[PMID: 38649492 DOI: 10.1007/s00464-024-10817-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2023] [Accepted: 03/22/2024] [Indexed: 04/25/2024]
Abstract
BACKGROUND Studies have evaluated the efficacy of endoscopic incisional therapy (EIT) for benign anastomotic strictures. We performed a systematic review and meta-analysis to evaluate stricture recurrence after EIT following esophagectomy or gastrectomy. METHODS A systematic search of databases was performed up to April 2nd, 2023, after selection of key search terms with the research team. Inclusion criteria included human participants undergoing EIT for a benign anastomotic stricture after esophagectomy or gastrectomy, age ≥ 18, and n ≥ 5. Our primary outcome was the incidence of stricture recurrence among patients treated with EIT compared to dilation. Our secondary outcome was the stricture-free duration after EIT and rate of adverse events. Meta-analysis was performed with RevMan 5.4.1 using a Mantel-Haenszel random-effects model. Publication bias was evaluated with funnel plots and the Egger test. RESULTS A total of 2550 unique preliminary studies underwent screening of abstracts and titles. This led to 33 studies which underwent full-text review and five studies met the inclusion criteria. Meta-analysis revealed reduced odds of overall stricture recurrence (OR 0.35, 95% CI 0.13-0.92, p = 0.03; I2 = 71%) and reduced odds of stricture recurrence among naïve strictures (OR 0.32, 95% CI 0.17-0.59, p = 0.0003; I2 = 0%) for patients undergoing EIT compared to dilation. There was no significant difference in the odds of stricture recurrence among recurrent strictures (OR 0.63, 95% CI 0.12-3.28, p = 0.58; I2 = 81%). Meta-analysis revealed a significant increase in the recurrence-free duration (MD 42.76, 95% CI 12.41-73.11, p = 0.006) among patients undergoing EIT compared to dilation. CONCLUSION Current data suggest EIT is associated with reduced odds of stricture recurrence among naïve anastomotic strictures. Large, prospective studies are needed to characterize the safety profile of EIT, address publication bias, and to explore multimodal therapies for refractory strictures.

Abstract
An oesophageal stricture refers to a narrowing of the oesophageal lumen, which may be benign or malignant. The cardinal feature is dysphagia, and this may result from intrinsic oesophageal disease or extrinsic compression. Oesophageal strictures can be further classified as simple or complex depending on stricture length, location, diameter, and underlying aetiology. Many endoscopic options are now available for treating oesophageal strictures including dilatation, injectional therapy, stenting, stricturotomy, and ablation. Self-expanding metal stents have revolutionised the palliation of malignant dysphagia, but oesophageal dilatation with balloon or bougienage remains first-line therapy for most benign strictures. The increase in endoscopic and surgical interventions on the oesophagus has seen more benign refractory oesophageal strictures that are difficult to treat, and often require advanced endoscopic techniques. In this review, we provide a practical overview on the evidence-based management of both benign and malignant oesophageal strictures, including a practical algorithm for managing benign refractory strictures.

The Efficacy and Safety of Treatment Outcomes for Refractory Benign Esophageal Strictures Using a Novel Combination of Needle-Knife Stricturoplasty, Balloon Dilation, and Steroid Injection (with Video). GE PORTUGUESE JOURNAL OF GASTROENTEROLOGY 2024; 31:48-53. [PMID: 38476305 PMCID: PMC10928867 DOI: 10.1159/000527770] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/09/2022] [Accepted: 10/03/2022] [Indexed: 03/14/2024]
Abstract
Background and Aims Benign esophageal strictures often present with dysphagia and can significantly impair a patient's quality of life, especially when refractory to standard endoscopic techniques. When repeat dilations fail to achieve an adequate luminal diameter or resolve dysphagia, further therapy with needle-knife or steroid injections is needed. However, patients can still clinically fail. To manage such strictures, we employed a novel combination of all three techniques. Methods Single-center case series of adult patients with benign strictures that were refractory to conventional endoscopic therapy and removable self-expanding metal stenting. Primary clinical success was defined as complete resolution in dysphagia. Secondary outcomes included periodic dilation index (frequency of dilations over the follow-up time), esophageal diameter changes, technical success, and complications. Results Four patients (median age 49.7 years old, interquartile range [IQR] 30-59) underwent endoscopic therapy for complex, benign strictures using our triple therapy technique. Etiologies of the strictures included peptic strictures (n = 3) and an anastomotic stricture (n = 1). There was 100% technical success rate with no associated adverse events. There was a 50% clinical success rate, with 1 additional patient having partial improvement in dysphagia. The median diameter of the esophagus before and after triple therapy was 3.2 mm (IQR 3.5-5.5) and 12.8 mm (IQR 11.7-14.2), respectively. The periodic dilation index was 6.3 before and 1.5 after triple therapy. The median length of follow-up was 362.5 days. Conclusion Triple combination therapy may be useful in benign strictures that are refractory to standard techniques. Larger studies are needed to validate these findings.

Abstract
Background Due to its nutritional advantages over total gastrectomy, proximal gastrectomy (PG) with anti-reflux techniques has gained significant attention in East Asian countries in recent years. The double flap technique (DFT) and modified side overlap and fundoplication by Yamashita (mSOFY) are two promising anti-reflux interventions following PG. However, anastomotic stenosis after DFT and gastroesophageal reflux after mSOFY have been reported in several patients. To address these concerns, a hybrid reconstruction procedure was designed, namely, right-sided overlap with single flap valvulopasty (ROSF), for proximal gastrectomy, with the aim of reducing anastomotic stricture and reflux. Among the 38 patients who underwent ROSF at our hospital, one developed Stooler grade II anastomotic stenosis. Herein, we present the successful management of this patient through endoscopic stricturotomy (ES). Case summary A 72-year-old female complaining of "epigastric pain and discomfort for more than 1 month" was diagnosed with adenocarcinoma of the esophagogastric junction (Siewert type II). She underwent laparoscopic-assisted PG and ROSF procedures at our hospital and recovered well after surgery. However, she started experiencing progressive difficulty in eating and vomiting approximately 3 weeks after the intervention. Endoscopy revealed Stooler grade II esophagogastric anastomotic stenosis. ES with insulated tip (IT) Knife nano was eventually performed, and the patient was able to resume a normal diet without experiencing any discomfort during the 5-month follow-up period. Conclusion Endoscopic stricturotomy using IT Knife nano successfully treated anastomotic stenosis following ROSF with no associated complications. Thus, ES to treat anastomotic stenosis after PG with valvulopasty can be considered a safe option and should be performed in centers with the required expertise.

