L'échoendoscopie (EUS) à l'hôpital HYGEIA à Maroussi, Athènes, est utilisée pour examiner les parois du tube digestif et les organes environnants tels que le pancréas et les voies biliaires. Ce diagnostic associe l'endoscopie traditionnelle à l'imagerie par ultrasons en temps réel pour détecter les tumeurs et stadifier les cancers. L'hôpital détient le « Gold Seal of Approval » de la Joint Commission International (JCI), qu'il conserve depuis 2010.
L'examen aide à identifier les tumeurs du pancréas et des voies biliaires ou à évaluer les excroissances sous-muqueuses du tube digestif. Pendant l'intervention, un endoscope fin muni d'une sonde à ultrasons est inséré par la bouche. La clinique réalise également des cytoponctions à l'aiguille fine (EUS-FNA) pour recueillir des échantillons de tissus ou de liquide à des fins d'analyse. L'hôpital HYGEIA a réalisé plus de 2 500 procédures EUS-FNA avec un taux de diagnostic de malignité de 95 %.
L'établissement est l'un des rares centres spécialisés en Grèce à proposer à la fois l'examen par ultrasons et la cytoponction à l'aiguille fine en une seule visite. Bien que l'examen lui-même soit immédiat, le traitement des résultats cytologiques des échantillons de tissus prend généralement plusieurs jours. Vous pouvez demander une consultation pour ce diagnostic via la plateforme Bookimed.

HYGEIA Hospital is a private hospital in Marousi, Athens, Greece. A group of Greek physicians founded it in 1975. The institution operates as a major medical center within a single building. It provides specialized diagnostic and treatment pathways across multiple medical fields.
HYGEIA Hospital employs 924 staff members to support patient care. The hospital holds the Joint Commission International (JCI) Gold Seal of Approval. It has maintained this certification continuously since 2010.
To protect patients, the hospital uses strict safety controls for high-risk medications. These protocols include special labeling and mandatory confirmation procedures. The European Cancer Organisation awarded the institution the INTERACT-EUROPE Gold Badge.
The hospital also holds certifications from several international medical organizations:
In 2004, the hospital opened the first PET/CT department in Greece.
The hospital provides precise cancer diagnostics using modern imaging tools. Breast cancer detection uses a dedicated Automated Breast Ultrasound (ABUS) workflow. An ABUS scan takes about 15 minutes. Combining ABUS with digital mammography increases breast cancer detection in dense breasts by 37.5%.
For complex neurological cases, the hospital features a Gamma Knife Perfexion unit. This technology performs brain radiosurgery without surgical incisions. A dedicated Pediatric and Adult Ophthalmic-Oncology Center treats eye tumors in children and adults.
The cardiac team treats complex arrhythmias and structural heart disease. Specialists perform catheter ablation to treat atrial fibrillation (irregular heart rhythm). The standard procedure lasts about 2.5 hours. Cryoablation uses extreme cold and takes less time.
During ablation, patients receive sedation. Vascular punctures use local anesthesia. About 70% of paroxysmal atrial fibrillation patients maintain normal rhythm after one procedure. For long-standing persistent cases, the success rate reaches up to 50%. The hospital also serves as a reference center for transcatheter valve treatments.
The urology department focuses on prostate care, testicular tumors, and stone diseases. Prostate cancer cure rates exceed 90% at the hospital. Specialists use multiparametric MRI to guide targeted tissue biopsies. This scan takes about 25 to 30 minutes. Treatment options include robotic-assisted surgery.
Surgeons perform radical orchiectomy to treat testicular tumors. This procedure involves surgical removal of a testicle under general anesthesia through a 5–7 cm groin incision.
For upper urinary tract stones, the team offers several minimally invasive options:
Open surgery is reserved for patients with massive stone burdens or anatomical abnormalities.
Dr. Zacharias P. Tsiamoulos directs the endoscopic microsurgery unit. The department uses IN CREM technology. This method transforms traditional endoscopy into a scarless surgical procedure. Doctors operate entirely through the gastrointestinal tract lumen.
The department partners with the HEAL Academy and the Arab Society of Gastrointestinal Endoscopy. Together, they host international courses with live cases and hands-on training.
The proctology team specializes in treating grade II and grade III hemorrhoids. Specialists perform laser hemorrhoidoplasty, a minimally invasive alternative to traditional surgery. Dr. Stylianos G. Rossonis is a key surgeon for this procedure.
The treatment uses a flexible 2 mm laser catheter. The device delivers 980 or 1470 nm radiation directly to the hemorrhoidal nodule. This energy shrinks tissue without intense pain. Full healing takes 8 to 10 weeks.
HYGEIA Hospital invests in specialized medical hardware for diagnostic accuracy. The imaging department features the NAEOTOM Alpha Pro, a photon-counting CT scanner. This system provides high-contrast images at lower radiation doses.
For joint replacements, orthopedic surgeons use the MAKO robotic system. This platform helps plan and execute partial or total knee and hip replacements.
The hospital also has modern equipment for distinct therapeutic areas:
These systems are integrated inside multispecialty hybrid operating rooms.
The hospital belongs to the Hellenic Healthcare Group (HHG) network. International patients can manage their medical data through the my-Ygeia digital health file. This platform provides immediate online access to laboratory and imaging results. Patients can view records from all participating HHG facilities and Healthspot diagnostic centers.
