Several drugs are used to treat DES, including nitroglycerin, hyoscine butylbromide, calcium channel blockers, hydralazine, and anti-anxiety medications. Acid suppression therapy, such as proton pump inhibitors, are often the first line therapy. Botulinum toxin, which inhibits acetylcholine release from nerve endings, injected above the lower esophageal sphincter may also be used in the treatment of DES. Small studies have suggested benefit from endoscopic balloon dilation in certain patients, but all of the above have a low percentage of success in treating the condition; whilst the treatments work in some sufferers, it does not work for everyone. In extremely rare cases, surgery may be considered.
Causes of diffuse esophageal spasm are not well understood. It is thought, however, that many cases are caused by uncontrolled brain signals running to nerve endings. Therefore, suppression medication is often the first line therapy such as anti depressants and anti-epileptic medication are prescribed. It has also been reported that very cold or hot beverages can trigger an esophageal spasm. Avoidance therapy benefits some people, but it has not been medically proven.
Nutcracker esophagus is a benign, nonprogressive condition, meaning it is not associated with significant complications. Patients are usually reassured by their physicians that the disease is unlikely to worsen. However, the symptoms of chest pain and dysphagia may be severe enough to require treatment with medications, and rarely, surgery.
The initial step of treatment focuses on reducing risk factors. While weight reduction may be useful in reducing symptoms, the role of acid suppression therapy to reduce esophageal reflux is still uncertain. Very cold and very hot beverages may trigger esophageal spasms.
Medical therapy for nutcracker esophagus includes the use of calcium-channel blockers, which relax the lower esophageal sphincter (LES) and palliate the dysphagia symptoms. Diltiazem, a calcium-channel blocker, has been used in randomized control studies with good effect. Nitrate medications, including isosorbide dinitrate, given before meals, may also help relax the LES and improve symptoms. The inexpensive generic combination of belladonna and phenobarbital (Donnatal and other brands) may be taken three times daily as a tablet to prevent attacks or, for patients with only occasional episodes, as an elixir at the onset of symptoms. Phosphodiesterase inhibitors, such as sildenafil, can be given to reduce symptoms, particularly pain, but small trials have not been able to demonstrate clinical improvement. Finally, trazodone, an antidepressant that reduces visceral sensitivity, has also been shown to reduce chest pain symptoms in patients with nutcracker esophagus.
Endoscopic therapy with botulinum toxin, known also as Botox, can also be used to improve dysphagia which stabilizes unintentional weight loss, but the effect has limited effect on other symptoms, including pain, while also being a temporary treatment lasting a few weeks. Finally, pneumatic dilatation of the esophagus, which is an endoscopic technique where a high-pressure balloon is used to stretch the muscles of the LES, can be performed to improve symptoms, but again no clinical improvement is seen in regards to motility.
It is not clear exactly what causes esophageal spasms. Sometimes esophageal spasms start when someone eats hot or cold foods or drinks. However, they can also occur with eating or drinking. The increased release of acetylcholine may also be a factor, but the triggering event is not known.
In patients who have no response to medical or endoscopic therapy, surgery can be performed. A Heller myotomy involves an incision to disrupt the LES and the myenteric plexus that innervates it. The Heller myotomy is used as a final treatment option in patients who do not respond to other therapies.
A number of endoscopic devices have been tested to treat chronic heartburn.
- Endocinch, puts stitches in the lower esophogeal sphincter (LES) to create small pleats to help strengthen the muscle. However, long-term results were disappointing, and the device is no longer sold by Bard.
- Stretta procedure, uses electrodes to apply radio-frequency energy to the LES. A 2015 systematic review and meta-analysis in response to the systematic review (no meta-analysis) conducted by SAGES did not support the claims that Stretta was an effective treatment for GERD. A 2012 systematic review found that it improves GERD symptoms.
- NDO Surgical Plicator creates a plication, or fold, of tissue near the gastroesophageal junction, and fixates the plication with a suture-based implant. The company ceased operations in mid-2008, and the device is no longer on the market.
- Transoral incisionless fundoplication, which uses a device called Esophyx, may be effective.
Gastroesophageal reflux disease (GERD) affects approximately 40% of adults. Strictures occur in 7 to 23% of patients with GERD who are untreated.
