Pancreatoduodenectomy (PD) is recommended in fit patients with a carcinoma (PDAC) of the pancreatic head, and a delayed resection may affect survival. This study aimed to correlate the time from staging to PD with long-term survival, and study the impact of preoperative investigations (if any) on the timing of surgery. Data were extracted from the Recurrence After Whipple's (RAW) study, a multicentre retrospective study of PD outcomes. Only PDAC patients who underwent an upfront resection were included. Patients who received neoadjuvant chemo-/radiotherapy were excluded. Group A (PD within 28 days of most recent preoperative computed tomography [CT]) was compared to group B (> 28 days). A total of 595 patents were included. Compared to group A (median CT-PD time: 12.5 days, interquartile range: 6-21), group B (49 days, 39-64.5) had similar one-year survival (73% vs. 75%, = 0.6), five-year survival (23% vs. 21%, = 0.6) and median time-todeath (17 vs. 18 months, = 0.8). Staging laparoscopy (43 vs. 29.5 days, = 0.009) and preoperative biliary stenting (39 vs. 20 days, < 0.001) were associated with a delay to PD, but magnetic resonance imaging (32 vs. 32 days, = 0.5), positron emission tomography (40 vs. 31 days, > 0.99) and endoscopic ultrasonography (28 vs. 32 days, > 0.99) were not. Although a treatment delay may give rise to patient anxiety, our findings would suggest this does not correlate with worse survival. A delay may be necessary to obtain further information and minimize the number of PD patients diagnosed with early disease recurrence.
