ABSTRACT
This editorial is an analysis the review article by Nabi et al recently published in this journal. Achalasia Cardia is a disease whose pathophysiology is still unclear. It is known that there is inflammation of unknown aetiology leading to loss of ganglion cells in the muscularis propria. The end result is lower oesophageal sphincter spasm, loss of receptive relaxation, decreased oesophageal peristalsis, all leading on to varying degrees of dysphagia. The treatment of this condition is palliative in nature, performed by myotomy of the lower oesophagus either surgically or endoscopically. Gastroesophageal reflux disease (GERD) has been associated with the myotomy performed, particularly with the Peroral Endoscopic Myotomy (POEM) procedure. Nabi et al have provided an excellent overview of the latest developments in predicting, preventing, evaluating, and managing GERD subsequent to POEM. Based on this theme, this review article explores the concept of using histology of the oesophageal muscle layer, to grade the disease and thereby help tailoring the length/type of myotomy performed during the POEM procedure. In the future, will a histology based algorithm available preoperatively, help modify the POEM procedure, thereby decreasing the incidence of GERD associated with POEM?

Achalasia is a rare esophageal motility disorder characterized by incomplete lower esophageal sphincter (LES) relaxation, increased LES tone, and absent peristalsis in the esophagus. Management of achalasia includes pneumatic dilation (PD), Botulinum toxin A (BTA) injections to LES, per oral endoscopic myotomy (POEM), and a laparoscopic Heller myotomy (LHM). Situs inversus is a rare congenital condition in which the abdominal and thoracic organs are located in a mirror image of the normal position in the sagittal plane. We herein present a case of a patient with Type II achalasia who underwent an LHM and toupet fundoplication in the setting of an isolated laterality malposition of the liver on the left side of the abdomen. Single organ congenital lateralization defects are extremely rare with literature describing few case reports and case series. A much rarer condition is isolated organ situs inversus. In the foregut, most reports of isolated situs inversus are limited to isolated gastric situs inversus, dextrogastria. Most isolated liver malposition has described situs ambiguous, at the midline, usually associated with polysplenia. Our patient had the normal position of the foregut structures, including the stomach, spleen, pancreas, and duodenum, except for the isolated situs inversus of the liver. Because of the unusual anatomy, performing an LHM was quite challenging. Our workup approach and intraoperative considerations are described. By displacing the larger left lobe of the liver, we were able to safely complete a standard heller myotomy with adequate length and distally across the gastroesophageal junction. Our patient had an uncomplicated post-operative course, and at follow-up has continued to show improvements in her dysphagia and her quality of life.
ABSTRACT
Achalasia is a neurodegenerative disorder affecting esophageal sphincter function. Treatment options include non-surgical and surgical approaches, such as Heller myotomy (HM). Combining Dor fundoplication with HM is controversial but may prevent gastroesophageal reflux disease (GERD). This retrospective cohort study aimed to assess whether HM with Dor fundoplication reduces GERD rates and increases dysphagia rates. Eighty patients who underwent HM between January 2018 and August 2023 were included. Sixty-four patients had Dor fundoplication and were matched 4:1 to 16 patients without fundoplication. Records were reviewed for GERD and achalasia symptoms at various postoperative time points. No significant differences in GERD or dysphagia symptoms were found between the two groups at any time point. Similarly, there were no significant differences in chest pain or dysphagia treatment. In conclusion, this study suggests that the addition of Dor fundoplication to HM does not significantly impact postoperative GERD or achalasia-related symptoms.
ABSTRACT
The peroral endoscopic myotomy (POEM) procedure has revolutionized the management of achalasia in many centres around the world as it offers patients a minimally invasive endoscopic solution to their dysphagia caused by achalasia. Alongside its success in alleviating dysphagia, concerns regarding postoperative gastroesophageal reflux disease have emerged as a pertinent issue which are not fully resolved. In this study, Nabi et al have comprehensively reviewed the topic of the prediction, prevention and management of gastroesophageal reflux after POEM. POEM is a purely endoscopic procedure which is usually performed without any anti-reflux procedure. Certain patients may be better served by a laparoscopic Heller's myotomy and fundoplication and it is important that gastroenterologists and surgeons provide comprehensive risks and benefits of each achalasia treatment option so that patients can decide what treatment is best for them. This article by Nabi et al provides a comprehensive review of the current status of this issue to allow these discussions to occur.

