Difference Between Achalasia and Stricture

Achalasia and strictures can both occur in the oesophagus. Although these conditions involve the same beefcake, these are significantly unlike. Achalasia involves the inability of a ring-shaped muscle in the oesophagus to relax, whereas an oesophageal stricture refers to narrowing or tightening of the tube of muscle that makes up the oesophagus. The symptoms of the 2 conditions may be very shut in presentation, simply there are specialized tests which are key indicators of which status the patient is suffering from.

Departure betwixt achalasia and stricture

Definition of achalasia and stricture

Achalasia is a condition that occurs when the musculus of the oesophagus becomes affected. When this condition occurs, the lower ring of muscle in the oesophagus (referred to equally the lower oesophageal sphincter) develops the disability to relax. The issue of this is that the inlet into the stomach is contracted and no food tin can pass into the breadbasket.

A stricture refers to the tightening and shortening or narrowing of a tube in the body. With reference to the oesophagus, an oesophageal stricture is when the muscle which comprises the oesophagus becomes narrow and tight in structure. This makes it difficult for anything to laissez passer downward the throat and connect to the stomach. Oesophageal strictures can be either benign and prove slow progression, or malignant and bear witness rapid worsening.

Signs and Symptoms of achalasia and stricture

When suffering from achalasia patients often present with the following:

  • Finding difficulty when swallowing food (both solids and liquids)
  • Retained nutrient that is regurgitated and could regurgitate into the lungs at night causing a medical emergency
  • Awareness of discomfort in the chest or a abrupt pain in the breast without cause
  • Heartburn which is not relieved by treatment
  • Weight loss due to lower intake of food

Oesophageal strictures may present an array of symptoms depending on the type and cause, these are potentially as follows:

  • Difficulty when trying to swallow liquid or solids
  • Sensation that nutrient is sticking in the throat
  • Episodes of choking more and more frequently
  • A feeling of called-for along the throat or in the neck

Diagnosis of achalasia and stricture

Achalasia is diagnosed based off symptoms described past the patient, through X-ray studies, with a barium swallow, via oesophageal manometry to measure the muscle part in the oesophagus, using endoscopy where a camera provides a visual paradigm inside the oesophagus directly, and various scans to search for abnormalities or growths.

Strictures can be diagnosed similarly to how achalasia is diagnosed. This is based off described symptoms, X-ray studies with a barium swallow, using endoscopy, and through oesophageal manometry.

Causes of achalasia and stricture

The causes of achalasia are usually genetic and inherited. An abnormality of the immune system can as well cause the body to have an autoimmune response and damage itself

The causes of an oesophageal stricture are usually an inflamed oesophagus acquired by an allergic reaction or problems with the allowed arrangement, gastroesophageal reflux where acrid damages the oesophagus, cancer of the oesophagus, ulcers, medications (such as antibiotics and certain anti-inflammatory drugs), surgical procedures (more specifically, scarring later on surgery), and radiations therapy.

Treatment of achalasia and stricture

Treatment of achalasia can be constructive and include oral medications, oesophageal dilation where the sphincter is stretched by a balloon, injecting Botox directly into the sphincter muscle to relax it, and surgery where the sphincter is cut (oesphagomyotomy).

For the handling of an oesophageal stricture, the general get-to option is oesophageal dilation: a procedure where a balloon is used to widen and open up the area which has narrowed

Table of comparison between achalasia and stricture


Achalasia and oesophageal strictures both involve the oesophagus. Achalasia refers to a tightening of the sphincter muscle, preventing food from inbound the tum. Oesophageal stricture refers to a condition where the bodily muscular tube of the oesophagus becomes tight, shortened and narrowed, preventing food from passing downward through the throat. Both conditions are diagnosed with like tests, many of them overlapping in handling too. Notwithstanding, the mechanism of each status is unique to itself.


Is achalasia a stricture?

Achalasia is not a stricture. Achalasia involves the band-like muscle at the tum inlet which tightens up, whereas oesophageal stricture involves the entire tube-like musculus which makes up the length of the oesophagus narrowing, shortening, and tightening.

What are the three types of achalasia?

There are 3 distinct types of achalasia which are measured and classified using loftier-resolution manometry. This includes measurement of muscle thickness and the wrinkle and relaxation patterns which occur within the muscle layers. The three types can be characterized as follows:

  1. Type 1 (archetype): where there is a level of minimal contraction in the oesophageal area, this is as well referred to every bit minimal oesophageal pressurization
  2. Type two: where there are intermittent phases of panesophageal pressurizations, this is too referred to as oesophageal compression
  3. Type 3 (spastic): where in that location is a presence of early-onset or spastic oesophageal contractions at the distal cease

Each of the three types of achalasia are largely distinct in their response to both medical and surgical handling. It is of high importance to classify which type of achalasia is nowadays in a patient, as this would be of major benefit in the effective choice of treatment and strengthen future research on the status.

What is a stricture?

A stricture refers to the abnormal tightening, shortening or narrowing of a bodily passage. It tin occur in regions such every bit the oesophagus linking to the breadbasket, or passages such as the urethra which provides linkages in the urinary tract where it allows for urine to exit the bladder and and so the trunk. When a stricture occurs in a region such as the urethra, it tin can make urination a struggle to complete. Just equally in the oesophagus, where strictures result in the struggle to eat and/or swallow.

What is an oesophageal stricture?

An oesophageal stricture is the occurrence of abnormal narrowing of the passage from the mouth to the tummy, or the aberrant tightening and shortening thereof. This condition tin result in severe limitations of liquids and foods travelling to the tummy and is frequently experienced aslope the awareness of non being able to swallow or the feeling of having nutrient go stuck in the pharynx region.
