PURPOSE/BACKGROUND: Cytoreductive surgery (CRS) is complex abdominal surgery that is used to treat peritoneal malignancy. CRS is associated with major morbidity and efforts to address this include optimisation of perioperative care. There is variation in international protocols on the nutritional management after CRS, in particular whether parenteral nutrition (PN) should be routinely or selectively administered.
HYPOTHESIS/AIM: This study assessed parenteral nutrition use, factors associated with PN requirement and nutritional outcomes in a centre that selectively uses PN after CRS.
METHODS/INTERVENTIONS: A retrospective analysis was undertaken on patients who underwent cytoreductive surgery ± hyperthermic intraperitoneal chemotherapy (HIPEC) at Peter MacCallum Cancer Centre between 1st January 2015 and 31st December 2020 using data entered into a prospectively maintained database. Patient characteristics, nutritional status, oncological parameters, operative details and postoperative outcome data were retrieved. Categorical variables were compared using the chi-squared test and continuous data was compared using a non-parametric Mann-Whitney U-test. A p-value <0.05 was considered statistically significant. Cox regression analysis was performed to identify independent predictors of requiring PN and postoperative weight change over admission.
RESULTS: A total of 222 patients who had CRS between were included (mean age 56 years; female 61.3%). Preoperative nutritional characteristics of participants included a mean body mass index (BMI) of 27.6 kg/m2 and the majority (77.9%) were not at nutritional risk pre-operatively with a Patient Generated Subjective Global Assessment (PG-SGA) score of category A. A high proportion of patients had surgery for colonic adenocarcinoma (58.1%), received HIPEC (87.4%) and achieved complete cytoreduction (82%). Postoperative parenteral nutrition was required for 65 patients (29.3%). The most frequent indication for PN was postoperative ileus (63.1%) with the mean (SD) time to commencing PN being postoperative day 5. Factors associated with the requirement for postoperative PN included preoperative albumin (OR 0.89; p = 0.015), weight loss >5% of body weight in the 6 months prior to admission (OR 2.2; p = 0.05), higher PCI score (OR 1.048; p = 0.005), number of anastomoses completed (OR 1.766; p = 0.017) and development of any postoperative complication (OR 2.71; p = 0.009). PN use was not associated with postoperative weight change.
CONCLUSION: Most patients undergoing CRS did not require post-operative PN. Nutritional and operative factors may identify patients who are likely to need PN after surgery. Selective use of PN did not impact on postoperative weight change.
