RESUMEN
BACKGROUND & AIMS: Esophageal strictures are a leading cause of dysphagia, but data regarding the epidemiology of esophageal strictures are limited. This study aimed to investigate the prevalence, health care utilization, and financial burden of esophageal strictures in the United States. METHODS: We performed a retrospective cohort study using 2 large national insurance claims databases (MarketScan and Medicare). Using International Classification of Diseases-9 and -10 diagnostic codes, annual prevalence was calculated for both cohorts overall, and stratified by age and sex strata. Most common diagnostic and procedural codes associated with esophageal strictures were extracted and analyzed to estimate health care utilization. Direct annual medical costs of esophageal strictures were calculated. RESULTS: The annual prevalence of esophageal strictures in MarketScan in 2021 was 203.14 cases/100,000 people, whereas the annual prevalence in Medicare cohort in 2017 was 1123.47 cases/100,000. Although rates were relatively stable over time, esophageal stricture prevalence increased with advancing age. No prevalence differences were noticed between males and females. Gastroesophageal reflux disease/erosive esophagitis was the top diagnostic code associated with esophageal strictures, although an increase in the proportion of eosinophilic esophagitis codes was noted over time. Esophageal dilation codes were present in â¼50% of stricture cases. The total health care costs associated with esophageal strictures were estimated at $1.39 billion in 2017. CONCLUSIONS: Esophageal strictures are common, affecting between 1/100 and 1/1000 patients in the United States, with the highest rates seen in patients aged 75 years and older. Accordingly, strictures have a significant financial burden on the health care system, with costs greater than $1 billion annually.

BACKGROUND: Benign anastomotic stricture is a recognized complication following esophagectomy. Laparoscopic gastric ischemic preconditioning (LGIP) prior to esophagectomy has been associated with decreased anastomotic leak rates; however, its effect on stricture and the need for subsequent endoscopic intervention is not well studied. METHODS: This was a case-control study at an academic medical center using consecutive patients undergoing oncologic esophagectomies (July 2012-July 2022). Our institution initiated an LGIP protocol on 1 January 2021. The primary outcome was the occurrence of stricture within 1 year of esophagectomy, while secondary outcomes were stricture severity and frequency of interventions within the 6 months following stricture. Bivariable comparisons were performed using Chi-square, Fisher's exact, or Mann-Whitney U tests. Multivariable regression controlling for confounders was performed to generate risk-adjust odds ratios and to identify the independent effect of LGIP. RESULTS: Of 253 esophagectomies, 42 (16.6%) underwent LGIP prior to esophagectomy. There were 45 (17.7%) anastomotic strictures requiring endoscopic intervention, including three patients who underwent LGIP and 42 who did not. Median time to stricture was 144 days. Those who underwent LGIP were significantly less likely to develop anastomotic stricture (7.1% vs. 19.9%; p = 0.048). After controlling for confounders, this difference was no longer significant (odds ratio 0.46, 95% confidence interval 0.14-1.82; p = 0.29). Of those who developed stricture, there was a trend toward less severe strictures and decreased need for endoscopic dilation in the LGIP group (all p < 0.20). CONCLUSION: LGIP may reduce the rate and severity of symptomatic anastomotic stricture following esophagectomy. A multi-institutional trial evaluating the effect of LGIP on stricture and other anastomotic complications is warranted.

