Abstract
Esophageal stenosis can cause vomiting or dysphagia in children and is commonly treated with esophageal balloon dilation. However, surgery may be required if the stenosis does not respond to dilation. Although esophageal actinomycosis can cause severe esophageal strictures and be refractory to balloon dilation, it has been reported to respond effectively to antimicrobial therapy in adults. However, the course of the disease and appropriate treatment strategies in children are not well understood. We present a case of a previously healthy 2-year-old boy diagnosed with esophageal stenosis because of actinomycosis. The patient was treated with intravenous penicillin G, followed by oral amoxicillin for 8 weeks and 6 months, respectively. After completion of the antimicrobial treatment, the patient showed improvement in symptoms and endoscopic findings. At the 1-year follow-up, the patient showed consistent weight gain and normal growth without further intervention. This case highlights the importance of considering esophageal actinomycosis as a potential cause of esophageal stenosis in children and the potential effectiveness of antimicrobial therapy in avoiding surgical intervention.

Abstract
Localized photodynamic therapy (PDT) uses a polymeric-photosensitizer (PS)-embedded, covered self-expandable metallic stent (SEMS). PDT is minimally invasive and a noteworthy potential alternative for treating esophageal strictures, where surgery is not a viable option. However, preclinical evidence is insufficient, and optimized irradiation energy dose ranges for localized PDT are unclear. Herein, we validated the irradiation energy doses of the SEMS (embedded in a PS using chlorin e6 [Ce6] and covered in silicone) and PDT-induced tissue changes in a rat esophagus. Cytotoxicity and phototoxicity in the Ce6-embedded SEMS piece with laser irradiation were significantly higher than that of the silicone-covered SEMS with or without laser and the Ce6-embedded silicone-covered SEMS without laser groups (all p < 0.001). Moreover, surface morphology, atomic changes, and homogeneous coverage of the Ce6-embedded silicone-covered membrane were confirmed. The ablation range of the porcine liver was proportionally increased with the irradiation dose (all p < 0.001). The ablation region was identified at different irradiation energy doses of 50, 100, 200, and 400 J/cm2. The in vivo study in the rat esophagus comprised a control group and 100, 200, and 400 J/cm2 energy-dose groups. Finally, histology and immunohistochemistry (TUNEL and Ki67) confirmed that the optimized Ce6-embedded silicone-covered SEMS with selected irradiation energy doses (200 and 400 J/cm2) effectively damaged the esophageal tissue without ductal perforation. The polymeric PS-embedded silicone-covered SEMS can be easily placed via a minimally invasive approach and represents a promising new approach for the palliative treatment of malignant esophageal strictures.

Abstract
Refractor esophageal stenosis after endoscopic submucosal dissection of early esophageal carcinoma is a difficult clinical problem. To verify the effect of endoscopic radial incision combined local triamcinolone injection to treat refractory esophageal stenosis, we retrospectively analyzed 7 patients diagnosed with refractory esophageal stricture after endoscopic mucosal dissection of early esophageal cancer in this study, of whom 4 male and 3 female patients, aged 50-76 years, with the mean age of 63 years. We performed the endoscopic radial incision in the thickness point of the scar stricture and injected the triamcinolone locally. The results showed it was safe and effective. The follow-up showed no esophageal stenosis occured and no adverse reaction such as hemorrhage, perforation, tumor-recurrence and triamcinolone-allergy occured.

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
BACKGROUND The prevalence of esophageal stenosis caused by immune checkpoint inhibitors in the context of induced immune mucositis and esophagitis is extremely rare. CASE PRESENTATION We report the case of a patient with stage IV pulmonary adenocarcinoma treated for 6 months with nivolumab who developed bilateral sterile conjunctivitis followed by oropharyngeal mucositis and esophagitis complicated by a severe esophageal stenosis. The laryngeal margin and hypopharyngeal mucosa appeared highly inflammatory with fibrinous deposits. Esophagogastroduodenoscopy revealed mucositis with a scar-like structure immediately below the upper esophageal sphincter with nonulcerative mucosa and an inflammatory aspect of the entire esophagus. No involvement of the stomach was observed. Oropharynx biopsies displayed marked lymphocytic T cell-infiltration with several foci of monocellular necrosis in the squamous epithelium. No morphologic evidence of adenocarcinoma and no signs of mycotic, bacterial or viral infection were noted. A blood sample revealed a discrete increase in the erythrocyte sedimentation rate (ESR) with no eosinophilia or leukocytosis. Liver and kidney function panel tests were normal. A thoracoabdominal CT scan reported no evidence of disease recurrence. Despite multiple boluses of methylprednisolone and high doses of prednisone continued for several months, the patient experienced very rapid symptomatological reappearance during three steroid tapering attempts and aggravation of his esophageal stenosis to an aphagic stage, requiring a nasogastric tube. This long course of high-dose corticosteroid treatment was complicated with osteoporosis-induced fractures with several spontaneous compressions of thoracolumbar vertebrae requiring an enlarged T10 to L5 cementoplasty. Anti-IL-6 blockade therapy with tocilizumab resulted in excellent clinical response, allowing the total resolution of the immune-related adverse events (irAEs) and leading to successful steroid tapering. CONCLUSIONS Herein, we describe the first case of a patient who developed autoimmune mucositis and esophagitis complicated by a severe refractory esophageal stenosis induced during treatment by nivolumab, which completely resolved after personalized treatment with tocilizumab, suggesting a role of IL-6 blockade in the management of severe steroid refractory esophageal stenosis and more broadly in refractory immune-related adverse events.

