National referral center for EBUS / EUS

An accurate diagnosis,
without open surgery.

If you've been told you have enlarged lymph nodes in the mediastinum, a mass near the bronchi or suspected lung cancer, I know the uncertainty weighs more than any symptom. Here's good news: today we can reach a precise diagnosis through a simple bronchoscopy or endoscopy — no cuts, no scars and, in most cases, going home the same day.

EBUS (endobronchial ultrasound) and EUS (endoscopic ultrasound) let me see through the wall of the airway and the esophagus, and take biopsies from any area of the mediastinum with millimetric precision, guided by real-time ultrasound.

What are EBUS and EUS?

Two sister tools, one shared goal: reaching a diagnosis with the least possible aggression to your body.

🫁

EBUS — Endobronchial Ultrasound

A flexible bronchoscope with a tiny ultrasound probe at its tip travels through your trachea and bronchi. With it I see in real time the lymph nodes and masses that lie beyond the bronchial wall and take samples with a fine needle (EBUS-TBNA), from exactly the spot we need to study.

✓ Lung cancer staging (key to choosing the best treatment)
✓ Biopsy of mediastinal and hilar lymph nodes
✓ Diagnosis of sarcoidosis, lymphoma, tuberculosis and metastases
✓ Central masses near the airway

🔍

EUS — Endoscopic Ultrasound

The same principle, but through the esophagus. EUS gives me access to areas of the mediastinum that EBUS cannot reach — the posterior and inferior mediastinum, the left adrenal gland and lesions near the esophagus. Together, EBUS + EUS cover virtually the entire mediastinum.

✓ Biopsies of the posterior and inferior mediastinum
✓ Assessment of esophageal tumors and their depth
✓ Complementary lung cancer staging
✓ Access to structures beyond the reach of bronchoscopy

💡 Combining EBUS + EUS in a single session allows us to biopsy nodes and lesions from any part of the mediastinum, avoiding in the vast majority of cases a diagnostic surgery (mediastinoscopy or thoracotomy).

Why with Dr. Castaño?

Experience matters.
And here it shows.

EBUS is only as good as the hands and judgment of whoever performs it. I have carried out more than 100 EBUS procedures at Pablo Tobón Uribe Hospital, one of the highest-complexity hospitals in the country, which has established us as a national referral center: colleagues from all over Colombia refer their patients for these studies.

My training in interventional bronchoscopy-endoscopy in Montreal, Canada (CETOC Fellowship, Université de Montréal) let me master these techniques at one of the highest-volume centers in North America, and bring those standards to Medellín.

🎯 Precision that reassures

The needle is guided by real-time ultrasound: we take the sample from exactly the node or mass we need, not "blindly." That means reliable diagnoses from the very first attempt.

🛌 Sedation, not pain

The procedure is done under sedation or general anesthesia in high-complexity suites. You'll feel nothing and remember nothing. It lasts between 30 and 60 minutes.

🏠 Home the same day

In the vast majority of cases it is outpatient: a few hours of observation and you go home. No wounds, no stitches, no prolonged hospital stay.

Step by step

Your procedure, no surprises

Knowing what to expect reduces anxiety. This is exactly what your experience will be like:

STEP 1 · CONSULTATION

We review your case together

I analyze your imaging (CT, PET-CT) and explain clearly what we're looking for, why EBUS/EUS is the best option, and answer all your questions. Also by telemedicine if you live outside Medellín.

STEP 2 · THE DAY OF THE PROCEDURE

Sedation and procedure (30–60 min)

You arrive fasting at Pablo Tobón Uribe Hospital. Under sedation, I perform the EBUS and/or EUS with real-time ultrasound guidance. You simply sleep; we take care of the rest.

STEP 3 · RECOVERY

Home the same day

After a few hours of observation, you go home. A mild sore throat for a day or two is normal. Nothing more.

STEP 4 · RESULTS AND PLAN

Clear answers, a concrete plan

When the pathology result comes in, we meet to explain it without jargon and define the next step together. If cancer is confirmed, the same team that diagnosed you accompanies you through treatment.

Is it for you?

EBUS/EUS may be your answer if…

✓
A CT or PET-CT showed enlarged mediastinal lymph nodes and no one yet knows why.
✓
You have a lung nodule or mass and need to know whether it is cancer and whether it has spread.
✓
You were diagnosed with lung cancer and need precise staging before deciding on treatment.
✓
Sarcoidosis, lymphoma or nodal tuberculosis is suspected and biopsy confirmation is required.
✓
You were offered a diagnostic surgery and want to know whether a less invasive alternative exists.

If you're facing possible lung cancer…

I want you to know something important: a precise, early diagnosis radically changes the outlook. Staging with EBUS/EUS defines exactly what stage the disease is at, and that determines the right treatment from day one. Every week counts — but so does every well-made decision. You are not alone in this.
