Abstract Cytoreductive surgery with intraperitoneal hyperthermic chemotherapy via a moderately invasive technique is a procedure used for treating colon and ovarian neoplasms, and this approach has widely documented benefits in this area. However, in patients with gastric adenocarcinoma, the potential benefit of this approach has not been fully demonstrated, and little evidence is available. This report describes a patient with gastric cancer who underwent cytoreduction and HIPEC and the perioperative management of this patient, with emphasis on the intraoperative course from an anesthetic point of view and the immediate and early postoperative follow-up. This type of report will generate knowledge documenting behaviors and outcomes in this particular population that can potentially benefit from this therapy.
