Abstract
Plummer-Vinson syndrome (PVS) or Paterson-Brown-Kelly syndrome is a rare clinical condition characterized by the triad of esophageal webs/stenoses, iron-deficiency anemia, and progressively worsening dysphagia. It occurs mostly in Caucasian women in the fourth to seventh decades, particularly in northern countries. Esophageal webs and stenoses can be encountered during endoscopic evaluation for the patient's complaint of dysphagia. Esophageal stenoses are characterized as simple or complex. A stenosis should be considered refractory once the patient has undergone several sequential dilatations within short intervals, optimized treatment for potential underlying causes (eosinophilic esophagitis or acid reflux), and after neuromuscular causes have been excluded. Glucocorticoid injection into a stenosis during an endoscopic dilation session has been proven to be beneficial as the initial treatment modality of refractory nonmalignant esophageal stenoses. We present a case of a 39-year-old woman with refractory esophageal stenosis in the setting of PVS which was successfully treated with serial endoscopic glucocorticoid injections while she received oral iron supplementation. To our knowledge, there are no previous cases of esophageal stenoses associated with PVS in the literature requiring endoscopic glucocorticoid injection for successful resolution.

Zhou X, Chen H, Chen M, Ding C, Zhang G, Si X. Comparison of endoscopic injection of botulinum toxin and steroids immediately after endoscopic submucosal dissection to prevent esophageal stricture: a prospective cohort study. J Cancer 2021; 12:5789-5796. [PMID: 34475992 PMCID: PMC8408129 DOI: 10.7150/jca.60720] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2021] [Accepted: 07/06/2021] [Indexed: 11/24/2022] Open
Abstract
Background: Widespread endoscopic submucosal dissection (ESD) in early esophageal cancer patients is closely associated with esophageal stricture, which dramatically reduces patients' quality of life and increases huge medical burdens. Endoscopic injection of steroid was proved as a protective method for post-ESD strictures. Other materials such as botulinum toxin type A (BTX-A) may be potential candidates. We conducted this prospective cohort study to compare the efficacy and feasibility of endoscopic injection of BTX-A and triamcinolone acetonide (TA) for the prevention of esophageal stricture. Methods: Seventy-eight patients with esophageal mucosal defects of more than two thirds of the circumference were successively enrolled and divided into 3 groups: BTX-A group (group A, n=26), TA group (group B, n=16) and control group (group C, n=36). Patients in group A were immediately injected with BTX-A after ESD, in group B were immediately injected with TA and in group C received ESD only. Endoscopy was performed when patients reported dysphagia symptoms and at 6 and 12 weeks post-ESD in patients without symptoms. Patients who experienced post-ESD esophageal strictures in all groups received bougie dilation. All patients were followed up for one year. Results: The proportion of patients developing stricture in BTX-A group was 30.00% (intention to treat analysis, 9/30) and 26.92% (per protocol analysis, 7/26), in TA group was 40.90% (intention to treat analysis, 9/22) and 43.75% (per protocol analysis, 7/16), and in control group was 84.21% (intention to treat analysis, 32/38) and 83.33% (per protocol analysis, 30/36) (p<0.001). When further comparing between each of the two groups, the incidence of esophageal stricture was lower in BTX-A group than that in control group (p<0.001), and lower in TA group than that in control group (p=0.004). Furthermore, in entire circumference mucosal defect subgroup, the esophageal stricture was significantly lower in BTX-A group than that in TA group (33.3% vs 100%, p=0.0454). Conclusions: Endoscopic injection of BTX-A and TA were effective in preventing post-ESD esophageal strictures and BTX-A injection was particularly effective in entire circumference mucosal defect patients. Multi-centered, randomized prospective study with larger sample size should be conducted.

Can high-frequency mini-probe endoscopic ultrasonography predict outcome of endoscopic dilation in patients with benign esophageal strictures? Endosc Int Open 2020; 8:E1371-E1378. [PMID: 33015340 PMCID: PMC7508664 DOI: 10.1055/a-1223-1377] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/26/2020] [Accepted: 06/08/2020] [Indexed: 11/22/2022] Open
Abstract
Background and study aims Endoscopic dilation is first-line management for benign esophageal strictures (ES). Depth of involvement of the esophageal wall on endosonography using high frequency mini-probe (EUS-M) may predict response to dilation. This study evaluated EUS-M characteristics to predict response of ES to endoscopic dilation. Patients and methods EUS-M was used to measure the total esophageal wall thickness (EWT), involved EWT, percentage of involved wall and layers of wall involved in consecutive patients of benign ES. After a maximum of five sessions of endoscopic dilation, the cohort was divided into responders and refractory strictures. EUS-M characteristics were compared for underlying etiology as also between responders and refractory strictures. Results Of the 30 strictures (17 females, age: 47.16 ± 15.86 yrs.) 13 were anastomotic, eight corrosive, seven peptic and 2 others. Corrosive strictures had the highest involved EWT and percentage of involved wall (3.51 ± 1.36 mm; 76.38 %) followed by anastomotic (2.73 ± 1.7 mm; 65.54 %) and peptic (1.39 ± 0.62 mm; 40.71 %) ( P = 0.026 and 0.021 respectively). After five dilations, 22 were classified as responders and eight as refractory. Wall involvement > 70 % had a greater proportion of refractory strictures ( P = 0.019). Strictures with involved EWT of ≥ 2.85 mm required more dilations ( P = 0.011). Fewer dilations were required for stricture resolution with only mucosal involvement compared to deeper involvement such as submucosa and muscularis propria (2.14 vs. 5.80; P = 0.001). Conclusion EUS-M evaluation shows that corrosive and anastomotic strictures have greater depth of involvement compared to peptic strictures. Depth of esophageal wall involvement in a stricture predicts response to dilation.

Abstract
Background Delta-shaped anastomosis is a common method of intracorporeal gastroduodenostomy in totally laparoscopic distal gastrectomy. One common postoperative complication of this procedure is anastomotic stenosis, and endoscopic balloon dilatation is a major remedy for such complications. Other treatment strategies are necessary to manage unsuccessful endoscopic balloon dilatation. Case presentation We present a case where systemic steroid treatment was applied in sustained anastomotic stenosis after endoscopic balloon dilatation. We performed delta-shaped anastomosis in laparoscopic distal gastrectomy to treat early-stage gastric cancer in a patient. The patient experienced abdominal pain post-surgery; subsequent investigation revealed edematous anastomotic stenosis. The stenosis sustained even after endoscopic balloon dilatation and local steroid injection. Consequently, we applied systemic steroid treatment. Conclusion Systemic steroid treatment improved the stenosis and no recurrence was observed. These results suggest that systemic steroid application could be useful to treat anastomotic stenosis.

Abstract
OBJECTIVES Esophageal stricture is a significant complication of grade 2b and 3a esophageal injuries and causes much patient suffering. Preventing strictures would be beneficial to patients but there are currently no proven effective drugs. This study aimed to evaluate the effect of omeprazole for preventing esophageal stricture in adults with grade 2b and 3a corrosive esophageal injuries. METHODS This study was an open single-center prospective randomized controlled trial that took place from April 2018 to January 2020. Patients were randomized to standard treatment or 80 mg/day intravenously × 3 days followed by 40 mg/day orally for 4 weeks. They were endoscoped at baseline and 4 weeks post discharge. Strictures were confirmed radiologically. RESULTS 20 patients were enrolled: 15 with grade 2b and five with grade 3a injuries. Standard care and omeprazole groups numbered 10 each. At 1 month, seven and two patients developed strictures in the standard and omeprazole groups, respectively, p = 0.024, for a risk reduction of 71.4%. CONCLUSIONS Omeprazole reduced the risk of short-term developing esophageal strictures following grade 2b and 3a corrosive esophageal injuries. Larger studies are needed to reconfirm this finding.

