Endoscopic Dilatation with Ultrathin Endoscope Assisted Method for Esophageal and Pyloric Stricture related Corrosive Injury: 4 Years Case Series Study.

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.

Peroral endoscopic myotomy: a two-center retrospective study of practice and adverse events.

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.

The occurrence and development mechanisms of esophageal stricture: state of the art review.

BACKGROUND: Esophageal strictures significantly impair patient quality of life and present a therapeutic challenge, particularly due to the high recurrence post-ESD/EMR. Current treatments manage symptoms rather than addressing the disease's etiology. This review concentrates on the mechanisms of esophageal stricture formation and recurrence, seeking to highlight areas for potential therapeutic intervention. METHODS: A literature search was conducted through PUBMED using search terms: esophageal stricture, mucosal resection, submucosal dissection. Relevant articles were identified through manual review with reference lists reviewed for additional articles. RESULTS: Preclinical studies and data from animal studies suggest that the mechanisms that may lead to esophageal stricture include overdifferentiation of fibroblasts, inflammatory response that is not healed in time, impaired epithelial barrier function, and multimethod factors leading to it. Dysfunction of the epithelial barrier may be the initiating mechanism for esophageal stricture. Achieving perfect in-epithelialization by tissue-engineered fabrication of cell patches has been shown to be effective in the treatment and prevention of esophageal strictures. CONCLUSION: The development of esophageal stricture involves three stages: structural damage to the esophageal epithelial barrier (EEB), chronic inflammation, and severe fibrosis, in which dysfunction or damage to the EEB is the initiating mechanism leading to esophageal stricture. Re-epithelialization is essential for the treatment and prevention of esophageal stricture. This information will help clinicians or scientists to develop effective techniques to treat esophageal stricture in the future.

Clinical outcomes of endoscopic submucosal dissection for superficial esophageal neoplasia in close proximity to esophageal varices: a multicenter international experience.

BACKGROUND : There are limited data on the feasibility of endoscopic submucosal dissection (ESD) for superficial esophageal neoplasia (SEN) located at or adjacent to esophageal varices. We aimed to evaluate the outcomes of ESD in these patients. METHODS: This multicenter retrospective study included cirrhotic patients with a history of esophageal varices with SEN located at or adjacent to the esophageal varices who underwent ESD. RESULTS: 23 patients with SEN (median lesion size 30 mm; 16 squamous cell neoplasia and seven Barrett's esophagus-related neoplasia) were included. The majority were Child-Pugh B (57 %) and had small esophageal varices (87 %). En bloc, R0, and curative resections were achieved in 22 (96 %), 21 (91 %), and 19 (83 %) of patients, respectively. Severe intraprocedural bleeding (n = 1) and delayed bleeding (n = 1) were successfully treated endoscopically. No delayed perforation, hepatic decompensation, or deaths were observed. During a median (interquartile range) follow-up of 36 (22-55) months, one case of local recurrence occurred after noncurative resection. CONCLUSION: ESD is feasible and effective for SEN located at or adjacent to esophageal varices in cirrhotic patients. Albeit, the majority of the esophageal varices in our study were small in size, when expertise is available, ESD should be considered as a viable option for such patients.

Diverticular peroral endoscopic myotomy (D-POEM) for symptomatic oesophageal diverticulum: a multicentre cohort study with a minimum follow-up of 3 years.

