Purpose: Caustic esophagitis is a serious clinical problem and many agents are currently tried out in many experimental models. The model of Gehanno is the most commonly used invasive model, which is required general anesthesia and laparotomy. We aimed to form a new pratic and non-invasive model.
Methods: Twenty rats were studied. The stomachs of the rats were reached through guidance catheter with ether anesthesia, Fogarty catheter was send in through, it was filled with pressure in the stomach. Then, Fogarty was pulled back and stomach entrance was closed. Control group was given; n = 10; 0.25 cc isotonic, injury group was given; n = 10; 0.25 cc, %40 NaOH and it was waited for 60 s. Their esophagi were examined after 28 days.
Results: In the histopathologic evaluation of the control group, no pathology was discovered. Sub-mucosal collagen increase, muscularis mucosa and tunica muscularis damage have all been detected in the injury group p < 0.005; p < 0.003; p < 0.005).
Conclusions: Corrosive esophagitis was formed without general anesthesia and laparotomy. Burn was formed in the total esophagus, unlike other models in which the burn is just formed at the below end. With our less invasive, more easily applied model; treatment agents can be given just as the corrosive esophagitis can be formed.

NiTi alloys are an important class of biomaterials with extensive clinical applications such as cardiovascular stents, orthodontic arch-wires, esophageal stents, orthopedic implants and more. However, the long-term implantation of NiTi alloys presents significant challenges due to their susceptibility to wear, corrosion and the excessive release of harmful nickel ions. These factors can severely compromise both the biocompatibility and the overall service life of the implants.

Introduction: The ingestion of foreign body (FB) is a common problem in paediatrics. Children are curious by nature and tend to explore environment by inserting objects into their mouths.
Aim: To update our epidemiological and clinical data and adapt clinical management in order to limit morbidity associated with this fairly frequent accidental pathology.

Esophageal stricture is the most common and disabling complication of esophageal injury caused by ingestion of corrosive substances. In our case, the patient developed esophageal stenosis due to ingestion of strong alkaline substances and underwent colon replacement surgery after repeated failed dilation treatments. After surgery, anastomotic stenosis and tracheocolonic fistula occurred successively, and the entire diagnosis and treatment cycle of this disease lasted for more than 20 years.

Background: Corrosive substance ingestion is rare but can cause severe injury, especially to the upper gastrointestinal tract, and can be a potentially fatal event. Various surgical procedures have been advocated for gastroesophageal reconstruction, but especially those using the right colon, when the ileocecal valve is preserved for gastric reconstruction, are briefly exposed in literature and have not been studied in humans by controlled studies. Using the right colon is believed to be beneficial because of the anti-reflux mechanism of the ileocecal valve.

Alkali caustic exposures can occur in the workplace with industrial chemicals, or in the home with common household products. These exposures, whether accidental or intentional, create risk for death or acute injury, such as airway compromise and esophageal or gastric perforation, as well as long-term complications such as stricture formation. Swift diagnosis and grading of these injuries will guide management options and are essential to reduce morbidity and mortality in these patients.
