Zusammenfassung
Einleitung: 5 % aller gastrointestinalen Blutungen sind obskure gastrointestinale Blutungen (OGIB), deren Ursache mit den herkömmlichen endoskopischen Methoden nicht geklärt werden kann. Früher mussten die Chirurgen bei Fällen von wiederholt auftretenden, overten Blutungen eine Laparotomie ohne Diagnose durchführen. Das Ziel unserer retrospektiven Studie war, die Wirksamkeit der chirurgischen Therapie bei OGIB-Patienten, die mittels Kapselendoskopie (CE) untersucht worden waren, zu bestimmen. Methodik: In 2 Zentren haben wir binnen 3 Jahren die Kapselendoskopie-Untersuchungen bei 61 Patienten ausgewertet, nach Panendoskopie und Koloskopie ohne Diagnosefindung. Die CE-Befunde wurden entsprechend der Blutungsquelle in 3 Gruppen eingeteilt: definitive Blutungsquelle (48), unklares Blutungspotenzial (5) und negativer Befund (8). Chirurgische Therapie wurde in 18 Fällen mit definitiven Blutungsquellen eingeleitet. Ergebnisse: Das durchschnittliche Lebensalter der 7 männlichen und 11 weiblichen Patienten, die operiert wurden, betrug 63,4 (± 10,69) Jahre. Die Zeit zwischen dem Auftreten der ersten klinischen Symptome und dem Datum der Operation betrug im Durchschnitt 18,2 (± 26,11) Monate. Während dieses Zeitraums wurden die Patienten in durchschnittlich 6 (± 7,96) Fällen ins Krankenhaus aufgenommen. In 17 Fällen (94 %) bestätigten die chirurgischen Eingriffe und die pathologischen Befunde die mithilfe der CE entdeckten definitiven Blutungsquellen. In einem Fall von Angiodysplasie-Blutung mit negativem pathologischen Befund traten im Nachuntersuchungszeitraum keine erneuten Blutungen auf. Schlussfolgerungen: CE hat große Auswirkungen auf die chirurgischen Resultate bei Patienten mit OGIB. Die korrekte Lokalisierung der Blutungsquellen aufgrund unserer Untersuchungen bot in allen Fällen eine angemessene Unterstützung, um eine optimale Resektion des Dünndarms durchzuführen.
Abstract
Background: Obscure gastrointestinal bleeding (OGIB) that cannot be established applying traditional endoscopic methods represents 5 % of all gastrointestinal bleedings. Earlier, in cases of recurrent, overt bleedings the surgeons had to perform a laparotomy “blind” without diagnosis. The aim of our retrospective study was to analyse the effectiveness of surgical therapy in patients with OGIB investigated with capsule endoscopy (CE). Methods: During 36-month period at two workplaces capsule endoscopy studies were evaluated in 61 patients with OGIB who had undergone non-diagnostic panendoscopy and colonoscopy. CE findings were divided into three groups according to the bleeding source: definitive bleeding source (48), uncertain bleeding potential (5) and negative findings (8). Surgical therapy was initiated in 18 cases with definitive bleeding sources. Results: The mean age of 7 male and 11 female patients operated on was 63.4 (± 10.69) years. The period between the first clinical symptoms and the date of the operation was an average of 18.2 (± 26.11) months. During this period patients were hospitalized in an average of 6 (± 7.96) cases. In 17 cases (94 %) the surgical and pathological findings justified the definitive bleeding sources detected by CE. In one case of bleeding angiodysplasia with negative pathological findings the follow-up period without recurrent bleeding justified the validity of CE results and the success of surgical therapy. Conclusions: CE offers a high impact on the surgical results in patients with OGIB. Through our CE examinations the correct localization of the bleeding sources always provided a reasonable support to perform an optimal small bowel resection.
