Abstract
Controversy exists with regard to the optimal treatment for achalasia and whether surveillance for early recognition of late complications is indicated. Currently, surgical myotomy and pneumatic dilation are the most effective treatments for patients with idiopathic achalasia, and a multicenter, randomized, international trial has confirmed similar efficacy of these treatments, at least in the short term. Clinical predictors of outcome, patient preferences and local expertise should be considered when making a decision on the most appropriate treatment option. Owing to a lack of long-term benefit, endoscopic botulinum toxin injection and medical therapies are reserved for patients of advanced age and those with clinically significant comorbidites. The value of new endoscopic, radiologic or surgical treatments, such as peroral endoscopic myotomy, esophageal stenting and robotic-assisted myotomy has not been fully established. Finally, long-term follow-up data in patients with achalasia support the notion that surveillance strategies might be beneficial after a disease duration of more than 10-15 years.

Abstract
OBJECTIVE The purpose of this article is to compare the efficacy of self-expanding metallic stents and pneumatic dilation for the long-term clinical treatment of achalasia. SUBJECTS AND METHODS Patients diagnosed with achalasia (n = 120) were allocated for treatment with pneumatic dilation (n = 30; group A) or a temporary self-expanding metallic stent with a diameter of 20 mm (n = 30; group B), 25 mm (n = 30; group C), or 30 mm (n = 30; group D). Data on clinical symptoms, complications, and long-term clinical outcomes were collected, and follow-up was performed at 6 months and at 1, 3-5, 5-8, 8-10, and more than 10 years after surgery. RESULTS Pneumatic dilation and stent placement were technically successful in all patients. The follow-up at more than 10 years revealed that the clinical remission rate in group D (83.3%) was higher than that in groups A (0%), B (0%), and C (28.6%), and the overall cumulative clinical failure rate in group D (13%) was lower than that in groups A (76.7%), B (53.3%), and C (26.7%). Patients in group D exhibited reduced dysphagia scores and lower esophageal sphincter pressures and had normal levels of barium height and width during the follow-up periods, whereas these markers increased with time in the other groups. The duration of primary patency in group D was also longer than that in groups A, B, and C. CONCLUSION A temporary self-expanding metallic stent with a diameter of 30 mm has superior clinical efficacy for the treatment of achalasia compared with pneumatic dilation or self-expanding metallic stents with diameters of 20 or 25 mm.

Abstract
BACKGROUND Laparoscopic Heller myotomy and Dor fundoplication are now widely performed for achalasia. In patients who have had dilatation in the past, inflammation between the esophageal mucosal and muscular layers may make it difficult to perform myotomy. PURPOSE We investigated the effects of preoperative dilatation on the surgical outcomes. METHOD : One hundred and twelve patients were divided into 2 groups: 37 patients with a past history of preoperative dilatation and 75 patients who had no history of preoperative dilatation. The operating time, intraoperative blood loss, days required to resume postoperative oral intake, postoperative hospital stay, improvement in dysphagia, and incidence of postoperative esophagitis were compared. RESULTS The operating time, intraoperative blood loss, postoperative hospital stay, and improvement of dysphagia were no significant differences between these groups. Furthermore, there were no significant differences in the incidence of postoperative esophagitis. CONCLUSIONS The therapeutic outcome of laparoscopic Heller myotomy and Dor fundoplication is not affected by preoperative pneumatic dilatation.

Abstract
Achalasia is an esophageal motility disorder of unknown cause, characterized 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 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 overall success rate of graded pneumatic dilation is 78%, with women and older patients responding best. Laparoscopic myotomy, usually combined with a partial fundoplication, has an overall success rate of 87%. Young patients, especially men, are the best candidates for surgical myotomy. Botulinum toxin injection into the lower esophageal sphincter and smooth muscle relaxants are usually reserved for older patients or those with co-morbid illness. The prognosis for achalasia patients to return to near normal swallowing is good, but the disease is rarely "cured" with a single procedure and intermittent touch-up procedures may be required.

Abstract
The present study compares the efficacy of a self-expanding metallic stent (SEMS, diameter of 30 mm) and pneumatic dilation for the long-term clinical treatment of achalasia. A total of 155 patients diagnosed with achalasia were allocated for pneumatic dilation (n= 80, group A) or a temporary, 30-mm diameter SEMS (n= 75, group B). The SEMSs were placed under fluoroscopic guidance and removed by gastroscopy 4-5 days after placement. Data on clinical symptoms, complications, and long-term clinical outcomes were collected, and follow-up observations were performed at 6 months and at 1, 3-5, 5-8, 8-10, and >10 years, postoperatively. Pneumatic dilation and stent placement were technically successful in all of the patients. There were no significant differences in technique success, 30-day mortality, or complications between the two groups. The clinical remission rate in group A was significantly lower than that in group B at 1, 1-3, 3-5, 5-8 and, >10 years (P < 0.05), while the cumulative clinical failure rate in group A (66%, 53/80) was higher than that in group B (92%, 6/75). The mean primary patency in group B was significantly longer than that in group A (4.2 vs 2.1 years, respectively; P < 0.001). A temporary, 30-mm diameter SEMS was associated with a better long-term clinical efficacy in the treatment of patients with achalasia as compared with treatment with pneumatic dilation.