BACKGROUND AND AIMS: There is a high incidence of stricture after endoscopic submucosal dissection (ESD) for cervical esophageal cancer. We aimed to elucidate the risk factors for stricture and evaluate the efficacy of steroid injection for stricture prevention in the cervical esophagus. METHODS: We retrospectively analyzed 100 patients who underwent ESD for cervical esophageal cancer to: (1) identify the factors associated with stricture among patients who did not receive steroid injection; (2) compare the incidence of stricture between patients with and without steroid injection. RESULTS: Among 48 patients who did not receive steroid injection, there were significant differences in tumor size (P = .026), resection time (P = .028), and circumferential extent of the mucosal defect (P = .005) between patients with stricture (n = 5) and without stricture (n = 43). Compared with patients without steroid injection, patients with steroid injection had a significantly lower incidence of stricture when the post-ESD mucosal defect was < 3/4 and ≥ 1/2 (40% versus 8%, P = .039). As for the patients with a post-ESD mucosal defect of ≥ 3/4 (n = 13), local steroid injection was performed for all the patients, and 6 patients (46%) developed stricture. CONCLUSIONS: Patients who underwent ≥ 1/2 circumferential resection were at high risk of cervical esophageal stricture. Steroid injection had a stricture-prevention effect in patients with < 3/4 and ≥ 1/2 circumferential resection, but seemed to be insufficient in preventing stricture in patients with ≥ 3/4 circumferential resection.
RESUMEN
BACKGROUND AND AIMS: Endoscopic submucosal dissection (ESD) is the standard therapy for superficial esophageal cancer (SEC) presently. However, postoperative mucosal defects often lead to esophageal stricture. Although steroid application is effective prophylaxis, the efficacy and safety of various steroid administration modes remain unclear. Thus, this study aimed to evaluate the efficacy and safety of different steroid administrations for SEC patients post-ESD. METHODS: A search for relevant studies was conducted on China National Knowledge Infrastructure, Wanfang Database, PubMed, Embase, and Web of Science up to March 25, 2024. Treatment strategies were categorized into four groups: no prevention as control (CON), steroid injection (SI), oral steroids (OS), and SI combined with OS (SI+OS). Comparative meta-analysis was conducted to assess outcomes, including postoperative esophageal stricture rate and the number of endoscopic balloon dilatation (EBD) sessions required after stricture. RESULTS: A total of 25 studies, involving 1555 patients, were included. The SUCRA rankings were as follows: SI+OS (98.9%) > OS (59.9%) > SI (41.2%) > CON (0.0%) in preventing postoperative esophageal stricture rate, and OS (76.9%) > SI+OS (62.1%) > SI (61.0%) > CON (0.0%) in the number of EBD sessions required. Forest plot results indicated that compared with the non-steroid group, steroid interventions were associated with lower rates of postoperative stricture and fewer EBD sessions. Additionally, SI+OS was superior to SI or OS alone in preventing stricture, with no significant differences observed between different steroid administrations in terms of EBD sessions. The incidence of adverse reactions was less than 10% for all interventions, mostly mild and resolvable upon discontinuation. CONCLUSION: This study suggests that combined administration appears preferable for preventing esophageal stricture in patients post-ESD, and steroids could enhance stricture prognosis. However, due to the lack of large-sample RCT studies comparing different steroid administrations, more high-quality research is necessary to confirm these findings in the future.
RESUMEN
BACKGROUND: Patients with benign esophageal strictures may not maintain a response to endoscopic dilation, stenting, incisional or injectional therapies. For patients with these refractory esophageal strictures, esophageal self-dilation therapy (ESDT), performed to maintain luminal patency, may provide persistent symptomatic benefit while reducing patients' reliance on healthcare services and the risk associated with repeated endoscopic procedures. AIMS: The aim of this study was to evaluate the efficacy and safety of EDST in a randomized controlled trial and prospective observational study. METHODS: Twenty-five patients with refractory benign esophageal strictures were recruited at two esophageal clinics between November 2018 and June 2021. Twelve patients participated in the randomized trial and 13 in the prospective observational study. The number of endoscopic dilations, impact of therapy on dysphagia, adverse events, and complications were recorded. RESULTS: In the randomized study, 50% of patients performing ESDT and 100% of controls required endoscopic dilation during follow-up (P = 0.02). In the observational study, the median (IQR) number of endoscopic dilations fell from 7 [7-10] in the 6 months prior to commencing ESDT to 1 [0-2] in the 6 months after (P < 0.0001). Most patients (22/25) were able to learn self-dilation. Few serious adverse events were noted. Dysphagia severity remained unchanged or improved. CONCLUSIONS: ESDT appears to be a safe effective therapy for benign esophageal strictures refractory to endoscopic treatment. CLINICAL TRIAL NUMBER: NCT03738566.

