Following upper endoscopy, the balloon is inserted into the esophagus and the balloon is distended with a fluid with known properties (e.g. conductivity and volume). [1] Each electrode then measures impedance, and a single pressure sensor at the end of the device measures pressure within the balloon.
When a treatable lesion is identified on endoscopy (such as a bleeding vessel), an endoclip can be inserted through the channel of the endoscope until the sheathed clip is visible on the endoscopic image, and the handle for deployment handed to the nurse assistant. The clip is unsheathed by retraction at the handle, positioned, and "fired" by ...
APC involves the use of a jet of ionized argon gas directed through a probe passed through the endoscope. The probe is placed at some distance from the bleeding lesion, and argon gas is emitted, then ionized by a high-voltage discharge (approx 6 kV ). [ 1 ]
Enteroscopy is the procedure of using an endoscope for the direct visualization of the small bowel. Etymologically, the word could potentially refer to any bowel endoscopy (entero-+ -scopy), but idiomatically it is conventionally restricted to small bowel endoscopy, in distinction from colonoscopy, which is large bowel endoscopy.
Endoscopic ultrasound (EUS) or echo-endoscopy is a medical procedure in which endoscopy (insertion of a probe into a hollow organ) is combined with ultrasound to obtain images of the internal organs in the chest, abdomen and colon. It can be used to visualize the walls of these organs, or to look at adjacent structures.
Also, in cystoscopy, which is the examination of the urinary bladder with an endoscope, narrow-band imaging is useful in differentiating between benign and malignant cells. [6] Alternative methods to improve visualization of the mucosa in endoscopy include chromoendoscopy, confocal microscopy and optical coherence tomography. [citation needed]

Following this, the endoscope is advanced a small distance in front of the overtube and the balloon at the end is inflated. Using the assistance of friction at the interface of the enteroscope and intestinal wall, the small bowel is accordioned back to the overtube. The overtube balloon is then deployed, and the enteroscope balloon is deflated.