Abstract
BACKGROUND & AIMS Benign anastomotic strictures are often difficult to treat. We assessed the efficacy of adding corticosteroid injections to endoscopic dilation therapy with Savary bougienage. METHODS In a multicenter, double-blind trial, 60 patients (mean age, 63 ± 9 years; 78% male) with an untreated cervical anastomotic stricture after esophagectomy with gastric tube reconstruction and dysphagia for at least solid food were randomly assigned to groups given 4 quadrant injections of 0.5 mL triamcinolone (40 mg/mL, n = 29) or saline (controls, n = 31) into the stricture, followed by Savary dilation to 16 mm. Dysphagia, complications, and quality of life were assessed after 1 and 2 weeks and 1, 3, and 6 months. The primary end point was a dysphagia-free period of 6 months. RESULTS In the corticosteroid group, 45% of the patients remained dysphagia-free for 6 months, compared with 36% of controls (relative risk, 1.26; 95% confidence interval, 0.68-2.36; P = .46). Median time to repeat dilation was 108 days (range, 15-180 days) in the corticosteroid group vs 42 days (range, 17-180 days) for controls (P = .11). A median number of 2 dilations (range, 1-7) was performed in the corticosteroid group vs 3 dilations (range, 1-9) in controls (relative risk, 0.76; 95% confidence interval, 0.42-1.38; P = .36). Two major intervention-related complications occurred, 1 submucosal laceration in the corticosteroid group and 1 hemorrhage in the control group. Four patients in the corticosteroid group, but none of the controls, developed Candida esophagitis (P = .03). CONCLUSIONS Corticosteroid injections do not provide a statistically significant decrease in frequency of repeat dilations or prolongation of the dysphagia-free period in patients with benign anastomotic esophagogastric strictures. Dutch Trial Registration Number 2236.

Abstract
Biodegradable polymer stent with shape memory effect is expected to be developed in the treatment of esophageal stenosis, most likely due to traditional stents having such shortages as considerable rigidity and nondegradation. A tubular stent with the inner and outer diameters of 28 and 30 mm was manufactured from biodegradable poly(ε-caprolactone-co-DL-lactide) (PCLA) copolymer consisting of ε-caprolactone and DL-lactide at a weight ratio of 10/90. A series of tests were accomplished to investigate its properties including shape memory effects (SMEs), compression property and influence of in vitro degradation of polymer matrix on its shape recovery and dilation force. Significantly, an implantation of the stent into a dog model was performed to evaluate its function for the treatment of esophageal stenosis. The deformed stent needs about 36 s to recover its initial shape in vitro in 37°C warm water. The primary animal experiment in vivo has revealed that the implanted deformed stent could be triggered by body temperature and expectedly returned to a nearly-round shape to support esophageal wall. Therefore, the biodegradable intelligent polymer stent may be great potential to displace the conventional metallic stents for the esophageal stenosis therapy.

Abstract
We report a case of 50-year-old man with refractory anastomotic stricture after esophagectomy, which was successfully treated with endoscopic triamcinolone injection therapy. He received a curative operation for advanced thoratic esophageal carcinoma (Mt, Type 3, cT3, cN1, MO, Stage III). Anastomotic leakage was occurred as post-operative adverse event, which recovered conservatively, and subsequently resulted in refractory anastomotic stricture. He had a recurrence of dysphagia despite of repeated bougienage and endoscopic balloon dilatation. Four years later, he received an intralesional triamcinolone injection in anastomotic stricture every four weeks. According to the 5 courses of treatment, anastomotic stricture was cured and there was no recurrence confirmed. Intralesional triamcinolone injection may be one of the promising options for the treatment of refractory anastomotic stricture after esophagectomy.

Abstract
An experimental study was conducted to investigate the effects of allopurinol, which inhibits the enzyme xanthine oxidase, on oxidative stress and on the prevention of stricture development after esophageal caustic injuries in rat. A randomized controlled study was conducted and 60 Wistar albino rats were divided into 6 equal groups, three groups for the acute phase and 3 groups for the chronic phase. Caustic esophageal burn was created by application of 37.5% NaOH to the distal esophagus. Allopurinol was administered at 40 mg/kg daily. Efficacy of the treatment for the acute phase was assessed by measuring tissue malondialdehyde (MDA), nitric oxide (NO) and glutathione (GSH) at the 3rd day; and for the chronic phase by determining tissue hydroxyproline content and histopathologic damage score at the 28th day. We found an increase in XO, MDA and GSH levels and a decrease in NO levels in the acute phase. Allopurinol reinstated the increase in XO significantly, while MDA, GSH and NO levels were reinstated insignificantly. There was no significant difference in means of tissue hydroxyproline content. Histopathologic damage scores were significantly lower in the allopurinol treated group. This study, which is to our knowledge, the first in the literature investigating the influence of allopurinol on caustic esophageal burn, reveals that allopurinol effects MDA, GSH and NO levels insignificantly in the acute phase of caustic esophageal burn and decreases fibrosis significantly in the chronic phase.

