Initial experience with a novel endoscopic device allowing intragastric manipulation and plication

Area of Science:

• Minimally Invasive Surgery
• Gastroenterology
• Surgical Technology

Background:

• Natural orifice surgery faces challenges in tissue manipulation and secure closure.
• A new 6 mm diameter tissue approximation and suturing device was evaluated.
• The device aims to overcome limitations in current endoscopic surgical techniques.

Purpose of the Study:

• To assess the initial laboratory performance of a novel tissue approximation and suturing device.
• To evaluate the device's capabilities in tissue grasping, manipulation, and closure.
• To determine the potential of the device in advancing natural orifice surgical interventions.

Main Methods:

• The novel suturing device was tested in porcine and canine models.
• The device was deployed using a previously described surgical platform.
• Procedures included bimanual tissue manipulation and ex vivo gastrotomy closure.

Main Results:

• The device demonstrated robust tissue grasping and minimal trauma.
• Fully visualized anchor placement and operator-controlled tension were achieved.
• Secure closure of tissue defects and gastrotomy holes was successfully performed.

Conclusions:

• The novel suturing device shows potential for complex endoluminal and transluminal tasks.
• It may help overcome barriers in natural orifice surgical intervention development.
• Further investigation into the device's capabilities is warranted.
