Abstract


Purpose: Although pancreatoduodenectomy (PD) in patients who have previously undergone gastrectomy is challenging, little is known about the clinical outcomes and the differences compared to those with conventional PD. We collected cases and conducted studies in retrospective review.

Methods: Of the 1,722 patients who underwent PD at Seoul National University Hospital between 2000 and 2014, 49 (2.8%) underwent previous gastrectomy. Clinical outcomes including operation-related factors and postoperative morbidities were analyzed.

Results: Among the 49 patients with curative surgery, 25 patients were male (51.0%) and the mean age was 64.7 years. Gastric cancer was the most frequent cause of previous gastrectomy (93.8%). With one-to-one propensity score matching analysis, lower preoperative body mass index (22.6 kg/m2 vs. 20.8 kg/m2, P = 0.002), higher EBL (390.0 mL vs. 729.5 mL, P = 0.027), and higher transfusion rates (10.2% vs. 36.7%, P = 0.002) were shown in the gastrectomy group. Operation time, postoperative hospital stay, and rate of clinically relevant pancreatic fistula were comparable.

Conclusion: Secondary PD after prior gastrectomy remains challenging, with higher EBL and rate of transfusion. However, when performed by experienced surgeons, the patients with or without previous gastrectomy show comparable postoperative clinical outcomes, such as similar duration of postoperative hospital stay and rate of postoperative pancreatic fistula.