OBJECTIVE: To evaluate the medium- and long-term outcomes of diverticular peroral endoscopic myotomy (D-POEM) for symptomatic oesophageal diverticulum. METHODS: Consecutive patients with symptomatic oesophageal diverticulum who underwent D-POEM from 1st May 2016 to 1st April 2020 in 6 centres were extracted and researched. Symptoms assessed by the modified Eckardt score were registered pre- and post-D-POEM at 1, 6, 12, 24 and 36 months. RESULTS: A total of 34 patients with Zenker's diverticulum (ZD, n = 12), mid-oesophageal diverticulum (MED, n = 12), and epiphrenic diverticulum (ED, n = 10) were included. Complete septotomy was achieved in a mean of 39.15 min, with 100% technical success. No severe intraoperative or postoperative complications were observed. Five patients exhibited subcutaneous emphysema, while 1 had mucosal injury. The mean Eckardt score was 8.59 preoperatively and 2.56 at 1 month, 2.09 at 6 months, 2.21 at 12 months, 2.15 at 24 months, and 2.21 at 36 months postoperatively. The total clinical success rates at 1, 6, 12, 24 and 36 months postoperatively were 97.1%, 97.1%, 94.1%, 91.2%, and 88.2%, respectively. With a median follow-up of 47.2 months, four patients suffered symptom relapse, with a total clinical success rate of 88.2%. A long disease duration, a high Eckardt score, and coexistence of achalasia were identified as risk factors for symptomatic recurrence by multivariable Cox analysis. CONCLUSIONS: D-POEM is an effective and durable treatment for patients with symptomatic oesophageal diverticulum.

Clinical Value of Endoscopic Esophageal Screening in Head and Neck Squamous Cell Carcinoma Patients.

OBJECTIVE: To investigate the clinical benefit of routine esophageal screening in newly diagnosed head and neck squamous cell carcinoma (HNSCC) patients. STUDY DESIGN: Retrospective cohort study. SETTING: Tertiary medical center. METHODS: This retrospective study selected newly diagnosed HNSCC patients from the Chang Gung Research Database between January 2007 and December 2019. Patients who underwent endoscopic esophageal examinations within 2 months of the initial diagnosis of HNSCC were included in the screening group. The clinical outcomes of the screening and nonscreening groups were analyzed. RESULTS: In total, 13,627 HNSCC patients were included, comprising 1032 females and 12,640 males (mean age 55.0 years), and the esophageal screening group included 7033 (51.4%) patients. The prevalence rate of esophageal tumors was 4.5%. Hypopharyngeal cancer patients were the most likely to have (13.4%) second primary esophageal tumors. The American Joint Committee on Cancer stage of the esophageal tumor was lower in the esophageal screening group than in the nonesophageal screening group. The oral, oropharyngeal, and hypopharyngeal cancer patients in the esophageal screening group had better survival outcomes than their counterparts in the nonesophageal screening group. CONCLUSION: Endoscopic esophageal screening of newly diagnosed HNSCC patients can detect esophageal tumors at an early stage and improve overall survival. Esophageal screening could be a routine survey in HNSCC patients, particularly those with lifestyle risk factors and in countries with a high prevalence of esophageal cancer.

How should extra-large Lugol-unstained lesions of the esophagus be treated? Results from a population-based cohort study.

BACKGROUND: Current guidelines recommend only severe dysplasia and above (SDA) lesions of the esophageal squamous epithelium for clinical intervention. However, the histopathologic diagnosis derived from tissue biopsies may be subject to underestimation of severity. METHODS: 1073 participants from whom biopsies were taken at baseline chromoendoscopic examination in a population-based screening trial were enrolled in this study. The size of the Lugol-unstained lesions (LULs) was mainly analyzed. The outcome was defined as SDA lesions either identified at baseline screening, or during follow-up, collectively referred to as the cumulative risk of SDA. Multivariable logistic regression models were used to evaluate the cumulative risk of SDA. RESULTS: One hundred and forty-six SDA cases were identified in the study period. Participants with large LULs had a high cumulative incidence of SDA (cumulative incidence16-20mm : 55.88%; cumulative incidence>20mm : 76.92%) in the median of 7-year duration. LULs of large size were significantly associated with a higher cumulative risk of SDA, regardless of the pathologic diagnosis (adjusted OR16-20mmvs.≤5mm = 21.02, 95% CI: 7.56-58.47; adjusted OR>20mmvs.≤5mm = 33.62, 95% CI: 11.79-95.87). CONCLUSIONS: Results from this study suggest physician-patient shared decision-making regarding clinical treatment or intensive surveillance should be carried out for LULs >20 mm in the esophagus, regardless of the histologic diagnosis. For those with LULs of 16-20 mm, intensive surveillance would also best be considered.

Endoscopic dilation with bougies versus balloons in caustic esophageal strictures: 17-year experience from a tertiary care center.

