Hyperthermic Intraperitoneal Chemotherapy (HIPEC) is a surgical treatment that involves delivering heated chemotherapy directly into the abdominal cavity during surgery to treat cancers like peritoneal carcinomatosis, ovarian cancer, and colorectal cancer. The chemotherapy is heated to enhance its effectiveness and then circulated within the peritoneal cavity.

The procedure is typically done after cytoreduction surgery to remove visible tumors. HIPEC targets remaining cancer cells that may not have been removed during the surgery, offering a more localized and effective approach to treating peritoneal cancers.

Postoperative care includes monitoring for complications such as infection or chemotherapy-related side effects, managing pain, and ensuring the patient's recovery from both the surgery and chemotherapy.

HIPEC offers a promising treatment for patients with peritoneal cancers, significantly improving survival rates and offering the potential for long-term remission.
