Abstract
Introduction: Achalasia among children often fails endoscopic management (e.g., dilation, botulinum toxin). Laparoscopic esophagocardiomyotomy (L-ECM) is a standard intervention to relieve obstruction but can induce gastroesophageal reflux (GER). Concurrent anterior fundoplication (A-fundo) has been evaluated in randomized trials among adults, demonstrating mixed results on controlling postoperative GER without exacerbating dysphagia. Furthermore, evidence for the best approach among children remains sparse. We hypothesized that, among children undergoing L-ECM without mucosal violation, routine A-fundo would not improve postoperative GER control while exacerbating dysphagia. Materials and Methods: Observational data of 47 consecutive achalasia patients ≤18 years who received L-ECM (2002-2023) at a single academic institution were collected. Patient records were culled for demographics, achalasia characteristics, and outcomes. Two L-ECM groups were identified: with or without A-fundo. Patients were screened for postoperative dysphagia (additional procedures) and GER (new antireflux medications). Univariate independence testing was conducted to identify statistically significant variables. Results: Among 47 patients undergoing L-ECM, 28 (59.6%) received concurrent A-fundo. Compared with patients undergoing L-ECM alone, patients with L-ECM/A-fundo had significantly longer hospital stays (P < .01) without statistically different rates of postoperative dysphagia (P = .81) or GER (P = .51). Five children (10.6%) experienced mucosal injury with L-ECM: 4 recognized intraoperatively received A-Fundo without subsequent leak; 1 mucosal injury was missed and did not receive A-Fundo, which subsequently leaked. Conclusion: In this largest observation of pediatric achalasia patients, A-fundo appeared clinically insignificant when determining contributors to control GER or exacerbate postoperative dysphagia. A-fundo should not be routinely adopted in children having L-ECM for achalasia without further multicenter analysis but appears beneficial in cases having inadvertent mucosal violation.

Long-term outcomes of laparoscopic Heller's myotomy with angle of His accentuation in patients of achalasia cardia. Surg Endosc 2024; 38:659-670.

Abstract
BACKGROUND Laparoscopic Heller's myotomy (LHM) is an established treatment for achalasia cardia. Anti-reflux procedures (ARP) are recommended with LHM to reduce the post-operative reflux though the optimal anti-reflux procedure is still debatable. This study reports on the long-term outcomes of LHM with Angle-of-His accentuation (AOH) in patients of achalasia cardia. METHODS One hundred thirty-six patients of achalasia cardia undergoing LHM with AOH between January 2010 to October 2021 with a minimum follow-up of one year were evaluated for symptomatic outcomes using Eckardt score (ES), DeMeester heartburn (DMH) score and achalasia disease specific quality of life (A-DsQoL) questionnaire. Upper gastrointestinal endoscopy, high resolution manometry (HRM) and timed barium esophagogram (TBE) were performed when feasible and rates of esophagitis and improvement in HRM and TBE parameters evaluated. Time dependent rates of success were calculated with respect to improvement in ES and dysphagia-, regurgitation- and heartburn-free survival using Kaplan-Meier analysis. RESULTS At a median follow-up of 65.5 months, the overall success (ES ≤ 3) was 94.1%. There was statistically significant improvement in ES, heartburn score and A-DsQoL score (p < 0.00001, p = 0.002 and p < 0.00001). Significant heartburn (score ≥ 2) was seen in 12.5% subjects with 9.5% patients reporting frequent PPI use (> 3 days per week). LA-B and above esophagitis was seen in 12.7%. HRM and TBE parameters also showed a significant improvement as compared to pre-operative values (IRP: p < 0.0001, column height: p < 0.0001, column width: p = 0.0002). Kaplan-Meier analysis showed dysphagia, regurgitation, and heartburn free survival of 75%, 96.2% and 72.3% respectively at 10 years. CONCLUSIONS LHM with AOH gives a lasting relief of symptoms in patients of achalasia cardia with heartburn rates similar to that reported in studies using Dor's or Toupet's fundoplication with LHM. Hence, LHM with AOH may be a preferred choice in patients of achalasia cardia given the simplicity of the procedure.

Abstract
BACKGROUND Laparoscopic Heller's cardiomyotomy (LHC) is the preferred treatment of achalasia. It improves dysphagia by dividing muscles of the lower oesophageal sphincter, but this intervention can result in debilitating gastro-oesophageal reflux symptoms in some patients. To prevent these reflux symptoms, most surgeons add a fundoplication to Heller's cardiomyotomy, but there is no consensus regarding this or the type of fundoplication which is best suited for the purpose. OBJECTIVES To assess how the addition of a fundoplication affects postoperative reflux and dysphagia in people undergoing LHC and compare the different types of fundoplications used in combination with LHC to determine which is better at controlling reflux without worsening the dysphagia. SEARCH METHODS We searched three databases (CENTRAL, MEDLINE and Embase) on 31 October 2021 and trial registers to identify all published and unpublished randomised controlled trials (RCTs) in any language, comparing different fundoplications used in combination with LHC to treat achalasia. We also included RCTs where LHC with a fundoplication is compared with LHC without any fundoplication. SELECTION CRITERIA We only included RCTs which recruited adult participants with achalasia undergoing LHC with minimal hiatal dissection. We excluded non-randomised studies or studies involving paediatric participants. We also excluded studies where the procedure was done by open surgery and where circumferential hiatal dissection of the oesophagus was carried out, unless it was necessary to reduce a hiatus hernia or to facilitate a Toupet or Nissen fundoplication. DATA COLLECTION AND ANALYSIS Two review authors independently identified studies to be included, assessed risk of bias using the Cochrane RoB 1 tool, and extracted the data. We calculated the risk ratio (RR) with 95% confidence interval (CI) using both fixed-effect and random-effect models with Review Manager (RevMan) software. MAIN RESULTS We included eight studies in this review, with a total of 571 participants with an average age of 45 years (range 33.5 to 50). LHC without any fundoplication was performed in 65 (11.3%) participants, 298 (52.1%) had Dor fundoplication, 81 (14.1%) had Toupet fundoplication, 72 (12.6%) had Nissen's fundoplication, and 55 (9.6%) participants had angle of His accentuation. Three studies with a total of 143 participants compared LHC + Dor to LHC without fundoplication. We found that the evidence is very uncertain as to whether the addition of a Dor fundoplication made any difference to the outcome of postoperative pathological acid reflux (RR 0.37, 95% CI 0.07 to 1.89; I2 = 56%; 2 studies, 97 participants; very low-certainty evidence) and uncertain for severe postoperative dysphagia (RR 3.00, 95% CI 0.34 to 26.33; I2 = 0%; 3 studies, 142 participants; low-certainty evidence). Three studies with 174 participants compared LHC + Dor to LHC + Toupet. The evidence suggests that there may be little to no difference in the outcomes of postoperative pathological acid reflux (RR 0.75, 95% CI 0.23 to 2.43; I2 = 60%; 3 studies, 105 participants; low-certainty evidence) and severe postoperative dysphagia (RR 0.78, 95% CI 0.19 to 3.15; I2 = 0%; 3 studies, 123 participants; low-certainty evidence) between the two interventions, but the certainty of the evidence is low. One study with 138 participants compared LHC + Dor to LHC + Nissen. Nissen fundoplication caused increased severe postoperative dysphagia (RR 0.19, 95% CI 0.04 to 0.83; 1 study, 138 participants; high-certainty evidence) when compared to Dor fundoplication. This study did not show a difference in postoperative pathological acid reflux (RR 4.72, 95% CI 0.23 to 96.59; 1 study, 138 participants; low-certainty evidence), but the certainty of evidence is low. One study with 110 participants compared LHC + Dor with LCH + angle of His accentuation, and reported that severe postoperative dysphagia was similar between the two interventions (RR 1.56, 95% CI 0.27 to 8.95; 1 study, 110 participants; moderate-certainty evidence), with moderate certainty of evidence. This study did not report on postoperative pathological acid reflux. AUTHORS' CONCLUSIONS When LHC was performed with minimal hiatal dissection, we were very uncertain whether the addition of a Dor fundoplication made a difference in controlling postoperative reflux, and we were uncertain if it increased the risk of severe postoperative dysphagia. There may be little to no difference in the outcomes of postoperative pathological acid reflux or severe dysphagia between Dor and Toupet fundoplications when used in combination with LHC, but the certainty of the evidence is low. Nissen (total) fundoplication used in combination with LHC for achalasia increased the risk of severe postoperative dysphagia. The angle of His accentuation and Dor fundoplication had a similar effect on severe postoperative dysphagia when combined with LHC, but their effect on postoperative pathological acid reflux was not reported.

