Hello everyone, a family member has been dealing with some stomach issues lately, and our family doctor recommended an endoscopy, which includes what we commonly know as a gastroscopy and colonoscopy. Since we have private health insurance, we had many options, so I started researching which hospitals have the best technology and expertise. After all, it’s an invasive procedure, so finding a reliable doctor and hospital is crucial.
After doing some homework, I discovered that Spain is quite advanced in treating digestive diseases and in endoscopic technology. Based on local medical reports, news, and discussions on patient forums, I’ve compiled a list of highly-regarded hospitals for endoscopies in Spain. This is for your reference, just my personal findings and not an official ranking.
Top-Tier Public Hospitals
The overall quality of public hospitals is actually very high, especially the teaching hospitals where many top specialists work. If your family doctor can refer you to one of these, you shouldn’t hesitate.
- Hospital Clínic de Barcelona: This is undoubtedly a top-tier institution not just in Spain, but in all of Europe. Their Institute of Gastroenterology and Hepatology is renowned, and their endoscopy technology sets the standard. Many complex surgeries and diagnostics are performed here.
- Hospital Universitario La Paz: One of Madrid’s flagship hospitals, its Gastroenterology Department consistently ranks high in patient satisfaction and technological innovation. They are particularly experienced in diagnosing and treating digestive diseases in children.
- Hospital General Universitario Gregorio Marañón: Another giant in Madrid with strong comprehensive capabilities. Its Gastroenterology Department is also one of its key specialties, known for frequent equipment upgrades and a powerful medical team.

How to Choose a Private Hospital?
For most people with private health insurance, choosing a private hospital is faster and more convenient. Private hospitals generally offer a better environment and service, with more flexible appointment scheduling. For endoscopic procedures, the following are some of the most frequently mentioned:
- Clínica Universidad de Navarra: With campuses in Madrid and Pamplona, this is arguably the top private hospital in Spain. Although it’s expensive, its equipment, technology, and specialists are world-class. It’s the top choice if your budget and insurance coverage allow.
- Hospital Quirónsalud Madrid/Barcelona: Quirónsalud is the largest private healthcare group in Spain, with hospitals in major cities. The gastroenterology departments at their flagship hospitals in Madrid and Barcelona are excellent. They offer easy appointments and wide insurance coverage, making them a well-balanced choice.
- HM Hospitales: This is another large hospital group, with a strong presence in the Madrid region. Their services and facilities are also very modern. For example, the HM Sanchinarro campus is popular, and many people have had positive experiences there.
I’ve put together a simple table to help you compare the pros and cons of public and private hospitals, so you can decide based on your own situation.
| Feature | Public Hospitals | Private Hospitals |
| Cost | Free | Expensive |
| Waiting Time | Long (weeks to months) | Short (usually days to a week) |
| Technical Skill | Top-tier, especially for complex cases | Excellent, equipment is often state-of-the-art |
| Service & Environment | Basic, can be crowded | Superior, often like a hotel |
| Choice of Doctor | Cannot choose your doctor | Can freely choose a specialist |
For non-urgent and non-complex conditions, choosing a conveniently located, well-regarded private hospital covered by your insurance is often the most cost-effective option for routine check-ups. I hope this information is helpful, and I welcome everyone to add their own experiences and suggestions in the discussion!
