[The role of laparoscopy and peritoneal cytology in the preoperative staging of pancreatic carcinoma].
The staging of pancreatic cancer still represents a challenge for surgeons involved in this field; radiological diagnostic methods used routinely (CT, NMR, angiography) may under-estimate this neoplasm; in fact, the presence of peritoneal or subglissonian hepatic micrometastasis (< 2 cm) is a frequent surprise at laparotomy and force the surgeon to undertake a palliative procedure. This policy need not be followed because it is possible to perform non-surgical palliation of jaundice or pain respectively by percutaneous radiological stent insertion and coeliac alcoholisation. Pre-operative staging thus acquires an important role in the correct treatment, surgical or medical. Laparoscopy allows us to overcome the understaging of the more common diagnostic methods and view directly the coelomatic space and the surface of the abdominal viscera; moreover during this procedure it is possible to perform a peritoneal wash to obtain other information on the cancer stage. We judged 56 patients by radiological diagnosis; 31 were excluded from surgery by laparoscopy; 10 of the other 25 cases were submitted to radical resection. The resectability operative rate was 40%, compared with 18% if we had submitted patients to surgery. Several patients underwent peritoneal wash, always with negative results; all were submitted to surgery and radically resected. In our opinion, laparoscopy and peritoneal wash represent useful tools in the staging of patients affected with pancreatic cancer.