Abstract
Secondary achalasia due to submucosal invasion of esophageal squamous cell carcinoma (SCC) is a very rare condition. Here, we report a case of secondary achalasia diagnosed after distal esophagectomy, initially mistaken as primary achalasia. A 51-year-old man presented with progressive dysphagia for 2 months and mild weight loss. A barium swallow study, endoscopy, and manometry showed typical findings of primary achalasia. Pneumatic dilatation was performed, but esophageal perforation occurred as a complication. During surgical repair, no abnormalities around distal esophagus were found, and intraoperative esophageal biopsy revealed only inflammatory cells. During the following 8 months, the patient suffered from dysphagia caused by recurrent esophageal obstruction several times although of repeated balloon dilatation and esophageal stent insertion. Finally, he received a distal esophagectomy. The postoperative pathology revealed SCC at the distal esophagus and esophagogastric junction.

Abstract
OBJECTIVE Pneumatic dilatation (PD) has been widely used in the treatment of primary achalasia. The aim of this study was to evaluate the effectiveness of PD and its predictive factors in Japanese patients with primary achalasia. METHODS Fifty-five consecutive patients were treated using PD (Rigiflex balloon dilator). Diagnosis was established through radiographic and/or esophageal manometry. All patients underwent a pre-designed clinical evaluation prior to and 6 months after PD treatment. We defined success of PD as 6 months or more of clinical remission, with a total score (0-4) <or=2, a decrease in the total score >or=1 and the score for each item <or=1. Possible predictive factors to response were analyzed. RESULTS Successful PD was achieved in 41 of 55 (74.5%) patients. The median age (58.0 years) in the successful group was significantly older than in the failure group (37.5 years), but there were no differences in other factors between the groups. When the cut-off value was set at 40 years of age, the success rate of PD in the >40-year age group was 85.7%, while the <40-year age group achieved a rate of only 38.5%. Multivariate logistic regression analysis also demonstrated that older age was the only independent factor associated with the success of PD. There was no perforation related to PD. CONCLUSIONS PD is a safe and effective treatment for achalasia, particularly in older patients who experience a better outcome than younger patients.

Abstract
Esophageal achalasia is a rare neurodegenerative disease of the esophagus and the lower esophageal sphincter that presents within a spectrum of disease severity related to progressive pathological changes, most commonly resulting in dysphagia. The pathophysiology of achalasia is still incompletely understood, but recent evidence suggests that degeneration of the postganglionic inhibitory nerves of the myenteric plexus could be due to an infectious or autoimmune mechanism, and nitric oxide is the neurotransmitter affected. Current treatment of achalasia is directed at palliation of symptoms. Therapies include pharmacological therapy, endoscopic injection of botulinum toxin, endoscopic dilation, and surgery. Until the late 1980s, endoscopic dilation was the first line of therapy. The advent of safe and effective minimally invasive surgical techniques in the early 1990s paved the way for the introduction of laparoscopic myotomy. This review will discuss the most up-to-date information regarding the pathophysiology, diagnosis, and treatment of achalasia, including a historical perspective. The laparoscopic Heller myotomy with partial fundoplication performed at an experienced center is currently the first line of therapy because it offers a low complication rate, the most durable symptom relief, and the lowest incidence of postoperative gastroesophageal reflux.

Abstract
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 meta-analyses 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 medium-resource 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.

Abstract
BACKGROUND Achalasia is an uncommon illness affecting 1 per 100,000 patients a year. It encompasses a rare, primary motor disorder of the distal esophagus. METHODS Over the period 1998-2006, 115 patients underwent various treatments for achalasia; the subgroup of seniors consisted of 26 patients. Six patients of these (age 69.7 y) underwent a modified Heller cardiomyotomy due to failure of previous endoscopic interventions. Standard esophageal manometry and 24 hour pH metry were performed pre- and postoperatively. RESULTS Six senior patients with achalasia underwent a laparoscopic Heller myotomy. Average preoperative tonus of the LES was 55 mmHg, postoperative tonus of the LES decreased to 11 mmHg. We performed Toupet partial fundoplication in all patients; no microperforation of the esophagus was found in the preoperative esophagoscopy. We recorded minimal pathological gastroesophageal reflux in pH metry - the average preoperative DeMeester score was 8, postoperatively 10.5. Prolonged dysphagia was not present in any patient--preoperative GIQLI score was 94, postoperative score was 106. There was no mortality or morbidity in the group of the operated patients. CONCLUSION Our operational results and postoperative follow-up show that laparoscopic Heller myotomy with Toupet partial fundoplication is a safe and effective treatment and can be recommended as the method of first choice for senior patients with no contraindication for laparoscopic operation.

Abstract
To prospectively evaluate the long-term clinical safety and efficacy of a newly designed self-expanding metallic stent (SEMS) in the treatment of patients with achalasia. Seventy-five patients with achalasia were treated with a temporary SEMS with a 30-mm diameter. The SEMSs were placed under fluoroscopic guidance and removed by gastroscopy 4–5 days after stent placement. Follow-up data focused on dysphagia score, technique and clinical success, clinical remissions and failures, and complications and was performed at 6 months, 1 year, and within 3 to 5 years, 5 to 8 years, 8 to 10 years, and >10 years postoperatively. Stent placement was technically successful in all patients. Complications included stent migration (n = 4, 5.33%), chest pain (n = 28, 38.7%), reflux (n = 15, 20%), and bleeding (n = 9, 12%). No perforation or 30-day mortality occurred. Clinical success was achieved in all patients 1 month after stent removal. The overall remission rates at 6 months, 1, 1–3, 3–5, 5–8, 8–10, and >10 year follow-up periods were 100%, 96%, 93.9%, 90.9%, 100%, 100%, and 83.3%, respectively. Stent treatment failed in six patients, and the overall remission rate in our series was 92%. The median and mean primary patencies were 2.8 ± 0.28 years (95% CI: 2.25–3.35) and 4.28 ± 0.40 years (95% CI: 3.51–5.05), respectively. The use of temporary SEMSs with 30-mm diameter proved to be a safe and effective approach for managing achalasia with a long-term satisfactory clinical remission rate.

