Abstract
BACKGROUND Repeat per-oral endoscopic myotomy is occasionally performed for persistent/recurrent symptoms in patients with achalasia, and yields favorable outcomes. We investigated a novel technique, per-oral endoscopic dual myotomy (dual-POEM), where a second myotomy was performed during a single session to augment the efficacy and avoid repeat interventions. The aim of this study was to evaluate its feasibility, safety and efficacy. METHODS Consecutive patients diagnosed with achalasia who underwent dual-POEM (1/2018-5/2019) were prospectively collected and retrospectively analyzed. Patients with baseline Eckardt score ≥ 9, ≥ 10 years of symptoms, and/or having prior interventions other than myotomy received dual-POEM. The primary outcome was clinical success (Eckardt score ≤ 3). Secondary outcomes were procedure-related adverse events, change in lower esophageal sphincter (LES) pressure, and reflux complications. RESULTS Seventeen patients received dual-POEM. Procedure-related adverse events were observed in 2 (11.8%) patients (mucosal injury and pneumonitis). Both were minor in severity. During a median follow-up of 33 months (interquartile range, IQR [31,35]; range, 19-36), clinical success was achieved in 16 (94.1%) patients. The median Eckardt score decreased from 9 (IQR [8, 11.5]; range 7-12) to 1 (IQR [1, 2]; range 0-4) (P < 0.001), and LES pressure decreased from 25.8 mmHg (IQR [21.7, 33.5]; range 17.7-46.3) to 7.4 mmHg (IQR [6.3, 10.4]; range 2.2-12.6) (P < 0.001). Seven (41.2%) patients developed postprocedural reflux either by gastroesophageal reflux disease questionnaire or esophagitis endoscopically, all successfully treated with proton pump inhibitors. CONCLUSION Dual-POEM preliminarily demonstrated high efficacy with a favorable safety profile in patients with achalasia with predictors of treatment failure.

Comparison of preoperative, intraoperative, and follow-up functional luminal imaging probe measurements in patients undergoing myotomy for achalasia. Gastrointest Endosc 2021; 94:509-514. [PMID: 33662363 PMCID: PMC8380635 DOI: 10.1016/j.gie.2021.02.031] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/07/2020] [Accepted: 02/19/2021] [Indexed: 02/08/2023]
Abstract
BACKGROUND AND AIMS The functional luminal imaging probe (FLIP) is a novel catheter-based device that measures esophagogastric junction (EGJ) distensibility index (DI) in real time. Previous studies have demonstrated DI to be a predictor of post-treatment clinical outcomes in patients with achalasia. We sought to evaluate EGJ DI in patients with achalasia before, during, and after peroral endoscopic myotomy (POEM) and laparoscopic Heller myotomy (LHM) and to assess the correlation of DI with postoperative outcomes. METHODS DI (defined as the minimum cross-sectional area at the EGJ divided by distensive pressure) was measured at 4 time points in patients undergoing surgical myotomy for achalasia: (1) during outpatient preoperative endoscopy (preoperative DI), (2) at the start of each operation after the induction of anesthesia (induction DI), (3) at the conclusion of each operation (postmyotomy DI), and (4) at routine follow-up endoscopy 12 months postoperatively (follow-up DI). Routine Eckardt symptom score, endoscopy, timed barium esophagram, and pH study were obtained 12 months postoperatively. RESULTS Forty-six patients (35 POEM, 11 LHM) underwent FLIP measurements at all 4 time points. Preoperative and induction mean DI were similar for both groups (POEM, 1 vs .9 mm2/mm Hg; LHM, 1.7 vs 1.5 mm2/mm Hg). POEM resulted in a significant increase in DI (induction .9 vs postmyotomy 7 mm2/mm Hg, P < .001). There was a subsequent decrease in DI in the follow-up period (postmyotomy 7 vs follow-up 4.8 mm2/mm Hg, P < .01), but DI at follow-up was still significantly improved from preoperative values (P < .001). For LHM patients, DI also increased as a result of surgery (induction 1.5 vs postmyotomy 5.9 mm2/mm Hg, P < .001); however, the increase was smaller than in POEM patients (DI increase 4.4 vs 6.2 mm2/mm Hg, P < .05). After LHM, DI also decreased in the follow-up period, but this change was not statistically significant (5.9 vs 4.4 mm2/mm Hg, P = .29). LHM patients with erosive esophagitis on follow-up endoscopy had a significantly higher postmyotomy DI compared with those without esophagitis (9.3 vs 4.8 mm2/mm Hg, P < .05). CONCLUSIONS EGJ DI improved dramatically as a result of both POEM and LHM, with POEM resulting in a larger increase. Mean DI decreased at intermediate follow-up but remained well above previously established thresholds for symptom recurrence. DI at the conclusion of LHM was predictive of erosive esophagitis in the postoperative period, which supports the potential use of FLIP for calibration of partial fundoplication construction during LHM.

Abstract
Achalasia is a rare neurodegenerative disorder causing dysphagia and is characterized by abnormal esophageal motor function as well as the loss of lower esophageal sphincter (LES) relaxation. The assessment and management of achalasia has significantly progressed in recent years due to the advances in high-resolution manometry (HRM) technology along with the improvements and innovations of therapeutic endoscopy procedures. The recent evolution of HRM technology with the inclusion of an adjunctive test, fluoroscopy, and EndoFLIP has enabled more precise diagnoses of achalasia to be made and the subgrouping into therapeutically meaningful subtypes. Current management possibilities include endoscopic treatments such as Botulinum toxin injected to the LES and pneumatic balloon dilation. Surgical treatment includes laparoscopic Heller myotomy and esophagectomy. Furthermore, in recent years, per oral endoscopic myotomy (POEM) has established itself as a principal endoscopic therapeutic alternative to the traditional laparoscopic Heller myotomy. The latest randomized trials report that POEM, pneumatic balloon dilatation, and laparoscopic Heller's myotomy have comparable effectiveness and complications rates. The aim of the current review is to provide a practical clinical approach to dysphagia and to shed light on the most recent improvements in diagnostics and treatment of achalasia over the last two years.

Abstract
Background/Aims Achalasia is a rare disease, but the incidence is increasing recently. Peroral esophageal myotomy (POEM) is an effective treatment. Regurgitation is a common symptom before and after POEM. Our aim is to investigate the factors related to preoperative and postoperative reflux symptoms. Methods Our study was retrospective. The achalasia patients diagnosed by high-resolution manometry and gastroscopy were divided into reflux group and non-reflux group before and after POEM, respectively. General information, symptoms, POEM information, and manometric results were compared. Results (1) Ninety-six of 130 patients had reflux symptoms before POEM. The lower esophageal sphincter pressure (LESP) in the reflux group was significantly higher than the non-reflux group (P = 0.023), while integrated relaxation pressure (IRP) was similar. The reflux group had longer esophagus than the non-reflux group (P = 0.006). Reflux symptoms were not related to subtypes of achalasia. (2) Twenty-five of 84 patients had reflux symptoms after POEM. Postoperative Eckardt scores, LESP, and 4-second IRP (4sIRP) were significantly lower than the preoperative values (P < 0.001). The preoperative values and POEM information were similar between the postoperative 2 groups and there was no significant difference in the presence of preoperative reflux symptoms between 2 groups. The postoperative LESP and 4sIRP were similar between the 2 groups, however, the postoperative UESP was significantly higher in the reflux group than the non-reflux group (P = 0.042). The non-reflux group had more declines in Eckardt scores and LESP than the reflux group. Conclusions The reflux symptoms of achalasia patients without treatment were mainly due to food retention. The postoperative reflux symptoms were not the sign of the excessive relaxation of lower esophageal sphincter.

