Analgesia for Gynecologic Oncologic Surgeries: A Narrative Review

Abstract

Purpose of review: Gynecologic oncologic malignancies are amongst the most common cancers affecting women across the world. This narrative review focuses on the current state of evidence around optimal perioperative pain management of patients undergoing surgeries for gynecologic malignancies with a specific focus on cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC).

Recent findings: Recent improvements in postoperative pain management following all types of gynecologic procedures, including minimally invasive, open-abdominal, or CRS + HIPEC, have been implemented through enhanced recovery after surgery (ERAS) protocols. These protocols encompass the use of preemptive analgesia, neuraxial and regional techniques, local anesthetic infiltration, and multimodal analgesia. The severity of postoperative pain varies for minimally invasive cancer surgery to open debulking procedures. Therefore, an individualized perioperative analgesic plan is critical depending on the surgical approach. For CRS + HIPEC, neuraxial techniques such as thoracic epidurals and opioid sparing multimodal analgesics have shown efficacy in the perioperative period. However, future research is needed as many of these patients develop chronic pain with very limited research done in this realm.