Abstract
INTRODUCTION Anastomotic stricture formation is the most common postoperative complication after oesophageal atresia (OA) repair. The standard of care is endoscopic dilatation. A possible adjuvant treatment is intralesional steroid injection, which is thought to inhibit scar tissue formation and thereby to prevent stricture recurrence. We hypothesise that this intervention could prevent refractory strictures and reduce the total number of dilatations needed in these children. METHODS AND ANALYSIS This is an international multicentre randomised controlled trial. Children with OA type C (n=110) will be randomised into intralesional steroid injection followed by balloon dilatation or dilatation only. Randomisation and intervention will take place when a third dilatation is performed. The indication for dilatation will be confirmed with an oesophagram. One radiologist-blinded for randomisation-will review all oesophagrams. The primary outcome parameter is the total number of dilatations needed with <28 days' interval, which will be analysed with a linear-by-linear χ2 association test. Secondary outcome parameters include the level of dysphagia, the luminal oesophageal diameter and stricture length (measured on the oesophagrams), the influence of comedication on stricture formation, systemic effects of intralesional steroids (cortisol levels, length and weight) and the cost-effectiveness. Patients will undergo a second oesophagram; length and weight will be measured repeatedly; a scalp hair sample will be collected; and three questionnaires will be administered. The follow-up period will be 6 months, with evaluation at 2-3 weeks, 3 and 6 months after the intervention. ETHICS AND DISSEMINATION Patients will be included after written parental informed consent. The risks and burden associated with this trial are minimal. The institutional review board of the Erasmus Medical Centre approved this protocol (MEC-2018-1586/NL65364.078.18). The results of the trial will be published in a peer-reviewed scientific journal and will be presented at international conferences. TRIAL REGISTRATION NUMBERS 2018-002863-24 and NTR7726/NL7484.

Abstract
Caustic esophageal strictures are complex strictures with high rates of recurrence and complications. Management of these strictures requires a multipronged approach including endoscopic dilation and complex surgeries. Even with these modalities, treatment of each patient has to be individualized because it requires high clinical discretion. We present a 38-year-old female woman who had required esophagostomy and total gastrectomy in the acute phase after caustic ingestion. The definitive surgical procedure was deferred because of cicatrization of the proximal esophageal remnant. We remodeled scarred esophagus using a novel technique, which facilitated definitive surgery.

Abstract
Abstract
Background: Benign esophageal strictures are complications resulting from various causes. They can be structurally categorized in two groups: simple and complex. Treatment is similar in most cases that require dilatation and means use of three general types of dilators that are currently in use. However, despite the last guidelines on esophageal dilatation, the therapeutic response, optimal timing of treatment and interval between sessions may vary and there is no strong consensus in the literature regarding this fact.
Aims: To analyzethe first 4 year experience of Digestive Endoscopy Unit at the University Clinic of Gastroenterohepatology of the Medical Faculty, Skopje, Republic of Macedonia in treating benign esophageal strictures, since the Savary-Gilliard technique of “bougienage” was introduced for the first time in Republic of Macedonia, at our Institution, in December 2013, by assessing etiology, length of stricture, number of dilations required to achieve satisfactory therapeutic response, as well as the relationship between the type, extent of stenosis and therapeutic response.
Methods: One hundred and forty five dilations, during a period from 20th December 2013, until March 2017, have been analyzed in 31 patients
Results: The caustic strictures were the most prevalent, occurring in 15 (48%) of patients, followed by peptic stenosis presenting 26% of patients. The long and corrosive strictures needed more sessions to the absence of dysphagia. Peptic and short stenoses best respondedon treatment and needed fewer dilatation sessions per patient.
Conclusion: Caustic stricture is the most common type of benign esophageal stenosis and the most refractory to treatment, especially the long one. Peptic stenosis is the second cause of benign esophageal strictures and responded well to endoscopic therapy. The higher the extent of stenosis, the greater the number of sessions required. Short strictures have good prognoses in most cases. The number of dilations depended directly on the cause and extent of stenosis. Bouginage using Savary-Gilliard or American type of technique, irrespective of the type and the extent of esophageal stenosis, is safe and purposeful procedure.

Abstract
BACKGROUND AND PURPOSES Endoscopic resection has been worldwide recognized as a treatment strategy for early esophageal lesions. The occurrence of esophageal stricture after endoscopic resection will reduce the quality of life of patients. This study will evaluate the efficacy and safety of steroids in the prevention of esophageal stricture after endoscopic resection and the influence of different steroid administration methods. METHODS In the relevant literature database, literature from 2008 to 2018 is retrieved by using preset keywords, the search results are carefully screened, and the conclusion of the literature is synthesized to form arguments and draw conclusions. RESULTS 73 articles met our requirements. Oral steroid administration, not prophylactic endoscopic balloon dilation alone, was effective in preventing esophagostenosis after esophagoscopic treatment and reducing the number of repeated endoscopic balloon dilations even after extensive endoscopic resection. Local steroid injection is useful and economy for preventing esophageal stricture, even though it may raise the risk of perforation during dilations. A wider range of circumferential mucosal defects is an independent predictor for stricture formation for patents given preventive steroid injections after endoscopic submucosal dissection. For complete circular mucosal defect, the further researches are essential to investigate the role of local steroid injection. The effect of other methods such as steroid gel, intravenous infusion of steroid, and novel steroid filling methods require more confirmation. CONCLUSIONS Therefore, steroids play an irreplaceable role in preventing esophageal stricture after endoscopic resection. Oral and local injections of steroids are the two most acceptable methods and more prospective studies are needed to compare the effectiveness and safety of these two methods.

Abstract
BACKGROUND AND AIMS This retrospective study was aimed at assessing the efficacy of endoscopic dilation for esophageal anastomotic strictures, and to compare response between caustic anastomotic strictures (CAS) and non-caustic anastomotic strictures (NCAS). MATERIALS AND METHODS Patients with anastomotic strictures (enrolled during January 1996-December 2015) were analyzed. Short- and long-term outcomes of dilation, in terms of clinical success, refractory, and recurrent strictures were compared between NCAS and CAS. Patients with refractory and recurrent strictures were managed with adjunctive therapy including intralesional steroids. Factors predicting refractoriness at start of dilation and reasons for more than ten lifetime dilations were also evaluated. RESULTS Of the 142 patients, 124 (mean age-44.02; males-74) underwent dilation. Clinical success was achieved in 113 (91.3%) patients requiring a median [Interquartile range (IQR)] of 4 (2-10) sessions. The number of dilations to achieve clinical success, refractory strictures, and recurrent strictures, and the use of adjunctive therapy were significantly higher for CAS than for NCAS. Intralesional steroid use decreased periodic dilation index (PDI) significantly in CAS. Caustic etiology and starting dilation diameter of < 10 mm were found to be predictors of refractoriness, with the former alone being an independent predictor of more than ten lifetime dilations. No patient had free perforation; however, five required revision surgery. CONCLUSION Patients with CAS fared worse than those with NCAS in terms of number of dilations, refractoriness, recurrence of strictures, and need of adjunctive therapy. Endoscopic dilation can successfully ameliorate dysphagia due to anastomotic strictures in a majority of patients.

Abstract
Introduction Circumferential endoscopic submucosal dissection (ESD) allows to treat large esophageal superficial neoplasms, however with a high occurrence of severe esophageal strictures. In a previous work, we demonstrated that the application of a prototype of self-assembling peptide (SAP) matrix on esophageal wounds after a circumferential-ESD delayed the onset of esophageal stricture in a porcine model. The aim of this work was to consolidate these results using the commercialized version of this SAP matrix currently used as a hemostatic agent. Animals and methods Eleven pigs underwent a 5 cm-long circumferential esophageal ESD under general anesthesia. Five pigs were used as a control group and six were treated with the SAP. In the experimental group, 3.5 mL of the SAP matrix were immediately applied on the ESD wound. Stricture rates and esophageal diameter were assessed at day 14 by endoscopy and esophagram, followed by necropsy and histological measurements of inflammation and fibrosis in the esophageal wall. Results At day 14, two animals in the treated group had an esophageal stricture without any symptom, while all animals in the control group had regurgitations and an esophageal stricture (33 vs. 100%, p = 0.045). In the treated group, the mean esophageal diameter at day 14 was 9.5 ± 1 mm vs. 4 ± 0.6 mm in the control group (p = 0.004). Histologically, the neoepithelium was longer in the SAP treated group vs. the control (3075 μm vs. 1155μm, p = 0.014). On immunohistochemistry, the expression of alpha smooth muscle actin was lower in the treated vs. control group. Conclusion Apposition of a self-assembling peptide matrix immediately after a circumferential esophageal ESD reduced by 67% the occurrence of a stricture at day 14, by promoting reepithelialization of the resected area.

