BACKGROUND: The majority of esophageal subepithelial lesions originating from the muscularis propria (SEL-MPs) are benign in nature, although a subset may exhibit malignant characteristics. Conventional endoscopic resection techniques are time-consuming and lack efficacy for small SEL-MPs. AIM: To evaluate the efficacy and safety of ligation-assisted endoscopic submucosal resection (ESMR-L) following unroofing technique for small esophageal SEL-MPs. METHODS: From January 2021 to September 2023, 17 patients diagnosed with esophageal SEL-MPs underwent ESMR-L following unroofing technique at the endoscopy center of Shenzhen People's Hospital. Details of clinicopathological characteristics and clinical outcomes were collected and analyzed. RESULTS: The mean age of the patients was 50.12 ± 12.65 years. The mean size of the tumors was 7.47 ± 2.83 mm and all cases achieved en bloc resection successfully. The average operation time was 12.2 minutes without any complications. Histopathology identified 2 Lesions (11.8%) as gastrointestinal stromal tumors at very low risk, 12 Lesions (70.6%) as leiomyoma and 3 Lesions (17.6%) as smooth muscle proliferation. No recurrence was found during the mean follow-up duration of 14.18 ± 9.62 months. CONCLUSION: ESMR-L following roofing technique is an effective and safe technique for management of esophageal SEL-MPs smaller than 20 mm, but it cannot ensure en bloc resection and may require further treatment.

Achalasia, a rare esophageal motility disorder characterized by the inability of the lower esophageal sphincter to relax and loss of esophageal peristalsis, significantly impacts pediatric patient quality of life through symptoms like dysphagia, chest pain, and weight loss. This nationwide retrospective cohort study evaluates the efficacy and safety of peroral endoscopic myotomy (POEM) for pediatric achalasia in Mongolia, contributing to the limited global data on this minimally invasive treatment in children. Conducted between February 2020 and March 2022 at 2 tertiary centers, the study included symptomatic achalasia patients, treatment-naive or those with unsatisfactory outcomes from previous esophageal dilations. The POEM procedure was assessed for its impact on esophageal structure and function, symptom severity via the Eckardt score, and procedure-related safety, with outcomes measured at baseline, 3 days, and 12 months post-procedure. The study demonstrated notable post-procedure improvements across all measured outcomes: abnormal contraction length and esophageal width significantly reduced, underscoring the procedure's effectiveness. More precisely, the integrated relaxation pressure showed a significant improvement from a mean of 26.8 mm Hg (standard deviation [SD], 5.4 mm Hg) pre-procedure to 10.8 mm Hg (SD, 1.1 mm Hg) 12 months (Pâ <â .001). Similarly, Eckardt scores, which assess symptom severity, improved significantly from a pre-procedure mean of 7.0 (SD, 1.0) to a substantially lower score post-procedure (Pâ <â .001), reflecting enhanced patient quality of life and symptom alleviation. This study underscores POEM's role as an effective, minimally invasive option for pediatric achalasia management within the Mongolian population, offering significant symptomatic relief and improved esophageal function.

Achalasia can significantly impair the quality of life. The clinical presentation typically includes dysphagia to both solids and liquids, chest pain, and regurgitation. Diagnosis can be delayed in patients with atypical presentations, and they might receive a wrong diagnosis, such as gastroesophageal reflux disease (GERD), owing to overlapping symptoms of both disorders. Although the cause of achalasia is poorly understood, its impact on the motility of the esophagus and gastroesophageal junction is well established. Several treatment modalities have been utilized, with the most common being surgical Heller myotomy with concomitant fundoplication and pneumatic balloon dilatation. Recently, peroral endoscopic myotomy (POEM) has gained popularity as an effective treatment for achalasia, despite a relatively high incidence of GERD occurring after treatment compared to other modalities. The magnitude of post-POEM GERD depends on its definition and is influenced by patient and procedure-related factors. The long-term sequelae of post-POEM GERD are yet to be determined, but it appears to have a benign course and is usually manageable with clinically available modalities. Identifying risk factors for post-POEM GERD and modifying the POEM procedure in selected patients may improve the overall success of this technique.

