Studies were carried out in a case of achalasia. Administration of secretin caused relaxation of the spastic condition of LES, and high levels of serum gastrin and lower levels of plasma secretin are suggested to be related with the abnormally spastic condition of LES in the patient.

Oesophagocardial plasty combined with intrathoracic fundoplication (Thal-Nissen-Rosetti) appears to be efficacious in the treatment of severe achalasia and of stenosis resulting from reflux in hiatus hernia. Advanced age and moderately severe cardiorespiratory disorders do not preclude good results from this operation. The above procedure was applied to six patients, with results varying from very good to fair.

Three brothers from the iron range of northern Minnesota developed typical symptoms of achalasia in adult life. The diagnosis of classic achalasia was confirmed in each brother by roentgenologic examination and by esophageal motility studies and each patient was treated successfully by forceful dilation of the lower sphincter or by esophagomyotomy. Although the three brothers were raised in the same home and all worked in the iron mines, it appears unlikely that environmental factors were responsible for the development of this disease. The etiology of achalasia in siblings remains obscure but a genetic origin (autosomal recessive) seems most likely.

1. The mechanical properties - extension behaviour and ability to contract per muscle cross-section - were the same for healthy and aganglionic cardiac sphincter. 2. The acetyl choline threshold is higher in aganglionic muscle strips. The maximum effective acetyl choline dose (2 microgram/ml) remained the same. 3. Achalasia is characterized by a considerable reduction of adrenergic beta-receptor activity and alpha-receptor predominance.

Intraulminal recordings of motility were made from a patient with chronic idiopathic intestinal pseudoodstruction. Contractile activity was recorded from esophagus and duodenum with and without cholinergic stimulation. Electrical activity was recorded from duodenum with and without cholinergic stimulation. Contractile and electrical activities were recorded from the sigmoid colon at rest and after morphine. Gastric fundic relaxation was measured during balloon distention. This patient showed abnormalities of esophageal function similar to achalasia, while gastric fundic relation was impared, with a more rapid rise in pressure on distention than is seen in normal persons. Duodenal and colonic electric control and response activities were present on occasion. Duodenal contractions occurred in response to both bethanechol and edrophonium. Therefore, the efferent cholinergic system of the small bowel appears to be functional in this case of idiopathic intestinal pseudoobstruction. The nonardrenergic inhibitory control of esophagus and gastric fundus appears to be functioning abnormally.

Through direct research on isolated human esophagus muscle systems in achalasia patients we found a deviation in the distribution pattern of the contractory alpha-receptors and dilatory beta-receptors in the region of the lower esophagus sphincter in favour of the alpha-receptors. Consequently, the motility of the lower esophagus sphincter was extremely impaired. On the basis of these results, we treated achalasia patients with the alpha receptor blocking drug phentolamine. All patients were soon symptom-free subjectively and improved objectively. Surgical intervention was avoidable in all cases.

As long as its etiology is uncertain, achalasia can only be treated symptomatically. Basically, conservative dilation treatment and operative cardiomyotomy can be performed. Although dilation treatment can save the patient the operative procedure, it has relative disadvantages. For this reason since 1973 we treat achalasia through cardiomyotomy with Nissen's fundoplication method. We have operated on 25 cases using this method. These are examined and the results reported.

Length tension diagrams and diagrams of isometrically developed active tension were set up for normal and aganglionic cardia-circular muscles. The effects of acetylcholin, adrenergic stimulating and inhibiting drugs were examined. The physiological parameters in healthy cardia and the cardia muscle system in achalasia did not vary significantly from one another. The acetylcholin threshold was higher in aganglionic cardia, while the maximum effective dose in healthy and aganglionic cardia remained the same. In achalasia no sensitisation to acetylcholine was detectable. There was a marked impairment in the balance between adrenergic alpha- and beta-receptors, with the contraction-inducing alpha-receptors obviously predominating.

A 31 year-old female initially presented with clinical features consistent with achalasia, which were relieved by the Heller procedure. Several years later manometric tracings excluded the diagnosis of achalasia, and suggested a motility disorder of the esophageal body. A long esophageal myotomy was performed and was followed by a marked improvement in symptoms and a normalization of the manometric tracing. Multiple histologic sections from the surgical specimen revealed the absence of ganglion cells, a feature not previously described in motor disorders other than achalasia. These findings suggest that classification of esophageal motility disorders on the basis of manometric and histologic findings might not be possible and that surgical treatment should be directed towards the predominant symptoms.

Six patients with myelomeningocele and the Arnold-Chiari malformation developed cricopharyngeal achalasia and lower cranial nerve deficits. Diagnosis is established by cine-esophagram. Distortion of the brain stem or cranial nerves secondary to the Arnold-Chiari malformation may produce the autonomic imbalance necessary for cricopharyngeal achalasia. Treatment is supportive and includes verification of cerebral spinal fluid shunt function. Suboccipital craniectomy may reverse progressive lower cranial nerve deficits and reduce cricopharyngeus spasm. Cricopharyngeal myotomy may be considered when the cranial nerve deficits and cricopharyngeal achalasia are fixed, irreversible, and continue to cause disability.
