Presentation
Abstract Pseudoachalasia or secondary achalasia is commonly recognized and sought for in the context of an elderly patient presenting with weight loss and brief duration of symptoms. [ncbi.nlm.nih.gov]

Decrease in Height
Good response was defined as a decrease in ASS of at least 50% of baseline and decrease in height and volume of barium of at least 50% of baseline in TBE, at 1.5 months after the last injection. Side-effects were recorded. [ncbi.nlm.nih.gov]

Endoscopy The primary role of EGD in the workup of achalasia is focused on ruling out a mechanical obstruction or pseudoachalasia as they can mimic achalasia both clinically and manometrically (( 10, 32, 33 )). [gi.org]
infections) as well as family history, particularly of autoimmune diseases, can contribute to directing the workup of the patient with suspected achalasia. [clinicaladvisor.com]

-
HLA-DQ1
By use of serological methods, a significant association between the HLA-DQ1 phenotype and idiopathic achalasia has been found, suggesting a possible immunogenetic mechanism. [ncbi.nlm.nih.gov]

Treatment
CONCLUSION: Adequate comparative data are lacking to determine the ideal treatment of pediatric achalasia. [ncbi.nlm.nih.gov]
Prognosis
Prognosis The prognosis in IA patients is excellent. Most patients with IA who are appropriately treated have a normal life expectancy but the disease does recur and the patient may need intermittent treatment. [orpha.net]
The prognosis in achalasia patients is excellent. Most patients who are appropriately treated have a normal life expectancy but the disease does recur and the patient may need intermittent treatment. [regione.lazio.it]
The prognosis of this disease is good. Uroflowmetry, cystometry and micturating cysto-urethrography are mandatory for the correct diagnosis. 1977 S. Karger AG, Basel Article / Publication Details First-Page Preview [karger.com]
Prognosis: 30% success after 1 dilatation, 60% after 2-3 dilatations, the remaining patients should be offered laparoscopic myotomy. Complication: perforation in 4% of the cases. [refluxmedical.com]
Treatment and prognosis Treatment is aimed at allowing adequate drainage of the esophagus into the stomach. [radiopaedia.org]
Etiology
Abstract The most important etiologies of achalasia are idiopathic and related to Chagas' disease. [ncbi.nlm.nih.gov]
Etiology Although the precise etiology is unknown, it is often thought to be either autoimmune, viral immune, or neurodegenerative. [orpha.net]
Epidemiology
In the present study, we carried out an epidemiological survey and a genotype-phenotype (G P) analysis to gain further insights into the etiology of achalasia. [ncbi.nlm.nih.gov]

Pathophysiology
The pathophysiologic abnormalities may be the final result of several intermeshing mechanisms, and more than one single factor may cause the motor abnormalities. [ncbi.nlm.nih.gov]

Anti reflux surgery (Dor fundoplication) is performed to prevent reflux. Prevention One cannot prevent the development of Achalasia. Self test Swallowing difficulties may indicate the development of Achalasia. [refluxmedical.com]
Laparoscopic myotomy with partial fundoplication is superior to other treatment methods because of its excellent efficacy and safety, and also prevent acid exposure in the distal esophagus. [ibimapublishing.com]
How can achalasia be prevented? This disease cannot be prevented. There are no known prophylactic drugs or vaccines available. There are no known behavior factors that can prevent the disease, but behavioral changes can help with outcomes. [clinicaladvisor.com]
This could prevent sigmoid-type achalasia[ 37 - 39 ]. [wjgnet.com]
