Abstract
Achalasia is a rare disorder that has several treatment options. The gold standard of treatment is a surgical myotomy called a laparoscopic Heller myotomy (LHM). More recently, an endoscopic myotomy has become an option as well, called per-oral endoscopic myotomy (POEM). An achalasia registry was queried for patients undergoing either LHM or POEM at Baylor University Medical Center at Dallas. Patient demographics, preoperative and postoperative data points, and Eckardt scores were collected. The patients were further stratified into their follow-up intervals, immediate postoperative and long-term follow-up, to assess surgical success. A subset analysis was done for success of treatment for patients who had redo surgery versus those undergoing the procedure for the first time. There were 12 patients in the POEM group and 11 patients in the LHM group. Both groups demonstrated mean lower esophageal sphincter pressures with failure to relax. Procedure length and hospital length of stay were similar between the two groups. There were three adverse events in each group, but none altered the patient's postoperative clinical course. Eckardt scores, used to assess success of the surgery, were 82% for POEM patients and 66% for LHM patients after 6 months. The outcomes for POEM and LHM in our early experience are similar to those reported in the literature for high-volume centers managing achalasia.

Abstract
Laparoscopic Heller's myotomy (LHM) and endoscopic balloon dilation are two main treatment modalities for achalasia cardia. The best treatment modality in Indian setting, however, is still unknown. Here, we present the early results of LHM in achalasia. Hospital data from January 2009 to October 2013 was analyzed. Preoperative assessment included Eckardt's scoring, esophagogastroduodenoscopy, barium swallow examination, and esophageal manometry. Thirty-five patients (19 males and 16 females, median age 31 years, range 12-65) underwent LHM with partial fundoplication (with intraoperative endoscopy). All patients had dysphagia (median duration 48 months, range 1-240), and eight (22.8 %) had chest pain. Four (11 %) patients had recurrent achalasia. Most of the patients (80 %) came from rural areas, and 68.5 % were ≤40 years of age. Fundoplication was added in all except four patients (megaesophagus in one, left lobe hepatomegaly in one, and postsurgical recurrent achalasia in two). The median operative time was 180 min (range 120-300). Intraoperative complications included esophageal mucosal injury (n = 2) and pleural breach (n = 3) with one conversion. The median postoperative stay was 7 days (range 4-27) with a morbidity of 5.7 % (leak in one and subphrenic collection in one patient) and a mortality of 1 % (due to myocardial infarction). After a median follow-up of 9.5 months (range 1-47 months), four (11.4 %) patients had recurrent dysphagia and three (8.5 %) had gastroesophageal reflux. Most of the patients (six of eight) had relief in chest pain. To conclude, predominance of rural, young, and male patients in this study suggests that LHM might be the first-line treatment for achalasia in developing countries like India where predominant population is still rural that prefers one-time treatment, though it needs to be compared with a newly described procedure per oral endoscopic myotomy (POEM).

Abstract
BACKGROUND Peroral endoscopic myotomy (POEM) is a minimally invasive yet challenging procedure for achalasia. Additional technological innovations and improvements are important for simplifying the procedure. METHODS We report the successful use of a modified POEM procedure, which utilized a "Push and Pull" technique, on a patient with achalasia. RESULTS Our modifications resulted in a short operation time of only 35 min. No complications arose during or after the procedure, up to a follow-up period of 6 months, and symptoms were significantly and quickly improved. CONCLUSIONS This modified procedure shortens operation time and lowers the difficulty of the operation, while leaving the safety and efficacy uncompromised.

Abstract
Here, we present a case of a 50-year-old male with a history of a Guillain-Barré-syndrome, who was referred to our clinic with recurrent esophageal candidiasis and long-standing intermittent retrosternal cramps for further evaluation. Other symptoms such as dysphagia, regurgitations and weight loss were denied, and prior repeated endoscopy was otherwise unremarkable. Using high resolution impedance manometry, we could demonstrate a panesophageal pressure increase on water swallows and complete aperistalsis of the tubular esophagus, indicating achalasia type II. However, due to the patient's extraordinary body height and resulting length of the esophagus, endoluminal functional lumen imaging probe analysis supplementary to high resolution impedance manometry needed to be used to assess distensibility of the esophagogastral junction and to secure the diagnosis of achalasia before appropriately treating the patient with pneumatic dilation.

Abstract
BACKGROUND & AIMS In patients with persistent symptoms after Heller myotomy (HM), treatment options include repeat HM, pneumatic dilation, or peroral endoscopic myotomy (POEM). We evaluated the efficacy and safety of POEM in patients with achalasia with prior HM vs without prior HM. METHODS We conducted a retrospective cohort study of 180 patients with achalasia who underwent POEM at 13 tertiary centers worldwide, from December 2009 through September 2015. Patients were divided into 2 groups: those with prior HM (HM group, exposure; n = 90) and those without prior HM (non-HM group; n = 90). Clinical response was defined by a decrease in Eckardt scores to 3 or less. Adverse events were graded according to criteria set by the American Society for Gastrointestinal Endoscopy. Technical success, clinical success, and rates of adverse events were compared between groups. Patients were followed up for a median of 8.5 months. RESULTS POEM was technically successful in 98% of patients in the HM group and in 100% of patients in the non-HM group (P = .49). A significantly lower proportion of patients in the HM group had a clinical response to POEM (81%) than in the non-HM group (94%; P = .01). There were no significant differences in rates of adverse events between the groups (8% in the HM group vs 13% in the non-HM group; P = .23). Symptomatic reflux and reflux esophagitis after POEM were comparable between groups. CONCLUSIONS POEM is safe and effective for patients with achalasia who were not treated successfully by prior HM. Although the rate of clinical success in patients with prior HM is lower than in those without prior HM, the safety profile of POEM is comparable between groups.

Abstract
INTRODUCTION Laparoscopic fundoplication is the gold standard treatment for gastroesophageal reflux disease (GERD) refractory to medical management. Although many studies have compared Nissen fundoplication (NF) to Toupet fundoplication (TF), it is unclear which operation provides the best long-term reflux control. The objective of this study was to evaluate long-term quality-of-life (QoL) outcomes after NF versus TF. METHODS Clinical data from our single academic institutional foregut database were used to identify patients who underwent NF or TF (June 2010 to May 2016). Postoperative QoL was assessed through telephone at 1, 3, or 5 years postsurgery, using GERD-health related quality of life (GERD-HRQL), Gastroparesis Cardinal Symptom Index (GCSI), and Eckardt Dysphagia scores. Proton pump inhibitor (PPI) use and satisfaction with surgery were also obtained. Trends in outcomes over time were analyzed by logistic regression or Cochran-Armitage trend test. RESULTS Our cohort included 155 TF and 161 NF patients. TF patients reported baseline dysphagia at higher rates (42.6% versus 19.9%; P < .001) and had worse preoperative esophageal dysmotility than NF patients. There were no significant differences in GERD-HRQL or GCSI scores between TF and NF patients at any time point postoperatively. Long-term satisfaction was equivalent between TF and NF patients 5 years postoperatively (70.0% versus 77.4%; P = .67). NF patients had higher Eckardt dysphagia scores 1 year after surgery compared to TF patients, but this difference was not present at 3 or 5 years postoperatively. Over time, PPI use increased and there was a trend toward increased GERD-HRQL scores in the TF group. CONCLUSIONS Both TF and NF provide excellent long-term satisfaction for patients with GERD. NF and TF patients reported similar postoperative QoL scores. Our finding of increasing PPI use and a trend toward worsening GERD scores following TF warrants additional investigation regarding the long-term durability of TF.

