Ενδοσκοπικό Τμήμα

Οι ενδοσκοπήσεις, (διαγνωστικές ή επεμβατικές), διενεργούνται με καταστολή υπό συνεχές monitoring όπως επιβάλλουν οι διεθνείς κατευθυντήριες οδηγίες και τα πρωτόκολλα καταστολής, καθώς το ιατρείο φέρει όλον τον εξοπλισμό που απαιτείται για την ασφάλεια του ασθενούς.

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.

Gastroenterologist – Hepatologist M.D.

I am Alexandros Spyrantis, Gastroenterologist and Hepatologist M.D., with a private practice in Ilioupoli, Athens. I am also a Gastroenterologist Associate at the 1st Department of Gastroenterology and Interventional Endoscopy at IASO General Clinic.

I graduated from the Faculty of Medicine at the University of Latvia in Riga and subsequently completed my specialist training in Gastroenterology and Hepatology in Greece. My specialist training included the Hepato-Gastroenterology Department of G.O.N.K. “Agioi Anargyroi”, as well as clinical training at the Gastroenterology Department of General Hospital of Nikaia “Agios Panteleimon”. Prior to specialising in Gastroenterology, I trained in Internal Medicine, gaining broad clinical experience in the overall assessment and management of patients.

Gastrointestinal endoscopy is a particular area of professional interest. I have completed the Hellenic Gastroenterology Society’s Endoscopy School and have participated in hands-on training in invasive endoscopic techniques. I also regularly participate in scientific conferences and educational programmes in Greece and abroad, with a focus on Gastroenterology, Hepatology and Endoscopy.

In my clinical practice, I assess and manage a wide range of gastrointestinal and liver conditions, including gastroesophageal reflux disease, indigestion, gastritis, Helicobacter pylori infection, peptic ulcer disease, abdominal pain, bloating, irritable bowel syndrome, constipation, diarrhoea and changes in bowel habits. I also evaluate gastrointestinal bleeding, colorectal polyps, diverticular disease and inflammatory bowel diseases such as Crohn’s disease and ulcerative colitis, as well as liver and biliary disorders.

I place particular emphasis on careful history-taking and a structured diagnostic approach. I believe that patients should clearly understand what may be causing their symptoms, why a particular investigation is recommended and what the next steps should be.

For this reason, I aim to give each patient sufficient time to discuss their symptoms, concerns and expectations. I explain the diagnosis and available treatment options in clear and understandable terms, while tailoring the medical approach to each individual patient.

My approach combines current medical knowledge with personalised care. I believe that effective medical care should take into account not only the clinical findings and scientific evidence, but also the individual needs and circumstances of each patient.

Alongside my clinical work, I maintain an active interest in medical research and continuing professional education. I have participated in scientific studies, presentations and posters at Greek and international conferences, with topics including inflammatory bowel disease, hepatology, gastrointestinal endoscopy and a range of gastrointestinal conditions.

My aim is to provide patients with medical care that combines scientific expertise, careful diagnostic assessment, up-to-date knowledge and clear, compassionate communication.

For me, good medical care does not end with establishing a diagnosis. It also means providing clear information, an appropriate management plan and building a relationship of trust between doctor and patient.
