Gastrectomy history as a predictor of post-hepatectomy complications.

Abstract

The effect of a history of gastrectomy on patients undergoing hepatectomy is unclear. We investigated the relationship between postoperative complications of Clavien-Dindo grade III or higher and a history of gastrectomy in patients undergoing hepatectomy. The subjects of this retrospective analysis were 474 consecutive patients who underwent hepatectomy at our institute for hepatic malignancy, classified into groups of those with or without a history of gastrectomy and those with or without postoperative complications. We compared the clinicopathological factors between the groups. There were no hospital deaths. Gastrectomy history was identified in 22 patients (4.6%) and was significantly associated with advanced age, low body mass index, male sex, decreased serum albumin level, decreased hemoglobin level, low PNI, low CONUT score, high incidence of postoperative complications, and longer hospital stay. Multivariate analyses revealed that the independent risk factors for postoperative complications were gastrectomy history, an albumin-bilirubin score of 2/3, primary liver cancer, high serum creatinine level, advanced age, and prolonged operation time. Gastrectomy history was an independent predictor of postoperative complications in patients undergoing hepatectomy for hepatic malignancies. Patients with a history of gastrectomy were likely to suffer postoperative bile leakage and pneumonia.