Achalasia, characterized by impaired lower esophageal sphincter (LES) relaxation and failed peristalsis, stands out as the most widely recognized primary esophageal motility disorder. It manifests with dysphagia to solid and liquid foods, chest pain, regurgitation, and weight loss, leading to significant morbidity and healthcare burden. Traditionally, surgical Heller myotomy and pneumatic dilation were the primary therapeutic approaches for achalasia. However, in 2009, Inoue and colleagues introduced a groundbreaking endoscopic technique called peroral endoscopic myotomy (POEM), revolutionizing the management of this condition. This review aims to comprehensively examine the recent advancements in the POEM technique for patients diagnosed with achalasia, delving into critical aspects, such as the tailoring of the myotomy, the prevention of intraprocedural adverse events (AEs), the evaluation of long-term outcomes, and the feasibility of retreatment in cases of therapeutic failure.

Peroral endoscopic myotomy (POEM) is the preferred endoscopic modality for managing achalasia cardia. However, there are no recommendations on the role of POEM in nonachalasia esophageal dysmotility disorders (NAEMD), including esophagogastric junction outflow obstruction (EGJOO), distal esophageal spasm (DES), and hypercontractile esophagus (HE). The present systematic review and meta-analysis aimed to assess the safety and efficacy of POEM in the treatment of NAEMD. MEDLINE, Embase, and Scopus were searched from inception to August 2023 for studies analyzing the outcome of POEM in NAEMD. Clinical success and adverse events were the main outcomes assessed. The event rates and their 95% confidence interval were calculated using a random effects model. A total of 11 studies with 271 patients were included in the final analysis. The pooled clinical success rate with POEM in NAEMD was 86.9% (82.9-90.9). On subgroup analysis, the pooled clinical success rates of POEM in DES and EGJOO were 97.8% (90.9-100.0) and 92.7% (86.3-95.1), which were significantly higher than in HE 81.2% (73.5-88.8). Data from limited studies showed that the pooled rate of improvement in dysphagia and chest pain was 88.5% (83.0-93.9) and 87.4% (80.5-94.4). The pooled incidence of overall AEs and serious AEs was 12.6% (5.7-19.5) and 0.3% (0.0-1.9), respectively. On follow-up, the pooled incidence of new-onset heartburn was 18.7% (11.1-26.2). POEM is a safe and efficacious treatment modality for the management of NAEMD with a lower clinical success in patients with HE. Further large-scale studies are required to validate the findings of the present analysis.

INTRODUCTION: Minimally invasive endoscopic options are safe and effective alternatives to surgery for the treatment of symptomatic Zenker's diverticulum (ZD). However, there is no consensus on the gold-standard approach. We compared the safety and efficacy of Zenker's peroral endoscopic myotomy (Z-POEM), flexible diverticulotomy (FD), and rigid diverticulotomy (RD) for the management of ZD. METHODS: Patients undergoing treatment for ZD at three UK tertiary referral centres were identified and analysed between 2013 and 2023. Patient demographics, procedural details, clinical success, and 30-day adverse events (AE) were recorded. The primary outcomes were technical and clinical success defined as a fall in Dakkak and Bennett dysphagia score to ≤ 1 without re-intervention. RESULTS: There was no difference in baseline characteristics amongst 126 patients undergoing intervention (50 RD, 31 FD, 45 Z-POEM). Technical success for RD, FD, and Z-POEM was 80%, 100%, and 100%, respectively (p < 0.001). Over a mean follow-up of 11.0 months (95% CI 8.2-13.9), clinical success amongst those treated was 85.3% (RD), 74.1% (FD), and 83.7% (Z-POEM; p = 0.48) with recurrence in 17.2% (RD), 20.0% (FD), and 8.3% (Z-POEM; p = 0.50). AEs were equivalent between groups (p = 0.98). During this time, 11 patients underwent surgical myotomy with low clinical success (36.4%) and high morbidity. CONCLUSION: Endoscopic options for the treatment of ZD show equivalent rates of success, but failed RD often led to open myotomy with worse outcomes. Flexible endoscopic modalities are both safe and highly effective treatments that may be considered first-line in experienced centres and should be offered before surgery.

