BACKGROUND: The aim of this study was to assess whether the lack of a radiological mass in patients with periampullary malignancies led to protracted diagnosis, delayed resection, and an inferior outcome.
METHODS: The departmental database was interrogated to identify all patients undergoing pancreatoduodenectomy during the period 2000-2014. The absence of a mass on cross-sectional and endoscopic ultrasound was noted. The interval between imaging and surgery was evaluated and related to the absence of a mass. The relationship between mass/no mass and the pathological profile was also assessed.
RESULTS: Among 490 patients who underwent pancreatoduodenectomy for periampullary malignancies, masses were detected in 299 patients. Patients with undetected mass on either endoscopic ultrasonography (EUS) or computed tomography (CT)/magnetic resonance imaging (MRI) had a longer median interval from initial imaging to resection than detected mass with no difference in survival (66 vs. 41 days, p = 0.001). The absence of a mass was more common in cholangiocarcinomas (p < 0.001). The absence of a mass on imaging was associated with smaller size on final histopathology (2.4 vs. 2.8 cm; p < 0.001).
CONCLUSIONS: The absence of a mass with all modalities in patients with a periampullary malignancy leads to a delayed diagnosis without a significant effect on survival.