Abstract
A 67-year-old male patient with long term gastroesophageal reflux disease (GERD) on double dose proton pump inhibitors, presented with dysphagia for soft foods. He underwent upper gastrointestinal (UGI) endoscopy which revealed a severe regular stricture at the level of the esophagogastric junction with a residual luminal orifice measuring 2 mm. Biopsies at the site of the stricture ruled out malignancy and were suggestive of peptic etiology. The patient underwent twelve endoscopic dilatation sessions, 11 of them with Savary-Guillard bougies and 1 with TTS balloon, up to a maximal diameter of 18 mm, with only partial relief of dysphagia symptoms. Due to the persistence of the stricture and dysphagia symptoms, incisional therapy was performed in two endoscopic sessions at the site of the stricture was performed with a Mori´s knife parallel to the longitudinal axis of the esophagus in a radial manner in all of the quadrants. There were no adverse events. On follow-up, 2 months later after the last session, the patient had a significant improvement and did not have any dysphagia symptoms. UGI endoscopy revealed minimal residual narrowing at the site of the previous stricture in the distal esophagus. He remains asymptomatic after 6 months follow-up.

Abstract
Refractory esophageal anastomotic strictures are a frequent challenge for endoscopists. The current therapeutic strategies have a significant restenosis rate, and patients usually require repeated sessions and suffer from dysphagia. Therefore, we propose a modified method named endoscopic stricturotomy (ES) to treat refractory esophageal anastomotic strictures. The patients diagnosed with refractory esophageal anastomotic strictures were enrolled in the cohort study. The method of ES is to incise longitudinally only a single strip of mucosa at the most prominent part of fibrotic scar and completely cut fibrotic tissues under the mucosa. The primary endpoint was the times of endoscopic therapies. The secondary endpoints include the effective rate, success rate, recurrence rate, endoscopic treatment intervals, complications, length of hospital stay, and surgical cost. The patients were followed up for at least 6 months after ES. The median anastomotic diameter of 12 patients was 2 mm (range 1 to 4 mm). Dysphagia were dramatically relieved in all patients (dysphagia grade from 3 to 1), the effective rate was 100%. During the follow-up, the 12 patients received a total number of 38 sessions, and the median number of ES sessions was 2.5 (1-9), and the success rate were 83%. Nine of the patients (75%) developed restenosis during follow-up, with a median interval of 38 days (15-315 days). No complications occurred during treatment and following up. The median hospital stay was 2 days (2-2.9 days), and the hospitalization costs was 3887.4 RMB (3632.8 RMB-4116.9 RMB). ES seems to be an effective treatment modality for refractory esophageal anastomotic strictures. Large prospective clinical trials are needed to confirm its utility and its place in the management of refractory esophageal anastomotic strictures (ChiCTR2000032997).

Abstract
BACKGROUND Cervical anastomotic strictures after esophagectomy cause significant disease burden. We aimed to study the technical feasibility and safety of intensive endoscopic therapy. METHODS In this pilot study, we included 15 patients with an untreated benign cervical anastomotic stricture after esophagectomy. Intensive endoscopic therapy comprised three endoscopic modalities: in- and excision using a needle-knife, intralesional steroid injections and bougie dilation. In two endoscopic procedures, the stricture was dilated up to a luminal diameter of 18 mm. Patients were followed up to 6 months. RESULTS A luminal diameter of 18 mm was achieved in 13 of 15 patients (87%) after two endoscopic procedures. No major adverse events related to the investigational treatment occurred. Median dysphagia scores significantly improved from 2 (IQR, interquartile range, 2-3) at baseline to 0 (IQR 0-1) after 14 days (p < 0.001). Eleven (73%) patients developed recurrent symptoms of dysphagia requiring a median of 1 (IQR 0-3) additional endoscopic dilation procedure. CONCLUSIONS Achieving a luminal diameter of 18 mm in two procedures with intensive endoscopic therapy was technically feasible and effective in reducing dysphagia rapidly in patients with a cervical anastomotic stricture after esophagectomy. No major adverse events related to the investigational treatment were observed.

Abstract
BACKGROUND AND AIM We aim to evaluate the efficacy and safety of endoscopic radial incision (ERI) versus endoscopic balloon dilation (EBD) treatment of naïve, recurrent, and refractory benign esophageal anastomotic strictures. METHODS One hundred and one ERI, 145 EBD, and 42 ERI combined with EBD sessions were performed in 136 consecutive patients with benign esophageal anastomotic stricture after esophagectomy at Zhongshan Hospital from January 2016 to August 2021. Baseline characteristics, operational procedures, and clinical outcomes data were retrospectively evaluated. Parameters and recurrence-free survival (RFS) were compared between ERI and EBD in patients with naïve or recurrent or refractory strictures. Risk factors for re-stricture after ERI were identified using univariate and multivariate analyses. RESULTS Twenty-nine ERI versus 68 EBD sessions were performed for naïve stricture, 26 ERI versus 60 EBD for recurrent strictures, and 46 ERI versus 17 EBD for refractory stricture. With comparable baseline characteristics, RFS was greater in the ERI than the EBD group for naïve strictures (P = 0.0449). The ERI group had a lower 12-month re-stricture rate than the EBD group (37.9% vs 61.8%, P = 0.0309) and a more prolonged patency time (181.5 ± 263.1 vs 74.5 ± 82.0, P = 0.0233). Between the two interventions, recurrent and refractory strictures had similar RFS (P = 0.0598; P = 0.7668). Multivariate analysis revealed initial ERI treatment was an independent predictive factor for lower re-stricture risk after ERI intervention (odds ratio = 0.047, P = 0.001). Few adverse events were observed after ERI or EBD (3.0% vs 2.1%, P = 0.6918). CONCLUSIONS ERI is associated with lower re-stricture rates with better patency and RFS compared with EBD for naive strictures.

