ENA gastroscopy in Germany is a look at the oesophagus, stomach and duodenum through a thin, flexible endoscope, open to patients from abroad on a hospital’s invitation. People come to it not out of curiosity but after months of heartburn, pain under the breastbone or unexplained anaemia, or after being told at home of «a suspicion» without being told of what. It takes minutes and decides a great deal: it tells gastritis from an ulcer and an early tumour, and only it puts tissue under a microscope.
Below: how it actually runs, what sedation changes, what is sampled and when results arrive, how a German protocol differs from a quick look, and how a patient from abroad gets an appointment. Overview: endoscopy of the digestive tract in Germany; not sure where to start: diagnostics in Germany.
How the examination runs
A gastroscopy in Germany follows a set sequence. You arrive with an empty stomach, talk to the doctor and sign the consent form. The throat is numbed with a spray, and a thin, flexible endoscope passes through the mouth into the oesophagus, stomach and duodenum. The look itself is usually short.
In Germany it is usually done under drug-induced sleep, most often with propofol: you feel nothing and as a rule remember nothing. The consequences: no driving that day, and a companion must take you home. In some cases, a thin endoscope through the nose, without sedation, is offered instead.
Preparation: the last meal is the evening before, nothing in the morning, so the lining can be seen. Blood thinners and diabetes medication are settled by a doctor in advance, not by a nurse on the day; never stop them on your own. If a biopsy is planned, anticoagulants are discussed separately. Details: patient information from the German institute IQWiG (in German).
What is looked for and what is sampled
Doctors look for changes that explain the symptoms and sample anything suspicious: inflammation and erosions (shallow sores); stomach and duodenal ulcers; a hiatus hernia and acid reflux; Barrett’s oesophagus, a change of its lining after years of acid; coeliac disease; sources of hidden bleeding behind anaemia; and early tumours. See also gastroenterology in Germany.
A biopsy takes a few tiny fragments with forceps through the endoscope. It does not hurt: the lining does not feel pain the way skin does. A pathologist gives the verdict; histology is not ready on the day, and the hospital tells you how many days it takes. Helicobacter pylori is tested separately, in the laboratory and by a rapid test in the endoscopy room. More: biopsy in Germany.
A thorough look differs from a quick one mainly in technique. Staining and narrow-band imaging help to spot a suspicious patch a few millimetres across. Endosonography, an ultrasound probe on the endoscope, judges how deep a lesion goes or the state of the pancreas. The endoscopist’s experience matters more than the brand of equipment.
When a gastroscopy is treatment, not diagnosis
A gastroscopy becomes treatment when the same endoscope is used to act: to stop bleeding from an ulcer, remove polyps, widen narrowings of the oesophagus, place stents (tubes holding a passage open) and remove early tumours of the lining without open surgery. That is what specialised endoscopy departments are for, and the main reason not to walk into the nearest clinic.
For the patient, looking and intervening differ: after a diagnostic look you rest until the sedation wears off and go home, while an intervention needs monitoring, often in hospital, for as long as its complexity and risk require, plus immediate admission and surgeons on standby if a complication arises. That is why such procedures happen in a hospital, not in a consulting room.
Where this is done in Germany
Specialised departments in several cities do this; the AlenMed partners below are examples, not a ranking. In Berlin, the gastroenterology department at Vivantes Klinikum im Friedrichshain, headed by Professor Alexander Wree, performs endoscopic submucosal dissection (ESD) and endoscopic removal of early tumours of the oesophagus, stomach and bowel. In Munich: the department of gastroenterology, hepatology and gastrointestinal oncology at München Klinik Bogenhausen, headed by Dr Martin Fuchs, with endoscopy and endosonography of the digestive organs, and the gastroenterology department of ISAR Klinikum, co-directed by PD Dr Holger Seidl and Professor Thomas Ochsenkühn. Seidl sits on the DGVS guideline panels for intestinal motility disorders, irritable bowel syndrome and reflux disease.
In Hamburg: internal medicine with a gastroenterology focus at Albertinen Krankenhaus under Professor Guntram Lock, whose listed fields include endoscopy and ultrasound, and the Israelitisches Krankenhaus, where endoscopy is headed by Dr Ulrich Rosien and Dr Stefan Michaelis. In Stuttgart: the department of gastroenterology, gastrointestinal oncology, hepatology and infectious diseases at Klinikum Stuttgart under Professor Jörg Albert. The hospital is matched to the diagnosis and dates.
Frequently asked questions
Does a gastroscopy hurt?
Usually not: it can be unpleasant but is normally not painful. A throat spray suppresses the gag reflex, and in Germany most patients sleep through it under sedation. Taking tissue does not hurt either: the stomach lining does not feel pain like skin.
Can I be asleep during a gastroscopy?
Yes. In Germany this is usually sedation rather than a general anaesthetic: a drug, most often propofol, goes into a vein, and you sleep through it and as a rule forget it. You must not drive that day and need a companion to take you home.
When are the results of a gastroscopy ready?
Not all at once. A rapid Helicobacter pylori test can be ready before you leave the endoscopy unit, but the pathologist’s report comes later, as histology is not available on the day. The hospital tells you how many days it takes; ask in advance, as it affects your stay.
How AlenMed organises treatment
AlenMed starts with the paperwork: earlier reports, imaging and laboratory results are translated and sent to an endoscopy department. The reply says whether a gastroscopy is needed at all or the existing one is enough, whether other examinations fit into the same trip (sometimes a colonoscopy in Germany), and how long the stay would be. Figures: cost of diagnostics in Germany.
AlenMed has 86 partner hospitals in 38 cities and 345 doctors; the company office is in Munich. A coordinator handles the visa invitation, the appointment and the interpreter, and makes sure the report and histology slides come in a form a doctor at home can use.
This material is for information only and is not an offer. Whether an examination is needed is decided by a doctor who sees the patient in person.
