A review of tongue lesions in children showed that there is a great variety requiring operative intervention, often in infancy. While the presenting symptoms may be related to dysphagia and dyspnea, the aim of operative intervention should not only be to salvage life by restoration of breathing and swallowing, but also to leave a tongue capable of adequate speech, taste, sensation, and normal orofacial development. Intimate knowledge of lingual anatomy and function is necessary to allow selection of the ideal procedure and appropriate timing of the therapy. While careful observation and nonoperative approach may be indicated in non-neoplastic macroglossia, early intervention is often necessary in diffuse neoplastic lesions such as lymphangioma, fibromatosis, or fibrolipomatous dysplasia. While malignant tumors are rare in childhood, they do occur and have to ruled out.

The natural history of Barrett's esophagus, particularly the prevalence and incidence of malignant changes in it, remains controversial. Furthermore the prognosis of surgically treated patients with carcinoma in Barrett's esophagus has not been elucidated fully. To examine these and other issues, the records of 65 patients with carcinoma in Barrett's esophagus presenting at the Lahey Clinic Medical Center from January 1973 to January 1989 were reviewed. During this period, 241 patients with documented Barrett's esophagus were seen, for a prevalence of carcinoma of 27%. Adenocarcinoma in Barrett's esophagus accounted for 30% of the surgically treated carcinomas of the thoracic esophagus during this period. All but four of these patients were men. Symptoms of chronic reflux were present in less than one half of the patients and dysphagia was often the presenting symptom. In eight patients the carcinoma was discovered on routine surveillance endoscopy, and in four patients progression of disease from benign columnar epithelium to dysplasia to carcinoma was documented. Tumors developed in six patients who had undergone previous antireflux surgery, and in four other patients a second carcinoma developed in residual Barrett's epithelium after a previous resection. Of the 65 patients, 61 (94%) were considered to have operable disease, all of whom underwent resection. Two patients (3.3%) died within 30 days of operation. The resected specimens were staged as follows: stage 0, 4; stage I, 10; stage II, 17; stage III, 25; stage IV, 4. Of the resected specimens, 73% showed areas of dysplasia adjacent to the tumor. The overall adjusted actuarial 5-year survival rate was 23.7%. The 3-year survival rate was 100% for patients with stage 0 carcinoma, 85.7% for patients with stage I carcinoma, 53.6% for patients with stage IIA carcinoma, 45% for patients with stage IIB carcinoma, 25.2% for patients with stage III carcinoma, and 0% for patients with stage IV carcinoma. The premalignant nature of Barrett's esophagus requires endoscopic surveillance to detect early carcinoma because symptoms often occur late or are absent. Antireflux surgery does not protect against the development of carcinoma. All of the Barrett's epithelium must be resected because a second carcinoma may develop in residual columnar epithelium. Severe dysplasia should be considered an indication for resection. Although operability and resectability rates are high, long-term survival is not. Early detection is mandatory if long-term survival is to be achieved.

Barrett's esophagus, a condition in which the distal esophagus is lined by columnar epithelium, is almost always caused by gastroesophageal reflux and often occurs in conjunction with a sliding hiatal hernia. Patients are typically white men in their 50s who smoke and drink, and they present with complaints of regurgitation, heartburn, and/or dysphagia. Endoscopic biopsies are required to confirm the diagnosis. Complications, such as stricture, ulcer, dysplasia, and malignant degeneration, occur in many cases. Adenocarcinoma is the most serious complication. Medical treatment, including life-style changes as well as pharmacologic therapy, usually relieves symptoms and heals esophagitis, but when it fails, antireflux surgery is indicated. Patients without evidence of dysplasia should undergo endoscopy yearly; those with mild dysplasia require more frequent surveillance. If biopsies disclose severe dysplasia, esophagogastrectomy should be performed.

In spite of the development of upper digestive tract fiberoptic endoscopy (FE) within the last 10 years, early detection of esophageal carcinoma (EC) is rare except in certain high-risk groups such as patients with head and neck cancers. The aim of this study was to assess the value of a meticulous histoendoscopic examination with vital toluidine blue (TB) staining in all alcohol and tobacco abusers undergoing FE for any reason except dysphagia. In 18 months, 100 patients (90 men, 10 women) who were over 40 years old and who consumed more than 80 g of alcohol and 20 g of tobacco per day underwent FE. No patient had a history of head and neck or esophageal cancer. FE was decided in 48 patients for epigastric pain, in 28 for esophageal varices, in 8 for weight loss, in 8 for anemia, in 7 for peptic disease, and in 1 for diarrhea. Staining with TB was carried out at the end of the examination and two routine biopsies were obtained 5 cm above the lower esophageal sphincter. Specimens were obtained from each abnormal area (TB + or TB -). Clinical ENT examination was recommended for all patients. Two esophageal carcinomas (1 microinvasive, 1 in situ) and 15 cases of dysplasia were detected. Dysplasia was classified as severe in 1 case, moderate in 9 cases, and mild in 5 cases.(ABSTRACT TRUNCATED AT 250 WORDS)