Abstract
BACKGROUND Restenosis occurs in 10% to 30% of patients after endoscopic balloon dilation (EBD) of benign esophageal stricture. This study aimed to investigate whether an orally administered steroid/gel mixture would inhibit restenosis after EBD for benign esophageal stricture. METHODS This retrospective analysis included patients with benign esophageal stricture treated with EBD at the Peking University Third Hospital, China (September 2005 to October 2017). The patients were divided into an EBD alone group (EBD only) and EBD/OHA group (EBD plus oral hydrocortisone sodium succinate/aluminum phosphate gel mixture). Patients were followed-up for 3 months. EBD was repeated for persistent dysphagia. The outcome measures included the restenosis rate and the number of additional EBD sessions required during follow-up. Any side effects were noted. RESULTS Thirty-two patients were included (EBD alone group, n = 12; EBD/OHA group, n = 20). Baseline demographic and clinical characteristics (including age, sex, etiology, stricture location, and diameter of narrowest segment) did not differ between groups. Restenosis rate was significantly lower in the EBD/OHA group than in the EBD alone group (5/20, 25.0% vs 8/12, 66.7%; P = .025). The median number of EBD sessions required was numerically lower in the EBD/OHA group (median, 1.0; interquartile range, 1.0-1.8) than in the EBD alone group (median 2.0, interquartile ranged 1.0-2.5), but statistical significance was not attained (P = .071). The only side effects occurred in the EBD/OHA group: hypokalemia in 4/20 (20.0%) and apathy/somnolence in 1/20 (5.0%). CONCLUSIONS An orally administered steroid/gel mixture might reduce the incidence of restenosis after EBD for benign esophageal stricture, but it requires confirmation by prospective trials.

Abstract
Peptic oesophageal stricture can be considered as the end result of prolonged gastro-oesophageal reflux. The 'gold standard' treatment for peptic stricture is endoscopic dilatation with balloon or bougie. It is predicted that up to 40% of patients remain symptomatic with dysphagia due to refractory (resistant to treatment) or recurrent strictures, needing frequent interventions at short intervals. Such patients have poor nutritional status due to the primary disease and are susceptible to complications related to repeated endoscopic dilatation such as bleeding and perforation. This general review aims to analyse existing published evidence and address the role of biodegradable stents in resistant peptic strictures as an alternative treatment to provide long-term dysphagia-free intervals.

Endoscopic balloon dilatation is an effective management strategy for caustic-induced gastric outlet obstruction: a 15-year single center experience. Endosc Int Open 2019; 7:E53-E61. [PMID: 30648140 PMCID: PMC6327726 DOI: 10.1055/a-0655-2057] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/16/2018] [Accepted: 05/30/2018] [Indexed: 01/10/2023] Open
Abstract
Background and study aims There is sparse data on the endoscopic management of caustic-induced gastric outlet obstruction (GOO). The present retrospective study aimed to define the response to endoscopic balloon dilatation (EBD) in such patients and their long-term outcome. Patients and methods The data from symptomatic patients of caustic-induced GOO who underwent EBD at our tertiary care center between January 1999 and June 2014 were retrieved. EBD was performed using wire-guided balloons in an incremental manner. Procedural success and clinical success of EBD were evaluated, including complications and long-term outcome. Results A total of 138 patients were evaluated of whom 111 underwent EBD (mean age: 30.79 ± 11.95 years; 65 male patients; 78 patients with isolated gastric stricture; 33 patients with both esophagus plus gastric stricture). The initial balloon diameter at the start of dilatation, and the last balloon diameter were 9.6 ± 2.06 mm (6 - 15 mm) and 14.5 ± 1.6 mm (6 - 15 mm), respectively. Procedural and clinical success was achieved in 95 (85.6 %) and 108 (97.3 %) patients, respectively, requiring a mean (SD) of 5.3 (2.6) and 7.21 (3.86) sessions, respectively. Patients with isolated gastric obstruction had a better response than those with combined esophagus and gastric stricture. Minor complications such as self-limited pain or bleeding were seen in 18 (16.2 %) and 16 (14.4 %), respectively. Perforation occurred in two patients. Over a follow-up period of 98 months, there were no recurrences. Conclusion Caustic-induced GOO can be successfully managed using EBD with 97.3 % clinical success.

Exp Ther Med 2018; 16:5248-5252. [PMID: 30542481 PMCID: PMC6257434 DOI: 10.3892/etm.2018.6858] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2018] [Accepted: 10/05/2018] [Indexed: 12/14/2022] Open
Abstract
Effect and prognosis of endoscopic balloon dilatation combined with submucosal triamcinolone acetonide on treating benign esophageal lesions were explored. This retrospective study included patients with esophageal stricture treated in the Department of Gastroenterology, the Third Affiliated Hospital of Soochow University from March 2012 to March 2015. Enrolled patients were divided into the treatment and control group depending on the therapy differences. Endoscopic balloon dilation combined with submucosal injection of triamcinolone acetonide was performed in the treatment group and the endoscopic balloon dilatation was performed in the control group. In addition, the treatment group was further divided into the <16- and >16-mm subgroup according to the degree of balloon dilatation. During 1-year follow-up, changes of esophageal stenosis, esophageal stenosis recurrence rate, postoperative complications and adverse reactions were observed and analyzed. The improvement of esophageal stenosis of the treatment group was significantly superior to that of the control group at 2 and 4 months after operation, respectively (P=0.002, 0.013). The esophageal stenosis recurrence rate was 62.2 and 77.2% in the treatment and control group, respectively (P=0.027); the recurrence time of stenosis was 101.4±8.6 days in the treatment group and 75.4±5.2 days in the control group (P=0.006). Additionally, the recurrence time of esophageal stenosis was significantly shorter in the >16-mm subgroup compared with that of the <16-mm subgroup (P<0.001). Endoscopic balloon dilatation combined with local injection of triamcinolone acetonide in the treatment of esophageal stricture had a better therapeutic effect than that of the simple balloon dilatation, which was more effective when the balloon dilatation was >16 mm. It could significantly prolong the recurrence time of esophageal stricture.

Abstract
Objectives To evaluate the efficacy and safety of endoscopic intralesional triamcinolone injection (ITI) for benign esophageal strictures combined with endoscopic dilation (ED). Methods Online databases including MEDLINE, EMBASE, the Cochrane Library, and Web of Science were comprehensively searched for prospective randomized control trials (RCTs) between 1966 and March 2018. A meta-analysis was conducted according to the methods recommended by the Cochrane Collaboration. Results Six RCTs consisting of 176 patients were selected. Meta-analysis results showed that additional ITI had a significant advantage in terms of stricture rate and required ED sessions. Surgery-related and non-surgery-related strictures showed similar results. Additional ITI was not associated with significantly increased risk of complications. Conclusions Our meta-analysis showed that additional ITI therapy was supposed to be effective and safe for benign esophageal strictures as it reduced the stricture rate and required ED sessions. However, more RCTs are necessary to support these findings.

