Το ιατρείο φέρει σύγχρονο ενδοσκοπικό εξοπλισμό με ψηφιακό επεξεργαστή εικόνας που επιτρέπει την καταγραφή φωτογραφιών κατά τη διάρκεια της ενδοσκόπησης.

Επίσης η παρουσία χειρουργικής διαθερμίας επιτρέπει την διενέργεια πολυποδεκτομών κατά τη διάρκεια της ενδοσκόπησης χωρίς να χρειάζεται ο ασθενής να υποβληθεί σε επαναληπτική εξέταση.

Η διαδικασία είναι αναίμακτη, ανώδυνη και αξιόπιστη, καθώς πραγματοποιείται μέσω της ανάλυσης της αναπνοής του ασθενούς μετά την πρόσληψη ειδικού υγρού υποστρώματος. Με το Gastrolyzer H2, μπορούμε να εντοπίσουμε τις αιτίες πίσω από τα πιο συνηθισμένα γαστρεντερολογικά προβλήματα, όπως φούσκωμα, τυμπανισμός, μετεωρισμός και δυσπεψία. Αυτό επιτρέπει την αποφυγή των εμπειρικών θεραπειών και την εφαρμογή στοχευμένων και αιτιολογικών λύσεων, βελτιώνοντας την ποιότητα ζωής των ασθενών και μειώνοντας την ταλαιπωρία τους.
