Achalasia is a primary motor disease of the esophagus. It is rare in the pediatric population; fewer than 5% of patients are below 15 years of age. Progressive dysphagia is the most common presentation in adults. The clinical presentation in children does differ from adults. The various clinical features are nocturnal cough, recurrent pneumonia, vomiting, and feeding difficulties. The symptoms of achalasia may mimic gastroesophageal reflux disease in children. We report a 4-year-old boy presented with increasing difficulty in swallowing. Esophagram showed a smooth narrowing of the distal end and dilated esophagus. High-resolution manometry (HRM) had confirmed the diagnosis by fulfilling the criteria for achalasia Type 2. HRM has high sensitivity than conventional and may predict prognosis. He underwent Heller's myotomy with an anti-reflux procedure. The patient was asymptomatic after curative surgery. We report a rare case of achalasia in a 4-year-old boy confirmed by novel diagnostic technique HRM; hence, pediatric data of HRM are limited.

| Introduction|| |
Achalasia is characterized manometrically by impaired synchronized relaxation of the lower esophageal sphincter (LES) and aperistalsis in the body of the esophagus. It creates functional obstruction of the esophagus.
The etiology is unknown. Viral infection, autoimmune, or neurodegenerative process can destroy ganglion cells in the myenteric plexus. Consequently, lack of the release of neuroinhibitory substances, nitric oxide, and vasoactive intestinal polypeptide from inhibitory neurons has been diminished. Eventually, excitatory cholinergic becomes dominant and its uninhibited activity is the cause of manometric presentation of achalasia.,
The diagnosis is made by clinical history and radiography. Achalasia is confirmed by manometry.
Esophageal manometry is a procedure to determine how various factors come to play in the motility of the esophagus and function of the sphincter by measuring pressures developed by the esophageal muscles and the sphincter. A catheter is introduced from the nostril and is placed beyond the esophagogastric junction. The catheter carries a sensor that captures intraesophageal pressure signals and transmits those signals to receiving gadget. The reordered signals in receiving device represent the data.
New diagnostic manometry – high-resolution manometry (HRM) – is replacing conventional manometry. The distinguishing points between HRM and conventional presented in [Table 1]. Recent data coming out from HRM are showing greater sensitivity than the conventional one., Furthermore, HRM also predicts treatment outcome in adults. There is the dearth of HRM experience in children.

The treatment is aimed to the reduction of LES pressure and smooth esophageal emptying. Myotomy with partial fundoplication is most commonly recommended. The outcome is excellent with normal life expectancy.
We report the rare of achalasia and describe HRM in a child.
| Case Report|| |
A 4-year-old boy presented with increasing difficulty of swallowing for the past 3 months. At the time of admission, he had persisting vomiting, some dehydration, and pallor, with weight being 12 kg and height 96.5 cm (weight-for-height Z score <2 standard deviation). No abnormality was found on physical examination. Before admission, he has been receiving a proton-pump inhibitor trial in suspicion of gastroesophageal reflux disease (GERD), but that did not work. A routine blood test showed anemia. Serum creatinine, sugar, and electrolytes were normal. Upper gastrointestinal endoscopy showed large dilated esophagus and retained food material. The esophagram revealed smooth narrowing of the esophagus near to the cardia with a hugely dilated esophagus [Figure 1] and slow passage of contrast and no GERD demonstrated. HRM tracing [Figure 2] revealed aperistalsis and absent LES relaxation that is definitive diagnostic criteria for achalasia.

After initial conservative management nutrition by nasogastric tube, he was transferred to the pediatric surgery department. He was managed by Heller's cardiomyotomy and anterior fundoplication that was uncomplicated. The boy started to gain weight and nutritional recovery.
| Discussion|| |
Achalasia is a primary motility disease of the esophagus, presents with a slowly progressive manner.
The incidence of this rare disease is 2 per 105 per year and peak incidence age group is 30–60 years. It is rarely symptomatic in the pediatric population with an incidence of 0.11 per 105 children per year and <5% of patients are below 15 years of age. A high prevalence in male (male:female = 6:1) is reported, and the mean age of presentation in children approximately is 5 years. Our patient is male and admitted in the institute at the age of 4 years.
The clinical presentation in pediatrics is very different than adults and depends on age. The most common symptoms in children are regurgitation, weight loss, and recurrent respiratory tract infections which were found 79.1%, 79.1%, and 73.9%, respectively. Our patient had dysphagia that is also a common symptom and presented in 62.5% of children. The manifestations in infants are atypical: aspiration, difficulty in feeding, nocturnal cough, and pneumonia. Tracheal obstruction by achalasia is a very rare complication. Our patient was initially treated for GERD. Similar wrong diagnosis has been reported and 50% cases are initially misdiagnosed.,
Achalasia is suspected by clinical history and is supported by barium swallow studies. The assessment of esophageal motor function by esophageal manometry is strongly recommended to confirm the diagnosis. Although manometry considered as the gold standard for diagnosis, it is not available even in tertiary referral center.
The investigations such as barium esophagram and endoscopy are complementary for management. The esophagram revealed smooth narrowing of the esophagus near to cardia with a hugely dilated esophagus ([Figure 1]) and slow passage of contrast and no GERD demonstrated.
New diagnostic manometry HRM is replacing conventional manometry. Recent data coming out from HRM are showing greater sensitivity than the conventional one.,
Aperistalsis is an inability of contractile movement of the esophagus with various pressures in the esophagus. HRM analyzes the dynamic pressure signals through esophagus and depicts continuous topographical esophageal pressure which identifies motor patterns and prognosis after treatment in adults. Three motor patterns of achalasia are recognized in adults according to topographic presentations of body of the esophagus by this novel diagnostic procedure HRM. Those phenotypes are Type 1 – absence of pressurization, Type 2 – isobaric pressurization, and Type 3 – spastic, pressurization with contraction. Type III has worse prognosis than Type I and II.
There is the dearth of HRM experience in children. Our case revealed aperistalsis of the esophagus and high pressure at LES that depiction in our case corresponds to phenotype 2 of the adult. Furthermore, heterogeneous behavior of LES in children needs more experience with HRM for achalasia diagnosis.
HRM has the highest sensitivity to diagnose achalasia comparing others modalities, and replacing the conventional manometry. Furthermore, pediatric data of HRM are limited. We have confirmed the achalasia by HRM.
Surgery is the gold standard management of achalasia. Cardiomyotomy is the recommended choice for also in the pediatric age group. Two most common complications of surgery in published series are (i) recurrence of dysphagia (0%–26%) and (ii) perforation of the esophagus (0%–15%).
Overall prognosis is excellent in 90% achalasia. Our case is pursuing a normal life without any complications.
