Zusammenfassung
Hintergrund
Neue Operationstechniken in der kolorektalen Chirurgie verfolgen das Ziel einer möglichst geringen Patientenbelastung bei mindestens äquivalenter und möglichst verbesserter Behandlungs- und Ergebnisqualität. Hochwertige klinische Studien sind in der Evaluation sinnvoll erscheinender Innovationen notwendig und sollen die Machbarkeit, aber auch die Vorteile (oder Nachteile) neuer Operationstechniken bewerten.
Fragestellung
Die laparoskopische Kolonkarzinomchirurgie ist durch eine Reihe exzellenter prospektiv randomisierter Studien hinsichtlich Sicherheit und onkologischer Qualität untersucht (COST-Study, COLOR-I, CLASICC). Die Patienten profitieren von den Vorteilen des geringeren Zugangstraumas, ohne Einschränkungen in der onkologischen Radikalität hinnehmen zu müssen. Können diese positiven Ergebnisse auf die Rektumkarzinomchirurgie übertragen werden?
Ergebnisse
In der Rektumkarzinomchirurgie konnten aktuell die Frühergebnisse der COLOR-II-Studie veröffentlicht werden, in der eindeutig nachgewiesen werden konnte, dass die laparoskopische Technik dem konventionellen offenen Vorgehen nicht unterlegen ist. Hinsichtlich Blutverlust, postoperativem Schmerzniveau, Krankenhausverweildauer und lateralem Sicherheitsabstand im distalen Rektumdrittel fanden sich signifikante Vorteile für die laparoskopische Operationstechnik. Die onkologischen Langzeitergebnisse (Lokalrezidivrate als primärer Endpunkt der Studie) zeigen ebenfalls einen günstigen Trend für die minimal-invasive Rektumchirurgie und werden demnächst publiziert.
Zusammenfassung
Die Sicherheit und die onkologische Qualität laparoskopischer Resektionsverfahren beim Rektumkarzinom sind durch klinische Studien gut belegt. In erfahrenen Zentren wird die laparoskopische Operationstechnik immer mehr zum Goldstandard in der Rektumkarzinomchirurgie.
Abstract
Background
Innovative surgical techniques in colorectal surgery aim to provide diminished surgical injury and at least equivalent or even improved quality of treatment and oncological results. High level clinical studies are mandatory to examine the feasibility and advantages (or disadvantages) of new operative techniques.
Objectives
Laparoscopic colonic resection for cancer has been investigated with respect to safety and oncological quality in various prospective randomized studies (COST study, COLOR-I and CLASICC). The minimally invasive procedure is feasible and safe which was demonstrated in many studies but can these results be extrapolated to laparoscopic rectal cancer surgery?
Results
The short term outcomes of the COLOR-II trial were published recently and laparoscopic resection for rectal cancer was not found to be inferior compared to open resection. Recovery after laparoscopic surgery was better than after open surgery. Laparoscopic surgery was found to have significant advantages with respect to blood loss, operating time, use of pain medication, early restoration of bowel function and reduction of hospital stay as well as the lateral safety margins in the distal third of the rectum. The long-term results focussing on local recurrence showed a positive trend in favor of laparoscopic rectal surgery and will be published shortly.
Conclusion
Laparoscopic total mesorectal excision (TME) appears to have clinically measurable short-term advantages in patients with primary rectal cancer based on the evidence of randomized studies. Laparoscopic rectal cancer resection may become the gold standard in the future.
