In the light of three cases of esophageal carcinoma developing on a pre-existing idiopathic megaesophagus the authors examine etiopatological, clinical and terapeutic problems related to this association. They believe that carcinoma of the esophagus tends to be a complication of cardiospasm in patients inadequately treated for the primary condition. Early diagnosis and an adequate Heller operation for cardiospasm will lessen the chance of cancer developing in megaesophagus with stasis. When finally diagnosed, this variety of esophageal carcinoma has an extremely poor prognosis. An even more important claim upon the clinician is to be alert to the hazards of continued stasis in megaesophagus and to devise earlier techniques of recognition, including more frequent recourse to biopsy during esophagoscopy.

A prospective study of 595 patients treated by the Thoracic Surgical Unit (TSU) at the University College Hospital (UCH), Ibadan between July 1975 and December 1977 was carried out to determine the pattern of thoracic surgical diseases in Nigeria and to prove or disprove the rarity of certain cardiopulmonary diseases in tropical Africa. This review shows that pyogenic infections of the lung and pleura constitute the largest percentage (38.5) of the thoracic surgical diseases in Nigeria. Although pulmonary tuberculosis accounts for only 23.4 percent of our total inpatient load, it constitutes about 60 percent of our outpatient clinic practice. Cardiovascular diseases form 12.9 percent, notably congenital and acquired valvular heart diseases. An interesting finding was the occasional association of pyomyositis with pyogenic pericarditis and empyema thoracis. This triad is being investigated. Chest trauma was the most common thoracic surgical emergency accounting for 9.2 percent of the total thoracic surgical pathology. The most common causes of dysphagia are strictures from corrosive esophagitis, achalasia, and carcinoma of the esophagus. Present experience confirms the rarity of hiatus hernia, reflux esophagitis, atherosclerotic cardiovascular disease, and, perhaps, carcinoma of the lung among Nigerians.

Achalasia is believed to be a predisposing factor for the development of esophageal cancer. Small cell carcinoma of the esophagus is a rare neoplasm, with fewer than 150 cases having been reported in the world literature, and it has been described only once previously in a patient with longstanding achalasia. We describe a case of an 85-yr-old woman with long-term primary achalasia who developed primary small cell carcinoma of the esophagus. We hypothesize that this patient's recurrent, worsening dysphagia is related to a paraneoplastic phenomenon. We discuss this association and review the literature.

Thirty-three operations for subtotal esophagectomy with one-stage plastics with a gastric pedicle without thoracotomy were carried out between 1985 and 1988. The indications for the operation were as follows: carcinoma of the esophagus (17) and of cardioesophageal localization (7), cicatricial stricture of the esophagus (6), IV degree cardiospasm (2), unspecific esophageal ulcer (1). The esophagus was resected through a laparotomo-transdiaphragmatic-cervical access, the graft formed from the greater curvature of the stomach was passed in the posterior mediastinum with the establishment of a cervical esophagogastroanastomosis. Postoperative complications occurred in 29 patients: incompetence of the anastomosis (26), mediastinitis and pyothorax, (4), peritonitis (2), pneumonia (4). Six patients died. With the performance of intrapleural esophagogastroplasty the mortality rate fell from 25 to 18.2%. The authors claim that subtotal esophagectomy with posteromediastinal gastroplasty without thoracotomy is a less traumatic and safer operative intervention.

Over a 5-year period 82 patients underwent 244 fibreoptic endoscopic dilatations for oesophageal stricture. A total of 55 patients had benign peptic oesophageal stricture caused by reflux oesophagitis. Two-thirds of these patients had good symptomatic relief with dilatation combined with medical treatment of reflux, whereas one-third had an unsatisfactory result. The practice of endoscopic dilatation in benign stricture proved to be safe and was cost-effective as the procedure was carried out under intravenous sedation on a day-care basis. Three patients underwent dilatation for achalasia with good results in two cases. There were 16 patients with malignant oesophageal stricture and, in this group, fibreoptic endoscopic dilatation had little role to play in relieving dysphagia and its practice was associated with a substantial morbidity and mortality. Dilatation of malignant strictures facilitated biopsy and was used prior to oesophageal intubation. The virtues of the Atkinson or Celestin tube put in with the Nottingham introducer are summarised. Eight patients developed anastomotic stricture after resection of carcinoma of the oesophagus and dilatation provided only very transient relief of dysphagia in this group. Most anastomotic strictures represented recurrent malignancy and the difficulty in gaining biopsy proof endoscopically is emphasised. We advocate the early use of a CT scan in this situation to make the diagnosis of recurrent malignancy so that, if appropriate, palliative treatment can be instituted while the patient's general condition is good enough to benefit from it.

