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.
In situations where portal pressures increase, such as with cirrhosis, there is dilation of veins in the anastomosis, leading to esophageal varices. [3] Splenic vein thrombosis is a rare condition that causes esophageal varices without a raised portal pressure. Splenectomy can cure the variceal bleeding due to splenic vein thrombosis.

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.
Somatostatin and octreotide, while recommended for varicial bleeding, have not been found to be of general use for non variceal bleeds. [4] After treatment of a high risk bleeding ulcer endoscopically giving a PPI once or a day rather than as an infusion appears to work just as well and is less expensive (the method may be either by mouth or ...
The National Institute for Health and Clinical Excellence (NICE) produced clinical guidelines in July 2013 recommending that all people with symptomatic varicose veins (C2S) and worse should be referred to a vascular service for treatment. [33] Conservative treatments such as support stockings should not be used unless treatment was not possible.
Anorectal varices are collateral submucosal blood vessels dilated by backflow in the veins of the rectum. [1] Typically this occurs due to portal hypertension which shunts venous blood from the portal system through the portosystemic anastomosis present at this site into the systemic venous system .
Portal hypertension is defined as increased portal venous pressure, with a hepatic venous pressure gradient greater than 5 mmHg. [3] [4] Normal portal pressure is 1–4 mmHg; clinically insignificant portal hypertension is present at portal pressures 5–9 mmHg; clinically significant portal hypertension is present at portal pressures greater than 10 mmHg.

People are usually stratified into having either variceal or non-variceal sources of upper gastrointestinal hemorrhage, as the two have different treatment algorithms and prognosis. [citation needed] The causes for upper gastrointestinal hemorrhage include the following: Esophageal causes (gastrorrhagia): Esophageal varices; Esophagitis ...