Abstract
Luminal strictures can occur as part of many different gastrointestinal (GI) disorders anywhere along the GI tract and affect all age groups. The end goal of managing any stricture is to re-establish an adequate and durable luminal patency that is sufficient to resolve the presenting clinical symptoms. Treatment options can be generally categorized into medical, endoscopic, and surgical. However, within each of these categories, multiple different options are available. Therefore, choosing the best treatment modality is often challenging and depends on multiple factors including the type, location, and complexity of the stricture, as well as the preference of the treating physician. In this article, we will review the most current literature regarding foregut strictures, particularly esophageal and gastric, beyond dilation.

Comparison of the Efficacy and Safety of Endoscopic Incisional Therapy and Balloon Dilatation for Esophageal Anastomotic Stricture. J Gastrointest Surg 2021; 25:1690-1695. [PMID: 33051806 DOI: 10.1007/s11605-020-04811-3] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/30/2020] [Accepted: 09/26/2020] [Indexed: 02/07/2023]
Abstract
BACKGROUND Benign esophageal anastomotic strictures have typically been treated using endoscopic methods, often with balloon dilatation (BD). However, recurrent esophageal strictures after BD have been reported. We evaluated the efficacy and safety of endoscopic incisional therapy (EIT) and BD for treating an anastomotic stricture after a total gastrectomy. METHODS Subjects who underwent EIT or BD as a first treatment for esophagojejunostomy anastomotic stricture after a total gastrectomy between January 2010 and December 2018 were eligible. The medical records of these cases were retrospectively reviewed. Stricture was defined as an inability to pass a normal diameter endoscope (10.2 mm). The stricture area was incised under direct vision with the nano-insulated-tip knife in a radial fashion parallel to the longitudinal axis of the esophagus. RESULTS Twenty-one patients in our database presented with benign anastomotic stricture after a total gastrectomy for advanced gastric cancer. The BD group included 12 patients. The remaining nine patients underwent EIT, and three of these cases received an immediate additional BD. The re-stricture rate was significantly different between the BD and EIT groups (41.7% vs. 0%, respectively; P = 0.045). There were no significant differences in procedure time, interval from surgery to first stricture, hospitalization period, or complication rates between the groups. One patient developed a microperforation during BD and was treated without surgical intervention. CONCLUSIONS EIT is a safe and effective primary treatment modality compared with BD for esophagojejunostomy anastomotic stricture after a total gastrectomy as it shows a significantly lower re-stricture rate.

Abstract
BACKGROUND AND AIM Endoscopic balloon dilation (EBD) is effective for esophageal stenosis caused by ESD. However, an efficient EBD method has not been established. We, therefore, conducted EBD experiments on porcine esophageal stenosis models. METHODS Study 1: in dilation models (day 22 after ESD), the thickness of the outer muscle layer (as an index of the extension effect) and the area of muscle fiber bundle necrosis in the inner muscle layer (as an index of thermal damage) were evaluated. Study 2: in restenosis models (day 43 after ESD), the thickness of the fibrous plexus (as an index of restenosis) was evaluated. In total, 12 porcine models were created. RESULTS Study 1: the thickness of the outer muscle layer was 1243 ± 322 μm in surrounding locations and it was 803 ± 145 μm beneath the laceration (p = 0.005). In cases of muscular layer injury, the area of necrosis was 15,500 ± 10400 μm2 in surrounding locations and it was 40,200 ± 12900 μm2 at the laceration site (p < 0.001). Study 2: the thickness of the fibrous plexus was 1359 ± 196 μm in surrounding locations and it was 1322 ± 136 μm2 in the laceration scar site (p = 0.74). CONCLUSION Since thermal damage persists until the completion of stenosis, EBD in the initial stage should be carefully performed. An extension effect was observed only at the laceration site and it later returned to a status similar to that of surrounding locations. Additional intervention would be required for preventing restenosis.

Endoscopic Management of Refractory Benign Esophageal Strictures. Dysphagia 2021; 36:504-516.

Abstract
Benign esophageal strictures are commonly encountered in clinical practice. The principal etiologies of benign esophageal strictures include long term acid reflux, caustic injuries, eosinophilic esophagitis, anastomotic strictures or endoscopic therapy. Dysphagia is most prominently present in esophageal strictures along with a variety of other symptoms which depend on the stricture etiology. Benign esophageal strictures can be categorized into two groups: simple or complex depending on their structure. Most strictures can be treated successfully with endoscopic dilation by bougies or balloons dilators. In some cases, treatment is more challenging, involving a higher risk of the patient developing recurrent or refractory strictures. To improve symptoms in these patients, other endoscopic treatments such as steroid injection, incisional therapy and stent placement should be considered. In this manuscript, we provide a comprehensive review of the main treatment options currently available to manage recurrent benign esophageal strictures.

Abstract
INTRODUCTION In patients with benign and refractory esophageal strictures (BES), repeating initial dilations in short intervals could be recommended, but little data are available to validate this strategy. Our aim was to evaluate long-term results of a scheduled program of repeated and sustained esophageal dilations in patients with refractory strictures. METHODS Patients with BES requiring five or more dilations were retrospectively included and divided in two groups for analysis: a SCHEDULED group (SDG) where patients were systematically rescheduled for the 5 first dilations; ON-DEMAND group (ODG) where patients were dilated only in case of recurrence of the dysphagia. Comparison between SDG and ODG was done with a 1:1 matching analysis and etiology of stricture. Clinical success was defined as the absence of dysphagia for more than a year. RESULTS 39 patients with refractory BES were included with post-operative stenosis in 51.2% and post-caustic injury 28.2%; 10 were in SDG and 29 in ODG. In overall analysis (39 patients), the follow-up was 64.4 ± 32 months, success rate was 79.5% and duration of treatment was 27.3 ± 20 months, and mean number of dilations was 11.7 per patient. The need for dilations decreased significantly after 18 months of treatment with an average of 0.56 dilations per semester. Self-expandable metallic stent insertion was associated with an increased rate of complications (5.9% vs 59.1% p = 0.001). In matched analysis (10 ODG vs 10 SDG patients), the duration of treatment was lower in SDG (18.8 vs 41.4 months, p = 0,032) with a higher probability of remission (survival analysis, Log-rank: p = 0,019) and the success rate did not differ between ODG and SDG patients (80% vs 90%; NS). CONCLUSION Overall, long-term esophageal dilations resulted in a 79.5% success rate and the need for further dilatations decreased significantly in both groups after 18-month follow-up. A scheduled dilation program was associated with a higher probability of final success and lower treatment duration.