Abstract
PURPOSE OF REVIEW This review aims to shed light on subtleties of achalasia diagnosis, including potential pitfalls that may lead to errors. Optimal methods for assessment of disease severity and the relationship between achalasia and other motility disorders will also be reviewed with an emphasis on recent findings from the literature. RECENT FINDINGS Adjunctive testing with viscous substances or larger water volumes should be used routinely as it improves the accuracy of achalasia diagnosis. Chronic opiate use can mimic achalasia. The timed barium swallow remains the best test for assessments of disease severity and prognostication, but the functional lumen-imaging probe, a newer tool which measures esophagogastric junction distensibility using impedance planimetry, is emerging as a potentially more powerful tool for these purposes. Functional esophagogastric junction outflow obstruction is possibly part of the achalasia spectrum. By addressing the potential pitfalls described, and through routine and standardized use of the diagnostic tools mentioned herein, the accuracy of diagnosis, severity assessment, and prognostication of achalasia can be improved.

Abstract
BACKGROUND Laparoscopic antireflux surgery (LARS) is the gold standard treatment for refractory gastroesophageal reflux disease (GERD). Traditional surgical outcomes following LARS are well described, but limited data exist regarding patient-reported outcomes. We aimed to identify preoperative characteristics that were independently associated with a high GERD health-related quality of life (GERD-HRQL) following LARS. METHODS Clinical data from our single institution foregut surgery database were used to identify all patients with GERD who underwent primary LARS from June 2010 to November 2015. Electronic health record data were reviewed to extract patient characteristics, diagnostic study characteristics, and operative data. Postoperative GERD-HRQL data were obtained through telephone follow-up. Variables hypothesized a priori to be associated with high GERD-HRQL after LARS, which were significant at P ≤ .2 on bivariate analysis, were entered into a multivariable linear regression model with GERD-HRQL as the outcome. RESULTS The study included 248 patients; 69.0% were female, 56.9% were married, and 58.1% had concurrent atypical symptoms. The most commonly performed fundoplications were Nissen (44.8%), Toupet (41.3%), and Dor (14.1%), respectively. The median follow-up interval was 3.4 years. The telephone response rate was 60.1%. GERD-HRQL scores improved from 24.8 (SD ±11.4) preoperatively to 3.0 (SD ±5.9) postoperatively. 79.9% of patients were satisfied with their condition at follow-up. On multivariable analysis, being married (P = .04) and absence of depression (P = .02) were independently associated with a higher postoperative QoL. CONCLUSIONS Strong social support and psychiatric well-being appear to be important predictors of a higher QoL following LARS. Optimizing social support and treating depression preoperatively and postoperatively may improve QoL outcomes for LARS patients.

Abstract
Peroral endoscopic myotomy (POEM) has been widely applied to the treatment of achalasia. The aim of this study is to retrospectively investigate the long-term outcome of POEM in patients with achalasia. Patients undergoing POEM at our center with a minimum follow-up of 3 years were enrolled in this study. Relief of patients' symptom was defined as the primary outcome. Secondary outcomes included lower esophageal sphincter pressure, esophageal emptying, symptoms relapse, and clinical reflux adverse events. The Chi-square test was performed to determine the potential predictors of surgical failure. Sixty-seven patients (aged 40.7 ± 15.3 years) were recruited in the study, with a mean follow-up period of 40.1 ± 2.8 months. At the final follow-up, the median Eckardt score reduced from 7.6 ± 2.3 preoperatively to 1.9 ± 1.7 (P < 0.001), the lower esophageal sphincter pressure was reduced from 35.4 ± 13.7 mmHg preoperatively to 8.9 ± 4.1 mmHg (P < 0.001), and the height of the barium column at 5 min after barium swallowed was reduced from 9.7 ± 1.6 cm preoperatively to 2.9 ± 2.1 cm (P < 0.001). Eight patients had symptoms relapse and nine patients developed reflux esophagitis. Type III achalasia was found to be indicative of surgical failure. POEM was a promising treatment for patients with achalasia, which can yield a long-term relief of the symptom and a low rate of clinical reflux adverse events.

Abstract
AIM to add convincing evidence to the best treatment of achalasia by comparing peroral esophageal myotomy (POEM) with laparoscopic Heller's myotomy (LHM) with regard to clinical efficacy and safety.
METHODS The databases including PubMed, EMBASE, the Cochrane Library, Web of Science, CNKI and China Science and Technology Journal Database were fully searched for relevant articles published in Chinese and English form database inception to February 20, 2016. The data were analyzed using Review Manager version 5.3 software. To assess the variation across studies, heterogeneity was measured with the I2 index and Q test.
RESULTS Eight non-randomized comparative studies that included a total of 574 patients (245 in the POEM group and 329 in the LHM group) met our research criteria and were assessed. Meta-analysis results were showed as follows: (1) clinical effect: the POEM group had a better result than the LHM group (RR = 1.14, 95%CI: 1.02-1.27, P = 0.02) with high between-study homogeneity (P = 0.60, I2 = 0%); (2) major complications: There was no difference between the POEM group and LHM group (RR = 1.16, 95%CI: 0.76-1.78, P = 0.49) with high between-study homogeneity (P = 0.43, I2 = 0%); (3) all complications: No significant difference was detected between the POEM group and LHM group (RR = 0.99, 95%CI: 0.72-1.36, P = 0.94). Moderate heterogeneity existed among the included studies (P = 0.12, I2 = 39%); (4) length of hospital stay: There was no statistical difference between the two groups (MD = -0.46, 95%CI: -1.09-0.16, P = 0.14) with high between-study heterogeneity (P = 0.0007, I2 = 76%); (5) operative time: The outcome showed no significant difference between the POEM group and LHM group (MD = -35.45, 95%CI: -87.01-16.10, P = 0.18) with high heterogeneity (P < 0.00001, I2 = 98%).
CONCLUSION POEM is superior to LHM in terms of short-term clinical efficacy. It is still inconclusive on whether POEM is the best therapy for achalasia or not. Long-time follow-up studies are needed to solve this issue in the future.

Abstract
With advances in natural orifice transluminal endoscopic surgery, peroral endoscopic myotomy (POEM) has become a novel treatment for esophageal achalasia. In this study, we investigated the feasibility and safety of POEM in patients with achalasia after failed endoscopic interventions. Data on all patients undergoing POEM treatment of achalasia were collected prospectively. We enrolled 61 patients who underwent POEM for achalasia between July 2011 and January 2014. The preoperative intervention group included patients who had undergone botulinum toxin injection or pneumatic balloon dilation before POEM. The preoperative, operative, and short-term outcome data between the groups were compared. Among preoperative intervention group, 22 patients received endoscopic therapy before being referred for operation (18 dilation only, 2 botulinum toxin only, and 2 both treatments). Procedure time in the preoperative intervention group was similar to the nonpreoperative intervention group (60.8 ± 30.9 vs. 62.0 ± 21.0 minutes, P = 0.863). Both groups demonstrated significant improvement in Eckardt scores and manometric outcomes at 1-year follow-up. There were no significant differences in pretreatment and posttreatment D-values of symptom scores and lower esophageal sphincter pressures between groups (6.2 ± 2.2 vs. 6.1 ± 1.8, P = 0.840; 27.9 ± 17.6 vs. 24.9 ± 15.2; P = 0.569). There was also no significant difference in the incidence of intraoperative complications (P = 0.958) and gastroesophageal reflux rate (23.5% vs. 20.0%, P = 0.771) between the two groups. Our study demonstrated that POEM is safe and effective, even for treating achalasia in the setting of failed endoscopic interventions.