Abstract
BACKGROUND Although rare, esophageal achalasia is the best described primary esophageal motility disorder. Commonly used treatments are endoscopic botulin toxin injection (EBTI), endoscopic balloon dilation (EBD), and surgical myotomy with or without a fundoplication; however, reported outcomes mostly come from cohort studies. OBJECTIVE To summarize and compare the safety and efficacy of endoscopic and surgical treatments for esophageal achalasia. METHODS A systematic electronic Medline literature search of articles on esophageal achalasia. Treatment options reviewed included EBTI, EBD, and surgical myotomy using open and minimally invasive techniques. Main outcome measures were frequency of symptom relief, prevalence of post-treatment gastroesophageal reflux (GER), and complications. Outcome probability was estimated using weighted averages of the sample prevalence in each study, with weights equal to the number of patients. Outcomes, within or across studies, were compared using meta-analysis and meta-regression, respectively. RESULTS A total of 105 articles reporting on 7855 patients were selected, tabulated and reviewed. Symptom relief after EBD was better than after EBTI (68.2% vs. 40.6%; OR 3.4; 95% CI, 1.2-9.8; P = 0.02), and the need for additional therapy was greater for patients receiving EBTI (46.6% vs. 25%; OR, 2.6; 95% CI, 1.05-6.5; P = 0.04). Laparoscopic myotomy, when combined with an antireflux procedure, provided better symptom relief (90%) than all endoscopic and other surgical approaches and a low complication rate (6.3%). The incidence of postoperative GER was lower when a fundoplication was added to a laparoscopic myotomy (31.5% without a fundoplication vs. 8.8% with; OR, 6.3; 95% CI, 2.0-19.4; P = 0.003). CONCLUSIONS EBD is superior to EBTI. Laparoscopic myotomy with fundoplication was the most effective surgical technique and can be considered the operative procedure of choice.

Abstract
OBJECTIVES To compare in a prospective, randomized trial the long-term results of laparoscopic Heller myotomy plus Dor fundoplication versus laparoscopic Heller myotomy plus floppy-Nissen for achalasia. SUMMARY BACKGROUND DATA Anterior fundoplication is usually performed after Heller myotomy to control GER; however, the incidence of postoperative GER ranges between 10% and 30%. Total fundoplication may aid in reducing GER rates. METHODS From December 1993 to September 2002, 153 patients with achalasia underwent Heller laparoscopic myotomy plus antireflux fundoplication. Of these, 9 were excluded from the study. The remaining 144 patients were randomly assigned to 2 treatment groups: Heller laparoscopic myotomy plus anterior fundoplication (Dor procedure) or Heller laparoscopic myotomy plus total fundoplication (floppy-Nissen procedure). The primary end point was incidence of clinical and instrumental GER after a minimum of 60 months follow-up. The secondary end point was recurrence of dysphagia. Follow-up clinical assessments were performed at 1, 3, 12, and 60 months using a modified DeMeester Symptom Scoring System (MDSS). Esophageal manometry and 24-hour pH monitoring were performed at 3, 12, and 60 months postoperative. RESULTS Of the 144 patients originally included in the study, 138 were available for long-term analysis: 71 (51%) underwent antireflux fundoplication plus a Dor procedure (H + D group) and 67 (49%) antireflux fundoplication plus a Nissen procedure (H + N group). No mortality was observed. The mean follow-up period was 125 months. No statistically significant differences in clinical (5.6% vs. 0%) or instrumental GER (2.8% vs. 0%) were found between the 2 groups; however, a statistically significant difference in dysphagia rates was noted (2.8% vs. 15%; P < 0.001). CONCLUSIONS Although both techniques achieved long-term GER control, the recurrence rate of dysphagia was significantly higher among the patients who underwent Nissen fundoplication. This evidence supports the use of Dor fundoplication as the preferred method to re-establish GER control in patients undergoing laparoscopic Heller myotomy.

Abstract
Pneumatic dilation (PD) has been widely used in the treatment of idiopathic achalasia with a 70-90% response. The aim of this study was to evaluate the effectiveness of PD and its predictive factors by means of clinical assessment. In addition, we evaluated its safety and the need for subsequent surgical intervention. Fifty-six patients were treated with a Witzel dilator. The response was evaluated at medium (1-5 years) and long term (>5 years). Diverse possible predictive factors to response were analyzed. After the first PD, 85.7% of the 56 patients improved and passed from clinical stage II-III to clinical stage 0-I (P < 0.005). After the second dilation, 84.6% of the patients (13) passed to clinical stage 0-I (P < 0.05). Only patients who were not young (>40 years) avoided a second dilation and/or surgery (P < 0.001). During the first 5 years of follow-up, 80% of patients maintained their response; this percentage decreased to 58% after 10 years. PD therapy of achalasia is a safe technique, with few adverse effects (4% perforations and 10% gastroesophageal reflux). It offers a medium-term response of 80% and long-term response of around 60%. Age was the only predictive response factor.

