Abstract
OBJECTIVE This study aims to investigate the efficacy and safety of snare traction-assisted endoscopic submucosal dissection (ESD) for the management of circumferential superficial esophageal cancer. METHODS A total of 68 patients who underwent ESD for circumferential superficial esophageal cancer were included in this study. All the patients were divided into two groups based on whether the snare traction was used or not; the snare traction group (S-ESD, group n = 35) and the control group (C-ESD, group n = 33). RESULTS There was no significant difference in the size of the resected area between the groups [21.98 (18.30, 27.00) cm2 vs 24.00 (15.28, 30.72) cm2, P = 0.976]. The snare traction group had a shorter dissection time [92.00 (74.00, 121.00) min vs 110.00 (92.50, 137.00) min, P = 0.017] and a faster resection speed [0.28 ± 0.13 cm2/min vs 0.22 ± 0.11cm2/min, P = 0.040] compared to the control group. There were no statistically significant differences between the two groups in terms of hospital stay, cost, en bloc resection rate, R0 resection rate, curative resection rate, bleeding rate, perforation rate, stricture rate, and recurrence rate (P > 0.05). CONCLUSION Snare traction-assisted ESD is a safe and efficient approach for the treatment of circumferential superficial esophageal cancer. Its advantages includes shorter procedure so the anesthesia requirement, clear operative filed view, improved mucosal dissection efficiency, simple, and easily accessible equipment.

Abstract
BACKGROUND AND PURPOSE Endoscopic submucosal dissection (ESD) is a promising technique for superficial esophageal lesions. However, stricture is a frequent adverse complication. This study was performed to develop a precise and convenient score prediction model for esophageal strictures after ESD, and compare its efficacy with a previously published predictive model. METHODS This study enrolled clinical data of patients who underwent esophageal ESD for superficial esophageal lesions. Possible risk factors for esophageal stricture were identified by univariate and multivariate logistic regression analysis. Then we developed a prediction model according to the Framingham system for the first time and presented a convenient table containing the risk probability for each patient. In addition, we validated our score model and the previously published model in our center. RESULTS A total of 838 patients were enrolled in this study and 6 variables, including age, surgery time, location of the lesion, circumference of the lesion, longitudinal resection length, and depth of infiltration were comprised in the score model. The total score ranged from 0 to 16 points and the risk probability was presented in one concise table for each patient. Areas under receiver-operator characteristic curves for the prediction model were 0.715 in derivation group and 0.804 in validation group. CONCLUSION We designed and validated a prediction score model for esophageal stricture after ESD, which can be applied conveniently to stratify the stricture risk after esophageal ESD and may facilitate appropriate clinical decision-making for these patients.

Abstract
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.

Abstract
Esophageal stricture is a debilitating condition that negatively impacts patients' quality of life after undergoing endoscopic mucosal resection (EMR). Despite its significance, this disease remains underexplored due to the lack of a stable animal model. Under direct visualization with choledochoscopy, we retrogradely damaged the esophageal mucosal layer through the gastrostomy to create a rat model of esophageal stricture. The development of histological defects in the mucosal layer was assessed over a 2-week period after model induction. Then the models were evaluated using X-ray barium radiography, Hematoxylin-Eosin, Masson's trichrome, Sirius red, and Victoria blue staining, multiphoton microscopic imaging. Additionally, the molecular mechanisms of esophageal stricture were explored by conducting RNA transcriptome sequencing, PCR, immunohistochemistry, and immunofluorescence staining. We successfully established fifteen rat models of esophageal stricture by injuring the mucosal layer. In the model group, the mucosal defect initially occurs and subsequently repaired. The epithelium was absent and was plastically remodeled by collagen during the acute inflammatory phase (Day 1), proliferation phase (Day 7), anaphase of proliferation (Day 10), and plastic remodeling phase (Day 14). We observed increased expression of COL1A1, acta2, FGF, IL-1, and TGF-β1 pathway in the model group. We established a highly repeatable rat model of esophageal stricture, and our results suggest that the mucosal defect of the esophagus is a critical factor in esophageal stricture development, rather than damage to the muscularis layer. We identified Atp4b, cyp1a2, and gstk1 as potential targets for treating esophageal stricture, while the TGF-β pathway was found to play an important role in its development.

Abstract
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.

Abstract
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.

