Patients with pancreatic adenocarcinoma benefit from staging laparoscopy.

BACKGROUND

Unnecessary laparotomy in patients with advanced pancreatic cancer may both compromise the quality of life and delay the initiation of more appropriate therapy. Very often, peritoneal small liver metastases and true local status cannot be fully determined without surgery. Laparoscopy may spare laparotomy and decrease morbidity for patients with nonresectable advanced disease. The aim of this study was to determine the impact of laparoscopy in patients with potentially resectable adenocarcinoma of the pancreas.

MATERIALS AND METHODS

We reviewed the records of patients undergoing pancreatic surgery at the University of Nebraska Medical Center from October 2001 to April 2005. A total of 59 patients were included in the study. All patients were staged radiographically with a high resolution helical computed tomography scan and their tumors were considered resectable. Thirty-seven patients underwent staging laparoscopy while 22 proceeded directly to laparotomy.

RESULTS

Of the 37 patients who underwent laparoscopic staging, 9 (24.3%) were detected to have metastatic disease or advanced tumor; the remaining 28 (75.7%) patients with negative laparoscopy proceeded to laparotomy. Of those, 24 patients (85.7%) underwent pancreatic resection with curative intent, while 4 patients had metastatic or locally advanced disease at subsequent laparotomy which was missed on staging laparoscopy (false negative rate of 14.3%). Of the 22 patients who proceeded directly to laparotomy, 16 (72.7%) received curative Whipple resection and 6 (27.3%) were found to have advanced disease and received bypass procedures or biopsy alone.

CONCLUSION

These findings suggest that staging laparoscopy is beneficial in a significant proportion of patients deemed resectable by routine noninvasive preoperative studies. We plan to add intraoperative laparoscopic ultrasound to our staging protocol in order to decrease the false negative rate.