Abstract
Benign esophageal strictures are one of the common clinical conditions managed by endoscopists. Nearly 90% of the benign esophageal strictures respond to endoscopic dilation. However, a small percentage of patients progress to recalcitrant strictures. The benign recalcitrant esophageal strictures are difficult to manage both medically and endoscopically as they do not respond to conventional treatment with proton pump inhibitors and esophageal dilations. Patients with benign recalcitrant esophageal strictures are at a high risk of developing debilitating malnutrition and morbidity due to severe dysphagia. This condition is associated with psychological trauma to patients as treatments are usually prolonged with poor outcomes. Also, this can be a financial burden on the healthcare industry due to several sessions of treatment. In this article, we discuss the classification of benign esophageal strictures, evidence-based treatment strategies, endoscopic procedural techniques, and complications of endoscopic interventions. We aim to guide providers in managing benign esophageal strictures with a focus on endoscopic management of benign recalcitrant esophageal strictures.

Utility of radial incision and cutting with steroid injection for refractory stricture after endoscopic submucosal dissection for large superficial esophageal squamous cell carcinoma. Surg Endosc 2021; 35:6930-6937. [PMID: 33398559 DOI: 10.1007/s00464-020-08204-0] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2020] [Accepted: 12/02/2020] [Indexed: 10/22/2022]
Abstract
BACKGROUND AND AIMS Endoscopic submucosal dissection (ESD) for superficial esophagus squamous cell carcinoma (SESCC) may cause esophageal stricture and related dysphagia symptoms, especially when the lesion is widespread. Endoscopic balloon dilation (EBD) is the prior choice to treat post-ESD stricture. However, certain patients show poor response to EBD treatment and frequent dilations are required. We perform radial incision and cutting combined with intralesional steroid injection to manage refractory stricture. The study aims to evaluate the safety and efficacy of this new combined treatment. METHODS From October 2017 to February 2019, 25 patients who accepted repeated EBD because of refractory stricture after extensive ESD for large SESCC were enrolled. Radial incision and cutting followed by local steroid injection was performed on all the patients, and therapeutic EBD was conducted to treat recurring stricture after combined treatment. The incidence of recurrent stricture, clinical outcome of combined treatment, and following therapeutic EBD, procedure-related adverse events were assessed and analyzed. RESULTS During the follow-ups, the incidence of recurrent esophageal strictures was 92%. Combined treatment reduced the severity of stenosis and lowered the corresponding dysphagia scores significantly, compared with previous EBD. Mean symptom-relief duration of EBD was prolonged significantly from 29.9 to 76.0 days. Perforation was observed in one patient during operation and successfully sealed with metal clips. CONCLUSIONS Combination of radial incision and cutting with steroid injection is a safe and feasible treatment for esophageal refractory stricture after extensive ESD, appearing to improve the therapeutic EBD outcome and maintain a longer symptom-relief duration.

Abstract
BACKGROUND Post-esophagectomy anastomotic strictures are difficult to treat. The impact of adding local steroid injection to endoscopic dilation for the treatment of post-esophagectomy anastomotic strictures is unclear. We conducted a systematic review and meta-analysis to assess the efficacy of performing steroid injection in addition to dilation. METHODS A search was conducted in MEDLINE, Cochrane Library, EMBASE, and Web of Science from inception to January 2019. Randomized controlled trials (RCTs) comparing the efficacy of endoscopic dilation plus either local steroid injection (steroid group) or saline injection (placebo group) were included in the analysis. RESULTS Three RCTs were eligible for the final analysis: 72 patients (mean age 61.3 years, 74 % male) in the steroid group and 72 patients (mean age 59.6 years, 71 % male) in the placebo group. The mean number of dilations required to resolve the stricture was significantly lower in the steroid group compared with the placebo group, with a mean weighted difference of -1.62 (95 % confidence interval [CI] -2.73 to -0.50; P = 0.004). After 6 months of follow-up, there was a trend toward more patients in the steroid group remaining dysphagia free compared with the placebo group, with a pooled odds ratio of 2.36 (95 %CI 0.94 to 5.91; P = 0.07, I2 = 24 %). CONCLUSION This meta-analysis showed that the addition of local steroid injection at the time of dilation for benign anastomotic strictures led to a significant decrease in the number of procedures required to resolve the stricture and may well reduce dysphagia symptoms during follow-up.

Abstract
This review attempts to present the available evidence regarding the use of biodegradable stents in refractory benign esophageal strictures, especially highlighting their impact on clinical success and complications. A comprehensive literature search was conducted in PubMed, using the terms "biodegradable" and "benign"; evidence from cohort and comparative studies, as well as data from one pooled analysis and one meta-analysis are presented. In summary, the results from these studies indicate that the effectiveness of biodegradable stents ranges from more than one third to a quarter of cases, fairly similar to other types of stents used for the same indication. However, their implementation may reduce the need for re-intervention during follow up. Biodegradable stents also seem to reduce the need for additional types of endoscopic therapeutic modalities, mostly balloon or bougie dilations. Results from pooled data are consistent, showing moderate efficacy along with a higher complication rate. Nonetheless, the validity of these results is questionable, given the heterogeneity of the studies included. Finally, adverse events may occur at a higher rate but are most often minor. The lack of high-quality studies with sufficient patient numbers mandates further studies, preferably randomized, to elucidate the exact role of biodegradable stents in the treatment of refractory benign esophageal strictures.

Abstract
INTRODUCTION Benign gastrointestinal strictures are common, and can be congenital or acquired (anastomotic, corrosive, induced by Crohn's disease or endoscopic treatments, etc.). Patients usually present with stricture-related symptoms such as vomiting, dysphagia, dyschezia, abdominal pain, which impair their quality of life. Endoscopic balloon dilation (EBD) is the first-line treatment for most of the benign strictures; however, long-term efficacy is suboptimal, and the recurrence rate can be up to 38%. Endoscopic incision (EI) was firstly reported for treatment of congenital membranous stricture, and then applied to other benign gastrointestinal strictures. AREA COVERED In the present review, we provided a comprehensive review of EI for the treatment of benign gastrointestinal strictures, mainly focus on the technical details, indication, safety, and efficacy of EI. The present review is expected to provide tips for operators who are going to perform EI. EXPERT OPINION EI can serve as an alternative method for treatment of gastrointestinal strictures, the best indications are congenital membranous stricture and short-segmental (<1 cm) anastomotic strictures refractory to EBD. EI may also be attempted for strictures induced by other reasons. Combination with other endoscopic methods such as EBD, local steroid injection, stent placement, may improve the efficacy of EI.

