Summary

Normal or scarred appendixes may be removed by amputation or inversion. Inversion is appealing for its high degree of asepsis, but criticized for the possibility of organ retention with consecutive invagination. The risks and advantages of amputation appear to be exactly the opposite. For objective comparison, a prospective study was undertaken, using both procedures in 400 cases of solitary and 40 cases of complementary appendectomies at a random number key. Wound infection was observed in 0.5% following inversion, in 8% following amputation as a solitary procedure. Both methods were equally followed by wound infections when performed as complementary procedures. However, inversion was free of enterogenous infection in all cases. Technical precautions were taken to facilitate sloughing of inverted appendixes. No clinical symptoms indicating retention or correlated complications were observed.

Zusammenfassung

Zur Entfernung blander oder geringfügig vernarbter Wurmfortsätze stehen zwei alternative Verfahren zur Verfügung: „Amputations”-Appendektomie und Inversions-„Appendektomie”. Als Vorteil der Inversion gilt der hohe Grad des Asepsis, als Nachteil die mögliche Organretention mit konsekutiver Invagination. Die Risken der Amputation verhalten sich diametral entgegengesetzt. Zur Beurteilung dieser Fragen wurden beide Verfahren —als Solitäreingriffe bei 400, als Ergänzungseingriffe bei 40 Patienten — in Form einer prospektiv randomisierten Studie gegenübergestellt. Die Inversion zog als Zieleingriff in 0,5%, die Amputation in 8% Wundheilungsstörungen nach sich. Beide Methoden waren als Ergänzungseingriffe in vergleichbarer Zahl von Infekten belastet. Nach Inversion trat keine Wundinfektion durch enterogene Keime auf. Unsere Operationstechnik nahm darauf Bedacht, Organretentionen hintanzuhalten. Im eigenen Krankengut traten keine diesbezüglichen Beschwerden auf.
