Endoluminal suturing devices are advanced endoscopic tools used to place sutures inside the lumen of the gastrointestinal (GI) tract without open surgery. They enable physicians to close defects, reduce tissue volume, or modify anatomy through a flexible endoscope.

They are widely used in therapeutic endoscopy and minimally invasive GI procedures.

Principle

These devices work by:

• Passing a suturing system through a flexible endoscope

• Grasping GI tissue from inside the lumen

• Placing full-thickness or partial-thickness stitches

• Tying or cinching sutures internally to approximate tissue