Abstract
BACKGROUND AND AIMS Endoscopic dilation (ED) is still the mainstay of therapeutic management of benign esophageal strictures (BESs). This study aimed to establish risk factors for refractory BESs and assess long-term clinical outcomes of ED. METHODS We performed a retrospective study in 891 patients who underwent ED from 2003 to 2018 for BESs. We searched electronic medical records in 6 tertiary care centers in the Netherlands for data on clinical outcome of ED. Median follow-up was 39 months. The primary endpoint was risk factors for refractory BESs, defined as factors associated with an increased number of ED sessions during follow-up. Secondary endpoints were time from first to last ED session and adverse events. RESULTS Dilation up to 13 to 15 mm was associated with a higher number of ED sessions than dilation up to 16 to 18 mm (5.0 vs 4.1; hazard ratio [HR], 1.4; P = .001). Compared with peptic strictures, anastomotic (4.9 vs 3.6; HR, 2.1; P < .001), radiation (5.0 vs 3.6; HR, 3.0; P < .001), caustic (7.2 vs 3.6; HR, 2.7; P < .001), and postendotherapy (3.9 vs 3.6; HR, 1.8; P = .005) strictures were associated with a higher number of ED sessions. After 1 year of follow-up, the proportions of patients who remained free of ED was 75% in anastomotic, 71% in radiation, 70% in peptic, 83% in postendotherapy, and 62% in caustic strictures. Esophageal perforation occurred in 23 ED sessions (.4%) in 22 patients (2.4%). CONCLUSIONS More than 60% of patients with BESs remain free of ED after 1 year of follow-up. Because dilation up to 16 to 18 mm diameter was associated with fewer ED sessions during follow-up, we suggest that clinicians should consider dilation up to at least 16 mm to reduce the number of ED sessions in these patients.

Abstract
PURPOSE OF REVIEW With a globally aging population, dysphagia is a growing health concern among elderly. Increasing reflux disease has contributed to an increased prevalence of dysphagia from peptic strictures and esophageal cancer. Dysphagia can lead to malnutrition and aspiration pneumonia, causing considerable morbidity and mortality. This review article focuses on recent advances in the approach and management of esophageal dysphagia. RECENT FINDINGS Endoscopic functional luminal imaging probe is a novel test that complements upper endoscopy, esophagram, and esophageal manometry for evaluation of esophageal dysphagia. Opioid induced esophageal dysfunction (OIED) is an emerging clinical entity that can mimic achalasia. Strictures refractory to dilation can be treated with intralesional steroid injections, electrosurgical incision, or esophageal stents. Peroral endoscopic myotomy (POEM) is gaining in popularity for treatment of achalasia and other spastic disorders of esophagus. Treatment of esophageal dysphagia may include proton pump inhibitors, endoscopic dilation, or surgery and requires a personalized approach based on risks and benefits. POEM is a valuable therapy for achalasia, but further studies are needed to evaluate its use, and other alternatives, for treatment of OIED and spastic esophageal disorders.

Abstract
BACKGROUND Refractory benign gastrointestinal (GI) strictures are difficult to treat and placement of a stent is a commonly sought resort. Stents used for this purpose are fully covered self-expanding metal stent (FCSEMS), a biodegradable stent (BDS) and recently, a lumen-apposing metal stent (LAMS). There is no data comparing these stents to this end. METHODS We conducted a comprehensive search of multiple electronic databases and conference proceedings (from inception through October 2018) to identify studies that reported on the performance of FCSEMS, BDS, and LAMS in the treatment of refractory benign GI strictures. Our goals were to evaluate the pooled rate of technical success, clinical success, and adverse events with these stents and compare the outcomes between them. RESULTS A total of 31 studies were analyzed. In total, 14 (342 patients), 11 (226 patients), and 8 studies (192 patients) reported the use of FCSEMS, BDS, and LAMS, respectively. The pooled rate of technical success was 96.5% [95% confidence interval (CI): 93.5-98.1], 91.9% (95% CI: 85.6-95.6), and 97.6% (95% CI: 94.0-99.0) with FCSEMS, BDS, and LAMS respectively. No statistical significance to the difference was noted. The pooled rate of clinical success was 48.4% (95% CI: 37.1-59.8), 34.9% (95% CI: 23.6-48.1), and 78.8% (95% CI: 65.8-87.8) with FCSEMS, BDS, and LAMS, respectively. Statistical significance was noted in LAMS versus FCSEMS (P=0.001) and LAMS versus BDS (P=0.001). LAMS demonstrated statistically better outcomes in regards to stent migration and postprocedure pain when compared with FCSEMS and BDS. CONCLUSION Our study demonstrates that LAMS gives better clinical outcomes in the treatment of refractory benign GI strictures when compared with FCSEMS and BDS. Variability in the site, as well as the length of stricture, indirect comparison, and heterogeneity, were the limitations of our study.

Abstract
Esophageal anastomotic strictures are a non-negligible cause of benign strictures and secondary dysphagia. It should be noted that these are often complex strictures, with a large ischemic-fibrotic component. Thus, they are difficult to treat due to their recurrence, despite endoscopic dilation. Endoscopic incisional therapy appears as a therapeutic alternative in this type of patient, which allows the elimination of the stenotic ring, with a good efficacy and safety profile. We present the case of a patient with postoperative esophageal strictures refractory to treatment with dilation and endoscopic prosthesis, who was finally satisfactorily treated with incisional therapy.

Abstract
Refractory benign oesophageal strictures are an infrequent presentation but a cause of significant morbidity and mortality. The treatment of these strictures has changed little in recent years, yet new evidence is emerging for the optimal timing and application of different therapies. In this article, we have carefully reviewed the current literature on the evaluation and management of refractory strictures and provided practical advice as to their management. A number of areas require attention in future research, including carefully designed randomised trials of endoscopic and medical therapies, and a focus on risk factors at a patient and molecular level to facilitate development of medical therapies that can reduce recurrent fibrosis in these patients.

