Endoscopy Shows the exact site of the bled
Another image and video of the site of bled, two scars are observed of the previous treatment.
Bleeding from the varices in the region of the gastroesophageal junction is a life threatening medical emergency usually occurring in the setting of cirrhosis and portal hypertension. The risk of bleeding is related to the degree of portal hypertension and variceal size. It often occurs without obvious precipitating cause. The usual presentation is massive hematemesis with or without melena. However, many patients with varices bleed from other lesions such as peptic ulcers or gastritis.

Endoscopic application of rubber band onto the bleeding site. Technique uses a device attached to the tip of the endoscope that allows the varix to be suctioned into a banding chamber, whereupon an elastic band is then deployed around the base of the captured varix. After 3 to 7 days the ligated tissue sloughs, leaving a shallow ulceration with scar tissue.

The varix was successfully ligated.
Endoscopic variceal ligation is associated with lower rebleeding rates and a lower frequency of esophageal strictures. Fewer sessions are required to achieve variceal obliteration when compared to sclerotherapy. Endoscopic variceal ligation is considered the endoscopic treatment of choice in the prevention of rebleeding. Sessions are repeated at 7- to 14-day intervals until variceal obliteration (usually 2-4 sessions).

The image displays several scar with fibrin at the cardias. The portal venous system, formed by the confluence of the superior mesenteric vein and the splenic vein ( drains the stomach, the large and small intestine, the pancreas, and the spleen. An important feature of this system is that a number of its tributaries also communicate with the systemic circulation. These include the intrinsic and extrinsic veins of the gastroesophageal junction; hemorrhoidal veins of the anal canal; paraumbilical veins and the recanalized falciform ligament; the splenic venous bed and the left renal vein; and the retroperitoneum. In portal hypertension, these venous collaterals dilate and allow portal venous blood to return to the systemic circulation. Clinically, the most significant collaterals are the intrinsic veins of the gastroesophageal junction, which are located close to the mucosal surface. They are the collaterals most likely to bleed when dilated because of increased blood flow.

It is essential to identify and treat those patients at highest risk because each episode of variceal hemorrhage carries a 20% to 30% risk of death, and up to 70% of patients who do not receive treatment die within 1 year of the initial bleeding episode.

Banding of Esophageal Varices.
This endoscopic sequence displays multiple images and video clips concerning the technique of banding of esophageal varices. A 65 year-old female who ten years ago presented ascitis due to Ovarian carcinoma, for which she underwent chemotherapy. Apparently the carcinoma was overcamo, and she had been asymptomatic ever since. Ten days previously to the endoscopy, the patient presented ascitis. A CAT scan confirmed the ascitis and micro nodular cirrhosis was detected. We found multiple varices when we performed an upper endoscopy, never had bleeding. Primary prophylaxis: Patients with cirrhosis who have esophageal varices but who have never had a bleeding episode may be treated medically or endoscopically. Without treatment, approximately 30% of cirrhotic patients with varices bleed and this risk is reduced by approximately 50% with therapy.

The cardias presents varices; some with the red sign. Studies of endoscopic therapy with ligation (endoscopic banding) demonstrate that in select patients (those with large varices), endoscopic banding may reduce the risk of first bleeding episode when compared with propranolol. Patients with large varices may benefit from a combination of banding with nonselective beta blockers. Secondary prophylaxis: After an initial variceal bleed, the risk of a second bleed is high and therapy is warranted to reduce the risk of rebleeding. The options are similar to those for primary prophylaxis.

Cardias in retroflexed view, there are many varices with the red sign, meaning that a possible bleeding was near.
The combination of endoscopic therapy with medical therapy is the initial approach to prevent variceal rebleeding. Endoscopic banding is preferred to sclerotherapy because banding is associated with lower bleeding rates and fewer complications.

Banding of Esophageal Varices.
Narrow endoscopic view through the rubber band delivery attachment placed on the tip of the endoscope. The variceal banding technique is similar to hemorrhoid banding and involves placing small elastic bands around varices in the distal 5 cm of the esophagus. Varices are suctioned into the banding device and bands are released around the base of the varix by pulling a trip wire via the biopsy channel. The advantages of band ligation over sclerotherapy include fewer local complications (secondary bleeding from ulcers or strictures), no systemic side effects, and the need for fewer treatments for variceal obliteration. Some of the drawbacks of band ligation include a restricted endoscopic view (due to the banding device and blood pooling within the hood mechanism), difficulty-performing treatments in the retroflexed position in the fundus of the stomach.

Multiple studies have demonstrated that variceal ligation has a remarkably low complication rate. A number of studies have been completed to compare the efficacy and safety of endoscopic sclerotherapy versus endoscopic variceal ligation. These studies demonstrate that ligation is equally as effective as sclerotherapy in achieving control of acute variceal bleeding. rebleeding and mortality are less after variceal ligation. Also, the number of procedures required to achieve obliteration of varices is less with variceal ligation than with sclerotherapy in nearly all comparative studies. Finally, complications, both minor and major, appear to be less with variceal ligation than sclerotherapy.
