Enteral nutrition provides favorable postoperative outcomes for patients with pseudomyxoma peritonei: a retrospective study
GLAND SURGERY(2022)
Abstract
Background: Pseudomyxoma peritonei (PMP) is a rare malignancy, and many uncertainties regarding its treatment and prognosis still remain. The main treatment for PMP is cytoreductive surgery (CRS) combined with heated intraperitoneal chemotherapy (HIPEC), which can lead to intra-abdominal trauma and systemic reactions. Enteral nutrition (EN) is an important and beneficial perioperative option for major complicated abdominal surgery compared with total parenteral nutrition (TPN). However, the role of EN in PMP after surgery is still unknown. The purpose of this study was to analyze the effects of EN on postoperative outcomes in PMP patients. Methods: The perioperative clinical data of PMP patients from Xiangya Hospital of Central South University who accepted CRS plus HIPEC from January 2011 to December 2018 were collected and analyzed. The effects of EN on the nutritional status, postoperative complications, and hospital stay time of patients with PMP were studied. We further analyzed the risk factors affecting hospital stay and complications in PMP patients after surgery. Results: A total of 51 PMP patients accepted CRS and were enrolled in this study, including 25 cases in the EN group and 26 patients in the TPN group. The baseline demographic characteristics and preoperative nutritional status were not significantly different between the two groups. The postoperative absolute lymphocyte count (P<0.001), hemoglobin (P=0.016), and albumin (P<0.001) levels of the EN group were higher than those of the TPN group, but the postoperative hospital stay time (P=0.008) and the complication rate (P=0.03) in the EN group were less than those in the TPN group. Logistic regression analysis showed that age (P=0.031), American Society of Anesthesiologists (ASA) score (P=0.008), and EN (P=0.024) were independent risk factors for postoperative hospital stay in PMP patients. ASA score (P=0.006), number of prior operations (P=0.021), and EN (P=0.035) were independent risk factors for postoperative complications in PMP patients. Conclusions: EN support results in better outcomes and is an independent protective factor for the postoperative hospital stay time and complications of PMP patients.