Abstract
BACKGROUND It is common knowledge that esophageal achalasia patients have a high risk of developing esophageal carcinoma. The present study assessed the characteristics of esophageal carcinoma patients following laparoscopic Heller-Dor surgery (LHD) for esophageal achalasia. METHOD Among 622 cases which were esophageal achalasia patients and underwent LHD as the primary surgery, we compared the patient background, pathophysiology, symptoms, and surgical outcomes according to whether or not esophageal carcinoma occurred following surgery. RESULTS Six cases (0.96%) of postoperative esophageal carcinoma were confirmed. The characteristics of the cases in which esophageal carcinoma occurred were older age, longer disease duration (p = 0.0362 and 0.0028, respectively), decreased sphincter pressure of the lower esophagus, a high rate of sigmoid esophagus, and a long esophagus lateral diameter (p = 0.0214, 0.001, and 0.0416, respectively). Moreover, no differences in surgical outcomes were confirmed and there were no differences in symptoms from before and following surgery. CONCLUSION The characteristics of esophageal carcinoma patients with achalasia following laparoscopic myotomy were an older age, longer disease duration, and greater progression of disease pathophysiology.

Abstract
Pseudoachalasia accounts for up to 4% of patients who present with achalasia-like picture and most often relates to occult malignancy at the cardia or gastroesophageal junction. Thus, any delay in diagnosis might lead to more advanced disease and less chance for curative therapy, not to mention the risk of serious complications resulting from the treatment of supposed achalasia instead of the true underlying cause. The entity should be suspected in patients with advanced age of onset, a shorter duration of symptoms, profound weight loss and difficulty in passing the gastroesophageal junction on endoscopy. The diagnosis of pseudoachalasia can be challenging as upper endoscopy with biopsy might be false negative in 25% of cases and lesions cannot always be detected on computerized tomography scan. Endoscopic ultrasound and guided biopsy play an increasingly important role in the workup of this condition. Treatment of pseudoachalasia depends on the underlying cause. The aim of this review is to highlight the clinicopathological features that distinguish pseudoachalasia from achalasia and the most appropriate diagnostic workup as well as the subsequent management for this condition.

Abstract
BACKGROUND AND AIM Achalasia patients usually present lower esophageal sphincter thickening, which can impact the expansibility of cardia. We aimed to investigate the effect of cardiac muscularis propria (MP) on perioperative adverse events (AEs) and treatment outcomes of patients treated with peroral endoscopic myotomy (POEM). METHODS We retrospectively reviewed 114 patients with achalasia undergoing pre-POEM endoscopic ultrasonography (EUS) between May 2013 and November 2019. Cardiac MP thickness was measured using EUS. POEM failure was defined as Eckardt score >3. Risk factors for perioperative AEs and POEM failure were identified. RESULTS Patients were divided into the thin (n = 52) and the thick group (n = 62) based on the median of cardiac MP thickness (3.0 mm). Perioperative AEs rate of the thin group seemed to be slightly higher than that of the thick group (11.5% vs. 4.8%, P = 0.30). During a median follow-up of 30 months (range 1-77), 100 patients completed follow-up, 16 (16%) of which occurred clinical failure. The clinical outcomes of patients in the thin group were significantly poorer than those patients in the thick group (P = 0.006). Cardiac MP thickness was an independent risk factor for POEM failure (hazard ratio 3.9, P = 0.02; Cox regression), but not the risk factor for perioperative AEs (odds ratio 2.6, P = 0.2; logistic regression). CONCLUSION Cardiac MP thickness could be a novel predictive factor for POEM failure in patients with achalasia.

Abstract
Background and study aims Peroral endoscopic myotomy (POEM) is increasingly being used as the preferred treatment option for achalasia. The aim of this systematic review and meta-analysis was to compare the efficacy and safety of POEM versus pneumatic balloon dilation (PD). Methods We performed a comprehensive review of studies that reported clinical outcomes of POEM and PD for the treatment of achalasia. Measured outcomes included clinical success (improvement of symptoms based on a validated scale including an Eckardt score ≤ 3), adverse events, and post-treatment gastroesophageal reflux disease (GERD). Results Sixty-six studies (6268 patients) were included in the final analysis, of which 29 studies (2919 patients) reported on POEM and 33 studies (3050 patients) reported on PD and 4 studies (299 patients) compared POEM versus PD. Clinical success with POEM was superior to PD at 12, 24, and 36 months (92.9 %, vs 76.9 % P = 0.001; 90.6 % vs 74.8 %, P = 0.004; 88.4 % vs 72.2 %, P = 0.006, respectively). POEM was superior to PD in type I, II and III achalasia (92.7 % vs 61 %, P = 0.01; 92.3 % vs 80.3 %, P = 0.01; 92.3 %v 41.9 %, P = 0.01 respectively) Pooled OR of clinical success at 12 and 24 months were significantly higher with POEM (8.97; P = 0.001 & 5.64; P = 0.006). Pooled OR of GERD was significantly higher with POEM (by symptoms: 2.95, P = 0.02 and by endoscopic findings: 6.98, P = 0.001). Rates of esophageal perforation (0.3 % vs 0.6 %, P = 0.8) and significant bleeding (0.4 % vs 0.7 %, P = 0.56) were comparable between POEM and PD groups. Conclusions POEM is more efficacious than PD in the treatment of patients with achalasia during short-term and long-term follow-up, albeit with higher risk of abnormal esophageal acid exposure.

Abstract
Peroral endoscopic myotomy (POEM) is a novel minimally invasive intervention, which has shown to be effective and safe for treating achalasia in adults. Presently, POEM was also reported to be effective for achalasia in children. So we conducted this study to explore the clinical outcomes of POEM for pediatric achalasia. A systematic literature search in PubMed, Embase, and Cochrane databases was performed, which covered the period from January 2009 to June 2020. Selecting studies and collecting data was independently by two reviewers according to predefined criteria. The statistical analysis was carried out using Comprehensive Meta-Analysis software version 2 and Review Manager 5.3. A total of 11 studies with 389 children were identified in the final analysis. Pooled technical success of POEM treatment achalasia was achieved in 385 children (97.4%; 95% confidence interval [CI], 94.7%-98.7%), and the pooled clinical success was achieved in 348 children (92.4%; 95% CI, 89.0%-94.8%). After POEM, the Eckardt score was significantly decreased by 6.76 points (95% CI, 6.18-7.34, P < 0.00001), and the lower esophageal sphincter pressure was significantly reduced by 19.38 mmHg (95% CI, 17.54-21.22, P < 0.00001). The pooled major adverse events rate related to POEM was 12.8% (95% CI, 4.5%-31.5%) and the gastroesophageal reflux rate was 17.8% (95% CI, 14.2%-22.0%). Our current study demonstrated that the POEM was an effective and safe technique for treating achalasia in children. Further randomized comparative studies of POEM and other therapeutic methods are warranted to determine the most effective treatment modality for achalasia in children.

BACKGROUND Achalasia has been reported to be associated with esophageal cancers (ECs). However, owing to the rarity of achalasia, details of achalasia-related ECs are not well investigated. METHOD The incidence of ECs in Japanese patients with achalasia and achalasia-related esophageal motility disorders (EMDs) was estimated, and risk factors for achalasia-related ECs were determined. Characteristics of ECs and treatment courses were also analyzed. RESULTS Between 2010 and 2019, 2714 Japanese patients with achalasia and achalasia-related EMDs were recorded in 7 high-volume centers; 24 patients (21 men, 3 women) developed ECs. The incidence of ECs was estimated at 0.078 and 0.28 per 100 person-years from the onset and the diagnosis of disease, respectively. Kaplan-Meier estimate suggested that, in addition to a long history of achalasia, advanced age, male sex, and regular alcohol consumption were statistically significant risk factors for EC development. A prevalence of 40 ECs (12.5% multiple lesions, and 22.7% metachronal lesions) was also noted, predominantly distributed over the thoracic esophagus. All were histologically diagnosed as squamous cell carcinoma. Superficial ECs were successfully treated with endoscopic treatment in all cases, except one. Achalasia-related Barret esophagus was extremely rare, and Barret adenocarcinoma was not detected in our cohort. CONCLUSION The high relative risk of ECs was clarified in Japanese achalasia patients, although the absolute risk remained low. Therefore, surveillance endoscopy may be recommended in limited patients with several aforementioned risk factors determined. Superficial cancer can be treated with endoscopic treatment. Multiple and metachronal ECs should be screened.