INTRODUCTION: Endoscopic dilation is the preferred management strategy for caustic esophageal strictures (CES). However, the differences in outcome for different dilators are not clear. We compared the outcome of CES using bougie and balloon dilators. METHODS: Between January 2000 and December 2016, the following data of all the patients with CES were collected: demographic parameters, substance ingestion, number of strictures, number of dilations required to achieve ≥ 14 mm dilation, post-dilation recurrence, and total dilations. Patients were divided into two groups for the type of dilator, i.e., bougie or balloon. The two groups were compared for baseline parameter, technical success, short- and long-term clinical success, refractory strictures, recurrence rates, and major complications. RESULTS: Of the 189 patients (mean age 32.17 ± 12.12 years) studied, 119 (62.9%) were males. 122 (64.5%) patients underwent bougie dilation and 67 (35.5%) received balloon dilation. Technical success (90.1% vs. 68.7%, p < 0.001), short-term clinical success (65.6% vs. 46.3%, p value 0.01), and long-term clinical success (86.9% vs. 64.2%, p < 0.01) were higher for bougie dilators compared to balloon dilators. Twenty-four (12.7%) patients developed adverse events which were similar for two groups. On multivariate analysis, use of bougie dilators (aOR 4.868, 95% CI 1.027-23.079), short-term clinical success (aOR 5.785, 95% CI 1.203-27.825), and refractory strictures (aOR 0.151, 95% CI 0.033-0.690) were independent predictors of long-term clinical success. CONCLUSION: Use of bougie dilators is associated with better clinical success in patients with CES compared to balloon dilators with similar rates of adverse events.

Optimizing management for early-stage esophageal adenocarcinoma: longitudinal results from a multidisciplinary program.

BACKGROUND: The management of early-stage esophageal cancer is nuanced. A multidisciplinary approach may optimize management through selection of candidates for surgical or endoscopic therapies. The objective of this research was to examine long-term outcomes of patients with early-stage esophageal cancer who undergo treatment with endoscopic resection or surgery. METHODS: Data on patient demographics, co-morbidities, pathology results, OS and RFS were obtained for both the endoscopic resection group and esophagectomy group. Univariate analysis of OS and RFS were conducted using the Kaplan-Meier method with calculation of the log-rank test. Multivariate cox-proportional hazards models were created for OS and RFS using a hypothesis-driven approach. A multivariate logistic regression model was created to identify predictors of esophagectomy among patients undergoing initial endoscopic resection. RESULTS: A total of 111 patients were included. The median OS for the surgery group was 67.0 months compared to 74.0 months in the endoscopic resection group (log-rank p = 0.93). The median RFS for the surgery group was 109.4 months compared to 63.3 months in the endoscopic resection group (log-rank p = 0.0127). On multivariable analysis, patients undergoing endoscopic resection had significantly worse RFS (HR 2.55, 95% CI 1.09-6.00; p = 0.032), but equivalent OS (HR 1.03, 95% CI 0.46-2.32; p = 0.941), compared to patients undergoing esophagectomy. High-grade disease (OR 5.43, 95% CI 1.13-26.10; p = 0.035) and submucosal involvement (OR 7.75, 95% CI 1.90-31.40; p = 0.004) were identified as significant predictors of proceeding to esophagectomy. CONCLUSIONS: Through a multidisciplinary approach, patients with early-stage esophageal cancer achieve excellent RFS and OS. Submucosal involvement and high-grade disease place patients at increased risk for local disease recurrence; these patients may undergo endoscopic resection safely if treated with a multidisciplinary approach incorporating endoscopic surveillance and surgical consultation. Further risk-stratification models may enable better patient selection and optimization of long-term outcomes.

Per-oral endoscopic myotomy is a safe and effective treatment for Zenker's diverticulum: a retrospective multicenter study.