There are various therapeutic options for achalasia. Nevertheless, peroral endoscopic myotomy (POEM) and laparoscopic Heller myotomy with fundoplication (LHM) are distinguished by their efficacy and low incidence of complications. Compare POEM and LHM regarding several outcomes in patients with achalasia. This systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. An exhaustive literature search was performed using PubMed, Web of Science, and Cochrane Library databases. Studies comparing several outcomes between POEM and LHM in patients with achalasia were included. Data on clinical success, operative time, intraoperative complications, length of stay, reintervention rates, postoperative pain, overall complications, occurrence of GERD symptoms, use of proton bomb inhibitors and esophagitis were extracted. Quality assessment of the included studies was performed using the MINORS scale. We included 20 retrospective observational studies with a combined total of 5139 participants. The results demonstrated that there was no statistically significant difference in terms of intraoperative complications, postoperative complications, reintervention rate, occurrence of GERD symptoms, GERD HRQL, use of proton pump inhibitors, and esophagitis between POEM and LHM groups. Conversely, POEM was associated with higher clinical success and shorter operative time, length of stay, and postoperative pain. This meta-analysis concludes that both POEM and LHM, are effective and safe treatments for achalasia. However, POEM demonstrates better results regarding clinical success, operative time, length of stay, postoperative pain, and a tendency towards lower recurrence.

A 14-year-old girl with a history of asthma was hospitalized because of sudden-onset back pain around her thoracic region that spread to her chest and abdomen. She had been experiencing dysphagia and breathing difficulties for two years, especially after overeating, which often resulted in vomiting undigested food. CT imaging revealed a severely dilated esophagus narrowing at the gastroesophageal junction, suggestive of type 1 achalasia. Further testing confirmed the diagnosis, with an esophageal manometry showing a lack of esophageal contractions and sphincter relaxation. She then underwent a laparoscopic Heller myotomy with relief to her symptoms. This case underscores the rarity of pediatric-onset achalasia with significant esophageal dilation and secondary airway compression, presenting with unusual musculoskeletal and respiratory symptoms. Timely diagnosis and treatment are crucial to prevent worsening and complications.
ABSTRACT
BACKGROUND AND OBJECTIVES: Achalasia has several treatment modalities. We aim to compare the efficacy and safety of laparoscopic Heller myotomy (LHM) with those of pneumatic dilatation (PD) in adult patients suffering from achalasia. METHODS: We searched Cochrane CENTRAL, PubMed, Web of Science, SCOPUS and Embase for related clinical trials about patients suffering from achalasia. The quality appraisal and assessment of risk of bias were conducted with GRADE and Cochrane's risk of bias tool, respectively. Homogeneous and heterogeneous data was analyzed under fixed and random-effects models, respectively. RESULTS: The pooled analysis of 10 studies showed that PD was associated with a higher rate of remission at three months, one year, three years and five years (RR = 1.25 [1.09, 1.42] (p = 0.001); RR = 1.13 [1.05, 1.20] (p = 0.0004); RR = 1.48 [1.19, 1.82] (p = 0.0003); RR = 1.49 [1.18, 1.89] (p = 0.001)), respectively. LHM was associated with lower number of cases suffering from adverse events, dysphagia and relapses (RR = 0.50 [0.25, 0.98] (p = 0.04); RR = 0.33 [0.16, 0.71] (p = 0.004); RR = 0.38 [0.15, 0.97] (p = 0.04)), respectively. There is no significant difference between both groups regarding the lower esophageal pressure, perforations, remission rate at two years, Eckardt score after one year and reflux. CONCLUSION: PD had higher remission rates than LHM at three months, one year and three years, but not at two years or five years. More research is needed to determine whether PD has a significant advantage over LHM in terms of long-term remission rates.

Over the last few decades, significant improvement has been made in both the evaluation and treatment of esophageal achalasia. The Chicago classification, today in version 4.0, is now the standard for diagnosis of achalasia, providing a classification into 3 subtypes with important therapeutic and prognostic implications. Therapy, which was at first mostly limited to pneumatic dilatation, today includes minimally invasive surgery and peroral endoscopic myotomy, allowing for a more tailored approach to patients and better treatment of recurrent symptoms. This review chronicles my personal experience with achalasia over the last 35 years, describing the progress made in the treatment of patients with achalasia.

