Acetic Acid produces reversible intracellular denaturalization of cytoplasmic proteins. When sprayed at distal esophagus, at squamous columnar junction, by using a high-resolution endoscopy video, it allows the detection of non-visible areas of the columnar epithelium and highlights the squamous columnar junction. Patients: After letting them know, subjects who had been prescribed an upper digestive endoscopy were included. Methods: The equipment used to perform the endoscopic procedure was Fujinon HR250. 5-10cc 5% acetic acid was instilled with a polyethylene catheter through the biopsia channel in the distal 5cm of the esophagus further washed away by water at room temperature. Results: Whitening of the acetic-acid-irrigated zone was observed in all cases. Almost immediately the squamous columnar junction demarcation was identified. The proximal gastric portion and the esophagus columnar epithelium were reddened with the water washing, allowing a highlighted and enhanced pit pattern to be observed. No adverse effects showed during or after the procedure. Conclusion: Acetic acid is an easy, rapid, safe, and inexpensive that, in the esophagus, highlights the squamous columnar junction, improves the detection and identification of the columnar epithelium and of its pit pattern as well.
