Chronic Liver Disease Increases Mortality Following Pancreatoduodenectomy.

ABSTRACT

According to the International Study Group of Pancreatic Surgery (ISGPS), data about the impact of pre-existing liver pathologies on delayed gastric emptying (DGE) after pancreatoduodenectomy (PD) according to the definitions of the International Study Group of Pancreatic Surgery (ISGPS) are lacking. We therefore investigated the impact of DGE after PD according to ISGPS in patients with liver cirrhosis (LC) and advanced liver fibrosis (LF). Patients were analyzed with respect to pre-existing liver pathologies (LC and advanced LF, n = 15, 6% vs. no liver pathologies, n = 240, 94%) in relation to demographic factors, comorbidities, intraoperative characteristics, mortality and postoperative complications, with special emphasis on DGE. DGE was equally distributed (DGE grade A, p = 1.000; B, p = 0.396; C, p = 0.607). Particularly, the first day of solid food intake (p = 0.901), the duration of intraoperative administered nasogastric tube (NGT) (p = 0.812), the rate of re-insertion of NGT (p = 0.072), and the need for parenteral nutrition (p = 0.643) did not differ. However, patients with LC and advanced LF showed a higher ASA (American Society of Anesthesiologists) score (p = 0.016), intraoperatively received more erythrocyte transfusions (p = 0.029), stayed longer in the intensive care unit (p = 0.010) and showed more intraabdominal abscess formation (p = 0.006). Moreover, we did observe a higher mortality rate amongst patients with pre-existing liver diseases (p = 0.021), and reoperation was a risk factor for higher mortality (p ≤ 0.001) in the multivariate analysis. In our study, we could not detect a difference with respect to DGE classified by ISGPS; however, we did observe a higher mortality rate amongst these patients and thus, they should be critically evaluated for PD.
