Ganglion Impar Block and Neurolysis for Perineal Pain in Anal Adenocarcinoma: A Case Report

Abstract

Background: Anal adenocarcinoma is a rare malignancy with symptoms including tenesmus, rectal bleeding, and pain during defecation. The pain can significantly reduce a patient's quality of life and there is currently no effective treatment for it. Ganglion impar block and neurolytic are one methods for managing pain in such cases. Case: A 60-year-old woman with anal adenocarcinoma and chronic pain in the anal region for two years despite oral medication underwent ganglion impar block and neurolytic treatment using a mixture of 96% alcohol and levobupivacaine 0.25%. Conclusion: Ganglion impar block with neurolysis using 96% alcohol can be an option for managing perineal pain, especially when previous medication therapy is ineffective. This combination is safe for patients and can reduce pain levels. Keywords: Impar Ganglion Block; Neurolysis; 96% Alcohol; Anal adenocarcinoma; Perineal pain; Pain management
