Different interventional procedures are used for early gastrointestinal neoplasia depending on the type of tumor. Minimally invasive methods such as endoscopic mucosal resection (EMR) or endoscopic submucosal dissection (ESD) are particularly gentle, while radical surgery is necessary if deep tumor invasion is suspected. The choice of procedure is guideline-based, based on the type of growth and gross morphology (Paris classification) as well as additional features (e.g. JNET or pit-pattern classification). However, the subjective assessment of the three-dimensional (3D) tumor structure based on two-dimensional (2D) images from flexible endoscopy often leads to varying diagnoses. Elasticity measurements, for example by endosonographic elastography, help to identify deep invasions (tumor hotspots), but require a subjective combination with the white light endoscopy images by the physician, which can lead to errors. EndoPlan-3D therefore creates a Klgestützte 3D reconstruction with integrated tissue elasticity, which is provided via interactive technologies and thus increases the precision of surgical planning.
