Wichtig ist es, maligne Grunderkrankungen sicher auszuschlie\u00dfen, sodass die Diagnostik immer eine Gastroskopie einschlie\u00dflich Probenentnahme zum Ausschluss einer sekund\u00e4ren Motilit\u00e4tsst\u00f6rung umfasst. Die hochaufl\u00f6sende Manometrie stellt den Goldstandard in der Diagnostik prim\u00e4rer Motilit\u00e4tsst\u00f6rungen der Speiser\u00f6hre dar und liefert auch Auskunft \u00fcber m\u00f6gliche gastro\u00f6sophageale Abflussobstruktionen.<\/jats:p><jats:p>Wir berichten im Folgenden \u00fcber eine 73-j\u00e4hrige Patientin mit rasch progredienter Schluckst\u00f6rung und initial endoskopisch unauff\u00e4lligem Schleimhautbefund bei zun\u00e4chst funktionell imponierender Enge im Bereich des gastro\u00f6sophagealen \u00dcberganges. Bei auff\u00e4lliger Manometrie mit nachgewiesener gastro\u00f6sophagealer Abflussobstruktion (EGJOO = esophagogastral junction outflow obstruction) konnten wir in einer wiederholten Magenspiegelung ein unterminierend wachsendes Kardiakarzinom als Ursache der Beschwerden diagnostizieren. Unser Fallbeispiel demonstriert, dass eine wiederholte endoskopische Diagnostik unter Kenntnis des manometrischen Befundes hilfreich ist, um der Ursache einer Dysphagie weiter auf den Grund zu gehen.<\/jats:p>","DOI":"10.1055\/a-2596-9018","type":"journal-article","created":{"date-parts":[[2025,7,12]],"date-time":"2025-07-12T00:52:57Z","timestamp":1752281577000},"page":"756-759","source":"Crossref","is-referenced-by-count":0,"title":["B\u00f6se auf den zweiten Blick \u2013 das versteckte Kardiakarzinom"],"prefix":"10.1055","volume":"63","author":[{"given":"Susanne M.","family":"H\u00fcrtgen","sequence":"additional","affiliation":[{"name":"Klinik f\u00fcr Innere Medizin und Gastroenterologie, Rhein-Maas Klinikum, W\u00fcrselen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Til","family":"Bubenzer","sequence":"additional","affiliation":[{"name":"Gastroenterologische Praxis, Aachen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Amjad","family":"Naami","sequence":"additional","affiliation":[{"name":"MVZ Institut f\u00fcr Pathologie W\u00fcrselen-Aachen, W\u00fcrselen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jens J.