Forty-six patients with esophageal achalasia required reoperation between January 1970 and January 1986. Three of these patients required a second reoperative procedure, for a total of 49 reoperations. Indications for reoperation were inadequate myotomy, 17; gastroesophageal reflux, 14; concomitant antireflux operation, six; incorrect diagnosis, four; carcinoma of the esophagus, four; megaesophagus, three; and paraesophageal hernia, one. Various procedures were employed at the time of reoperation, including revision of the myotomy, takedown or revision of a previously performed wrap, fundoplication, and resection. Of the 48 patients available for follow-up study over an average postoperative period of 5 years, the condition of 38 (79%) was considered to have been improved by reoperation. The best results were obtained by revision or takedown of a previous wrap (an improvement rate of 88.9%) and radical resective procedures (89% to 100%). We conclude that for good results to be achieved after reoperative achalasia procedures, the preoperative diagnosis must be accurate, the operation should be performed early before the development of megaesophagus, and a short but complete esophagomyotomy must be performed, preferably without the addition of an antireflux procedure. Elimination or revision of a previously performed fundoplication can be expected to be followed by good results. The precise indications for radical resective procedures have yet to be defined clearly, but their wider application to carefully selected patients with postoperative achalasia seems justified.

During a 20 year period we observed that in six patients with carcinoma of the esophagus associated with achalasia, four patients had had a prior Heller operation. Fifty patients with achalasia of the esophagus took part in endoscopic and histologic surveillance 5-15 years after cardiomyotomy. We have found a correlation between the severity of histologic changes and the duration of symptoms before the operation. It seems reasonable to advise early therapy to avoid the development of a dilated, poorly emptying esophagus. Our results suggest that long-term regular surveillance of the patient with achalasia is essential even after surgical treatment.

This report describes our experience with six patients with dysphagia as the sole manifestation of radiographic, inconspicuous primary lung cancer and well-defined esophageal lesion by barium swallow. Esophagograms suggested leiomyoma, benign esophageal stricture, duplication cyst, achalasia, and primary carcinoma of the esophagus. Careful evaluation of the chest radiographs in all patients presenting with dysphagia is emphasized. The majority of esophageal findings are subcarinal and bronchoscopy should be considered essential in the workup of these patients.

Carcinoma of the esophagus is found more commonly in association with head and neck tumors, lye stricture, achalasia, and Barrett esophagus than in the general population. Our experience with these associated entities in a population of 680 patients with carcinoma of the esophagus is reviewed. Carcinoma of the esophagus has traditionally had a very poor prognosis which continues to the present. Routine periodic use of double contrast esophagography is advocated to screen populations containing these associated high-risk entities. This may ultimately increase survival through diagnosis of earlier stages of carcinoma of the esophagus.

Achalasia of the esophagus is presumed by many to be a premalignant lesion leading to an increased risk of squamous cell carcinoma. There is disagreement, however, as to the precise risk of malignant degeneration and there is no consensus as to either the need for close surveillance of achalasia patients or the surveillance technique that should be employed. A review of the available literature on the subject has disclosed a wide range of reported cancer risks in achalasia patients, from zero to 33 times that of the normal population. Cancers, when discovered, are often unresectable and the median survival when they are resectable is low. A personal experience with 241 achalasia patients treated during the past quarter of a century disclosed that 9 had carcinoma, for a prevalence of 3.7%. Carcinoma developed in 3 of these 9 while they were under our observation. This translates into one cancer per 1,138 patient-years of follow-up, an incidence of 88 per 100,000 population, and a risk 14.5 times that of the age-adjusted and sex-adjusted general population. Because of the low postresection survival rate if treatment is delayed until carcinoma of the esophagus becomes symptomatic, closer surveillance of achalasia patients is recommended than has been the case. Because it seems unlikely that close endoscopic surveillance will prove to be cost-effective, periodic (every 2 to 3 years) blind brush biopsy warrants further study as a means of surveillance.