BACKGROUND: Endoscopic resection (ER) is a minimally invasive treatment for esophageal cancer that sometimes causes complications. To understand the real-world incidence and risk factors for these complications, a nationwide survey was conducted across Japan. METHODS: This retrospective multicenter study included patients who underwent ER for esophageal cancer from April 2017 to March 2018 (2017 complication analysis) and April 2021 to March 2022 (2021 complication analysis). The study assessed the complication rates and conducted risk factor analyses for endoscopic submucosal dissection (ESD) using data for these patients, with exclusions based on specific criteria to ensure data accuracy. RESULTS: In the 2021 complication analysis, there were two mortalities highly likely attributable (0.03%) to ER and one mortality possibly attributable (0.01%) to ER. Intraoperative perforation, delayed bleeding, and pneumonia occurred in 137 cases (1.8%), 44 cases (0.6%), and 130 cases (1.7%), respectively. In the multivariate analysis for complications after ESD, low ER volume of the facility was an independent risk factor for perforation, while lesion location in the cervical or upper thoracic esophagus was an independent factor for reduced risk of perforation. Age ≥ 80 years was a risk factor for pneumonia, while use of traction techniques was a factor for reduced risk of pneumonia. Lesions located in the middle thoracic esophagus had a lower risk of stricture, and the risk of stricture increased as the circumferential extent of the lesion increased. CONCLUSIONS: This large-scale study provided detailed insights into the complications associated with esophageal ER and identified significant risk factors.

OBJECTIVE: Assessment of the effect of continuous cuff pressure control on airway injury in middle-aged and elderly patients undergoing endoscopic submucosal dissection (ESD). METHOD: A total of 104 eligible middle-aged and elderly patients requiring esophageal ESD from July 2022-September 2023 at the First Affiliated Hospital of Nanchang University were selected and randomly divided into two groups: the group undergoing general anesthesia tracheal intubation with continuous control of cuff pressure after intubation (Group A, n = 51) and the group undergoing general anesthesia tracheal intubation with continuous monitoring without control of cuff pressure (Group B, n = 53). After endotracheal intubation in Group A, under the guidance of an automatic cuff pressure controller, the air was used to inflate the tracheal cuff until the cuff pressure was 25-30cmH2O. The cuff pressure after intubation was recorded, and then the cuff pressure parameters were directly adjusted in the range of 25-30cmH2O until tracheal extubation after the operation. After endotracheal intubation, patients in Group B inflated the tracheal cuff with clinical experience, then monitored and recorded the cuff pressure with a handheld cuff manometer and instructed the cuff not to be loosened after being connected to the handheld cuff manometer-continuous monitoring until the tracheal extubation, but without any cuff pressure regulation. The patients of the two groups performed esophageal ESD. The left recumbent position was taken before the operation, and the cuff's pressure was recorded. Then, insert the gastrointestinal endoscope to find the lesion site and perform appropriate CO2 inflation to display the diseased esophageal wall for surgical operation fully. After determining the location, the cuff pressure of the two groups was recorded when the cuff pressure was stable. After the operation, the upper gastrointestinal endoscope was removed and the cuff pressure of the two groups was recorded. Postoperative airway injury assessment was performed in both groups, and the incidence of sore throat, hoarseness, cough, and blood in sputum was recorded. The incidence of postoperative airway mucosal injury was also observed and recorded in both groups: typical, episodic congestion spots and patchy local congestion. RESULT: The incidence of normal airway mucosa in Group A was higher than that in Group B (P < 0.05). In comparison, the incidence of occasional hyperemia and local plaque congestion in Group A was lower than in Group B (P < 0.05). CONCLUSION: Continuous cuff pressure control during operation can reduce airway injury in patients with esophageal ESD and accelerate their early recovery after the operation.

BACKGROUND: Repeat endoscopic submucosal dissection for metachronous recurrence of esophageal squamous cell carcinoma close to previous endoscopic submucosal dissection scars is challenging. Therefore, this study evaluated the efficacy and safety of repeat endoscopic submucosal dissection for recurrent esophageal squamous cell carcinoma. METHODS: The study included 1680 patients. After propensity score matching, esophageal endoscopic submucosal dissection-related outcomes were compared between the post-endoscopic submucosal dissection scar group (n = 91) and first endoscopic submucosal dissection group (n = 910). The Kaplan-Meier method and log-rank tests were used to compare both groups' survival and local recurrence curves. RESULTS: After propensity score matching, the two groups showed no significant difference in en bloc resection rate (97.80% vs. 99.56%, p = 0.096), treatment time (64.75 min vs 61.33 min, p = 0.448), recurrence rate (3.30% vs. 2.20%, p = 0.458), and stricture rate (7.69% vs. 4.07%, p = 0.110). However, the perforation rate was higher in the post-endoscopic submucosal dissection scar group than in the first endoscopic submucosal dissection group (4.40% vs. 1.10%, p = 0.031). The 5-year overall survival rates in the post-endoscopic submucosal dissection scar and first endoscopic submucosal dissection groups were 88.6% and 89.0%, respectively. CONCLUSIONS: Repeated esophageal endoscopic submucosal dissection for recurrent esophageal squamous cell carcinoma yielded satisfactory clinical outcomes and survival rates. Therefore, repeat endoscopic submucosal dissection may effectively treat esophageal squamous cell carcinoma recurrence close to the initial endoscopic submucosal dissection scars.

