BACKGROUND: In patients with pancreatic or periampullary tumor, staging laparoscopy (SL) can detect metastases that are occult on computed tomography (CT), thereby precluding nontherapeutic laparotomy. Routine SL is not advocated, but some studies suggest its selective use. The aim of this study was to identify patients at risk for metastasis in whom SL could be beneficial. METHODS: A consecutive series of patients who underwent laparotomy for a suspected pancreatic or periampullary tumor were analyzed. We included patients with a suspected resectable solid lesion and a recent high-quality CT scan. Patients with and without an intraoperatively encountered metastasis were compared. Regression analysis was performed to examine the association between various predictors and metastasis. RESULTS: Data from 385 patients (mean age 63, 41% women) were analyzed. Distant metastasis was encountered in 79 patients (21%). Logistic regression analysis revealed the following key predictors for metastasis: tumor size on CT scan [odds ratio (OR) 1.43, 95% confidence interval (CI) 1.16-1.76 per millimeter increase], weight loss (OR 1.28, 95% CI 1.01-1.63 per doubling the kilograms), and history of jaundice (OR 2.36, 95% CI 0.79-7.06). In patients with a tumor ≥3 cm and severe weight loss (≥10 kg) and in patients with a tumor ≥4 cm and moderate weight loss (≥5 kg), the proportion of patients with metastasis was >40%. CONCLUSIONS: In patients with a suspected pancreatic or periampullary tumor, the tumor size, weight loss, and jaundice are key predictors of metastasis at exploration. SL might be beneficial in patients with a tumor ≥3 cm and severe weight loss and in those with a tumor ≥4 cm and moderate weight loss.
