Reattempting the Whipple: Surgical and Oncologic Outcomes After Failed Initial Resection.

Abstract

BackgroundPancreatoduodenectomy (PD) is the only curative treatment for pancreatic cancer. Neoadjuvant therapy (NAT) has enhanced survival, especially for downstaging advanced tumors, while also introducing complexities and new complications. Despite surgical advances, some PD attempts remain unsuccessful. The management of these cases is not well defined. This study analyzes outcomes of repeat PD performed by two high-volume surgeons following previously unsuccessful attempts.MethodsWe retrospectively analyzed patients with pancreatic neoplasm undergoing successful pancreaticoduodenectomy (2013-2024) at two high-volume centers under two experienced surgeons. Only cases with prior aborted PD attempts for non-metastatic disease were included. Data from institutional records provided outcomes on failure reasons, procedure timing, surgical details, and 90-day complications.ResultsOf the 858 PD cases, 18 patients (2.1%; 12 males, 6 females; median age 69 years) had prior unsuccessful PD attempts at other institutions. Initial tumors were borderline resectable (33.3%), resectable (22.2%), or locally advanced (22.2%). Main causes for initial failure were vascular involvement (41.2%) and tumor infiltration (17.6%). Median time between attempts was 246 days, with 77.8% receiving chemotherapy before the second attempt. The second procedure achieved R0 resection in 94.4% of cases. Major 90-day complications occurred in 23.5% of patients, with no perioperative mortality. Disease recurrence occurred in 38.9% within the first year.ConclusionRepeat PD after an aborted attempt is feasible in select patients at specialized centers. However, complication and recurrence rates emphasize the need for careful patient selection. Further research is needed to optimize management strategies.