Certain foods and lifestyle are considered to promote gastroesophageal reflux, but most dietary interventions have little supporting evidence. Avoidance of specific foods and of eating before lying down should be recommended only to those in which they are associated with the symptoms. Foods that have been implicated include coffee, alcohol, chocolate, fatty foods, acidic foods, and spicy foods. Weight loss and elevating the head of the bed are generally useful. A wedge pillow that elevates the head may inhibit gastroesophageal reflux during sleep. Stopping smoking and not drinking alcohol do not appear to result in significant improvement in symptoms. Although moderate exercise may improve symptoms in people with GERD, vigorous exercise may worsen them.
The patient is generally sent for a GI, pulmonary, or ENT, depending on the suspected underlying cause. Consultations with a speech therapist and registered dietitian nutritionist (RDN) are also needed, as many patients may need dietary modifications such as thickened fluids.
Both before and after treatment, achalasia patients may need to eat slowly, chew very well, drink plenty of water with meals, and avoid eating near bedtime. Raising the head off the bed or sleeping with a wedge pillow promotes emptying of the esophagus by gravity. After surgery or pneumatic dilatation, proton pump inhibitors are required to prevent reflux damage by inhibiting gastric acid secretion, and foods that can aggravate reflux, including ketchup, citrus, chocolate, alcohol, and caffeine, may need to be avoided.
If it is caused by esophagitis, in turn caused by an underlying infection, it is commonly treated by treating the infection (typically with antibiotics). In order to open the stricture, a surgeon can insert a bougie – a weighted tube used to dilate the constricted areas in the esophagus. It can sometimes be treated with other medications. For example, an H2 antagonist (e.g. ranitidine) or a proton-pump inhibitor (e.g. omeprazole) can treat underlying acid reflux disease.
Sublingual nifedipine significantly improves outcomes in 75% of people with mild or moderate disease. It was classically considered that surgical myotomy provided greater benefit than either botulinum toxin or dilation in those who fail medical management. However, a recent randomized controlled trial found pneumatic dilation to be non-inferior to laparoscopic Heller myotomy.
No cure for the condition as such exists. A number of treatments may provide partial relief:
- Botox injections may temporarily disable the muscle and provide relief for 3-4 months per injection
- Muscle relaxants
- Lorazepam (Ativan), diazepam (Valium) and other benzodiazepines relax the smooth muscle in the throat, slowing or halting contractions. In some people, benzodiazepines may have addictive properties.
- Stress reduction
- High stress levels make these spasms more noticeable
- It is advisable to take note of when your symptoms are at their worst
- Warm fluids
- Hot fluids may be helpful for some people with cricopharyngeal spasm (or other esophageal disorders)
Esophageal spasm or oesophageal spasm is a disorder of esophageal motility. The esophagus is an organ in vertebrates which consists of a fibromuscular tube through which food passes, aided by peristalsis contractions, from the upper esophageal sphincter to the stomach through waves of coordinated muscle contraction, or peristalsis.
There are two types of esophageal spasm:
- Diffuse esophageal spasm (DES), where there is uncoordinated esophageal contractions where several sections of the esophagus can contract at once.
- Nutcracker esophagus (NE) also known as hypertensive peristalsis, where the contractions are coordinated but with an excessive amplitude.
Both conditions can be linked with Gastroesophageal reflux disease (GERD).
When the coordinated muscle contraction are irregular or uncoordinated, this condition may be called diffuse esophageal spasm. These spasms can prevent food from reaching the stomach where food gets stuck in the esophagus. At other times the coordinated muscle contraction is very powerful, which is called nutcracker esophagus. These contractions move food through the esophagus but can cause severe pain.
About 6 to 14 percent of patients who receive a routine barium swallow test of the esophagus are found to have a Schatzki ring.
Ressurance to the patient when no cause can be found.
In case of a cause treat the cause.
Esophageal webs and rings can be treated with endoscopic dilation.
Asymptomatic Schatzki rings seldom worsen over time, and need no treatment.
