At that time they offered him a surgery, in a public hospital, but he declined it.  The incidence of achalasia is approximately 1 per 100,000 people per year. Chagas disease may cause a similar disorder due to Trypanosoma Cruzi.

Esophageal Achalasia.

 This 32 year old man has been suffering from esophageal
 achalasia  for about 10 years, which he has managed
 by
 meticulously cutting and chewing all his food. At that
 time they offered him a surgery, in a public hospital, but he
 declined it.

 At endoscopy, copious amounts of food and liquid were
 seen in the obviously dilated esophagus.

 The incidence of achalasia is approximately 1 per 100,000
 people per year. Chagas disease may cause a similar
 disorder due to Trypanosoma Cruzi.            Medline.   

The exact cause of achalasia is unknown.

                                                     Medline.

 The diagnosis of achalasia should be suspected in anyone
 complaining of dysphagia for solids and liquids with
 regurgitation of food and saliva. The clinical suspicion
 should be confirmed by a barium esophagram showing
 smooth tapering of the lower esophagus leading to the closed
 lower esophageal sphincter (LES), resembling a "bird's
 beak." Esophageal manometry establishes the diagnosis
 showing esophageal aperistalsis and insufficient LES
 relaxation. All patients should undergo upper endoscopy to
 exclude pseudoachalasia arising from a tumor at the
 gastroesophageal junction.

 Achalasia. Detail of a barium swallow study demonstrating the classic bird's beak deformity of the distal esophagus showing a dilated esophagus.  Achalasia is an esophageal motor disorder characterized by incomplete relaxation of the lower esophageal sphincter and by the absence of esophageal peristalsis. Progressive dysphagia and regurgitation can compromise oral intake and lead to malnutrition and weight loss. Treatment of moderate to severe cases of achalasia involves either balloon dilation or myotomy.

Pneumatic balloon dilation in achalasia. Our patient underwent a dilatation with special ballon used for achalasia.                                                                     Mechanical therapy for achalasia consists of esophageal dilation, the object of which is to disrupt muscle fibers of the LES, effecting a decrease in LES pressure. Dilation is most commonly performed by using pneumatic balloons. The therapy is successful in decreasing LES pressure in 60-80% of patients; however, this change does not always translate into the relief or improvement of symptoms. Approximately one half of patients experience recurrent symptoms within 5 years. In most of these patients, the disease responds well to repeated dilation therapy.

Pneumatic dilatation under endoscopic guidance.    Pneumatic balloon dilation is considered by many to be the treatment of choice for achalasia of the esophagus.  Dilation procedures are done as an outpatient procedure using only mild sedation with fentanyl and midazolam. Sedation is kept to true conscious sedation to assist the operator in evaluating severity of dilation induced chest pain.

This 78 year-old female 20 years previously underwent a surgery due to Esophageal Achalasia, (Esophagomyotomy of the lower esophageal sphincter (LES) ). Heller esophagomyotomy, since one month she has vomiting and weight loss. The upper endoscopy shows a typical picture of esophageal achalasia which was dilated with the same balloon that has been showed in this chapter. Esophageal dysfunction progresses through accumulation of ingested material in the superior portion of the esophagus, facilitating the aspiration of this material. This condition is more common in individuals in whom the cough reflex has been lost or suppressed due to neuromuscular disturbances, or due to the use of sedatives or other drugs. In such cases, aspiration pneumonia becomes established.

The esophagus is found to be dilated with rest of food. Achalasia is a rare disease of the muscle of the esophagus which is usually diagnosed in young adults. The term achalasia means "failure to relax" and refers to one of the abnormalities of the esophagus seen in the disease, specifically. The inability of the muscle at the lower end of the esophagus (the lower esophageal sphincter) to open and let food pass into the stomach.  In addition, the muscle of the lower half of the esophagus does not contract normally to propel food down the esophagus and into the stomach. Both of these abnormalities result in food sticking in the esophagus after it is swallowed.

Achalasia is an esophageal motor disorder characterized by increased lower esophageal sphincter (LES) pressure, diminished-to-absent peristalsis in the distal portion of the esophagus composed of smooth muscle, and lack of a coordinated LES relaxation in response to swallowing. Primary achalasia is the most common subtype and is associated with loss of ganglion cells in the esophageal myenteric plexus These important inhibitory neurons induce LES relaxation and coordinate proximal-to-distal peristaltic contraction of the esophagus.  Secondary achalasia is relatively uncommon. This condition exists when a process other than intrinsic disease of the esophageal myenteric plexus is the etiology. Examples of maladies causing secondary achalasia include certain malignancies, diabetes mellitus, and Chagas disease.

Neuromuscular disorder of the esophagus characterized  by a lack of reflex relaxation of the distal esophageal sphincter, normally induced by swallowing. Achalasia produces a functional obstruction of the esophagus with proximal dilatation. However, the disease involves the entire organ in which the normal neuromuscular disorder  peristaltic waves are replaced by simultaneous contractions. Achalasia occurs mainly in adults and rarely in children.

More forceful maneuver to perform dilation  Forceful balloon dilation was the mainstay of treatment for achalasia for many years. In this procedure, a pneumatic balloon is passed down the esophagus, half above and half below the LES. The balloon is then rapidly inflated for about a minute. As the balloon expands, it forcefully stretches and weakens the LES. Forceful pneumatic dilatation can be very successful and may last for a decade or longer.

Achalasia. It took forceful maneuvering of the endoscope to overcome the sphincter. Pathophysiologic studies of achalasia have primarily identified neural lesion involving loss of ganglion cell within the myenteric plexus, degeneration of the vagus nerve, and changes in the dorsal motor nucleus of the vagus. These changes result in aperistalsis in the esophageal body, impairment of lower esophageal sphincter relaxation.

The most widely accepted current theories implicate autoimmune disorders, infectious diseases, or both. The last decade has witnessed much progress in the understanding of the cellular and molecular derangements in achalasia. Degeneration of the esophageal myenteric plexus of Auerbach is the primary histologic finding. However, with early achalasia, a mixed inflammatory infiltrate of T cells, mast cells, and eosinophils is found in association with myenteric neural fibrosis and with a selective loss of inhibitory postganglionic neurons from the Auerbach plexus. In these patients with early achalasia, neurons of the myenteric plexus are relatively well preserved.
