Achalasia is an uncommon motility disorder of the esophagus with an uncertain etiology. Considerable debate exists regarding the most effective treatment for long-term relief of symptoms. For decades, pneumatic dilatation has been the primary treatment option, and surgery was reserved for patients who required repeated dilations or for those who were not willing to undergo the risk of perforation associated with dilatation. Recently botulinum toxin injection of the lower esophageal sphincter has been shown to provide substantial short-term relief from dysphagia; however, its effect only lasts for a short period of time. Recently, minimally invasive surgical techniques have been developed to perform a Heller myotomy effectively with an antireflux procedure. This has become a primary treatment option for many patients. We present a review of the outcome of different therapeutic options of achalasia with a special focus on laparoscopic procedures. 相似文献

Modern management of achalasia 总被引:3,自引:0,他引:3

Opinion statement The goals in the treatment of achalasia are threefold: 1) relieving the symptoms, particularly dysphagia and bland regurgitation;
2) improving esophageal emptying by disrupting the poorly relaxing lower esophageal sphincter (LES); and 3) preventing the
development of megaesophagus. Although achalasia cannot be permanently cured, excellent palliation is available in over 90%
of patients, especially those with pneumatic dilation and laparoscopic Heller myotomy. The efficacy for short- and long-term
therapy seems to be similar when performed by experts. Pneumatic dilation done as an outpatient surgery disrupts the LES muscle
from within by using balloons of progressively larger diameter (3.0, 3.5, and 4.0 cm). Repeat dilations may be required; secondary
severe gastroesophageal reflux disease (GERD) is rare, but approximately 2% of patients will have an esophageal perforation.
A surgical Heller myotomy is now being done laparoscopically through the abdomen that cuts the LES and extends the myotomy
2 to 3 cm onto the stomach. Usually 2 days of hospitalization is required, and patients can normally return to work in 1 to
2 weeks. Severe GERD with esophagitis and peptic stricture is a common complication; therefore, most surgeons combine the
myotomy with an incomplete fundoplication. Medical therapy is much less effective than these invasive procedures. Smooth muscle
relaxants (nitrates and calcium channel blockers) taken immediately before meals improve dysphagia, but side effects and drug
tolerance are common. The injection of botulinum toxin (100 to 200 units) endoscopically into the LES gives short-term relief
of symptoms and improves esophageal emptying. This treatment is most effective in the elderly, as symptom relief can last
up to 1 to 2 years with a single injection. Several studies suggest the most cost-effective management of achalasia is initial
treatment with pneumatic dilation. 相似文献

In general,the treatment methods for esophageal achalasia are largely classified into four groups,including drug therapy using nitrite or a calcium channel blocker,botulinum toxin injection,endoscopic therapy such as endoscopic balloon dilation,and surgery. Various studies have suggested that the most effective treatment of esophageal achalasia is surgical therapy. The basic concept of this surgical therapy has not changed since Heller proposed esophageal myotomy for the purpose of resolution of lower esophageal obstruction for the first time in 1913,but the most common approach has changed from openchest surgery to laparoscopic surgery. Currently,the laparoscopic surgery has been the procedure of choice for the treatment of esophageal achalasia. During the process of the transition from open-chest surgery to laparotomy,to thoracoscopic surgery,and to laparoscopic surgery,the necessity of combining antireflux surgery has been recognized. There is some debate as to which type of antireflux surgery should be selected. The Toupet fundoplication may be the most effective in prevention of postoperative antireflux,but many medical institutions have selected the Dor fundoplication which covers the mucosal surface exposed by myotomy. Recently,a new endoscopic approach,peroral endoscopic myotomy(POEM),has received attention. Future studies should examine the long-term outcomes and whether POEM becomes the gold standard for the treatment of esophageal achalasia. 相似文献