Symptomatic Schatzki rings may be treated with esophageal dilatation, using bougie or balloon dilators. These have been found to be equally effective. Bougie dilatation involves passage of long dilating tubes of increasing size down the esophagus to stretch the area of narrowing, either over a guidewire passed into the stomach by endoscopy (the "Savary-Gillard" system) or using mercury-weighted dilators (the "Maloney" system). This is usually done with intravenous sedation to reduce discomfort. Dilatation can produce some temporary irritation. A short course of proton pump inhibitor therapy may decrease aggravation by stomach acid reflux into the esophagus. The duration of the benefit of dilation varies, but may be from months to years. Dilation may be repeated if narrowing recurs.
Minor laryngospasm will generally resolve spontaneously in the majority of cases.
Laryngospasm in the operating room is treated by hyperextending the patient's neck and administering assisted ventilation with 100% oxygen. In more severe cases it may require the administration of an intravenous muscle relaxant, such as Succinylcholine, and reintubation.
When Gastroesophageal Reflux Disease (GERD) is the trigger, treatment of GERD can help manage laryngospasm. Proton pump inhibitors such as Dexlansoprazole (Dexilant), Esomeprazole (Nexium), and Lansoprazole (Prevacid) reduce the production of stomach acids, making reflux fluids less irritant. Prokinetic agents reduce the amount of acid available by stimulating movement in the digestive tract.
Spontaneous laryngospasm can be treated by staying calm and breathing slowly, instead of gasping for air. Drinking (tiny sips) of ice water to wash away any irritants that may be the cause of the spasm can also help greatly.
Patients who are prone to laryngospasm during illness can take measures to prevent irritation such as antacids to avoid acid reflux, and constantly drinking water or tea keep the area clear of irritants.
Additionally, laryngospasms can result from hypocalcemia, causing muscle spasms and/or tetany. Na+ channels remain open even if there is very little increase in the membrane potential. This affects the small muscles of the vocal folds.
The standard treatment of food bolus obstruction is the use of endoscopy or fibre-optic cameras inserted by mouth into the esophagus. Endoscopes can be used to diagnose the cause of the food bolus obstruction, as well as to remove the obstruction. Traditional endoscopic techniques involved the use of an overtube, a plastic tube inserted into the esophagus prior to the removal of the food bolus, in order to reduce the risk of aspiration into the lungs at the time of endoscopy. However, the "push technique", which involves insufflating air into the esophagus, and gently pushing the bolus toward the stomach instead, has emerged as a common and safe way of removing the obstruction.
Other tools may be used to remove food boluses. The Roth Net® is a mesh net that can be inserted through the endoscope, and opened and closed from the outside; it can be used to retrieve pieces of obstructed food. Snares, which are normally used to remove polyps can be used to macerate the food causing the obstruction. Dormia baskets, which are metal baskets used to remove stones from the common bile duct in a procedure known as endoscopic retrograde cholangiopancreatography, can be opened and closed from the outside in a similar manner to macerate food and facilitate removal. Forceps used for biopsies can also be employed in a similar manner.
In 2015, a treatment for reflux esophagitis was introduced. It involves a small invasive surgery to place a ring of magnetic titanium beads near the lower esophageal sphincter. It is called a magnetic sphincter augmentation device or MSAD. It was made to prevent GERD by keeping the stomach acid out of the esophagus. Before the implantation of the device, the patients in this study were taking proton pump inhibitors. The pilot study for this device resulted in a treatment that "preserves gastric anatomy" and results in "less severe side effects than traditional antireflux surgery." The patient's that had these devices implanted were given a questionnaire for their GERD Health Related Quality of Life (GERD-HRQL) before implantation. There scores improved after the five years and more than 80% discontinued their proton pump inhibitors. The normalization of esophageal pH was achieved by 70% of the patients in the study. At the end of the study, there were "no reports of death, device erosions, device migrations, device malfunctions, or late-occurring device complications."
The study of esophagitis has focused on reflux esophagitis over the years. However, recently, the study of different subtypes has emerged. Researchers have started to study other causes besides acid reflux. Eosinophilic esophagitis and infectious esophagitis are subtypes that target the lining of the esophagus via infection or immune-mediated inflammatory diseases. Other causes of esophagitis are being studied such as how Crohn's disease, caustic injury, chemotherapy, and radiotherapy can have an effect on the esophagus. It is important to realize that not all upper gastrointestinal tract symptoms are due to gastric reflux and to look at the patient's clinical history before diagnosing and treating the patient. It is important to note that there can be more than one underlying cause to esophagitis.
