Albumin Leakage Level during Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy Is Associated with Major Complications

The clinical consequences of perioperative albumin extravasation accompanying major abdominal surgery remain underexplored. We retrospectively reviewed the data of patients who underwent cytoreductive surgery (CRS) and hyperthermic intraoperative peritoneal chemotherapy (HIPEC). Parameters of albumin kinetics, including serum albumin concentration decrease (∆Alb) and extravasated albumin level (Alb_shift), were assessed from surgery until postoperative day (POD) 3. Logistic regression analysis identified factors associated with major complications. The association of albumin kinetics with major complications was evaluated using receiver operating characteristic (ROC) curve analysis. Serum albumin levels decreased during surgery and subsequently increased. Of the 121 analyzed patients, 25 (21%) developed major complications. The ∆Alb and Alb_shift during surgery and on POD 3 were greater in patients who developed major complications than in those who did not (12 ± 12 vs. 6 ± 14, <i>p</i> = 0.032, and 127.5 (71.9) vs. 48.5 (44.9), <i>p</i> < 0.001, respectively). Perioperative ∆Alb and Alb_shift were associated with major complications. The areas under the ROC curve of Alb_shift during the 3 days post-surgery and Alb_shift on POD 3 were 0.843 and 0.910, respectively. Alb_shift during the 3 days post-surgery and Alb_shift on POD 3 were correlated with complications (<i>p</i> < 0.05). In conclusion, perioperative albumin loss was associated with major complications in patients undergoing CRS and HIPEC. Alb_shift was associated with serious complications.
