Abstract

OBJECTIVE: The aims of this study were to verify whether the selective use of staging laparoscopy can prevent unnecessary laparotomy and to find a surrogate marker for surgical unresectability in patients with potentially or borderline resectable pancreatic cancer.

METHODS: Group A consisted of consecutive 33 patients evaluated between 2005 and 2006 and who directly underwent open laparotomy for planned surgical resection. Group B consisted of consecutive 61 patients evaluated between 2007 and 2009 and of whom 16 patients (26%) had a staging laparoscopy due to the presence of high-risk markers of unresectability defined as carbohydrate antigen 19-9 level 150 U/mL or greater and tumor size 30 mm or greater.

RESULTS: The frequency of unnecessary laparotomies for occult distant organ metastasis was significantly different between groups A and B (18% and 3%, respectively; P = 0.021). Of 16 patients who underwent staging laparoscopy in group B, 5 patients (31%) had occult metastases. The multivariate analysis showed that the presence of high-risk markers and extrapancreatic plexus invasion on multidetector-row computed tomography were significant independent risk factors for unresectability.

CONCLUSIONS: The presence of high-risk markers was associated with surgical unresectability in patients with potentially or borderline resectable pancreatic cancer. The selective use of staging laparoscopy decreased the frequency of unnecessary laparotomy by detecting minute metastases.