Abstract
Idiopathic achalasia is an esophageal motor disorder characterized by the loss of the lower esophageal sphincter ganglion, resulting in impaired lower esophageal relaxation and absence of esophageal peristalsis. Patients commonly present with progressive dysphagia accompanied by reflux, heartburn, retrosternal pain, and severe weight loss. Diagnosis is primarily based on the patient's chief complaints, barium esophagography, and the most recent high-resolution manometry. Endoscopic assessment and endoscopic ultrasonography also have significant value with regard to the exclusion of esophageal anatomical lesions, neoplastic diseases, and pseudoachalasia. However, as most patients with achalasia demonstrate a gradual onset, early diagnosis is difficult. Currently, treatment of idiopathic achalasia, including pneumatic dilation, stent placement, and surgical myotomy, is aimed at reducing lower esophageal sphincter pressure and relieving the symptoms of dysphagia. Peroral endoscopic myotomy has gradually become the mainstream treatment because it causes less trauma and has a rapid recovery rate. This article reviews the main methods of diagnosis and treatment of achalasia, with an emphasis on the potential of peroral endoscopic myotomy and the advancements of immunotherapy for achalasia.

Abstract
BACKGROUND Peroral endoscopic myotomy (POEM) is a particularly attractive intervention for achalasia. Presently, POEM has been reported to be effective and safe for achalasia in geriatric patients. Herein, this systematic review was conducted to explore the role of POEM in geriatric patients with achalasia. METHOD PubMed, Embase, and Cochrane Library were searched to identify studies evaluating the clinical outcome of POEM in geriatric patients with achalasia during January 2009 to October 2020. The primary outcomes were technical and clinical success. Secondary outcomes included postoperative Eckardt score, lower esophageal sphincter (LES) pressure, adverse events, and clinical reflux. RESULTS There were 7 studies with a total of 469 geriatric patients, and the pooled technical success of POEM treatment was 98.1% (95% confidence interval [CI], 95.1-99.3%), and the pooled clinical success was 92.5% (95% CI, 89.3-94.8%). After POEM, the Eckardt score significantly decreased by 6.09 points (95% CI, 5.44-6.74, p < 0.00001), and the LES pressure significantly reduced by 13.53 mm Hg (95% CI, 5.14-21.91, p = 0.002). The pooled adverse events rate was 9.0% (95% CI, 4.3-17.9%), and the post-POEM clinical reflux rate was 17.4% (95% CI, 12.9-23.2%). CONCLUSION Our current study demonstrated that POEM was an effective and safe technique for achalasia in geriatric patients.

Abstract
INTRODUCTION Achalasia is a debilitating primary esophageal motility disorder. Heller myotomy (HM) is a first-line therapy for the treatment of achalasia patients who have failed other modalities. Other indications for HM include diverticulum, diffuse esophageal spasm, and esophageal strictures. However, long-term outcomes of HM are unclear. This study aims to assess incidence of reintervention, either endoscopically or through minimally invasive or resectional procedures, in patients who underwent HM in New York State. METHODS The Statewide Planning and Research Cooperative System (SPARCS) administrative longitudinal database identified 1817 adult patients who underwent HM between 2000 and 2008 for achalasia, esophageal diverticulum, diffuse esophageal spasm, and esophageal strictures, based on ICD-9 and CPT codes. Through the use of unique identifiers, patients requiring reintervention were tracked up to 2016 (for at least 8 years follow-up). Primary outcome was incidence of subsequent procedures following HM. Secondary outcomes were time to reintervention and risk factors for reintervention. RESULTS Of the 1817 patients who underwent HM, 320 (17.6%) required subsequent intervention. Of the 320 patients, 234 (73.1%) underwent endoscopic reinterventions, 54 (16.9%) underwent minimally invasive procedures, and 32 (10%) underwent resectional procedures as their initial revisional intervention. Of the 234 patients who underwent endoscopic reintervention as their initial revisional procedure, only 40 (16.8%) required subsequent surgical procedures. Over a mean follow-up of 7.0 years, the mean time to a subsequent procedure was 4.3 ± 3.74 years. Reintervention rates after 10 years following HM for achalasia, diverticulum ,and other indication were 24.4%, 12.6%, and 37%, respectively. CONCLUSION The majority of HM reinterventions were managed solely by endoscopic procedures (60.6%). Heller myotomy remains an excellent procedure to prevent surgical reintervention for achalasia and diverticulum.

Abstract
Peroral endoscopic myotomy (POEM) has been increasingly accepted as the first-line treatment of achalasia. However, laparoscopic Heller myotomy or esophagectomy still remains as the mainstay treatment for advanced achalasia featured with megaesophagus and/or sigmoid-shaped esophagus. Although the efficacy of POEM for advanced achalasia with sigmoid-shaped esophagus has been described, little is known about the role of POEM for patients with megaesophagus. The aim of our study is to evaluate the efficacy and safety of POEM for advanced achalasia with megaesophagus. Patients who received initial examinations and underwent POEM in our hospital from June 2013 to December 2018 were identified and data were retrospectively analyzed. The advanced achalasia was defined as megaesophagus with a diameter of ≥6 cm. The primary outcome was clinical success. The secondary outcomes were technical success and adverse events. A total of 112 patients (50 females, 44.6%) were included with a mean age of 44.8 years. The median symptom duration was 6.5 years (IQR:3.0-13.0 years). Modified POEM techniques were used in 27.7% (31/112) of patients. Technical success rate was 99.1% (112/113) per procedure. Clinical success was seen in 93.1% patients with median Eckardt score decreasing from 8.0 to 1.0 (P < 0.001) during a median 31.0 months of follow-up. The mean LES pressure decreased from 29.5 mmHg to 14.2 mmHg after POEM (P < 0.05). Procedure-related adverse events occurred in 8.9% patients. Reflux disease was observed postoperatively in 26.7% of patients. POEM is also indicated for patients with advanced achalasia with a favorable safety and efficacy.

Abstract
BACKGROUND Achalasia subtypes on high-resolution manometry (HRM) prognosticate treatment response and help direct management plan. We aimed to utilize parameters of distension-induced contractility and pressurization on functional luminal imaging probe (FLIP) panometry and machine learning to predict HRM achalasia subtypes. METHODS One hundred eighty adult patients with treatment-naïve achalasia defined by HRM per Chicago Classification (40 type I, 99 type II, 41 type III achalasia) who underwent FLIP panometry were included: 140 patients were used as the training cohort and 40 patients as the test cohort. FLIP panometry studies performed with 16-cm FLIP assemblies were retrospectively analyzed to assess distensive pressure and distension-induced esophageal contractility. Correlation analysis, single tree, and random forest were adopted to develop classification trees to identify achalasia subtypes. KEY RESULTS Intra-balloon pressure at 60 mL fill volume, and proportions of patients with absent contractile response, repetitive retrograde contractile pattern, occluding contractions, sustained occluding contractions (SOC), contraction-associated pressure changes >10 mm Hg all differed between HRM achalasia subtypes and were used to build the decision tree-based classification model. The model identified spastic (type III) vs non-spastic (types I and II) achalasia with 90% and 78% accuracy in the train and test cohorts, respectively. Achalasia subtypes I, II, and III were identified with 71% and 55% accuracy in the train and test cohorts, respectively. CONCLUSIONS AND INFERENCES Using a supervised machine learning process, a preliminary model was developed that distinguished type III achalasia from non-spastic achalasia with FLIP panometry. Further refinement of the measurements and more experience (data) may improve its ability for clinically relevant application.