BACKGROUND: Endoscopic submucosal dissection (ESD) is the current standard treatment for early-stage esophageal neoplasms. However, the postoperative esophageal stricture after extensive mucosal dissection remains a severe challenge with limited effective treatments available. In this study, we introduced a chitosan/gelatin (ChGel) sponge encapsulating the adipose mesenchymal stem cells (ADMSCs)-derived exosomes (ChGelMSC-Exo) for the prevention of esophageal stenosis after ESD in a porcine model. RESULTS: Pigs were randomly assigned into (1) ChGelMSC-Exo treatment group, (2) ChGelPBS group, and (3) the controls. Exosome treatments were applied immediately on the day after ESD as well as on day 7. Exosome components crucial for wound healing were investigated by liquid chromatography-tandem mass spectrometry (LC-MS/MS) and small RNA sequencing. ChGelMSC-Exo treatment significantly reduced mucosal contraction on day 21, with less fiber accumulation and inflammatory infiltration, and enhanced angiogenesis when compared with the control and ChGelPBS groups. The anti-fibrotic effects following MSC-Exo treatment were further found to be associated with the anti-inflammatory M2 polarization of the resident macrophages, especially within the M2b subset characterized by the reduced TGFß1 secretion, which sufficiently inhibited inflammation and prevented the activation of myofibroblast with less collagen production at the early stage after ESD. Moreover, the abundant expression of exosomal MFGE8 was identified to be involved in the transition of the M2b-macrophage subset through the activation of MFGE8/STAT3/Arg1 axis. CONCLUSIONS: Our study demonstrates that exosomal MFGE8 significantly promotes the polarization of the M2b-macrophage subset, consequently reducing collagen deposition. These findings suggest a promising potential for MSC-Exo therapy in preventing the development of esophageal stricture after near-circumferential ESD.

Introduction: Pediatric upper gastrointestinal (UGI) endoscopy is an important procedure in the management of gastrointestinal pathologies. Conventionally, it has been the forte of medical gastroenterologists. However, unlike adults, the availability of pediatric gastroenterologists is limited, especially during emergency hours. We present our early experience of UGI endoscopy done by the department of pediatric surgery. Aims: The aim of this study was to study the feasibility and benefits of UGI endoscopy by pediatric surgeons. Materials and Methods: A retrospective descriptive study was carried out by the department of pediatric surgery of a tertiary-level medical college, from January 2017 to January 2022. Data were collected from electronic and physical medical records. Parameters included age, gender, indication for endoscopy, and procedures done endoscopically or based on endoscopic findings and complications. Results: One hundred and thirty endoscopies were done in 95 patients aged 1-16 years, from January 2017 to January 2022. The most common indication for UGI endoscopy was esophageal stricture (71 procedures in 41 patients), followed by UGI foreign body (18 cases). All other indications were mostly diagnostic, other than four patients with achalasia. Thirty of these patients underwent UGI endoscopy as an emergency procedure. Seventeen patients were followed through or had added procedures, with UGI endoscopy. There was one perforation when dilating an esophageal stricture who responded to conservative management. Conclusion: UGI endoscopy is a valuable diagnostic and therapeutic procedure, which can be performed by pediatric surgeons after necessary training. It supplements decision-making in management, avoids waste of time in referring, avoids additional anesthesia, and is valuable in emergencies.
RESUMEN
Eosinophilic esophagitis (EoE) is a relatively recently identified but now frequently encountered antigen/immune-mediated disease which places significant burden on patients and the healthcare system. With its growing prevalence and recognition by healthcare providers in multiple disciplines, substantial progress has been made regarding the diagnostic criteria, clinical evaluation, tools for disease assessment, and immune pathways related to pathogenesis. Current treatment goals focus on the amelioration of inflammation and prevention of remodeling consequences using proton pump inhibitors, swallowed topical steroids, elimination diets, and esophageal dilation. Ongoing research holds promise for more efficacious and targeted therapies as well as a personalized approach to the care of patients with EoE.

BACKGROUND AND OBJECTIVES: Esophageal stricture is a troublesome adverse effect of endoscopic submucosal dissection (ESD) for early esophageal cancer. However, risk factors of post-ESD esophageal stricture formation are incomprehensive. This study aimed to conduct a comprehensive analysis of independent risk factors and provide predictive tools. METHODS: Patients who underwent ESD for early esophageal cancer between 2014 and 2021 at the Beijing Friendship Hospital, Capital Medical University, were recruited. A nomogram and risk classification system was established based on Cox proportional hazards analyses and validated using the concordance index (C-index), calibration curves, decision curve analysis (DCA), and Kaplan-Meier (K-M) curves. RESULTS: Stricture formed in 36 patients, while stricture was not observed in the remaining 112 patients. Operative time (odds ratio [OR]: 1.01; 95% confidence interval [CI]: 1.00-1.01; p < 0.01); lesions >3/4 circumferential range of esophagus (OR: 3.82; 95% CI: 1.90-7.66; p < 0.01), and tumor infiltration to the mucosal lamina propria (m2) or deeper (OR: 2.40; 95% CI: 1.24-4.66; p = 0.01) were independent predictive factors for post-ESD esophageal stricture. The nomogram and risk classification system was developed and validated with 0.79 C-index, good calibration curves, good DCA results, and good K-M curves. CONCLUSIONS: We developed a nomogram and risk stratification system to predict post-ESD esophageal stricture using three independent risk factors.

