Background: Routine preoperative staging in pancreas cancer is controversial. We sought to evaluate the rates of diagnostic laparoscopy (DLAP) for pancreatic cancer.Methods: We queried the National Surgical Quality Improvement Program for patients with pancreas cancer (2005-2013) and compared groups who underwent DLAP, exploratory laparotomy (XLAP), pancreas resection (RSXN) or therapeutic bypass (THBP). We compared demographics, comorbidities, postoperative complications, 30-day mortality (Chi-square P < 0.05) and trends over time (R2 0-1).Results: We identified 17,138 patients (RSXN 81.8%, XLAP 16.5%, THBP 8.2%, and DLAP 12.9%), with some having multiple CPT codes. Only 10.3% (n = 1432) of RSXN patients underwent DLAP prior to resection. XLAP occurred in 49.5% of non-RSXN patients, of whom 67.1% had no other operation. The percentage of patients undergoing RSXN increased 20.3% over time (R2 0.81), while DLAP decreased 52.6% (R2 0.92). XLAP patients without other operations decreased from 4.2 to 2.4%, although not linearly (R2 0.31). Only 10.3% of XLAP had a diagnostic laparoscopy as well, leaving nearly 90% of these patients with an exploratory laparotomy without RSXN or THBP.Discussion: Diagnostic laparoscopy for pancreas malignancy is becoming less common but could benefit a subset of patients who undergo open exploration without resection or therapeutic bypass.