Abstract
OBJECTIVE Endoscopic balloon dilation (EBD) is a standard treatment for anastomotic strictures after esophagectomy, and requires multiple dilations. We conducted a randomized controlled trial to assess the efficacy of adding a steroid injection to EBD to reduce restricture. METHODS Patients were randomized to receive EBD combined with either triamcinolone or placebo injection. The primary endpoint was the number of dilations required to resolve the stricture. The secondary endpoints were restricture-free survival and adverse events. Patients with a dysphagia symptom score of ≥2 after esophagectomy with an endoscopy-confirmed anastomotic stricture were included. A total of 50 mg of triamcinolone acetonide (50 mg/5 mL) or an identical volume of normal saline solution as a placebo was injected per site using a 25-gauge needle immediately after EBD. Both the patient and treating physician were blinded to the treatment given. RESULTS During the 4-year study period, 65 patients were randomized to either the steroid group (n = 33) or placebo group (n = 32). The median number of EBDs required to resolve strictures was 2.0 (interquartile range, 1.0-2.5) in the steroid group and 4.0 (interquartile range, 2.0-6.8) in the placebo group (p < 0.001). After 6 months of follow-up, 39% of patients who had received steroid injections remained recurrence free compared with 16% of those who had received saline injections (p = 0.002). No adverse events occurred during follow-up. CONCLUSIONS Steroid injection shows promising results for the prevention of stricture recurrence in patients who underwent EBD for anastomotic strictures.

Endoscopic Electrocautery Incisional Therapy as a Treatment for Refractory Benign Pediatric Esophageal Strictures. J Pediatr Gastroenterol Nutr 2018; 67:464-468.

Abstract
BACKGROUND AND AIM Refractory esophageal strictures are rare conditions in pediatrics, and are often due to anastomotic, congenital, or caustic strictures. Traditional treatment options include serial dilation and surgical stricture resection; endoscopic intralesional steroid injections, mitomycin C, and externally removable stents combined with dilation have had variable success rates. Although not as widely used, endoscopic electrocautery incisional therapy (EIT) has been reported as an alternative treatment for refractory strictures in a small number of adult series. The aim of the study was to evaluate the safety and efficacy of EIT in a pediatric population with refractory esophageal strictures. METHODS A retrospective chart review was conducted on all patients who underwent EIT for esophageal strictures (May 2011-September 2017) at our tertiary-care referral center. A total of 57 patients underwent EIT. Procedural success was defined as no stricture resection, appropriate diameter for age, and fewer than 7 dilations within 24 months of first EIT session. This corresponded to the 90th percentile of the observed number of dilations in the data. All patients included in the study had at least 2-year follow-up. RESULTS A total of 133 EIT sessions on 58 distinct anastomotic strictures were performed on 57 patients (24 girls). The youngest patient to have EIT was 3 months old and 4.8 kg. There were 36 strictures that met the criteria for refractory stricture and 22 non-refractory (NR) strictures. The median number of dilations before EIT therapy was 8 (interquartile range [IQR]: 6-10) in the refractory group and 3 (IQR: 0-3) in the NR group. In the refractory group, 61% of the patients met the criteria for treatment success. The median number of dilations within 2 years of EIT in the refractory group was 2 (IQR: 0-4). In the NR group, 100% of the patients met criteria for success. The median number of dilations within 2 years of EIT in the NR was 1 (IQR: 0-2). The overall adverse event rate was 5.3% (7/133), with 3 major (2.3%) and 4 minor events (3%). CONCLUSIONS EIT shows promise as an adjunct treatment option for pediatric refractory esophageal strictures and may be considered before surgical resection even in severe cases. The complication rate, albeit low, is significant, and EIT should only be considered by experienced endoscopists in close consultation with surgery. Further prospective longitudinal studies are needed to validate this treatment.

Abstract
These are updated guidelines which supersede the original version published in 2004. This work has been endorsed by the Clinical Services and Standards Committee of the British Society of Gastroenterology (BSG) under the auspices of the oesophageal section of the BSG. The original guidelines have undergone extensive revision by the 16 members of the Guideline Development Group with representation from individuals across all relevant disciplines, including the Heartburn Cancer UK charity, a nursing representative and a patient representative. The methodological rigour and transparency of the guideline development processes were appraised using the revised Appraisal of Guidelines for Research and Evaluation (AGREE II) tool.Dilatation of the oesophagus is a relatively high-risk intervention, and is required by an increasing range of disease states. Moreover, there is scarcity of evidence in the literature to guide clinicians on how to safely perform this procedure. These guidelines deal specifically with the dilatation procedure using balloon or bougie devices as a primary treatment strategy for non-malignant narrowing of the oesophagus. The use of stents is outside the remit of this paper; however, for cases of dilatation failure, alternative techniques-including stents-will be listed. The guideline is divided into the following subheadings: (1) patient preparation; (2) the dilatation procedure; (3) aftercare and (4) disease-specific considerations. A systematic literature search was performed. The Grading of Recommendations Assessment, Develop-ment and Evaluation (GRADE) tool was used to evaluate the quality of evidence and decide on the strength of recommendations made.

Abstract
OPINION STATEMENT PURPOSE OF REVIEW: Esophageal stents are used in clinical practice for endoscopic treatment of a wide variety of esophageal diseases and conditions. This review provides key principles and a literature update on the utility and limitations of esophageal stenting in clinical practice. RECENT FINDINGS Indications for esophageal stenting can be subdivided into two groups. The first group consists of patients with malignant or benign dysphagia, in which an esophageal stent restores luminal patency. In the past years, temporary stent placement has increasingly been used in the therapeutic management of refractory benign esophageal strictures. When endoscopic repeated bougie dilation and other endoscopic treatment modalities have failed, an esophageal stent could be considered. Based on the literature, a fully covered self-expandable metal stent may be the preferred choice for the treatment of both malignant and benign dysphagia. The second group consists of patients with leakage from the esophageal lumen into the surrounding tissue. Esophageal leakage can be subdivided into three forms, benign esophageal perforations (iatrogenic and spontaneous), anastomotic leakage after reconstructive esophageal surgery, and fistula. In a carefully selected group of patients, a covered esophageal stent may be used for sealing off the leakage, thereby preventing further contamination of the tissue surrounding the defect. The past few years, several validated prediction tools have been developed that may assist clinicians in the selection of patients eligible for esophageal stent placement. Based on retrospective studies and expert opinion, a partially or fully covered self-expandable metal stent may have a role in treatment of esophageal leakage. Research do date supports the utilization of esophageal stents for the treatment of malignant or benign dysphagia and esophageal leakage.