Abstract
Only a few studies have been performed comparing subjective symptom improvements with objective improvement in esophageal emptying after pneumatic dilation (PD), and discrepancy existed. We evaluated whether esophagogram measurements adds to the traditional subjective symptoms scores in assessing achalasia patients after PD. We enrolled 32 new patients with achalasia who received endoscope-guided PD treatment between January 1998 and June 2004. Postdilation investigations were performed by using esophageal emptying on esophagogram prospectively in a blinded manner, along with symptom scores before and after PD at the initial investigation, 6 weeks later, and every 1 year thereafter. Our results showed that seven patients who noted complete relief showed less than 50% improvement in barium column height and esophageal diameter. There was no linear correlation between the degree of patient symptom improvement and esophageal emptying measured by esophagogram (r = 0.181, P = 0.322). A trend of association existed in the relationship between clinical remissions and initial post-PD esophageal emptying improvement (P = 0.067). In summary, the association between the post-PD symptom score improvement and degrees of esophageal emptying may be hampered by the small sample size in the current study. An additional objective parameter like esophagogram to the subjective symptom scores may be more optimal in assessing clinical remissions.

Abstract
Our institution introduced laparoscopic surgery for esophageal achalasia in 2001. The present report summarizes 15 cases of achalasia treated with laparoscopic Heller myotomy and anterior fundoplication according to the method of Dor, and we have investigated the therapeutic effects on specific symptoms such as dysphagia, reflux, and chest pain. From February 2001 through January 2007, the laparoscopic Heller-Dor operation was performed in 15 patients, including 7 men and 8 women. Achalasia was classified morphologically on esophagography as spindle type in 11 cases, flask type in 3 cases and sigmoid type in 1 case. The degree of esophageal dilatation was classified as grade I in 8 cases, grade II in 6 cases, and grade III in 1 case. Dysphagia was the main symptom and was present in all cases. The mean disease duration was 4.3 years (range, 5 months to 20 years), and the mean weight loss was 4.2 kg. All patients underwent endoscopic dilatation preoperatively. Intraoperative blood loss ranged from 0 to 100 mL (mean, 21 mL). Adequate Heller myotomy was considered more than 6 cm and more than 3 cm in the esophagus and the stomach, respectively. Injury to the esophageal mucosa occurred during the myotomy in 3 cases but could be repaired in all cases during the laparoscopic procedure. All patients reported an excellent level of satisfaction postoperatively. In conclusion, the laparoscopic Heller-Dor operation for esophageal achalasia is a useful procedure because the postoperative satisfaction level of patients is excellent. Despite the risk of mucosal injury, adequate Heller myotomy should be achieved to obtain a good prognosis. It is, therefore, of utmost importance to obtain mastery over the surgical technique to repair any mucosal injury that might occur.

Abstract
PURPOSE To compare the long-term clinical effectiveness of fluoroscopically guided double and endoscopically guided single balloon dilations in esophageal achalasia. MATERIALS AND METHODS Thirty-two fluoroscopically guided balloon dilations were performed in 21 patients (group A) and 48 endoscopically guided balloon dilations were performed in 37 patients (group B). The double balloon dilation technique (10 + 20-mm, 15 + 20-mm or 20 + 20-mm in diameter), with preceding single balloon dilation (10, 15, or 20-mm in diameter), was used in group A, whereas the single balloon dilation technique (30, 35, or 40-mm in diameter) with gradually increased internal pressure was used in group B. Technical success, clinical success, complications, and primary/secondary patency rates were compared between the two groups. RESULTS All procedures were technically successful without esophageal perforation. Clinical success was achieved in 97% (31/32) and 92% (44/48) of balloon dilations in groups A and B, respectively. The symptomatic improvement in dysphagia was significantly higher in group A than in group B. Incidence of complications was the same (18.8%) in both groups. Group A showed significantly longer primary and secondary patency periods than did group B (P < 0.05). CONCLUSION Fluoroscopically guided double balloon dilation has greater long-term effectiveness than endoscopically guided single balloon dilation in the treatment of esophageal achalasia.

Abstract
BACKGROUND Considerable information has been gathered on the functional organization of enteric neuronal circuitries regulating gastrointestinal motility. However, little is known about the neuropathophysiological mechanisms underlying gastrointestinal motor disorders. AIM To analyse the most important pathological findings, clinical implications and therapeutic management of idiopathic enteric neuropathies. METHODS PubMed searches were used to retrieve the literature inherent to molecular determinants, pathophysiological bases and therapeutics of gastrointestinal dysmotility, such as achalasia, gastroparesis, chronic intestinal pseudo-obstruction, Hirschsprung's disease and slow transit constipation, to unravel advances on digestive disorders resulting from enteric neuropathies. RESULTS Current data on molecular and pathological features of enteric neuropathies indicate that degenerative and inflammatory abnormalities can compromise the morpho-functional integrity of the enteric nervous system. These alterations lead to a massive impairment in gut transit and result in severe abdominal symptoms with associated high morbidity, poor quality of life for patients and established mortality. Many pathophysiological aspects of these severe conditions remain obscure, and therefore treatment options are quite limited and often unsatisfactory. CONCLUSIONS This review of enteric nervous system abnormalities provides a framework to better understand the pathological processes underlying gut dysmotility, to translate this knowledge into clinical management and to foster the development of targeted therapeutic strategies.

Abstract
Achalasia and gastroesophageal reflux disease (GERD) represent diverse physiologic disorders both of which result from lower esophageal sphincter (LES) dysfunction. Fortunately, both diseases are benign and amenable to surgically corrective therapies. Achalasia is characterized by destruction of the smooth muscle ganglion cells of the myenteric plexus (Auerbach) resulting in motor dysfunction, incomplete LES relaxation, and progressive esophageal dilation. GERD is frequently characterized by hypotonia or shortening of the LES. Local anatomical derangements such as a hiatal hernia (eg, sliding type I hernia) can predispose to GERD. Other predisposing factors for GERD include obesity, smoking, alcohol, and pregnancy. Transient LES relaxation is the most significant factor in the development of GERD. Transient LES relaxations last from 10 to 45 seconds and are not related to swallowing. The diagnostic workup of achalasia and GERD may include barium esophagram, upper gastrointestinal endoscopy, pH monitoring, and esophageal manometry. The different medical treatment options for achalasia comprise pharmacologic treatment, botulinum toxin, and balloon dilation. Surgical interventions include Heller myotomy, which is usually combined with a partial fundoplication. GERD is managed by treating the predisposing factors, using medications (ie, anatacids or proton pump inhibitors) and surgery (ie, fundoplication). Recently, endoluminal therapy has been employed in the treatment of GERD with promising short-term results.