Abstract
We present 2 cases of successful treatment of recurrent anastomotic strictures using a topical application of mitomycin C. In the first case, a 4-year-old boy had a cervical cyst excised, which appeared to be an ectopic gastric mucosa. He consequently presented severe stenosis at the origin of the cervical esophagus that needed repeated balloon dilatations. The second case is about a 12-year-old girl who presented a traumatic complete rupture of the right mainstem bronchus managed by primary repair, with subsequent anastomotic stricture. Both patients were successfully managed with topical application of mitomycin C (1 mg/mL), and needed no more dilatations.

Abstract
AIM The late toxicities due to multimodal therapy of advanced head and neck cancers were analysed. The impact of cytoprotection with amifostine is the specific objective of this report. PATIENTS AND METHODS A total of 851 patients (717 men, 134 women) with head and neck cancer were included in this prospective study. Of these patients, 519/851 had received amifostine before radio(chemo)therapy, while 332 control patients had not received any kind of cytoprotection before irradiation. Primary radiochemotherapy was performed in 282 patients and adjuvant radiation was administered in 569. The follow-up examination was carried out at our outpatient department 21.4 months (median, range 2.3 to 149 months) after the primary therapy. RESULTS Late xerostomia was seen in 765/851 patients (89.9%). Altered taste was reported by 284/851 (33.5%). These symptoms were reduced significantly by amifostine. No influence was seen on interstitial lymph edema (48.4%), or stenosis of the cervical esophagus (20.4%). Secondary symptoms such as dysphagia (78.8%) also had a trend for reduction. CONCLUSION The administration of amifostine offers an opportunity to reduce selected long-term toxicities for survivors of head and neck cancer.

Abstract
An orally disintegrating tablet formulation of olanzapine (ODT olanzapine) is designed to dissolve rapidly upon contact with saliva. We describe a manic patient who has an esophageal stricture and chronic pharyngitis, two conditions that impede the swallowing of medications. She was successfully treated for her mania with this orally disintegrating formulation. This case report shows that ODT olanzapine may be useful in the psychiatric management of manic and other patients for whom olanzapine is appropriate, and who have an underlying medical condition that impedes swallowing oral medications.

Abstract
BACKGROUND Benign oesophageal strictures may occur as a complication of caustic ingestion or severe gastro-oesophageal reflux or as a sequela of oesophageal surgery and other fibrosing conditions. The traditional initial treatment of oesophageal strictures is intraluminal dilation; however, even if frequent, this occasionally may not provide adequate oesophageal lumen capacity or give significant symptom-free intervals, and restricturing after dilation is difficult and challenging. Topical postdilation application of an antifibrotic agent, mitomycin-C, in the treatment of an oesophageal stricture has been described. PATIENTS AND METHODS Eight centres participated, with a total of 16 patients (4 girls), median age 48 (range 0-276) months. The causes of stricture were as follows: caustic (10), post-trachea-oesophageal fistula repair (2), peptic (2), Crohn disease (1), and dystrophic epidermolysis bullosa (1). The median (range) length and diameter of the strictures were as follows: 22 mm (8-50 mm) and 1.5 mm (1-6 mm). Of the 16 patients, 15 had undergone repeated dilations varying from 3 to more than 1000 (daily self-bouginage) before mitomycin-C, and the median interval between dilations was 4 weeks. Mitomycin-C 0.1 mg/mL was applied after dilation for a median time of 3.5 minutes and a median of 3 (1-12) times. RESULTS Major success, both endoscopic and clinical improvement or cure, occurred in 10 of 16 patients. In 3 of 16 patients the interval period between dilations increased dramatically. Failure of therapy was considered in 3 of 16. All of the patients remained symptom free for a follow-up time of as long as 5 years. CONCLUSIONS Postdilation application of topical mitomycin-C resulted in major success in 62.5% of patients and partial success in 19%, and it may be a useful strategy in oesophageal strictures of differing causes that are refractory to repeated perendoscopic dilation.

Abstract
Accidental caustic ingestion is a common problem in young children at the age of 1 to 4 years. In cases of circular injuries of the oesophagus subsequent strictures can arise. Endoscopic balloon dilatation is the commonly used intervention but does not always lead to permanent improvement. We report the successful use of mitomycin C in a young boy in whom we could achieve ongoing relief of dysphagia after the unsuccessful long-term use of frequent endoscopic dilatations.

Abstract
There is a great deal of variation in individual management of non-sharp oesophageal food bolus obstruction in the United Kingdom. An e-mail survey of consultants and specialist registrars in ENT was carried out to establish current UK practice. A review of the published literature was under-taken to establish whether current practice is evidence based. The majority of practitioners (95%) do not proceed immediately to rigid oesophagoscopy but use antispasmodic drugs (83%), most commonly hyoscine butylbromide (Buscopan) and diazepam, to try to induce spontaneous passage of the obstruction. There is currently no evidence in the published literature to support the use of these drugs. The use of Buscopan seems to have been encouraged by a misquoted reference in a prominent ENT textbook. Better evidence is needed to establish the best form of treatment for this relatively common problem.