Esophageal stricture is a common complication after endoscopic submucosal dissection (ESD) for superficial esophageal cancer and precancerous lesions, we intend to investigate the independent risk factors of esophageal stricture after ESD by adding the data of included living habits, established a nomogram model to predict the risk of esophageal stricture, and verified it by external data. The clinical data and living habits of patients with early esophageal cancer and precancerous lesions who underwent ESD in the Affiliated Hospital of North Sichuan Medical College and Langzhong People's Hospital from March 2017 to August 2021 were retrospectively collected. The data collected from the two hospitals were used as the development group (n = 256) and the validation group (n = 105), respectively. Univariate and multivariate logistic regression analyses were used to determine independent risk factors for esophageal stricture after ESD and establish a nomogram model for the development group. The prediction performance of the nomogram model is internally and externally verified by calculating C-Index and plotting the receiver operating characteristic curve (ROC) and calibration curve, respectively. The results showed that Age, drinking water temperature, neutrophil-lymphocyte ratio, the extent of esophageal mucosal defect, longitudinal diameter of resected mucosa, and depth of tissue invasion (P < 0.05) were independent risk factors for esophageal stricture after ESD. The C-Index of the development group and validation group was 0.925 and 0.861, respectively. The ROC curve and area under the curve (AUC) of the two groups suggested that the discrimination and prediction performance of the model were good. The two groups of calibration curves are consistent and almost overlap with the ideal calibration curve, indicating that the predicted results of this model are in good agreement with the actual observed results. In conclusion, this nomogram model has a high accuracy for predicting the risk of esophageal stricture after ESD, providing a theoretical basis for reducing or avoiding esophageal stricture and guiding clinical practice.

OBJECTIVES: Corrosive substance ingestion in children represents a significant public health issue due to its long-term health sequelae. Esophageal stricture, main complication of this dangerous condition, is treated by pneumatic dilation and eventually by esophageal replacement. We aimed, through this study, to report the outcomes of esophageal pneumatic dilation complicating corrosive substance ingestion in children in a developing country. METHODS: This cross-sectional study was performed on the population of pediatric patients with caustic esophageal stenosis between January 2005 and December 2020. All patients underwent pneumatic balloon dilation. A logistic regression model was built to predict the probability of the occurrence of the event (success/failure) of the dilation. The ROC curve is used to evaluate the performance of the logistic regression model to discriminate between positive and negative values of the dependent variable. RESULTS: The success rate of pneumatic balloon dilation was 80.4%. The median duration of overall management was 11 months. The severity of caustic stricture observed during endoscopy was significantly linked to worse outcomes (p = 0.001). Multivariate analysis indicated that the severity of stenosis and the number of dilation sessions were independent risk factors for failure of dilation. ROC curve analysis showed that the area under the curve was 71.7%. A Cut-Off point value of 7 provided the best sensitivity and specificity. CONCLUSION: Pneumatic balloon dilation has been proven to be efficacious in infants with caustic esophageal stricture. Pediatric surgeons should take into account factors to promptly switch to replacement surgery and avoid unnecessary and time-consuming serial dilations.