Abstract
AIM To analyze the effect of intralesional steroid injections in addition to endoscopic dilation of benign refractory esophageal strictures. METHODS A comprehensive search was performed in three databases from inception to 10 April 2017 to identify trials, comparing the efficacy of endoscopic dilation to dilation combined with intralesional steroid injections. Following the data extraction, meta-analytical calculations were performed on measures of outcome by the random-effects method of DerSimonian and Laird. Heterogeneity of the studies was tested by Cochrane's Q and I2 statistics. Risk of quality and bias was assessed by the Newcastle Ottawa Scale and JADAD assessment tools. RESULTS Eleven articles were identified suitable for analyses, involving 343 patients, 235 cases and 229 controls in total. Four studies used crossover design with 121 subjects enrolled. The periodic dilation index (PDI) was comparable in 4 studies, where the pooled result showed a significant improvement of PDI in the steroid group (MD: -1.12 dilation/month, 95%CI: -1.99 to -0.25 P = 0.012; I2 = 74.4%). The total number of repeat dilations (TNRD) was comparable in 5 studies and showed a non-significant decrease (MD: -1.17, 95%CI: -0.24-0.05, P = 0.057; I2 = 0), while the dysphagia score (DS) was comparable in 5 studies and did not improve (SMD: 0.35, 95%CI: -0.38, 1.08, P = 0.351; I2 = 83.98%) after intralesional steroid injection. CONCLUSION Intralesional steroid injection increases the time between endoscopic dilations of benign refractory esophageal strictures. However, its potential role needs further research.

Abstract
Endoscopic submucosal dissection (ESD) has been widely accepted as an effective, minimally invasive treatment for superficial esophageal cancers. However, esophageal stricture often occurs in patients with large mucosal defects after ESD. In this review, we discuss various approaches recently researched to prevent esophageal strictures after ESD. These approaches can be classified as pharmacological treatments, esophageal stent treatments, and tissue engineering approaches. Most of the preventive approaches still have their limitations and require further research. With the improvement of current therapies, ESD can be more widely utilized as a minimally invasive treatment with minimal complications.

Abstract
BACKGROUND Our objective was to investigate the efficacy and safety of oral prednisone for the prevention of esophageal stricture formation after endoscopic submucosal dissection (ESD) in an optimal administration program. METHODS Patients who underwent circumferential or semi-circumferential (more than three quarters but not a complete circular) ESD for esophageal squamous cell carcinoma were eligible for this study. Oral prednisolone was administered to the study group at a dose of 30 mg/day on the third day post-ESD, and then tapered gradually (30, 25, 20, 15, 10, and 5 mg for 14 days). Serial esophagoscopy with iodine staining was performed to assess stenosis and tumor recurrence at one, three, six, and 12 months after ESD. Endoscopic balloon dilatation was performed whenever patients experienced persistent dysphagia to solids. Data were statistically analyzed. RESULTS Twenty-three patients (15 men, mean age 66.6 years) were enrolled in the study. Post-procedural esophageal stricture was significantly lower in the study group (23.1%) compared to the control (80%) (P < 0.05). A significantly higher number of endoscopic balloon dilatation sessions were performed (P < 0.05) in the control (13.5) than in the study group (0.69). There were no adverse events related to oral prednisolone or the procedure itself and no treatment-related mortality was observed during the 12 month follow-up. CONCLUSIONS Our study suggested an optimal administration program of oral prednisone therapy and demonstrated that it is safe and effective for the prevention of esophageal stricture in patients after complete or semi-circular ESD for esophageal squamous cell carcinoma.

Abstract
Biodegradable (BD) stents have been used for the management of various esophageal strictures (ES) but the experience of its use in caustic strictures is limited. The present study, aimed at evaluating efficacy of BD stents for the treatment of refractory caustic-induced ES, was a retrospective multi-center study conducted at three tertiary care centers in India wherein adult patients with refractory caustic induced strictures underwent placement of a BD stent. Patients were followed up for immediate complications and long term outcome. All 13 patients (39.3 ± 15.1 years) underwent successful BD stent placement. Retrosternal chest pain occurred in 2 patients and stent migration in 1 (7.6%) patient. At 3 months, restenosis with recurrence of dysphagia was seen in nine (69.2%) patients, at 6 months, 10 (77%) patients had dysphagia of whom three underwent surgery and the remaining seven patients required dilatations. At 1 year, one patient remained asymptomatic while nine had dysphagia. The requirement for dilatation was once in 3 months in seven patients & once in a month in two patients. At 2 years, the requirement of dilatations was further reduced to once in 4-6 months in all patients. Over a 3 year follow up three (23%) patients had undergone surgery, one was free of symptoms while nine patients continued to be on periodic dilatation although the requirement had reduced to once in 4-6 months. Efficacy of BD stents in patients with caustic-induced ES is limited and the short term radial force applied by the currently available BD stents is inadequate to provide long term relief in such patients.

Abstract
Background In type 1 multiple endocrine neoplasia (MEN1), esophageal diseases association with excessive gastrin secretion in Zollinger-Ellison syndrome (ZES) sometimes develop. Here, we reported a case of MEN1/ZES, who developed dysphagia due to reflux esophagitis with severe esophageal stricture. Treatment for his esophageal stricture and ZES was discussed. Case presentation A 43-year-old man with progressive dysphagia and diarrhea was referred to the teaching hospital. He had a history of recurrent duodenojejunal perforations despite the anti-secretory medication. Blood examinations revealed elevated serum gastrin, calcium, and parathyroid hormone. Upper gastrointestinal endoscopy demonstrated a severe esophageal stricture, multiple gastroduodenal ulcer scars, and a duodenal submucosal tumor. Enhanced computed tomography showed multiple hypervascular tumors within the pancreas and duodenum, suggestive of MEN1. Genetic examination demonstrated a pathogenic MEN1 mutation. Repetitive endoscopic esophageal dilatation with intralesional corticosteroid injection, coupled with pancreatoduodenectomy were performed to improve the patient’s symptoms and to treat pancreatic tumors. The histology of multiple tumors in the duodenum and pancreas were all consistent with neuroendocrine tumors. His hypergastrinemia subsided and he remained asymptomatic in his gastrointestinal tract after these treatments. Conclusion For esophageal stenosis in case of MEN1/ZES, anti-secretory therapy and endoscopic dilatation with corticosteroid injection could be recommended. However, in refractory cases with repetitive and/or severe complications due to high acid secretion, surgical treatment could be considered as an option.

Single Locoregional Triamcinolone Injection Immediately After Esophageal Endoscopic Submucosal Dissection Prevents Stricture Formation. Clin Transl Gastroenterol 2017; 8:e75. [PMID: 28230852 PMCID: PMC5387750 DOI: 10.1038/ctg.2017.5] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/19/2016] [Accepted: 01/09/2017] [Indexed: 12/22/2022] Open
Abstract
OBJECTIVES Although endoscopic submucosal dissection (ESD) is an efficient treatment for superficial esophageal cancer, it is associated with stricture formation after wide-circumference resection that leads to a low quality of life. Although locoregional steroid injections prevent stricture formation, a randomized comparative study did not report any advantages associated with steroid injection. We evaluated the prophylactic efficacy of a single locoregional triamcinolone injection for stricture formation after esophageal ESD. METHODS This was a retrospective matched case-control study using propensity score matching (PSM). Between April 2006 and July 2015, a total of 602 patients with superficial esophageal neoplasia underwent ESD. Among them, 189 patients with mucosal defects that spanned more than 2/3 of the esophageal circumference were included. After exclusion, 150 patients were enrolled. Triamcinolone acetonide (80 mg) was injected into the residual submucosal layer of the resected region immediately after ESD. PSM was performed to reduce the effects of selection bias for steroid injection. The primary outcome was the incidence of stricture formation. The secondary outcome was the number of balloon dilatation procedures required to resolve the stricture formation. RESULTS Thirty-seven patients, with and without triamcinolone injection each, were matched after PSM. The incidence of stricture formation decreased from 45.9% (17/37) without triamcinolone injection to 18.9% (7/37) with triamcinolone injection (p=0.016). After matching, the mean number of balloon dilatation procedures required also decreased from 2.8±4.6 to 0.6±1.5 times (P<0.01). CONCLUSIONS A single locoregional triamcinolone injection efficiently prevented stricture formation after esophageal ESD.