Abstract
INTRODUCTION Esophageal stenosis, due to its important implications on the patients' quality of life, poses a serious problem, often difficult to resolve, that requires therapeutical solutions that could irreversibly affect vital conditions and quality of life of those affected. For this reason our group has tried over the last thirty years to employ conservative solutions in the damaged aesophagus, showing that a complete cure is possible in most cases although the way to achieve this can be dramatically long. MATERIAL AND METHODS We present our experience employing topical Mitomicyn C over the last year and a half in eight patients, six of them affected with caustic stenosis and two with secuelae of esophageal atresia, highlighting the three cases that received at least five applications of the product. We describe the method employed that consists in the spraying of the correct dose using a flexible fibroscope on the dilated area, loading the dose in the container of the cleaning water of the fibroscope, employing a system that permits only to apply the exact quantity necessary of the product. The application time is five minutes and the dose is 0.4 mg/ml applying 5ml or 10 ml according to the patient's weight ( under 12 kg = 2.5 ml and over 25 kg=5 ml). Upon completion of the application, a washing of the product is performed using the same fibroscope. RESULTS From the eight cases in which it was applied, we analysed the three that received at least five doses. These were two boys of seven and eight years and a 25 year-old woman. In the children the dilatations interval has passed from 4-5 weeks to 8-11 respectively. The woman has passed from 12 to15 weeks. The children have been in the dilatation program more than 3 years and the woman more than 18. CONCLUSIONS Although the time period that we have been applying Mitomicyn C is still short, the symptom-free interval after dilatations is proving to be highly promising. This fact is highlighted in those patients included in the dilatation program recently. We have not seen any adverse side effect from the application of the product.

Abstract
Intragastric pH-metry and esophagogastroduodenoscopy has been performed in 64 patients with chemical burn of the esophagus. It has been revealed that 51.6% patients had hyperacidity, 25% - normacidity, and 23.4% - hypoacidity. Gastroesophageal reflux has been diagnosed in 50% patients according to pH-metry examination and in 80-100% patients according to esophagogastroduodenoscopy, duodenogastric reflux - in 25 and 34.4% cases, respectively. A direct correlation exists between gastroesophageal reflux and basal gastric acidity, severity of chemical burn of the esophagus. It is concluded that antisecretory therapy is mandatory in complex treatment of patients with chemical burn of the esophagus.

Abstract
We experienced one case with locally advanced esophageal cancer that he gained a good result by the multidisciplinary treatment including the operation followed by chemoradiation. The case was a 74-year old man with the middle thoracic esophageal cancer accompanied by severe malignant stricture. He couldn't take any water, and his general condition was poor, because he lost 5 kg of his weight. By the clinical examinations, his cancer had no apparent invasion to adjacent organ. So, we planned the operation gone ahead the chemoradiation for him to take water and meals earlier, and to prevent pneumonia. The esophagectomy through right-thoracotomy was done, and the pathological findings were type 3, well differentiated squamous cell carcinoma, pT3 N0, pStageII. Two months later after the operation, he took the chemoradiotherapy. 50 gray radiation therapy was done with chemotherapy including Cisplatin (10 mg/a time/week) and Tegafur (200 mg/day). About one and half a year after the operation, he sends good daily life with no recurrence. Recently, chemoradiotherapy is the first choice of the treatment for the locally advanced esophageal cancer. But in cases without apparent invasion to adjacent organ, it might be advisable that the operation goes ahead the chemoradiotherapy in the multidisciplinary treatment.

Abstract
OBJECTIVES To review the literature on the treatment of gastroesophageal reflux disease (GERD) with emphasis on pharmacological aspects. To identify particularities of pharmacological treatment of esophageal and extraesophageal manifestations of the disease. SOURCES Electronic search of the PubMed/MEDLINE and Cochrane Collaboration databases. Controlled and randomized studies published since 2000 and reviews representing consensus positions and directives published within the last 10 years were identified. SUMMARY OF THE FINDINGS The drugs currently available for the treatment of GERD do not act in the primary mechanism of the disease, i.e. transitory relaxation of the lower esophageal sphincter. Pharmacological treatment of GERD with symptoms or with esophageal injury is based on the suppression of acid secretion, particularly with proton pump inhibitors. When the hyperreactivity of the lower airways coexists with esophageal GERD symptoms, suppression of acid secretions should be of benefit in managing the respiratory disease in the presence of a causal relationship; however, this is not usual. When esophageal symptoms are not present, esophageal 24-hour pH study should be carried out prior to starting pharmacological treatment for GERD. Improvement of respiratory symptoms may be delayed with relation to esophageal symptoms. It is common for GERD to recur and pharmacological treatment should be repeated or continued indefinitely, depending on clinical presentation of the disease. CONCLUSIONS The strategies that have been proposed for the pharmacological treatment of GERD in children are primarily based on studies of case series or on studies with adults. There have been very few controlled and randomized studies in children. Undertaking a greater number of these studies might reinforce existing aspects or establish new aspects of management.

Abstract
We examined 110 patients treated conservatively for cicatricial esophageal stenosis including expansion on the string. The patients were divided into three groups: controls (n = 35), receiving adjuvant SUMS-1 (n = 38) and given adjuvant enterosgel (n = 37). According to electron microscopy, enterosorbents make esophageal mucosa denser by decreasing interstitial spaces as a result of microcirculatory improvement and reduction of edema. Enterosorbents elevate total protein and sugar in the blood.

