    Abstract:
    Staging of pancreatic cancer still represents a challenge for surgeons involved in this field. Diagnostic methods of radiological imaging used routinely (CT, NMR, angiography) may understage this neoplasm. In fact, the presence of peritoneal or subglissonian hepatic micrometastases (< 2 cm) is a frequent surprise at laparotomy and forces the surgeon to use a palliative procedure. Actually this policy has not to be followed because the possibility to perform non-surgical palliation of jaundice or pain respectively by percutaneous radiological stent insertion and celiac alcoholization. In this viewpoint, preoperative staging has acquired an important role for a correct treatment, be it surgical or medical. Laparoscopy allows it to overcome the understaging produced by the more common diagnostic means, with the possibility to view directly the celomatic space and the surface of the abdominal viscera; moreover, during this procedure it is possible to perform a peritoneal washing to obtain other information about the cancer stage. In our experience, 56 patients were judged as resectable by radiologic methods; 31 were excluded from surgery by laparoscopy; 10 of the remaining 25 cases were submitted to radical resection. The operative resectability rate resulted in 40%, against 18% in cases where we submitted to surgery all the patients. Seven patients underwent peritoneal washing, always with a negative result; all were submitted to surgery and radically resected. In our opinion, laparoscopy and peritoneal washing represent useful tools in the staging of patients affected by pancreatic cancer.
