Abstract
OBJECTIVES Caustic ingestion can have a complicated clinical course. Corticosteroids are widely used but there is uncertainty about its role in preventing esophageal stricture formation following caustic ingestion. This systematic review and meta-analysis assessed the available clinical evidence regarding the efficacy and safety of corticosteroids for preventing esophageal strictures following caustic injury. METHODS We assessed randomized controlled trials (RCTs) that compared corticosteroids versus no corticosteroids in the prevention of esophageal stricture formation following caustic ingestion. We searched the following databases from inception to March 2017: PubMed, Embase, and the Cochrane Central Register of Controlled Trials. Two reviewers retrieved eligible articles, assessed risk of bias, and performed data extraction. The main outcome measure was the prevention of esophageal stricture formation. RESULTS The search identified 763 citations. Three RCTs involving 244 participants met the inclusion criteria. There was no benefit of corticosteroids in the prevention of esophageal strictures following the ingestion of caustic materials (risk ratio [RR] = 0.63, 95% CI = 0.29-1.37). CONCLUSIONS The available evidence does not support the use of corticosteroids for the prevention of esophageal strictures following caustic ingestion. The overall quality of the evidence is limited because of methodological weaknesses and small sample sizes in the primary studies.

Abstract
The aim of this study was to determine the necessity of endoscopy in cases in which a corrosive substance was ingested and to find a practical way to avoid unnecessary endoscopies for similar cases in the future. The clinical records of 458 hospitalized cases with clinical histories of corrosive substance ingestion between January 2007 and December 2013 were retrospectively reviewed. The demographics of the cases, the ingested substances, and the rigid endoscopy findings were evaluated. The three most commonly ingested corrosive agents were household bleach (22.9%), household degreaser (15.9%), and drain cleaner (13.1%). Rigid esophagoscopy was performed in 367 of the 458 cases. Corrosive agents were grouped according to their purpose of household use; eight groups were created. The degree of corrosive injury observed in the different groups was compared with the degree of injury caused by household bleach. Among the corrosive agent groups, dishwashing machine products (Gr.1), laundry products (Gr.2), liquid cleaners (Gr.3), and household bleach (Gr.4) did not cause high-grade injuries. The resulting injuries and esophagoscopy results among the above groups, whether symptomatic or not, did not differ from one another. Corrosive agents such as drain cleaner (Gr.6), household degreaser (Gr.7), and several other acidic products (Gr.8) caused high-grade injuries in the esophagus; however, lime remover/HCl (Gr.5) did not. Thus, hospitalization and rigid endoscopy seem unnecessary to assess esophageal injury in most cases, if the ingested corrosive agent fits into group 1, 2, 3, or 4 and if the patient can be easily fed. Esophagoscopy is useful to shorten the hospitalization times in cases where strong corrosive agents were ingested, such as those in groups 5, 6, 7, and 8.

Abstract
Background: Corrosive esophageal injury causes serious clinical problems. We aimed to create a new experimental esophageal burn model using a single catheter without a surgical procedure. Materials and methods: We conducted the study with two groups of 12 male rats that fasted for 12 h before application. A modified Foley balloon catheter was inserted into the esophageal lumen. The control group was given 0.9% sodium chloride, while the experimental group was given 37.5% sodium hydroxide with the other part of the catheter. After 60s, esophagus was washed with distilled water. The killed rats were examined using histopathological methods after 28 days. Results: In comparison with the histopathological changes experienced by the study groups, the control groups were observed to have no pathological changes. Basal cell degeneration, dermal edema, and a slight increase in the keratin layer and collagen density of submucosa due to stenosis were all observed in the group subjected to esophageal corrosion. Conclusion: A new burn model can thus, we believe, be created without the involvement of invasive laparoscopic surgery and general anesthesia. The burn in our experiment was formed in both the distal and proximal esophagus, as in other models; it can also be formed optionally in the entire esophagus.