Abstract
Aim It is recommended that management of complex benign upper gastrointestinal pathology is discussed at multi disciplinary team (MDT) meetings. American College of Gastroenterology (ACG) guidelines further recommend that treatment delivery is provided by high volume centres, with objective post-procedural investigations, in order to improve patient outcomes. We aimed to survey the current UK practice in the management of achalasia. Methods 443 Upper gastrointestinal (UGI) specialist surgeons throughout the UK were sent a surveymonkey.com questionnaire about the management of achalasia. Results 100 responses were received. The majority of patients with achalasia are referred directly to surgeons (80%) and only 15% of units have a MDT meeting for discussing such patients. Diagnosis was mainly with oesophagogastroduodenoscopy (OGD) and contrast swallow, and only 61% of units have access to high resolution manometry (HRM). 89% of younger patients were offered surgery initially, whilst in the elderly surgery was offered as first line treatment in 55%. Partial fundoplication was carried out by 91% of responders as part of the operation, and 58% responders carry out an intraoperative OGD. The average number of operations carried out per annum is 4 per responder. Most responders (66%) did not perform routine post-intervention investigations and follow-up varied from none to lifelong. Conclusion Diagnosis and management of achalasia within the UK is relatively standardised, although there remains limited access to HRM. Discussion at benign MDTs however is poor and follow-up differs widely. UK guidelines may help to make these more uniform. Questionnaire to UK Upper GI specialists on achalasia management. No current UK guidelines. NICE guidelines refer to 2011 SAGES guidelines. Only 15% have benign MDT to discuss complex achalasia cases. Disparities in management with deviations from current US guidelines.

Abstract
Background/Aims Achalasia cardia (AC) is a motility disorder, characterized by impaired lower esophageal sphincter relaxation and absence of esophageal peristalsis. AC is rare in children with unclear optimum management strategies. Per oral endoscopic myotomy (POEM) is a novel technique for management of achalasia with encouraging results in adult patients. The efficacy and safety of POEM is not known for pediatric AC. The aim of our study was to evaluate the safety and efficacy of POEM in children with achalasia cardia Methods The data of all children (< 18 years) who underwent POEM at our center was retrospectively analysed. Symptoms were analysed using a validated score (Eckardt score) at regular predefined intervals. Objective parameters including high-resolution manometry, timed barium swallow and esophagogastroduodenoscopy were assessed before the procedure and at 1-year follow-up. Clinical success was defined as an Eckardt score ≤ 3. Results A total of 15 children underwent POEM during the specified period. Ten out of 15 (10/15) completed 1-year follow-up. Median operative time was 100 (38–240) minutes. Mean pre and post procedure LES pressure were 36.64 ± 11.08 mmHg and 15.65 ± 5.73 mmHg, respectively (P = 0.001). Mean Eckardt score before and after the POEM was 7.32 ± 1.42 and 1.74 ± 0.67, respectively (P = 0.001). Mean percentage improvement in barium emptying at 5 minutes was 63.70 ± 4.46%. All children had complete resolution of symptoms at 1 year. Median weight gain of children at 1 year was 0.65 kg (range, 0.0–4.6). Conclusions POEM is safe and effective for children and adolescents with achalasia. Future trials with larger sample size are warranted to establish its efficacy in pediatric AC.

Abstract
BACKGROUND Surgical management of esophageal achalasia (EA) in children has transitioned over the past 2 decades to predominantly involve laparoscopic Heller myotomy (LHM) or minimally invasive surgery (MIS). More recently, peroral endoscopic myotomy (POEM) has been utilized to treat achalasia in children. Since the overall experience with surgical management of EA is contingent upon disease incidence and surgeon experience, the aim of this study is to report a single institutional contemporary experience for outcomes of surgical treatment of EA by LHM and POEM, with regards to other comparable series in children. METHODS An IRB approved retrospective review of all patients with EA who underwent treatment by a surgical approach at a tertiary US children's hospital from 2006 to 2015. Data including demographics, operative approach, Eckardt scores pre- and postoperatively, complications, outcomes, and follow-up were analyzed. RESULTS A total of 33 patients underwent 35 operative procedures to treat achalasia. Of these operations; 25 patients underwent laparoscopic Heller myotomy (LHM) with Dor fundoplication; 4 patients underwent LHM alone; 2 patients underwent LHM with Thal fundoplication; 2 patients underwent primary POEM; 2 patients who had had LHM with Dor fundoplication underwent redo LHM with takedown of Dor fundoplication. Intraoperative complications included 2 mucosal perforations (6%), 1 aspiration, 1 pneumothorax (1 POEM patient). Follow ranged from 8months to 7years (8-84months). There were no deaths and no conversions to open operations. Five patients required intervention after surgical treatment of achalasia for recurrent dysphagia including 3 who underwent between 1 and 3 pneumatic dilations; and 2 who had redo LHM with takedown of Dor fundoplication with all patients achieving complete resolution of symptoms. CONCLUSIONS Esophageal achalasia in children occurs at a much lower incidence than in adults as documented by published series describing the surgical treatment in children. We believe the MIS surgical approach remains the standard of care for this condition in children and describe the surgical outcomes and complications for LHM, as well as, the introduction of the POEM technique in our center for treating achalasia. Our institutional experience described herein represents the largest in the "MIS era" with excellent results. We will refer to alterations in our practice that have included the use of flexible endoscopy in 100% of LHM cases and use of the endoscopic functional lumen imaging probe (EndoFLIP) in both LHM and POEM cases which we believe enables adequate Heller myotomy.

Abstract
Achalasia is a primary esophageal motility disorder. It is the absence of peristalsis in the esophageal body and inability of the lower esophageal sphincter to relax, which characterizes this rare condition. Its features typically include dysphagia, regurgitation, chest pain, and weight loss. The ultimate goal in treating achalasia is to relieve the patient's symptoms, improve esophageal emptying, and prevent further dilatation of the esophagus. Current treatment modalities targeted at achalasia include pharmacological therapy, endoscopic therapy, and surgery. This review focuses on the current therapeutic options and explores the role of peroral endoscopic myotomy in the management armamentarium.

Abstract
BACKGROUND Peroral endoscopic myotomy (POEM) has been introduced as a novel endoscopic treatment for achalasia. The aim of this work is to assess the changes in esophageal motility caused by POEM in patients with achalasia. METHODS Forty-one patients with achalasia underwent POEM from September 2012 to November 2014. Esophageal motility of all patients was evaluated preoperatively and 1 month after POEM utilizing high-resolution manometry, which was performed with ten water swallows, ten steamed bread swallows, and multiple rapid swallows (MRS). RESULTS In single swallows, including liquid swallows and bread swallows, all the parameters of lower esophagus sphincter resting pressure (LESP), 4-s integrated relaxation pressure (4sIRP), and intra-bolus pressure (IBP) were decreased between pre- and post-POEM patients (all p < 0.05). Postoperatively, the trend of distal contractile integral (DCI) and distal esophageal peristaltic amplitude declined in subtype II and subtype III (subtype II: p < 0.05; subtype III: p > 0.05), but increased in subtype I (subtype I: p > 0.05). In liquid swallows, the Eckardt score of subtype II patients decreased with DCI, and distal esophageal peristaltic amplitude after POEM was significantly lower compared with those showing increased values of those two parameters (p < 0.05). In MRS, the rate of LES relaxation increased from 66.67 to 95.24%, but without normal response in all achalasia patients. CONCLUSIONS POEM reduces LES pressure in achalasia, and partly restores esophageal motility. POEM displayed varying effect on esophageal motility in patients with different patterns of swallowing. In addition, the changes in parameters associated with esophageal peristalsis correlated with decreases in Eckardt score.