BACKGROUND: Controlled radial expansion (CRE) balloon dilators are traditionally used to dilate esophageal strictures during an esophagogastroduodenoscopy (EGD). EndoFLIP is a diagnostic tool used during an EGD to measure important parameters of the gastrointestinal lumen, capable of assessing treatment before and after dilation. EsoFLIP is a related device that combines a balloon dilator with high-resolution impedance planimetry to provide some of the luminal parameters in real time during dilation. We sought to compare procedure time, fluoroscopy time, and safety profile of esophageal dilation using either CRE balloon dilation combined with EndoFLIP (E + CRE) versus EsoFLIP alone. METHODS: A single-center retrospective review was performed to identify patients ≤ 21 years of age who underwent an EGD with biopsy and esophageal stricture dilation using E + CRE or EsoFLIP between October 2017 and May 2022. RESULTS: Twenty-nine EGDs with esophageal stricture dilation were performed in 23 patients (19 E + CRE and 10 EsoFLIP). The two groups did not differ in age, gender, race, chief complaint, type of esophageal stricture, or history of prior gastrointestinal procedures (all p > 0.05). The most common medical history in the E + CRE and EsoFLIP groups were eosinophilic esophagitis and epidermolysis bullosa, respectively. Median procedures times were shorter in the EsoFLIP cohort compared to E + CRE balloon dilation (40.5 min [IQR 23-57 min] for the EsoFLIP group; 64 min [IQR 51-77 min] for the E + CRE group; p < 0.01). Median fluoroscopy times were also shorter for patients who underwent EsoFLIP (0.16 min [IQR 0-0.30 min] for EsoFLIP dilation; 0.30 min [IQR 0.23-0.55] for the E + CRE group; p = 0.003). There were no complications or unplanned hospitalizations in either group. CONCLUSION: EsoFLIP dilation of esophageal strictures was faster and required less fluoroscopy than CRE balloon dilation combined with EndoFLIP in children, while being equally as safe. Prospective studies are needed to further compare the two modalities.

BACKGROUND: Esophageal stricture is a major complication after esophageal endoscopic submucosal dissection (ESD) and when the mucosal defect exceeds 3/4 of the circumference. Various preventive methods have been reported to prevent stenosis. However, in the case of circumferential ESD, there is no way to prevent luminal stenosis effectively. This retrospective study aimed to evaluate the efficacy of 20-French nasogastric tubes (NGT) combined with oral steroids for the prevention of esophageal stricture after endoscopic submucosal dissection. METHODS: Between January 2012 and December 2021, we enrolled 57 patients with post-ESD mucosal defects exceeding 3/4 of the esophageal circumference. Of them, the initial seven patients received oral steroid therapy and the subsequent 50 patients received 20-French NGT placements combined with oral steroid therapy. We retrospectively evaluated the rates of strictures and refractory strictures and explored risk factors for strictures with 20-French NGT. RESULTS: The overall esophageal stricture rate was 42.1% (24/57). In the noncircumferential group, the esophageal stricture rate in patients with only oral steroid to prevent esophageal stricture was 85.7% (6/7), while the esophageal stricture rate was only 4.3% (1/23) in those with 20-French NGT placements and oral steroid. All 27 patients with whole-circumferential resection received 20-French NGT placements. The stricture rate was 63.0% (17/27), and the refractory stricture rate was 17.6% (3/27). CONCLUSION: Using a 20-French NGT placement combined with oral steroid administration is an easy and safe alternative to prevent esophageal stricture after ESD, especially for patients with noncircumferential mucosal defects. Further studies are needed to develop an effective stricture prevention method for post-ESD whole-circumferential mucosal defects of the esophagus.

BACKGROUND: Gastroesophageal reflux disease (GERD) is often associated with esophageal stricture, particularly benign esophageal stricture. We aimed to evaluate the effects of balloon catheter dilation (BD) combined with laparoscopic fundoplication (LF) surgery and proton pump inhibitors (PPIs) in patients with reflux-induced esophageal strictures. METHODS: We retrospectively analyzed 116 patients with reflux-induced benign esophageal strictures who underwent balloon dilatation therapy combined with PPIs (BD-PPIs group, n = 58) and balloon dilatation combined with LF (BD-LF group, n = 58). Patients were followed up for 24 months. The outcomes of the patients were monitored, including clinical success, symptom improvement, adverse events, and the frequency of esophagitis. RESULTS: At the latest follow-up, the rate of clinical success was higher in BD-LF group than in BD-PPIs group (80.4% vs. 57.7%, P = 0.011). The patients in the BD-PPIs group required more dilation sessions to achieve successful dilation, as compared to those in the BD-LF group (2.1 ± 1.2 vs. 0.7 ± 0.8, P < 0.001). The DeMeester score, number of reflux episodes for which pH was < 4, and lower esophageal sphincter pressure were significantly better in the BD-LF group than in the BD-PPIs group (all P < 0.001). The incidence of reflux esophagitis was higher in the BD-PPIs group than in the BD-LF group, at 24 months (58.8% vs. 18.2%, P = 0.003). CONCLUSIONS: Balloon dilatation with concomitant LF is effective and safe for esophageal stricture secondary to GERD. Moreover, antireflux surgery techniques, such as Nissen or Toupet procedure, should be added for reflux-induced benign esophageal stricture.