Zenker per-oral endoscopic myotomy (ZPOEM) has become a promising technique for Zenker's diverticulum (ZD). The aim of this study was to add to the limited body of literature evaluating the safety and efficacy of ZPOEM. A prospectively maintained database was retrospectively reviewed to identify patients who underwent ZPOEM at two separate institutions between January 2020 and January 2022. Demographics, preoperative and postoperative clinical data, intraoperative data, adverse events, and length of stay were analyzed. A total of 40 patients (mean age 72.5 years, 62.5% male) were included. Average operative time was 54.7 minutes and average length of stay was 1.1 days. There were three adverse events, and only one was related to the technical aspects of the procedure. Patients showed improvement in the Functional Oral Intake Scale (FOIS) scores at 1 month (5 vs 7, p < 0.0001). The median FOIS scores remained 7 at both 6 and 12 months, although this improvement was not statistically significant at these time intervals (p = 0.46 and 0.37, respectively). Median dysphagia scores were decreased at 1 (2.5 vs 0, p < 0.0001), 6 (2.5 vs 0, p < 0.0001), and 12 months (2.5 vs 0, p = 0.016). The number of patients reporting ≥1 symptom was also decreased at 1 (40 vs 9, p < 0.0001) and 6 months (40 vs 1, p = 0.041). Although the number of patients reporting ≥1 symptom remained consistent at 12 months, this was not statistically significant (40 vs 1, p = 0.13). ZPOEM is a safe and highly effective treatment for the management of ZD. .

Esophageal perforation etiology, outcome, and the role of surgical management - an 18-year experience of surgical cases in a referral center.

INTRODUCTION: Esophageal perforation is a surgical emergency with a high rate of morbidity and mortality. Its poor prognosis is mainly associated with previous patient-specific comorbidities and a lack of timely diagnosis and treatment. The objective of this study was to investigate the etiological factors and different surgical methods of treatment with consideration of mortality rate and comorbidities. METHOD: The present cross-sectional study was conducted on patients who underwent surgical intervention due to esophageal injury from 2002 to 2019 (18 years). Demographic and clinical characteristics along with performed surgical interventions were evaluated accordingly. RESULTS: In this study, 69 patients with a mean age of 38.8 years were evaluated, of which 45 (65.2%) cases were men. In terms of location of the perforation, the thoracic portion of the esophagus followed by the cervical and abdominal esophagus were more frequently injured with a rate of 32 (46.4%), 30 (43.5%), and 19 (27.5%) cases, respectively. Accordingly, foreign body ingestion followed by penetrating injuries were the most common causative agents leading to esophageal perforation. CONCLUSION: Obtaining the desired results from the treatment of this condition depends on factors such as patients' previous comorbidities, cause of the rupture, the location of the esophageal damage, and delay in the start of treatment. Since there is no single gold standard treatment strategy, each patient should be individually evaluated.

Repeat peroral endoscopic myotomy with simultaneous submucosal and muscle dissection as a salvage option for recurrent achalasia.

BACKGROUND: For recurrent achalasia after initial peroral endoscopic myotomy (POEM) failure, repeat POEM (Re-POEM) has been reported as a treatment option. However, severe esophageal interlayer adhesions caused by previous procedures impede the successful establishment of a submucosal tunnel and lead to aborted Re-POEM procedures. Our team previously described POEM with simultaneous submucosal and muscle dissection (POEM-SSMD) as a feasible solution for achalasia with severe interlayer adhesions. AIM: To investigate the effectiveness and safety of Re-POEM with simultaneous submucosal and muscle dissection (Re-POEM-SSMD). METHODS: A total of 1049 patients with achalasia who underwent successful endoscopic myotomy at the Digestive Endoscopic Center of Chinese PLA General Hospital from December 2014 to May 2022 were reviewed. Patients with recurrent achalasia who experienced initial POEM clinical failure were retrospectively included in this study. The primary endpoint was retreatment clinical success, defined as an Eckardt score ≤ 3 during the postretreatment follow-up and no need for additional treatment. Procedure-related adverse events, changes in manometric lower esophageal sphincter (LES) pressure and reflux complications, as well as procedure-related parameters, were recorded. RESULTS: Sixteen patients underwent Re-POEM (9 patients) or Re-POEM-SSMD (7 patients) successfully at a median of 45.5 mo (range, 4-95 mo) after initial POEM. During a median follow-up period of 31 mo (range, 7-96 mo), clinical success (Eckardt score ≤ 3) was achieved in 8 (88.9%) and 6 (85.7%) patients after Re-POEM and Re-POEM-SSMD, respectively (P = 0.849). The median Eckardt score dropped from 4 (range, 3-8) at preretreatment to 1 (range, 0-5) at postretreatment in the Re-POEM group (P = 0.025) and from 5 (range, 2-8) to 2 (range, 0-4) in the Re-POEM-SSMD group (P < 0.001). The mean manometric LES pressure decreased from 23.78 ± 9.04 mmHg to 11.45 ± 5.37 mmHg after Re-POEM (P < 0.001) and from 26.80 ± 7.48 mmHg to 11.05 ± 4.38 mmHg after Re-POEM-SSMD (P < 0.001). No serious adverse events were recorded in both groups. CONCLUSION: In conclusion, Re-POEM-SSMD appears to be a safe and effective salvage therapy for recurrent achalasia with severe interlayer adhesions.

