[Laparoscopic resections of malignant diseases of the gastrointestinal tract].

As the importance of laparoscopic surgery for benign diseases of the gastrointestinal tract continues to grow, the application of this approach in cases of malignancy remains controversial. Although the concept of cancer recurrence in the area of surgical wounds is not new, the incidence of port site recurrence is the most obvious concern. Indications and contraindications for surgery as well as a standardized nomenclature describing the type of laparoscopic procedures being performed are some other issues that need to be clarified. Complete laparoscopic procedures or the combination of laparoscopy with open techniques can offer advantages and disadvantages that surgeons will have to take into consideration when making decisions. The skill of the operating team and the extent of disease define the boundaries of laparoscopic surgery possible. The continued research as well as development of intelligent instruments and standardized techniques might give laparoscopy a clear role in the treatment of abdominal malignancies.