Abstract
INTRODUCTION An experimental study was conducted to investigate the effects of erythropoietin on the acute phase of esophageal burn damage induced by sodium hydroxide. MATERIALS AND METHODS A standard esophageal alkaline burn was produced by the application of 10% sodium hydroxide to the distal esophagus in an in vivo rat model. Fifty-six female rats were allocated into three groups: Group BC (baseline control, n = 8) rats were uninjured and untreated, Group PC (positive control, n = 24) rats were injured but untreated and Group EPO (erythropoietin-treated, n = 24) rats were injured and given subcutaneous erythropoietin (1,000 IU/kg per day), 15 min, 24, and 48 h after administration of the NaOH solution. Six animals from Group PC and six from Group EPO were killed at 4, 24, 48, and 72 h after application of NaOH to the esophagus. All of animals in Group BC were killed 4 h after exposure to 0.9% NaCl. Oxidative damage was assessed by measuring levels of malondialdehyde (MDA) and nitric oxide (NO), and activities of superoxide dismutase (SOD) and catalase (CAT) in homogenized samples of esophageal tissue. Histologic damage to esophageal tissue was scored by a single pathologist blind to groups. RESULTS MDA levels in the BC and EPO groups were significantly lower than those in the PC group (p < 0.05). CAT and SOD activities, and NO levels in the BC and EPO groups were significantly higher than in the PC group (p < 0.05). Esophageal tissue damage measured at 4, 24, 48, and 72 h after NaOH application was significantly less in the EPO group than in the PC group (p < 0.05). CONCLUSIONS When administered early after an esophageal burn induced by 10% sodium hydroxide in this rat model, erythropoietin significantly attenuated oxidative damage, as measured by biochemical markers and histologic scoring.

Abstract
OBJECTIVES This study was evaluated to investigate the efficacy of caffeic acid phenethyl ester (CAPE), which is a natural honeybee product exhibits a spectrum of biological activities including anti-microbial, anti-inflammatory, antioxidant and anti-tumoral actions, on the prevention of stricture development after esophageal caustic injuries in the rat. METHODS Thirty healthy male Wistar albino rats were utilized in this study. The rats were randomly allotted into one of three experimental groups: group A (sham) animals were uninjured. Caustic esophageal burn was created by applying 1 ml 37.5% NaOH to the distal esophagus. Group B rats were injured but untreated. Group C rats were injured and received CAPE (10 micromol/kg/day i.p. for 28 days). Efficacy of the treatment was assessed by measuring the esophageal transit time, stenosis index, histopathologic damage score and biochemically by determining tissue hydroxyproline content, lipid peroxidation and antioxidant enzyme activities. RESULTS The esophageal transit time, the stenosis index, histopathologic damage score and the hydroxyproline level were significantly increased in the untreated group compared with the sham and CAPE-treated groups. Treatment with CAPE decreased tissue hydroxyproline levels, histological damage, and the stenosis index, but except the esophageal transit time. Caustic esophageal burn also increased the lipid peroxidation and decreased the antioxidant enzyme activities in the untreated group. CAPE treatments decreased the elevated lipid peroxidation and also increased the reduced antioxidant enzyme activities. In corrosive esophageal burn group with no treatment, the most consistent findings were degenerative changes and increased in submucosal collagen content, and the luminal narrowing. CAPE treatment protected esophagus. Nevertheless, there was the slight increase in submucosal collagen. CONCLUSIONS It is concluded that CAPE has a preventive effect on the stricture development after esophageal caustic injuries in the rat.

