Between 1980 and 1989, 15 of 46 patients (11 children, 4 adults) who underwent suboccipital craniectomy and cervical laminectomy for symptomatic Chiari malformations presented with manifestations of neurogenic dysphagia. Each of these patients had normal swallowing function before the development of dysphagic symptoms. Dysphagia was progressive in all 15 and, in most cases, preceded the onset of other severe brain stem signs. The rate of symptom progression varied depending on the age of the patient. Whereas the six infants (all Chiari II) deteriorated rapidly after the onset of initial symptoms, the five older children (two Chiari I, three Chiari II) and four adults (all Chiari I) showed a more gradual deterioration. In 11 patients with severe dysphagia, barium video esophagograms, pharyngoesophageal motility studies, continuous esophageal pH monitoring, and appropriate scintigraphic studies were useful in defining the scope of the swallowing impairment and determining whether perioperative nasogastric or gastrostomy feedings, gastric fundoplication, and/or tracheostomy were needed to maintain adequate nutrition and avoid aspiration. These patients all had widespread dysfunction of the swallowing mechanism, with a combination of diffuse pharyngoesophageal dysmotility, cricopharyngeal achalasia, nasal regurgitation, tracheal aspiration, and gastroesophageal reflux. The pathophysiology of these swallowing impairments and their relation to the hindbrain malformation is discussed. Postoperative outcome with regard to swallowing function correlated with the severity of preoperative symptoms. The four patients with mild dysphagia showed rapid improvement in swallowing function after surgery. Seven patients with more severe impairment but without other signs of severe brain stem compromise, such as central apnea or complete bilateral vocal cord paralysis, also improved, albeit more slowly. In contrast, the outcome in the four patients who developed other signs of severe brain stem dysfunction before surgery was poor. Early recognition of neurogenic dysphagia and expeditious intervention are therefore crucial in ensuring a favorable neurological outcome.

Among 11,821 cases of esophageal carcinoma treated in a 32 year period, 7 were found to be associated with achalasia (0.059%). Five cases were proved by biopsy or cytology and 2 were diagnosed by esophagograms. There were 4 men and 3 women. The age ranged from 30-54 years with a median of 38. The age was younger than that of esophageal carcinoma unassociated with achalasia. Duration of achalasia was from 7 to 20 years. Three patients died within 1 year and 1 died 17 months after diagnosis. Three were lost to follow-up. The presenting symptoms were aggravating dysphagia in 4; and hoarseness, dyspnea and bloody regurgitation in the other two. Patients with achalasia should be treated energetically in the early stage. Double contrast esophagography and esophagoscopy should be done carefully during the followup. Preparation of the esophagus is most important when performing the X-ray examination of the esophagus.

A 42 year old woman had undergone a Heller myotomy for achalasia of the cardia at age 28. Thereafter, she had become asymptomatic but reported for endoscopic follow-up examinations at three-yearly intervals. Fourteen years after surgery, endoscopy and biopsy revealed "carcinoma in situ" in the proximal esophagus and surgery was recommended. In the resected specimen, a circumscribed area of cancer was demonstrated that invaded the lamina propria but was confined to the mucosa. With the exception of mild and transient postoperative dysphagia, she had an uneventful postoperative course and remains well 16 months following surgery. This case demonstrates that endoscopic surveillance may detect early malignant changes in the achalasic esophagus and may possibly lead to an improvement in survival.

Modified Heller's myotomy for achalasia of the esophagus was performed via a left thoracotomy in 34 cases (group A) and via an upper midline abdominal incision in 30 (group B). There were no perioperative deaths. Complications arose in ten cases. After follow-up averaging 13 years (range 3-24 years) 4% of the group A patients reported dysphagia for solids, but none for liquids, and in group B the corresponding figures were 52% and 26%. Reflux symptoms were present in 30% of the group A and 60% of the group B cases, and the respective incidence of microscopic esophagitis was 30% and 43%. There were three esophageal strictures, all in group B, and three cases of Barrett's epithelium, all in group A. Because of the high incidence of esophagitis and its complications following esophagomyotomy for achalasia, yearly endoscopy with biopsy and brush cytology is recommended. When myotomy is performed, an antireflux operation should be added.

A 70-year-old woman with no previous gastroesophageal surgery gave a 6-month history of dysphagia. Barium studies suggested a diagnosis of achalasia. Esophageal manometry showed absence of peristalsis and a high lower esophageal sphincter pressure. Endoscopy showed a dilated esophagus with food residue, and Barrett's esophagus was present. The association of Barrett's esophagus and achalasia must be rare.