An Intractable Caustic Esophageal Stricture Successfully Managed with Sequential Treatment Comprising Incision with an Insulated-Tip Knife, Balloon Dilation, and an Oral Steroid. Clin Endosc 2016; 49:560-563. [PMID: 27515392 PMCID: PMC5152773 DOI: 10.5946/ce.2016.048] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/14/2016] [Revised: 07/19/2016] [Accepted: 07/22/2016] [Indexed: 12/22/2022] Open
Abstract
Bougie or balloon dilation is a good short-term treatment for caustic esophageal strictures, although recurrence after dilation occurs in approximately 30% of these cases. Therefore, long-term treatment options are required in some cases, and endoscopic incisional therapy has been used for patients with an anastomotic stricture in the gastrointestinal tract. A 58-year-old woman presented with severe swallowing difficulty because of a caustic esophageal stricture, which was caused by accidental exposure to anhydrous acetic acid at infancy. She had undergone several previous bougie and balloon dilations but the stricture did not improve. We performed sequential treatment comprising incision with an insulated-tip knife, balloon dilation, and an oral steroid, which resulted in the patient’s symptoms markedly improving. Thus, we report this case of an intractable caustic esophageal stricture, which was successfully treated using combined endoscopic sequential treatment.

Abstract
BACKGROUND The lower rectum close to the dentate line has distinct characteristics, making endoscopic submucosal dissection (ESD) of tumors challenging. We assessed clinical outcomes of ESD for such patients with hemorrhoids. METHODS Sixty-four patients (mean age, 68 years) underwent ESD for anorectal tumors close to the dentate line. We divided patients into those with (Group A, 45 patients) and without hemorrhoids (Group B, 19 patients). We examined en bloc and histological en bloc resection rates, procedure time, complication rates, and postoperative prognosis after ESD. RESULTS The mean tumor size was 43 mm. Histologic diagnoses were adenoma (42 %, 27/64), carcinoma in situ (44 %, 28/64), and T1 carcinoma (14 %, 9/64). There was no significant difference in en bloc resection (93 %, 42/45 vs. 95 %, 18/19) or postoperative bleeding rates (16 %, 7/45 vs. 11 %, 2/19) between Groups A and B, respectively. The mean procedural durations were 120 and 124 min, respectively, in Groups A and B. No perforations occurred. There was no significant difference in postoperative anal pain rate between Groups A (18 %, 8/45) and B (16 %, 3/19), and it resolved within a few days in all cases. There was one case of stricture in Group B. Two patients with T1 carcinoma underwent additional surgery, one underwent chemotherapy, and five had no additional treatment. No recurrence occurred during the follow-up period of 38 months. CONCLUSIONS ESD is safe and effective for anorectal tumors close to the dentate line in patients with hemorrhoids.

Abstract
Benign esophageal strictures refractory to the conventional balloon or bougie dilatation may be subjected to various adjunctive modes of therapy, one of them being endoscopic incisional therapy (EIT). A proper delineation of the stricture anatomy is a prerequisite. A host of electrocautery and mechanical devices may be used, the most common being the use of needle knife, either standard or insulated tip. The technique entails radial incision and cutting off of the stenotic rim. Adjunctive therapies, to prevent re-stenosis, such as balloon dilatation, oral or intralesional steroids or argon plasma coagulation can be used. The common strictures where EIT has been successfully used are Schatzki’s rings (SR) and anastomotic strictures (AS). Short segment strictures (< 1 cm) have been found to have the best outcome. When compared with routine balloon dilatation, EIT has equivalent results in treatment naïve cases but better long term outcome in refractory cases. Anecdotal reports of its use in other types of strictures have been noted. Post procedure complications of EIT are mild and comparable to dilatation therapy. As of the current evidence, incisional therapy can be used for management of refractory AS and SR with relatively short stenosis (< 1 cm) with good safety profile and acceptable long term patency.

Abstract
BACKGROUND Endoscopic submucosal dissection (ESD) of extensive superficial cancers of the esophagus may progress with high rates of postoperative stenosis, resulting in significantly decreased quality of life. Several therapies are performed to prevent this, but have not yet been compared in a systematic review. METHODS A systematic review of the literature and meta-analysis were performed using the MEDLINE, Embase, Cochrane, LILACS, Scopus, and CINAHL databases. Clinical trials and observational studies were searched from March 2014 to February 2015. Search terms included: endoscopy, ESD, esophageal stenosis, and esophageal stricture. Three retrospective and four prospective (three randomized) cohort studies were selected and involved 249 patients with superficial esophageal neoplasia who underwent ESD, at least two-thirds of the circumference. We grouped trials comparing different techniques to prevent esophagus stenosis post-ESD. RESULTS We conducted different meta-analyses on randomized clinical trials (RCT), non-RCT, and global analysis. In RCT (three studies, n = 85), the preventive therapy decreased the risk of stenosis (risk difference = -0.36, 95 % CI -0.55 to -0.18, P = 0.0001). Two studies (one randomized and one non-randomized, n = 55) showed that preventative therapy lowered the average number of endoscopy dilatations (mean difference = -8.57, 95 % CI -13.88 to -3.25, P < 0.002). There were no significant differences in the three RCT studies (n = 85) in complication rates between patients with preventative therapy and those without (risk difference = 0.02, 95 % CI -0.09 to 0.14, P = 0.68). CONCLUSIONS The use of preventive therapy after extensive ESD of the esophagus reduces the risk of stenosis and the number of endoscopic dilatations for resolution of stenosis without increasing the number of complications.

Abstract
INTRODUCTION Postoperative benign anastomotic strictures (POBAS) which develop after surgical resections of the gastrointestinal system (GIS) present with symptoms depending on location of the stricture. Diagnosis is confirmed by endoscopic and radiological methods. Although bougie or balloon dilatation is preferred in management, the endoscopic incision method (EIM) is also used with considerable success. In this trial, we aimed to evaluate EIM, which is one of the endoscopic dilatation techniques used in postoperative anastomotic stricture of GIS. MATERIAL AND METHODS A total of 20 POBAS patients, 12 men and 8 women, subjected to EIM intervention for strictures, were enrolled in the trial. The number of patients with upper GIS strictures was 6 (30%), while the number of cases with lower GIS strictures was 14 (70%). RESULTS Dilatation of the stricture was achieved in 15 (75%) patients with one treatment session, while more than one session of EIM was needed in 5 (25%) cases. Mean duration of follow-up of patients was 10.65 ±5.86 (0-25) months. Procedure-related complications developed in 8 patients. Among them, 7 were minor complications and improved without any treatment. In only 1 (5%) patient, perforation was observed as a major complication. Following EIM, recurrence of POBAS was observed in 5 (25%) patients. The following parameters were found to have an impact on successful outcome in EIM: presence or absence of a tortuous lumen in POBAS (p = 0.035) and length of stricture (p = 0.02), complications during the procedure (if any), and presence of single or multiple strictures. CONCLUSIONS Endoscopic incision method may be regarded as a favorable approach among first choice treatment alternatives in uncomplicated anastomotic strictures of GIS, or it may be used as an adjunctive dilatation method.

Abstract
INTRODUCTION Lesions of the upper digestive tract due to ingestion of caustic agents still represent a major medical and surgical emergency worldwide. The work-up of these patients is poorly defined and no clear therapeutic guidelines are available. PURPOSE OF THE STUDY The aim of this study was to provide an evidence-based international consensus on primary and secondary prevention, diagnosis, staging, and treatment of this life-threatening and potentially disabling condition. METHODS An extensive literature search was performed by an international panel of experts under the auspices of the World Society of Emergency Surgery (WSES). The level of evidence of the screened publications was graded using the Oxford 2011 criteria. The level of evidence of the literature and the main topics regarding foregut caustic injuries were discussed during a dedicated meeting in Milan, Italy (April 2015), and during the 3rd Annual Congress of the World Society of Emergency Surgery in Jerusalem, Israel (July 2015). RESULTS One-hundred-forty-seven full papers which addressed the relevant clinical questions of the research were admitted to the consensus conference. There was an unanimous consensus on the fact that the current literature on foregut caustic injuries lacks homogeneous classification systems and prospective methodology. Moreover, the non-standardized definition of technical and clinical success precludes any accurate comparison of therapeutic modalities. Key recommendations and algorithms based on expert opinions, retrospective studies and literature reviews were proposed and approved during the final consensus conference. The clinical practice guidelines resulting from the consensus conference were approved by the WSES council. CONCLUSIONS The recommendations emerging from this consensus conference, although based on a low level of evidence, have important clinical implications. A world registry of foregut caustic injuries could be useful to collect a homogeneous data-base for prospective clinical studies that may help improving the current clinical practice guidelines.