Abstract
OBJECTIVE To assess manometric subtypes as predictive factors for the treatment efficacies of pneumatic balloon dilatation (PBD) and laparoscopic Heller myotomy (LHM) in patients with achalasia. METHODS A systematic search of the Pubmed, Embase and Cochrane Library database was conducted to identify relevant publications on high-resolution manometric subtypes and different therapies for achalasia with predefined inclusion and exclusion criteria. Data on the success rates after PBD or LHM for different manometric subtypes were extracted. The pooled odds ratio (OR) and 95% confidence interval (CI) for different manometric subtypes were estimated using STATA 13.0. RESULTS In all, nine studies met the inclusion criteria. A total of 298 patients having achalasia receiving PBD and 429 undergoing LHM were included in the meta-analysis. The pooled OR between the subtypes of achalasia after PBD or LHM showed that the best and worse treatment outcomes were found in patients with type II and III achalasia, respectively (type I vs type II after PBD: OR 0.16, 95% CI 0.08-0.36, P = 0.000; type I vs type III after PBD: OR 3.64, 95% CI 1.55-8.53, P = 0.003; type II vs type III after PBD: OR 27.18, 95% CI 9.08-81.35, P = 0.000; type I vs type II after LHM: OR 0.26, 95% CI 0.12-0.56, P = 0.001; type I vs type III after LHM: OR 1.89, 95% CI 0.80-4.50, P = 0.148; type II vs type III after LHM: OR 6.86, 95% CI 2.72-17.28, P = 0.000). CONCLUSION Type II achalasia shows the best prognosis after PBD and LHM, while type III achalasia has the worst prognosis.

Concurrent myotomy and tunneling after establishment of a half tunnel instead of myotomy after establishment of a full tunnel: a more efficient method of peroral endoscopic myotomy. Endosc Int Open 2016; 4:E403-8. [PMID: 27092318 PMCID: PMC4831933 DOI: 10.1055/s-0042-101787] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/28/2015] [Accepted: 01/05/2016] [Indexed: 12/12/2022] Open
Abstract
BACKGROUND AND STUDY AIMS Peroral endoscopic myotomy (POEM) is a time-consuming and challenging procedure. Traditionally, the myotomy is done after the submucosal tunnel has been completed. Starting the myotomy earlier, after submucosal tunneling is half completed (concurrent myotomy and tunneling), may be more efficient. This study aims to assess if the method of concurrent myotomy and tunneling may decrease the procedural time and be efficacious. PATIENTS AND METHODS This is a retrospective case series of patients who underwent modified POEM (concurrent myotomy and tunneling) or traditional POEM at a tertiary care medical center. Modified POEM or traditional POEM was performed at the discretion of the endoscopist in patients presenting with achalasia. The total procedural duration, myotomy duration, myotomy length, and time per unit length of myotomy were recorded for both modified and traditional POEM. RESULTS Modified POEM was performed in 6 patients whose mean age (± standard deviation [SD]) was 58 ± 13.3 years. Of these, 5 patients had type II achalasia and 1 patient had esophageal dysmotility. The mean Eckardt score (± SD) before the procedure was 8.8 ± 1.3. The modified technique was performed in 47 ± 8 minutes, with 6 ± 1 minutes required per centimeter of myotomy and 3 ± 1 minutes required per centimeter of submucosal space. The Eckardt score was 3 ± 1.1 at 1 month and 3 ± 2.5 at 3 months. The procedure time for modified POEM was significantly shorter than that for traditional POEM. CONCLUSIONS Modified POEM with short submucosal tunneling may be more efficient than traditional POEM with long submucosal tunneling, and outcomes may be equivalent over short-term follow-up. Long-term data and randomized controlled studies are needed to compare the clinical efficacy of modified POEM with that of the traditional method.

Abstract
BACKGROUND Previous randomized controlled trials have demonstrated that partial fundoplication following Heller myotomy results in less pathologic acid exposure to the esophagus when compared to myotomy without fundoplication. Recent studies have questioned the necessity of a fundoplication, especially when a limited hiatal dissection (LHD) is performed and the angle of His is preserved. MATERIALS AND METHODS This is a retrospective review of prospectively maintained data. All patients underwent primary Heller myotomy for achalasia over a 30-month period. In select patients, an LHD was performed anteriorly. Symptomatic outcomes were assessed up to 2 years postoperation using the Achalasia Severity Questionnaire (ASQ), Gastrointestinal Quality of Life Index (GIQLI), and Gastroesophageal Reflux Disease-Health-Related Quality of Life (GERD-HRQL). RESULTS A total of 31 patients underwent Heller myotomy during the study interval. The majority of patients underwent Heller myotomy with full hiatal dissection (FHD) (21, 68%). Intraoperative mucosal perforations occurred in 3 (14%) patients undergoing FHD. Patient demographics, surgery details, and baseline symptomatic outcomes did not differ significantly preoperatively. At greater than 1 year postoperation, there was no significant difference between the groups for ASQ, GERD-HRQL, and GIGLI (P = .76, .78, and .33, respectively). CONCLUSIONS Heller myotomy with LHD and no fundoplication and Heller myotomy with FHD and partial fundoplication result in similar GERD-related quality of life outcomes. Further studies (including pH studies) are necessary to determine if fundoplication is a necessary step in selected patients in whom an LHD is possible.

Abstract
BACKGROUND Achalasia is classified into three HRM subtypes that predict outcomes from diverse management strategies. We assessed if symptomatic response varied when a single management strategy-Heller myotomy (HM)-is employed. METHODS Treatment-naive subjects with achalasia referred for HM were followed in this observational cohort study. Chicago criteria designated achalasia subtypes (subtype I: no esophageal pressurization; subtype II: panesophageal pressurization in ≥20 % swallows; subtype III: premature contractions in ≥20 % swallows). Symptom questionnaires assessed symptom burden before and after HM on five-point Likert scales (0 = no symptoms, 4 = severe symptoms) and on 10-cm visual analog scales (global symptom severity, GSS); satisfaction with HM was recorded similarly. Data were analyzed to determine predictors of GSS change across subtypes. RESULTS Sixty achalasia subjects (56.1 ± 2.4 years, 55 % female) fulfilled inclusion criteria, 15 % with subtype I, 58 % with subtype II, and 27 % with subtype III achalasia. Baseline symptoms included dysphagia (solids: 85 %, liquids: 73 %), regurgitation (84 %), and chest pain (35 %); mean GSS was 7.1 ± 0.3. Upon follow-up 2.1 ± 0.2 years after HM, GSS declined to 1.9 ± 0.4 (p < 0.001), with surgical satisfaction score of 8.7 ± 0.3 out of 10; these were similar across achalasia subtypes. On univariate analysis, female gender, Eckardt score, severity of transit symptoms, and maximal IRP predicted linear GSS improvement; female gender (p = 0.003) and dysphagia for liquids (p = 0.043) remained predictive on multivariate analysis. CONCLUSIONS When a uniform surgical approach is utilized, symptomatic outcome and satisfaction with therapy are similar across achalasia subtypes. Female gender and severity of dysphagia for solids may predict better HM outcome.