Abstract
BACKGROUND In recent years, with the development of endoscopic technology, endoscopic submucosal dissection (ESD) has been widely used in the treatment of early esophageal cancer (EEC) and squamous intraepithelial neoplasia (SIN) because of its low risk of complications and faster recovery. This study focused on evaluating the clinical features of EEC and SIN in elderly patients and the safety of ESD treatment.
AIM To analyze the clinical characteristics of EEC and SIN in patients of different ages.
METHODS A total of 349 patients with EEC or SIN (including high- and low-grade intraepithelial neoplasia) treated by endoscopic submucosal dissection (ESD) at the First Affiliated Hospital of Zhengzhou University from January 2019 to October 2022 were included. According to the age at the time of surgery, the patients were divided into either an elderly group (≥ 65 years old) or a young and middle-aged group (< 65 years old), and the general clinical data (gender, smoking status, alcohol consumption, hypertension, diabetes, coronary heart disease, history of other tumors, abdominal surgery history, family history of digestive tract tumor, etc.) and pathological data (lesion location, pathological type, depth of invasion, endoscopic classification, lesion length and diameter, presence of multiple lesions or not, combination with chronic esophagitis, gastric polyps, or atrophic gastritis or not, etc.) were compared between the two groups, and the postoperative related indicators (postoperative hospital stay, postoperative bleeding, esophageal stricture, and resection margin) of the two groups were compared.
RESULTS The number of patients with hypertension was significantly higher in the elderly group (P = 0.034), while the proportion of patients with smoking history was significantly higher in the middle-aged and young group (P = 0.017). In terms of lesion location, the lesions in the young and middle-aged group were mostly located in the lower thoracic segment, while the lesions in the elderly group were mostly located in the middle thoracic segment (P = 0.005); the lesions in the elderly group were more serious than those in the young and middle-aged group (P = 0.005); and the elderly group had a higher proportion of patients with combined gastric polyps (P = 0.026). In terms of complications and length of hospital stay after ESD, there was no significant difference between the two groups.
CONCLUSION Elderly patients with ESC or SIN have more comorbidities and relatively serious lesions. According to the location of the lesion, more detailed endoscopic observation and close follow-up should be carried out to improve the prognosis of such elderly patients.

Abstract
BACKGROUND Currently, endoscopic submucosal dissection (ESD) is widely used as therapeutic methods for superficial esophageal neoplasms (SENs). However, patients are likely to develop esophageal strictures after ESD. Our study aims to explore the possible risk factors for esophageal strictures after ESD and develop and validate a risk model for predicting the progression of postoperative esophageal strictures. METHODS Clinical data of patients who underwent ESD in our hospital for suspected early esophageal squamous cell carcinoma were collected from January 2014 to March 2020. The possible risk factors for postoperative esophageal strictures were analyzed by univariate and multivariate logistic regression analysis. Eventually, a risk-scoring model was built, in which 70% of patients were used to develop the model and the remaining 30% were used for validation. RESULTS A total of 553 patients who received ESD were involved, and the incidence of esophageal strictures after ESD was 16.6% (92/553). In our study, the operating time, circumferential range, lesion location, depth of infiltration, and R0 resection were independent risk factors for esophageal strictures after ESD. According to the risk of postoperative esophageal stenosis, a risk-scoring model for esophageal strictures prediction was developed. The risk score ranged from 0 to 11 points, and the risk scores were divided into low risk (0-3 points), intermediate risk (4-7 points), and high risk (8-11 points). The proportions of esophageal stenosis progression in the corresponding risk categories were 6.33%, 29.14%, and 100%. CONCLUSIONS We developed a risk-scoring model based on factors including circumferential range, lesion location, depth of infiltration, and R0 resection. It stratified patients into low-, intermediate-, and high-risk groups for postoperative esophageal strictures development. This scoring model may have the potential to guide the management of patients after ESD in the future.

Abstract
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.

Acellular Dermal Matrix Prevents Esophageal Stricture After Full Circumferential Endoscopic Submucosal Dissection in a Porcine Model. Front Bioeng Biotechnol 2022; 10:884502. [PMID: 35586551 PMCID: PMC9108161 DOI: 10.3389/fbioe.2022.884502] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2022] [Accepted: 04/14/2022] [Indexed: 11/17/2022] Open
Abstract
Esophageal stricture is a common complication after endoscopic submucosal dissection (ESD), especially in full circumferential ESD. This study investigated fully covered self-expanding metal stent (FCSEMS) placement with an acellular dermal matrix (ADM) for preventing post-ESD esophageal stricture. Twelve Bama minipigs were randomly divided into two groups, which underwent full circumferential ESD in the distal esophagus. In group A, an FCSEMS with ADM was placed at the mucosal defect, whereas group B underwent standard FCSEMS placement. The stent was removed during gastroscopy 2 weeks after the ESD procedure. At the fourth week, gastroscopy was repeated to evaluate local healing and stenosis. The animals were sacrificed, esophageal specimens were obtained for macroscopic and histological evaluation, and serum C-reactive protein (CRP) levels were quantified. Four weeks post ESD, dysphagia occurrence was lesser in group A than in group B. Group A demonstrated lesser esophageal stricture on macroscopic evaluation (21.02 ± 16.65% vs. 57.41 ± 8.48%, p = 0.001) in the form of enhanced re-epithelization (99.13 ± 0.98% vs. 96.63 ± 1.64%, p = 0.009), diminished submucosal fibrosis (1117.53 ± 188.83 um vs. 1834.69 ± 421.99 um, p = 0.003), and attenuated inflammatory infiltration (121.00 ± 30.66 vs. 188.17 ± 64.92, p = 0.045). The increase in the serum CRP level was lower in group A than in group B at 4 weeks post-ESD. FCSEMS combined with ADM can enhance re-epithelization in the process of wound healing and significantly reduce the degree of esophageal stenosis after circumferential ESD. This study provided important preclinical findings for subsequent clinical trials.