Abstract
OBJECTIVE Stricture formation is a late complication of caustic esophageal burn, which is a common problem in childhood. For this reason, this experimental study was designed to observe the possible effect of nitric oxide on healing and fibrosis formation in caustic esophageal burns. MATERIALS AND METHODS The rats were divided into five groups. Group A (n=12) received sham burn and treatment with saline injection. Group B (n=34) received caustic burn. Rats in group C (n=31), were given water supplement with 10 g/L L-arginine that was started 24 h preoperatively and continued until postoperative day 4. In group D (n=21), S-methylisothiourea (SMT, specific inducible nitric oxide synthase (iNOS) inhibitor), was injected at a dose of 3 mg/kg i.p. at 30 min before caustic burn, and similar dose was reinjected immediately after caustic burn. SMT 6 mg/kg/day injections continued for 4 days long. In group E (n=22), Nomega-nitro-L-arginine (L-NNA, nonspecific nitric oxide synthase (NOS) inhibitor) was injected at a dose of 15 mg/kg i.p. at 30 min before caustic burn, and similar dose was reinjected immediately after caustic burn. L-NNA 30 mg/kg/day continues for 4 days. RESULTS Dead rates were significantly higher in group E than in groups A-D. The mean hydroxyproline levels in esophageal tissue were significantly lower in groups A and B than in group D. Histopathologically, tissue damage scores in the esophageal tissue were higher in group D than in groups A-C. CONCLUSIONS Inhibition of iNOS with SMT was impaired in wound healing due to caustic esophageal burn and provoked collagen accumulation at a later period. Those effects may due to inhibition of antioxidant, immunomodulatory and antifibrotic effects of NO.

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
Using a new class of intracellular 2nd messengers to prevent stricture formation after caustic ingestion, sphingosylphosphorylcholine (SPC) has a wide spectrum of activity in cell growth regulation and signal transduction. Caustic esophageal burns were created with 15% NaOH in an experimental rat model. Control group animals (n = 10) had esophageal burns with no treatment, whereas the SPC group (n = 10) had esophageal burns gavaged with SPC for 7 days. Efficacy of treatment was assessed in 28 days by contrast esophagograms, histopathologic evaluation, and biochemically by tissue hydroxyproline (OHP) content. Contrast esophagograms demonstrated that SPC significantly prevented stricture formation. Obvious collagen deposition was present in submucosa, muscularis mucosa, and muscular layers in the control group compared with the SPC group. The damage to the esophageal wall on histopathologic examination was significantly lower in the SPC group (p < 0.05). Tissue OHP contents were significantly lower in the SPC-treated group (3.0 +/- 0.1 microg/mg) compared with the control group (4.3 +/- 0.2 microg/mg) (p < 0.05). We conclude that SPC improves healing following caustic esophageal burns. Furthermore, SPC is effective in preventing caustic esophageal strictures. These effects of SPC occur through its proliferative and specifically its remodeling effects on wound healing.

Abstract
BACKGROUND/PURPOSE Caustic esophageal burn is a serious problem in pediatric surgery. Even though many clinical and experimental studies had been performed, the complication rate could not be reduced to a satisfying level. In this study, the authors evaluated the effects of hyperbaric oxygen (HBO) therapy in caustic esophageal burn in rats. METHODS Rats were divided into 4 groups, and caustic burn at the distal esophagus was created by applying 50% NaOH for 3 minutes in all groups. The first and third groups did not receive HBO therapy. HBO therapy was applied to the second group for 2 days and to the fourth group for 28 days. To evaluate the effects of short-term HBO therapy, the first 2 groups were compared for ulceration, inflammation, and submucosal vascular thrombosis after 2 days. The third and fourth groups were compared for the long-term effects of HBO therapy. Rats in these groups were killed after 28 days and compared for the collagen content, weight, and mortality rate. RESULTS In the second group, which received 2 days of HBO therapy, ulcer depth and vascular thrombosis were significantly lower than these in the first group (P =.022 and P =.020, respectively). The fourth group, which received 4 weeks of HBO therapy, had a significantly reduced mortality rate, weight loss, and collagen score and hydroxyproline level if compared with the third group (P =.035; P =.016; P =.028; and P =.033, respectively). CONCLUSIONS These results indicate that HBO therapy is useful in caustic esophageal burn both in short-term and long-term use.