Locoregional steroid injection prevents stricture formation after endoscopic submucosal dissection for esophageal cancer: a propensity score matching analysis. Surg Endosc 2015; 30:1441-9.

Abstract
BACKGROUND Although endoscopic submucosal dissection (ESD) has become accepted for the treatment of superficial esophageal cancer, the incidence of stricture formation caused by ESD for widespread lesions is high and leads to a low quality of life. A few studies reported that locoregional steroid injections are useful for the prevention of such stricture formation compared with historical controls. We evaluated the efficacy of prophylactic locoregional steroid injections for stricture formation caused by ESD using quasi-randomized analysis. METHODS This matched case-control study included 461 superficial esophageal cancers from 305 patients who underwent ESD between 2006 and 2013. We used two methods of locoregional steroid injection to prevent stricture formation after ESD. A propensity score matching analysis was performed to reduce the effects of a selection bias for steroid injections and other potential confounding factors. In addition, generalized estimating equations were used to analyze repeated measures data. We compared the incidence of stricture formation with or without steroid injections. RESULTS Forty-two lesions were treated with locoregional steroid injection (dexamethasone/triamcinolone, 23/19) after ESD and esophageal stricture formation occurred in 36 lesions. Fifty-six lesions treated with or without steroid injections were matched after propensity score matching. Locoregional steroid injection reduced the incidence of stricture formation to 10.7% (3/28) of patients compared with 35.7% (10/28) in the control group (odds ratio 4.63, 95% confidence interval 1.11-19.25, p = 0.035). CONCLUSIONS Locoregional steroid injections could be efficient for the prevention of stricture formation after ESD for superficial esophageal cancer.

Abstract
BACKGROUND AND AIMS Endoscopic submucosal dissection (ESD) was developed in Japan and has been performed on many patients with early stage esophageal cancer; however quality of life in patients with postoperative stricture is drastically decreased and repeat, periodic endoscopic balloon dilatation (EBD) is usually required over long periods. In this study, we evaluate the efficacy of short period, low dose oral prednisolone in controlling post-procedural esophageal stricture. PATIENTS AND METHODS In total, 33 patients who underwent semicircular or complete circular ESD for esophageal superficial squamous cell carcinoma were included in this study. They were divided into two groups: those who underwent large-circumference ESD with no preventative treatment for stricture (ESD alone group) and those who received systemic steroid treatment for stricture (oral prednisolone group). We compared the two groups in terms of stricture rate and total number of EBD sessions. The ESD alone group underwent no preventative treatment. The oral prednisolone group started with 30 mg/day prednisolone on the second day post-ESD, and continued with a gradually tapering prednisolone dose, finally discontinuing systemic steroid administration 3 weeks later. RESULTS The stricture rate after ESD was significantly lower in the oral prednisolone group (3 of 17 patients; 17.6 %) than in the ESD alone group (11 of 16 patients; 68.7 %) (P < 0.01). The number of EBD sessions was significantly lower in the oral prednisolone group than in the ESD alone group (median 4.6, range 2 - 10 vs. median 8.1, range 1 - 18; P < 0.01). CONCLUSION Short period, low dose oral prednisolone showed promising results for the prevention of stricture after ESD for early stage esophageal cancers.

Abstract
Benign esophageal strictures arise from a diversity of causes, for example esophagogastric reflux, esophageal resection, radiation therapy, ablative therapy, or the ingestion of a corrosive substance. Most strictures can be treated successfully with endoscopic dilation using bougies or balloons, with only a few complications. Nonetheless, approximately one third of patients develop recurrent symptoms after dilation within the first year. The majority of these patients are managed with repeat dilations, depending on their complexity. Dilation combined with intra lesional steroid injections can be considered for peptic strictures, while incisional therapy has been demonstrated to be effective for Schatzki rings and anastomotic strictures. When these therapeutic options do not resolve the stenosis, stent placement should be considered. Self bougienage can be proposed to a selected group of patients with a proximal stenosis. As a final step surgery is an option, but even then the risk of stricture formation at the anastomotic site remains. This chapter reviews refractory benign esophageal strictures and the treatment options that are currently available.

Abstract
BACKGROUND Esophageal stenosis following endoscopic submucosal dissection (ESD) is a serious adverse event that makes subsequent management more difficult. METHODS This parallel, randomized, controlled, open-label study was designed to examine whether local steroid injection is an effective prophylactic treatment for esophageal stenoses following extensive ESD. This single center trial was conducted at the Keiyukai Hospital, a tertiary care center for gastrointestinal disease in Japan [University Hospital Medical Network Clinical Trial Registry (UMIN-CTR) on 15 September 2011 (UMIN000006327)]. Thirty-two patients with mucosal defects involving ≥75% of the esophageal circumference were randomized to receive a single dose of triamcinolone acetonide injections (n = 16) or be treated conventionally (n = 16). The primary outcome was the frequency of stricture requiring endoscopic dilatation; the surrogate primary endpoint was the number of dilatation sessions needed. Secondary outcomes included adverse event rates, the minimum diameter of the stenotic area and the duration of the course of dilatation treatments. RESULTS The frequency of stricture was not significantly different between the groups because of insufficient statistical power, but the number of dilatation sessions required was significantly less in the steroid group (6.1 sessions [95% confidence interval, CI 2.8-9.4] versus 12.5 [95% CI 7.1-17.9] sessions in the control group; P = 0.04). The perforation rate was similar in both groups. The minimum diameter of stenotic lumens was significantly greater in the treatment group than controls (11.0 mm versus 7.1 mm, respectively; P = 0.01). The perforation rate was not significantly different between the groups (1.0% versus 0.5% in the treatment and control group, respectively). Steroid injection was effective in cases of mucosal defects encompassing the entire esophageal circumference. CONCLUSIONS Prophylactic endoscopic steroid injection appears to be a safe means of relieving the severity of esophageal stenoses following extensive ESD.

Stricture occurring after endoscopic submucosal dissection for esophageal and gastric tumors. Clin Endosc 2014; 47:516-22. [PMID: 25505717 PMCID: PMC4260099 DOI: 10.5946/ce.2014.47.6.516] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/04/2013] [Accepted: 07/16/2013] [Indexed: 12/15/2022] Open
Abstract
Endoscopic submucosal dissection (ESD) is a widely accepted treatment for early gastric and esophageal cancer. Compared to endoscopic mucosal resection, ESD has the advantage of enabling en bloc removal of tumors regardless of their size. However, ESD can result in a large artificial ulcer, which may lead to a considerable deformity. Circumferential mucosal defects of more than three-fourths the esophageal circumference, long longitudinal mucosal defects (>30 mm), and lesions in the upper esophagus are significant risk factors for the development of post-ESD strictures of the esophagus. In the stomach, a circumferential mucosal defects more than three-fourths in extent and longitudinal mucosal defects >5 cm are risk factors of post-ESD stricture. If scheduled early, regular endoscopic balloon dilation is effective in controlling and preventing post-ESD stricture. Moreover, intralesional steroid injections or oral steroids can achieve remission of dysphagia or reduce the need for repeated endoscopic balloon dilation. However, further study is needed to improve the prevention of stricture formation.

Abstract
Endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD) have recently been accepted as less invasive methods for treating patients with early esophageal cancers such as squamous cell carcinoma and dysplasia of Barrett’s esophagus. However, the large defects in the esophageal mucosa often cause severe esophageal strictures, which dramatically reduce the patient’s quality of life. Although preventive endoscopic balloon dilatation can reduce dysphagia and the frequency of dilatation, other approaches are necessary to prevent esophageal strictures after ESD. This review describes several strategies for preventing esophageal strictures after ESD, with a particular focus on anti-inflammatory and tissue engineering approaches. The local injection of triamcinolone acetonide and other systemic steroid therapies are frequently used to prevent esophageal strictures after ESD. Tissue engineering approaches for preventing esophageal strictures have recently been applied in basic research studies. Scaffolds with temporary stents have been applied in five cases, and this technique has been shown to be safe and is anticipated to prevent esophageal strictures. Fabricated autologous oral mucosal epithelial cell sheets to cover the defective mucosa similarly to how commercially available skin products fabricated from epidermal cells are used for skin defects or in cases of intractable ulcers. Fabricated autologous oral-mucosal-epithelial cell sheets have already been shown to be safe.