Abstract
Although the incidence of caustic ingestion is declining, the management of caustic esophageal strictures remains a challenge. Mitomycin C (MMC) inhibits fibroblast proliferation and is effective in reducing scar in animal experiments. We report the case of a child with a distal esophageal stricture from lye ingestion managed with MMC. Despite repeated dilatations, at 1 year post injury, the stricture was 20% of esophageal diameter. Mitomycin C (4 microg/mL) was applied topically and circumferentially by endoscopy and repeated 4 months later. At 20 months follow-up, the child eats normally, and esophagram showed decreased stenosis (stricture was 50% of esophageal diameter). No complications were observed. Although controlled trials are required to confirm its efficacy, MMC should be considered as an adjunct in the management of caustic esophageal strictures in children.

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
BACKGROUND Caustic esophageal injuries lead to stricture formation. Although a number of agents have been tried experimentally to prevent strictures, few have gained clinical application. The purpose of this study was to investigate the effectiveness of Mitomycin C (MMC), which inhibits fibroblastic proliferation in preventing caustic esophageal strictures. MATERIAL AND METHODS Fifty-six rats were allocated into four groups. Caustic esophageal burns were created as described by Gehanno. Group A was instilled only with saline. Group B was injured and untreated. Groups C and D were injured and received topical MMC at 0.02 and 0.04% concentrations, respectively. At 28 days, stenosis index (SI), collagen deposition, and hydroxyproline content (HP) were determined in distal esophageal segments. Statistical analyses were done. RESULTS Mean SI in Group B was significantly higher than others (P < 0.05). Mean SI was statistically higher in Group C than A and D and similar between groups A and D. The greatest accumulation of collagen was found in Group B, followed by Group C, D, and A, respectively. Collagen deposition in Group D was statistically lower than Group B (P < 0.01) and similar to Group C. Mean HP in Group B was statistically higher than others (P < 0.05), significantly higher in Group C than Group D (P = 0.047), and similar between Groups A and D (P = 0.73). CONCLUSION MMC was effective in preventing strictures following experimental caustic esophageal injury, in a dose-dependent manner. We consider that it can gain clinical utilization with the establishment of effective mode, dose, and timing of therapy.

Abstract
PURPOSE The aim of this study was to investigate the efficacy of trimetazidine (TMZ), an antioxidant agent, on the prevention of stricture development after esophageal caustic injuries in rat. METHODS Thirty rats were divided into 3 equal groups. A standard esophageal caustic burn was produced by application of 37.5% NaOH for a period of 90 seconds followed by water rinse. Group A (sham) animals were uninjured. Group B rats were injured but untreated. Group C rats were injured and received TMZ (5 mg/kg/d) via intraperitoneal route. Efficacy of the treatment was assessed in 28 days by measuring stenosis index and histopathologic damage score and by determining tissue hydroxyproline content. RESULTS The stenosis index in the TMZ-treated group was significantly lower than the untreated group, similarly in the sham laparotomy group (stenosis index: 0.34 +/- 0.10, 0.94 +/- 0.21, 0.38 +/- 0.05, respectively; P < .05). The hydroxyproline level (microgram per milligram of wet tissue) was significantly lower in the TMZ-treated group compared with untreated group, similarly in the sham laparotomy group (1.06 +/- 0.14, 1.33 +/- 0.08, 0.68 +/- 0.15 microg/mg wet tissue, respectively; P < .05). In the untreated group, histopathologic damage score was significantly higher than TMZ-treated group (P < .05). CONCLUSIONS Trimetazidine reduces the degree of fibrosis and ameliorates histopathologic damage in experimental model of corrosive esophagitis in rats.

Abstract
OBJECTIVE Some benign esophageal strictures are highly resistant to bougie dilation. The aim of this study was to determine whether intralesional steroid injection had additional benefit to Savary-Gilliard's bougie dilation therapy (SGBD). METHODS Twenty-one patients were treated with a bougie dilator. The patients were randomized into control and study groups. There were 11 patients in the control group (7 males, 4 females; mean age 45.09 +/- 24.64 years) and 10 patients in the study group (4 males, 6 females; mean age 49.40 +/- 16.49 years). The patients in the control group underwent only SGBD, but patients in the study group received an additional intralesional steroid injection (8 mg triamcinolone acetate into each quadrant). The number of dilations was divided by the follow-up period (in months) to determine the periodic dilatation index. RESULTS There was no difference in age, sex, etiology, localization and recurrence of lesions, treatment outcome, complications and the number of dilations between the study and control groups. In the study group, the mean periodic dilatation index was 0.712 (range 0.097-2.75) and 0.289 (range 0-1) before and after injections, respectively (P = 0.03). Additionally, the mean number of dilations was 5.3 (range 2-11) and 1.6 (range 0-5) before and after injections, respectively (P = 0.03). The mean symptom-free interval was 24 +/- 12.75 months in the study group and 5.18 +/- 5.06 months in the control group (P < 0.001). The total periodic dilatation index was 0.193 +/- 0.123 in the study group, while it was 0.597 +/- 0.583 in the control group (P < 0.05). CONCLUSIONS It can be concluded that intralesional steroid injections increase efficacy of bougie dilation and decrease the requirement for repetition of bougie dilatation.