Abstract
AIM/BACKGROUND Achalasia may be associated with extraesophageal dysmotility. However, this relation is still poorly understood. In the present study, we used noninvasive real-time ultrasonography to examine the motility function of the gallbladder in the patients with achalasia. MATERIALS AND METHODS Thirty-three achalasic patients and 33 healthy volunteers were included in the study. All subjects were investigated after 12 hours of fasting and 30 minutes after a standard test meal. Premeal and postmeal gallbladder volumes were used for calculation of the ejection fraction of the gallbladder and fasting gallbladder volume. RESULTS The mean fasting volume (18.52+/-1.45 vs. 24.63+/-1.84 cm; P<0.05) and ejection fractions of gallbladder (35.84+/-4.12 vs. 54.47+/-2.47; P<0.05) in the patients with achalasia were lower than the control group. CONCLUSIONS Such a finding may confirm the possible extraesophageal extension of primary achalasia. Achalasic patients have smaller gallbladders than do others. It could be speculated that it is congenital and/or achalasic patients' gallbladder has incomplete relaxation (as in the lower esophageal sphincter of the achalasia).

Abstract
Idiopathic achalasia is a primary esophageal motor disorder characterized by esophageal aperistalsis and abnormal lower esophageal sphincter (LES) relaxation in response to deglutition. It is a rare disease with an annual incidence of approximately 1/100,000 and a prevalence rate of 1/10,000. The disease can occur at any age, with a similar rate in men and women, but is usually diagnosed between 25 and 60 years. It is characterized predominantly by dysphagia to solids and liquids, bland regurgitation, and chest pain. Weight loss (usually between 5 to 10 kg) is present in most but not in all patients. Heartburn occurs in 27%-42% of achalasia patients. Etiology is unknown. Some familial cases have been reported, but the rarity of familial occurrence does not support the hypothesis that genetic inheritance is a significant etiologic factor. Association of achalasia with viral infections and auto-antibodies against myenteric plexus has been reported, but the causal relationship remains unclear. The diagnosis is based on history of the disease, radiography (barium esophagogram), and esophageal motility testing (esophageal manometry). Endoscopic examination is important to rule out malignancy as the cause of achalasia. Treatment is strictly palliative. Current medical and surgical therapeutic options (pneumatic dilation, surgical myotomy, and pharmacologic agents) aimed at reducing the LES pressure and facilitating esophageal emptying by gravity and hydrostatic pressure of retained food and liquids. Although it cannot be permanently cured, excellent palliation is available in over 90% of patients.

Abstract
BACKGROUND Little is known about symptom characteristics of treated achalasia patients and their effect on health-related quality-of-life (HRQoL). AIMS To examine clinical remission, achalasia-associated symptoms and HRQoL in treated achalasia patients. METHODS The Eckardt clinical symptom score, RAND-36 and a disease-specific HRQoL questionnaire were sent to 171 treated achalasia patients. RESULTS 76.6% of the patients returned their questionnaire. 44.9% of them were not in symptomatic remission. Prevalence of frequent dysphagia (at least daily) and chest pain (at least weekly) was 46% and 38%, respectively. Achalasia patients had lower general HRQoL scores than control subjects (all RAND-36 subscales, except health change; P < or = 0.002). Patients with frequent symptoms of chest pain and dysphagia showed lower HRQoL than patients with less frequent symptoms on three RAND-36 subscales (pain, social functioning and general health perceptions; P < 0.003). Patients in clinical remission showed higher HRQoL than patients who were not, however HRQoL in the 'remission group' remained significantly impaired as compared to controls (all RAND-36 subscales except emotional role limitations and mental health; P < 0.001). CONCLUSIONS Many achalasia patients remain severely symptomatic after treatment and have decreased HRQoL. Frequent symptoms are associated with lower HRQoL. Patients in clinical remission show substantially improved, but not restored HRQoL.

Abstract
BACKGROUND Recollection of preoperative symptom frequency and severity may change postoperatively, thus invalidating longitudinal studies. This study was undertaken to compare symptoms of achalasia before myotomy to patients' postoperative recollection of premyotomy symptoms. METHODS A total of 173 patients, 54% male, of median age 48 years, have undergone laparoscopic Heller myotomy and have been followed through a prospectively maintained registry. Preoperatively, patients scored the frequency and severity of their symptoms on a Likert scale: 0 (never/very bothersome) to 10 (always/very bothersome). Similarly, after laparoscopic Heller myotomy, patients scored the frequency and severity of their symptoms, and re-scored their preoperative symptoms. Data are presented as median, mean +/- SD. RESULTS Before myotomy, dysphagia, regurgitation, choking, chest pain, vomiting, and heartburn were particularly notable; symptom scores nearly globally improved after myotomy (p < 0.05 for all, Wilcoxon matched pairs test), especially obstructive symptoms. Postmyotomy recollection of premyotomy symptom frequency and severity was neither substantively nor consistently different from premyotomy scoring. CONCLUSIONS Before myotomy, patient symptom scores reflected the deleterious impact of achalasia. After myotomy, patient symptom scores dramatically improved, reflecting the favorable impact of laparoscopic Heller myotomy. Even years after myotomy, patient recollection of premyotomy symptom severity and frequency is very accurate and supports longitudinal studies of symptom improvement after myotomy.