Abstract
Dysphagia is difficulty in swallowing that can be caused by a number of disorders that involve either the oropharynx or the esophagus. Specific endoscopic treatment for dysphagia depends on its etiology, whether the dysphagia is caused by mechanical narrowing or a motor disorder. Variable endoscopic treatment strategies can be used to manage dysphagia. Patient with dysfunction of the upper esophageal sphincter may benefit from esophageal dilationor injection of botulinum toxin. Pneumatic balloon dilation, injection of botulinum toxin, peroral endoscopic myotomy can be considered as treatment options for esophageal motility disorders. Endoscopic dilation is the treatment choice of esophageal stricture, while intraluminal steroid injection and temporary stent can be considered in refractory benign esophageal stricture. Self-expandable metal stent insertion can be considered for dysphagia with malignant cause.

Abstract
INTRODUCTION Epidemiological studies assessing relative risk and incidence rate of esophageal cancer in patients with achalasia are scarce. We performed a long-term prospective cohort study to evaluate the risk of both squamous cell carcinoma and adenocarcinoma of the esophagus in these patients. METHODS Between 1973 and 2018, patients with primary achalasia were followed by the same protocol including upper endoscopy with esophageal biopsies. Standardized incidence ratios (SIRs) with 95% confidence interval (CI) were used to estimate the relative risk of esophageal cancer in patients with achalasia compared with the sex- and age-matched general population. RESULTS A cohort of 566 patients with achalasia (46% men, mean age at diagnosis: 48.1 years) was followed for a mean of 15.5 years since the diagnosis of achalasia. Overall, 20 patients (15 men) developed esophageal cancer: 15 squamous cell carcinoma and 5 adenocarcinoma. The risk of esophageal cancer was significantly greater than the general population (SIR 104.2, 95% CI 63.7-161), and this for both squamous cell carcinoma (SIR 126.9, 95% CI 71.0-209.3) and adenocarcinoma (SIR 110.2, 95% CI 35.8-257.2). The excess risk was higher in men than women. Annual incidence rate of esophageal cancer was only 0.24% and was higher for squamous cell carcinoma (0.18%) than adenocarcinoma (0.06%). DISCUSSION Patients with achalasia have an excess risk of developing both squamous cell carcinoma and adenocarcinoma of the esophagus; however, this prospective cohort study confirms that the annual incidence of esophageal cancer is rather low. These findings may have implications for endoscopic surveillance of patients with achalasia.

Abstract
BACKGROUND AND AIMS It is unclear whether the common practice of postoperative day (POD) 1 esophagram impacts clinical care or reliably identifies significant adverse events (AEs) related to peroral endoscopic myotomy (POEM). Therefore, we aimed to correlate the most clinically relevant esophagram findings with postoperative outcomes after POEM. METHODS Patients were retrospectively reviewed and included if they underwent POEM at 1 of the 3 study institutions between 2014 and 2018. Patient outcomes were assessed in relation to relevant POD 1 esophagram findings such as esophageal dissection or leak. RESULTS One hundred seventy post-POEM contrast esophagrams (139 fluoroscopy-based vs 31 CT-based) performed on POD 1 were included. Most esophagrams (n = 98) contained abnormal findings but only 5 showed esophageal leak or dissection. Confirmed postoperative AEs of leak or dissection occurred in 4 patients. In 2 patients, POD 1 esophagram appropriately identified the leak or dissection, but in the other 2 patients the initial esophagram was negative, and the AEs were not recognized before clinical deterioration. One patient had a false-positive leak and dissection noted on esophagram leading to an unremarkable endoscopy. CONCLUSIONS Despite the low AE rate after POEM, follow-up esophagram on POD 1 frequently shows expected, unremarkable postprocedural findings and occasionally fails to diagnose serious AEs. This results in pitfalls in accuracy regarding agreement between esophagram versus clinical and endoscopic findings. Relying exclusively on esophagram for post-POEM clinical decision-making can lead to unnecessary additional testing or missed AEs.

Abstract
OBJECTIVES This study compared the safety and efficacy of peroral endoscopic myotomy for esophageal motility disorders between octogenarians and non-octogenarians. METHODS This retrospective observational study recruited 321 patients (28 octogenarians and 293 non-octogenarians) who underwent peroral endoscopic myotomy from two institutions. Clinical success (postoperative Eckardt score ≤ 3), technical success (completion of gastric and esophageal myotomy), and perioperative adverse events were compared between octogenarians and non-octogenarians. Perioperative adverse events were classified into major and minor adverse events based on the International Peroral Endoscopic Myotomy Survey criteria and were subdivided into technical and non-technical adverse events according to the presence of a direct causal relationship with the procedure. RESULTS There were no significant differences in the rates of clinical success 1 year after treatment (100% vs. 97.3%, P = 0.64) and technical success (100% vs. 99.7%, P = 0.91) between octogenarians and non-octogenarians. Octogenarians had a higher incidence of perioperative adverse events (28.6% vs. 10.2%, P = 0.00097), particularly major adverse events (25.0% vs. 3.0%, P < 0.0001). There were no significant differences in the incidence of minor adverse events (7.1% vs. 7.9%, P = 0.67). Although there was no difference in the incidence of technical adverse events (10.7% vs. 9.2%, P = 0.74), octogenarians had a significantly higher incidence of non-technical adverse events (17.9% vs. 1.0%, P = 0.0002). CONCLUSIONS There were no significant differences in short-term clinical success and technical success between octogenarians and non-octogenarians. However, octogenarians showed a significantly higher incidence of perioperative adverse events, particularly in major adverse events and non-technical adverse events. Peroral endoscopic myotomy for octogenarians should be carefully applied.

Abstract
AbstractBRICS (Brazil, Russia, India, China, and South Africa) countries account for more than two-thirds of the global tuberculosis burden. Tuberculosis is a common diagnosis in patients presenting with chronic respiratory symptoms in these high-burden countries, which results in other diseases being missed easily. The national tuberculosis elimination program encourages to start antitubercular treatment on a clinical basis even without any confirmatory evidence. This has resulted in missing many nontuberculosis cases and unnecessarily exposing to adverse effects of antitubercular drugs. Here we report one such instance where achalasia cardia was missed for a long time.