BACKGROUND: The self-help inflatable balloon (SHIB) and autologous skin-grafting surgery (ASGS) were used to prevent stricture after esophageal complete circular endoscopic submucosal dissection (cESD) with promising clinical results. We aim to evaluate which method is more suitable for patients who underwent esophageal cESD. METHODS: From October 2017 to July 2021, patients whose mucosal defect length were between 30 and 100 mm after esophageal cESD were retrospectively reviewed from two prospective studies. They were enrolled once SHIB or ASGS was used as preventive methods to prevent stricture. Propensity score matching (PSM) was used to balance the baseline characteristics between the two groups. Comparisons were made between the two groups, including operation time, the longitudinal length of ulceration, fasting time, hospitalization days, and the incidence of stricture. RESULTS: A total of 41 patients who met the inclusion criteria were enrolled in the study. The numbers of patients in SHIB group and ASGS group were 25 and 16, respectively. Fifteen patients in each group were selected after performing PSM. The basic baseline characteristics were comparable between the two groups. The stricture rates were 20% (3/15) in SHIB group and 40% (6/15) in ASGS group, while the difference was not statistically significant (p = 0.427). The SHIB group showed significantly shorter operation time, shorter hospitalization days, lower cost, and longer removing balloon/stent time compared with ASGS group (p < 0.001). Comparison of relevant stricture factors between the stricture group and non-stricture group revealed that longer longitudinal length of ulceration (> 60 mm) accounted for a higher proportion in stricture groups (p = 0.035). CONCLUSION: Both the SHIB and ASGS had high efficacy and safety in preventing strictures in patients with mucosal defects no longer than 100 mm in length after esophageal cESD. The longitudinal length of ulceration > 60 mm was the independent factor for predicting stricture.

Ingestion of caustic agents by children is a serious health issue that can affect the patient for the rest of his life. The role of sucralfate in preventing stricture caused by caustic agents is controversial, and limited studies have been conducted in this field. We aimed to investigate the effect of sucralfate on preventing esophageal stricture in children. Sixty children with mean age of 36.69 ± 20.50 months and grade II B esophageal burns due to ingestion of caustic agents were enrolled in the study. In the intervention group, in addition to the usual treatment, sucralfate was administered orally at a dose of 80 mg/kg every 2 h for 3 days. For the control group, only the usual treatment was prescribed. Stricture development was compared between groups based on endoscopic and radiologic findings. Of the 60 patients enrolled in the study, 53 were examined. The incidence of esophageal stricture in the intervention group was significantly lower than in the control group (37% versus 67%, P-value = 0.042). In addition, the odds of esophageal stricture after sucralfate intervention was significantly reduced after adjustment for potential confounders (OR = 0.198, P-value = 0.031). Conclusions: The results of this study showed that sucralfate may reduce the development of esophageal stricture in children when used to manage IIB esophageal burns due to ingestion of caustic agents. What is Known: ⢠Ingestion of caustic agents by children is a serious health issue that can affect the patient for the rest of his life. ⢠The role of sucralfate in preventing stricture caused by caustic agents is controversial and limited studies have been conducted in this field. What is New: ⢠It seems that sucralfate significantly reduces the incidence of esophageal stricture following the ingestion of caustic agents in children compared to the control group. ⢠We believe that the prognosis may be improved and the risk of stricture formation may be reduced with high doses of sucralfate therapy in grade IIB esophageal injury.

Children with esophageal atresia (EA) may require enteral tube feedings in infancy and a subset experience ongoing feeding difficulties and enteral tube dependence. Predictors of enteral tube dependence have never been systematically explored in this population. We hypothesized that enteral tube dependence is multifactorial in nature, with likely important contributions from anastomotic stricture. Cross-sectional clinical, feeding, and endoscopic data were extracted from a prospectively collected database of endoscopies performed in EA patients between August 2019 and August 2021 at an international referral center for EA management. Clinical factors known or hypothesized to contribute to esophageal dysphagia, oropharyngeal dysphagia, or other difficulties in meeting caloric needs were incorporated into regression models for statistical analysis. Significant predictors of enteral tube dependence were statistically identified. Three-hundred thirty children with EA were eligible for analysis. Ninety-seven were dependent on enteral tube feeds. Younger age, lower weight Z scores, long gap atresia, neurodevelopmental risk factor(s), significant cardiac disease, vocal fold movement impairment, and smaller esophageal anastomotic diameter were significantly associated with enteral tube dependence in univariate analyses; only weight Z scores, vocal fold movement impairment, and anastomotic diameter retained significance in a multivariable logistic regression model. In the current study, anastomotic stricture is the only potentially modifiable significant predictor of enteral tube dependence that is identified.