These children has second and third degree oesophageal burns and they were treated by systemic Methylprednisolone (1000mg/1, 73/m2 SC). We divided the 26 children in four groups according to the time we began the steroids (before or beyond the 24th hours of the accident and according the number of steroids's bolus (less or more than 21 bolus). We analysed the number and the treatment of stricture in each group. High doses of methyl prednisolone seem to decrease the risk of oesophageal stricture. We found no difference between the children treated before the 24th hours and those treated after the 24 hours and those treated with less than 21 bolus and those with more than 21 bolus.

Abstract
An experimental study was performed to investigate the efficacy of ketotifen, which is a mast cell stabilizer and histamine H(1)-receptor antagonist, on the prevention of stricture development after esophageal caustic injuries in the rat. Caustic esophageal burn was created by applying 37.5% NaOH to the distal esophagus. Forty rats were divided into four equal groups. Group A (sham) animals were uninjured. Group B rats were injured but untreated. Group C rats were injured and received ketotifen (1 mg/kg/day) via the oral route. Group D rats were injured and received ketotifen (1 mg/kg/day) via the intraperitoneal route. Efficacy of the treatment was assessed on day 28 by measuring the stenosis index and histopathologic damage score and biochemically by determining tissue hydroxyproline content. The stenosis index in group B (0.93+/-0.22) was significantly increased compared with group A (0.39+/-0.06, p <0.05), group C (0.42+/-0.09, p <0.05), and group D (0.35+/-0.07, p <0.05). The hydroxyproline level ( micro g/mg wet tissue) was significantly increased in group B (1.31+/-0.08, p <0.05) compared with group A (0.69+/-0.16, p <0.05), group C (1.06+/-0.16, p <0.05), and group D (0.95+/-0.12, p <0.05). In group B the histopathologic damage score was significantly higher than in groups C ( p<0.05) and D ( p<0.05). There was no significant difference between group C and group D in terms of all parameters evaluated. Treatment with ketotifen decreased tissue hydroxyproline levels, histological damage, and the stenosis index. We conclude that ketotifen has a preventive effect in the development of fibrosis in an experimental model of corrosive esophagitis in rats.

Abstract
AIM Little is known about the impact of widespread proton pump inhibitor use on the need for dilation of esophageal strictures. To determine the time trends for upper endoscopy and stricture dilation before and after the availability of proton pump inhibitors. METHODS The computerized databases of two large community hospitals were analyzed. Annual data on dilation procedures (by all methods) and upper endoscopy were obtained and analyzed in quartiles from 1986 to 2001 to determine if the relative or absolute need for dilation changed following the introduction of proton pump inhibitors in the United States. The number of prescriptions for acid suppressive agents (H2 receptor antagonists and proton pump inhibitors) for the corresponding time period was obtained from the IMS health database. RESULTS A total of 57,496 upper GI endoscopies and 2,868 esophageal dilations were performed. The proportion of patients undergoing esophageal dilation increased from 4% in 1986-1989 to 6% in 1990-1993 (p < 0.001), remained unchanged (5.8%) in the period from 1994 to 1997 but declined significantly to 3.9% (p < 0.001) in the next quartile (1998-2001). Absolute numbers of dilation procedures declined significantly in the last quartile (1998-2001) and the proton pump inhibitor prescriptions in the United States increased markedly from 1995 onward. CONCLUSIONS The need for stricture dilation peaked in 1994 and has declined thereafter, corresponding to an increase in the use of proton pump inhibitors. The widespread use of proton pump inhibitors has not, however, abolished the need for esophageal dilation.

Abstract
OBJECTIVE To determine triancinolone intralesional injections effects in association with esophageal dilations in corrosive stenosis cases, by means of a double-blind and randomized study. METHOD Fourteen adults patients (6 men and 8 women) with severe esophageal corrosive stenosis were randomized in two groups: Group A: treated by esophageal dilations and posterior triancinolone 10 mg/ml intralesional injection; Group B: treated by esophageal injections and posterior saline solution 0,9% injection (placebo). New applications were made based on the patient symptomatology. It had been analysed dilation frequency, obtained diameters and dysphagia before and after the research, for 12 months. RESULTS Eleven patients had ingested sodium hydroxide, two had ingested ammoniac and one had taken muriatic acid. There was no statistic difference (p > 0.05) in dilation frequency and dysphagia between the groups. However, an improvement in obtained diameter was observed in the corticosteroids group in comparison with control group (p < 0.05). By comparing groups before and after steroids, the final results were very favorable in group A CONCLUSION: Multiple intralesional injections of triancinolone hexacetonide 10 mg/ml in association with esophageal dilations increase obtained diameters in succeeding sessions.

Abstract
Since seven years, the 23-year-old woman suffered from severe dysphagia and cutaneous Candida-granulomas on the right side of the head, the nose and both hands. The therapy with different oral antimycotics was ineffective. Intravenously and orally administered high-dose fluconazole has induced healing of the mucocutaneous lesions. The esophageal stenosis, most likely caused by esophageal candidosis, was found as the origin of dysphagia. It was successfully treated by fluconazole and endoscopic dilatations.