Abstract
Background and Objectives: The primary aim of this study is to assess the necessity of fundoplication for reflux in patients undergoing Heller myotomy for achalasia. The secondary aim is to assess the safety of the robotic approach to Heller myotomy. Methods: This is a single institution, retrospective analysis of 61 patients who underwent robotic Heller myotomy with or without fundoplication over a 4-year period (January 1, 2015 – December 31, 2019). Symptoms were evaluated using pre-operative and postoperative Eckardt scores at < 2 weeks (short-term) and 4 – 55 months (long-term) postoperatively. Incidence of gastroesophageal reflux and use of antacids postoperatively were assessed. Long-term patient satisfaction and quality of life (QOL) were assessed with a phone survey. Finally, the perioperative safety profile of robotic Heller myotomy was evaluated. Results: The long-term average Eckardt score in patients undergoing Heller myotomy without fundoplication was notably lower than in patients with a fundoplication (0.72 vs 2.44). Gastroesophageal reflux rates were lower in patient without a fundoplication (16.0% vs 33.3%). Additionally, dysphagia rates were lower in patients without a fundoplication (32.0% vs 44.4%). Only 34.8% (8/25) of patients without fundoplication continued use of antacids in the long-term. There were no mortalities and a 4.2% complication rate with two delayed leaks. Conclusion: Robotic Heller myotomy without fundoplication is safe and effective for achalasia. The rate of reflux symptoms and overall Eckardt scores were low postoperatively. Great patient satisfaction and QOL were observed in the long term. Our results suggest that fundoplication is unnecessary when performing Heller myotomy.

Abstract
Achalasia is a progressive neurodegenerative disorder characterized by failure of relaxation of the lower esophageal sphincter (LES) and altered motility of the esophagus. The traditional, highly effective, surgical approach to relieve obstruction at the LES includes cardiomyotomy. Fundoplication is added to decrease risk of postoperative reflux. Per oral endoscopic myotomy is a new endoscopic procedure that allows division of the LES via transoral route. It has several advantages including less invasiveness, cosmesis, and tailored approach to the length on the myotomy. However, it is associated with increased rate of post-procedural reflux. Various endoscopic interventions are used to address this problem.

Abstract
BACKGROUND To evaluate the clinical outcomes and satisfaction of patients following laparoscopic Heller myotomy for achalasia cardia in four tertiary centers. METHODS Fifty-five patients with achalasia cardia who underwent laparoscopic Heller myotomy between 2010 and 2019 were enrolled. The adverse events and clinical outcomes were analyzed. Overall patient satisfaction was also reviewed. RESULTS The mean operative time was 144.1 ± 38.33 min with no conversions to open surgery in this series. Intraoperative adverse events occurred in 7 (12.7%) patients including oesophageal mucosal perforation (n = 4), superficial liver injury (n = 1), minor bleeding from gastro-oesophageal fat pad (n = 1) & aspiration during induction requiring bronchoscopy (n = 1). Mean time to normal diet intake was 3.2 ± 2.20 days. Mean postoperative stay was 4.9 ± 4.30 days and majority of patients (n = 46; 83.6%) returned to normal daily activities within 2 weeks after surgery. The mean follow-up duration was 18.8 ± 13.56 months. Overall, clinical success (Eckardt ≤ 3) was achieved in all 55 (100%) patients, with significant improvements observed in all elements of the Eckardt score. Thirty-seven (67.3%) patients had complete resolution of dysphagia while the remaining 18 (32.7%) patients had some occasional dysphagia that was tolerable and did not require re-intervention. Nevertheless, all patients reported either very satisfied or satisfied and would recommend the procedure to another person. CONCLUSIONS Laparoscopic Heller myotomy and anterior Dor is both safe and effective as a definitive treatment for treating achalasia cardia. It does have a low rate of oesophageal perforation but overall has a high degree of patient satisfaction with minimal complications.

Abstract
BACKGROUND There is no consensus regarding the type of anti-reflux procedure to be used as an adjunct to laparoscopic Heller cardiomyotomy (LHCM). The aim of this study was to compare Angle of His accentuation (AOH) with Dor Fundoplication (Dor) as an adjunct to LHCM. METHODS A total of 110 patients with achalasia cardia presenting for LHCM from March 2010 to July 2015 were randomized to Dor and AOH. Symptom severity, achalasia-specific quality of life (ASQOL), new onset heartburn, and patient satisfaction were assessed using standardized scores preoperatively, at 3, 6 months, and then yearly. The primary outcome was relief of esophageal symptoms while secondary outcomes were new onset heartburn and ASQOL. RESULTS Both groups were comparable with respect to the baseline demographic characteristics. There was no conversion to open and no mortality in either group. Median operative time was 128 min in AOH and 144 min in Dor group (p < 0.01). Mean follow-up was 36 months and was available in 98% patients. There was significant improvement in esophageal symptoms in both groups with no statistically significant difference between the two groups (p > 0.05). There was no difference in cumulative symptom scores between the two groups over the period of follow-up. New onset heartburn was seen in 11% in AOH and 9% in Dor group. Mean ASQOL score improved in both groups with no difference between the two groups (p = 0.83). Patient satisfaction was similar in both groups. CONCLUSION AOH is similar to Dor as an adjunct to LHCM in safety and efficacy and can be performed in shorter time. CLINICAL REGISTRATION NUMBER CTRI: REF/2014/06/007146.

