简介：
Overview
This video presents underwater endoscopic injection sclerotherapy as a treatment for gastroesophageal varices (GEVs). The technique utilizes reduced esophageal peristalsis underwater to enhance the success of intravascular injections.
Key Study Components
Area of Science
- Gastroenterology
- Endoscopy
- Interventional Procedures
Background
- Gastroesophageal varices are a serious complication of liver cirrhosis.
- Traditional sclerotherapy techniques may face challenges due to esophageal movement.
- Underwater techniques could improve procedural outcomes.
- Ethical approval and informed consent were obtained for the procedure.
Purpose of Study
- To evaluate the efficacy of underwater endoscopic injection sclerotherapy for GEVs.
- To assess the impact of reduced peristalsis on injection success rates.
- To document the procedural outcomes and safety.
Methods Used
- A 57-year-old male patient with Hepatitis B virus cirrhosis was treated.
- Room temperature water was infused into the esophagus to create an underwater environment.
- Lauromacrogol and methylene blue were injected into the varices.
- Cyanoacrylate was used to occlude the puncture site post-injection.
Main Results
- All varices were successfully filled with the injected mixture.
- No signs of re-bleeding or complications were observed during follow-up.
- Gastroscopy three months post-procedure showed nearly 100% varicocele elimination.
Conclusions
- Underwater endoscopic injection sclerotherapy is a promising option for GEVs.
- The technique enhances the stability of vision and success of injections.
- Further studies may validate its effectiveness and safety in larger populations.
What is underwater endoscopic injection sclerotherapy?
It is a technique used to treat gastroesophageal varices by injecting a sclerosing agent in an underwater environment.
What are gastroesophageal varices?
They are dilated veins in the esophagus that can bleed due to liver cirrhosis.
How does reduced peristalsis help in the procedure?
It stabilizes the vision and increases the success rate of intravascular injections.
What was the outcome of the procedure?
The procedure resulted in nearly 100% elimination of varices without complications.
Is this procedure safe?
Yes, no complications were observed during the follow-up period.
What is the significance of using methylene blue?
Methylene blue helps to visualize the injected varices and confirm successful treatment.
