Zusammenfassung
Im Rahmen einer prospektiven Untersuchung bei 20 voroperierten Patientinnen wurde
die Praktikabilität des Ersteinstichs mit einem 2/3 mm dilatierbaren STEP-Trokar (InnerDyne,
Inc., Sunnyvale, USA) im Bereich des linken Rippenbogens unter Verwendung von 2 oder
3,3 mm Minioptiken (Storz) überprüft. Bei allen 20 voroperierten Patientinnen wurden
trotz der hohen Inzidenz von periumbilikalen Netz- und Darmadhäsionen (55 %) keine
Komplikationen beobachtet. Dadurch wird bestätigt, daß die Verwendung eines Minilaparoskopes
im Bereich des linken Rippenbogenrandes bei Risikopatientinnen eine sichere und minimal
invasive Methode zur Verhinderung bzw. Senkung der Anzahl an trokarbedingten Verletzungen
beim Ersteinstich darstellt. Die Kombination mit dem 2/3 mm STEP-Einmaltrokar ermöglicht
bei klinischer Notwendigkeit ein atraumatisches Aufdilatieren und schonendes Einführen
von wiederverwendbaren 5 mm, 10 mm oder 12 mm Trokaren.
Minilaparoscopy below the left costal border with radially expanding STEP-Trocar-System
in patients with previous pelvic surgery - results of a pilot study
Summary
As a part of a prospective study of 20 patients with previous pelvic surgery, the
efficacy of using a 2/3 mm dilatable STEP device (InnerDyne, Inc., Sunnyvale, USA)
for the first insertion in the area below the left costal border was tested, using
2 or 3.3 mm minilaparoscopes (Storz). Despite the high incidence of periumbilical
omental and bowel adhesions (55 %), no complications were observed in any of the 20
patients with previous pelvic surgery. Herewith could be confirmed that the use of
a minilaparoscope in the area below the left costal border represents in high risk
patients a safe and minimally invasive method for preventing or reducing the number
of trocar-related injuries during first trocar insertion. In combination with the
use of 2/3 mm disposable STEP-trocars if clinically required an atraumatic dilation
and safe insertion of reusable 5 mm, 10 mm or 12 mm trocars is enabled.