Abstract
Endoscopic submucosal dissection (ESD) is a curative treatment for superficial esophageal cancer with distinct advantages. However, esophageal stenosis after ESD remains a tough problem, especially after large circumferential proportion of esophageal mucosa is removed, which limits the wide use of ESD, especially in circumferential lesions. In this scenario, preventive procedures are highly recommended against post-ESD esophageal stenosis. However, the efficacy and safety of traditional prophylactic methods (steroids, metal and biodegradable stents, balloon dilation, radial incision, etc.) are not satisfactory and novel strategies need to be developed. Regenerative medicine has been showing enormous potential in the reconstruction of organs including the esophagus. In this review, we aimed to describe the current status of regenerative medicine in prevention of post-ESD esophageal stenosis. Cell injection, cell sheet transplantation, and extracellular matrix implantation have been proved effective. However, numerous obstacles still exist and further studies are necessary.

Long-term outcomes of refractory esophageal strictures after endoscopic submucosal dissection of superficial esophageal neoplasms. BMC Gastroenterol 2022; 22:147.

Abstract
Background Many studies have focused on prophylactic therapy for post-endoscopic submucosal dissection (ESD) of esophageal strictures. However, various strategies cannot prevent the occurrence of postoperative strictures after extensive ESD. Postoperative strictures often inevitably occur, and endoscopic dilation is still a temporarily effective therapy. Methods This study included patients with post-ESD refractory esophageal strictures (RESs) from January 2014 to November 2019. Clinical effectiveness was assessed using univariate analysis and multivariate logistic regression. Hierarchical linear models were used to identify factors that predicted the dysphagia-free period. Results A total of 50 patients fulfilled the inclusion criteria and entered the study. Twenty-seven (54%) patients had a history of prophylactic oral steroid therapy. Forty-six patients (92%) underwent ≥ 75% circumferential resection, including 32 (64%) cases involving entire circumferential ESD. The mean dysphagia-free period of 50 patients was 2.9 months (95% CI 2.3–3.5). The dysphagia-free period had a linear growth trend over time, increasing by 6.9 days per endoscopic therapy, and the estimated last dysphagia-free period was 85.9 days. Old and female patients had shorter dysphagia-free periods compared with young and male patients. Endoscopic therapy success was achieved in 30 (60%) patients. Multivariate analysis revealed that circumferential lesions (OR 6.106, 95% CI 1.013–36.785, P = 0.048) were significant predictive factors for poor clinical outcome. Conclusion Endoscopic dilation seemed effective in patients with post-ESD RESs by increasing the dysphagia-free period. After approximately 10 continuous dilations, 60% of patients achieved endoscopic success, and the remission rate of obstruction was increased. Prophylactic oral steroid therapy could reduce the occurrence of RESs. However, once a RES had occurred, prophylactic steroid therapy could not reduce the frequency of dilations or change the long-term outcomes. Trial registration: This study was prospectively registered and approved by the Ethics Committee of West China Hospital of Sichuan University (IRB number: ChiCTR-ONN-17012382) on 2015.

Abstract
Esophageal fibrosis and stricture after endoscopic submucosal dissection (ESD) are serious postoperative complications. Previous evidence has highlighted an anticancer role of β-elemene in esophageal squamous cell carcinoma. This study put forward a hypothesis on the inhibitory effect of β-elemene on esophageal fibrosis after ESD and aimed to elaborate the underlying mechanisms. Our initial network pharmacology analyses determined hypoxia-inducible factor-1alpha (HIF-1α), hexokinase 2 (HK2), and p38MAPK in association with the effect of β-elemene. We validated that the levels of HIF-1α, HK2, and p-p38MAPK were elevated in esophageal granulation tissue after ESD and corresponding fibroblasts. Esophageal fibroblasts were treated with β-elemene of gradient concentrations. The results indicated that β-elemene repressed the proliferation of esophageal fibroblasts and the levels of fibrosis-related factors. Further, β-elemene inhibited HIF-1α expression leading to restricted proliferation and augmented apoptosis of fibroblasts. HIF-1α induced p38MAPK phosphorylation by activating the HK2 transcription and consequently accelerated fibroblast proliferation. Together, β-elemene diminished HIF-1α expression and impaired the HK2-mediated p38MAPK phosphorylation, thereby repressing the esophageal fibrosis.