In this editorial, we respond to a review article by Nabi et al, in which the authors discussed gastroesophageal reflux (GER) following peroral endoscopic myotomy (POEM). POEM is presently the primary therapeutic option for achalasia, which is both safe and effective. A few adverse effects were documented after POEM, including GER. The diagnostic criteria were not clear enough because approximately 60% of patients have a long acid exposure time, while only 10% experience reflux symptoms. Multiple predictors of high disease incidence have been identified, including old age, female sex, obesity, and a baseline lower esophageal sphincter pressure of less than 45 mmHg. Some technical steps during the procedure, such as a lengthy or full-thickness myotomy, may further enhance the risk. Proton pump inhibitors are currently the first line of treatment. Emerging voices are increasingly advocating for the routine combining of POEM with an endoscopic fundoplication method, such as peroral endoscopic fundoplication or transoral incisionless fundoplication. However, more research is necessary to determine the safety and effectiveness of these procedures in the long term for patients who have undergone them.

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?

BACKGROUND: Although esophageal achalasia has been historically treated by Heller myotomy, endoscopic esophageal dilatations are nowadays often the first-line treatment in children. The aim was to assess whether performing an endoscopic dilatation before a Heller myotomy is associated with higher risks of esophageal perforation in children. METHODS: A retrospective multicentric study was performed, including children that underwent a Heller myotomy (2000-2022, 10 centers). Two groups were compared based on the history of previous dilatation before myotomy. Outcomes esophageal perforation (intra-operative or secondary) and post-operative complications requiring surgery (Clavien-Dindo III). Statistics Comparisons using contingency tables or Kruskal-Wallis when appropriate. Statistical significance: p-value < 0.05. RESULTS: A Heller myotomy was performed in 77 children (median age: 11.8 years), with prior endoscopic dilatation in 53% (n = 41). A laparoscopic approach was used in 90%, with associated fundoplication in 95%. Esophageal perforation occurred in 19% of children (n = 15), including 12 patients with intra-operative mucosal tear and 3 with post-operative complications related to an unnoticed esophageal perforation. Previous endoscopic dilatation did not increase the risk of esophageal perforation (22% vs 17%, OR: 1.4, 95%CI: 0.43-4.69). Post-operative complications occurred in 8% (n = 6), with similar rates regardless of prior endoscopic dilatation. Intra-operative mucosal tear was the only risk factor for post-operative complications, increasing the risk of complications from 5 to 25% (OR: 6.89, 95%CI: 1.38-31.87). CONCLUSIONS: Prior endoscopic dilatations did not increase the risk of esophageal perforation or postoperative complications of Heller myotomy in this cohort of children with achalasia. Mucosal tear was identified as a risk factor for post-operative complications.

BACKGROUND & AIMS: Barrett's esophagus (BE) is the precursor to esophageal adenocarcinoma (EAC). Endoscopic eradication therapy (EET) can be effective in eradicating BE and related neoplasia and has greater risk of harms and resource use than surveillance endoscopy. This clinical practice guideline aims to inform clinicians and patients by providing evidence-based practice recommendations for the use of EET in BE and related neoplasia. METHODS: The Grading of Recommendations Assessment, Development and Evaluation framework was used to assess evidence and make recommendations. The panel prioritized clinical questions and outcomes according to their importance for clinicians and patients, conducted an evidence review, and used the Evidence-to-Decision Framework to develop recommendations regarding the use of EET in patients with BE under the following scenarios: presence of (1) high-grade dysplasia, (2) low-grade dysplasia, (3) no dysplasia, and (4) choice of stepwise endoscopic mucosal resection (EMR) or focal EMR plus ablation, and (5) endoscopic submucosal dissection vs EMR. Clinical recommendations were based on the balance between desirable and undesirable effects, patient values, costs, and health equity considerations. RESULTS: The panel agreed on 5 recommendations for the use of EET in BE and related neoplasia. Based on the available evidence, the panel made a strong recommendation in favor of EET in patients with BE high-grade dysplasia and conditional recommendation against EET in BE without dysplasia. The panel made a conditional recommendation in favor of EET in BE low-grade dysplasia; patients with BE low-grade dysplasia who place a higher value on the potential harms and lower value on the benefits (which are uncertain) regarding reduction of esophageal cancer mortality could reasonably select surveillance endoscopy. In patients with visible lesions, a conditional recommendation was made in favor of focal EMR plus ablation over stepwise EMR. In patients with visible neoplastic lesions undergoing resection, the use of either endoscopic mucosal resection or endoscopic submucosal dissection was suggested based on lesion characteristics. CONCLUSIONS: This document provides a comprehensive outline of the indications for EET in the management of BE and related neoplasia. Guidance is also provided regarding the considerations surrounding implementation of EET. Providers should engage in shared decision making based on patient preferences. Limitations and gaps in the evidence are highlighted to guide future research opportunities.