Abstract
Background/Aims Dysphagia due to benign pharyngoesophageal strictures (PES) often requires repeated dilations; however, a uniform definition for the therapeutic efficacy of this technique has not been yet established. We aimed to assess the overall efficacy of endoscopic dilation of pharyngoesophageal anastomotic or post-radiotherapy (post-RT) strictures. Methods The data of 48 patients with post-RT (n = 29) or anastomotic PES (n = 19) submitted to endoscopic dilation during a 3-year period were retrospectively assessed. The Kochman criteria were used to determine refractoriness and recurrence. Patients were asked to answer a questionnaire determining prospectively the dilation program efficacy as (a) dysphagia improvement, (b) dysphagia resolution, (c) need for further dilations, or (d) percutaneous endoscopic gastrostomy (PEG) during the previous 6 months. Need for additional therapy was considered an inefficacy criterion. Results The median number of dilations per patient was 4 (total of 296 dilations) with a median follow-up of 29 months. The mean predilation dysphagia Mellow-Pinkas score was 3 and the initial stenosis diameter was 7 mm. Fifteen and 29% of patients presented with the Kochman criteria for refractory and recurrent strictures, respectively. Moreover, 96 and 60% showed dysphagia improvement and resolution, respectively. Seventy-five-percent did not require dilations during 6 months, and 89% did not require PEG. From the patients' perspective, overall efficacy was achieved in 58% of cases. Nine additional therapies were required. Number of dilations (OR 0.7), stricture diameter (OR 2.2), and nonrecurrence criteria (OR 14.2) appeared as significant predictors of overall efficacy, whereas refractory stenosis criteria did not. Conclusions Endoscopic dilation seems to be effective for patients with dysphagia after RT or surgery, especially when assessed as patient perception of improvement. Narrow strictures, recurrent ones, and strictures requiring a higher number of dilations may predict worse outcomes. Key Message Health professionals should establish well-defined efficacy criteria for dilations and base their decision beyond exclusively objective measurements.

Abstract
PURPOSE OF REVIEW This paper presents the author's approach to esophageal dilation. It offers a tailored approach to the application of dilation to specific types of esophageal stenotic lesions. RECENT FINDINGS In patients with inflammatory stricture, recent studies confirm the importance of treating the underlying inflammatory condition in order to decrease the rate of recurrence. The paper reviews some of the novel techniques that have been suggested for the treatment of refractory benign esophageal strictures, including incisional therapy, stenting, or the injection steroids or antifibrotic agents. The endoscopist who treats esophageal strictures must be familiar with the tools of the dilation and how they are best applied to specific types of stenotic lesions. If inflammation is present, effective management requires treatment of the inflammatory process in addition to mechanical dilation of the stenotic lesion. Controlled trials of novel approaches to treatment of refractory benign esophageal strictures are limited and will be necessary to determine efficacy.

Abstract
Self-expandable metal stents (SEMSs) are used for the management of certain esophageal conditions such as strictures, perforations, and fistulae. These can be placed using fluoroscopic control, endoscopic control, or a combination of both. We evaluated our institutional experience of placing a SEMS using only endoscopy without the aid of fluoroscopy to determine safety and feasibility using this technique. A retrospective review was performed to identify all patients who underwent esophageal SEMS from January 2010 to June 2015. Placement of SEMS was accomplished under direct endoscopic visualization without the aid of fluoroscopy. Esophageal lesion was initially identified during endoscopy and a fully covered SEMS was passed over the guide wire and deployed under direct vision. Misplacement of the SEMS during the procedure that required replacement with another new SEMS was considered as a failed procedure. Other periprocedural complications caused by placement of SEMS were noted. A total of 172 patients underwent 280 procedures for SEMS placement. Mean age was 66 years. The most common indication for SEMS placement was stricture in 248 (88%) procedures. Periprocedure SEMS misplacement occurred in 12 (4%) patients. However, only 8 (3%) patients needed to have a new SEMS placed during the same procedure. A total of 64 (23%) patients had migration of SEMS. There were no other periprocedure complications leading to adverse events. Self-expandable metal stent can be placed accurately and safely under direct endoscopic visualization without the aid of fluoroscopy.

Abstract
Background/Aims Benign esophageal stricture after esophagectomy is not an infrequent complication. Anastomotic esophageal stricture requires frequent multiple dilations. We aimed to evaluate the clinical outcomes of dilation therapies using an endoscopic balloon or bougie dilator and analyzed the risk factors associated with refractory stricture. Methods Between January 2009 and May 2016, the medical records of 21 patients treated with endoscopic balloon dilation or bougie dilation for esophageal anastomotic strictures were retrospectively reviewed. Results During the study periods, a total of 21 patients were diagnosed with esophageal anastomotic stricture and included for analysis (17 male; mean age, 68.2±7.2 years at the first procedure). The mean stricture length was 6.4±8.1 mm. The refractory stricture was found in 28.6% of patients, and successful relief of dysphagia was achieved in 71.4% of patients. The major complication associated with dilations was absent. Factors associated with refractory stricture were stricture length (> 10 mm, p<0.049) and diabetes mellitus (p=0.035). Additive bougie dilations achieved clinical success in 4 out of 7 patients. Conclusions Dilation with endoscopic balloon or bougie dilator was an effective and safe procedure for benign anastomotic esophageal strictures of less than 10 mm in length.

Abstract
Improved surgical techniques, as well as preoperative and postoperative care, have dramatically changed survival of children with esophageal atresia (EA) over the last decades. Nowadays, we are increasingly seeing EA patients experiencing significant short- and long-term gastrointestinal morbidities. Anastomotic stricture (AS) is the most common complication following operative repair. An esophageal stricture is defined as an intrinsic luminal narrowing in a clinically symptomatic patient, but no symptoms are sensitive or specific enough to diagnose an AS. This review aims to provide a comprehensive view of AS in EA children. Given the lack of evidence-based data, we critically analyzed significant studies on children and adults, including comments on benign strictures with other etiologies. Despite there is no consensus about the goal of the luminal diameter based on the patient's age, esophageal contrast study, and/or endoscopy are recommended to assess the degree of the narrowing. A high variability in incidence of ASs is reported in literature, depending on different definitions of AS and on a great number of pre-, intra-, and postoperative risk factor influencing the anastomosis outcome. The presence of a long gap between the two esophageal ends, with consequent anastomotic tension, is determinant for stricture formation and its response to treatment. The cornerstone of treatment is endoscopic dilation, whose primary aims are to achieve symptom relief, allow age-appropriate capacity for oral feeding, and reduce the risk of pulmonary aspiration. No clear advantage of either balloon or bougie dilator has been demonstrated; therefore, the choice is based on operator experience and comfort with the equipment. Retrospective evidences suggest that selective dilatations (performed only in symptomatic patients) results in significantly less number of dilatation sessions than routine dilations (performed to prevent symptoms) with equal long-term outcomes. The response to dilation treatment is variable, and some patients may experience recurrent and refractory ASs. Adjunctive treatments have been used, including local injection of steroids, topical application of mitomycin C, and esophageal stenting, but long-term studies are needed to prove their efficacy and safety. Stricture resection or esophageal replacement with an interposition graft remains options for AS refractory to conservative treatments.