Achalasia is a motility disorder of the esophagus in which the lower esophageal sphincter fails to relax. Megaesophagus is a rare complication of achalasia characterized by severe dilatation of the esophagus, often indicative of end-stage achalasia. Typical presenting symptoms include dysphagia, nausea, vomiting, weight loss, and chest pain. The majority of patients with achalasia typically have excellent outcomes after surgical intervention with Heller myotomy. We discuss an interesting case of unsuccessful surgical intervention and hypothesize the reason for its failure in our patient.
ABSTRACT
BACKGROUND: Systemic inflammatory response is significant prognostic indicator in patients with various diseases. The relationship between prognostic scoring systems based on the modified Glasgow Prognostic Score (mGPS) and achalasia in patients treated with laparoscopic Hellermyotomy with Dorfundoplication (LHD) remains uninvestigated. This study aimed to examine the role of mGPS in patients with achalasia. METHODS: 457 patients with achalasia who underwent LHD as the primary surgery between September 2005 and December 2020 were included. We divided patients into the mGPS 0 and mGPS 1 or 2 groups and compared the patients' background, pathophysiology, symptoms, surgical outcomes, and postoperative course. RESULTS: mGPS was 0 in 379 patients and 1 or 2 in 78 patients. Preoperative vomiting and pneumonia were more common in patients with mGPS of 1 or 2. There were no differences in surgical outcomes. Postoperative upper gastrointestinal endoscopy revealed that severe esophagitis was more frequently observed in patients with mGPS of 1 or 2 (P < 0.01). The clinical success was 91% and 99% in the mGPS 0 and mGPS 1 or 2 groups, respectively (P < 0.01). CONCLUSIONS: Although severe reflux esophagitis was more common in patients with achalasia with a high mGPS, good clinical success was obtained regardless of the preoperative mGPS.

BACKGROUND: Achalasia is a rare disorder of the esophagus characterized by motor dysfunction in the esophagus and relaxation failure of the lower esophageal sphincter (LES). Currently, surgical myotomy procedures are considered the standard of care. Robotic Heller's myotomy (RHM) with fundoplication has been gaining popularity due to documented advantages in the precision of myotomy as well as avoiding the potential reflux following per-oral endoscopic myotomy (POEM). To the best of our knowledge, RHM has thus far has been performed exclusively by the da Vinci surgical system. The new Hugo RAS™ system offers a unique modular design and an open console which offers better maneuverability and docking options. In this study, we present the first worldwide series of patients undergoing RHM using the new Hugo RAS™ platform. Our objective is to propose optimal operating configuration and setup to fully harness the advantages of the unique modular design of this system. METHODS: Ten consecutive achalasia patients underwent Robotic Heller's myotomy (RHM) with the Hugo RAS™ system. We prospectively collected patient data, including demographics, comorbidities, ASA class, Eckardt scores, pre-operative manometric data, and EndoFlip parameters. Additionally, we recorded the docking and total operative times. RESULTS: Between December 2022 and August 2023, 10 patients underwent RHM with the Hugo™ RAS system. Patients had a median age of 42.5 years, 60% were female, and mean BMI was 23.2. Fifty percent had achalasia type 2 and 50% type 1. The median pre-operative integrated relaxation pressure (IRP) was 24.9. Median docking time was 10 min and overall operative time was 129.5 min. All patients, except one with acute coronary syndrome, had an uneventful peri-operative course and were discharged on post-operative day 2. CONCLUSION: The Hugo™ RAS system is well designed for robotic Heller myotomy. The operative and clinical results are similar to the currently used robotic system; however, the modular design of the system has some differences. These translate to better docking angles and maneuverability as well as console surgeon's ergonomics. Further experience is needed to explore the advantages of the system's modular design and function.

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

Disorders of esophagogastric junction (EGJ) outflow, including achalasia and EGJ outflow obstruction, are motility disorders characterized by inadequate relaxation of lower esophageal sphincter with or without impaired esophageal peristalsis. Current guidelines are technical and less practical in the Asia-Pacific region, and there are still massive challenges in timely diagnosis and managing these disorders effectively. Therefore, a Malaysian joint societies' task force has developed a consensus on disorders of EGJ outflow based on the latest evidence, while taking into consideration the practical relevance of local and regional context and resources. Twenty-one statements were established after a series of meetings and extensive review of literatures. The Delphi method was used in the consensus voting process. This consensus focuses on the definition, diagnostic investigations, the aims of treatment outcome, non-surgical or surgical treatment options, management of treatment failure or relapse, and the management of complications. This consensus advocates the use of high-resolution esophageal manometry for diagnosis of disorders of EGJ outflow. Myotomy, via either endoscopy or laparoscopy, is the preferred treatment option, while pneumatic dilatation can serve as a secondary option. Evaluation and management of complications including post-procedural reflux and cancer surveillance are recommended.