Between 1978 and 1988, 88 patients were referred for the surgical treatment of nonmalignant Barrett's esophagus. Nineteen patients required esophageal resection. Male/female ratio was 13:6; age range was 13 to 84 years (mean age, 49.8 years; median age, 40 years). Preoperative studies demonstrated strictures in 11 patients and ulcers in 7. Penetrating Barrett's ulcer resistant to treatment was the indication for resection in 5 patients. Ulcers penetrated to the pericardium (1 patient), pulmonary vein (1), lung (1), and mediastinum (2). Other indications for resection included undilatable strictures (2), previous operations (4), high-grade dysplasia (3), parietal cells lining the esophagus (1), patient's refusal of long-term surveillance (2), and the inability to exclude adenocarcinoma preoperatively (2). Reconstruction was achieved by colon interposition (15) or esophagogastrostomy (4), with one postoperative death. Mean follow-up was 41 months and was 100% complete. Of the 18 patients, 3 have occasional regurgitation but none have any dysphagia or weight loss. Esophageal resection is indicated in a select group of patients with Barrett's esophagus. Absolute indications include a deep penetrating ulcer confirmed intraoperatively, high-grade dysplasia, strong suspicion of cancer, and multiple previous operations. Relative indications include strictures not responding to dilation and young patients refusing long-term surveillance.

Of 89 patients diagnosed between 1973 and 1983 as having at least 3 cm of columnar-lined esophagus, 22 were found to have adenocarcinoma. There was no difference in sex ratio, smoking, or the use of alcohol between the benign and adenocarcinoma groups. The patients with adenocarcinoma were older (63 years versus 57 years) and had a higher frequency of dysphagia (64% versus 46%), gastrointestinal bleeding (36% versus 24%), extended columnar-lined esophagus (94% versus 28%), and epithelial dysplasia (68% versus 10%). Heartburn was less frequent in the adenocarcinoma group (59% versus 79%), but when it occurred, it was of longer duration (mean, 18.8 years versus 10.9 years). In 2 patients, progression from benign columnar-lined esophagus to early adenocarcinoma was observed. Of the patients with adenocarcinoma, 2 received palliative treatment without resection and died four and nine months later. Six underwent partial esophagogastrectomy with 1 postoperative death. Four had residual columnar-lined esophagus at the resection margins. In one of them, stricture developed and in one, anastomotic recurrence of adenocarcinoma; 1-year survival was 50%. Fourteen patients underwent total thoracic esophagectomy with no operative deaths, strictures, or anastomotic recurrences; 1-year survival was 5 of 6. Surgical staging revealed that 63% had transmural spread and 55%, lymph node involvement.(ABSTRACT TRUNCATED AT 250 WORDS)

A 59-year-old man was admitted to the hospital for dysphagia and fever. Esophagogram and upper gastrointestinal endoscopy revealed a polypoid mass in the midesophagus. Subtotal esophagectomy, cervical esophagogastrostomy, and lymph node dissection were performed. The histological diagnosis of the tumor was malignant fibrous histiocytoma. An area of severe epithelial dysplasia was found in the esophageal mucosa 3 cm under the tumor.

A total 17 cases of carcinoma oesophagus were studied in a period of 2 years. Ten patients (58.82%) were males and rest were females. Maximum cases (64.70%) were seen in 5th and 6th decades. Majority of the patients belonged to low socio-economic group (47.05%) followed by middle socio-economic group (41.17%). Dysphagia was present in all cases, followed by weight loss 52.94% and other symptoms. Cancer was equally distributed in middle third and lower third of the oesophagus (41.18% in each group) only in 3 cases it was in upper third of the oesophagus. Histologically 70.5% tumours were squamous cell carcinoma, 17.64% were adenocarcinoma and 11.76% were undifferentiated carcinoma. Surrounding epithelium in 17.64 per cent cases showed chronic oesophagitis, 4 cases (23.52%) showed acanthosis and dysplasia, and two cases revealed carcinoma in situ. Hence findings of oesophagitis, acanthosis, dysplasia, carcinoma in situ suggest that oesophagitis and acanthosis may be considered as precancerous lesions.

The authors report the case of a 60 year-old woman patient with esophageal papillomatosis, revealed by slowly progressive dysphagia and digestive hemorrhage. Multiple warty tumors were found at endoscopy, starting at approximately 23 cm from the dental ridge, increasing in size into the lower esophagus where they were responsible for stenosis. Pathological examination demonstrated epithelial proliferation with lengthened papillae, hyperkeratosis, hyperacanthosis and severe dysplasia. No extra-esophageal papillomata were discovered. Subtotal esophagectomy was performed and pathological examination with immune markers suggested a human papilloma virus (HPV) infection. However, search for HPV DNA was negative. To our knowledge, this constitutes the fifth case reported in the literature. The principal problem posed by this rare disease is the possible association with and/or progression to carcinoma, the diagnosis of which may be difficult, and particularly, with verrucous carcinoma. With this diagnostic uncertainty in mind, the authors suggest total surgical removal of the esophagus in this situation.

A 66-year-old woman, who had a stricture of the distal esophagus with Barrett's epithelium caused by gastroesophageal reflux, was operated upon by means of the fundic patch method. Preoperative manometric and pH studies revealed that the patient had a cardiac incompetence and a delayed acid clearance of the esophagus. Endoscopic biopsies between 33-35 cm from the incisors, above the gastroesophageal junction, showed columnar metaplasia with a villiform surface, mucous glands, intestinal goblet cells, moderate inflammatory changes and focal mild dysplasia. After the operation, relief of the dysphagia and reflux symptoms were obtained successfully, and an endoscopy done 7 months later demonstrated that the esophageal lumen was adequate enough for passage, and that there was improvement of the esophagitis, though persistent Barrett's esophagus without malignancy still existed. These results indicate that the fundic patch operation with the formation of a mucosal valve and 270 degrees fundoplication is a useful method of choice for benign strictures of the lower esophagus.
