Perineal pain and anastomotic ischemia were improved after ganglion impar block

Abstract

Perineal pain can be intractable; past study reported the effectiveness of blockade of ganglion impar, superior hypogastric plexus and inferior mesenteric plexus. In this paper, we report a case in which post-sigmoidectomy perineal pain and anastomotic ischemia were improved after ganglion impar block. 48-year-old man who had had perineal pain and anastomotic ischemia was consulted to our department. His perineal pain got worse when he defecated. Fluoroscopic ganglion impar block was performed; the perineal pain was completely cured five months after and colonoscopy revealed improvement of anastomotic ischemia. In this case, anastomotic ischemia may have caused perineal pain and bearing down possibly got ischemia worse by means of activation of sympathetic nerve.
