Operative Re-Intervention following Pancreatoduodenectomy: What Has Changed over the Last Decades.

ABSTRACT

Background: To investigate changes over the last decades in the management of postoperative complications following pancreatoduodenectomy (PD) with special emphasis on reoperations, their indications, and outcomes. Methods: 409 patients who underwent PD between 2008 and 2021 were retrospectively analyzed with respect to their need for reoperations (reoperation, n = 81, 19.8% vs. no reoperation, n = 328, 80.2%). The cohort was then compared to a second cohort comprising patients who underwent PD between 1989 and 2007 (n = 285). Results: 81 patients (19.8%) underwent reoperation. The main cause of reoperation was the dehiscence of pancreatogastrostomy (22.2%). Reoperation was associated with a longer duration of the index operation, more blood loss, and more erythrocyte concentrates being transfused. Patients who underwent reoperation showed more postoperative complications and a higher mortality rate (25% vs. 2%, p < 0.001). Compared to the earlier cohort, the observed increase in reoperations did not lead to increased mortality (5% vs. 6%, p = 353). Conclusions: The main cause for reoperation has changed over the last decades and was the dehiscence of pancreatogastrostomy. Associated with a leakage of pancreatic fluid and clinically relevant PF, it remains the most devastating complication following PD. Strategies for prevention and treatment, e.g., by endoscopic vacuum-assisted-closure therapy are of utmost importance.