Abstract
OBJECTIVES To assess the role of mitomycin C (MMC) in the management of pharyngoesophageal stricture after total laryngopharyngectomy and free flap reconstruction. STUDY DESIGN Five patients since 1998 underwent evaluation and treatment for pharyngoesophageal stricture after total laryngopharyngectomy and free flap reconstruction. The method of reconstruction included four tubed radial forearm free flaps and one jejunal free flap. All patients underwent barium swallow, computed tomography, and endoscopic examination and were proven to be free of recurrent disease. METHODS The patients were taken to the operating room. After dilation, the stenotic segment was exposed, and 1 mL of 0.4 mg/mL mitomycin-C was applied for 4 minutes using a cotton pledget. The patients were then followed clinically and with barium swallows for a minimum follow-up period of 18 months. RESULTS All five patients experienced improved swallowing ability. The need for further dilatations was either eliminated or lessened. All patients were happy with the treatment results. No complications occurred. CONCLUSIONS This small case series suggests that MMC is a safe and effective adjunctive treatment for pharyngoesophageal stricture after total laryngopharyngectomy and free flap reconstruction.

Abstract
INTRODUCTION Oesophageal surgery for reflux stricture is as challenging in adults as in the paediatric age group. Several management protocols, both medical and surgical, are currently proposed, such as bougienage, funduplication without dilatation, funduplication with pre- and postoperative dilatation, resection and interposition, and pharmacological therapy. However, reported results are not univocal. The aim of this work is to demonstrate that preoperative treatment with H2-antagonist combined with oesophageal dilatation and followed by anterior funduplication (Boix-Ochoa procedure with elongation of intraabdominal segment of the oesophagus) is a long-term, effective treatment for reflux stricture in children. It provides a tension free repair and an adequate protection to reflux, thus, preventing recurrences. MATERIALS AND METHODS In the last five years we observed oesophageal stenosis in 10 out of 49 children, operated for gastroesophageal reflux (mean age 62.9 months, range 12-156 months). All children underwent treatment with H2-antagonist (Ranitidine) and prokinetic agent (Cisapride), followed by oesophageal dilatations (mean 2.8, range 2-4 cycles) with Savary-Gillard dilators. An open anti-reflux procedure was performed (9 Boix-Ochoa and 1 Nissen) on children where a 9 mm endoscope passed easily through the oesophageal lumen. The pre and postoperative evaluation of all patients included symptoms assessment, esophagogram and endoscopy. RESULTS Results were satisfactory in 9 patients. Only one patient where a Nissen wrap was performed, incomplete relaxation was documented radiologically. The patient required several dilatations for residual dysphagia before reaching a symptom free status. All other patients had an average follow-up of 38 months (range, 5 months to 5 years) with relief from dysphagia and no recurrence of stricture. Radiological controls showed good oesophageal lumens, with normally positioned neocardias, opening regularly during barium passage with no sign of reflux. Multiple biopsies from endoscopic controls confirmed complete relief from oesophageal stricture but persistence of Barrett's mucosa. CONCLUSIONS Our treatment of choice for reflux stricture is preoperative pharmacological therapy followed by series of dilatation with Savary-Gillard dilators till oesophagus is adequately dilated. Antireflux surgery is mandatory when a stricture is observed. We prefer a Boix-Ochoa funduplication with extensive transhiatal mobilization of thoracic oesophagus. This results in a "tension free" fundoplication even when brachioesophagus is present. The procedure appears to be physiological for pediatric patients and in our hands was free from recurrences.

Abstract
BACKGROUND With the extensive use of COX-2 inhibitors to treat inflammatory and pain syndromes, gastrointestinal adverse effects are being increasingly observed. CASE REPORT An 87-year-old white man with chronic peptic esophageal stricture presented to us with dysphagia and odynophagia. The patient was taking Celecoxib for 5 months for trigeminal neuralgia. An upper endoscopy revealed severe desquamative esophagitis. Celecoxib was discontinued and the patient was started on esomeprazole. The patient's symptoms improved in 1 month. Three months later, EGD revealed complete healing of the esophageal mucosa. DISCUSSION Because recent studies have shown that COX-2 inhibitors are similar to NSAIDs with regards to absorption, in contrast to premarketing trials, extensive use of COX-2 inhibitors is likely to demonstrate gastrointestinal adverse effects similar to those caused by traditional NSAIDs. Our patient had severe esophagitis caused by Celecoxib and aggravated by reflux of achlorhydric gastric contents after dilatation of the stricture. SUMMARY We report for the first time severe esophagitis caused by the COX-2 inhibitor Celecoxib.

Abstract
BACKGROUND Eosinophilic gastroenteritis (EG) is an uncommon entity of which the pathogenesis is unclear. As no controlled treatment trials exist, treatment of EG remains largely empiric. Limited results have been achieved with oral cromolyn, ketotifen, and other antihistamines. Oral corticosteroids are effective, but long-term use is complicated by side effects including growth retardation, diabetes, and osteoporosis. OBJECTIVES We sought to determine whether treatment with montelukast would improve symptoms and decrease both peripheral blood and tissue eosinophilia (TE) in a patients with steroid-dependent EG for 20 years complicated by esophageal stricture. METHODS In an unblinded, n = 1 trial, we treated the patient for 5 months with montelukast (20 to 30 mg daily) while his baseline dose of prednisone (10 mg daily) was continued. Complete blood counts and symptoms were monitored weekly. Esophageal biopsies were obtained before and after 5 months of therapy with montelukast. After the posttreatment biopsy was obtained, montelukast was discontinued. Outcome measures included patient symptoms and peripheral and tissue eosinophil counts. RESULTS During treatment with montelukast, the mean peripheral blood eosinophil count fell from 5,064 cells/microL (average 28 determinations over 20 years; range 1,408 to 12,500 cells/microL) to 1,195 cells/microL (average 14 determinations over 16 weeks; range 556 to 2,193 cells/microL), a 76% reduction. The corresponding TE as calculated from esophageal biopsies was 31 eosinophils/high power field before and 70 eosinophils/high power field after treatment. The patient noted no appreciable improvement in esophageal symptoms. CONCLUSIONS Montelukast dramatically reduced peripheral blood eosinophilia, but did not affect TE or symptoms in this patient with severe, long-standing EG complicated by esophageal stricture.