Abstract
Achalasia is a relatively rare primary motor esophageal disorder, characterized by absence of relaxations of the lower esophageal sphincter and of peristalsis along the esophageal body. As a result, patients typically present with dysphagia, regurgitation and occasionally chest pain, pulmonary complication and malnutrition. New diagnostic methodologies and therapeutic techniques have been recently added to the armamentarium for treating achalasia. With the aim to offer clinicians and patients an up-to-date framework for making informed decisions on the management of this disease, the International Society for Diseases of the Esophagus Guidelines proposed and endorsed the Esophageal Achalasia Guidelines (I-GOAL). The guidelines were prepared according the Appraisal of Guidelines for Research and Evaluation (AGREE-REX) tool, accredited for guideline production by NICE UK. A systematic literature search was performed and the quality of evidence and the strength of recommendations were graded according to the Grading of Recommendations Assessment, Development and Evaluation (GRADE). Given the relative rarity of this disease and the paucity of high-level evidence in the literature, this process was integrated with a three-step process of anonymous voting on each statement (DELPHI). Only statements with an approval rate >80% were accepted in the guidelines. Fifty-one experts from 11 countries and 3 representatives from patient support associations participated to the preparations of the guidelines. These guidelines deal specifically with the following achalasia issues: Diagnostic workup, Definition of the disease, Severity of presentation, Medical treatment, Botulinum Toxin injection, Pneumatic dilatation, POEM, Other endoscopic treatments, Laparoscopic myotomy, Definition of recurrence, Follow up and risk of cancer, Management of end stage achalasia, Treatment options for failure, Achalasia in children, Achalasia secondary to Chagas' disease.

Abstract
Heller myotomy (HM) is widely recognized as the most effective treatment of achalasia. Although effective in improving dysphagia symptoms, HM is associated with reflux. Over a five-year period, 63 laparoscopic HM were performed. Patients underwent myotomy alone or HM plus reconstitution of the angle of His without any fundoplication, anterior, or posterior partial fundoplication. Two postoperative outcomes were examined: dysphagia and reflux. Twenty-two patients received no fundoplication (34.9%). Forty-one (65.1%) antireflux procedures were performed, including 21 reconstitutions of the angle of His (33.3%), nine (14.3%) anterior fundoplications, and 11 (17.5%) posterior fundoplications. All patients demonstrated preoperative dysphagia. Postoperative dysphagia was present in 23 of 63 (36.5%). Of these, 13 (56.5%) patients had an antireflux procedure, whereas 28 of 40 who had an antireflux procedure (70%) had no postoperative dysphagia (P = 0.28). Thirty-nine of 62 (62.9%) had symptomatic esophageal reflux preoperatively, and postoperative reflux was reported in 22 of 63 (34.9%). Reflux was present in 72.7 per cent of patients who had an antireflux procedure versus 61 per cent of those without the addition of an antireflux procedure (P = 0.415). However, HM independently improved reflux status regardless of whether an antireflux procedure was performed using the exact McNemar's test (P = 0.0014). Although the performance of an antireflux procedure did not appear to alter the reflux status after HM for achalasia, neither was it associated with postoperative dysphagia. More importantly, HM was independently associated with an improvement of reflux symptoms regardless of the type of antireflux procedure performed or whether one was used or not.

Abstract
AIMS AND OBJECTIVES Laparoscopic Heller myotomy (LHM) is the preferred surgical method for treating achalasia. However, peroral endoscopic myotomy (POEM) is providing good short-term results. The objective of this systematic review and meta-analysis was to compare the safety and efficacy of LHM and POEM. MATERIALS AND METHODS A search of PubMed, Cochrane database, Medline, Embase, Science Citation Index, and current contents for English-language articles comparing LHM and POEM between 2007 and 2016 was performed. Variables analyzed included prior endoscopic treatment, prior medical treatment, prior Heller myotomy, operative time, overall complications rate, postoperative gastroesophageal reflux disease (GERD), length of hospital stay, postoperative pain score, and long-term GERD. RESULTS Seven trials consisting of 483 (LHM=250, POEM=233) patients were analyzed. Preoperative variables, for example, prior endoscopic treatment [odds ratio (OR), 1.32; 95% confidence interval (CI), 0.23-4.61; P=0.96], prior medical treatment [weighted mean difference (WMD), 1.22; 95% CI, 0.52-2.88; P=0.65], and prior Heller myotomy (WMD, 0.47; 95% CI, 0.13-1.67; P=0.25) were comparable. Operative time was 26.28 minutes, nonsignificantly longer for LHM (WMD, 26.28; 95% CI, -11.20 to 63.70; P=0.17). There was a comparable overall complication rate (OR, 1.25; 95% CI, 0.56-2.77; P=0.59), postoperative GERD rate (OR, 1.27; 95% CI, 0.70-2.30; P=0.44), length of hospital stay (WMD, 0.30; 95% CI, -0.24 to 0.85; P=0.28), postoperative pain score (WMD, -0.26; 95% CI, -1.58 to 1.06; P=0.70), and long-term GERD (WMD, 1.06; 95% CI, 0.27-4.1; P=0.08) for both procedures. There was a significantly higher short-term clinical treatment failure rate for LHM (OR, 9.82; 95% CI, 2.06-46.80; P<0.01). CONCLUSIONS POEM compares favorably to LHM for achalasia treatment in short-term perioperative outcomes. However, there was a significantly higher clinical treatment failure rate for LHM on short-term postoperative follow-up. Presently long-term postoperative follow-up data for POEM beyond 1 year are unavailable and eagerly awaited.

Abstract
Introduction Two types of partial wrap are commonly performed in achalasia patients after Heller myotomy: the posterior 270° fundoplication (Toupet) and the anterior 180° fundoplication (Dor). The optimal type of fundoplication (posterior vs. anterior) is still debated. Aim To compare the long-term rates of dysphagia, reflux symptoms and patient satisfaction with current postoperative condition between two fundoplication groups in achalasia treatment. Material and methods Our retrospective study included 97 consecutive patients with achalasia: 37 patients underwent laparoscopic posterior Toupet (270°) fundoplication followed by Heller myotomy (group I); 60 patients underwent laparoscopic anterior partial Dor fundoplication followed by Heller myotomy (group II). Long-term follow-up results included evaluation of dysphagia symptoms, intensity of heartburn and patient satisfaction with current condition. Results Patients in these two groups did not differ according to age, weight, height, postoperative stay or follow-up period. Laparoscopic myotomy with posterior Toupet fundoplication was effective in 89% of patients, while laparoscopic myotomy with anterior Dor was effective in 93% of patients (p > 0.05). 11% of patients after posterior Toupet fundoplication had clinically significant heartburn vs. 35% of patients after anterior Dor fundoplication (p < 0.05). Overall patient satisfaction with current condition was 88%, with no significant difference between the groups. Conclusions According to our study results, the two laparoscopic techniques were similarly effective in reducing achalasia symptoms, but postoperative clinical manifestation of heartburn is significantly more frequent after anterior Dor fundoplication (35% vs. 11%). The majority of patients (88%) were satisfied with operation outcomes.