Conventional oesophageal manometry is seldom accompanied by symptoms and may indeed be normal in patients with a history of dysphagia. We have recently shown that oesophageal manometry during eating may be helpful in the evaluation of patients with dysphagia but there has been little systematic comparison of fed oesophageal motor patterns with conventional clinical manometry. Oesophageal manometry in response to water swallows and during eating was therefore examined in 58 consecutive patients who had been referred for clinical oesophageal function studies. The patients were divided into three groups according to the percentage of peristaltic activity during conventional manometry: group 1 (n = 21) had 100% peristalsis; group 2 (n = 29) had 1-99% peristalsis and group 3 (n = 8) were aperistaltic. All the patients in group 3 had achalasia and remained aperistaltic during eating, however, was less than with water swallows in both group 1 (53% compared with 100%) and group 2 (49% compared with 82.3%) patients. Synchronous contractions and non-conducted swallows were correspondingly increased during eating. Although there was a significant correlation between the amplitude of peristaltic contractions with water and bread in groups 1 and 2, mean peristaltic amplitudes were less with bread than with water swallows. The data show that there are substantial differences in the distal oesophageal motility patterns produced by water swallows and by eating. Conventional manometry with water swallows does not allow prediction of the fed oesophageal motility pattern, except in patients with achalasia.

Of 15 patients operated on for achalasia in the Department of General and Abdominal Surgery at the University of Mainz between September 1985 and April 1990, 14 were followed-up. All the patients had received an extramucous myotomy combined with Dor's semifundoplication; in twelve, one or more preoperative balloon dilatations had been performed. The results are reported in this study. The average age of the patients was 55.3 years (18 to 76 years), and the average follow-up period 21 months (six to 53 months). No postoperative complications were seen in any of the case. All patients reported appreciable improvements in their symptoms, six being completely symptom-free. Occasional dysphagia was reported in six cases, one patient had occasional, another frequent, nocturnal heartburn, which however had already presented preoperatively. In all seven cases submitted to postoperative radiological examination, the diameter of the esophagogastric junction was increased, and the diameter of the middle-third of the esophagus decreased. No gastroesophageal reflux or signs of inflammation were seen in any of the cases. The low complication rate and the high success rate despite prior balloon dilatation or bougienage support the use of Heller's operation combined with Dor's semifundoplication for the surgical treatment of achalasia after failed balloon dilatation.

Achalasia is the best known primary motility disorder of the esophagus. Dysphagia is the main symptom, intermittent at the beginning, but becoming more marked with evolution. Although some peculiarities are noted, they are not sufficiently characteristic to establish the diagnosis. Chest pain is often associated with dysphagia and may be the prominent complaint in the early stage of the disease. Dynamic investigations, mainly esophageal manometry, are needed for the diagnosis and follow-up after treatment. Three findings are commonly recorded: increase in lower esophageal sphincter pressure, lack of relaxation and absence of peristalsis, the latter being indispensable for the diagnosis of achalasia. On the basis of manometric findings, achalasia is easily differentiated from other primary motility disorders, i.e. diffuse esophageal spasm, nutcracker esophagus, but non-specific esophageal motility disorders are frequent. Manometry is also an objective method of assessing the effectiveness of treatment--i.e. surgical myotomy or balloon dilatation--of the lower esophageal sphincter.

1. A randomized, double-blind, placebo-controlled trial was carried out to determine the efficacy of isosorbide dinitrate (ISD) on dysphagia in patients with Chagasic achalasia. 2. Twenty-three patients with Chagas' disease and dysphagia entered the study and 20 (87%) completed the two 7-day treatment periods. Subjects were given either 5 mg ISD (12 patients) or placebo (11 patients) by the sublingual route for the first 7 days. On the 8th day, patients crossed over and began another 7-day period during which they received the opposite, identical-appearing tablets. 3. Scores attributed by uninformed investigators for the frequency and severity of dysphagia were significantly lower (P less than 0.05) following ISD treatment than after the placebo period or for the pretreatment condition. A significantly higher degree of improvement of dysphagia was experienced by the patients during ISD treatment than during the placebo period. Fourteen patients experienced meal-related headaches during ISD, but not placebo treatment. The extent of improvement in general well-being due to ISD was the same when the drug was given in the first or second test period. 4. Our results indicate that ISD, 5 mg by the sublingual route, is effective in alleviating dysphagia in patients with Chagasic achalasia but its usefulness is limited by the high rate of headache as a side effect.

A technique of laparoscopic cardiomyotomy is described. The procedure has been performed in a patient with manometrically confirmed classical achalasia with complete relief of episodic total dysphagia and no untoward symptoms including reflux. The procedure was followed by minimal postoperative discomfort and the patient was discharged on the third postoperative day. Laparoscopic cardiomyotomy has the advantage of diminished surgical trauma with accelerated recovery, constitutes definitive therapy comparable to standard myotomy, and by being less disruptive of the lower oesophageal fixation it is prone to precipitate gastro-oesophageal reflux.