Abstract
Endoscopic submucosal dissection (ESD) for the treatment of esophageal mucosal lesions is associated with a risk of esophageal stenosis, especially for near-circumferential or circumferential esophageal mucosal defects. Here, we review historic and modern studies on the prevention and treatment of esophageal stenosis after ESD. These methods include prevention via pharmacological treatment, endoscopic autologous cell transplantation, endoscopic esophageal dilatation, and stent placement. This short review will focus on direct prevention and treatment, which may help guide the way forward.

Abstract
BACKGROUND AND AIMS Postoperative esophageal strictures frequently recur. We assessed the efficacy of injecting triamcinolone after bougie dilation in comparison to dilation alone. METHODS In a double-blind randomized fashion, 19 patients (68% male with mean age of 53-years old) with non-dilated esophagogastric complex strictures after esophagectomy with gastric pull-up were assigned to receive dilation alone (control) or 40 mg of triamcinolone at the borders of the wall lacerations caused by the bougienage in each dilation session during the study follow-up. Dysphagia and complications were assessed at 1, 2, and 6 months. Primary end-point was to be dysphagia-free. RESULTS After 1 month of the beginning of therapy, 4 patients in the steroid group were without dysphagia, in comparison to 0 patient in the control group (P = 0.021). Six months after endoscopic therapy, 62% of the cases in the triamcinolone group versus none in the control group were dysphagia-free (P = 0.009). There was no perforation nor hemorrhage. CONCLUSIONS Injecting triamcinolone after every dilation session next to or at the borders of the lacerations caused by the dilators, results in a significant improvement or resolution of dysphagia.

Abstract
BACKGROUND/AIMS Stricture formation is a common complication after endoscopic mucosal resection. Predictors of stricture formation have not been well studied. METHODS We conducted a retrospective, observational, descriptive study by using a prospective endoscopic mucosal resection database in a tertiary referral center. For each patient, we extracted the age, sex, lesion size, use of ablative therapy, and detection of esophageal strictures. The primary outcome was the presence of esophageal stricture at follow-up. Multivariate logistic regression was used to analyze the association between the primary outcome and predictors. RESULTS Of 136 patients, 27% (n=37) had esophageal strictures. Thirty-two percent (n=44) needed endoscopic dilation to relieve dysphagia (median, 2; range, 1 to 8). Multivariate logistic regression analysis showed that the size of the lesion excised is associated with increased odds of having a stricture (odds ratio, 1.6; 95% confidence interval, 1.1 to 2.3; p=0.01), when controlling for age, sex, and ablative modalities. Similarly, the number of lesions removed in the index procedure was associated with increased odds of developing a stricture (odds ratio, 2.3; 95% confidence interval, 1.3 to 4.2; p=0.007). CONCLUSIONS Stricture formation after esophageal endoscopic mucosal resection is common. Risk factors for stricture formation include large mucosal resections and the resection of multiple lesions on the initial procedure.

Abstract
Background Stricture formation is one of the major complications after endoscopic removal of large superficial squamous cell neoplasms of the esophagus, and local steroid injections have been adopted to prevent it. However, fundamental pathological alterations related to them have not been well analyzed so far. The aim of this study was to analyze the time course of the healing process of esophageal large mucosal defects resulting in stricture formation and its modification by local steroid injection, using an animal model. Methods Esophageal circumferential mucosal defects were created by endoscopic mucosal dissection (ESD) for four pigs. One pig was sacrificed five minutes after the ESD, and other two pigs were followed-up on endoscopy and sacrificed at the time of one week and three weeks after the ESD, respectively. The remaining one pig was followed-up on endoscopy with five times of local steroid injection and sacrificed at the time of eight weeks after the ESD. The esophageal tissues of all pigs were subjected to pathological analyses. Results For the pigs without steroid injection, the esophageal stricture was completed around three weeks after the ESD on both endoscopy and esophagography. Histopathological examination of the esophageal tissues revealed that spindle-shaped α-smooth muscle actin (SMA)-positive myofibroblasts arranged in a parallel fashion and extending horizontally were identified at the ulcer bed one week after the ESD, and increased contributing to formation of the stenotic luminal ridge covered with the regenerated epithelium three weeks after the ESD. The proper muscle layer of the stricture site was thinned with some myocytes which seemingly showed transition to the myofibroblast layer. By contrast, for the pig with steroid injection, esophageal stricture formation was not evident with limited appearance of the spindle-shaped myofibroblasts, instead, appearance of stellate or polygocal SMA-positive stromal cells arranged haphazardly in the persistent granulation tissue of the ulcer site. Conclusions Proliferation of spindle-shaped myofibroblasts arranged in a parallel fashion is likely to play an important role in stricture formation after circumferential mucosal defects by esophageal ESD, which may be related to the thinning of the proper muscle layer in the healing course of the defects. Local steroid injection seems to be effective to prevent the stricture through the modification of this process.

Abstract
Endoscopic submucosal dissection (ESD) is currently accepted as the major treatment modality for superficial neoplasms in the gastrointestinal tract including the esophagus. An important advantage of ESD is its effectiveness in resecting lesions regardless of their size and severity of fibrosis. Based on excellent outcomes for esophageal neoplasms with a small likelihood of lymph node metastasis, the number of ESD candidates has increased. On the other hand, ESD still requires highly skilled endoscopists due to technical difficulties. To avoid unnecessary complications including perforation and postoperative stricture, the indications for ESD require careful consideration and a full understanding of this modality. This article, in the highlight topic series, provides detailed information on the indication, procedure, outcome, complications and their prevention in ESD of superficial esophageal neoplasms.

Abstract
INTRODUCTION Pharyngo-oesophageal stricturing is common following treatment of head and neck cancers. Absolute dysphagia secondary to total stenosis, although rare, is particularly debilitating and presents a significant therapeutic challenge. We present a strategy for managing total neopharyngeal stenosis following pharyngolaryngo-oesophagectomy (PLOG). PRESENTATION OF CASE A 71-year-old female developed total neopharyngeal stenosis following PLOG with gastric interposition for squamous cell carcinoma of the proximal cervical oesophagus/post-cricoid. A transcervical, percutaneous, radiologically guided procedure was performed to restore lumenal patency, which enabled resumption of oral feeding. DISCUSSION Established treatments for pharyngo-oesophageal strictures are frequently limited by complications in patients with complex strictures or total stenoses. Whilst several interventions have been described, recent interest has focussed on combined antegrade/retrograde endoscopic procedures dilating a pre-existing gastrostomy site for access. This was not possible in our patient due to the surgically altered anatomy which posed a unique therapeutic challenge. CONCLUSION This is the first reported percutaneous, transcervical, radiologically guided technique to treat neopharyngeal stenosis following PLOG. It demonstrates a novel and efficacious approach which may be considered in the management of this rare but significant complication.

Abstract
Background Endoscopic submucosal dissection (ESD) permits removal of esophageal epithelial neoplasms en bloc, but is associated with esophageal stenosis, particularly when ESD involves the entire circumference of the esophageal lumen. We examined the effectiveness of systemic steroid administration for control of postprocedural esophageal stricture after complete circular ESD. Methods Seven patients who underwent wholly circumferential ESD for superficially extended esophageal squamous cell carcinoma were enrolled in this study. In 3 patients, prophylactic endoscopic balloon dilatation (EBD) was started on the third post-ESD day and was performed twice a week for 8 weeks. In 4 patients, oral prednisolone was started with 30 mg daily on the third post-ESD day, tapered gradually (daily 30, 30, 25, 25, 20, 15, 10, 5 mg for 7 days each), and then discontinued at 8 weeks. EBD was used as needed whenever patients complained of dysphagia. Results En bloc ESD with tumor-free margins was safely achieved in all cases. Patients in the prophylactic EBD group required a mean of 32.7 EBD sessions; the postprocedural stricture was dilated up to 18 mm in diameter in these patients. On the other hand, systemic steroid administration substantially reduced or eliminated the need for EBD. Corticosteroid therapy was not associated with any adverse events. Post-ESD esophageal stricture after complete circular ESD was persistent, requiring multiple EBD sessions. Conclusions Use of oral prednisolone administration may be an effective treatment strategy for reducing post-ESD esophageal stricture after complete circular ESD.