Abstract
The incidence and prevalence of achalasia is 0.6/100,000 people per year and 1/10,000, respectively. It is difficult then for one center to accumulate a large cohort of patients. One study (Gut 33:1011,1992) described the presenting symptoms in only 38 patients. To approach this problem differently, we used the internet to access a larger patient population. Using search engines at Google and Yahoo, Inc., we identified achalasia support groups. We examined the most populated support group (YSG) and assembled the exchanged messages into 4 categories: support, symptoms, treatment, and diagnosis. Next, a survey modeled after a previous study (ibid) was composed and posted on a university-sponsored Web site for March 2003, advertised to YSG members, and then removed from the server. The results were entered into a database and analyzed. There were 6 support groups identified; 1 was foreign. The most populated site was the Yahoo, Inc., group with 298 active members. We analyzed the 3,222 messages posted from October 6, 2002 through October 5, 2003. The message composition was as follows: 67% support, 16% symptoms, 12% treatment, and 5% diagnosis. Of 298 Yahoo site members, we had 88 respondents to the survey from 9 countries. The data from 83 were analyzed (5 were not completed). Respondents were 66 women (55%), 29 men (24%), and 5 non-gender-identified respondents. They ranged in age from 6 to 72 years at time of diagnosis. In the 83 respondents, dysphagia symptoms were reported by 98%, regurgitation by 68%, chest pain by 81%, weight loss by 69%, and epigastric pain by 67%, similar to those reported in the study cited in Gut. The modalities used to evaluate these achalasia patients were as follows: 83% had monometry, 87% had radiography, and 89% had endoscopy. The mean time from symptom onset to diagnosis was 5 years. The treatments attempted on this population were balloon dilatation in 57%, botulinum toxin injection (Botox) in 8%, myotomy in 12%, by lifestyle/diet modification in 12%, and other treatments in 11%. We believe that the Internet can provide physician-researchers with useful information about common and uncommon diseases on a global basis. The Internet allows patients to voice concerns that they may not freely express to their doctor and provides a modality to collect data from a larger number of patients than may be available at any single institution.

Abstract
OBJECTIVE Subjective assessment of primary achalasia is not accurate. We aimed to study the utility of surface area of barium retention in the objective assessment of these patients. METHODS Subjective and objective esophageal functions of 99 patients with primary achalasia were evaluated initially and 43 of them were reevaluated 1 month after balloon dilation. RESULTS Before dilation: Ninety-nine patients were enrolled. Forty-one of them were male. The mean age was 37.5+/-15.3 years. The mean score, resting lower esophageal sphincter pressure, height, surface and volume of barium retention at 5 min were 8.03+/-3.1, 59.1+/-20 mmHg, 9.9+/-4.9 cm, and 23.6+/-13.9 cm and 53.2+/-47.7 cm, respectively. Surface area at 5 min had best correlation and predictive value for resting lower esophageal sphincter pressure. After dilation: Forty-three of 99 patients were reevaluated after balloon dilation. The mean age was 36.8+/-13.6 years. Seventeen of them were male. Mean score, resting lower esophageal sphincter pressure, height, surface area and volume of barium retention at 5 min dropped significantly after dilation. Surface area at 5 min had best correlation and predictive value for lower esophageal sphincter pressure. CONCLUSIONS Surface area of barium retention at 5 min is an accurate objective tool to assess patients with primary achalasia. It is cheap and easy to perform; therefore, it could be used more frequently in postdilation follow-up.

Abstract
Esophageal achalasia is an infrequent motility disorder characterized by a progressive stasis and dilation of the oesophagus; with subsequent risk of aspiration, weight loss, and malnutrition. Although the treatment of achalasia has been traditionally based on a surgical approach, especially with the introduction of laparoscopic techniques, there is still some space for a medical approach. The present article reviews the non-surgical therapeutic options for achalasia.

Abstract
BACKGROUND Pneumatic dilatation is the first line therapy in achalasia, but half of patients relapse within 5 years of therapy and require further dilatations. AIM To assess whether botulinum toxin injection before pneumatic dilatation is superior to pneumatic dilatation alone in achalasia patients. METHODS Newly diagnosed achalasia patients were randomly assigned to receive botulinum toxin 1 month before pneumatic dilatation (botulinum toxin-pneumatic dilatation group: 27 patients with median age of 38) or to undergo pneumatic dilatation alone (pneumatic dilatation group: 27 patients with median age of 30). Response to therapy was assessed by clinical and objective methods at various intervals. RESULTS One-year remission rate of patients in botulinum toxin-pneumatic dilatation group was 77% compared with 62% in pneumatic dilatation group (P = 0.1). In pneumatic dilatation group, the oesophageal barium volume significantly (P < 0.001) decreased at 1 month, but this reduction did not persist over 1-year follow-up. Botulinum toxin-pneumatic dilatation group showed a significant (P < 0.001) reduction in barium volume at the various times intervals post-treatment. In the botulinum toxin-pneumatic dilatation group, 10/11 (91%) patients over 40 were in remission at 1 year, comparing with only five of nine (55%) cases in pneumatic dilatation group (P = 0.07). CONCLUSION Injection of botulinum toxin before pneumatic dilatation does not significantly enhance the efficacy of pneumatic dilatation.