Achalasia: treatment options revisited. 总被引:4,自引:0,他引:4
The aim of all current forms of treatment of achalasia is to enable the patient to eat without disabling symptoms such as dysphagia, regurgitation, coughing or choking. Historically, this has been accomplished by mechanical disruption of the lower esophageal sphincter fibres, either by means of pneumatic dilation (PD) or by open surgical myotomy. The addition of laparoscopic myotomy and botulinum toxin (BTX) injection to the therapeutic armamentarium has triggered a recent series of reviews to determine the optimal therapeutic approach. Both PD and BTX have excellent short term (less than three months) efficacy in the majority of patients. New data have been published that suggest that PD and BTX (with repeat injections) can potentially obtain long term efficacy. PD is still considered the first-line treatment by most physicians; its main disadvantage is risk of perforation. BTX injection is evolving as an excellent, safe option for patients who are considered high risk for more invasive procedures. Laparoscopic myotomy with combined antireflux surgery is an increasingly attractive option in younger patients with achalasia, but long term follow-up studies are required to establish its efficacy and the potential for reflux-related sequelae. 相似文献

AIM:Modified Heller‘s myotomy is still the first choice for achalasia and the assessment of surgical outcomes is usually made based on the subjective sensation of patients.This study was to objectively assess the long-term outcomes of esophageal myotomy for achalasia using esophageal manometry, 24-hour pH monitoring,esophageal scintigraphy and fiberoptic esophagoscopy.METHODS:From February 1979 to October 2000, 176 patients with achalasia underwent modified Heller‘s myotomy, including esophageal myotomy alone in 146 patients, myotomy in combination with Gallone or Dor antirefiux procedure in 22 and 8 patients, respectively. Clinical score,pressure of the lower esophageal sphincter (LES),esophageal clearance rate and gastroesophageal reflux were determined before and i to 22 years after surgery.RESULTS: After a median follow-up of 14 years, 84.5% of patients had a good or excellent relief of symptoms,and clinical scores as well as resting pressures of the esophageal body and LES were reduced compared with preoperative values (P<0.001).However,there was no significant difference in DeMeester score between pre-and postoperative patients(P=0.51).Esophageal transit was improved in postoperative patients, but still slower than that in normal controls. The incidence of gastroesophageal reflux in patients who underwent esophageal myotomy alone was 63.6% compared to 27.3% in those who underwent myotomy and antirefiux procedure (P=-0.087). Three (1.7%) patients were complicated with esophageal cancer after surgery.CONCLUSION: Esophageal myotomy for achalasia can reduce the resting pressures of the esophageal body and LES and improve esophageal transit and dysphagia. Myotomy in combination with antireflux procedure can prevent gastroesophageal reflux to a certain extent,but further randomized studies should be carried out to demonstrate its efficacy. 相似文献

Achalasia is a primary motor disorder of the esophagus, in which esophageal emptying is impaired.Diagnosis of achalasia is based on clinical findings. The diagnosis is confirmed by radiographic, endoscopic,and manometric evaluations. Several treatments for achalasia have been introduced. We searched the PubMed Database for original articles and metaanalyses about achalasia to summarize the current knowledge regarding this disease, with particular focus on different procedures that are used for treatment of achalasia. We also report the Iranian experience of treatment of this disease, since it could be considered as a model for mediumresource countries. Myotomy,particularly laparoscopic myotomy with fundoplication,is the most effective treatment for achalasia.Compared to other treatments, however, the initial cost of myotomy is usually higher and the recovery period is longer. When performing myotomy is not indicated or not possible, graded pneumatic dilation with slow rate of balloon inflation seems to be an effective and safe initial alternative. Injection of botulinum toxin into the lower esophageal sphincter before pneumatic dilation may increase remission rates. However, this needs to be confirmed in further studies. Due to lack of adequate information regarding the role of expandable stents in the treatment of achalasia, insertion of stents does not currently seem to be a recommended treatment. In summary, laparoscopic myotomy can be considered as the procedure of choice for treatment of achalasia. Graded pneumatic dilation is an effective alternative when the performance of myotomy is not possible for any reason. 相似文献

Achalasia cardia is a motility disorder of the esophagus characterized by failure of relaxation of the lower esophageal sphincter.
Nitrates and calcium channel blockers, pneumatic dilatation, botulinum toxin injection and surgical myotomy have been described
in literature as possible management options. We present a patient who presented with achalasia and was co-incidentally diagnosed
to have cryptogenic cirrhosis with portal hypertension and had esophageal varices. This clinical combination precluded the
use of pneumatic dilatation and surgical myotomy. We injected botulinum toxin into the lower esophageal sphincter using a
celiac plexus neurolysis needle under endoscopic ultrasound guidance; the clinical response was good. 相似文献