Abstract
INTRODUCTION The cornerstone treatment for benign esophageal strictures is endoscopic dilation. There are reports suggesting that intralesional corticosteroid injection decreases the frequency of endoscopic dilation. METHODS Seventy-one patients (mean age 42.39 [17.52] years; range, 13-78 years) with benign esophageal strictures (corrosive 29, peptic 14, anastomotic 19, radiation-induced 9) were recruited for this study. All were being managed with a program of intermittent endoscopic dilation by using over-the-wire polyvinyl dilators. All patients were treated by intralesional injections of triamcinolone acetonide (40 mg/mL diluted 1:1 with saline solution) by using a 23-gauge, 5-mm long sclerotherapy needle in aliquots of 0.5 mL. At each session, 4 injections (4 quadrants) were made at the proximal margin of the stricture with another 4 injections into the strictured segment itself whenever possible. The intervals between dilations and frequency of dilations were calculated before and after triamcinolone injections. A periodic dilation index (defined as number of dilations required per month) before and after the triamcinolone injections was calculated. RESULTS The overall mean (SD) duration of treatment before intralesional injection was 10.9 (19.8) months (range, 1-120 months) and the mean number (SD) of esophageal dilations required was 9.67 (13.06) (range, 1-70). The mean number of sessions of intralesional injection was 1.4 (0.62). After initiation of intralesional injections mean follow-up was 8.1 (5.6) months (range 3-30 months) and the mean number of esophageal dilations was 3.8 (3.0) (range 0-16). The periodic dilation index decreased significantly from 1.24 (0.05) (range 0.13-3.16) before injection to 0.5 (0.33) (range, 0-2) after injection (p < 0.001). For each category of stricture, the periodic dilation index decreased significantly: corrosive, 1.24 (0.5) to 0.53 (0.34) (p < 0.001); peptic, 0.92 (0.44) to 0.42 (0.2) (p < 0.001); anastomotic, 1.24 (0.49) to 0.51 (0.4) (p < 0.001); and radiation-induced, 1.32 (0.6) to 0.6 (0.3) (p < 0.02). CONCLUSION Intralesional injections of triamcinolone augment the effects of dilation in patients with benign esophageal strictures.

Abstract
The authors describe 4 children with recurrent stenosis and persistent esophagitis after secondary repair of a long gap esophageal atresia. They underwent an esophageal reconstruction by elongation of the lesser gastric curvature according to Schärli at the age of 11 to 14 months. All had esophagitis grade III to IV (Savary-Miller classification), esophageal stenosis, and failure to thrive. Effective treatment of the esophagitis and prevention of stenosis consisted in high doses of omeprazole (1.9 to 2.5 mg/kg/d). After this treatment, the need for esophageal dilatation disappeared, and nutritional status normalized.

Abstract
Esophageal cancer usually presents at an advanced stage with dysphagia, and palliative therapy often is appropriate. Expandable metal stents are used for palliation because of their ease of insertion, but long-term complications remain common. Photodynamic therapy has been shown to be an effective ablative treatment for obstructing esophageal cancer, overall easier to use, and longer lasting than Nd:YAG laser ablation. Photodynamic therapy may be particularly useful in areas where stents may be problematic, such as in the upper esophagus, at the esophagogastric junction (where adenocarcinomas are increasing in frequency), and following radiation and chemotherapy.

Abstract
BACKGROUND Better control of gastric acid secretion with omeprazole appeared to decrease the need for dilatation of oesophageal strictures complicating gastro-oesophageal reflux disease in our hospital-based endoscopy service. AIM To investigate whether the perceived decrease in the need for oesophageal dilatation could be documented from endoscopy records, and, if confirmed, whether this could be related to the treatment used. PATIENTS AND METHODS Retrospective study of the records of 69 patients who had peptic oesophageal strictures dilated, followed by treatment with acid inhibition for at least 6 months. Mean duration of follow-up was 3.9 years during treatment with H2-receptor antagonists and 2.1 years while on omeprazole (258 and 78 patient-years, respectively). Re-dilatation rates were compared between those treated with H2-receptor antagonists or omeprazole. RESULTS There has been a significant decrease in dilatations performed for gastro-oesophageal reflux induced strictures (P<0.001), while dilatation rates for other indications remained constant. Treatment with omeprazole not only decreased the need for further dilatations, but also prolonged the mean time between any further dilatations to 26.3 months compared to 9.3 months for those on an H2-receptor antagonist (P<0.0001). CONCLUSIONS Following dilatation of peptic oesophageal strictures, treatment with omeprazole in place of an H2-blocker significantly decreases the need for repeat dilatation.
