Banding is a medical procedure which uses elastic bands for constriction. Banding may be used to tie off blood vessels in order to stop bleeding, as in the treatment of bleeding esophageal varices. [1] The band restricts blood flow to the ligated tissue, so that it eventually dies and sloughs away from the supporting tissue.
Esophageal varices seven days after banding, showing ulceration at the site of banding. The upper two thirds of the esophagus are drained via the esophageal veins, which carry deoxygenated blood from the esophagus to the azygos vein, which in turn drains directly into the superior vena cava. These veins have no part in the development of ...
It is a temporary measure: ulceration and rupture of the esophagus and stomach are recognized complications. [4] [5] A related device with a larger gastric balloon capacity (about 500 ml), the Linton–Nachlas tube, is used for bleeding gastric varices. It does not have an esophageal balloon.
The surgical insertion of an adjustable gastric band is often referred to as a lap band procedure or band placement. First, a small incision (typically less than 1.25 cm or 0.5 in.) is made near the belly button. Carbon dioxide (a gas that occurs naturally in the body) is introduced into the abdomen to create a work space for the surgeon. Then ...
Esophageal varices often do not have symptoms until they rupture. A ruptured varix is considered a medical emergency because varices can bleed a lot. A bleeding varix may cause a person to vomit blood, or suffer shock. To deal with a ruptured varix, a band may be placed around the bleeding blood vessel, or a small amount of a clotting agent may ...
Treatment (banding/sclerotherapy) of esophageal varices Injection therapy (e.g., epinephrine in bleeding lesions) Cutting off of larger pieces of tissue with a snare device (e.g., polyps , endoscopic mucosal resection)
This type of weight loss surgery is losing favor as more doctors begin using the adjustable gastric band. [1] The newer adjustable band does not require cutting into the stomach and does not use any staple lines, thus making it a much safer alternative.
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 .