BACKGROUND: This study evaluated the safety and efficacy of salvage endoscopic submucosal dissection (ESD) for Barrett's neoplasia recurrence after radiofrequency ablation (RFA). METHODS: Data from patients at 16 centers were collected for a multicenter retrospective study. Patients who underwent at least one RFA treatment for Barrett's esophagus and thereafter underwent further esophageal ESD for neoplasia recurrence were included. RESULTS: Data from 56 patients who underwent salvage ESD between April 2014 and November 2022 were collected. Immediate complications included one muscular tear (1.8%) treated with stent (Agree classification: grade IIIa). Two transmural perforations (3.6%; treated with clips) and five muscular tears (8.9%; two treated with clips) had no clinical impact and were not considered as adverse events. Seven patients (12.5%) developed strictures (grade IIIa), which were treated with balloon dilation. Histological analysis showed 36 adenocarcinoma, 17 high grade dysplasia, and 3 low grade dysplasia. En bloc and R0 resection rates were 89.3% and 66.1%, respectively. Resections were curative in 33 patients (58.9%), and noncurative in 22 patients (39.3%), including 11 "local risk" (19.6%) and 11 "high risk" (19.6%) resections. At the end of follow-up with a median time of 14 (0-75) months after salvage ESD, and with further endoscopic treatment if necessary (RFA, argon plasma coagulation, endoscopic mucosal resection, ESD), neoplasia remission ratio was 37/53 (69.8%) and the median remission time was 13 (1-75) months. CONCLUSION: In expert hands, salvage ESD was a safe and effective treatment for recurrence of Barrett's neoplasia after RFA treatment.

Corrosive injuries (CI) become medical problems related complications include esophageal, pyloric stricture and squamous cell carcinoma, physical and quality of life. Endoscopic (ED) dilatation is primary therapy. The ultrathin endoscope-assisted method is potentially safe and useful in avoiding technical failure. Describe clinical outcomes of ED ED-related CI including successful, refractory, recurrent, and complications-related procedures. Case series study of esophageal and/or pyloric stricture patients after CI who underwent dilatation at Soetomo General Hospital (July 2018 - July 2022). One - biweekly ED using Through The Scope (TTS) balloon or Savary Bougie dilator. The target diameter is 14mm. Fifteen patients with stricture-related CI. Eleven patients underwent ED with a total of 73 procedures. Mean age 31,45 years, predominantly male patients (6), suicide attempt (7), acid agent (9), located at esophagus (3), pylorus (3), or both (5). Number of esophageal dilatation to achieve the target of 14 mm was 1-2 and 2-15 procedures for simple and complex stricture. Five esophageal strictures were successfully dilated but 2 patients were recurrent and 3 cases were refractory to ED. Pyloric dilatation resulted in a lower success rate. Recurrent and refractory cases were 5 and 3 patients respectively. ED with ultrathin endoscope method is useful for traversing guidewire during ED. Ongoing inflammation and fibrosis were linked to recurrent and refractory stricture.

