A new pull-through trocar technique for percutaneous operative endoscopy.

Area of Science:

• Gastroenterology
• Surgical Innovation
• Medical Device Technology

Background:

• Percutaneous endoscopic procedures require reliable access to the stomach.
• Existing methods may have limitations in immediate therapeutic application.
• Minimally invasive surgery aims to reduce patient trauma.

Purpose of the Study:

• To describe and evaluate a new pull-through trocar for percutaneous gastric access.
• To assess the feasibility of immediate endoscopic interventions through the trocar.
• To determine the safety and efficacy of the technique in an animal model.

Main Methods:

• A novel pull-through trocar was developed for gastric access.
• The trocar was placed similarly to percutaneous endoscopic gastrostomy (PEG) probes.
• The technique was tested in animal subjects using rigid endoscopes and instruments.

Main Results:

• The pull-through trocar successfully established percutaneous access to the stomach.
• Operative manipulations of the gastric wall were performed through the trocar.
• No severe complications were observed during the animal study.

Conclusions:

• The pull-through trocar offers a viable method for direct percutaneous gastric access.
• This technique facilitates immediate endoscopic interventions, expanding therapeutic options.
• The method represents a safe advancement in percutaneous therapeutic endoscopy and minimal invasive surgery.
