Objective:
To test the hypothesis that laparoscopic staging improves outcome in patients with peripancreatic carcinoma compared to standard radiology staging.
Summary Background Data:
Diagnostic laparoscopy of peripancreatic malignancies has been reported to improve assessment of tumor stage and to prevent unnecessary exploratory laparotomies in 10% to 76% of patients.
Methods:
Laparoscopy and laparoscopic ultrasound were performed in 297 consecutive patients with peripancreatic carcinoma scheduled for surgery after radiologic staging. Patients with pathology-proven unresectable tumors were randomly allocated to either surgical or endoscopic palliation. All others underwent laparotomy.
Results:
Laparoscopic staging detected biopsy-proven unresectable disease in 39 patients (13%). At laparotomy, unresectable disease was found in another 72 patients, leading to a detection rate for laparoscopic staging of 35%. In total, 145 of the 197 patients classified as having "possibly resectable" disease after laparoscopic staging underwent resection (74%). Average survival in the group of 14 patients with biopsy-proven unresectable tumors randomly allocated to endoscopic palliation was 116 days, with a mean hospital-free survival of 94 days. The corresponding figures were 192 days and 164 days in the 13 patients allocated to surgical palliation.
Conclusions:
Because of the limited detection rate for unresectable metastatic disease and the likely absence of a large gain after switching from surgical to endoscopic palliation, laparoscopic staging should not be performed routinely in patients with peripancreatic carcinoma.