Peroral endoscopic myotomy for patients with achalasia with previous Heller myotomy: a systematic review and meta-analysis. Gastrointest Endosc 2021; 93:47-56.e5. [PMID: 32522483 DOI: 10.1016/j.gie.2020.05.056] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/14/2019] [Accepted: 05/17/2020] [Indexed: 12/11/2022]
Abstract
BACKGROUND AND AIMS Heller myotomy (HM) is considered the standard surgical treatment for patients with achalasia. However, approximately 10% to 20% of patients with achalasia have persistent or recurrent symptoms after HM that require further therapy. Several studies have reported the outcomes of peroral endoscopic myotomy (POEM) in these patients. We performed a systematic review and meta-analysis to evaluate the efficacy and safety of POEM in patients with achalasia with previous HM. METHODS An electronic literature search of PubMed, Embase, and the Cochrane Library was conducted up to January 31, 2020. Studies evaluating the outcomes of POEM in patients with achalasia with previous HM were eligible for inclusion. The primary outcomes were the pooled rates of clinical success (defined as post-POEM Eckardt score ≤3), mean change in Eckardt score, lower esophageal sphincter pressure, and integrated relaxation pressure (IRP). The secondary outcomes were procedure-related adverse events (AEs) and incidence of postoperative GERD. RESULTS A total of 9 studies involving 272 patients with achalasia were recruited in this review. POEM was successfully performed in 270 (99.3%) patients after previous HM. Clinical success was achieved in 90.0% (95% confidence interval [CI], 83.1%-96.8%) of patients. Eckardt score, lower esophageal sphincter pressure, and IRP were significantly lowered by 5.14 (95% CI, 4.19-6.09), 12.01 mm Hg (95% CI, 6.74-17.27), and 10.02 mm Hg (95% CI, 4.95-15.09), respectively. The pooled rates of postoperative symptomatic reflux, esophagitis, and abnormal pH monitoring were 36.9% (95% CI, 20.7%-53.1%), 33.0% (95% CI, 9.6%-56.4%), and 47.8% (95% CI, 33.4%-62.2%), respectively. Substantial heterogeneity was detected across all outcome measurements. Most of the AEs were self-limiting or managed conservatively. CONCLUSIONS POEM is a safe and effective treatment for patients with achalasia with previous HM. Further data from prospective, controlled studies with long-term follow-up are needed to confirm these findings.

Abstract
Achalasia is a rare primary disorder of esophageal motility characterized by insufficient lower esophageal sphincter relaxation and loss of esophageal peristalsis. This results in patient complaints of dysphagia to solids and liquids, regurgitation, chest pain, and weight loss. However, achalasia may also present with respiratory symptoms, such as aspiration pneumonia, due to remarkable regurgitation. In untreated patients and a long period of evolution, respiratory symptoms may even be the initial manifestation of achalasia. An endoscopic finding of retained food and saliva with a puckered gastroesophageal junction or barium swallow showing dilated esophagus with birds beaking in a symptomatic patient should prompt appropriate diagnostic and therapeutic strategies. We describe an atypical presentation of a rare disease in a young man with a history of symptoms caused by the late manifestation of achalasia.

Abstract
BACKGROUND AND AIMS The newest addition in the management of achalasia and esophagogastric junction outflow obstruction (EGJOO) is a 30-mm hydrostatic balloon dilator that uses impedance planimetry technology. It allows for the measurement of the diameter and cross-sectional area to determine effective dilation. We aimed to (1) determine the clinical success (defined as a decrease in Eckardt score to ≤3) in the treatment of esophageal motility disorders and (2) report the safety (rate/severity of adverse events). METHODS This retrospective multicenter study involved 4 centers. Patients with esophageal motility disorders who underwent hydrostatic balloon dilation between January 2015 and October 2018 were included. RESULTS Fifty-one patients (mean age, 54.1 years; women, 49%) underwent hydrostatic dilation for achalasia (n = 37) or EGJOO (n = 14) during the study period. Forty-seven patients had a median baseline Eckardt score of 5 (range, 3-8; achalasia, n = 35, 6 [range, 3-8]; EGJOO, n = 12, 4 [range, 3.25-6.5]). Clinical success was achieved in 60% of cases (achalasia vs EGJOO: 68.4% vs 33.3%, P = .18). Dilation resulted in a significant decrease in the median Eckardt score from 5 (range, 3-8) to 1.5 (range, 1-4.75; P < .001). Patients with achalasia had a decrease in Eckardt score from 6 (range, 3-8) to 1 (range, 1-4; P < .001), whereas those with EGJOO experienced no significant change. One patient had mild postprocedure chest pain. CONCLUSIONS The hydrostatic balloon dilator is a new tool in our armamentarium to treat esophageal motility disorders. This is the first multicenter study showing the device to be safe and moderately efficacious.

Abstract
Background Achalasia is a chronic motility disorder which may require surgical interventions to effectively manage patients’ symptoms and improve functional status. In late stage achalasia, patients may present with sigmoid-shaped esophagus which complicates traditional treatment approaches for achalasia as the esophagus is massively dilated and dysfunctional with delicate tissue integrity. Severe Achalasia with sigmoid esophagus imposes significant challenge to surgeons and treating physicians. Various assessment modalities and treatment approaches have been tried. Surgical treatment continues to be controversial. Some have argued that a less aggressive approach similar to that in early Achalasia results in satisfactory outcomes. Others have argued a more aggressive approach of esophagectomy is necessary. We present a review of the challenges encountered in each approach with recommendation for selecting the right treatment for the individual cases. Conclusions Different treatment options for sigmoid type achalasia are available with ongoing controversy among the options. Heller myotomy with Dor fundoplication can provide satisfactory symptoms improvement and treatment outcomes. Late stage achalasia may present with sigmoid-shaped esophagus. Sigmoid shaped esophagus imposes significant treatment challenges due to dilation and delicate tissue integrity. Surgical treatment continues to be controversial. Heller myotomy with Dor fundoplication can provide satisfactory symptoms improvement and treatment outcomes.

Abstract
Achalasia is a rare esophageal motility disorder characterized by esophageal aperistalsis and impaired relaxation of lower esophageal sphincter. There is no cure for achalasia and all the current treatments are aimed at palliation of symptoms by reducing the lower esophageal sphincter pressure. Currently, laparoscopic Heller myotomy (LHM) with partial fundoplication is considered the most effective and durable treatment option owing to its superiority over other treatments such as pneumatic dilation. Advancements in interventional endoscopy led to a novel minimally invasive endoscopic alternative to LHM, namely peroral endoscopic myotomy (POEM). In the last decade since its inception, POEM expanded rapidly throughout the world due to excellent safety profile and its efficacy comparable to LHM. The main drawback of POEM is gastroesophageal reflux disease since it is not combined with an anti-reflux procedure. The current review focuses on the indications, contraindications, technique, outcomes of POEM in various patient populations, and complications along with its effectiveness in comparison to LHM and pneumatic dilation.

Abstract
BACKGROUND Peroral endoscopic myotomy (POEM) has previously been shown to be equally if not more expensive than laparoscopic Heller myotomy (LHM). We compare perioperative outcomes and charges between POEM and LHM at a single institution. METHODS Outcomes and charge data of 33 patients who underwent LHM and 126 patients who underwent POEM were analyzed. Patients who did not present electively were excluded. RESULTS There were no demographic differences between groups. Patients who underwent POEM had a significantly shorter mean operative time and median length of stay (both p < 0.001). Patients who underwent POEM stopped narcotics earlier and had faster return to activities of daily living (both p < 0.05). When adjusted for inflation, POEM incurred less in hospital charges than LHM (35.5 ± 12.8 vs 30.7 ± 10.3 in thousands of US dollars, p = 0.006). CONCLUSIONS Patients who underwent POEM compared to LHM had significantly better perioperative outcomes. Our results suggest POEM may be the more cost-effective option.