Esophageal dilation through bouginage or balloon catheters in children, as the treatment of benign esophageal strictures: results, considering the etiology, and the methods.

BACKGROUND: Corrosive substance ingestion, history of esophageal surgery, and reflux esophagitis are the main causes of benign esophageal strictures in children. Esophageal dilation is the first treatment option. Bougies and balloons are the most frequently used dilation tools. The literature record on esophageal dilation methods and their results is mostly composed of data gathered from adults, who differ from children in many terms, including etiology, indications, and results. This study aims to evaluate esophagial dilation in children; comparing the two mentioned modalities; and considering the impact of different diseases on dilation success. METHODS: The benign esophageal stricture cases who had undergone esophageal dilation between 2001 and 2009, at two tertiary health-care centers of a university were evaluated retrospectively with regard to stricture etiology, treatment methods, and their results. In addition, balloon and bougie dilations were compared. RESULTS: Fifty-four cases were dilated in 447 sessions. The strictures were due to corrosive ingestion or anastomoses in 72.2% of the cases. Of the dilation sessions, 52.6% were performed with Savary-Gilliard bougies, and the rest with balloon dilators. No guidewire was needed in 53.2% of the bougie sessions. Fluoroscopy was used during balloon dilation sessions as a routine part of the method, while it was needed only to check the guide location when needed during the bougie dilation sessions. The complication rates of balloon and bougie dilation sessions were 2.4% and 2.1%, respectively. The mean session length was 26.2±11.8 and 42.6±13.7 min, for bougie and balloon, respectively. Success rate was 93.7% for the balloon, while 98.2% of the bougie sessions. Balloon catheters used were disposable. CONCLUSION: Savary-Gilliard bougies have advantages over balloon catheters with less need of fluoroscopy, shorter duration of sessions, and lower cost. Both methods are equivalently safe with close complication rates.

Narrow-band imaging vs Lugol chromoendoscopy in screening for esophageal squamous cell neoplasia: a randomized trial.

INTRODUCTION: To date, there is no established optimal method for endoscopic detection of esophageal squamous cell neoplasia in high­risk individuals. OBJECTIVES: We aimed to compare the performance of narrow­band imaging (NBI) and Lugol chromoendoscopy in screening for esophageal neoplasia among patients with a history of treatment for head and neck squamous cell cancer (HNSCC). PATIENTS AND METHODS: We randomly assigned 300 patients who had completed curative treatment for HNSCC at least 1 year prior to the inclusion to undergo either NBI or Lugol endoscopy (2:1 ratio). Following white­light examination of the esophagus, the assigned imaging study was performed, and biopsies were taken from any suspicious lesions identified using NBI or Lugol chromoendoscopy. The primary end point was positive predictive value (PPV) of the biopsied lesion for a diagnosis of esophageal neoplasia (high­grade intraepithelial neoplasia [HG­IEN] or invasive esophageal squamous cell carcinoma [ESCC]). The secondary end points included the number of biopsied lesions, duration of esophagus examination, and endoscopy tolerance. RESULTS: In 294 patients included in the final analysis (NBI, n = 204; Lugol chromoendoscopy, n = 90), we diagnosed 3 ESCCs (1.02%) and 2 HG­IENs (0.68%). The PPV of NBI and Lugol chromoendoscopy in per­lesion analysis was 7.69% (95% CI, 0.94%-25.1%) and 8.11% (95% CI, 1.7%-21.9%), respectively (P >0.99). NBI outperformed Lugol chromoendoscopy in terms of the rate of patients requiring biopsy (12.75% vs 41.11%; P = 0.003), duration of esophagus examination (3.5 min vs 5.15 min; P <0.001), and endoscopy tolerance assessed on the visual analog scale (25 mm vs 36.5 mm; P = 0.002). CONCLUSIONS: With a PPV comparable to that of Lugol chromoendoscopy, but a lower number of biopsies required, shorter examination time, and better patient tolerance, NBI could be considered the primary screening method for ESCC in patients with HNSCC.