Abstract
INTRODUCTION Achalasia is a rare disorder in children who are commonly treated by laparoscopic Heller's myotomy (LHM). However, there are no large studies evaluating the results of LHM in the pediatric population, and the need of a concomitant fundoplication remains unclear. The aim of the study is to appraise the results of LHM based on a systematic literature review. MATERIALS AND METHODS MEDLINE search of the English literature was performed for "achalasia," "children," "laparoscopy," "Heller," "myotomy," and "cardiomyotomy." Frequency of postoperative symptoms was grouped to calculate the percentage of patients with symptoms improvement. Incidence of postoperative gastro-esophageal reflux (GER) and dysphagia between patients with and without fundoplication at the time of LHM was compared by Fisher's Exact Test. P < .05 was regarded as significant. RESULTS Twenty-one studies were analyzed (331 children, 1-19 years). All studies were retrospective case-series reviews. Intraoperative complications occurred in 33 patients (10%), with esophageal perforations in 31 (9%), and conversion to open procedure in 9 (2.7%). Fundoplication was performed in 271 (82%): Dor (n = 205, 76%), Toupet (n = 49, 18%), Thal (n = 13, 4.5%), and Nissen (n = 4, 1.5%). Incidence of postoperative GER and dysphagia was similar between children with and without fundoplication (P = 1). Forty-nine (15%) required re-intervention: pneumatic dilatations (n = 30, 9%), redo-surgery (n = 23, 7%), botox injection (n = 1, 0.3%), and medical therapy (n = 5, 1.5%). DISCUSSION LHM for achalasia is effective in 85% of children. Revision surgery is required in 7%. There is no difference in incidence of GER and dysphagia between patients with and without fundoplication. Routine use of an additional fundoplication might not be justified.

Greater curvature myotomy is a safe and effective modified technique in per-oral endoscopic myotomy (with videos). Gastrointest Endosc 2016; 81:1370-7.

Abstract
BACKGROUND Per-oral endoscopic myotomy (POEM) for achalasia with esophagocardiomyotomy in the lesser curvature (LC myotomy) is now established and accepted widely. However, in some cases LC myotomy is precluded by previous procedures, such as Heller myotomy, or by other anatomic considerations that obscure the normal dissection planes. It may also be difficult to identify the esophagogastric junction (EGJ), which can result in an incomplete gastric myotomy and poor rates of symptom relief. On the other hand, the angle of His is always located in the greater curvature of the stomach and serves as a consistent, definite landmark of the gastric side. OBJECTIVE To evaluate esophagocardiomyotomy in the greater curvature (GC myotomy) as an alternative POEM technique in cases where a prior LC myotomy or supervening anatomic constraints make identification of the EGJ technically challenging. DESIGN Prospective. SETTING Single-center study. PATIENTS Twenty-one achalasia patients who received POEM with GC myotomy. INTERVENTIONS POEM. MAIN OUTCOME MEASUREMENTS Efficacy and safety of GC myotomy measured in terms of reduction in lower esophageal sphincter (LES) pressures, improvement in Eckardt scores, and development of intraoperative or postoperative adverse events. RESULTS Identification of the EGJ was achieved in all cases, resulting in a mean gastric myotomy length of 2.6±1.1 cm. Mean LES pressure and Eckardt symptom scores decreased significantly (21.2±7.3 vs 10.5±2.7 mm Hg, 5 [2-8] vs 1 [0-5], respectively) (P<.01). Endoscopic evidence of gastroesophageal reflux was identified in 52% of patients (11/21) postmyotomy; however, only 9.5% (2/11) were symptomatic, and these patients were successfully controlled with proton pump inhibitors. No severe adverse events were encountered. LIMITATIONS Single center. CONCLUSIONS GC myotomy is a promising, safe modification of the POEM technique and may be especially useful in cases of redo POEM, POEM post-Heller myotomy, or when the EGJ is difficult to recognize because of supervening anatomic constraints.

Abstract
Laparoscopic Heller's cardiomyotomy is a well-established technique in the treatment of achalasia. However, the addition of a routine fundoplication as part of this procedure remains controversial. A best evidence topic in upper gastrointestinal surgery was written according to a structured protocol. The question addressed whether the addition of a fundoplication improved clinical outcomes. Two hundred and seven papers were found using the reported search and of these, 8 papers were identified using a pre-determined criteria as representing the best answer to this clinical question. There were 2 meta-analyses, 3 randomised controlled trials and 3 prospective series. The author, journal, date and country of publication, patient group, study type, relevant outcomes, results, and study weaknesses of these papers are tabulated. Review of the data shows that the rates of gastro-oesophageal reflux both on pH monitoring and symptom reporting are all reduced when an anti-reflux procedure is added to a Heller's cardiomyotomy. In terms of the choice of the anti-reflux procedure, comparison between the Dor anterior and Toupet posterior fundoplications do not show any obvious clinical differences, however dysphagia appears to be lower in those undergoing partial fundoplication as compared to a Nissen fundoplication.

Abstract
BACKGROUND/AIM We report the results of a short- and long-segment cardiomyotomy for relief of the symptoms of achalasia. PATIENTS AND METHODS From 1997 to 2009, 41 patients (22 men, 19 women) with achalasia underwent cardiomyotomy. Patients were divided into 2 groups [short-segment group (SSG) and long-segment group (LSG)]. SSG include 22 patients with laparotomy and 8-cm short-segment myotomy and Dor fundoplication. LSG includes 19 patients with thoracotomy and 12-cm long-segment myotomy and Belsey partial fundoplication. results: Median follow up was 48 months (range: 12-70 months). Postoperative dysphagia improved in 20 patients in SSG and in 17 patients in LSG (P < 0.001). Slow emptying sensation improved in 19 patients in SSG and in 16 patients in LSG postoperatively (P < 0.001). Heartburn was present in 2 patients in SSG and 3 patients in LSG postoperatively (P = 0.179). Radiologically, barium stasis decreased significantly from 88% to 25% in SSG and from 85% to 30% in LSG. The lower esophageal sphincter (LES) gradient decreased from 32 to 10 mmHg in SSG and from 34 to 14 mmHg in LSG (P < 0.001). CONCLUSIONS Short-segment cardiomyotomy reduces the LES gradient and relieves obstructive symptoms.