Abstract
Presently, the primary endoscopic options for the treatment of achalasia are peroral endoscopic myotomy (POEM) and pneumatic dilation. But the clinical outcomes of POEM and pneumatic dilation for achalasia have not yet to be fully evaluated. So, we aimed to compare the clinical outcomes between the two treatment modalities. We searched all the relevant studies published up to September 2019 examining the comparative efficacy between POEM and pneumatic dilation. Outcomes included success rate, Eckardt score, lower esophageal sphincter pressure and adverse events. Outcomes were documented by pooled risk ratios and mean difference with 95% confidence interval (CI) using Review Manager 5.3. Seven studies with a total of 619 patients were identified. There were 298 patients underwent POEM treatment and 321 patients underwent pneumatic dilation treatment. The clinical success rate was higher in the POEM group than that in the pneumatic dilation group at 6, 12 and 24 months' follow-up, with a risk ratio of 1.14 (95% CI, 1.06-1.22, P = 0.0002, I= 0%), 1.34 (95% CI, 1.24-1.45, P < 0.00001, I= 17%) and 1.35 (95% CI, 1.10-1.65, P = 0.004, I= 70%), respectively. The change of Eckardt scores was more obvious in the POEM group than in the pneumatic dilation group, with a mean difference of 1.19 (95% CI, 0.78-1.60, P < 0.00001, I= 70%). The rate of gastroesophageal reflux and other complications for POEM was significantly higher than for pneumatic dilation, with a risk ratio of 4.17 (95% CI, 1.52-11.45, P = 0.006, I= 61%) and 3.78 (95% CI, 1.41-10.16, P = 0.008, I= 0%). Our current evidence suggests that the long-term efficacy of POEM was superior to that of pneumatic dilation, but accompanied by higher complications.

Abstract
Background and study aims We aimed to perform an economic evaluation of peroral endoscopic myotomy (POEM) and laparoscopic Heller myotomy (LHM) for the treatment of achalasia. Materials and methods An economic cost-utility analysis was carried out over a time horizon of 1 year. Patients with achalasia who were admitted to the gastroenterology outpatient clinic of a public tertiary referral hospital were assigned to undergo POEM or LHM. The monetary amounts were extracted from the intranet of the institution using microcosting. All costs associated with the procedure, hospitalization, clinical follow-up and resolution of therapeutic complications were included. The utility data were measured in quality-adjusted life years (QALYs), which were estimated from the scores of a quality-of-life questionnaire. Results Forty patients (20 POEM patients and 20 LHM patients) were included. The final cost associated with POEM and LHM was US$ 2,619.19 ± 399.53 and US$ 1,696.44 ± 412.21, respectively ( P < 0.001). However, the QALYs in the POEM group (0.434 ± 0.215 vs 0.332 ± 0.222, P = 0.397) were slightly higher than those in the LHM group. The incremental cost-utility ratio (ICUR) suggested that an additional US$ 9,046.41/QALY gained was required when using POEM. Conclusion For the treatment of achalasia in the public health system, POEM appears to be more cost-effective than LHM in the short term.

Abstract
Since its introduction into clinical practice nearly a decade ago, per-oral endoscopic myotomy (POEM) has now become an accepted minimally invasive approach for the treatment of achalasia with excellent short- and mid-term clinical outcomes in both treatment naïve and those who have failed prior therapy. POEM is comparable to laparoscopic Heller myotomy (LHM) in terms of efficacy and safety, with less procedural pain and faster recovery time. Recent data also reveals that POEM may be more effective and durable than pneumatic dilation (PD) for the treatment of achalasia, with similar safety profile. Preliminary data on POEM for spastic esophageal disorders (SED) is promising yet scarce. Post-POEM gastroesophageal reflux disease (GERD) is common but asymptomatic in most patients, further highlighting the need for ongoing research in this field and the importance of long-term surveillance of these patients.

Abstract
BACKGROUND People with achalasia typically have a thick lower esophageal muscularis propria (LEMP), and peroral endoscopic myotomy (POEM) has been effective in treating most patients. LEMP thickness may be associated with the outcomes and prognosis after POEM. However, more evidence is needed regarding the relationship between LEMP thickness and patient prognosis after POEM.
AIM To assess the association between LEMP thickness, measured using endoscopic ultrasound (EUS), and long-term prognosis, especially relapse, after POEM for achalasia.
METHODS All medical records, including EUS data, of patients who underwent POEM to treat achalasia at Shengjing Hospital of China Medical University from January 2012 to September 2018 were retrospectively reviewed. LEMP thickness was measured by EUS, and a thickness of ≥ 3 mm was defined as thickened. The severity of patient symptoms was evaluated using the Eckardt score. Relapse was defined as a 3-point rise in the Eckardt score after a period of clinical remission. The relationship between patient characteristics, muscle thickness, and recurrence was analyzed.
RESULTS Eighty-two patients (32 males and 50 females, aged 17-78 years) and 85 POEM procedures were included. In total, 76.8% (63/82 patients) of patients had a thickened muscularis propria. Older age and longer disease course were associated with muscularis propria thickening (P < 0.05). The mean postoperative follow-up time was 35.4 ± 17.2 mo (range, 8-87.5 mo) in 60 patients. Five patients with Eckardt scores > 3 refused further management after their symptoms were relieved. The relapse rate was 12.73% (7/55 cases). Five patients, four of whom had muscularis propria thickening, had disease recurrence within 12 mo after the procedure. Achalasia relapsed in one patient who had a thickened muscularis propria after 24 mo and in another patient who did not have a thickened muscularis propria after 30 mo. Patients with recurrence were typically younger and had a shorter disease course (P < 0.05). The relapse rate in patients with a non-thickened muscularis propria tended to be higher (18.2%, 2/11 patients) than that in patients with a thickened muscularis propria (11.4%, 5/44 patients), although no significant difference was found. Age (hazard ratio = 0.92; 95% confidence interval: 0.865-0.979; P < 0.05) and being male (hazard ratio = 7.173; 95% confidence interval: 1.277-40.286; P < 0.05) were identified as risk factors for symptomatic recurrence by multivariable analysis using the Cox model.
CONCLUSION Patients with a thickened muscularis are typically older and have a longer disease course. Younger age and the male sex are associated with increased recurrence. Patients with a thin muscularis propria may be prone to relapse, although further validation is needed.

Abstract
Achalasia is an esophageal motility disorder characterized by aberrant peristalsis and insufficient relaxation of the lower esophageal sphincter. Patients most commonly present with dysphagia to solids and liquids, regurgitation, and occasional chest pain with or without weight loss. High-resolution manometry has identified 3 subtypes of achalasia distinguished by pressurization and contraction patterns. Endoscopic findings of retained saliva with puckering of the gastroesophageal junction or esophagram findings of a dilated esophagus with bird beaking are important diagnostic clues. In this American College of Gastroenterology guideline, we used the Grading of Recommendations Assessment, Development and Evaluation process to provide clinical guidance on how best to diagnose and treat patients with achalasia.

Abstract
BACKGROUND & AIMS The etiologies of esophagogastric junction outflow obstruction (EGJOO) vary, as do their therapeutic implications. We aimed to identify patients with EGJOO most likely to benefit from achalasia-type treatment, based on findings from functional luminal imaging probe (FLIP) panometry. METHODS We performed a retrospective study of 34 patients who received a diagnosis of EGJOO from January 2015 through July 2017. Our analysis included patients who had been evaluated with timed barium esophagram, FLIP, or upper endoscopy. RESULTS Among the 34 patients with idiopathic EGJOO, 7 (21%) had a normal esophagogastric junction distensibility index (EGJ-DI), based on FLIP panometry, and all had repetitive antegrade contractions. None of the patients had radiographic evidence of EGJOO (RAD-EGJOO), defined as liquid barium retention and/or barium tablet impaction. On the other hand, all 18 patients with RAD-EGJOO had an EGJ-DI less than 2 mm2/mm Hg. Nine of the 18 patients with RAD-EGJOO and EGJ-DI less than 2 mm2/mm Hg underwent achalasia-type treatment, and 77.8% of these (7 of 9) had improvements in Eckardt score. Of the 6 patients with a normal EGJ-DI (>3 mm2/mm Hg) who were treated conservatively and followed up, 100% had improvements in subsequent Eckardt scores. CONCLUSIONS We found that FLIP is useful in identifying patients with EGJOO who are most likely to benefit from achalasia-type therapy. Patients with a low EGJ-DI responded well to achalasia-type treatment, whereas patients with normal results from FLIP panometry had good outcomes from conservative management. FLIP panometry might help select management strategies for this difficult population of patients.

