简介：
Overview
This article presents a protocol for performing peroral endoscopic myotomy (POEM) using a scissor-type knife. The focus is on enhancing safety and reducing technical difficulties during the procedure.
Key Study Components
Area of Science
- Endoscopic surgery
- Gastroenterology
- Esophageal disorders
Background
- POEM is a minimally invasive treatment for achalasia.
- Traditional techniques often involve needle-type knives, which can be challenging.
- Operators may face difficulties with hemostatic control during the procedure.
- Improving the method can enhance patient safety and outcomes.
Purpose of Study
- To describe a safer and easier protocol for POEM.
- To utilize a scissor-type knife for key steps in the procedure.
- To facilitate better hemostasis and reduce complications.
Methods Used
- Identification of the esophagogastric junction (EGJ).
- Measurement of distance from incisors to locate the incision point.
- Injection of saline with methylene blue into the submucosal space.
- Execution of mucosal incision, submucosal tunneling, myotomy, and hemostasis.
Main Results
- The scissor-type knife effectively facilitated the POEM procedure.
- Improved safety and reduced technical challenges were observed.
- Enhanced hemostatic control was achieved during the procedure.
- Operators reported increased confidence using the new protocol.
Conclusions
- The scissor-type knife is a viable alternative for POEM.
- This method can improve patient outcomes and procedural safety.
- Further studies may validate these findings across broader populations.
What is POEM?
Peroral endoscopic myotomy (POEM) is a minimally invasive procedure to treat achalasia by cutting the muscle at the esophagogastric junction.
How does the scissor-type knife improve POEM?
It simplifies the procedure, enhances safety, and provides better hemostatic control compared to traditional needle-type knives.
What are the main steps in the POEM procedure?
The main steps include mucosal incision, submucosal tunneling, myotomy, and hemostasis.
Why is hemostatic control important in POEM?
Effective hemostatic control is crucial to prevent excessive bleeding during the procedure, which can complicate recovery.
What challenges do operators face during POEM?
Operators may struggle with tissue plane dissection and managing bleeding, especially if they are inexperienced.
What is the significance of identifying the EGJ?
Identifying the esophagogastric junction is essential for accurate incision and successful outcomes in POEM.
