在经口内窥镜肌切开术中使用剪刀治疗贲门失弛缓症

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.
