The upper endoscopy or panendoscopy is an useful procedure for the examination of the interior of the esophagus, stomach, and duodenus.
Through the use of endoscopic procedures it is possible to diagnose the presence of polyps (growth of tissue in the form of a wart) in the esophagus or the stomach that could be precursor for cancer. Their removal is possible with a polypectomy, an endoscopic procedure that causes no pain or discomfort, avoiding the need for open surgery.
With the advent of the endoscopy it is possible to identify and remove foreign objects swallowed accidentally, as in the case of coins, pins, needles, thorns, bone fragments, watch batteries, among other things. It is important to note that batteries must be removed as soon as possible as their ingestion could result in a perforated stomach or esophagus, and depending on the place it is found it could result in lethal intoxication.
Patients who are unable to ingest or swallow food can have a tube placed with the aid of endoscopy to provide food directly to the stomach for the necessary time. This is an excellent alternative to surgical placement of the feeding tube that requires admission to hospital, use of the operating room, and general anesthesia.
Diagnosis of stomach or esophageal cancer at initial stages. An upper endoscopy with high definition and digital chromoendoscopic technologies allows us to identify cancerous lesions in early stages. These lesions can be removed endoscopically to stop their development into more advanced stages of cancer, avoiding the need for open surgery and lengthy recovery.
