Laparoscopic screening of surgical candidates with pancreatic cancer or liver tumors

Background: Patients with colorectal or pancreatic cancers may have peritoneal implants which are too small to be detected by current radiologic imaging techniques. Since such implants often preclude surgical removal of the primary tumor or isolated metastasis, their detection prior to open abdominal exploration may spare patients the morbidity of a large abdominal incision when there is no benefit to resection and lifespan is limited.
