Endoluminal full-thickness resection of GI lesions: a new device and technique.

Full-thickness resection techniques are of growing interest in the field of endoscopic removal of tumors or their precursors in the digestive tract. A new dedicated full-thickness resection device has been developed based on the combination of the OTSC clip, an enlarged resection cap and an integrated snare. The device prototype allows combined resection of all gastrointestinal organ wall layers in one maneuver, up to a size of 3 x 3 cm.

Wireless therapeutic endoscopic capsule: in vivo experiment.

Background And Study Aim: Capsule endoscopy is becoming well established as a diagnostic technique for the gastrointestinal tract. Nevertheless swallowable capsule devices that can effectively perform surgical and therapeutic interventions have not yet been developed. Such devices would also be a valuable support for natural orifice transluminal endoscopic surgery (NOTES).

The OTSC clip for endoscopic organ closure in NOTES: device and technique.

The closure of the gastrotomy in Natural Orifice Transluminal Endoscopic Surgery (NOTES) is a prerequisite for transgastric endoscopic procedures in the abdominal cavity. Different techniques have been proposed and are under experimental or early clinical investigation. We describe the technique of using an over-the-scope-clip system (OTSC), made of super-elastic Nitinol and a specially designed tissue-approximating double jaw endoscopic grasper for gastric closure.