Results of surgical treatment of achalasia of the esophagus. 总被引:1,自引:0,他引:1
A Csendes 《Hepato-gastroenterology》1991,38(6):474-480
Surgical treatment of patients with achalasia of the esophagus results in dramatic and permanent relief in almost 90% of the patients. The abdominal approach seems to produce more reflux than the thoracic route. There is evidence that extending myotomy more than 10 mm onto the stomach increases reflux. The length of the hypertensive gastroesophageal sphincter is almost 4 cms and an anterior esophagomyotomy of 5 to 6 cms is long enough in these patients. Extending the section 7 to 10 cms proximally would seem to be unnecessary and may provoke more reflux. The mortality rate of the surgical procedure is very low--less than 0.2%. Postoperative complications can occur in almost 4% of them, esophageal leakage being the most dangerous. The most frequent late complication is gastroesophageal reflux, which can occur symptomatically in 10% of the cases and by objective studies in almost 20% of the patients. The addition of antireflux surgery is controversial. If performed, it must be ensured that no obstruction can occur; esophageal emptying in an aperistalsic esophagus can be seriously delayed. Comparative studies suggest that the addition of antireflux surgery gives better results than myotomy alone. Surgeons performing this operative technique should be specialized digestive tract surgeons and familiar with manometric studies. 相似文献

Achalasia is an esophageal motility disorder of unknown cause, characterised by aperistalsis of the esophageal body and impaired lower esophageal sphincter relaxation. Patients present at all ages, primarily with dysphagia for solids/liquids and bland regurgitation. The diagnosis is suggested by barium esophagram or endoscopy and confirmed by esophageal manometry. Achalasia cannot be cured. Instead, our goal is to relieve symptoms, improve esophageal emptying and prevent the development of megaesophagus. The most successful therapies are pneumatic dilation and surgical myotomy. The advantages of pneumatic dilation include an outpatient procedure, minimal pain, return to work the next day, mild if any GERD, and can be performed in any age group and even during pregnancy. Pneumatic dilation does not hinder future myotomy, and all cost analyses find it less expensive than Heller myotomy. Laparoscopic myotomy with a partial fundoplication has the advantage of being a single procedure, dysphagia relief is longer at the cost of more troubling heartburn, and a myotomy may be more effective treatment in adolescents and younger adults, especially men. Over a two year horizon, the clinical success of pneumatic dilation and laparoscopic myotomy are comparable in a recent large European randomised trial. The prognosis for achalasia patients to return to near-normal swallowing and good quality of life are excellent, but few are "cured" with a single treatment and intermittent "touch up" procedures may be required. 相似文献

Achalasia is a motor disorder characterized by esophageal aperistalsis and failure of lower esophageal sphincter relaxation. The cardinal symptoms are dysphagia, food regurgitation and weight loss. The most effective treatments are pneumatic dilation (PD) of the cardia and Heller esophageal myotomy with partial fundoplication. There is still controversy regarding which treatments should be initially done. The aims of this study were to evaluate clinical response and the variables related to good results in both treatments. Ninety‐two patients with achalasia diagnosed by esophageal manometry were randomized to receive either PD or laparoscopic Heller myotomy with partial fundoplication. After the procedure, patients were followed up clinically and submitted to esophageal manometry and pH monitoring. Three months after treatment, 73% of the patients from PD group and 84% of the surgery group had good results (P = 0.19). After 2 years of follow‐up, 54% of the PD group and 60% of the surgery group (P = not significant) were symptom free. Variables related to a good response to PD were a 50% drop in lower esophageal sphincter pressure (LESP) or a LESP <10 mmHg after treatment. Patients over 40 years old with LESP ≤32 mmHg before treatment and a drop in LESP >50% after treatment significantly achieved better responses after surgical treatment when compared with PD. The reflux rate was significantly higher in the PD group (27.7%) compared with the surgery group (4.7%), P = 0.003. We concluded that surgical treatment and PD for achalasia are equally effective even after 2 years of follow‐up. The choice of treatment for achalasia should be based on the following parameters: treatment availability, rate of good results, complication rates, variables related to good responses and also the patient's wish. 相似文献

