Estimation of risk of major complications after hepatic resection.
To identify the risk factors predicting major postoperative complications from among preoperative and intraoperative variables, an extensive retrospective analysis of 209 patients who underwent hepatic resections was performed using multivariate logistic regression. The major complications were defined as liver failure, intractable ascites and pleural effusion, intraperitoneal infection, intra-abdominal hemorrhage requiring reoperation, major bile leakage, and gastrointestinal tract bleeding. First, detailed pre- and intraoperative data including medical history, laboratory data, portion and extent of hepatectomy, operative time, and amount of blood loss were univariately analyzed. Next, any significant variables were multivariately analyzed using the logistic regression method. Diabetes, increased intraoperative blood loss, resection of segment 8, and an increased serum blood urea nitrogen level were independent and significant variables predicting major postoperative complications. A higher level of serum cholesterol and a procedure involving a portion of left lateral segment were found to decrease the risk. Both more careful operative procedures and intensive management of DM and renal dysfunction in the perioperative period could result in a better quality of life after hepatic resection.