Abstract
BACKGROUND AND AIM Peroral endoscopic myotomy (POEM) is a recently introduced technique for the treatment of achalasia cardia (AC). Data regarding safety and efficacy are still emerging. We report our experience of POEM emphasizing its safety, efficacy and follow-up data. METHODS Patients with AC (220; mean age 39 years, range 9-74 years) underwent POEM from January 2013 to August 2014 for AC. Retrospective analysis of prospectively collected data was done. POEM was carried out by the standard technique of mucosal incision, submucosal tunneling, and myotomy of the esophageal and gastric muscle bundles followed by closure of the mucosal incision by hemoclips. Eckardt score, high-resolution manometry (HRM) and timed barium esophagogram (TBE) were used to evaluate the results. Post-procedure patients were followed up. RESULTS Technical success rate of POEM was 96%. At 1 year, clinical success rate was 92%. Mean Eckardt score was 7.2 ± 1.55 prior to POEM and 1.18 ± 0.74 after POEM (P = 0.001). There was significant improvement of esophageal emptying on TBE (38.4 ± 14.0 % vs 71.5 ± 16.1 % (P = 0.001). Pre-procedure and post-procedure mean lower esophageal sphincter pressure was 37.5 ± 14.5 mmHg and 15.2 ± 6.3 mmHg, respectively. (P = 0.001) Erosive esophagitis was seen in 16% of patients who underwent POEM. There were no major adverse events. CONCLUSIONS Study demonstrates excellent safety profile of POEM with significant relief of symptoms, reduced pressure at HRM and improved emptying at TBE. Further prospective studies are required to compare with other treatment modalities.

Abstract
Background and Aims. We initiated peroral endoscopic myotomy (POEM) utilizing a two-person technique with combination of an advanced endoscopist and a thoracic surgeon with complementary skills. Our aim was to determine the feasibility and outcomes in initial 20 patients. Methods. In this observational study, main outcomes measured were therapeutic success in relieving symptoms (Eckardt score < 3), decrease in lower esophageal sphincter (LES) pressures, improvement in emptying on timed barium esophagogram (TBE), and complications. Results. POEM was successful in all 20 patients with a mean operative time of 140.1 + 32.9 minutes. Eckardt symptom scores decreased significantly at two-month follow-up (6.4 + 2.9 versus 0.25 + 0.45, p < 0.001). Both basal and residual LES pressures decreased significantly (28.2 + 14.1 mmHg versus 12.8 + 6.3 and 22.4 + 11.3 versus 6.3 + 3.4 mmHg, p = 0.025 and <0.001, resp.). Barium column height at 5 minutes on TBE reduced from 6.8 + 4.9 cm to 2.3 + 2.9 cm (p = 0.05). Two patients (10%) had mucosal perforations and one had delayed bleeding (5%). Conclusions. Two-person technique of POEM with combination of an advanced endoscopist and a thoracic surgeon is highly successful with low risk of complications.

Abstract
BACKGROUND Peroral endoscopic myotomy (POEM) has been described as a novel treatment for esophageal achalasia. Owing to its technical difficulty, POEM is not widely performed. This study was aimed to prospectively assess the factor predicting technical difficulty of POEM in a single center with large volume cases. METHODS A total of 105 cases of achalasia treated by POEM from April 2011 to September 2014 were analyzed. Difficult cases of POEM were defined as procedure time ≥90 min and occurrence of adverse events, including mucosal perforation, pneumothorax, and major bleeding. Univariate and multivariate logistic regression analyses were performed to assess the predictive factors of difficult POEM. RESULTS POEM was successfully completed in all the patients, and no one was converted to laparoscopy. The number of cases with procedure time ≥90 min was 17. Mucosal perforations occurred in six (5.7 %) patients during submucosal tunnel creation, major bleeding occurred in seven (6.7 %) patients, and pneumothorax occurred in six (5.7 %) patients immediately after procedure. All the complications were managed conservatively. No other intraoperative and immediate postoperative complications, including infections and pneumoperitoneum, occurred. Multivariate analysis showed that early period (odds ratio [OR] 4.173, 95 % confidence interval [95 % CI] 1.36-6.829, P = 0.023) and triangular tip knife ([OR] 6.712, [95 % CI] 1.479-30.460, P = 0.014) were independent factors associated with technical difficulty regarding longer procedure time (procedure time ≥90 min). CONCLUSION POEM is safe for the treatment of esophageal achalasia. Triangular tip knife and early period were independent risk factors for longer procedural time.

Abstract
This article reviews currently available pharmacological options available for the treatment of achalasia, with a special focus on the role of botulinum toxin (BT) injection due to its superior therapeutic effect and side effect profile. The discussion on BT includes the role of different BT serotypes, better pharmacological formulations, improved BT injection techniques, the use of sprouting inhibitors, designer recombinant BT formulations and alternative substances used in endoscopic injections. The large body of ongoing research into achalasia and BT may provide a stronger role for BT injection as a form of minimally invasive, cost effective and efficacious form of therapy for patients with achalasia. The article also explores current issues and future research avenues that may prove beneficial in improving the efficacy of pharmacological treatment approaches in patients with achalasia.

Abstract
BACKGROUND Timed barium esophagogram (TBE) and esophageal transit scintigraphy (ETS) have been adopted as useful ways to evaluate achalasia patients. TBE has merit as a simple, non-invasive, and convenient method. AIMS The study sought to compare the results of these two tests and verify their usefulness in evaluating treatment response. In addition, we assessed whether TBE could effectively replace ETS through correlation analysis. METHODS The medical records of 50 achalasia patients treated between September 2011 and June 2014 were reviewed retrospectively. The height and width of the barium column at 1, 2, and 5 min were measured by TBE. Half-life (T 1/2, min) and R 30 (percentage of remaining radioactivity 30 s after radioisotope ingestion) were measured by ETS. Both tests were performed before and after treatment, and the tests were carried out 1 and 2 days after procedures. And we analyzed the correlation between the parameters from the two tests. RESULTS The parameters of TBE and ETS were improved after treatment (p < 0.05). Before treatment, the height and width results at 5 min from TBE positively correlated with the T 1/2 parameter from ETS (correlation coefficients of 0.59 and 0.75, respectively). After treatment, the correlation coefficients between the 5-min height and width of the barium column by TBE and T 1/2 by ETS were 0.55 and 0.46, respectively. CONCLUSIONS Both TBE and ETS are useful modalities in assessing esophageal emptying and response to achalasia treatment. TBE and ETS results have a statistically significant correlation both pre- and post-treatment. We suggest that TBE could effectively replace ETS for the assessment of achalasia.

Abstract
Idiopathic achalasia is a primary esophageal motor disorder characterized by loss of esophageal peristalsis and insufficient lower esophageal sphincter relaxation in response to deglutition. Patients with achalasia commonly complain of dysphagia to solids and liquids, bland regurgitation often unresponsive to an adequate trial of proton pump inhibitor, and chest pain. Weight loss is present in many, but not all patients. Although the precise etiology is unknown, it is often thought to be either autoimmune, viral immune, or neurodegenerative. The diagnosis is based on history of the disease, barium esophagogram, and esophageal motility testing. Endoscopic assessment of the gastroesophageal junction and gastric cardia is necessary to rule out malignancy. Newer diagnostic modalities such as high resolution manometry help in predicting treatment response in achalasia based on esophageal pressure topography patterns identifying three phenotypes of achalasia (I-III) and outcome studies suggest better treatment response with types I and II compared to type III. Although achalasia cannot be permanently cured, excellent outcomes are achieved in over 90 % of patients. Current medical and surgical therapeutic options (pneumatic dilation, endoscopic and surgical myotomy, and pharmacologic agents) aim at reducing the LES pressure and facilitating esophageal emptying by gravity and hydrostatic pressure of retained food and liquids. Either graded pneumatic dilatation or laparoscopic surgical myotomy with a partial fundoplication are recommended as initial therapy guided by patient age, gender, preference, and local institutional expertise. The prognosis in achalasia patients is excellent. Most patients who are appropriately treated have a normal life expectancy but the disease does recur and the patient may need intermittent treatment.

