Method for treating esophageal variceal bleeding through sclerosis therapy

Abstract

The invention discloses a method for treating esophageal variceal bleeding through sclerosis therapy, and relates to the field of medical technologies. A transparent cap is arranged and fixed to an endoscope end firstly before treatment, the oesophagus is flushed through 0.9% of ice sodium chloride injection firstly after an endoscope is inserted, the visual field is made to be kept as clear as possible, and the esophageal variceal vein degree, range, red-color sign and the bleeding portion are determined; starting from the bleeding vein or the vein only with red/white venous thrombosis or the vein with clear varix and large bleeding possibility, the vein to be injected is placed at the center of the visual field of the endoscope, the transparent cap end is tightly attached to the vein, the target vein is relatively fixed, and a syringe needle stretches out of an endoscope apex pliers channel and punctures the vein directly from the position below the bleeding point. According to the method, the transparent cap assists the endoscope in treating esophageal variceal bleeding through the sclerosis therapy, the visual field is kept clear, the target vein is fixed, compression is convenient to conduct after injection, and the rebleeding rate generated after compression is reduced obviously.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a method for sclerotherapy for rupture and bleeding of esophageal varices. Background technique [0002] Esophageal variceal bleeding (EVB) is one of the most serious complications of portal hypertension due to liver cirrhosis, with a large amount of bleeding and high mortality. Conservative treatment in internal medicine has a low rate of emergency hemostasis, a high rate of rebleeding, and recurrence after drug withdrawal. However, surgical treatment is prone to complications, aggravating liver function damage, and the long-term survival rate is not ideal. Esophageal and gastric varices occur in 40% of patients with liver cirrhosis, the annual incidence of variceal bleeding is 5% to 15%, the 6-week mortality rate is 20%, and the rebleeding rate within 1 year is as high as 60%. [0003] There is no radical treatment for esophageal varices due to liver cirrhosis. At present, t...

Problems solved by technology

If there is active bleeding after injection, the hemostasis can be effectively suppressed by rotating the sleeve. However, installing a transparent sleeve outside the endoscope body will increase the pain of the patient’s pharynx discomfort. With the Sliding Tube method, due to the cumbersome application of the balloon or the sleeve, which increases the pain of the patient, it has basically been eliminated. The free-hand technique is quick and convenient to operate and has been widely used. When the needle hole bleeds after the injection, insert the endoscope Stomach cavity, press the suction button of the endoscope to continue to attract, which plays the role of compression by the endoscope body, but the hemostatic effect of the endoscope body is limited