Abstract
BACKGROUND A standard procedure for the treatment of achalasia remains to be established. We assessed the usefulness of a laparoscopic Heller myotomy with a Toupet fundoplication (LHT). METHODS LHT was performed in 30 patients (12 men, 18 women; mean age, 41.8 y) who had esophageal achalasia with severe dysphagia. Caution was exercised when the esophagus was pulled downward and straightened. Symptoms and esophageal function were evaluated before and after surgery. RESULTS The esophagus was straightened surgically in 22 (88%) of 25 patients with esophageal curvature on preoperative esophagography. The dysphagia score decreased to 1.7 +/- 1.2 (mean +/- SD) points from a preoperative value of 10. The lower esophageal sphincter pressure decreased significantly. Two patients (7%) had esophageal diverticula as postoperative sequelae. Pathologic acid reflex was noted in 3 patients (12%). CONCLUSIONS LHT is a useful procedure for straightening the esophagus, reducing lower esophageal sphincter pressure, and relieving dysphagia in patients with achalasia.

Abstract
BACKGROUND Achalasia, an oesophageal motor disease, is associated with functional oesophageal obstruction. Food stasis can predispose for oesophagitis. Treatment aims at lowering of the lower oesophageal sphincter pressure, enhancing the risk of gastro-oesophageal reflux. Nevertheless, the incidence of oesophagitis after achalasia treatment is unknown. AIM To investigate the incidence and severity of oesophagitis in achalasia patients treated with pneumatic dilatation. METHODS A cohort of 331 patients with achalasia were treated with pneumatic dilatation and followed. Oesophagitis and stasis were assessed by endoscopy and inflammation was graded by histology. RESULTS 251 patients were followed for a mean values of 8.4 years (range: 1-26). The average number of endoscopies with biopsy sample sets per patient was 4 (range: 1-17). Three patients had no histological signs of oesophagitis throughout follow-up, 139 had oesophagitis grade 1, 49 oesophagitis grade 2 and 60 grade 3. Specialized intestinal metaplasia was found in 37 patients. The association between endoscopic food stasis and histological inflammation was significant. The association between endoscopic signs of oesophagitis and histological inflammation was poor. CONCLUSIONS Forty percent of the achalasia patients develop chronic active or ulcerating oesophagitis after treatment. Inflammation was associated with food stasis. Because the sensitivity of endoscopy to detect inflammation is low, surveillance endoscopy with biopsy sampling and assessment of stasis is warranted to detect early neoplastic changes.

Abstract
INTRODUCTION In esophageal achalasia, pneumatic dilations (PD) provide short-term and long-term remission rates of 60-90% and 40-50%, respectively. The aim of this study was to evaluate the long-term efficacy of repeated PD as long-term maintenance therapy. PATIENTS AND METHODS From 1992 to 2004, 150 patients with esophageal achalasia treated by PD were included in this retrospective study (78 males, mean age 57 +/- 20 yr). PD were performed until remission was achieved (symptom score < or = 3, each item < 2) and subsequently when symptomatic recurrence occurred. A standardized symptoms questionnaire was sent to patients lost to follow-up. Results are expressed as mean +/- SD. RESULTS Initial remission was achieved in 137 of 150 (91.3%) patients with 2.67 +/- 1.59 dilations [range 1-12]. Failure and perforation rates were 7.3% (n = 11) and 1.3% (n = 2), respectively. After initial remission, 48 of 137 (35%) patients had recurrent symptoms; the probability to be in remission at 5 and 10 yr was 67% and 50%, respectively. At the end of follow-up (45 +/- 38 months, ext. 2-144) 108 of 137 (78.8%) patients were in remission. Among 112 patients whose symptoms could be treated by repeated PD (per protocol analysis), 108 (96.4%) were in remission (3.5 +/- 2.1 PD, ext. 2-12). In this group, the probability of being in remission after repeated PD at 5 and 10 yr was 96.8% and 93.4%, respectively. No pretherapeutic factor influenced long-term remission rate. The overall prevalence of gastroesophageal reflux was 34.7%. CONCLUSION One-third of the patients with esophageal achalasia treated by PD will experience symptomatic recurrence during a 4-yr period. Long-term remission can be achieved in virtually all the patients treated by repeated PD according to an "on-demand" strategy based on symptom recurrence.

Abstract
Background Achalasia is a well-characterized esophageal motor disorder but the rarity of the disease limits performing large studies on its demographic and clinical features. Methods Prospectively, 213 achalasia patients (110 men and 103 women) were enrolled in the study. The diagnosis established by clinical, radiographic, and endoscopic as well as manometry criteria. All patients underwent a pre-designed clinical evaluation before and within 6 months after the treatment. Results Solid dysphagia was the most common clinical symptom in men and women. Chest pain was the only symptom which was significantly different between two groups and was more complained by women than men (70.9% vs. 54.5% P value= 0.03). Although the occurrence of chest pain significantly reduced after treatment in both groups (P < 0.001), it was still higher among women (32% vs. 20.9% P value= 0.04). In both sexes, chest pain did not relate to the symptom duration, LES pressure and type of treatment patients received. Also no significant relation was found between chest pain and other symptoms expressed by men and women before and after treatment. Chest pain was less frequently reported by patients over 56 yrs of age in comparison to those less than 56 yrs (p < 0.05). Conclusion It seems that chest pain is the distinct symptom of achalasia which is affected by sex as well as age and does not relate to the duration of illness, LESP and the type of treatment achalasia patients receive.