Veterans with multiple risk factors for Barrett's esophagus are infrequently evaluated with upper endoscopy.

Recent guidelines recommend screening for patients with chronic gastroesophageal reflux disease who have three or more additional risk factors for Barrett's esophagus (BE). Failure to screen high-risk individuals represents a missed opportunity in esophageal adenocarcinoma prevention and early detection. We aimed to determine the frequency of upper endoscopy and prevalence of BE and esophageal cancer in a cohort of United States veterans who possessed four or more risk factors for BE. All patients at VA New York Harbor Healthcare System with at least four risk factors for BE between 2012 and 2017 were identified. Procedure records were reviewed for upper endoscopies performed between January 2012 and December 2019. Multivariable logistic regression was used to determine risk factors associated with undergoing endoscopy and factors associated with BE and esophageal cancer. 4505 patients with at least four risk factors for BE were included. 828 patients (18.4%) underwent upper endoscopy, of which 42 (5.1%) were diagnosed with BE and 11 (1.3%) with esophageal cancer (10 adenocarcinoma; 1 squamous cell carcinoma). Among individuals who underwent upper endoscopy, risk factors associated with undergoing endoscopy included obesity (OR, 1.79; 95% CI, 1.41-2.30; P < 0.001) and chronic reflux (OR, 3.86; 95% CI, 3.04-4.90; P < 0.001). There were no individual risk factors associated with BE or BE/esophageal cancer. In this retrospective analysis of patients with 4 or more risk factors for BE, fewer than one-fifth of patients underwent upper endoscopy, supporting the need for efforts aimed at improving BE screening rates.

Peroral Endoscopic Myotomy for Achalasia in Older Adults: A Retrospective Analysis of 39 Cases with a Minimum Follow-Up of 5 Years.

Peroral endoscopic myotomy (POEM) has demonstrated favorable short-term safety and efficacy in older adults, while a comprehensive understanding of the long-term outcomes were vague. We aimed to evaluate clinical outcomes in older adults' 5-year postop after undergoing POEM to treatment achalasia. Older adults from a single hospital who received POEM between January 2010 and January 2017 were analyzed. Older persons were reached to evaluate their symptoms at present and encouraged repeat examinations for objective follow-up. The clinical success, POEM-related indicators, POEM-related adverse events, and quality of life were assessed. Thirty-nine older adults with a mean age of 70.82 ± 4.72 who underwent POEM were studied at a mean 84.23 ± 25.06 month follow-up. The preoperative diagnosis was achalasia type I in 7 older adults, achalasia type II in 26 older adults, and achalasia type III in 2 older adults. Sixteen older adults had prior treatment and 21 older adults suffered from comorbidities. The median operative time was 50 (25-120) minutes, and perioperative adverse events were recorded in four older adults. The current Eckardt scores were significantly lower than that before POEM (2.08 ± 2.12 vs. 6.58 ± 1.78, P < 0.001). Besides, long-term clinical success was gained in 66.7% of older adults. Three older adults received postop treatment for symptom recurrence. Ultimately, 80.6% of old adults expressed satisfaction with POEM, while 27.8% of older adults suffered from symptomatic reflux. In conclusion, POEM can provide symptomatic improvement in a large proportion of older adults with achalasia at 5-year postop.