Abstract
PURPOSE To assess the short-term efficacy and quality of life (QOL) of patients with achalasia after peroral endoscopic myotomy (POEM). METHODS Thirty-five achalasia patients underwent POEM from May 2013 to December 2013. The data on clinical evaluation and QOL before therapy, at 1 month and 6 months postoperation were collected and analyzed. RESULTS All the thirty-five patients underwent POEM successfully. By comparing the data of the preoperative with that of 1 month and 6 months after POEM respectively, we found that: mean Eckardt score decreased (6.83 vs 0.51, 6.83 vs 0.46, all P <0.05), esophagus diameter reduced (47.97 mm vs 32.00 mm, 47.97 mm vs 28.50 mm, all P <0.05), and esophageal manometry declined (29.5 mmHg vs 11.5 mmHg, 29.5 mmHg vs 10.3 mmHg, all P <0.05). Complications occurred in 14.3% (5/35) of the cases, and no recurrence was observed. At each time point, postoperative QOL scores were higher than those of preoperative (P <0.05). CONCLUSIONS POEM is safe and effective for treating achalasia in the short-term, it can relieve clinic symptoms as well as improve patients' QOL.

Abstract
Achalasia is an esophageal motility disorder that is commonly misdiagnosed initially as gastroesophageal reflux disease. Patients with achalasia often complain of dysphagia with solids and liquids but may focus on regurgitation as the primary symptom, leading to initial misdiagnosis. Diagnostic tests for achalasia include esophageal motility testing, esophagogastroduodenoscopy and barium swallow. These tests play a complimentary role in establishing the diagnosis of suspected achalasia. High-resolution manometry has now identified three subtypes of achalasia, with therapeutic implications. Pneumatic dilation and surgical myotomy are the only definitive treatment options for patients with achalasia who can undergo surgery. Botulinum toxin injection into the lower esophageal sphincter should be reserved for those who cannot undergo definitive therapy. Close follow-up is paramount because many patients will have a recurrence of symptoms and require repeat treatment.

Abstract
Achalasia is an oesophageal motor disorder which leads to the functional obstruction of the lower oesophageal sphincter (LES) and is currently incurable. The main objective of all existing therapies is to achieve a reduction in the obstruction of the distal oesophagus in order to improve oesophageal transit, relieve the symptomatology, and prevent long-term complications. The most common treatments used are pneumatic dilation (PD) and laparoscopic Heller myotomy, which involves partial fundoplication with comparable short-term success rates. The most economic non-surgical therapy is PD, with botulinum toxin injections reserved for patients with a higher surgical risk for whom the former treatment option is unsuitable. A new technology is peroral endoscopic myotomy, postulated as a possible non-invasive alternative to surgical myotomy. Other endoluminal treatments subject to research more recently include injecting ethanolamine into the LES and using a temporary self-expanding metallic stent. At present, there is not enough evidence permitting a routine recommendation of any of these three novel methods. Patients must undergo follow-up after treatment to guarantee that their symptoms are under control and to prevent complications. Most experts are in favour of some form of endoscopic follow-up, however no established guidelines exist in this respect. The prognosis for patients with achalasia is good, although a recurrence after treatment using any method requires new treatment.

Abstract
BACKGROUND AND STUDY AIMS Type III achalasia is characterized by rapidly propagating pressurization attributable to spastic contractions. Although laparoscopic Heller myotomy (LHM) is the current gold standard management for type III achalasia, peroral endoscopic myotomy (POEM) is conceivably superior because it allows for a longer myotomy. Our aims were to compare the efficacy and safety of POEM with LHM for type III achalasia patients. PATIENTS AND METHODS A retrospective study of 49 patients who underwent POEM for type III achalasia across eight centers were compared to 26 patients who underwent LHM at a single institution. Procedural data were abstracted and pre- and post-procedural symptoms were recorded. Clinical response was defined by improvement of symptoms and decrease in Eckardt stage to ≤ 1. Secondary outcomes included length of myotomy, procedure duration, length of hospital stay, and rate of adverse events. RESULTS Clinical response was significantly more frequent in the POEM cohort (98.0 % vs 80.8 %; P = 0.01). POEM patients had significantly shorter mean procedure time than LHM patients (102 min vs 264 min; P < 0.01) despite longer length of myotomy (16 cm vs 8 cm; P < 0.01). There was no significant difference between POEM and LHM in the length of hospital stay (3.3 days vs 3.2 days; P = 0.68), respectively. Rate of adverse events was significantly less in the POEM group (6 % vs 27 %; P < 0.01). CONCLUSIONS POEM allows for a longer myotomy than LHM, which may result in improved clinical outcomes. POEM appears to be an effective and safe alternative to LHM in patients with type III achalasia.

Abstract
BACKGROUND Peroral endoscopic myotomy (POEM) has been developed to provide a less-invasive myotomy for achalasia in adults but seldom has been used in pediatric patients. OBJECTIVE To evaluate the feasibility, safety, and efficacy of POEM for pediatric patients with achalasia. DESIGN Single-center, prospective study. SETTING Academic medical center. PATIENTS A total of 27 pediatric patients (mean age 13.8 years, range 6-17 years) with achalasia. INTERVENTIONS POEM MAIN OUTCOME MEASUREMENTS The primary outcome was symptom relief during follow-up, defined as an Eckardt score of ≤3. Secondary outcomes were procedure-related adverse events, clinical reflux adverse events, and lower esophageal sphincter (LES) pressure on manometry before and after POEM. RESULTS A total of 26 cases (96.3%) underwent successful POEM. A submucosal tunnelling attempt failed in 1 case because of serious inflammation and adhesion. No serious adverse events related to POEM were encountered. During a mean follow-up period of 24.6 months (range 15-38 months), treatment success was achieved in all patients (mean score before vs after treatment 8.3 vs 0.7; P < .001). Mean LES pressure also decreased from a mean of 31.6 mm Hg to 12.9 mm Hg after POEM (P < .001). Five patients developed clinical reflux adverse events (19.2%). LIMITATIONS Single center and lack of some objective evaluations. CONCLUSION This relatively long-term follow-up study adds to the evidence that POEM seems to be a promising new treatment for pediatric patients with achalasia, resulting in long-term symptom relief in all cases and without serious adverse events.

Peroral endoscopic myotomy for advanced achalasia with sigmoid-shaped esophagus: long-term outcomes from a prospective, single-center study. Surg Endosc 2014; 29:2841-50. [PMID: 25492452 DOI: 10.1007/s00464-014-4013-9] [Citation(s) in RCA: 59] [Impact Index Per Article: 5.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2014] [Accepted: 11/10/2014] [Indexed: 12/14/2022]
Abstract
BACKGROUND The sigmoid-shaped esophagus is considered to be the advanced stage of achalasia, in which the esophageal lumen is significantly dilated, swerved, and rotated. In consideration of the efficacy of peroral endoscopic myotomy (POEM) for early achalasia, it may also offer another option for the treatment of advanced achalasia with sigmoid-shaped esophagus. Our purpose was to evaluate the feasibility and long-term efficacy of POEM for patients with sigmoid-type achalasia. METHODS 32 consecutive patients with sigmoid-type achalasia (S1 type in 29 patients and S2 type in 3 patients) were prospectively included. Primary outcome was symptom relief during follow-up, defined as an Eckardt score ≤3. Secondary outcomes were procedure-related adverse events, the resting lower esophageal sphincter (LES) pressure, clinical reflux complications, and procedure-related parameters. RESULTS All cases received POEM successfully. The mean operation time was 63.7 min (range 22-130 min). No serious complications related to POEM were encountered. During a mean follow-up period of 30.0 months (range 24-44 months), treatment success was achieved e in 96.8% of cases (mean score pre- vs. post-treatment 7.8 vs. 1.4; P < 0.001). Mean LES pressure also decreased from a mean of 37.9 to 12.9 mmHg after POEM (P < 0.001). One patient experienced only partial symptom relief and additional balloon dilations were carried out to relief the symptoms twice. The overall clinical reflux complication rate of POEM for sigmoid-type achalasia was 25.8%. CONCLUSION The 2-year outcomes of POEM for advanced achalasia with sigmoid-shaped esophagus were excellent, resulting in long-term symptom relief in over 96% cases and without serious complications. The morphological changes of esophagus may make subsequent endoscopic tunneling more challenging and time-consuming, but do not prevent successful POEM.

