in patients treated with Nissen's 360 degrees fundoplication and three of these 7 patients without Nissen's fundoplication had gastroesophageal reflux. Epithelialization of the patched esophageal wound was evident 6 months after the operation.

Transabdominal extensive esophagogastric devascularization with gastroesophageal stapling for management of noncirrhotic portal hypertension: long-term results.

Outside Japan portosystemic shunts have been favored as the surgical procedure of choice for the management of portal hypertension of noncirrhotic etiology. Devascularization procedures have resulted in high rebleed rates probably owing to a limited extent of devascularization. We performed this study to assess the efficacy of our modification of Sugiura's procedure for long-term control of variceal bleeding in patients with noncirrhotic portal hypertension. Forty-six patients with extrahepatic portal venous obstruction (EHPVO) and 22 with noncirrhotic portal fibrosis (NCPF) were subjected to transabdominal extensive esophagogastric devascularization with esophageal or gastric stapled transection (modified Sugiura's procedure), 38 in an emergency situation and 30 electively. Follow-up endoscopies were performed every 6 months. Operative mortality, morbidity, variceal status, and causes of recurrent bleeding were evaluated. The postoperative mortality was 4%. Early procedure-related complications were seen in 6%, and esophageal strictures formed in 7 of 45 survivors undergoing esophageal transection (15%). Over a mean +/- SD follow-up of 53 +/- 34 months, 95% of patients were free of varices. Seven survivors (11%) had a rebleed, but only 5% were due to varices (two esophageal, one gastric). Six (9%) patients developed gastropathy. The 5-year survival was 88%. The modified Sugiura's procedure is safe and effective for long-term control of variceal bleeding especially in the emergency setting and in patients with anatomy unsuitable for shunt surgery or if surgical expertise for a shunt operation is not available.

Radiation-induced esophageal strictures in children with cancer.

The purpose of this study was to determine the long-term esophageal side effects of irradiation and (doxorubicin) chemotherapy given to children with cancer. Barium esophagograms and medical records of 18 patients with esophagitis who received between 1200 and 5580 cGy to the chest and chemotherapy were reviewed. The age range was 3-14 years. Esophageal strictures occurring 1-10 years after therapy were found in 5 patients with lymphoma; 3 of the five received doses of 4000 cGy or greater. Three children with esophagitis who received doses of 4000 cGy did not have stricture formation. However, their follow-up time was only 1-3 years. Of the 5 patients with esophageal stricture, 4 were treated with multiple dilatations, and a fifth required colonic interposition. Combined mediastinal irradiation and chemotherapy can result in esophageal stricture 1-10 years after therapy.