ABSTRACT BACKGROUND: Videolaparoscopic esophagocardiomyotomy with fundoplication has been a widely used technique for the treatment of achalasia. This study analyzes the safety and effectiveness of the technique in the treatment of non-advanced achalasia (megaesophagus) in a Brazilian federal university public hospital. AIMS: To evaluate the short- and long-term results of videolaparoscopic treatment of non-advanced megaesophagus in a public university hospital in Brazil, employing the esophagocardiomyotomy technique with fundoplication. METHODS: The medical records of 44 patients who underwent surgical treatment for non-advanced achalasia at the Clinical Hospital of Federal University of Uberlândia (UFU-MG), Minas Gerais, from January 2001 to July 2021 were analyzed. The following data were evaluated: gender, age, etiology, radiological classification of Rezende-Alves and Ferreira-Santos, immediate and late complications (mean follow-up of 31.4 months), need or not for conversion to open access, postoperative reflux, performance or not of endoscopic esophageal dilation in the preoperative period, postoperative mortality, frequency of pre and postoperative symptoms (persistent dysphagia, regurgitation, heartburn, vomiting, odynophagia, and weight loss), surgery time, hospital stay, duration of dysphagia, pre and postoperative weight, and Eckardt score. RESULTS: Among the analyzed patients, 23 (52.3%) were male, and 21 (47.7%) were female, with a mean age of 50.8 years. No early complications were recorded and there were 27.2% cases of late gastroesophageal reflux. Postoperative weight gain was 81.8% and the success rate of surgery according to the Eckardt score was 84.1%. CONCLUSIONS: Esophagocardiomyotomy with fundoplication is an effective and safe technique for the treatment of non-advanced achalasia.

RESULTADOS: Entre os pacientes analisados, 23 (52,3%) eram do sexo masculino e 21 (47,7%) eram do sexo feminino, com média de idade de 50,8 anos. Não foram registradas complicações precoces e houve 27,2% de casos de refluxo gastroesofágico. O ganho de peso no pós-operatório foi de 81,8% e a taxa de sucesso da cirurgia segundo o escore de Eckardt foi de 84,1%. CONCLUSÕES: A esofagocardiomiotomia com válvula antirrefluxo por videolaparoscopia é uma técnica eficaz e segura para o tratamento da acalasia não avançada.
ABSTRACT
INTRODUCTION: With the advent of the laparoscopic era in the 1990s, laparoscopic Heller myotomy replaced pneumatic dilation as the first-line treatment for achalasia. An advantage of this approach was the addition of a fundoplication to reduce gastroesophageal reflux disease (GERD). More recently, Peroral Endoscopic Myotomy has competed for first-line therapy, but the postoperative GERD may be a weakness. This study leverages our experience to characterize GERD following LHM with Toupet fundoplication (LHM+T ) so that other treatments can be appropriately compared. METHODS: A single-institution retrospective review of adult patients with achalasia who underwent LHM+T from January 2012 to April 2022 was performed. We obtained routine 6-month postoperative pH studies and patient symptom questionnaires. Differences in questionnaires and reflux symptoms in relation to pH study were explored via Kruskal-Wallis test or chi-square tests. RESULTS: Of 170 patients who underwent LHM+T , 51 (30%) had postoperative pH testing and clinical symptoms evaluation. Eleven (22%) had an abnormal pH study; however, upon manual review, 5 of these (45.5%) demonstrated low-frequency, long-duration reflux events, suggesting poor esophageal clearance of gastric refluxate and 6/11 (54.5%) had typical reflux episodes. Of the cohort, 7 (15.6%) patients reported GERD symptoms. The median [IQR] severity was 1/10 [0, 3] and median [IQR] frequency was 0.5/4 [0, 1]. Patients with abnormal pH reported more GERD symptoms than patients with a normal pH study (3/6, 50% vs 5/39, 12.8%, p = 0.033). Those with a poor esophageal clearance pattern (n = 5) reported no concurrent GERD symptoms. CONCLUSION: The incidence of GERD burden after LHM+T is relatively low; however, the nuances relevant to accurate diagnosis in treated achalasia patients must be considered. Symptom correlation to abnormal pH study is unreliable making objective postoperative testing important. Furthermore, manual review of abnormal pH studies is necessary to distinguish GERD from poor esophageal clearance.