Whether obesity is protective against progression of EoE is unknown. The aim of this study was to assess factors that alter the progression of EoE and determine if BMI is correlated with reduced disease severity. In this retrospective analysis of the Department of Veterans Affairs electronic health records, patients with EoE who received at least one dilation were identified using ICD and CPT codes. Kaplan-Meier curves determined the relationship between BMI and time to second esophageal dilation as a measurement of severity of disease. Cox proportional hazards models assessed the risk of second dilation adjusted for potential confounders. Of 2890 patients with EoE and at least one dilation, 40% were obese (n = 1165). There were no clinically significant differences in demographics between obese and non-obese patients. Non-obese patients were more likely to be smokers and had a higher mean average of the number of dilation visits compared to obese patients (p < 0.05). When stratified by obesity, non-obese individuals had a median time to next dilation of 6.53 years (95% CI (5.83, 7.79)) compared to 9.24 years for obese individuals (95% CI (7.40, 15.04)). When stratified by six BMI categories, median time to second dilation increased with increasing BMI. The hazard ratio of second dilation for obese individuals was 0.81 (95% CI (0.72-0.92)). EoE patients with a higher BMI were less likely to undergo a second dilation compared to those with a lower BMI. Obesity may have a protective role in EoE or severe strictures may lead to malnourishment. Further research into these possibilities is needed.

BACKGROUND/PURPOSE: Endoscopic submucosal dissection (ESD) is a minimally invasive endoscopic procedure to deal with local early esophageal neoplasm, although post-ESD esophageal stricture is a major delayed complication of esophageal ESD greatly influencing the patient's quality of life. This retrospective study was conducted to analyze the esophageal stricture after esophageal ESD while determining further treatment and outcome of stricture management. METHODS: From 2009 to 2021, we reviewed all patients who underwent ESD for esophageal squamous cell neoplasia in Kaohsiung Medical University Hospital. RESULTS: Totally, 133 patients with esophageal squamous cell neoplasm were enrolled. Among these 133 patients, 108 patients had lesions less than three-fourths in circumferential and 25 patients had lesions in excess of three-fourths circumferentially. Totally, 18 patients (13.5%) had symptomatic esophageal stricture and 17 patients (94.4%) had stricture existing over the upper or middle esophagus. The most important risk factor of esophageal stricture was the extent of resection of esophageal circumference, especially whole circumferential resection. Although oral steroid prevention medication was prescribed for high-risk patients with lesions more than three-fourth circumferential ESD, the stricture rate was still up to 40% (10/25). Endoscopic/luminal management with balloon dilation, radial incision and self-bougination achieved 83% (15/18) symptom remission. Three patients received surgical intervention with esophagectomy or jejunostomy. CONCLUSION: Esophageal stricture is frequently encountered in esophageal ESD. Aggressive preventative strategy is warranted for the high-risk group. Endoscopy/luminal management has high efficacy for post-ESD esophageal stricture.

Esophageal stricture is a narrowing of the esophageal lumen which is often characterized by impaired swallowing or dysphagia. It can be induced by inflammation, fibrosis or neoplasia which damages the mucosa and/or submucosa of the esophagus. Corrosive substance ingestion is one of the major causes of esophageal stricture, particularly in children and young adults. For instance, accidental ingestion or attempted suicide with corrosive household products is not uncommon. Gasoline is a liquid mixture of aliphatic hydrocarbons derived from the fractional distillation of petroleum, which is then combined with additives such as isooctane and aromatic hydrocarbons (e.g., toluene and benzene). Gasoline also contains several other additives including ethanol, methanol and formaldehyde, which make it a corrosive agent. Interestingly, to the best of our knowledge, the incidence of esophageal stricture caused by chronic gasoline ingestion has not been reported. In this paper, we report the case of a patient with dysphagia due to complex esophageal stricture due to chronic gasoline ingestion who underwent a series of esophago-gastro-duodenoscopy (EGD) procedures and repeated esophageal dilation.
