Abstract

Pain arising from pelvic viscera and perineum is frequently associated with discomfort and disability and caused by local trauma, inflammation and malignancy within the pelvis. Although various interventions have been proposed for the management of intractable perineal pain, their efficacy and applications are limited. The ganglion impar is a solitary retroperitoneal structure located at the level of the sacrococcygeal junction that marks the terminations of sympathetic chains. We propose that blockade of the ganglion impar is an effective method in the management of patient suffered from perianal pain due to advanced rectal cancer.
