Diagnostic Laparoscopy in the Preoperative Staging of Pancreatobiliary Cancer

A Prospective Study Investigating the Role of Diagnostic Laparoscopy in the Preoperative Staging of Pancreatobiliary Cancer

The purpose of this study is to evaluate the role of routine Staging Laparoscopy in patients with potentially resectable pancreatobiliary cancer.

To evaluate the role of routine staging laparoscopy in patients with potentially resectable pancreatobiliary cancer. All analyses are performed using SAS version 9.1.3 for Windows (SAS institute, Cary, NC). Clinical and pathological variables will be analyzed using the χ2 test (or Fisher's exact test) and the Student's t test, depending on the normality of the distribution. P-values of < 0.05 are considering statistically significant.

Inclusion Criteria:

1. Resectable pancreatobiliary cancer confirmed by radiologic studies (CT scan, MRI, PET-CT)

2. No evidence of distant metastasis

3. aged 15-80 year old

4. performance status (PS) of 0 or 1 on Eastern Cooperative Oncology Group (ECOG) scale

5. adequate organ functions defined as indicated below

   2. > Hb 8.0 g/dl
   3. > Plt 100 000/mm3
   4. < Cr 1.2 mg/dl
   5. > Ccr 60 ml/min/body