Abstract
High-resolution manometry (HRM) with 36 pressure transducers spanning the esophagus has revolutionized the diagnosis and treatment of esophageal motility disorders, especially with respect to achalasia. The three major contributions of HRM are as follows: (a) Integrated relaxation pressure (IRP) at the esophagus gastric junction (EGJ) >15 mmHg has a sensitivity of 97 % for the diagnosis of achalasia; (b) there are three distinct subtypes of achalasia - type 1 (no distal pressurization), type II (panesophageal pressurization), and type III (spastic contractions); and (c) subtypes predict the success of treatment with type II patients doing the best and type III being the most difficult to treat. Recent studies also suggest that HRM is superior to conventional manometry for diagnosis of achalasia. Other useful observation from HRM is the recognition of EGJ outflow obstruction (type IV achalasia) with normal peristalsis which may be due to mechanical or functional impairment at the EGJ. Finally, after successful treatment of achalasia, the IRP falls to less than 15 mmHg and the achalasia pressurization pattern resolves sometimes with the return of weak peristalsis. This complements well with the information obtained by the timed barium esophagram.

Abstract
BACKGROUND Three variants of Achalasia have been described using high-resolution esophageal manometry (HRM). While manometrically distinct, their clinical significance has yet to be established. Our objective was to compare the outcome after myotomy in patients with these Achalasia subtypes. METHODS A retrospective chart review was performed to identify patients with Achalasia who had HRM and who underwent Heller myotomy or Per oral endoscopic myotomy (POEM). Symptoms and esophageal clearance by timed barium study were compared before and after treatment. RESULTS We identified 49 patients, 21 males and 28 females, with a median age of 52 years. The primary symptom in all patients was dysphagia, with a median duration of 4 years (range 4 months-50 years). By HRM, ten patients (20 %) were classified as Type I, 30 (61 %) as Type II, and 9 (18 %) as Type III. At a median follow-up of 16 months after myotomy (range 1-63 months), the median Eckardt score was zero and was similar across subtypes. Relief of dysphagia was also similar across subtypes (80 % of Type I, 93 % of Type II and 89 % of Type III). On pre-treatment timed barium study, no patient had complete emptying at 1 or 5 min. After myotomy, complete emptying occurred within 1 min in 50 % (20/40) and within 5 min in 60 % (24/40) and was similar across groups. CONCLUSION Myotomy for Achalasia results in excellent symptomatic outcome and improvement in esophageal clearance. There was no difference among the described HRM Achalasia variants. This calls into question the clinical utility of Achalasia sub-classification and affirms the benefit of myotomy for this disease.

Abstract
INTRODUCTION Traditional treatment for the esophageal motility disorder, achalasia, ranges from endoscopic botulinum toxin (Botox) injections or balloon dilatation, to laparoscopic or open surgical myotomy. Recent advances in endoscopic therapy have led to peroral endoscopic myotomy (POEM) as a viable alternative to traditional techniques for myotomy. Uncertainty exists as to whether the procedure is feasible for patients who have already received prior endoscopic or surgical procedures for therapy, as these groups experience higher failure rates as well as intraoperative mucosal perforations and technical difficulty during Heller myotomy. We describe our first 40 patients who have undergone POEM and compare outcomes between patients who have or have not received previous treatment for achalasia. METHODS AND PROCEDURES We evaluated our prospectively collected database of POEM procedures performed by two surgeons (JLP and JMM) at a single institution. Perioperative data was collected for operative and hospital outcomes. Patients completed pre- and postoperative GERD-Health-Related Quality of Life Questionnaires (GERD-HRQL) and SF-12 surveys for symptom scoring. RESULTS Forty patients received a POEM procedure between 2011 and 2013. Of these, 40% (n = 16) had had at least one prior endoscopic or surgical procedure. Nine had prior Botox injections, 7 had balloon dilations, 3 had both Botox and dilations, and 3 received prior laparoscopic Heller myotomy (two with Dor fundoplication). Mean operative time was 102 min for patients with prior procedures (Prior Tx) and 118 min for patients without any prior procedure (No Tx) (p = 0.07). Intraoperative complication rates for the Prior Tx group were 12.5 versus 16.7% for the No Tx group. Mean follow-up was 10 months. Both groups independently demonstrated clinical improvement in both the GERD-HRQL and SF-12 scores following POEM. There were no statistical differences between the two groups for GERD-HRQL reflux and dysphagia subset scores, or SF-12 mental component summary. CONCLUSION We found favorable outcomes following POEM in patients who have had prior endoscopic or surgical treatments for achalasia, as well as for patients without prior intervention. There were no significant differences between these two groups with regards to operative times, GERD-HRQL scores, and mental component SF-12 scores. One complication requiring intervention occurred in a patient that had received multiple prior Botox injections and balloon dilatations. POEM appears to be a viable alternative for treatment of achalasia compared to traditional techniques, however, long-term data are needed to establish the durability of this technique and to determine whether symptoms will recur necessitating re-intervention.

Abstract
OBJECTIVES Achalasia is an oesophageal disorder characterized by abnormalities of peristalsis and impaired swallowing-induced relaxation. The therapeutic approach at present remains palliative. Peroral endoscopic myotomy (POEM) is thought to be less invasive and to maintain the function of the lower oesophageal sphincter postoperatively. However, the effects of POEM still need to be evaluated and understood. METHODS We analysed the outcome for 45 achalasia patients who underwent POEM in our centre, described the details of surgery and evaluated the effects by 4 s integrated relaxation pressure (4s-IRP). All patients were followed up for at least 2 years and were assessed by the dysphagia score, the Eckardt score, oesophageal manometry and the gastro-oesophageal reflux disease (GERD) Q-questionnaire. According to the new Chicago classification of oesophageal motility using high-resolution manometry, the patients were diagnosed and classified into types I, II and III. RESULTS The average age of the patients was 46.32 ± 19.04 years (range 26-72 years), and the ratio of women to men was 1.81. All patients were suffering from dysphagia; more than half of them experienced regurgitation. The data revealed that POEM considerably reduced the 4s-IRP, dysphagia score and Eckardt score postoperatively (all P < 0.05). The patients with type III achalasia had higher values of 4s-IRP than the others (type I, P = 0.025; type II, P = 0.022) before treatment and at 3 months after treatment (type I, P = 0.028; type II, P = 0.047). In type I patients, GERD symptoms were more likely to appear at 24 months after POEM than in type II and III patients (P = 0.001 and P < 0.001, respectively). CONCLUSIONS Peroral endoscopic myotomy provides definite relief of symptoms in these patients with achalasia and offers them long-term therapeutic benefit. Considering the risks of surgery, we believe that POEM is a better choice than surgery for achalasia patients and carries lower risk. However, our study is a preliminary exploration; therefore, larger-scale studies are needed for further research on POEM.

