Abstract

Oncologic chronic pain is often difficult to control, especially in anatomical areas with multiple and complex innervation, such as the pelvic/perineal region. The ganglion impar block (GIB) is a procedure with growing interest and varied applicability. It has been used in several benign and malignant causes of pelvic and perineal pain refractory to pharmacological treatment. We conducted a review of all articles published in PUBMED® until the 30th of October 2022 regarding GIB in oncologic pain. 19 articles were identified with a total of 278 patients. Both chronic cancer pain and chronic postcancer treatment pain patients were included. We reviewed the various techniques, approaches, and therapeutic options that were employed. No serious adverse effects were reported. GIB appears to be an effective and safe procedure that should be considered in patients with intractable perineal cancer-related pain.
