Cooling or Warming the Esophagus to Reduce Esophageal Injury During Left Atrial Ablation in the Treatment of Atrial Fibrillation

Chemical burns of the upper gastrointestinal tract
Abstract:
Burns of the upper gastrointestinal tract, caused by acids, alkalis, drugs or heat may lead to stenoses, some of them severe, to perforations, to inanition and to the patient's death. The type of damage differs among the various groups of noxious agents. First aid at home is almost non existent. On admission every effort must be made to identify the ingested material. Parenteral fluids and antibiotics are used and in some patients nutritional support will be required. The extent of the damage must be evaluated endoscopically. Strictures, caused by intramuscular collagen formation, could possibly be prevented by steroid therapy. If stenoses occur, these must be cautiously dilated. A late complication of oesophageal burns is carcinoma. There appears to be a relation between this grave complication and the use of very hot beverages in certain countries where oesophageal cancer is common. Upper gastrointestinal burns are similar to skin burns, however, their dangers may be greater as they occur in a pipe-like structure and very close to vital viscera.

Burn Injuries
The damage results in the death of skin cells, which can lead to a massive loss of fluid. Dehydration, electrolyte imbalance, and renal and circulatory failure follow, which can be fatal. Burn patients are treated with intravenous fluids to offset...

Gastritis-I: Introduction and Types
Acute gastritis presents as a sudden inflammation triggered by various stressors to the stomach lining, such as exposure to corrosive agents, local irritants like aspirin and other NSAIDs, alcohol consumption, radiation therapy, physical trauma, severe burns, sepsis,...
Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
