Upper Gastrointestinal Endoscopy Counsel

Upper endoscopy is the procedure of choice to detect the severity of mucosal injury, information esophageal healing, and rule out Barrett's esophagus, esophageal cancer, and other esophageal or GI causes of reflux-type symptoms. Endoscopy (with biopsy) of the esophageal mucosa is indicated for patients who are unresponsive or intractable to potent antisecretory drug therapy or in those with dysphagia, odynophagia, or GI bleeding, to regulation out esophageal cancer; in patients with long-standing GERD, to rule elsewhere Barrett's esophagus; and in patients with atypical symptoms, when the response to empirical therapy is difficult to evaluate. Esophageal strictures can be detected by endoscopy in most cases, but certain strictures (e.g., esophageal webs) are best evaluated by barium swallow. It is valuable to recognize that a normal endoscopy does not law out symptomatic GERD and the presence of esophagitis does not always demonstrate that esophagitis is the cause of the patient's symptoms. Additional tests, such as 24-h esophageal pH monitoring, may be essential to correlate symptoms with the presence of acid in the esophagus, help in the diagnosis, and advice manage therapy.
Barrett's esophagus is a histologic diagnosis that, at the interval of endoscopy, is recognized by the displacement of the squamocolumnar junction or Z line (the boundary between the pale pink squamous esophageal mucosa and the deep coral columnar gastric mucosa) into the lumen of the esophagus. Barrett's oesophagus is too suspected when deep-red patches of columnar epithelium exist within the lighter squamous mucosa. Most cases of dysplasia, however, come off in the absence of an endoscopically visible lesion. If Barrett's esophagus is confirmed, periodic endoscopic suveillance with biopsy is indicated to recorder for the manner of dysplasia. The optimal frequency of endoscopic surveillance in patients WithOUt dysplasia has yet to be driven however recommendations scope from every 18 to 24 months to every 5 years. Provided dysplasia is ad hoc more energetic monitoring (e.g., every 6 to 12 months) or esophageal resection is needed, depending On a symbol of factors induding the age of the patient and the grade (low versus high) of dysplasia.
Radiographic Studies
Barium radiography rarely shows free GER of the contrast agent and thus is less pleasant for the diagnosis of GERD. Although a double-contrast barium esophagogram may be used to principle absent esophageal ulcers, with certain types of esophageal strictures (e.g., esophageal webs), hiatal hernia, or extrinsic compression, radiography fails to detect most cases of esophagitis or Barrett's esophagus so endoscopy is preferred. A popular radiograph rarely predudes the need for subsequent endoscopy, whereas an initial endoscopic examination infrequently requires additional testing before proceeding with treatment.
