Zusammenfassung

Fragestellung:

In der laparoskopischen Chirurgie zur Behandlung von Rektumkarzinomen muss man technische Schwierigkeiten berücksichtigen. Es gibt nur wenige Studien zur Lernkurve nach einer laparoskopischen Rektumresektion.

Patienten und Methodik:

Zwischen Juni 1995 und August 2007 wurden 200 Patienten in die Studie aufgenommen, die für eine laparoskopische Rektumkarzinomresektion vorgesehen waren. Die Operationserfahrung von jedem Operateur wurde in drei Gruppen eingeteilt: 1–20 Fälle, 21–40 Fälle und ≥ 41 Fälle. Zudem wurden die Patienten chronologisch in vier Gruppen zu je 50 Patienten eingeteilt. Diese Arbeit beschreibt die Assoziation zwischen den Lernkurven (individuelle Erfahrung des Operateurs und Teamerfahrung) und den Kurzzeitergebnissen wie Operationszeit, Komplikationsrate und Krankenhausaufenthaltsdauer im Fall einer laparoskopischen Resektion wegen eines Rektumkarzinoms. Ebenfalls wurde analysiert, wie die Lernkurve verschiedene postoperative Ergebnisse im Vergleich mit anderen klinischen Faktoren beeinflusst.

Ergebnisse:

Die Teamerfahrung hatte keinen Zusammenhang mit den Kurzzeitergebnissen, außer bei Infektionen der Inzisionswunden (surgical site infection, SSI). Andererseits war die Erfahrung des Operateurs mit der mittleren Operationsdauer und SSI-Rate assoziiert. Die Endpunkte der Lernkurve zur Reduzierung der mittleren Operationsdauer und der SSI-Rate ließen sich als 40 und 20 Fälle einer laparoskopischen Rektumresektion definieren. Im Gegensatz dazu war eine Anastomoseninsuffizienz nicht assoziiert mit der Erfahrung des Operateurs und sie zeigte die größte Korrelation mit einer totalen mesorektalen Exzision (TME).

Schlussfolgerung:

Die Erfahrung des Operateurs verbesserte die Operationsdauer und SSI. Andererseits stand eine distale Anastomose begleitet von TME in einer starken Korrelation zu einer Insuffizienz, dagegen war eine Korrelation zwischen Insuffizienz und Erfahrung des Operateurs nicht klar nachweisbar.

Abstract

Purpose:

Technical difficulties have been encountered in laparoscopic surgery for the treatment of rectal cancer. There are fewer studies about the learning curve for laparoscopic rectal resection.

Patients and Methods:

Between June 1995 and August 2007, 200 patients who were scheduled to undergo laparoscopic rectal resection for rectal cancer were enrolled in the study. Each surgeon’s operative experience was divided into three groups: 1–20 cases, 21–40 cases, and ≥ 41 cases. Furthermore, patients were divided chronologically into four groups of 50 patients each. This report describes the association between the learning curves (surgeon’s experience and team’s experience) and short-term outcomes such as operating time, complication rate, and hospital stay in the case of laparoscopic resection for rectal cancer. We also analyzed how the learning curve influences several postoperative outcomes compared with other clinical factors.

Results:

The team’s experience was not associated with short-term results except for surgical site infection (SSI). On the other hand, surgeon’s experience was associated with mean operating time and SSI rate. The endpoints of the learning curve for reducing mean operating time and SSI rate were defined as 40 and 20 cases of laparoscopic rectal resection. In contrast, anastomotic leakage was not associated with surgeon’s experience and showed the greatest correlation with total mesorectal excision (TME).

Conclusion:

Surgeon’s learning improved operating time and SSI. On the other hand, low level of anastomosis accompanied with TME was strongly related with leakage, and the association between leakage and surgeon’s learning was not clearly demonstrated.