Achalasia: diagnosis and management. 总被引:5,自引:0,他引:5
M F Vaezi 《Seminars in gastrointestinal disease》1999,10(3):103-112
Achalasia is a primary esophageal motor disorder of unknown cause that produces complaints of dysphagia, regurgitation, and chest pain. The current treatments for achalasia involve the reduction of lower esophageal sphincter (LES) pressure, resulting in improved esophageal emptying. Calcium channel blockers and nitrates, once used as an initial treatment strategy for early achalasia, are now used only in patients who are not candidates for pneumatic dilation or surgery, and in patients who do not respond to botulinum toxin injections. Because of the more rigid balloons, the current pneumatic dilators are more effective than the older, more compliant balloons. The graded approach to pneumatic dilation, using the Rigiflex (Boston Scientific Corp, Boston, MA) balloons (3.0, 3.5, and 4.0 cm) is now the most commonly used nonsurgical means of treating patients with achalasia, resulting in symptom improvement in up to 90% of patients. Surgical myotomy, once plagued by high morbidity and long hospital stay, can now be performed laparoscopically, with similar efficacy to the open surgical approach (94% versus 84%, respectively), reduced morbidity, and reduced hospitalization time. Because of the advances in both balloon dilation and laparoscopic myotomy, most patients with achalasia can now choose between these two equally efficacious treatment options. Botulinum toxin injection of the LES should be reserved for patients who can not undergo balloon dilation and are not surgical candidates. 相似文献

Achalasia is a rare esophageal motility disorder that necessitates the disruption of the lower esophageal sphincter. Patients with achalasia should be evaluated in a systematic, multidisciplinary fashion. Workup should include upper endoscopy, esophagography, and high-resolution manometry. The gold standard for surgical treatment is laparoscopic Heller myotomy with partial fundoplication. Per-oral esophageal myotomy is a novel endoscopic technique that has gained considerable traction over the past decade. The procedure includes the creation of a submucosal tunnel and a selective circular myotomy of the lower esophageal sphincter. Common intra-operative hazards include bleeding within the submucosal tunnel and capnoperitoneum. Significant complications are rare. Patients experience excellent dysphagia relief that is on par with laparoscopic Heller myotomy at moderate-term follow up. Post-operative gastroesophageal reflux disease occurs in greater than one-third of patients, and the vast majority of cases are readily controlled with an anti-secretory medication. Although data is sparse, there is a growing body of literature that supports the long-term durability of per-oral esophageal myotomy. 相似文献

Gastroesophageal reflux disease (GERD) is a chronic disease deteriorating patient's quality of life. With the advent of proton pump inhibitors, treatment failures have decreased considerably. However, surgical therapy offers the potential for cure in more than 90% of patients with GERD. Specific indications for antireflux surgery are: incomplete response to medical therapy, frequent recurrences despite the medical treatment, laryngopharyngeal, and/or respiratory symptoms, and complications of GERD, such as esophageal stricture, erosive esophagitis, esophageal ulcer, and/or Barrett's esophagus. The introduction of laparoscopic surgery in early ninties had a profound impact on many surgical fields, including the treatment of GERD. In this review, laparoscopic Nissen fundoplication is described and controversial topics, such as total vs. partial fundoplication, and the natural history of Barrett's esophagus after antireflux surgery are addressed. 相似文献

Achalasia is a well-defined neuromuscular disorder of esophageal swallowing function characterized by a nonrelaxing lower esophageal sphincter (LES) and aperistalsis of the esophageal body. Peroral endoscopic myotomy (POEM) is a flexible endoscopic approach to perform a selective circular myotomy of the distal esophagus and proximal stomach. More than a thousand cases have been performed worldwide. Most early reports on POEM focus on its feasibility and safety. Emerging long-term series have reported excellent subjective and objective outcomes of dysphagia relief for achalasia. With increasing experience, centers are expanding indications to end-stage achalasia and nonachalasia neuromuscular disorders such as diffuse esophageal spasm and nonrelaxing LES with hypertensive esophageal body contractions. The postoperative gastroesophageal reflux post-POEM is an issue that requires close objective follow-up, as the correlation of subjective reflux symptoms and objective testing in this setting is poor. Few series have indeed reported on equivalent excellent outcomes post-POEM as compared with a laparoscopic myotomy. This early experience with POEM has demonstrated the validity of this new technique in the management of benign disorders of esophageal swallowing. Refinements in technique and decreases in gastroesophageal reflux disease may make this procedure even more desirable, and potentially the first-line therapy in the management of spastic disorders of the esophagus. 相似文献