Robot-assisted Heller myotomy (RAHM) is an increasingly popular alternative to the traditional laparoscopic Heller myotomy (LHM) in the surgical management of achalasia, with similar outcomes and potentially lower complication rates. We aimed to systematically review the literature by comparing the technical success, outcomes, and complications of RAHM and LHM. We searched PubMed, Medline, and Cochrane Central Register for articles published between 2001 and 2023. Data on technical success, clinical outcomes, length of hospital stay, esophageal perforation rate, and overall mortality were extracted. A total of 11 articles were included in the study, comparing a total of 3,543 RAHM and 15,434 LHM cases. The mean operative time was significantly higher in the RAHM procedure with a total mean difference of 23.95 (95% confidence interval (Cl) 17.09, 30.81; p < 0.00001; I2 = 99%). However, the RAHM was associated with a significantly shorter hospital stay, with a total mean difference of -0.24 (95% Cl = -0.40, -0.08; p < 0.00001; I2 = 81%). The volume of blood loss was significantly smaller in RAHM with a total mean difference of -61.11 (95% CI = -150.31, 28.09; p < 0.00001; I2 = 99%). Esophageal mucosal perforation was significantly lower in RAHM with an odds ratio of 0.36 (95% CI = 0.16, 0.82; p = 0.02; I2 = 22%). Both procedures were associated with similar rates of symptom relief. Although no mortality was recorded in patients who underwent RAHM as opposed to 16 cases in patients who underwent LHM, no statistically significant difference could be reached. Our results demonstrate that while both procedures yield comparable clinical outcomes, RAHM is associated with a lower overall complication rate, particularly a lower rate of esophageal mucosal perforation, shorter hospital stay, and possibly a lower mortality rate. This confirms that RAHM is a viable and justifiable alternative to the conventional LHM in the surgical management of achalasia.
ABSTRACT
BACKGROUND: Video-assisted laparoscopic Heller myotomy (LHM) has become the standard treatment option for achalasia. While robotic surgery offering some specific advantages such as better three-dimensional (3D) stereoscopic vision, hand-eye consistency, and flexibility and stability with the endowrist is expected to be shorter in learning curve than that of LHM for surgeons who are proficient in LHM. The aim of this study was to describe a single surgeon's experience related to the transition from video-assisted laparoscopic to robotic Heller myotomy with Dor fundoplication. METHODS: We conducted a retrospective observational study based on the recorded data of the first 66 Heller myotomy performed with laparoscopic Heller myotomy with Dor fundoplication (LHMD, 26 cases) and with the robotic Heller myotomy with Dor fundoplication (RHMD, 40 cases) by the same surgeon in Department of Thoracic Surgery of The First Affiliated Hospital of Nanchang University in China. The operation time and intraoperative blood loss were analyzed using the cumulative sum (CUSUM) method. Corresponding statistical tests were used to compare outcomes of both serials of cases. RESULTS: The median operation time was shorter in the RHMD group compared to the LHMD group (130 [IQR 123-141] minutes vs. 163 [IQR 153-169]) minutes, p < 0.001). In the RHMD group, one patient (2.5%) experienced mucosal perforation, whereas, in the LHMD group, the incidence of this complication was significantly higher at 19.2% (5 patients) (p = 0.031). Based on cumulative sum analyses, operation time decreased starting with case 20 in the LHMD group and with case 18 in the RHMD group. Intraoperative blood loss tended to decline starting with case 19 in the LHMD group and with case 16 in the RHMD group. CONCLUSIONS: Both RHMD and LHMD are effective surgical procedures for symptom relief of achalasia patients. RHMD demonstrates superior outcomes in terms of operation time and mucosal perforation during surgery compared to LHMD. Proficiency with RHMD can be achieved after approximately 16-18 cases, while that of LHMD can be obtained after around 19-20 cases.

INTRODUCTION: Achalasia is a rare esophageal motility disorder characterized by abnormal esophageal peristalsis and the inability of the lower esophageal sphincter to relax, resulting in poor esophageal emptying. This can be relieved by endoscopic and surgical treatments; each comes with certain advantages and disadvantages. AREAS COVERED: This review aims to guide the clinician in clinical decision making on the different treatment options for achalasia regarding the efficacy, safety, and important predictors. EXPERT OPINION: Botulinum toxin injection is only recommended for a selective group of achalasia patients because of the short term effect. Pneumatic dilation improves achalasia symptoms, but this effect diminishes over time and requiring repeated dilations to maintain clinical effect. Heller myotomy combined with fundoplication and peroral endoscopic myotomy are highly effective on the long term but are more invasive than dilations. Gastro-esophageal reflux complaints are more often encountered after peroral endoscopic myotomy. Patient factors such as age, comorbidities, and type of achalasia must be taken into account when choosing a treatment. The preference of the patient is also of great importance and therefore shared decision making has to play a fundamental role in deciding about treatment.
