Perioperative Management of Patients Undergoing Cytoreductive Surgery Combined with Heated Intraperitoneal Chemotherapy for Peritoneal Surface Malignancy: A Multi-Institutional Experience

Cytoreductive surgery (CRS) combined with heated intraperitoneal chemotherapy (HIPEC) is an established treatment for patients with pseudomyxoma peritonei. There is now increasing evidence for the use of CRS and HIPEC in the treatment of other peritoneal surface malignancies. There is currently no consensus on the perioperative management of this patient group. An international survey of practice was conducted using an online survey tool. Centers were identified from the list of delegates attending the Seventh International Workshop on Peritoneal Surface malignancy held in Uppsala, Sweden, in September 2010. Fully completed surveys were received from 29 of 41 identified centers (71 %). The survey covers the combined experience amassed by anesthesiologists caring for 8,467 patients undergoing cytoreductive surgery. Intraoperative fluid management, management of coagulopathy, management of the HIPEC phase of the operation, and postoperative analgesia caused the greatest difficulties for the anesthesia team with variation in management identified between different institutions. The incidence of epidural abscess in this patient group was found to be 1:2,139. Optimal preoperative, intraoperative, and postoperative care is crucial to diminish the complications in this complex treatment strategy. Multicenter collaboration is suggested to gain evidence on the best strategies for perioperative management. Further data collection needs to be undertaken to assess the safety of epidural anesthesia in this patient group.