Gastroesophageal reflux disease (GERD) is a frequent disorder which is expensive to diagnose and treat. Initiating therapy with empiric trial of proton-pump inhibitor is a well established strategy; however, symptoms of GERD do often persist regardless of effective medication. Nowadays, increasing interest concerning the efficacy and safety of chronic acid suppression with proton-pump inhibitors (PPIs), prompts a consideration for GERD treatment strategies related to the basic physiology of the lower esophageal sphincter, including modulation of its tone and ending of spontaneous transient lower esophageal sphincter relaxation, which contributes to reflux. Together, the lower esophageal sphincter and the crural diaphragm represent the major antireflux barrier, protecting the esophagus from reflux of gastric content. In order to prevent the need for enduring PPIs therapy or surgical procedures, substitute therapeutics approaches are being researched. Recently, studies have focused on the response of the respiratory muscles to inspiratory muscle training. As a result, inspiratory muscle training has emerged as a potential alternative for treatment of gastroesophageal reflux. The present report reviews the physiologic factors contributing to GERD, and presents the newly developed therapies that can be applied either alone or in association with available efficient GERD therapy. 相似文献

Use of botulinum toxin as a diagnostic/therapeutic trial to help clarify an indication for definitive therapy in patients with achalasia 总被引:4,自引:0,他引:4
OBJECTIVE: Intrasphincteric injection of botulinum toxin is useful in achalasia but is limited by its short term efficacy. The aim of this study was to evaluate the use of botulinum toxin in selected patients in whom its short duration of action may be useful in guiding therapy before considering more invasive procedures that might not be indicated. METHODS: Over a 3 yr period, botulinum toxin was injected into the lower esophageal sphincter in patients with: 1) symptoms consistent with achalasia but insufficient manometric criteria to make the diagnosis; 2) complex clinical situations in which there were factors in addition to achalasia that may be contributing to the patient's symptoms and that required different treatment; 3) atypical manifestations of achalasia; 4) advanced achalasia in which it was unclear that sphincter-directed therapy (vs esophagectomy) would be of benefit; and 5) after Heller myotomy. Clinical response was assessed mostly by symptom improvement, but in some patients follow-up barium swallow or radioscintigraphy was available. RESULTS: Eleven patients were identified. Ten had complete symptomatic response to the injection. Two patients have undergone subsequent successful pneumatic dilation, one a successful laparoscopic myotomy, and another currently scheduled for surgical myotomy. The only patient without response had advanced achalasia requiring esophagectomy. CONCLUSIONS: Intrasphincteric injection of botulinum toxin into the lower esophageal sphincter is a useful and safe means of guiding therapy in those patients with a variant of achalasia, atypical achalasia, or complex achalasia in which it is unclear that more invasive procedures such as pneumatic dilation or surgical myotomy are the correct therapy. 相似文献

Peroral endoscopic myotomy (POEM) is an emerging minimally invasive procedure for the treatment of achalasia. Due to the improvements in endoscopic technology and techniques, this procedure allows for submucosal tunneling to safely endoscopically create a myotomy across the hypertensive lower esophageal sphincter. In the hands of skilled operators and experienced centers, the most common complications of this procedure are related to insufflation and accumulation of gas in the chest and abdominal cavities with relatively low risks of devastating complications such as perforation or delayed bleeding. Several centers worldwide have demonstrated the feasibility of this procedure in not only early achalasia but also other indications such as redo myotomy, sigmoid esophagus and spastic esophagus. Short-term outcomes have showed great clinical efficacy comparable to laparoscopic Heller myotomy (LHM). Concerns related to postoperative gastroesophageal reflux remain, however several groups have demonstrated comparable clinical and objective measures of reflux to LHM. Although long-term outcomes are necessary to better understand durability of the procedure, POEM appears to be a promising new procedure. 相似文献