Abstract
Achalasia is a rare motor disorder of the esophagus, characterized by the absence of peristalsis and impaired swallow-induced relaxation. In the past decade, evidence has been accumulated suggesting that achalasia may be an immune-mediated inflammatory disorder. With the advent of minimally invasive surgery, laparoscopic Heller myotomy (LHM) has slowly shifted the treatment of achalasia toward the greater use of surgical therapy. The goal of both surgical and nonsurgical treatment is to eliminate the outflow obstruction afforded by a nonrelaxing sphincter, relieving dysphagia and maintaining a barrier against gastroesophageal reflux (GER). Endoscopic botulinum toxin injection (EBTI) is safe, easy to perform, inexpensive, and effective in aged patients, and it is especially effective when the lower esophageal pressure is hypertonic. This therapeutic option is reserved for patients too ill to undergo any surgical procedure. Pneumatic dilation (PD) has been shown to be an effective and inexpensive treatment with few adverse effects. The long-term success rate of PD seems to drop progressively over time. Heller myotomy (HM) has shown the best clinical efficacy in achalasia as a first-line treatment. Multiple endoscopic treatments are associated with poorer outcomes after HM. EBTI also makes LHM more difficult and results in a worse surgical outcome. The inferior symptomatic outcomes after thoracoscopic HM may be caused by the difficulty in extending an adequate myotomy onto the stomach from the chest and the inability to create a fundoplication. LHM with Dor's fundoplication (LHM + Dor) is effective and is safer procedure for avoiding GER, dysphagia, mucosal perforation, and a pseudodiverticulum. LHM + Dor is also effective in the presence of sigmoid achalasia, but the clinical result is not as good as nonsigmoid achalasia. A few patients need esophagectomy for surgical failure of HM. However, considering the risk of esophagectomy, LHM + Dor is the first treatment option for patients with achalasia regardless of the degree of esophageal dilatation. This procedure is therefore considered to be an effective and safe treatment for patients of any age or with any condition.

Abstract
INTRODUCTION Heller myotomy using the laparoscopic approach is the best treatment that we can offer to patients with achalasia. On not acting on the cause of the disease, we can only alleviate the persistence of the symptoms, but not make them disappear. OBJECTIVE To analyse the results of our group in the treatment of achalasia by laparoscopy. MATERIAL AND METHODS The pre- and post-operative results are analysed of a series of 20 patients intervened prospectively by laparoscopy of achalasia during a period from May 2003 to April 2010. For this we used a modification of the grading scale of pre- and post-operative symptoms described by Velanovich for GER (a scale from 0-5). Data on the complications and the hospital stay were also collected. RESULTS A wide Heller myotomy was performed using a Dor type antireflux mechanism. There were no oesophageal perforations or complications during the surgery. Two (10%) patients had postoperative complications. The mean hospital stay was 3.11 ± 2.13 days. After a mean follow up of 55.8 ± 14.1 months, the symptoms studied had significantly decreased after the surgery. Only 3 (15%) patients had clinical symptoms of GER after surgery. Nineteen patients (95%) said they were satisfied with the operation. CONCLUSIONS The laparoscopic treatment of achalasia is a safe technique, reproducible and effective technique, which achieves very satisfactory control of the achalasia symptoms with a minimum of morbidity.

OBJECTIVE Quality of outcome of the Heller-Dor operation is sometimes different between studies, likely because of technical reasons. We analyze the details of myotomy and fundoplication in relation to the results achieved over a 30-year single center's experience. METHODS From 1979-2008, a long esophagogastric myotomy and a partial anterior fundoplication to protect the surface of the myotomy was routinely performed with intraoperative manometry in 202 patients (97 men; median age, 55.5 years; interquartile range, 43.7-71 years) through a laparotomy and in 60 patients (24 men; median age, 46 years; interquartile range, 36.2-63 years) through a laparoscopy. The follow-up consisted of periodical interview, endoscopy, and barium swallow, and a semiquantitative scale was used to grade results. RESULTS Mortality was 1 of 202 in the laparotomy group and 0 of 60 in the laparoscopy group. Median follow-up was 96 months (interquartile range, 48-190.5 months) in the laparotomy group and 48 months (interquartile range, 27-69.5 months) in the laparoscopy group. At intraoperative manometry, complete abolition of the high-pressure zone was obtained in 100%. The Dor-related high-pressure zone length and mean pressure were 4.5 ± 0.4 cm and 13.3 ± 2.2 mm Hg in the laparotomy group and 4.5 ± 0.5 cm and 13.2 ± 2.2 mm Hg in the laparoscopy group (P = .75). In the laparotomy group poor results (19/201 [9.5%]) were secondary to esophagitis in 15 (7.5%) of 201 patients (in 2 patients after 184 and 252 months, respectively) and to recurrent dysphagia in 4 (2%) of 201 patients, all with end-stage sigmoid achalasia. In the laparoscopy group 2 (3.3%) of 60 had esophagitis. CONCLUSIONS A long esophagogastric myotomy protected by means of Dor fundoplication cures or substantially reduces dysphagia in the great majority of patients affected by esophageal achalasia and effectively controls postoperative esophagitis. Intraoperative manometry is likely the key factor for achieving the reported results.

Abstract
INTRODUCTION It is speculated that postoperative pathologic gastroesophageal reflux after Heller's myotomy can be diminished if the lateral and posterior phrenoesophageal attachments are left intact. The aim of this study was to evaluate the effectiveness of limited hiatal dissection in patients operated due to achalasia. METHODS Prospective, randomized, 3 years follow-up of 84 patients operated due to achalasia. In 26 patients, Heller-Dor with complete hiatal dissection was done (G1), limited hiatal dissection combined with myotomy and Dor's procedure was performed in 36 patients (G2), and with Heller's myotomy alone in 22 (G3). Stationary manometry and 24 h pH study were performed in regular postoperative intervals. RESULTS Postoperatively, higher median values of lower esophageal sphincter resting pressures were marked in G2 and G3, while patients in G1 were presented with higher median values of pH acid score (p < 0.001). Abnormal DeMeester score 3 years after surgery was present in 23.1% of patients in G1 and 8.5% and 9.1% in G2 and G3 accordingly. There was no statistical difference between the groups concerning postoperative dysphagia recurrence. CONCLUSION Indicating further long-term studies, 3 years after the operation limited hiatal dissection compared to complete obtains better reflux control in achalasia patients, regardless of Dor's fundoplication.

Abstract
INTRODUCTION Heller myotomy leads to good-excellent long-term results in 90% of patients with achalasia and thereby has evolved to the "first-line" therapy. Failure of surgical treatment, however, remains an urgent problem which has been discussed controversially recently. MATERIALS AND METHODS A systematic review of the literature was performed to analyze the long-term results of failures after Heller's operation with emphasis on treatment by remedial myotomy. DISCUSSION Other reinterventions and their causes after failure of surgical treatment in patients with achalasia are discussed.