Abstract
The coexistence of achalasia and gastroesophageal varices has been reported sporadically in the English medical literature. We report the case of a 60-year-old Hispanic woman with cryptogenic cirrhosis who was referred for a liver transplant evaluation and subsequently developed progressive dysphagia to both solids and liquids as well as substernal chest pain and weight loss. Endoscopy revealed the presence of grade I esophageal varices and large fundic varices, as well as retained liquid and solid food in the distal esophagus. Radiographic and manometric studies were consistent with achalasia. After botulinum toxin (Botox) injections were no longer effective a transjugular intrahepatic portosystemic shunt was performed for portal decompression before proceeding with pneumatic dilation. Optimal treatment of these 2 conditions, when they occur simultaneously, is problematic. We discuss this patient's management and our approach to this infrequent combination of diseases.

Abstract
Laparoscopic myotomy has become the standard treatment for definitive management of achalasia. This study was undertaken to assess the long-term results of the procedure. Perioperative data, including a symptom score questionnaire, were collected prospectively on all patients undergoing laparoscopic myotomy. The same questionnaire was readministered by phone to patients with follow-up greater than 3.75 years. The long-term success of myotomy was defined as a 50% or greater decrease in the dysphagia score and absence of further therapy (responders). Fifty of 95 patients (age = 57 years, 23 females) were successfully contacted. Average follow-up was 6.2 years. The overall long-term success rate was 64% (responders). Forty-two patients (84%) were able to gain or maintain their weight after the procedure. Five patients (10%) required one or more endoscopic dilations after the myotomy. The mean change in dysphagia score was higher in the responder group (7.8 +/- 1.9 vs. 1.9 +/- 2.1; P = 0.001). The two groups were similar in terms of age, gender distribution, and follow-up interval (P > .05). Dor fundoplication was performed in six patients (12%), and the outcome comparisons of these patients showed no significant differences from those patients undergoing Heller alone. Overall satisfaction was achieved in 94% of contacted patients. These results confirm that laparoscopic myotomy is an effective procedure with excellent long-term symptom resolution and overall satisfaction in patients with achalasia.

Abstract
The surgical outcome of most early gastric cancer (EGC) is usually satisfactory. Some cases show bone metastasis even though the depth of cancer invasion is confined to the mucosa. The most frequent site for recurrence of EGC is the liver. Cases of EGC with bone metastasis are reviewed to clarify the clinicopathological characteristics of EGC giving rise to bone metastasis. Possible mechanisms and risk factors underlying this rare condition are proposed. Forty-six cases of bone metastasis from EGC are reviewed from published reports and meeting proceedings in Japan. This investigation suggests that risk factors for bone metastasis from EGC include depressed-type signet-ring cell carcinoma, poorly differentiated carcinoma, and/or the likely involvement of lymph node metastasis, even though the cancer is confined to the gastric mucosa. The risk factors do not include recurrence of EGC in the liver. We speculate that the mechanism of bone metastasis from EGC is via lymphatic channels and systemic circulation. Post-operative follow-up of cases should consider the development of bone metastasis from EGC. We propose the use of elevated alkaline phosphatase levels for the detection of bone metastasis and recommend bone scintigraphy in positive cases.

Abstract
AIM: Although most patients with achalasia respond to pneumatic dilation, one-third experienced recurrence, and prolonged follow-up studies on parameters associated with various outcomes are scanty. In this retrospective study, we reported a 15-years’ experience with pneumatic dilation treatment in patients with primary achalasia, and determined whether previously described predictors of outcome remain significant after endoscopic dilation.
METHODS: Between September 1989 and September 2004, 39 consecutive patients with primary symptomatic achalasia (diagnosed by clinical presentation, esophagoscopy, barium esophagogram, and manometry) who received balloon dilation were followed up at regular intervals in person or by phone interview. Remission was assessed by a structured interview and a previous symptoms score. The median dysphagia-free duration was calculated by Kaplan-Meier analysis.
RESULTS: Symptoms were dysphagia (n = 39, 100%), regurgitation (n = 23, 58.7%), chest pain (n = 4, 10.2%), and weight loss (n = 26, 66.6%). A total of 74 dilations were performed in 39 patients; 13 patients (28%) underwent a single dilation, 17 patients (48.7%) required a second procedure within a median of 26.7 mo (range 5-97 mo), and 9 patients (23.3%) underwent a third procedure within a median of 47.8 mo (range 37-120 mo). Post-dilation lower esophageal sphincter (LES) pressure, assessed in 35 patients, has decreased from a baseline of 35.8 ± 10.4-10.0 ± 7.1 mmHg after the procedure. The median follow-up period was 9.3 years (range 0.5-15 years). The dysphagia-free duration by Kaplan-Meier analysis was 78%, 61% and 58.3% after 5, 10 and 15 years respectively.
CONCLUSION: Balloon dilation is a safe and effective treatment for primary achalasia. Post-dilation LES pressure estimation may be useful in assessing response.

Abstract
AIM: To evaluate the short-term and long-term effect of the pneumatic dilation and botulinum toxin A (BTXA) injection for the cardiac achalasia.
METHODS: From July 2000 to May 2004, 35 patients with cardiac achalasia received pneumatic dilation and BTXA injection in our hospital. The improvement of the dysphagia was observed 1 and 12 mo after the treatment.
RESULTS: Of the 35 patients, their conditions of dysphagia were significantly improved. The efficacy rates were 100% and 93.9% in the following up (1 and 12 mo, respectively). Two patients were lost to follow up while dysphagia relapsed in three patients during the following up.
CONCLUSION: The pneumatic dilation and BTXA injection for cardiac achalasia is safe, stable and effective in the treatment of cardiac achalasia.
