In its most basic use, the endoscope is used to inspect the internal anatomy of the digestive tract. Often inspection alone is sufficient, but biopsy is a valuable adjunct to endoscopy. Small biopsies can be made with a pincer (biopsy forceps) which is passed through the scope and allows sampling of 1 to 3 mm pieces of tissue under direct ...
The most effective diagnostic tool for CMV is endoscopy with biopsy. Generally on inspection of the esophagus large punched out lesions are seen in the middle part of the esophagus. Further histological evaluation of the lesions demonstrates enlarged cells in the sub-epithelial layer with inclusions within the cell's nucleus and its cytoplasm ...

Endoscopy with biopsies of the esophagus has a 100% sensitivity and 96% specificity for diagnosing eosinophilic esophagitis. [8] Biopsy specimens from both the proximal/mid and distal esophagus should be obtained regardless of the gross appearance of the mucosa. Specimens should also be obtained from areas revealing endoscopic abnormalities.
Fundic gland polyposis is a medical syndrome where the fundus and the body of the stomach develop many fundic gland polyps.The condition has been described both in patients with familial adenomatous polyposis (FAP) and attenuated variants (AFAP), and in patients in whom it occurs sporadically.
Endomicroscopy is a technique for obtaining histology-like images from inside the human body in real-time, [1] [2] [3] a process known as ‘optical biopsy’. [ 4 ] [ 5 ] It generally refers to fluorescence confocal microscopy , although multi-photon microscopy and optical coherence tomography have also been adapted for endoscopic use.
The strip biopsy method for endoscopic mucosal resection of esophageal cancer is performed with a double-channel endoscope equipped with grasping forceps and snare. After marking the lesion border with an electric coagulator, saline is injected into the submucosa below the lesion to separate the lesion from the muscle layer and to force its ...
However, according to retrospective data, roughly one in seven patients with portal hypertensive gastropathy will develop bleeding (either acute or chronic) attributable to the gastropathy. [1] Patients with chronic bleeding will usually present with anemia. The diagnosis of portal hypertensive gastropathy is usually made on endoscopy.