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
Pharmacological therapy, botulinum toxin injection, pneumatic dilatation, and surgical myotomy are the primary therapeutic modalities for achalasia, for which laparoscopic myotomy is recommended as state-of-the-art therapy. However, its efficacy and safety remain unclear compared with other approaches in the treatment of achalasia. We searched electronic databases (MEDLINE, EMBASE, Cochrane Central Registry of Controlled Trials, LILACS-Latin American, Caribbean health science literature, and Science Citation Index Expanded) for randomized controlled trials to evaluate which therapeutic measures are temporary and reversible and which measures are definitive and effective by pooling data including remission rate, relapse rate, complications, and adverse effects. Seventeen studies with 761 patients met our inclusion criteria. There was better remission rate in pneumatic dilation than in botulinum toxin injection for initial intervention [relative risk (RR) 2.20, 95% confidence interval (CI) 1.51-3.20], Pneumatic dilation had lower relapse rate than did botulinum toxin injection (RR 0.12, 95% CI 0.04-0.32). Compared with pneumatic dilation, laparoscopic myotomy further increased remission rate (RR 1.48, 95% CI 1.48-1.87), and reduced clinical relapse rate (RR 0.14, 95% CI 0.04-0.58), and there was no difference in complication rate (RR 1.48, 95% CI 0.37-5.99). Based on limited randomized and controlled trials, laparoscopic myotomy is the preferred method for patients with achalasia. Future trials should investigate whether laparoscopic myotomy combined with different modalities of fundoplication is superior to isolated laparoscopic myotomy.

Abstract
INTRODUCTION Achalasia is a primary oesophageal motility disorder resulting from damage to the ganglion cells of the myenteric plexus. Impaired relaxation of the lower oesophageal sphincter and aperistalsis causes its cardinal symptoms of dysphagia, chest pain and reflux-type symptoms. Management is somewhat controversial, with options including systemic and local pharmacotherapy, dilatation and oesophagomyotomy. We review the presentation, investigation and management of oesophageal achalasia and make an argument for primary surgical management. METHODS We performed a Medline search of the term 'achalasia', limiting the search to clinical trials and meta-analyses. We then selected articles based on their abstracts using four main criteria: previously unreported findings, previously unreported techniques, size of patient cohort and journal impact factor. References in selected articles were manually searched for other relevant articles. FINDINGS Achalasia has been managed using a variety of techniques including systemic and local pharmacotherapy, forced dilatation and oesophagomyotomy. Success rates vary widely between techniques. Mechanical disruption ofthe lower oesophageal sphincter is most successful. DISCUSSION In achalasia, mechanical disruption of the lower oesophageal sphincter using forced dilatation or surgical myotomy offers the only realistic prospect of long-term symptom relief. Recent evidence suggests that previous medical treatment or dilatation makes oesophagomyotomy more difficult and increases the risk of complications. As the morbidity associated with surgery continues to decrease with improvements in minimal access techniques, the argument for primary management of achalasia with oesophagomyotomy becomes more compelling.

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
INTRODUCTION Laparoscopic Heller myotomy is a first-line treatment for achalasia. To improve outcomes after myotomy and to determine if poor early results predict later outcomes, emergency department (ED) visits and readmissions within 60 days following laparoscopic Heller myotomy were studied. MATERIALS AND METHODS Since 1992, 352 patients have undergone laparoscopic Heller myotomy and are followed through a prospectively maintained registry. Causes of ED visits and readmissions within 60 days after myotomy were determined. Patients scored their symptoms of achalasia before myotomy and at last follow-up; scores were compared to determine if the reasons leading to ED visits and/or readmissions impacted long-term outcome after myotomy. RESULTS Fourteen (4%) patients had ED visits, and 18 (5%) patients had readmissions within 60 days following myotomy. Sixty-four percent of ED visits were for dysphagia/vomiting and 36% were for abdominal/chest pain, while 37% of readmissions were for dysphagia/vomiting. Pneumonia was complicated by empyema in four patients, all without leaks; two patients expired. Despite ED visits/readmissions, achalasia symptom (e.g., dysphagia, regurgitation, choking, heartburn, and chest pain) frequency and severity scores improved after myotomy (p < 0.05 for all). CONCLUSIONS ED visits and readmissions are infrequent following laparoscopic Heller myotomy. ED visits were generally due to complaints related to achalasia or edema after myotomy, while readmissions were generally related to complications of operative intervention or chronic ill health. Despite ED visits or readmissions early after myotomy, symptoms of achalasia are well palliated by myotomy long-term.

Abstract
The aim of surgical treatment in achalasia cardia is symptom relief. Most studies have evaluated the results of laparoscopic cardiomyotomy with an antireflux procedure. However, data on the effectiveness of laparoscopic cardiomyotomy without an antireflux procedure is sparse. We describe our experience of laparoscopic cardiomyotomy without antireflux procedure in 40 consecutive patients with respect to symptom relief and complications. There was no mortality and 1 conversion. Preoperatively dysphagia, regurgitation, and heartburn were present in 40, 39, and 11 patients. At a mean follow-up of 26 months, there was a significant improvement in symptom scores. Two patients (5%) had persistent postoperative dysphagia. One improved on conservative therapy, whereas other was treated with relaparoscopic cardiomyotomy. Three patients (7.5%) developed heartburn in the postoperative period, which was well controlled with proton pump inhibitors. Laparoscopic cardiomyotomy without antireflux procedure results in excellent relief of dysphagia without producing significant symptomatic reflux in the follow-up.

Abstract
Concerns for gastroesophageal reflux after laparoscopic Heller myotomy for achalasia justify considerations of concomitant anterior fundoplication. This study was undertaken to determine if concomitant anterior fundoplication reduces symptoms of reflux after myotomy without promoting dysphagia. From 1992 to 2004, 182 patients underwent laparoscopic Heller myotomy without fundoplication. After a prospective randomized trial justified its concomitant application, anterior fundoplication was undertaken with laparoscopic Heller myotomy in 171 patients from 2004 to 2007. All patients have been prospectively followed. Pre and postoperatively, patients scored the frequency and severity of symptoms of achalasia (including dysphagia, choking, vomiting, regurgitation, chest pain, and heartburn) using a Likert Scale (0 = never/not bothersome to 10 = always/very bothersome). Before myotomy, symptoms of achalasia were frequent and severe for all patients. After myotomy, the frequency and severity of all symptoms of achalasia significantly decreased for all patients ( P < 0.001, Wilcoxon matched pairs test). Notably, relative to patients undergoing laparoscopic Heller myotomy alone, concomitant anterior fundoplication led to significantly less frequent and severe heartburn after myotomy ( P < 0.05, Mann-Whitney Test) and to less frequent and severe dysphagia and choking ( P < 0.05, Mann-Whitney Test). Laparoscopic Heller myotomy reduces the frequency and severity of symptoms of achalasia. Concomitant anterior fundoplication decreases the frequency and severity of heartburn and dysphagia after laparoscopic Heller myotomy. Concomitant anterior fundoplication promotes salutary relief in the frequency and severity of symptoms after myotomy and is warranted.