BACKGROUND: Endoscopic submucosal dissection (ESD) can be performed for superficial esophageal cancer. However, performing ESD for superficial esophageal cancer on a previous endoscopic resection scar may be difficult. METHODS: We compared the outcomes between ESD for superficial esophageal cancers on previous endoscopic resection scar (group A) and that for naïve lesions (group B). The study included outcomes of ESD, cumulative incidence of local failure, and predictors of the occurrence of local failure in ESD patients with squamous cell carcinoma (SCC). The outcome variables evaluated were en bloc resection rates, procedure times, adverse events, and overall survival rates. RESULTS: Overall, 220 lesions were extracted (groups A and B: 23 and 197 lesions, respectively). In groups A and B, the complete resection rates were 60.9 and 92.9% (P < 0.001), and the mean procedure times were 79 and 68 min (P = 0.15), respectively. The perforation rates in groups A and B were 4.3 and 1% (P = 0.28). The 1-year cumulative local failure rates were 22 and 1% (P < 0.001), respectively. In the multivariate Cox proportional hazards analysis, superficial esophageal SCC on a previous endoscopic resection scar was a strong predictor of local failure (hazard ratio = 21.95 [3.99-120.80], P < 0.001). The 3-year overall survival rates in groups A and B were 95 and 93% (P = 0.99), respectively. CONCLUSIONS: Repeated ESD on scar is an option for treating superficial esophageal SCC with an acceptable rate of adverse events. Because of the low complete resection rate and high local failure compared with conventional ESD, strict endoscopic follow-up is required after repeated esophageal ESD.

BACKGROUND & AIMS: Follow-up (FU) strategies after endoscopic eradication therapy (EET) for Barrett's neoplasia do not consider the risk of mortality from causes other than esophageal adenocarcinoma (EAC). We aimed to evaluate this risk during long-term FU, and to assess whether the Charlson Comorbidity Index (CCI) can predict mortality. METHODS: We included all patients with successful EET from the nationwide Barrett registry in the Netherlands. Data were merged with National Statistics for accurate mortality data. We evaluated annual mortality rates (AMRs, per 1000 person-years) and standardized mortality ratio for other-cause mortality. Performance of the CCI was evaluated by discrimination and calibration. RESULTS: We included 1154 patients with a mean age of 64 years (±9). During median 59 months (p25-p75 37-91; total 6375 person-years), 154 patients (13%) died from other causes than EAC (AMR, 24.1; 95% CI, 20.5-28.2), most commonly non-EAC cancers (n = 58), cardiovascular (n = 31), or pulmonary diseases (n = 26). Four patients died from recurrent EAC (AMR, 0.5; 95% CI, 0.1-1.4). Compared with the general Dutch population, mortality was significantly increased for patients in the lowest 3 age quartiles (ie, age <71 years). Validation of CCI in our population showed good discrimination (Concordance statistic, 0.78; 95% CI, 0.72-0.84) and fair calibration. CONCLUSION: The other-cause mortality risk after successful EET was more than 40 times higher (48; 95% CI, 15-99) than the risk of EAC-related mortality. Our findings reveal that younger post-EET patients exhibit a significantly reduced life expectancy when compared with the general population. Furthermore, they emphasize the strong predictive ability of CCI for long-term mortality after EET. This straightforward scoring system can inform decisions regarding personalized FU, including appropriate cessation timing. (NL7039).

Background and study aims: Peroral endoscopic myotomy (POEM) is the preferred technique for the treatment of esophageal motility disorders and is less invasive than surgery. This study was performed to compare two university centers in the practice of POEM, in terms of efficacy and adverse events, for the treatment of esophageal motility disorder. Patients and methods: Retrospective comparative study of patients undergoing a POEM between September 2020 and December 2022 from the University Hospital of Liège (Belgium) and Besançon (France). The clinical success was defined by an Eckardt score ≤ 3 after the procedure. Results: Fifty-five patients were included. In both centers, 87,3% of the patients had achalasia (mostly type II), and 12,7% had another esophageal motility disorder. The use of antibiotic prophylaxis was systematic in Liège center but not in Besançon center (100% and 9.1% respectively). The mean value of the post-operative Eckardt score was 1.55± 2.48 in both center with 93.2% of patients with a score ≤ 3 (92% in Besançon and 94.74% in Liège). The rate of adverse event was generally low. There were two minor adverse events more frequent in Liège, clinical capnomediastinum and pain at day one, but they were managed with conservative treatment. Only 7.3% of the total patients had an infectious phenomenon that did not correlate with the use of antibiotic prophylaxis. Conclusion: The post-operative Eckardt score and the adverse event rate were comparable between the university centers. This study confirmed that POEM is a safe and effective technique. It also showed that using an antibiotic prophylaxis does not influence the development of infectious adverse events.