Endoscopic ultrasound: a powerful tool to modify treatment algorithms in opioid-induced achalasia. Surg Endosc 2020; 35:4585-4594.

Abstract
BACKGROUND Opioid use in the U.S. has increased dramatically over the last 15 years, recently being declared a public health emergency. Opioid use is associated with esophageal dysmotility lending to a confusing clinical picture compared to true achalasia. Patients exhibit symptoms and elicit diagnostic results consistent with esophageal motility disorders, in particular type III achalasia. Modified therapeutic strategies and outcomes become challenging. Differentiating true achalasia from opioid-induced achalasia is critical. Conventional surgical interventions, i.e., myotomy, are ineffective in the absence of true achalasia. We assess the utility of esophageal muscle layer mapping with endoscopic ultrasound (EUS) in distinguishing primary from opioid-induced achalasia. METHODS From 2016 to 2019, patients with abnormal manometry and suspected achalasia underwent esophagogastroduodenoscopy and EUS mapping of esophageal round muscle layer thickness. Maximum round layer thickness and length of round muscle layer thickness > 1.8 mm were collected and compared between opioid users and non-opioid users using Wilcoxon Rank sum test. RESULTS 45 patients were included: 12 opioid users, 33 non-opioid users. Mean age 56.8 years (range 24-93), 53.3% male patients. Mean BMI in the opioid-induced achalasia group was 30.2 kg/m2, mean BMI in the primary achalasia group 26.8 kg/m2 (p = 0.11). In comparing endoscopic maximum round layer thickness between groups, non-opioid patients had a thicker round muscle layer (2.7 mm vs 1.8 mm, p = 0.05). Length of abnormally thickened esophageal muscle (greater than 1.8 mm) also differed between the two groups; patients on opioids had a shorter length of thickening (4.0 cm vs 0.0 cm, p = 0.04). Intervention rate was higher in the non-opioid group (p = 0.79). Of the patients that underwent therapeutic intervention, symptom resolution was higher in the non-opioid group (p = 0.002), while re-intervention post-procedure for persistent symptomatology was elevated in the opioid subset (p = 0.06). Patients in the opioid group were less likely to undergo invasive treatment (Heller). As of 2017 all interventions in the opioid group have been endoscopic. CONCLUSION Endoscopic ultrasound is an essential tool that has improved our treatment algorithm for suspected achalasia in patients with chronic opioid usage. Incorporation of EUS findings into treatment approach may prevent unnecessary surgery in opioid users.

Abstract
Background Several interventions with variable efficacy are available as first-line therapy for patients with achalasia. We assessed the comparative efficacy of different strategies for management of achalasia, through a network meta-analysis combining direct and indirect treatment comparisons. Methods We identified six randomized controlled trials in adults with achalasia that compared the efficacy of pneumatic dilation (PD; n = 260), laparoscopic Heller myotomy (LHM; n = 309), and peroral endoscopic myotomy (POEM; n = 176). Primary efficacy outcome was 1-year treatment success (patient-reported improvement in symptoms based on validated scores); secondary efficacy outcomes were 2-year treatment success and physiologic improvement; safety outcomes were risk of gastroesophageal reflux disease (GERD), severe erosive esophagitis, and procedure-related serious adverse events. We performed pairwise and network meta-analysis for all treatments, and used GRADE criteria to appraise quality of evidence. Results Low-quality evidence, based primarily on direct evidence, supports the use of POEM (RR [risk ratio], 1.29; 95% confidence intervals [CI], 0.99–1.69), and LHM (RR, 1.18 [0.96–1.44]) over PD for treatment success at 1 year; no significant difference was observed between LHM and POEM (RR 1.09 [0.86–1.39]). The incidence of severe esophagitis after POEM, LHM, and PD was 5.3%, 3.7%, and 1.5%, respectively. Procedure-related serious adverse event rate after POEM, LHM, and PD was 1.4%, 6.7%, and 4.2%, respectively. Conclusions POEM and LHM have comparable efficacy, and may increase treatment success as compared to PD with low confidence in estimates. POEM may have lower rate of serious adverse events compared to LHM and PD, but higher rate of GERD.

Abstract
Objectives: Evaluate the quality of life (QoL) in patients diagnosed with achalasia who performed Heller's myotomy. Methods: Between January 1, 2000 and March 27, 2019, 99 patients were submitted to esophagomyotomy at the São João Hospital in Oporto, Portugal. The exclusion criteria were other diagnoses, age <18 years at the date of surgery, and death. Seventy-five patients were contacted. Pre- and postoperative evaluations were performed using the achalasia disease-specific QoL questionnaire and by the Eckardt score. QoL was assessed by the Medical Outcomes Study SF-36. Results: Forty-nine patients (65%) answered the questionnaires. The median difference in the achalasia-DSQoL questionnaire between the pre- and postoperative period was -9.0 (interquartile range [IQR]: 5-12), whereas in the Eckardt score was -5.0 (IQR: 3.25-7). Lower postoperative scores correlated with higher scores on the SF-36's mental and physical summary measures (Spearman's rho [ρ] = -0.651 and ρ = -0.577 for the achalasia-DSQoL questionnaire and ρ = -0.552 and ρ = -0.515 for the Eckardt score, P < .001). Physical and mental summary measures were correlated with each other (ρ = 0.788, P < .001). Conclusions: Heller's myotomy allows a decrease in symptoms and an increase in QoL. Patients with severe symptoms before surgery had higher postoperative scores and patients with fewer symptoms had lower postoperative scores.

Abstract
Achalasia is a primary motility disorder of the esophagus, and while there are several treatment options, there is no consensus regarding them. When therapeutic intervention for achalasia fails, a careful evaluation of the cause of the persistent or recurrent symptoms using upper endoscopy, esophageal manometry, and contrast radiologic studies is required to understand the cause of therapy failure and guide plans for subsequent treatment. Options for reintervention are the same as for primary intervention and include pneumatic dilation, botulinum toxin injection, peroral endoscopic myotomy, or redo esophageal myotomy. When reintervention fails or if the esophagus is not amenable to intervention and the disease is considered end-stage, esophagectomy is the last option to manage recurrent achalasia.

Abstract
Achalasia is a neurodegenerative motor disease of the esophagus resulting mainly from a loss of function of the lower esophageal sphincter, the pathophysiology of which is still poorly understood. Its incidence is rare—it is 1.6 per 100,000—and its occurrence in the context of paraneoplastic syndrome has been rarely described in the literature. We report a rare case of paraneoplastic achalasia associated with lung cancer.

Abstract
Pseudoachalasia, also known as secondary achalasia, is a clinical condition mimicking idiopathic achalasia but most commonly caused by malignant tumors of gastroesophageal junction (GEJ). Our aim was to systematically review and present all available data on demographics, clinical features, and diagnostic modalities involved in patients with pseudoachalasia. A systematic search of literature published during the period 1978-2019 was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines (end-of-search date: June 25th, 2019). Two independent reviewers extracted data with regards of study design, interventions, participants, and outcomes. Thirty-five studies met our inclusion criteria and were selected in the present review. Overall, 140 patients with pseudoachalasia were identified, of whom 83 were males. Mean patient age was 60.13 years and the mean weight loss was 13.91 kg. A total of 33 (23.6%) patients were wrongly 'treated' at first for achalasia. The most common presenting symptoms were dysphagia, food regurgitation, and weight loss. The median time from symptoms' onset to hospital admission was 5 months. Most common etiology was gastric cancer (19%). Diagnostic modalities included manometry, barium esophagram, endoscopy, and computed tomography (CT). Pseudoachalasia is a serious medical condition that is difficult to be distinguished from primary achalasia. Clinical feature assessment along with the correct interpretation of diagnostic tests is nowadays essential steps to differentiate pseudoachalasia from idiopathic achalasia.