Abstract
Treatment options for achalasia include oral pharmacologic therapy, endoscopic injection of botulinum toxin, pneumatic dilation, and myotomy (conventionally by laparoscopy, but more recently by an endoscopic approach). Oral pharmacologic agents have fallen out of use because of insufficient efficacy and frequent side effects. Endoscopic injection of botulinum toxin is safe and has good short-term effectiveness, but as the effect invariably wears off after a few months, this treatment is reserved for patients who are not candidates for more definitive treatments. Pneumatic dilation and surgical myotomy are currently considered the most effective treatments, with similar effectiveness in randomized controlled trials with follow-up of up to 2 years. The risk/benefit ratio and choice of therapy depend on patient characteristics (age, comorbidities, disease stage, prior treatments), patient's preference, and locally available expertise. Treatment of patients who fail or relapse after initial therapy is challenging and the success rate of pneumatic dilation or myotomy in this group is lower compared with previously untreated patients. The recently developed peroral endoscopic approach to myotomy has achieved excellent results in early uncontrolled studies, but high-quality randomized trials are needed to ensure widespread adoption is reasonable. Finally, retrospective data suggest that achalasia subtypes as defined by high-resolution esophageal pressure topography may guide treatment choice, but confirmation in prospective outcome studies is awaited.

Abstract
AIM: To investigate the diagnostic criteria for esophageal achalasia and evaluate the clinical effects of peroral endoscopic myotomy (POEM) in the treatment of esophageal achalasia.
METHODS: The clinical date of 12 patients who were diagnosed with esophageal achalasia and recived POEM in the Ningbo Medical Center, Lihuili Hostpial between November 2012 and January 2014 were reviewed retrospectively. The surgical results, parameters measured by esophageal manometry before and after POEM, and complications after POEM and during follow-up were analyzed.
RESULTS: POEM were successful in 10 of the 12 patients. There were 1 case of subcutaneous emphysema, 1 case of pneumomediastinum, subcutaneous emphysema and pleural effusion, and 1 case of hemorrhage of the digestive tract. Symptoms were significantly improved in 10 patients who had successful POEM; parameters measured by esophageal manometry were also improved obviously.
CONCLUSION: Esophageal manometry is the gold standard for the diagnosis of achalasia. POEM has appreciable short-term effects in the treatment of achalasia, but the long-term efficacy and complications need further follow-up observations.

Abstract
BACKGROUND The optimal anti-reflux procedure after Heller cardiomyotomy for oesophageal achalasia remains unclear. The most commonly used procedure is the anterior partial fundoplication according to Dor, although during recent years the posterior counterpart (Toupet) has become popular. METHODS Patients with newly diagnosed achalasia and referred for cardiomyotomy were randomised to receive either an anterior or partial posterior fundoplication following a classical cardiomyotomy. The effect of surgery was assessed during the first postoperative year by Eckardt scores, EORTC QLQ-OES18 scores and HRQL questionnaires. Timed barium oesophagogram (TBO) and ambulatory 24-h pH monitoring were performed to determine oesophageal emptying and the degree of reflux control, respectively. RESULTS Forty-two patients were randomised into Dor (n = 20) and Toupet (n = 22) groups. Eckardt scores improved dramatically with both procedures, but the EORTC QLQ-OES18 (functional scales) scores revealed significantly better relative improvements in the Toupet group compared to the Dor repair (P = 0.044). Corresponding advantages in favour of Toupet were observed postoperatively in the percentage of oesophageal emptying at TBO (P = 0.011 in height and P = 0.018 in area), an effect not observed in the Dor group. There were no other significant differences recorded between the study groups concerning HRQL evaluations and objective assessment of gastro-oesophageal acid reflux. CONCLUSIONS A partial posterior fundoplication after cardiomyotomy seems to achieve more improvement in oesophageal emptying and EORTC QLQ-OES18 functional scale scores than the anterior fundoplication. Otherwise no differences between the two anti-reflux repairs were noted. TRIAL REGISTRATION NUMBER ClinicalTrials.gov Identifier: NCT01933373.

[PMID: 24710506 PMCID: PMC4307753 DOI: 10.1038/ajg.2014.61] [Citation(s) in RCA: 45] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/15/2014] [Accepted: 03/13/2014] [Indexed: 12/11/2022]
Abstract
OBJECTIVES The aim of this study was to assess whether high-resolution impedance manometry (HRIM) could be used to assess bolus retention similar to the timed barium esophagram (TBE). METHODS Twenty achalasia patients (10 males, aged 21-79 years) were prospectively evaluated with HRIM and TBE to determine the correlation between barium column height and the impedance bolus height (IBH). The TBE protocol used a 200-ml barium challenge and the HRIM protocol used a 200-ml saline challenge protocol. Both protocols were performed in an upright position and the heights of the barium and impedance columns were measured at 1 and 5 min. Analysis of IBH was performed with a topographic technique and a spatial impedance variation plot. RESULTS There was no significant difference between the median IBH and barium column at 1 min (IBH: 12.0 cm (interquartile range (IQR), 8.0-18.0); TBE: 12.0 cm (IQR, 7.0-19.0); P=0.90) or at 5 min (IBH: 11.0 cm (IQR, 1.0-17.0); TBE: 9.0 cm (IQR, 4.0-12.0); P=0.47). In addition, the correlation between the two measurements at 1 and 5 min was 0.60 and 0.86, respectively. Using a barium column or impedance height of >5.0 as a definition of bolus retention was associated with 75% concordance at 1 min and 95% concordance at 5 min. CONCLUSIONS There was excellent agreement between TBE and high-resolution impedance manometry (HRIM) for assessing bolus retention at 5 min. Thus, HRM with impedance may be used as a single test to assess bolus retention and motor function in the management of achalasia.

Abstract
BACKGROUND We report our short-term experience with peroral endoscopic myotomy (POEM) and compare perioperative outcomes with laparoscopic Heller myotomy (LHM) for achalasia. METHODS Patients from an institutional review board-approved protocol underwent POEM and were followed prospectively. Comparisons were made, in a prospective esophageal database, with patients who underwent LHM over the same period. RESULTS We studied 18 patients who underwent POEM and compared them to 21 who underwent LHM. Demographics, preoperative Eckardt scores, motility data, and prior intervention history were comparable. Operative time, myotomy length, and complication rates (1 perforation in each group) were equal. Postoperative pain was significantly different by visual analogue score (POEM 3.9 ± 0.6 versus LHM 5.7 ± 0.4, P = .02) and analgesic use (POEM 26.0 ± 13.7 versus LHM 90.0 ± 48.5 mg morphine, P = .02). Return to activities of daily living was significantly faster in the POEM group (2.2 ± 0.6 vs 6.4 ± 1.0 days, P = .03). Postoperative dysphagia and Eckardt scores were equally successful in both groups. CONCLUSION POEM results in similar relief of dysphagia with less postoperative pain and quicker return to normal activities.

Abstract
AIM: To evaluate the clinical efficacy of peroral endoscopic myotomy (POEM) in the treatment of achalasia cardia (AC).
METHODS: The clinical data for 7 patients who were diagnosed with AC and received POEM at our center from May 16, 2011 to May 30, 2013 were reviewed. They ranged in age from 20 to 48 years old, with a mean value of 30.4 years. The disease courses lasted for 2 to 15 years. Key procedures of POEM were esophageal mucosal incision, submucosal tunneling by endoscopic submucosal dissection, endoscopic myotomy of the circular muscle and closure of mucosal entry using hemostatic clips.
RESULTS: POEM was successful in all the patients. Mean operation time was 114 min (range, 55-180 min). Mean submucosal tunneling length was 11.7 cm (range, 10-13 cm). Mean length of endoscopic myotomy of the circular muscle was 9.2 cm (range, 8-11 cm). Two cases underwent full-thickness myotomy. Patients were followed for one year. Five cases of dysphagia were cured, and no obvious effect was observed in two cases.
CONCLUSION: POEM has good short-term efficacy in relieving dysphagia. Further observation is needed to evaluate long-term efficacy and complications.