Treatments for esophagitis include medications to block acid production, to manage pain, and to reduce inflammation. Other treatments include antibiotics and intravenous nutrition.
To treat reflux esophagitis, over the counter antacids, medications that reduce acid production (H-2 receptor blockers), and proton pump inhibitors are recommended to help block acid production and to let the esophagus heal. Some prescription medications to treat reflux esophagitis include higher dose H-2 receptor blockers, proton pump inhibitors, and prokinetics, which help with the emptying of the stomach.
To treat eosinophilic esophagitis, avoiding any allergens that may be stimulating the eosinophils is recommended. As for medications, proton pump inhibitors and steroids can be prescribed. Steroids that are used to treat asthma can be swallowed to treat eosinophil esophagitis due to nonfood allergens. The removal of food allergens from the diet is included to help treat eosinophilic esophagitis.
For infectious esophagitis, a medicine is prescribed based on what type of infection is causing the esophagitis. These medicines are prescribed to treat bacterial, fungal, viral, and/or parasitic infections.
An endoscopy can be used to remove ill fragments. Surgery can be done to remove the damaged part of the esophagus. For reflux esophagitis, a fundooplication can be done to help strengthen the lower esophageal sphincter from allowing backflow of the stomach into the esophagus. As for patients that have a narrowing esophagus, a gastroenterologist can perform a procedure to dilate the esophagus.
Some home remedies and lifestyle changes to help with esophagitis include losing weight, stop smoking, lowering stress, avoid sleeping/lying down after eating, raise your head while laying down, taking medicines correctly, avoiding certain medications, and avoiding foods that cause the reflux that might be causing the esophagitis.
If the disease remains untreated, it can cause scarring and discomfort in the esophagus. If the irritation is not allowed to heal, esophagitis can result in esophageal ulcers. Esophagitis can develop into Barrett's esophagus and can increase the risk of esophageal cancer.
The prognosis for a person with esophagitis depends on the underlying causes and conditions. If a patient has a more serious underlying cause such as a digestive system or immune system issue, it may be more difficult to treat. Normally, the prognosis would be good with no serious illnesses. If there are more causes than one, the prognosis could move to fair.
If there is dysphagia to both solids and liquids, then it is most likely a motility problem. If there is dysphagia initially to solids but progresses to also involve liquids, then it is most likely a mechanical obstruction. Once a distinction has been made between a motility problem and a mechanical obstruction, it is important to note whether the dysphagia is intermittent or progressive. An intermittent motility dysphagia likely can be diffuse esophageal spasm (DES) or nonspecific esophageal motility disorder (NEMD). Progressive motility dysphagia disorders include scleroderma or achalasia with chronic heartburn, regurgitation, respiratory problems, or weight loss. Intermittent mechanical dysphagia is likely to be an esophageal ring. Progressive mechanical dysphagia is most likely due to peptic stricture or esophageal cancer.
When laryngospasm is coincident with a cold or flu, it may be helpful for some sufferers to take acid reflux medication to limit the irritants in the area. If a cough is present, then treat a wet cough; but limit coughing whenever possible, as it is only likely to trigger a spasm. Drink water or tea to keep the area from drying up. Saline drops also help to keep the area moist. Pseudoephederine may also help to clear any mucus that may cause coughing and thereby triggering more spasms.
In an emergency room setting, someone with food bolus obstruction may be observed for a period to see if the food bolus passes spontaneously. This may be encouraged by administering fizzy drinks that release gas, which may dislodge the food.
Glucagon relaxes the lower esophageal sphincter and may be used in those with esophageal food bolus obstruction. There is little evidence for glucagon's effectiveness in this condition, and glucagon may induce nausea and vomiting, but considering the safety of glucagon this is still considered an acceptable option as long it does not lead to delays in arranging other treatments. Other medications (hyoscine butylbromide, benzodiazepines and opioids) have been studied but the evidence is limited.
Historical treatment of food bolus obstruction included administration of proteolytic enzymes (such as meat tenderizers) with the purpose of degrading the meat that was blocked; however, it is possible that these methods may increase the risk of perforation of the esophagus. Other modalities rarely used now include removal of boluses using catheters, and the use of large-bore tubes inserted into the esophagus to forcefully lavage it.