Abstract
Apart from typical reflux symptoms and oesophagitis, the clinical presentation of GERD can be dominated by mucosal complications of reflux (Barrett's oesophagus, oesophageal adenocarcinoma, Peptic structure) or by extra-oesophageal syndromes, most notably asthma, laryngitis, or chronic cough. Managing these entities is much less straightforward than with oesophagitis. With respect to adenocarcinoma, metaplasia and dysplasia are recognised precursors, but the potential of these lesions to evolve to cancer has not been shown to lessen as a result of treatment, medical or surgical. Consequently, management focuses on strategies to identify and eliminate high-grade dysplasia and intramucosal cancer, lesions that are potentially curable by endoscopic ablation or surgical resection. With respect to the extra-oesophageal GERD syndromes, these are increasingly recognised as multifactorial conditions with reflux as an exacerbating factor. Treatment trials have been generally disappointing and the clinical challenge remains in accurately identifying afflicted patients who might benefit from more intensive medical or surgical reflux treatment.

Abstract
Aluminum phosphide (AlP) is a lethal solid fumigant pesticide which has been recently linked to esophageal stricture formation. This paper aims to study the clinical profile and response to treatment of AlP-induced esophageal strictures. Data on all patients of AlP-induced strictures seen between January 2004 and June 2008 were retrieved and analyzed for clinical parameters and response to endoscopic dilation. Each patient underwent barium swallow to define the site and length of stricture and then was dilated endoscopically. Twelve patients of AlP-induced esophageal stricture (seven males) with a mean age of 26.83+/-8.43 years were evaluated. They had consumed one to three AlP tablets, 4-156 weeks before reporting to us. They had onset of dysphagia within 2 to 8 weeks of ingestion of AlP. Of 14 strictures in 12 patients, seven were in upper third, two in middle third, and five in lower third of esophagus with a mean length of 1.96+/-0.75 cm. Nine patients responded to dilation requiring 5.56+/-2.65 dilations. Four patients were given intralesional steroids to augment the effect of dilation. Three patients failed and were operated upon. All patients remained symptom free over a follow-up of 3-30 (15.67+/-9.41) months. AlP-induced esophageal strictures can be dilated endoscopically in a majority of patients; however, 25% of them require surgical intervention. AlP-induced esophageal strictures, thus, behave like caustic-induced strictures.

Abstract
Esophageal strictures are a problem frequently encountered by gastroenterologists. Dilation has been the customary treatment for benign esophageal strictures, and dilation techniques have advanced over the years. Depending on their characteristics and the response to treatment, esophageal strictures can be classified into two types: 1, simple (Schatzki rings, webs, peptic injury, and following sclerotherapy) - these are easily amenable to dilation, with a low recurrence rate after initial treatment; and 2, complex (caused by caustic ingestion, radiation injury, anastomotic strictures, and photodynamic therapy) - these are difficult to dilate and are associated with higher recurrence rates. Refractory strictures are those in which it is not possible to relieve the anatomic restriction successfully up to a diameter of 14 mm over five sessions at 2-weekly intervals, due to cicatricial luminal compromise or fibrosis; and recurrent strictures are those in which it is not possible to maintain a satisfactory luminal diameter for 4 wk once the target diameter of 14 mm has been achieved. There are no standard recommendations for the management of refractory strictures. The various techniques used include intralesional steroid injection combined with dilation; endoscopic incisional therapy, with or without dilation; placement of self-expanding metal stents, Polyflex stents, or biodegradable stents; self-bougienage; and endoscopic surgery. This review discusses the indications, technique, results, and complications of the use of intralesional steroid injections combined with dilation and endoscopic incisional therapy with dilation in refractory strictures.

Successful treatment of severe refractory anastomotic stricture in an infant after esophageal atresia repair by endoscopic balloon dilation combined with systemic administration of dexamethasone.

Abstract
A boy with a history of esophageal atresia repair received an esophagoesophagostomy at 14 months for a severe refractory anastomotic stricture, which had already required repeated balloon dilation with intralesional dexamethasone injection. Anastomotic leakage and stricture was again evident after the second surgery, and the patient underwent five procedures of balloon dilations with intralesional dexamethasone injection. Dysphagia was persistent and the patient required dilation every 2-3 weeks. After the sixth dilation, the patient was given 1 mg/kg per day of dexamethasone i.v. for 3 days. Dexamethasone i.v. was tapered during the following 3 days and finished at day 6. A week later, endoscopic findings showed an apparent improvement in the stricture. Another dilation was followed by 1 mg/kg per day dexamethasone i.v. for 7 days, and 0.75 kg/mg per day oral dexamethasone for another 7 days. The stricture improved completely and the anastomosis was patent after the second dilation. The patient is doing well without dysphagia and has not required additional dilation for over 18 months after the last dilation. Balloon dilation in combination with systemic dexamethasone administration may be an effective treatment that could substitute invasive techniques including surgical manipulation for severe refractory strictures.

Abstract
BACKGROUND AND AIMS The aim of the study was to examine whether endoscopic intralesional corticosteroid injection into recalcitrant peptic esophageal strictures reduces the need for repeat stricture dilation. METHODS Patients with a peptic esophageal stricture and recurrent dysphagia having had at least one dilation in the preceding 18 months were enrolled in a prospective randomized, double-blind study comparing steroid and sham injection. After endoscopic confirmation of recurrent stricture, patients were randomized to receive either 0.5 cc/quadrant triamcinolone (40 mg/cc) or sham injection into the stricture followed by balloon dilation of the stricture. Patients were stratified by the number of dilations required in the preceding 18 months, severity of dysphagia, the presence of esophagitis, stricture severity, and prior therapy with a proton-pump inhibitor. Patients and their physicians were blinded to the type of intervention received. Baseline dysphagia questionnaires were completed. Post-procedurally all patients were placed on a standardized proton-pump inhibitor regimen and standardized telephone follow-up questionnaires were completed at 1 wk and at 1, 3, 6, 9, and 12 months. The original sample-size calculation of 60 patients could not be met in a timely fashion because of a low incidence of recalcitrant peptic stricture patients. RESULTS A total of 30 patients were enrolled, 15 in the steroid group (10 men, mean age 66 yr) and 15 in the sham group (11 M, mean age 67 yr). Patients were followed for 1 yr, unless they underwent an antireflux operation or died. Two patients, one per group, died of non-esophageal causes at 1 and 12 months. Four patients had fundoplication, two in each group, unrelated to stricture or dysphagia. Two patients in the steroid group (13%) and nine in the sham group (60%) required repeat dilation (p= 0.011). CONCLUSIONS In patients with recalcitrant peptic esophageal stricture, steroid injection into the stricture combined with acid suppression significantly diminishes both the need for repeat dilation and the average time to repeat dilation compared to sham injection and acid suppression alone.

Abstract
Dysphagia is a common complaint that always warrants investigation. The patient's history and preliminary testing can help differentiate between the two types of dysphagia: oropharyngeal or esophageal. Specific treatments for either of these types of dysphagia depend on the underlying etiology. Oropharyngeal dysphagia is often associated with a neuromuscular disorder and is treated with swallowing rehabilitation. Esophageal dysphagia is usually due to an anatomic defect or a motility disorder. Anatomic defects can often be corrected with endoscopic or surgical procedures. Motility disorders often benefit from pharmacologic treatment. Achalasia may be corrected with an endoscopic procedure with pneumatic dilation or, more recently, with injection of botulinum toxin.