Abstract
The aim of this paper is to review esophageal electrical impedance technologies and to discuss the use of these technologies for physiological measurements, diagnostics, and therapy of esophageal disease. In order to develop a better understanding of the pathophysiology of and improve the diagnosis of esophageal disorders, such as gastroesophageal reflux disease (GERD) and achalasia, several new diagnostic tests, including intraluminal impedance, esophageal mucosal impedance, and the functional luminal imaging probe, have been developed. These technologies have proven valuable for assessment of the esophagus in recent years. They provide information on esophageal flow properties, mucosal integrity, lumen shape, and distensibility in esophageal disorders, in particular for GERD and achalasia. Despite their promise and novel clinical studies, the potential of these technologies has been far from realized. New multidisciplinary approaches will contribute to our understanding and interpretation of esophageal impedance data and disease mechanisms.

Abstract
BACKGROUND & AIMS Identification of factors associated with achalasia treatment outcome might help physicians select therapies based on patient characteristics. We performed a systematic review and meta-analysis to identify factors associated with treatment response. METHODS We searched MEDLINE, EMBASE, and the Cochrane Library through February 21, 2019, for randomized controlled trials and cohort, case-control, and cross-sectional studies that reported patient-specific outcomes of treatment (botulinum toxin injection, pneumatic dilation, peroral endoscopic myotomy, or laparoscopic Heller myotomy). We assessed the methodologic quality of the included studies using the quality in prognosis studies tool. We planned qualitative and quantitative analyses. RESULTS We analyzed data from 75 studies (8 randomized controlled trials, 27 prospective cohort studies, and 40 retrospective studies) on a total of 34 different factors associated with outcomes (3 demographic, 17 clinical, and 14 diagnostic factors). Qualitative assessment showed age, manometric subtype, and presence of a sigmoid-shaped esophagus as factors associated with outcomes of treatment for achalasia with a strong level of evidence. The cumulative evidence for the association with chest pain, symptom severity, and lower esophageal sphincter pressure was inconclusive. A meta-analysis confirmed that older age (mean difference, 7.9 y; 95% CI, 1.5-14.3 y) and manometric subtype 3 (odds ratio, 7.1; 95% CI, 4.1-12.4) were associated with clinical response. CONCLUSIONS In a systematic review and meta-analysis, we found age and manometric subtype to be associated with outcomes of treatment for achalasia. This information should be used to guide treatment decisions.

Wood LS, Chandler JM, Portelli KE, Taylor JS, Kethman WC, Wall JK. Treating children with achalasia using per-oral endoscopic myotomy (POEM): Twenty-one cases in review. J Pediatr Surg 2020; 55:1006-1012. [PMID: 32197825 DOI: 10.1016/j.jpedsurg.2020.02.028] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/07/2020] [Accepted: 02/20/2020] [Indexed: 12/20/2022]
Abstract
BACKGROUND Per-oral endoscopic myotomy (POEM), a modern treatment for achalasia, has only recently emerged as an option for pediatric patients. Here we describe and characterize the success of POEM in children with achalasia. METHODS A single-institution prospective cohort study was performed of patients <18 years old who underwent POEM from 2014 to 2019. Main outcomes were success at one year (Eckardt ≤3), procedure duration, complications, reintervention. RESULTS The median age of patients (n = 21) was 13 years (range 2-17). Median procedure duration was 92 min (range 52-259) with case duration plateau of 87.4 min and learning rate of 15.5 cases. Intraoperative complications included capnoperitoneum requiring needle decompression and mucosotomy requiring additional clips. One patient experienced chest pain with small capnoperitoneum seen on chest radiography, and three patients had extraluminal carbon dioxide found incidentally on routine radiography. All were managed with observation. Pre- versus 1-month postprocedure Eckardt scores were significantly improved (7 ± 2 versus 1 ± 2, p < 0.0001, and median ± SD) with 100% symptomatic relief at one year. To achieve this, 13 patients required further dilation(s), one required laparoscopic Heller myotomy, and two required repeat POEM. CONCLUSIONS POEM is a viable and safe treatment for pediatric patients with achalasia. We demonstrate improvement in symptoms and procedure proficiency with minimal intra- and postoperative complications. TYPE OF STUDY Prospective cohort study. LEVEL OF EVIDENCE Level II.

Triosephosphate isomerase, carbonic anhydrase, and creatinine kinase-brain isoform are possible antigen targets in patients with achalasia. Neurogastroenterol Motil 2020; 32:e13804.

Abstract
BACKGROUND Idiopathic achalasia is an uncommon esophageal motor disorder. The disease involves interaction between inflammatory and autoimmune responses. However, the antigens related to the disease are still unknown. AIM To identify the possible antigen targets in muscle biopsies from lower esophageal sphincter (LES) of achalasia patients. METHODS Esophageal biopsies of patients with type I and type II achalasia and esophagogastric junction outflow obstruction (EGJOO) were analyzed. Lower esophageal sphincter muscle biopsy from a Healthy organ Donor (HD) was included as control for two-dimensional gel electrophoresis. Immunoblotting of muscle from LES lysate with sera of type I, type II achalasia, or type III achalasia, sera of EGJOO and sera of healthy subjects (HS) was performed. The target proteins of the serum were identified by mass spectrometry Matrix-assited laser desorption/ionization time-of-flight (MALDI-TOF). KEY RESULTS The proteomic map of muscle from LES tissue lysates of type I, and type II achalasia, EGJOO, and HD were analyzed and divided into three important regions. We found a difference in the concentration of certain spots. Further, we observed the serum reactivity of type I achalasia and type II achalasia against 45 and 25 kDa bands of type I achalasia tissue. Serum of type III achalasia and EGJOO mainly recognized 25 kDa band. Bands correspond to triosephosphate isomerase (TPI) (25 kDa), carbonic anhydrase (CA) (25 kDa) and creatinine kinase-brain (CKB) isoform (45 kDa). CONCLUSIONS AND INFERENCES We identify three antigen targets, TPI, CA, and CKB isoform, which are recognized by sera from patients with achalasia.

Abstract
BACKGROUND AND AIMS Peroral endoscopic myotomy (POEM) is an available treatment modalities for achalasia. The reported efficacy of POEM in the only prospective multicenter study was 82%; however, a retrospective multicenter study in Japan reported a higher efficacy rate of 95%. The aim of this study was to prospectively verify treatment outcomes after POEM at multiple facilities in Japan. METHODS This was a prospective single-arm trial of POEM for achalasia at 8 facilities in Japan between April 2016 and March 2018 to evaluate its safety and efficacy. Patients were re-evaluated at 3 months and up to 1 year after POEM. RESULTS Among the 233 patients with achalasia who underwent POEM, procedure-related adverse events occurred in 24 patients (10.3%), none of whom required surgical intervention. In the 207 patients satisfying the inclusion criteria, the efficacy rate of POEM, defined by an Eckardt score ≤3 at 1 year, was 97.4% (95% CI, 95.3%-99.7%). The Eckardt score decreased significantly from 6.6 ± 2.0 preoperatively to 1.1 ± 1.1, 1 year after POEM. Postoperative reflux esophagitis, severe reflux esophagitis, and symptomatic GERD were reported in 54.2%, 5.6%, and 14.7%, respectively, and proton pump inhibitors were administered in 21.1%. CONCLUSIONS Our prospective multicenter study in Japan showed greater efficacy of POEM for achalasia compared with the results of a previous prospective multicenter study. POEM is safe and highly effective for at least 1 year. (Clinical trial registration number: UMIN 000021550.).
