Laparoscopy for staging and palliation of gastrointestinal malignancy.

The use of laparoscopy in the treatment of malignant diseases is one of the great advances of surgery in the last few decades. Its roles as a diagnostic modality, a staging tool, and a therapeutic avenue for the various malignancies of the abdominal cavity continue to expand. The benefits to cancer patients with regard to reduced morbidity and shorter hospitalizations are well established. As video, optical, insufflation, and instrumentation technologies advance further, laparoscopic techniques for the treatment of cancer can only multiply in depth and breadth.