Abstract
Benign esophageal strictures arise from various etiologies and are frequently encountered. Although endoscopic dilation is still the first-line therapy, recurrent strictures do occur in approximately 10% of the cases and remains a challenge to gastroenterologists. Areas covered: A literature search was performed using PubMed and Google Scholar databases for original and review articles on endoscopic treatment of benign esophageal strictures. This review outlines the main available treatment options and its controversies in the management of refractory benign esophageal strictures. Expert commentary: Adding local steroid injections to dilation can be effective for peptic stenosis and strictures after endoscopic submucosal dissection, but remains uncertain for anastomotic strictures. Intralesional injections of mitomycin-C could be useful in corrosive strictures. Incisional therapy can be a reliable alternative in Schatzki rings and in anastomotic strictures, in experienced hands. By contrast, long-term outcome with endoprosthetic treatment is disappointing, and stent placement should be carefully considered and individualized.

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
The reported incidence of anastomotic stricture after esophageal atresia repair has varied in case series from as low as 9% to as high as 80%. The cornerstone of esophageal stricture treatment is dilation with either balloon or bougie. The goal of esophageal dilation is to increase the luminal diameter of the esophagus while also improving dysphagia symptoms. Once a stricture becomes refractory to esophageal dilation, there are several treatment therapies available as adjuncts to dilation therapy. These therapies include intralesional steroid injection, mitomycin C, esophageal stent placement, and endoscopic incisional therapy.

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
Leaks are the most frequent early postoperative complication in the two most popular bariatric procedures, Roux-en-Y gastric bypass (RYGB) and laparoscopic sleeve gastrectomy. Multimodal therapy based on self-expandable stent insertion 'to cover' the defect is the most widely documented technique to date with a reported success rate >80%. Additional experimental techniques 'to close' the defect or 'to drain' the paradigestive cavity have been reported with encouraging results. The role of endoscopy in early postoperative bleeding is limited to management of bleeds arising from fresh sutures and the diagnosis of chronic sources of bleeding such as marginal ulcer after RYGB. Post-RYGB stricture is a more delayed complication than leaks and the role of endoscopic dilation as a first-line treatment in this indication is well documented. Ring and band placement are outdated procedures for obesity treatment, but might still be an indication for endoscopic removal, a technique which does not compromise further surgery, if needed.

Abstract
BACKGROUND AND AIMS Refractory benign gastrointestinal (GI) strictures represent a difficult management problem given the limited therapeutic interventions available. We performed a systematic review of all published cases using mitomycin C in the treatment of GI strictures. METHODS Searches of MEDLINE and Embase databases were performed to identify studies reporting application of mitomycin C for GI strictures. Review of titles/abstracts, full review of potentially relevant studies, and data abstraction were performed independently by 2 authors. RESULTS Of 549 citations, 24 studies with 145 patients (74% pediatric and 26% adult) met inclusion criteria. Esophageal strictures were the most common (79%) site of refractory strictures treated with mitomycin C, with caustic injury the most common underlying etiology. The concentration (range, 0.1 to 2 mg/mL; median, 0.4 mg/mL), number of applications (range, 1 to 12; median, 1), duration of applications (range, 1 to 5; median, 2 min), and technique of application (cotton pledget, spray, injection, special catheters) varied among studies. Ninety-one patients (73%; children: 80%, adults: 59%) had a complete response; 26 (21%) had a partial response. Only 1 (0.7%) adverse event was reported: cutaneous sclerosis attributed to microperforation and mitomycin C extravastion after injection. Mean follow-up was 23 (4 to 60) months. CONCLUSIONS Local mitomycin C application seems to be a safe and effective therapy for benign refractory GI strictures of varying etiology in both pediatric and adult populations. Although the results of this systematic review are highly encouraging, it should be considered investigational. Additional randomized trials and larger prospective studies are needed to confirm these results and to better define the optimal dose, concentration, duration and technique of mitomycin C application.

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
OBJECTIVE The aim of this study was to evaluate the safety and efficacy of intramuscular injection of either mitomycin C or dexamethasone with endoscopic dilation for benign esophageal strictures after esophageal surgery or endoscopic submucosal dissection. METHODS Patients with benign esophageal strictures were retrospectively enrolled in this study and divided into three groups: mitomycin C group (mitomycin C injection with endoscopic dilation, dexamethasone group (dexamethasone injection and dilation) and dilation group (physiological saline injection and dilation). The patients' characteristics, locations of lesions, number of previous dilations, esophageal diameters after dilation, grades of dysphagia before and after the procedure and dysphagia-free period during the follow-up period were recorded. RESULTS Altogether 74 patients including 25 in the mitomycin C group, 25 in the dexamethasone group and 24 in the dilation group were enrolled. The diameter of the esophagus before the procedure was 3.32 ± 0.90 mm, 3.92 ± 1.55 mm and 3.70 ± 1.30 mm, respectively, while that was increased to 12.77 ± 1.62 mm, 12.14 ± 1.28 mm and 12.73 ± 1.42 mm after endoscopic dilation in the mitomycin C, dexamethasone and conventional dilation groups. The dysphagia-free period was 4.88 ± 1.66 months in the mitomycin C group, 4.02 ± 1.77 months in the dexamethasone group and 2.41 ± 1.26 months in the dilation group (P < 0.05). CONCLUSION Intramuscular injection of mitomycin C or dexamethasone may prolong the dysphagia-free period and decrease the frequency of repeat dilations compared with conventional endoscopic dilations in patients with benign esophageal strictures.

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.