Abstract
Achalasia is a rare primary motility disorder of the esophagus with a United States prevalence of less than 0.001%. Laparoscopic modified Heller myotomy has become the standard of care for palliation of this incurable but benign disease. The role of a fundoplication with the myotomy continues to be controversial. This report summarizes the current laparoscopic management of achalasia with a review of the medical literature on the outcome of combining a fundoplication with a laparoscopic myotomy. The optimal length of myotomy as suggested in the literature is also summarized. To complete the goal, peer-reviewed publications were identified in PubMed by search terms achalasia, myotomy, fundoplication, Nissen, Dor, and Toupet.

Abstract
BACKGROUND Heller's myotomy for esophageal achalasia is associated with less esophageal acid gastroesophageal reflux when combined a Dor's fundoplication. The Aim of the study was to assess the incidence of postoperative esophageal acid exposure after laparoscopic Heller's myotomy and Dor's fundoplication (HM-DF). METHODS Seventy six patients (37 males) with esophageal achalasia were prospectively followed-up by clinical interview and laboratory tests before and after laparoscopic HM-DF. A symptom score was used for clinical assessment. Laboratory assessment included esophageal standard manometry, esophagogram and esophageal pH 24-hour monitoring before and 1- and 5-years after surgery. RESULTS Symptom score improved at 1-year after surgery (P < 0.001). Heartburn was only reported by 5 patients, dysphagia or/and regurgitation by 28 and substernal pain by 12. 91% of patients had satisfactory functional results. Pathological esophageal exposure to acid was seen in 21% of the cases. Pathological acid events showed the features of pseudoreflux in 66%t and those of true GER in 34%. Pathologically increased esophageal exposure to acid was more commonly detected in patients with a pseudodiverticulum (P = 0.001) and was related to the diameter of distal esophagus and symptom score (P < 0.001). There was no reduction in esophageal acid exposure after treatment with proton pump inhibitors in 16 patients. Neither the symptom score nor esophageal acid exposure at esophageal pH monitoring changed significantly at the 5-year follow-up in 35 patients. Esophageal configuration remained unchanged. CONCLUSIONS Increased esophageal exposure to acid after laparoscopic HM-DF for esophageal achalasia i) is detected in 21% of patients, and is rather the result of food stagnation than of true GER, ii) is more commonly seen in cases with pseudodiverticulum, iii) is related to the diameter of distal esophagus, iv) does not respond to antisecretory treatment and v) does not deteriorate by time.

Pathological esophageal exposure to acid was seen in 21% of the cases. Pathological acid events showed the features of pseudoreflux in 66%t and those of true GER in 34%. Pathologically increased esophageal exposure to acid was more commonly detected in patients with a pseudodiverticulum (P = 0.001) and was related to the diameter of distal esophagus and symptom score (P < 0.001). There was no reduction in esophageal acid exposure after treatment with proton pump inhibitors in 16 patients. Neither the symptom score nor esophageal acid exposure at esophageal pH monitoring changed significantly at the 5-year follow-up in 35 patients. Esophageal configuration remained unchanged. CONCLUSIONS Increased esophageal exposure to acid after laparoscopic HM-DF for esophageal achalasia i) is detected in 21% of patients, and is rather the result of food stagnation than of true GER, ii) is more commonly seen in cases with pseudodiverticulum, iii) is related to the diameter of distal esophagus, iv) does not respond to antisecretory treatment and v) does not deteriorate by time.

[PMID: 17943360 DOI: 10.1007/s00464-007-9600-6] [Citation(s) in RCA: 26] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2007] [Revised: 07/31/2007] [Accepted: 08/13/2007] [Indexed: 12/12/2022]
Abstract
BACKGROUND Heller myotomy (HM) combined with an anti-reflux procedure has been shown to be effective for the treatment of achalasia, as postoperative gastro-esophageal reflux (GER) is observed in about 10% of the cases. Laparoscopy has brought an undeniable benefit in providing excellent visualisation of the gastro-esophageal junction (GEJ) without lateral and posterior dissection. Respecting the anatomical fixation of the GEJ seems to permit the performing of HM without an anti-reflux procedure, the need for which is therefore debatable. The purpose of this study was to analyse the results of this controversial procedure. METHODS A monocentric prospective study was carried out on 106 patients who underwent HM without an anti-reflux procedure. The postoperative assessment consisted of a manometry and a 24-hour pH study two months after surgery, and a yearly clinical examination for a minimum of five years. The data capture was done using a statistical analysis. RESULTS There was no mortality, one conversion to an open procedure, and four mucosal perforations. Postoperative morbidity was 2%. The average follow-up period was 55 months (range, 2 to 166), with 10 patients lost to follow-up. Good functional results were observed in 91.4% of patients at one year, and 78.6% at five years. Two months after surgery, a 9.4% prevalence of GER was detected in the pH study, and the lower esophageal sphincter pressure had significantly decreased. After a long term follow-up we observed an 11.3% global rate of GER. No repeat surgery was necessary to control postoperative GER. CONCLUSIONS Laparoscopic HM without anti-reflux procedure gives good functional results provided the anatomical fixation of the GOJ is respected.

Abstract
Esophageal motor and sensory disorders are relatively rare conditions in the general population and afflicted patients are often initially misdiagnosed as having gastroesophageal reflux disease. Tests for these disorders have imperfect gold standards and are adjuncts to sound diagnostic reasoning. Treatments are palliative and have not been rigorously evaluated for some disorders. Symptoms and complications from disease progression and relapse are common, so that patients need continued follow-up.

Abstract
BACKGROUND The two main treatment options for esophageal achalasia are laparoscopic distal esophageal myotomy (LM) and pneumatic dilatation (PD). Our objective was to compare the costs of these management strategies. METHODS We constructed a decision analytic model consisting of two treatment strategies for patients diagnosed with achalasia. Probabilities of events were systematically derived from a literature review, supplemented by expert opinion when necessary. Costs were estimated from the perspective of a third-party payer and society, including both direct and indirect costs. Future costs were discounted at a rate of 5.5% over a time horizon of 5 and 10 years. Uncertainty in the probability estimates was incorporated using probabilistic sensitivity analyses. We tested uncertainty in the model by modifying key assumptions and repeating the analysis. RESULTS From the societal perspective, the expected cost per patient was $10,789 (LM) compared with $5,315 (PD) five years following diagnosis, and $11,804 (LM) compared with $7,717 (PD) after 10 years. The 95% confidence interval of the incremental cost per patient treated with LM was ($5,280, $5,668) after five years, and ($3,863, $4,311) after 10 years. The incremental cost of LM was similar from the third-party payer perspective and in the secondary model analyzed. CONCLUSIONS Initial LM is a more costly management strategy under all clinically plausible scenarios tested in this model. Further research is needed to determine patients' preferences for the two treatment modalities, and society's willingness to bear the incremental cost of LM for those who choose it.

