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.
This is in addition to endoscopic banding or sclerotherapy for the varices. [13] If this is sufficient then beta blockers and nitrates may be used for the prevention of re-bleeding. [13] If bleeding continues, balloon tamponade with a Sengstaken-Blakemore tube or Minnesota tube may be used in an attempt to mechanically compress the varices. [13]
This leads to varices in the esophagus and stomach, which can bleed; B) a needle has been introduced (via the jugular vein) and is passing from the hepatic vein into the portal vein; c) the tract is dilated with a balloon; D) after placement of a stent, portal pressure is normalized and the coronary and umbilical veins no longer fill.
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) Application of cautery to tissues; Removal of foreign bodies (e.g., food) that have been ingested
The use of the tube was originally described in 1950, [1] although similar approaches to bleeding varices were described by Westphal in 1930. [2] With the advent of modern endoscopic techniques which can rapidly and definitively control variceal bleeding, Sengstaken–Blakemore tubes are rarely used at present.
Sclerotherapy, a minimally invasive procedure that uses chemicals to shrink varicose veins through endoscopy, was later enhanced with the introduction of variceal band ligation. Technological advancements also led to pharmacological therapies and interventional radiologic procedures like transjugular intrahepatic portosystemic shunt (TIPS ...
Endoscopic image of esophageal varices being ligated with rubber bands. The varix being ligated has a longitudinal red mark on it, termed the wale mark. A wale mark, red wale sign or wale sign is an endoscopic sign suggestive of recent hemorrhage, or propensity to bleed, seen in individuals with esophageal varices at the time of endoscopy.
