Clinical outcomes of combined ganglion impar block and caudal epidural steroid injection in chronic perineal pain: a retrospective study

Aims: Chronic perineal pain is a complex and debilitating condition that often shows limited response to conservative treatment modalities. Ganglion impar block (GIB) and caudal epidural steroid injection (CESI) are established interventional techniques; however, clinical data on their combined use are limited. This study aimed to evaluate the effectiveness and safety of performing GIB and CESI concurrently in patients with chronic perineal pain.Methods: This retrospective study included 43 patients who underwent combined GIB and CESI in a single session. Demographic and clinical data were obtained from medical records. Pain intensity was assessed using the Visual Analog Scale (VAS) at baseline, 3 weeks, and 6 months after the procedure. Adverse events and the need for repeat interventions were also evaluated. Results: The study population consisted predominantly of female patients (81.4%), with a mean age of 41.79±14.10 years. Trauma was the most common pain etiology (62.8%). Median VAS scores decreased significantly from 8 [6–10] at baseline to 0 [0–8] at 3 weeks and to 2 [0–8] at 6 months (p