Abstract
BACKGROUND The present report summarizes 12 cases with achalasia treated with laparoscopic Heller myotomy and anterior fundoplication according to the method of Thal and Dor. PATIENTS AND METHODS From 1997 to 2005 at 2 institutions in Europe, 12 patients (7 male and 5 female, ages ranging from 3.5 to 7 years) were treated for esophageal achalasia (EA) with laparoscopic Heller myotomy and anterior fundoplication according to Thal and Dor. In 1 case a perforation of the esophageal mucosa occurred, which was promptly treated during surgery. Follow-up ranged from 18 to 60 months and included clinical examination and barium radiography of the upper digestive tract. RESULTS Postoperatively, 10 patients showed a normal weight curve and complete resolution of symptoms. All patients showed complete regression of digestive and respiratory symptoms from the first examination, with a normal oral meal intake and an improvement of weight and height parameters. One case required repeat intervention after 2 years because of persisting pain; in this case surgery revealed an insufficient myotomy. CONCLUSIONS Modified extramucosal Heller cardiomyotomy associated with 180 degree anterior antireflux plastic surgery (according to Thal and Dor's procedures) is a useful and safe procedure in the treatment of EA in pediatric patients. Our data, which are supported by long-term follow-up, also stress the relevance of anterior fundoplication in preventing postoperative gastroesophageal reflux.

Abstract
BACKGROUND Achalasia is a progressive motility disorder of the esophagus, without a definitive cure. The principal method of palliation is myotomy of the distal esophagus. We analyzed the 5-year experience at our institution with laparoscopic Heller myotomy without an antireflux procedure to determine its results, particularly regarding postoperative gastroesophageal reflux. MATERIALS AND METHODS Thirty-three patients, mean age 43 years (range, 29-62 years) with clinical, manometric, x-ray, and endoscopic proof of achalasia were operated on and followed up for 24 months. Prior to being referred to surgery they had all undergone at least one pneumatic balloon dilation. The operative technique was a 7-cm myotomy that included the lower esophageal sphincter but did not exceed 5 mm of the gastric cardia. Follow-up consisted of clinical observation, cineesophagography, and 24-hour pHmetry. RESULTS All patients reported satisfactory to excellent results regarding dysphagia and no heartburn two years after the operation. The 24-hour pHmetry and the radiographic investigation showed no evidence of gastroesophageal reflux. CONCLUSION It seems that the risk of gastroesophageal reflux is very low when the cardiomyotomy does not exceed the length of 5 mm. Our results are in accordance with other observational studies as well as larger cohort and meta-analysis studies. Prospective randomized studies are needed to clarify the role of an antireflux procedure after laparoscopic Heller myotomy.

Abstract
BACKGROUND Achalasia is an uncommon primary oesophageal motor disorder with an unknown aetiology. Therapeutic options for achalasia are aimed at decreasing the lower oesophageal sphincter pressure, improving the oesophageal empting, and most importantly, relieving the symptoms of achalasia. Modalities for treatment include pharmacologic, endoscopic, pneumatic dilatation and surgical. The decision of which modality to use involves the consideration of multiple clinical and economic factors. AIM To review the management strategies currently available for achalasia. METHODS A Medline search identified the original articles and reviews the published in the English language literature between 1966 and 2006. RESULTS The results reveal that pharmacotherapy, injection of botulinum toxin, pneumatic dilatation and minimally invasive surgical oesophagomyotomy are variably effective at controlling the symptoms of achalasia but that each modality has specific strengths and weaknesses which make them each suitable in certain populations. Overall, pharmacologic therapy results in the shortest lived, least durable response followed by botulinum toxin injection, pneumatic dilatation and surgery, respectively. CONCLUSION The optimal treatment for achalasia remains an area of controversy given our lack of complete understanding about the pathophysiology of the disease as well as the high numbers of clinical relapse after treatment. Further research focusing on optimal dosing of botulinum toxin injection and optimal timing of repeated graduated pneumatic dilatations could add to our knowledge regarding long-term therapy.

Abstract
OBJECTIVE Laparoscopic myotomy is the preferred treatment of achalasia. Our objectives were to assess the long-term outcome of esophageal myotomy and to identify preoperative factors influencing the outcome. METHODS Preoperative and long-term outcome data were collected from patients undergoing laparoscopic myotomy for achalasia at our institution. The primary endpoint of the study was the postoperative change (delta) in dysphagia score. This score was calculated by combining the frequency and the severity of dysphagia. Persistent postoperative dysphagia was defined as 1 standard deviation less than the mean delta score of all patients. Logistic regression was used to identify independent preoperative factors associated with successful myotomy. RESULTS A total of 200 consecutive patients were included in the study. At a mean follow-up of 42.1 months, the mean delta dysphagia score was 7.1 +/- 2.6; therefore, the myotomy was considered successful when the delta score was >4.5. According to this definition, 170 (85%) patients achieved excellent dysphagia relief (responders). Responders had higher preoperative low esophageal sphincter (LES) pressure than nonresponders: 42.6 +/- 13.1 versus 23.8 +/- 7.0 mm Hg (P = 0.001). High preoperative LES pressure remained an independent predictor of excellent response in the multivariate logistic regression model. Patients with LES pressure >35 mm Hg had an odds ratio of 21.3, making more likely to achieve excellent dysphagia relief after myotomy compared with those with LES pressure < or =35 mm Hg (odds ratio, 21.3; 95% confidence interval, 6.1-73.5, P = 0.0001). CONCLUSION Laparoscopic myotomy can durably relieve symptoms of dysphagia. Elevated preoperative LES pressure represents the strongest positive outcome predictor.

Abstract
BACKGROUND & AIMS Studies comparing long-term success after pneumatic dilatation (PD) and laparoscopic Heller myotomy (HM) are lacking. This study compares long-term outcome of PD (single dilatation and graded approach) and laparoscopic HM and identifies risk factors for treatment failure. METHODS A cross-sectional follow-up evaluation of an achalasia cohort treated between 1994 and 2002 was followed-up for a mean of 3.1 years. There was a total of 106 patients treated by graded PD (1-3 dilatations with progressively larger balloons) and 73 patients treated by HM (20 had failed graded PD and crossed over to HM). A symptom assessment (structured telephone interview or clinic visit) was performed and patients were given freedom from alternative therapies to determine treatment outcome. Endoscopy, manometry, and timed barium esophagram were performed to determine the cause of treatment failure. RESULTS The success of single PD was defined as freedom from additional PDs: 62% at 6 months and 28% at 6 years (risk factors for failure: younger age, male sex, wider esophagus, and poor emptying on posttreatment timed barium esophagram). Freedom from subsequent PDs increased with each dilatation (graded PD). The success of graded PD and HM, defined as dysphagia/regurgitation less than 3 times/wk or freedom from alternative treatment, was similar: 90% vs 89% at 6 months and 44% vs 57% at 6 years (no risk factors for failure were identified). Causes of symptom recurrence were incompletely treated achalasia (96% after PD vs 64% after HM) and gastroesophageal reflux disease (4% after PD vs 36% after HM). CONCLUSIONS No treatment cures achalasia. Short- and long-term success is similar for graded PD and laparoscopic HM. Therapeutic success decreases steadily over time. Achalasia patients need careful long-term follow-up evaluation.