Abstract
BACKGROUND/PURPOSE An experimental study was performed to modify the healing response in caustic esophageal burns to prevent stricture development. Two different agents with different modes of actions, caffeic acid phenethyl ester (CAPE) and epidermal growth factor (EGF), were studied. CAPE has antiinflammatory, immunomodulatory, antioxidant, and antimitotic properties. EGF has known properties in supporting wound healing and in protecting esophagus from injuries. METHODS The model described by Gehanno and its modification by Liu was used to create standard esophageal burns with 50% NaOH. The study was performed with 76 rats in 4 main groups (sham, CAPE, EGF, and control) and 2 subgroups in each for 5 and 28 days of observation. Efficacy of treatment was assessed in 28-day subgroups by measuring weight gain, contrast esophagograms on day 27, histologic evaluation by measuring stenosis index (wall thickness/lumen diameter), and collagen deposition, and biochemically by determining tissue hydroxy proline (OHP) content. RESULTS In the end of the study, increase rates of mean body weights of the animals in the 28-day subgroups were as follows: sham, 30%; CAPE, 23%; EGF, 22%; and control, 14%. Although all the animals in subgroups significantly gained weight, the mean weight gain was significantly low in controls when compared with sham, CAPE, and EGF groups (P <.05). Contrast esophagograms on day 27 showed no stenosis in the sham, mild stenosis in CAPE and EGF, and severe stenosis with proximal dilatation in controls. Stenosis indices of the subgroups were as follows: sham, 0.29; CAPE, 0.41; EGF, 0.41; control, 0.84. Index was significantly higher in controls (P <.05). Collagen accumulation scores in the esophageal wall were as follows: Sham, 0.0; CAPE, 0.87; EGF, 0.30; control, 2.70. Scores also were significantly higher in controls (P <.05). Tissue (OHP) levels were as follows (mg/g dry tissue): Sham, 1.48; CAPE, 1.53; EGF, 1.90; control, 4.01. Production of OHP was significantly higher in controls. CONCLUSIONS The results of the parameters in the study indicate that administration of CAPE and EGF has beneficial effects in the prevention of caustic esophageal strictures. Those effects of CAPE may occur through its antiinflammatory, immunomodulatory, and antioxidant properties, and EGF may occur through its induced proliferative properties on the esophagus.

Abstract
The records of 115 children hospitalized following caustic ingestion over an 18.5-year period from 1976 to 1994 were reviewed. The relationship between types of product ingested, signs and symptoms, degree of esophageal injury and complications was analyzed. All complications were the result of strong alkali ingestion (sensitivity = 1.0). Among the 102 incident patients, 36.8% of lye ingestions resulted in complications, whereas only 2.7% (one) of automatic dishwasher detergent (ADD) ingestions caused any complications (p < 0.01). Endoscopy 6 h to 4 days after injury was accurate in predicting or identifying complications in all types of strong alkali ingestions. In lye ingestions, endoscopy was not superior to the test, "one or more signs or symptoms" in predicting complications (predictivity = 1.0). Endoscopy is recommended to establish or confirm a prognosis, or to identify acute respiratory complications, in symptomatic ingestions of lye or ammonia water, in children with respiratory symptoms, and in rare cases of severe symptoms following ADD or strong acid ingestion. It is suggested that children who are non-symptomatic following unintentional ingestions are not at risk of complications and do not need endoscopic examination.

Abstract
The records of 86 adults admitted to hospital following caustic ingestion were reviewed. Eighteen patients (21%) developed complications; of these, six were fatal. Patients without symptoms or signs did not develop complications. Complications occurred only following lye ingestion, or intentional ingestion of hydrochloric acid or ammonia water. Of patients with such ingestion, and two signs or symptoms or more, 70% developed complications. Oesophagoscopy did not significantly improve the prediction of complications. There was a strong trend, however, for more severe complications with more severe submucosal, circumferential oesophageal injuries (P = 0.003). The study suggests that only adults with symptoms or signs following strong alkali or strong acid ingestion are at risk of complications. In adults who are symptomatic following ingestion of strong acid or alkali, oesophagoscopy is important to identify the potentially fatal transmural injuries.
